Description
Technical field
The present invention relates to a kind of seat belt system that is used for vehicle.。
Background technology
Current, the seat safety belt apparatus on the seat is widely used.When unexpected generations such as collision, utilize the seat belt restraint occupant to stop the occupant to fly out from seat, can play protective effect to the occupant.
Various types of seat safety belt apparatus are arranged, for example limit occupant's the shoulder and the shoulder hamess of chest exercise, the pelvic restraint of restriction occupant waist movement.Using the most generally, is the three-point seat belt device, and this device has a soft band, and an end of this soft band is fixed on the car body, and the other end is wound on the Webbing retractor that is fixed in car body after the belt guide guiding.On soft being with, be supported with tongue piece slidably.On car body or seat, be fixed with bracelet.During occupant's wear safety belt, tongue piece is inserted bracelet and locking.Soft band tightens up under the effect of taking-up device, is bearing on occupant's the health.At this moment, tongue piece is divided into two sections with soft band, and the soft band between belt guide and the tongue piece is inclined cross the occupant above the waist, and restriction occupant's the shoulder and the motion of chest are called shoulder hamess; Be fixed on a end and the soft band between the tongue piece on the car body across the motion of occupant's pelvis restriction occupant waist, be called pelvic restraint.
When unexpected generations such as collision, the urgent lockout mechanism action of winding up apparatus for safety belt stops soft band to be pulled out, and the restriction occupant forwards moves, thus the protection occupant safety.Particularly, some winding up apparatus for safety belt or bracelet etc. are provided with pre-tensioning device, and during unexpected the generation, the lax of soft band eliminated in pre-tensioning device work and strain soft band, further improved the confining guard effect to the occupant.
Yet when the occupant of children or stature slight of stature took on the seat, it was inapplicable to be found to be adult's design-calculated seat belt apparatus.Be inclined cross the shoulder hamess of adult's shoulder and chest according to adult's stature design-calculated, can cross children's head, even the children's that possibly fasten neck.If children directly wear adult's safety strap inadequately, will be very dangerous when unexpected generations such as collision.
At present, the comparison valid approach that overcomes the above problems is to adopt children to increase cushion, or regulate the height of shoulder hamess.Children increase the problem that cushion can bring ease of use.The safety strap height adjustment has many solutions; For example: application number 200580038606 disclosed " safety belt height adjuster "; Application number 200680018377 disclosed " height adjuster with return spring ", application number 200810127445 disclosed " balladeur train that is used for the height adjuster of belt system ".These schemes generally need for example be installed slide rail on the vehicle B post in body construction, complex structure, and cost is high.
Also have some trials, hope directly to draw shoulder hamess, make it depart from straight line path between belt guide and the tongue piece, thereby cross over children's shoulder and chest with suitable angle with an auxiliary soft band.The representative of these trials; Application number 97211037 disclosed " being arranged at the auxiliary security belting that the child on the safety strap uses " for example; Application number 200420095152 disclosed " children ride special-purpose auxiliary security band ", application number 201020019669 disclosed " a kind of children use the adjustment height safety strap ".More than attempt having a common constructional feature, subband all be " extension " on shoulder hamess, the joint of subband and shoulder hamess can be free to slide along shoulder hamess.This constructional feature makes subband very unreliable to the position constraint of shoulder hamess; When accident takes place; The huge tension force that shoulder hamess receives slides the junction surface of subband and shoulder hamess; Make shoulder hamess allow the more amount of moving forward, thereby can not play the effect of actv. confining guard child passenger.More dangerous is that the slip at junction surface may cause shoulder hamess to move up, thereby children's neck is damaged.Simultaneously, the stressed position of shoulder hamess concentrates on the lateral edges of soft band, causes the damage of soft band easily, causes the inefficacy of safety strap.
Summary of the invention
The object of the present invention is to provide a kind of safety belt for car seat system that is applicable to child passenger, this system can limit the height of the last obligatory point of shoulder hamess.
