DE102007048406B4 - Child seat for installation in a vehicle against its direction of travel - Google Patents

Abstract

The child seat (1) has a backrest (4) including head support is attached to seating (3) in seat direction of the rearward edge. A lateral sofa, arm rest and body back rest and a bracket particularly displacement bracket (20) are also provided for supporting the front side of the child seat into a distance from the back rest of vehicle seat. The displacement bracket is locked or engaged in multiple positions such that movement is completely stopped in a movement, particularly in turning direction.

Description

The invention is directed to an opposite to the direction of travel can be installed in a vehicle, placed on an on-board seat child seat, with a seat at the rear in the seat direction edge, a backrest, possibly together with headrest, connects, and possibly with lateral ear, Arm and / or trunk backrests and with a on the front in the sitting direction, free edge of the seat projecting bracket (spacer bracket) for supporting the front of the child seat at a distance in front of the backrest of the vehicle seat, wherein the spacer bracket has an approximately U-shaped basic shape with two mutually mirror-symmetrically arranged legs and a same having interconnecting central web and a transverse to the direction axis (pivot axis) is pivotable, wherein the spacer bracket is lockable in several positions or latched, so its movement is completely inhibited in at least one pivoting direction t, wherein the locking function causes an optimally adjusted position of the spacer bracket can not adjust itself by pivoting is made impossible to the front edge of the child seat under the influence of external pressure forces.

A large proportion of accidents is associated with a sudden deceleration of the vehicle concerned, with the inertial forces acting on the occupants endeavoring to move them forward within the delayed vehicle, ie in the direction of travel. The usual countermeasure are safety belts for adults, but especially for children. However, especially children often try to get rid of the disturbing belt at least partially and at least slip out of the shoulder straps to increase their freedom of movement. However, in the event of an accident, the risk of serious abdominal injuries increases significantly. Therefore, some parents prefer the use of such child seats in their car, which can be installed against the direction of travel, because in such a case of a head-on collision, the backrest of the child seat reliably intercept the child's body, even if the child should not be fully properly strapped. Such child seats are even required in some states, for example in Sweden.

The reversed installation of child seats on the rear seats of a vehicle, however, has some special features. A first special feature is that the child seat can not be moved quite close to the backrest of the vehicle seat, so that the child finds sufficient space for his legs. Another aspect is the adequate stabilization of the child seat relative to the vehicle. On the one hand, in this case, there is no intimate contact between the backrest of the child seat and the backrest of the vehicle's seat. On the other hand, the center of gravity of a child sitting in the child seat is much farther away from the seat back of the vehicle seat than in the conventional child seats. Thus, a child seat installed counter to the direction of travel could - both with appropriate accelerations of the vehicle - both tilt backwards - towards the vehicle's seat back - and forward - under temporary compression of the padded seat of the vehicle seat.

That is why in the DE 20 2004 017 276 U1 already a bracket has been proposed in front of the front edge of the seat, which is bent upwards at a distance in front of the seat. This can be cranked out with a spindle from the seat; However, during operation of the vehicle vibrations are generated by the engine and transmitted to the vehicle chassis, whereby this spindle could adjust itself in an undesired manner, so that it is unable to do its job - the support of the seat on the backrest of the vehicle seat - to fulfill reliably.

The WO 2005/108155 A2 does not relate to a child seat with a seat, backrest and headrest, but a system for mounting a baby seat in a vehicle. However, a baby lying in an infant carrier does not protrude - as in a "normal" child seat - the lower leg of the child from the knees on the front edge of the seat, but the baby has enough space to put his legs completely in the infant carrier.

Also from the EP 1 369 294 A1 Previously known mounting base is not suitable for mounting a child seat against the direction of travel, but only for the installation of a child seat in the direction of travel. Because there is indeed a U-shaped bracket provided; However, this protrudes directly on the horizontal mounting surface of the aufzusetzenden seat, so that here also no room for the legs of a child remains.

WO 85/00563 A1 discloses a fastening device for a child seat, but with the child seat is not placed on an on-board seat, but hovers above the leg or foot space between the front passenger seat and the dashboard. For this purpose, rods are used, but no spacer bracket with approximately U-shaped basic shape.