Technical scheme of the present invention is:
A kind of restraint buckles that is used to constitute seat belt system; Said seat belt system comprises and contains one section seatbelt that is inclined cross occupant's shoulder hamess above the waist; And auxiliary restraint strap, an end of auxiliary restraint strap is connected with an attachment point connecting device, and is connected with car body or seat through the attachment point connecting device; Be connected with a said restraint buckles on the other end of auxiliary restraint strap; Said restraint buckles combines with shoulder hamess and not locking slidably separably, it is characterized in that
Said restraint buckles comprises buckle main body and soft band pull bar; Buckle main body comprises a passage that inserts or shift out after supplying soft band to amount to; This passage comprises roof, diapire, left side wall, right side wall, and the front end of buckle main body has the insertion port of this passage, has a band connecting portion in the rear end; The both sides of said buckle main body are formed with a pair of pull bar supporting structure; When soft band and restraint buckles are in when inserting latched position, soft band pull bar runs through soft band to be amounted to the crack that the back forms and is horizontally placed on buckle main body, and the two ends of soft band pull bar are supported by the pull bar supporting structure that the buckle main body both sides form.
Another kind of technical scheme of the present invention is: a kind of restraint buckles that is used to constitute seat belt system; Said seat belt system comprises and contains one section seatbelt that is inclined cross occupant's shoulder hamess above the waist; And auxiliary restraint strap, an end of auxiliary restraint strap is connected with an attachment point connecting device, and is connected with car body or seat through the attachment point connecting device; Be connected with a said restraint buckles on the other end of auxiliary restraint strap; Said restraint buckles combines with shoulder hamess and not locking slidably separably, it is characterized in that
Said restraint buckles comprises buckle main body and soft band pull bar; Buckle main body comprises a passage that inserts or shift out after supplying soft band to amount to; This passage comprises roof, diapire, left side wall, right side wall, and the front end of buckle main body has the insertion port of this passage, has a band connecting portion in the rear end; Said buckle main body has horizontal soft band supporting structure; When soft band and restraint buckles are in when inserting latched position, soft band pull bar runs through soft band to be amounted to the crack that the back forms and is horizontally placed on buckle main body, and soft band supporting structure lateral support is on the zone face of soft band.
Realize emphasis of the present invention, be the restraint buckles that a kind of function is special.This functor is used to realize the locking to auxiliary restraint strap and shoulder hamess junction surface, thereby the engage position of auxiliary restraint strap of qualification and shoulder hamess makes auxiliary restraint strap and shoulder hamess form stable protection framework.
Use when of the present invention, insert restraint buckles after shoulder hamess is amounted to from the top down, held by soft band pull bar in the buckle in main body.The restrained bracelet of shoulder hamess is separated into two sections, and one section is inclined cross occupant's shoulder and chest extends downward tongue piece, and one section extends upward to belt guide.One section shoulder hamess upwards upwards draws under the effect of taking-up device, and auxiliary restraint strap is the tractive restraint buckles from the below, and the restriction bracelet moves up.
The restraint buckles main body can have a pair of pull bar supporting structure that is arranged on its both sides, and when soft band insertion restraint buckles, the soft band pull bar that is passed therebetween the termination of amounting to of soft band is held.The two ends of soft band pull bar are bearing on the pull bar supporting structure of buckle main body both sides formation un-rotatably.Turns back around soft band pull bar in the soft band buckle in main body, and at restraint buckles top port place respectively up and down two directions turn back.Because auxiliary restraint strap has limited restraint buckles and has moved up; The pulling force that Webbing retractor produced makes soft band produce tension force; Respectively upwards and under the combined action of the pulling force of two sections soft bands that extend below and restraint strap, soft band imposes on the position that soft band pull bar and port etc. contact with soft band with pressure.Consequent friction force stops the slide relative of soft band and restraint buckles.
The restraint buckles main body can have soft band supporting structure; This soft band supporting structure is between the bearing position that inserts access port and soft band pull bar; Lateral support is on the zone face of soft band; Make the straight line path between the bearing position of walking around insertion port that two sections soft bands that soft band pull bar turns back depart to be limited tension force and soft band pull bar, produce bending and superimposed.Bending part further increases soft with suffered friction drag because of soft band tension force makes outer soft band to the soft band application stress of internal layer.Friction force increases with the increase of tension force, so even when bumping accident, total softly also can stop the slide relative of shoulder hamess and restraint buckles with suffered friction force, with shoulder hamess and restraint buckles locking.