The EP 1 671 839 A1 does not relate to a child seat which can be installed counter to the direction of travel in a vehicle, but only a mounting plate for a seat that can obviously be installed in the direction of travel. The bracket can only be extended approximately within its plane relative to the mounting plate. For an adaptation to differently inclined backrests of vehicle seats is not possible.

The DE 697 06 121 T2 describes a child seat with a support frame for placement on a vehicle seat, and with a hinged to the support frame bracket, wherein the bracket forms a support arm against the backrest of the seat. However, with this arrangement, when installed, there is not enough space between the front edge of the seat and the back cushion of the onboard seat to allow a child to place their lower legs and feet there. In addition, in this arrangement, the previously known bracket always protrudes and pivots upward in the manner of a support bracket over the child seat. As a result, the seat is only partially accessible; both the setting of the child and its getting up or lifting is hampered.

From these disadvantages of the prior art described results in the invention initiating problem, a generic child seat for older children, which are no longer in a baby seat, so educate that when installing the child seat against the direction of travel enough foot clearance for the child between the front edge the seat of the child seat and the back pad of the vehicle seat remains, the child should neither take the seat nor to be hindered when getting up or lifting by a strap.

The solution to this problem is achieved in a generic child seat with the features of claim 1, characterized in that the ends of the spacer bracket at a plurality, laterally offset from each other points connected to a pivot axis or are mounted on such, which is located below the underside of the seat near the lower footprint of the child seat, which further has a length which corresponds approximately to the width of the child seat, and which extends between two lower side, runner-like side shields of the child seat chassis.

This spacer is even on the backrest of the vehicle seat and is supported and thus the associated child seat from it, so that on the one hand space for the child's legs is created and on the other hand excluded tilting of the child seat towards the back of the vehicle seat is. For this purpose, the spacer bracket rests against the backrest of the vehicle seat not only in its lower region, but also in its upper region, at least approximately half the height of the backrest of the vehicle seat, while on the other hand the child seat rests with its underside on the seat cushion of the vehicle seat , Since the average angle between backrest and seat surface of a seat is varied and in some cases even adjustable for different vehicle types, the spacer bracket is adjustable and can thereby be adapted to the different types of vehicle seats. Finally, the locking or locking function causes that an optimally adjusted position of the spacer bracket can not create automatically. It should be noted that the spacer bracket with the seat cushion of the vehicle seat transmits forces only in the compression direction, but not in the pulling direction. Therefore, it is not necessary, the spacer bracket in its two possible directions of movement - to the seat cushion and away from this - set or lock; Rather, it is sufficient if a compression or a pivoting is made impossible to the front edge of the child seat under the action of external pressure forces; for an automatic extension or pivoting away of the spacer bracket missing the one hand, the required external tensile forces; On the other hand, such a movement would also be uncritical, because then the child seat would then only pressed the stronger against the backrest of the vehicle seat.

By the spacer bracket is pivotable about an axis extending transversely to the direction of travel, its inclination angle relative to the underside or footprint of the child seat can be varied according to the different intermediate angle between the backrest and seat cushion adapted to different vehicle seats.

It is advantageous if the pivot axis is located near a lower-side contact surface of the child seat, and / or approximately below the front edge of the child seat. Thus, the pivot axis is in the vicinity of that area where meet the backrest and seat cushion of the vehicle seat. This has the advantage that the spacer bracket can be pivoted approximately parallel to the backrest for each type of vehicle seat, in order to be able to support it on the one hand over its entire surface and, on the other hand, without excessive local pressure.

By the pivot axis between two underside, runner-like side shields of the child seat chassis, it can be firmly anchored to the chassis of the child seat, and in view of the increased length of the pivot axis, which corresponds approximately to the width of the child seat, is enough space around the Spacer bar at several laterally staggered points with the pivot axis to connect or store at this, so that a distortion of the spacer bracket is not to be feared even with strong lateral loads.

The pivot axis and / or the spacer bracket may be formed as a tube to save weight, but without weakening the stability of the component in question.

Preferably, the two ends of the spacer bracket are connected to the preferably tubular pivot axis, for example. Welded. As a result, the pivot angle of the spacer bracket transmits to the pivot axis, so that, for example, a locking device can be connected to the pivot axis. The pivot axis itself is in this case rotatably connected in the region of its ends to the child seat chassis, for example via simple slide bearings, in particular by means of engaging in a tubular pivot axis stub axle, which are fixed to the chassis of the child seat.

The invention recommends that the spacer bracket from its attachment or pivot point, in particular from the pivot axis, seen from initially extends approximately horizontally in the seat direction forward. This section of the spacer bracket follows approximately the rear region of the vehicle's seat cushion. The length of this section, viewed in the direction of travel, affects the distance between the free front edge of the seat of the child seat and the backrest of the vehicle seat and therefore significantly determines the freedom of movement for the legs and feet of the child. This section should therefore correspond approximately to the sum of the desired distance between the back of the vehicle seat and the free front edge of the seat of the child seat on the one hand and the horizontal distance between just this free front edge of the seat of the child seat and the pivot axis.

At a distance in front of the free front edge of the seat of the spacer bracket is bent upwards and then follows from this area, the backrest of the vehicle seat to cling or support there. Preferably, the bend has a relatively large bending radius of about 5 to 30 cm, in particular about 10 to 20 cm, in order not to deform the tube cross-section in this area.

Overall, the Umbiegungswinkel the spacer bracket should be about equal to 90 ° or greater, preferably equal to 95 ° or more, in particular equal to 100 ° or more, and on the other hand 140 ° or less, in particular 130 ° or less. Thus, the invention takes into account the fact that the backrest of a vehicle seat is usually tilted slightly back to allow a comfortable seating position.

Furthermore, the invention provides that the spacer bracket extends upwards to approximately at the level of the upper edge of lateral armrests. Since the center of gravity of a child sitting in the child seat is approximately in the pelvic area, so approximately at the height of the armrests, the distance bracket therefore projects up to the center of gravity of the child with child seat up and can initiate a corresponding acceleration force of torques almost freely in the backrest of the vehicle seat ,

At its uppermost, peripheral end, the spacer bracket has a section which follows an approximately horizontal, approximately straight stretched, preferably transverse to the direction of travel course. This is responsible, if necessary to distribute stronger acceleration forces over a corresponding area and to initiate with reduced pressure load in the backrest of the vehicle seat. In this case, this upper portion of the spacer bracket corresponds to the central web of the approximately U-shaped bracket, which connects its two legs together.

These two legs of the spacer bracket, in turn, initially converge toward each other, as viewed from its uppermost or free, peripheral end, until approximately in the region of a bend from an approximately vertical section into an approximately horizontal section. Thus, the spacer bar is seen from top to bottom increasingly slimmer and leaves in the area of his bend much room for the feet of the child.

Approximately in the region of the bend between the approximately vertical section and the approximately horizontal section, the two legs of the spacer bracket have a minimum mutual distance and diverge from there to the pivot axis again from each other, so that the connection and / or connection points with the pivot axis 20 to 30 cm, whereby the spacer bracket overall receives a high stability and in particular is extremely torsionally rigid.

On the pivot axis, a horizontal portion of the spacer bracket approximately opposite adjusting lever is also arranged, in particular rotationally fixed and / or rigidly connected to the pivot axis, preferably welded thereto. Accordingly, while the pivot axis receives all forces of the spacer bracket, with the exception of the torques about just this pivot axis, it is up to the adjusting lever to derive these torques to the chassis of the child seat. The lever can be stretched straight Hollow profile may be formed, preferably with an elongated, upstanding cross-section, so that the lateral, preferably flat and mutually parallel surfaces of the profile, if necessary, can also transmit higher torques about the pivot axis without deformation. For connection to the pivot axis of this profile may have two mutually aligned bores or recesses, preferably in the straight, mutually parallel sections through which the pivot axis is inserted therethrough. In the context of the connection of these two parts, two weld seams result, which in each case follow the course of a flat circle and are easy to manufacture.