Soft band supporting structure can be formed by the lagging dege of roof or diapire, perhaps sets up part.Under the situation that does not have the pull bar supporting structure, a plurality of horizontal soft band supporting structures also can stop shifting out of soft band.A moved cross beam for example is set, after soft band has passed the insertion passage and inserted soft band pull bar, moves moved cross beam, make the thickness that inserts passage be retracted to thickness, just can stop shifting out of soft band pull bar less than soft band pull bar.
When restraint buckles combined with shoulder hamess, shoulder hamess was producing a bending with the restraint buckles junction.Therefore, the port shape of restraint buckles is configured to have a gradient to adapt to the bearing of trend of shoulder hamess.
In order to prevent that soft band pull bar from rolling under the unbalanced tension of two sections soft bands, the for example anti-structure of rolling of lug can be set on the buckle main body.
Auxiliary restraint strap is the band connecting portion with the position that bracelet is connected with the attachment point connecting device.The band connecting portion generally is made up of the crossbeam of the soft band of supporting.One in the band connecting portion at restraint strap two ends can include the structure of regulating soft strip length; A kind of selectable soft strip length adjustment structure comprises the crossbeam of two soft bands of supporting; Form the soft strip length adjustment structure of so-called order font; Make that the lock height of restraint buckles is adjustable, thereby regulate the last obligatory point height of shoulder hamess.
The fit of soft band pull bar and soft band has two kinds.A kind of mode is, after soft band inserts bracelet, soft band pull bar inserted soft band from the side of bracelet and amounts to the crack that the back forms, then on the pull bar supporting structure with the two supports buckle in main body both sides of soft band pull bar.The second way is, extends a guide structure in the outer end of soft band pull bar, holds soft band with soft band pull bar earlier, utilizes guide structure pull bar and soft band together to be inserted the insertion port of bracelet then.The hole that can extend an opening or remain silent from the pull bar outer end is used for pull bar is bearing in safety strap slidably.Simultaneously a traction handle can be set above that further, this traction handle can be connected with pull bar rotationally, or adopts the flexible material manufacturing.
Restraint buckles main body of the present invention and crossbeam can adopt metal sheet to process.When adopting metal sheet to add man-hour, be to increase the intensity of inserting passage roof and diapire, can press horizontal recessed above that, or in the port crimping.
For increasing the area of contact of soft band and port, reduce soft belt wear, can adopt resin coated metal plate outside.Can the port surface be arranged to have the circular shape of arc-shaped transition.
The present invention also can adopt die cast.
During embodiment of the present invention, auxiliary restraint strap and shoulder hamess bonded assembly optimum position are near occupant's shoulder top.
Current, the backrest of the back seat of most of manned vehicle and the junction surface of cushion all are provided with the attachment point that is used to install the child safety device, and the lower end of auxiliary restraint strap can be connected on this attachment point.
The preferred version of embodiment of the present invention is; The lower end of auxiliary restraint strap is connected on the attachment point that is arranged on back of seat and cushion junction surface through the attachment point connecting device; And along back of seat from the occupant behind near the position occupant's shoulder top extend, combine with shoulder hamess through restraint buckles in this position or separate.
Adopt above scheme; Can bring other benefit to be: auxiliary restraint strap is in occupant's behind; Shoulder hamess is inclined cross the occupant front, and in fact two soft bands have wrapped occupant's shoulder, when the occupant moves on the seat by a small margin; Soft band will be followed its head movement, reduce the probability of soft band slippage.
The present invention can make full use of the defencive function of existing belt system.The pre-tensioning device that is arranged on the Webbing retractor is effective equally to this seat belt system that has added auxiliary restraint strap.When bumping accident, even the occupant has on the seat by a small margin and to move that soft band has been produced is lax, pre-tensioning device also can make auxiliary restraint strap tighten simultaneously with shoulder hamess, protects thereby the occupant provided to greatest extent.

The specific embodiment
Below in conjunction with the description of drawings specific embodiment.
Fig. 1 and Fig. 2 have represented a kind of embodiment of seat belt system of the present invention.
In the present embodiment, child passenger wear the adult with three-point seat belt in, used an auxiliary restraint strap to adjust the height of obligatory point on the shoulder hamess.
Three-point seat belt shown in the figure (1), one of which end are fixed on the attachment point (6) of car body, and the other end is wound on the Webbing retractor (7) that is fixed in car body after belt guide (8) guiding.On soft band (1), be supported with tongue piece (9) slidably.On car body, be fixed with bracelet (10).During occupant's wear safety belt (1), tongue piece (9) is inserted bracelet (10) and locking.Soft band (1) tightens up under the effect of taking-up device (7), is bearing on occupant's the health.At this moment, tongue piece (9) is divided into two sections with soft band (1), and the soft band between belt guide (8) and the tongue piece (9) is called shoulder hamess (1a); The end (6) and the soft band between the tongue piece (9) that are fixed on the car body are called pelvic restraint (1b).
Because this three-point seat belt is to be adult's design-calculated, so children are when directly wearing, and shoulder hamess can not correctly be inclined cross its shoulder and chest, but its neck that fastens can bring danger.Yet through the help of an auxiliary restraint strap, child passenger can be pulled down near its position, shoulder top with shoulder hamess easily, makes shoulder hamess be inclined cross it above the waist with correct position and angle.
The lower end of auxiliary restraint strap provided by the present invention (3) is connected on the attachment point (5) that is arranged on back of seat and cushion junction surface through an attachment point connecting device (4).The band connecting portion of attachment point connecting device (4) has a soft strip length adjustment structure (20) (a kind of alternative soft strip length adjustment structure is seen Figure 13); Therefore the length that can regulate auxiliary restraint strap (3); Make auxiliary restraint strap (3) extend near position, occupant's shoulder top behind along back of seat from the occupant, combine with shoulder hamess (1a) through restraint buckles (2) in this position.Thus shoulder hamess (1a) is divided into two sections; Soft band between restraint buckles (2) and the belt guide (8) is the upper semisection (1aa) of shoulder hamess, and the soft band between restraint buckles (2) and the tongue piece (9) is the lower semisection (1ab) of shoulder hamess.
Because being adjusted to the binding site that makes restraint buckles (2) and shoulder hamess (1a), the length of auxiliary restraint strap (3) just in time is near occupant's shoulder top; Therefore; The suitable adjustment shoulder hamess (1a) and the binding site of restraint buckles (2); Promptly suitably adjust the length of the lower semisection (1ab) of safety strap, just can make the lower semisection (1ab) of shoulder hamess wear and bring the excellent protection effect with correct position and angle.
When the unexpected generation of collision, the lower semisection (1ab) that is bearing in children's safety strap on one's body will receive huge impact power, and pass to each section and auxiliary restraint strap (3) of safety strap (1).At this moment, restraint buckles (2) be if can not will make the lax and forfeiture protection effect of whole belt system with shoulder hamess (1a) locking but along its slip, even causes and make the fasten danger of occupant's neck of shoulder hamess (1a).
The present invention addresses the above problem through following designed constraints bracelet.
Fig. 3 is a kind of restraint buckles that the present invention proposes, i.e. the structural representation of restraint buckles ().Its buckle main body schematic rear view is seen Fig. 4.
This restraint buckles (2) comprises buckle main body (11) and soft band pull bar (12).The two ends bending of soft band pull bar (12), the distance between the two bending heads is a bit larger tham the width of buckle main body (11).Buckle main body (11) comprises a passage (11A) that inserts or shift out after supplying soft band to amount to; This passage (11A) is by roof (13); Diapire (14), pair of sidewalls comprises that left side wall, right side wall (15) surround and form; The front end of buckle main body (11) has the insertion port of this passage, has a band connecting portion (11B) in the rear end.The and arranged on left and right sides wall (15) of buckle main body (11) extends back, and the upper limb of two side forms a pair of pull bar supporting structure (16), and the lagging dege at roof (13) has formed a horizontal soft band supporting structure (17) simultaneously.Continue to extend back and close up in two side (15), form one with roof crossbeam (21) at grade, as the band connecting portion (11B) of buckle main body (11).What form pull bar supporting structure (16) also can be the lower edge of two side (15), and this depends on that soft band pull bar (12) is to be assemblied in from above or from below on the buckle main body (11).Because shoulder hamess (1a) is producing a bending with restraint buckles (2) junction; Therefore the front end (13A) of the roof of buckle main body (11) has an angle of inclination with the insertion channel direction, and shoulder hamess was to the angle that extends below when this angle roughly was adapted to occupant's wear safety belt.