Preferably, the adjusting lever is approximately parallel to the seat direction, in particular along or within the vertical plane of symmetry of the child seat. With great advantage, the lever extends approximately horizontally in the direction of travel; He finds it below the underside of the seat space and freedom of movement to be able to be pivoted to a limited extent if necessary. He should reach down to just below the backrest, so that he is easily accessible with built-in seat below the then in the direction of travel forward facing backrest.

By the adjusting lever in the region of its free end relative to the chassis of the child seat in different positions can be determined, the inclination angle of the spacer bracket relative to the underside of the child seat can be set or adjusted as needed.

This determination of the adjusting lever is a part of the same for engagement and / or locking in one or more recesses on the chassis of the child seat. This is preferably at least one extension of the adjusting lever, which may be directed for example approximately radially relative to the longitudinal axis of the locking lever. For reasons of symmetrical power dissipation, two such extensions can be provided, preferably each other - with respect to the longitudinal axis of the adjusting lever approximately diametrically opposite, in particular lying in a common escape.

The counterpart for latching at least one part, in particular extension, of the adjusting lever forms a row of recesses, depressions or the like anchored to the chassis of the child seat, approximately tangentially to the swivel axis to arcuately extending around the swivel axis, wherein at least one part, in particular extension, of the Adjusting lever in different positions of the same engage and / or can engage. Since the length of the adjusting lever corresponds approximately to the depth of the child seat in the direction of travel, on the other hand, the required adjustment angle is only a few degrees, this row may possibly be formed completely straight, although they functionally should follow a circular arc about the pivot axis whose radius is about the length corresponds to the adjusting lever.

At least one row of such recesses may be arranged on an elongated or elongate element having a roughly or predominantly vertical profile. This alignment results from the approximately horizontal course of the adjusting lever and the perpendicular orientation of the row of recesses.

All torques transmitted by the spacer bracket via the pivot axis to the adjustment lever are transformed into forces at introduction into the elongated member via a detent or engagement mechanism which are directed predominantly or exclusively longitudinally with respect to that member and therefore do not cause bending stress thereon , Therefore, it is possible to attach at least one such elongated or elongate member to a transverse to the direction of travel strut of the child seat chassis or to hold between two such struts, which take over these forces and then forward the actual chassis. If at least one elongate or elongated element has a planar shape, it may be joined to one or more struts with a likewise planar weld.

At least one row of recesses can be realized as a row of teeth, wherein at least one extension of the adjusting lever can optionally engage in one of the interspaces between each two adjacent teeth. The teeth can be most easily formed by a tooth-shaped blank of a flat metal strip. The tips of the teeth should show approximately in or against the direction of the pivot axis, if a latchable therein extension is arranged laterally on the adjusting lever.

To adjust the adjusting lever, at least one extension thereof is manually lifted out of a gap between two adjacent teeth and can then be displaced freely in front of the teeth along the row of teeth until the desired position is reached. For this purpose, a degree of freedom between extension and row of teeth is required, which can be realized either by an adjustable mounting of the extension or the row of teeth.

If - as the invention further provides - the teeth have a sawtooth profile, so can the adjustment in one direction - eg. Towards greater inclination angles between spacer bracket and footprint of the child seat - Be effected without loosening a lock, while in the opposite direction of adjustment, a manual lifting at least one extension of the row of teeth is required and an automatic adjustment in this direction is therefore not possible.

The freedom of movement between at least one part or extension of the adjusting lever on the one hand and the row of recesses or teeth on the other hand is achieved in that at least one extension of the adjusting lever is displaceably mounted, preferably in approximately radial direction, relative to the pivot axis and / or approximately axial direction, relative to the longitudinal axis of the adjusting lever. This adjustment is thus approximately perpendicular to the movement path of the adjusting lever itself.

In order to maintain the once set angle of inclination between spacer bracket on the one hand and footprint of the child seat on the other hand, care must be taken to ensure that at least one thereby engaging in a recess and / or in a tooth gap extension of the adjusting lever can not solve automatically from the recess or depression. For this purpose, it is biased by spring force, preferably in the direction of the row of recesses, in particular in approximately radial direction from the pivot axis to the outside and / or approximately axial direction of the longitudinal axis of the adjusting lever, in particular of its connection to the pivot axis to his free end. This spring element is oriented so that it tends to pull at least one extension into the bottom of a recess or depression.