When soft band and restraint buckles (2) are in when inserting latched position; Soft band pull bar (12) runs through soft band to be amounted to the crack that the back forms soft band is held; Across buckle main body (11); The bending head at two ends is stuck in the outside of buckle main body (11) two side, limits the horizontal position of soft band pull bar (12) with this.At this moment; Soft band receives taking-up device (7) and applies outside pulling force above that; Being bearing in soft band pull bar (12) on the pull bar supporting structure (16) then passes soft band and amounts to head soft band is held; Simultaneously, laterally be pressed on the soft band zone face, stop soft band from buckle main body (11), to shift out jointly as the lagging dege of the roof (13) of soft band supporting structure (17).
Soft band supporting structure (17) is positioned between the bearing position that inserts access port and soft band pull bar (12); Lateral support is on the zone face of soft band; Make and walk around insertion port that two sections soft bands that soft band pull bar (12) turns back depart to be limited tension force and the straight line path between the soft band pull bar (12), produce bending and superimposed.Bending part further increases soft with suffered friction drag because of soft band tension force makes outer soft band to the soft band application stress of internal layer.Friction drag increases with the increase of tension force; Even so when bumping accident; Softly also can stop the slide relative of shoulder hamess (1a) and restraint buckles (2), with shoulder hamess (1a) and restraint buckles (2) locking with suffered total friction force.
Fig. 8 is second kind of restraint buckles that the present invention proposes, the i.e. structural representation of restraint buckles (two).Its buckle main body schematic rear view is seen Fig. 9.
Be that with the different place of restraint buckles () hole of remaining silent is extended at the two ends of the soft band pull bar (12) of this restraint buckles (2), be used for soft band pull bar (12) is bearing in safety strap slidably.Further be provided with a traction handle (19) above that, consider that from assembling back occupant traveling comfort this traction handle (19) can be connected with soft band pull bar (12) rotationally, or adopt flexible material to make.Like this, can pass through the soft band of traction handle (19) guiding and insert buckle main body (11).
Because soft band pull bar (12) passes, therefore insert the width of width of channel greater than soft band from insert passage.In order to support soft band pull bar (12), the pull bar supporting structure (16) of buckle main body (11) is that the Outboard Sections by roof or diapire extends back and forms.The width of the groove that forms between the two sides of support structures (16) is slightly larger than soft bandwidth less than the length of soft band pull bar (12), makes when soft band pull bar (12) supports above that soft band can be pulled out from this groove.Soft band supporting structure (17) is formed by the trailing edge of roof (13) between the two sides of support structures (16) or diapire (14).Crossbeam (21) as band connecting portion (11B) can be extended to form by the tail end of roof (13) or diapire (14).
Owing to insert the width of width of channel greater than soft band, therefore soft band possibly produce lateral excursion in inserting passage.In order to limit the adverse effect that this skew brings, the groove with soft bandwidth coupling can be set on the internal face of roof (13) and diapire (14) or front end.
(1) compares with restraint buckles, though there is above difference on the CONSTRUCTED SPECIFICATION, this restraint buckles can realize and the identical effect of restraint buckles (), is about to shoulder hamess (1a) and restraint buckles (2) locking.
More than two kinds of restraint buckles to wear operating mode different.
The operating mode of wearing of restraint buckles () is: after soft band inserts buckle main body (11), soft band pull bar (12) is inserted soft band from the side of buckle main body (11) and amount to the crack that the back forms; Then the bending head at soft band pull bar (12) two ends is stuck in the outside of buckle main body (11) two side, soft band pull bar (12) is bearing on the pull bar supporting structure (16).
Fig. 5, Fig. 6, Fig. 7 are seen in the operating process of wearing of restraint buckles ().
The operating mode of wearing of restraint buckles (two) is: directly utilize traction handle (19) to drive the insertion passage that the soft band of soft band pull bar (12) guiding gets into buckle main body (11), up to traction handle (19) and soft band pull bar (12) are pulled out from insert passage downwards.With moving on the soft band pull bar (12) and retreating, soft band pull bar (12) is bearing on the pull bar supporting structure (16) then.
Figure 10, Figure 11, Figure 12 are seen in the operating process of wearing of restraint buckles (two).