The invention is further characterized by a manually operable element for displacing at least one extension of the adjusting lever, preferably against the force of a prestressed spring. This element makes it possible, if necessary, to solve the latching and then to be able to adjust the spacer bracket completely freely in both pivoting directions.

The manually operable element for displacing at least one extension of the adjusting lever may be formed as a push button, which is mounted within the tubular adjusting lever and coupled or connected to at least one extension thereof. Simple pressure on this element thus moves within the tubular adjusting lever a this transversely passing pin whose over the two flat side surfaces of the adjusting out protruding ends serve as protruding extensions and can engage in each row of teeth. A spring intending to press this pin in the opposite direction can be received beyond the pin, that is to say within the adjusting lever, and in turn be supported by a rearward end on a firmly anchored element passing through the tubular adjusting lever.

The anchoring of the child seat could indeed be effected with the vehicle's belts. However, in view of the far forward displaced center of gravity of the occupied child seat, it seems advantageous to provide in the region of the spacer bracket, preferably laterally adjacent to its approximately horizontally extending portion, one or preferably two elements for anchoring the child seat connected to the vehicle chassis bow-shaped anchoring points (anchoring brackets) , Such anchoring is able to take, for example, extreme lateral forces, as they can occur during rapid cornering and / or strong lateral inclination or inclination of the vehicle, while in such a case an on-board belt may not prevent a lateral displacement of the child seat can. This is one or preferably two hook-shaped elements which embrace an anchoring bracket, if necessary together more or less completely. At least one such hook-shaped element can be movable in order to be able to be released from the anchoring bracket when required.

In order to adapt to different types of seats and / or vehicles, the distance of the / the element (-e) for anchoring the child seat on the vehicle's latches relative to the front edge of the child seat be adjustable, in particular by a telescopically extendable nature of the connection between the anchoring elements and the child seat -Chassis. On the other hand, such, nested and pulled apart profiles in different intermediate positions should be locked against each other, so that a set position can not change automatically. Such a locking can be effected, for example, by means of one or more transverse pins, which can / can engage in one of a plurality of recesses, in particular bores of the contiguous or each other guided rails or profiles. It may also be transversely or radially with respect to the respective profile longitudinal axis against outwardly urging compression springs adjustable elements, eg. With a dome-shaped front side, which are manually pressed into the profile in question to solve a catch, and automatically again snap to the outside, when facing two holes in a common escape in two telescopically movable profiles.

Such anchoring points, in particular hanger, on the vehicle body are now standardized (eg ISOFIX) and linden in newer Vehicle types in the region of the slot between the backrest and seat of a vehicle seat. If these anchoring points are used, they form, so to speak, pivot points around which the child seat can pivot - either upwards in the direction of the backrest or down into the seat cushion. While the former, upward pivotal movement is avoided by the spacer bracket according to the invention, however, such a spacer bracket is not able to avoid a temporary pivoting down of the child seat under compression of the seat cushion. Therefore, at least one downwardly projecting support leg is arranged on the chassis of the child seat, preferably on a transverse strut thereof, in the region of the backrest. This possibly gets in contact with the floor of the passenger compartment and prevents further lowering of the child seat.

For the purpose of adaptation to vehicle seats with different seat height, the length of at least one support leg should be adjustable. For this purpose, the support leg can be formed telescopically extendable. A lock should also be provided and can either be rastered or stepless. In the former case, at least one telescopic tube may comprise a series of recesses into which an element guided adjustably in the other telescopic tube radially with respect to its longitudinal axis can engage, for example under the influence of an internal spring. A stepless adjustment could, for example, be realized in that in the outer telescopic tube, a bore is provided with internal thread, wherein an adjusting screw is screwed, which presses with its front end frictionally against the outside of the inner telescopic tube.

Finally, it is the teaching of the invention that at least one support leg is removable or folded away, preferably zoom on the underside of the seat of the child seat. In this case, the dimensions of the child seat according to the invention for its storage and / or transport can be reduced in order to reduce the space required.

Further features, details, advantages and effects on the basis of the invention will become apparent from the following description of a preferred embodiment of the invention and from the drawing. Hereby shows:

1 a child seat according to the invention for installation in a vehicle counter to the direction of travel, with a spacer bracket for support on the back cushion of a car seat, from a side perspective;

2 the child seat off 1 seen from a viewing angle from the bottom of the spacer bracket forth;

3 take a look at the spacer bar of the child seat 1 , seen from the top, from the top;

4 a perspective view of a rear part of the chassis of the child seat 1 , viewed from the backrest thereof, wherein an actuating element designed as a handle for manually adjusting the distance bracket can be seen; such as

5 about one of the 4 corresponding part of the chassis of the child seat 1 from a slightly different perspective, and without the handle of the actuator for manually adjusting the distance bracket.

The in 1 shown child seat 1 Depending on the version, it is suitable for children up to 3 years or for children up to 12 years. It consists in the illustrated embodiment of a chassis 2 , the actual seat 3 , an adjoining backrest 4 with a head supporting area, as well as side armrests 5 , Side or trunk rests 6 and earrests 7 ,

The chassis 2 includes at the bottom of two skid-shaped side panels 8th , Which run approximately parallel to each other in the direction of travel and each with an approximately flat bottom 9 are provided for placing on the seat cushion of a vehicle seat. In 2 is the chassis 2 reproduced in detail. Central part of the chassis is the bottom 10 the seat 3 , Related to this are the two side panels 8th , which are each made of a stable metal plate.

The child seat 1 is not mounted in a vehicle in the direction of travel - ie in the same direction as the driver's seat but contrary to the same, so that a child sitting therein looks backwards.

For such an assembly is on the insides of the two side panels 11 of the chassis 2 one hollow profile each 12 fixed, for example., Welded, in such a way that it extends parallel to the direction of travel and on the backrest 4 opposite leading edge 13 the seat 3 survives. The hollow profiles 12 each have a square or rectangular cross-section. In each of the two hollow profiles 12 is in each case a second profile or inner profile 14 recorded, and telescopically displaced. Both the hollow profile 12 as well as the inner profile 14 each have holes 15 on, which at certain displacement positions of the two nested profiles 12 . 14 can bring in a common line of flight, so od by means of a cross-splint. Like. A locking of the set relative position between the two profiles 12 . 14 can be brought about. Instead of a splint can also do so within the inner profile 14 arranged to serve transversely displaceable elements which are urged by one or more integrated springs to the outside, as soon as in their area two aligned holes 15 are located.

At the free end of the thus adjustable in their overall length profiles 12 . 14 there is ever a locking head 16 for fixing to an anchoring point of the respective vehicle, which in turn is connected to the vehicle-mounted chassis and is accessible through a slot between the backrest and the seat cushion of the vehicle seat. Such an anchoring point has an approximately bow-shaped basic shape with a front transverse to the direction of travel central web, which of the locking head 16 can be encompassed. For this purpose, the locking head has 16 at its free end over a slot; this is similar to a groove that runs transversely to the direction of travel. The two side flanks of the slot each have inwardly, ie projections facing each other, which hook behind the central web of an anchoring tab and thereby form a positive connection. To close and release this connection, at least one of these hook nose-shaped projections can be moved out of the region of the slot, for example by manual actuation against the restoring force of a spring.

Is thus a determination of the child seat 1 takes place at the anchoring points of a vehicle, so the child seat can 1 neither move in the direction of travel nor across it more.

Although also the bottoms 9 the side parts 8th get up on the seat cushion of the vehicle seat, would still be a movement of the child seat 1 in the vertical direction still possible, with the two, lying in a direction transverse to the direction of flight aligned locking heads 16 form a kind of axle to the then still a tilting of the child seat 1 possible - either upwards, leaving the backrest 4 of the child seat 1 the backrest of the car seat approaches, or in opposite directions, with the child seat 1 at least temporarily pressed into the seat cushion of the vehicle seat.

To further restrict this possibility of movement, the two side parts 8th of the chassis 2 below the bottom 10 the seat 3 through several transverse elements 17 . 18 . 19 connected with each other.

One of these elements is as a pivot axis 17 formed, is located near the free front edge 13 the seat 3 and is designed as a tube with about its longitudinal axis rotationally symmetrical cross-section. Its two ends are each on one of two in a common flight, facing each other stub axles on the insides 11 the two side parts 8th plugged, leaving the tube 17 can perform a rotation about its longitudinal axis.

At the pivot axis 17 The two ends are one forward over the free leading edge 13 the seat 3 also pointing distance bracket 20 set of approximately U-shaped basic shape, in particular welded. The entire spacer bracket 20 is made of a single tube, preferably of metal, bent and therefore follows a relatively smooth curved course. Nevertheless, you can see two mirror-inverted thighs 21 and a central web interconnecting same 22 differ. The central pier 22 can be recognized by the fact that it is almost exactly transverse to the direction of travel or parallel to the pivot axis 17 runs; it is about the pivot axis 17 farthest area of the spacer bracket 20 , The ends of the center bar 22 are bent over at a gentle bend radius of more than 90 ° and are called thighs 21 continued. These approach each other initially to a small distance, for example. In the order of a few centimeters, for example. About 10 cm, to then beyond this approach range 23 - near the pivot axis 17 - to remove each other again. The two ends of the thighs 21 are at the pivot axis 17 fixed, in particular welded. These welded joints are about 15 to 25 cm apart. By this comparatively large distance receives the spacer bracket 20 a maximum stability, in particular torsional rigidity. How best to 1 can take, is the spacer bracket 20 not even, but at a distance of about 20 to 30 cm in front of the front edge 13 the seat 3 of the child seat 1 bent upwards, and indeed by an entire angle in the order of about 90 °, preferably slightly less than 90 °, for example. About 70 °. Also this vertical bending area 24 the two thighs 21 follows a relatively gentle course. The approach area 23 the two thighs 21 is about the vertical bending range 24 and serves the purpose of making room for the feet of a child.

Due to the rotatability of the swivel axis 17 around its longitudinal axis is the spacer bracket 20 vierschwenkbar. Due to the non-rotatable welded connection between spacer bracket 20 and pivot axis 17 transfers the respective Pivoting position of the spacer bracket 20 as a rotation angle on the pivot axis 17 ,

At this is within the vertical median plane of the child seat 1 an adjusting lever 25 fixed, the distance bracket 20 , In particular its lower, horizontal portion near the pivot axis 17 approximately diametrically opposite. The adjusting lever 25 is formed as a hollow profile of elongated cross-section with a longer extension in an approximately vertical direction. For connection to the swivel axis 17 are the two flat sides of the lever 25 pierced in a common flight to make room to pass the pivot axis 17 , These two elements 17 . 25 are then connected by welds. The adjusting lever 25 forms together with the spacer bracket 20 a double-armed lever and therefore determined with its angular position and the inclination angle of the spacer bracket 20 opposite the footprint 19 of the child seat 1 ; he can therefore to adjust the distance bracket 20 be used.

Because the length of the adjustment lever 25 about the depth of the child seat 1 or from its seat 3 corresponds, lies the free end 26 of the adjusting lever 25 under or behind the backrest 4 , as the 4 and 5 reveal. Near this free end 26 are the two flat sides of the adjusting lever 25 pierced again and through a transverse pin inserted 27 connected with each other. Within the designed as a hollow profile adjusting lever 25 serves the cross pin 27 as an abutment for a to the longitudinal axis of the adjusting lever 25 parallel compression spring attached to it with its tube end 26 abgewandten end face supports, while their the pipe end 26 facing end face in the adjusting lever 25 recorded block 28 supports, for example, can be made of plastic and with its circumference to the inner cross section of the adjusting lever 25 adapted to be slidably but non-rotatably guided therein. This block 28 is provided with a transverse bore, in which a transverse pin is pressed, which is longer than the width of the adjusting lever 25 so he ends with both his ends 29 by one each in the longitudinal direction of the adjusting lever 25 extending slot on both side surfaces of the adjusting lever 25 protrudes. Through these two slots and the pin ends engaging in them 29 is the displacement area of the block 28 limited. While the internal spring strives to block 28 from the back, open end 26 of the adjusting lever 25 This can be pushed out by manual pressure on the rear face 30 of the block 28 deeper into the lever 25 be pressed into it.

The back end 26 of the adjusting lever 25 protrudes between the two cross struts 18 . 19 of the chassis 2 of the child seat 1 through, as both cross struts 18 . 19 approximately vertically below the backrest 4 lie, the upper cross strut 18 near the bottom 10 the seat 3 the lower cross strut, on the other hand, just above the lower ground contact areas 9 the side parts 8th ,

These two crossbars 18 . 19 are on both sides of the lever 25 by one each of two flat or even metal strips 31 connected with each other. These two metal strips 31 run in a small mutual distance, which is only slightly larger than the width of the adjusting lever 25 , and their bases are parallel to each other. They are at the two cross struts 18 . 19 Preferably welded butt and thus together form an approximately vertically running slot for the lever 25 , This therefore has only so much freedom in the lateral direction that it can be adjusted without friction in accordance with a pivoting about the pivot axis 17 , This pivoting movement is limited in the vertical direction by the two transverse struts 18 . 19 ,

The two metal strips 31 extend between the two cross struts 18 . 19 with their longitudinal axes almost vertical. They are congruent cut and have at their the pivot axis 17 facing edge of a toothed area 32 on. The teeth are about the same size and have distances which are equal to or greater than the diameter of the ends 29 of the cross pin in the block 28 ; the recesses between each two adjacent teeth each have at their base a radius of curvature, which is about the radius of the ends 29 of the cross pin in the block 28 matches, so these ends 29 in free from external forces state under the influence of the internal compression spring, which is located on the cross pin 27 supported, to the rear in two mutually aligned recesses of the toothing 32 be pressed. By the mutually facing flanks of the teeth adjacent to this recess is any vertical movement of the adjusting lever 25 and thus also of the rigidly connected thereto via the pivot axis spacer bracket 20 inhibited - the spacer bracket 20 remains in the thus set pivot position.

To the spacer bracket 20 To adjust, a person must first by pressing on the free end face 30 of the block 28 the lateral extensions 29 of the adjusting lever 25 namely the ends 29 of the transverse pin received in the block, from the recesses between the teeth of the toothing section 32 lift out. Once this is done, the lever between its two end stops 18 . 19 be adjusted. For this purpose, the person serves a short, transversely to the lever extending handlebar 33 in one at the top of the adjusting lever 25 near its free end 26 welded eye 34 is fixed. Is the desired pivot position of the spacer bracket 20 reached, the pressure on the front side 30 of the block 28 finished and the internal spring pushes it out again, with the lateral extensions 29 again in mesh with the gearing 32 reach.

During the distance bracket 20 serves to a swinging up the child seat 1 around the latching heads latched to the anchoring points of the vehicle chassis 16 To avoid, they are unable, with each braking process of the vehicle a pitching motion of the child seat 1 to avoid to the front. Such a movement, however, acts as a footrest 35 opposite. This is designed as an elongated element, which on the lower cross member 19 between the metal strips 31 is stored so that it is around this crossbar 19 pivoted, in particular, can be folded in and out. In unfolded position prevents an extension 36 on the footrest 35 In this condition, at the toothless edge of the metal strip 31 gets to the plant that the footrest 35 can be swung further than in the approximately vertical, with the backrest 4 of the child seat 1 approximately aligned position according to the 4 and 5 ,

To adapt to vehicle seats with different height is the footrest 35 telescopically extendable. The outer tube has a series of holes 37 on, through which a screw 38 is hindurchsteckbar, which is screwed into a threaded bore of the inner tube, if this threaded bore with a bore 37 flees. With this screw 38 the two telescopic tubes are locked against each other, and thereby becomes the set length of the footrest 35 fixed. At the bottom has the footrest 35 over a foot 39 in the form of a short, fixed to the inner tube rod with transverse to the direction orientation. This foot 39 distributes possibly acting forces over a large surface area and thereby reduces the pressure load at the bottom of the vehicle.
