Abstract

(57) [Summary] [Purpose] Even when the child seat is fixed to the passenger seat while facing backward, the visibility of the passenger seated in the driver's seat with respect to the door mirror on the passenger seat side can be ensured and the child seat can be secured. To obtain a child seat that can be tilted at an optimum angle for a child regardless of whether the is used in the forward or backward direction. [Structure] When only the child seat body 14 is fixed to the seat cushion 16A in a rearward facing state, the bulging portion 60 and the protruding portion 62 for the reclining mechanism are in contact with the seating surface, whereby the vehicle vertical direction is increased. The tilt angle θ1 is set to about 35 degrees (reclining standard angle). Therefore, since the total height is reduced by not using the base, the visibility of the door mirror is improved, and the tilt angle is optimal for children regardless of whether the base mirror is forward or backward.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a child seat attached to a seat cushion of a vehicle seat.

[0002]

[Prior art]

 Traditionally, children's seats have been used to seat a child in the passenger seat or rear seat of a vehicle. There are various types of children's seats, and among them, there is one in which a portion corresponding to the body of the children's seat and a portion corresponding to the base are integrally configured. This type of child seat is fixed to the seat cushion of the vehicle seat with the child seat facing backwards so that the infant faces the rear of the vehicle when the infant is 6 months old to under 1 year old. However, when an infant younger than one to four years old is seated, the child seat is fixed to the seat cushion of the vehicle seat with the child seat facing forward so that the infant faces the front of the vehicle. In other words, by changing the orientation of the child seat to the front or back, it is designed to be used for infants or infants.

[0003]

[Problems to be solved by the device]

 However, with this structure, when the child seat is fixed to the seat cushion of the passenger seat in the rearward facing state, the height of the child seat increases because the base portion cannot be separated from the child seat body. For this reason, there is a problem that it is difficult for an occupant seated in the driver's seat to see the passenger side door mirror.

Further, since there is a base portion, the tilt angle of the child seat with respect to the vehicle vertical direction when the child seat is fixed to the seat cushion in the rearward facing state is an optimum angle (with respect to the vehicle vertical direction). There is also a problem that it cannot be set to around 35 degrees). This problem can be solved by increasing the reclining angle in the case of a child seat equipped with a reclining mechanism, but this would require a design change to make the reclining angle wide. So it is a disadvantage.

In consideration of the above facts, the present invention can secure the visibility of the passenger side passenger's seat side door mirror even when the child seat is fixed to the passenger seat in a rearward facing state. At the same time, it is an object of the present invention to obtain a child seat that can be tilted at an optimum tilt angle for a child regardless of whether the child seat is used in the forward or backward direction.

[0006]

[Means for Solving the Problems]

 A child seat according to the present invention comprises a base fixed to a seat cushion of a vehicle seat, a child seat body detachably attached to the base, and a convex portion provided on the back side of the child seat body. A reclining mechanism for changing the tilt angle of the seat body for a child with respect to the vehicle up-down direction by moving the support means supported by the base along the guide means provided on the base. A first use state in which the seat body is attached to the base and is fixed to the seat cushion of the vehicle seat in a forward facing state, and a seat of the vehicle seat in a state in which only the child seat body is facing backward. A second use state in which the convex portion is in contact with a seat surface of the seat cushion. Te, tilt angle with respect to the vehicle vertical direction of the child seat body, is characterized in that it matches the predetermined angle is a standard tilt angle by the reclining mechanism in the first use state.

[0007]

[Action]

 According to the above configuration, when the child seat is used for infants, the child seat is in the first usage state. That is, the seat body of the child is fixed to the seat cushion of the vehicle seat with the seat body mounted on the base and facing forward. In the first usage state, the tilting angle of the child seat body with respect to the vehicle up-down direction can be changed by moving the supporting means in the reclining mechanism along the guide means. On the other hand, when the child seat is used for infants, the child seat is in the second usage state. That is, the base is not used and only the child seat body is fixed to the seat cushion of the vehicle seat with the seat facing backward.

Therefore, in the second use state, the total height of the child seat is the height of only the child seat main body, so that even if the child seat is fixed to the passenger seat, the occupant sitting in the driver's seat is on the passenger seat side. The door mirrors will not be hard to see.

Further, in the second use state, the convex portion supporting the support means comes into contact with the seat surface of the seat cushion, so that the tilt angle of the child seat body with respect to the vehicle vertical direction in the first use state. It matches the specified tilt angle, which is the standard tilt angle of the reclining mechanism. That is, the posture of the child in the seated state can be set to the optimum angle in both the first use state and the second use state.

Further, since the tilt angle of the child seat main body with respect to the vehicle vertical direction is set to a predetermined angle by using a part (projection) of the reclining mechanism, a component for determining the tilt angle is separately provided. There is no need, and the number of parts can be reduced and the structure can be simplified.

【Example】

 Hereinafter, the child seat 10 to which the present invention is applied will be described with reference to FIGS. 1 to 11. The child seat 10 is an infant seat (IRS) for carrying an infant aged 6 months to less than 1 year old, and a child seat for carrying an infant aged from 1 to 4 years old. (Abbreviated as CRS) can be used.

As shown in FIG. 1, the child seat 10 includes a base 12 and a child seat body 14 attached to the base 12. When the child seat 10 is used as a child seat, the child seat 10 is attached to the base 12. It is used with the seat body 14 attached (see Fig. 2; this is the first usage state in the present invention), and when used as an infant seat, the base 12 is not used for children. Only the seat body 14 is used (see FIG. 9; this state is the second state of use in the present invention). Hereinafter, the child seat body 14, the base 12, the reclining mechanism, and the attachment / detachment mechanism will be described in this order, and then the configuration when used as an infant seat will be described.

[Description of Child Seat Body 14] The child seat body 14 includes a curved shell 18 that matches the average posture of a seated child. The shell 18 is relatively rigid and made of resin, and the shell 18 serves as a skeleton member of the child seat body 14.

A relatively thick cushion pad made of urethane or the like and covered with a skin material is arranged on the lower surface of the shell 18. A relatively thin back pad formed of urethane or the like and covered with a skin material is arranged on the upper surface of the shell 18. As a result, the seat back and the seat cushion are integrally formed. Further, in the child seat body 14, side support support portions 18A are integrally formed on both sides of the lower portion of the shell 18. A webbing insertion hole 19 is formed in the side support support portion 18A, and side supports 20 for supporting both sides of the waist of the child are fitted therein.

A headrest 22 is provided at the upper end of the shell 18. The headrest 22 is provided so as to be slidable in the height direction of the shell 18 by a predetermined amount. When the headrest 22 slides, the headrest lower pad 24 integrally provided on the headrest 22 also slides.

A pair of child restraint belts 26 are inserted through the central portion of the headrest 22. The child restraint belt 26 is bifurcated at the middle portion in the longitudinal direction. The base end portion of the child restraint belt 26 is wound around an ELR type webbing retractor (not shown) disposed below the shell 18, and a tongue plate 28 is attached to the tip end of the bifurcated portion. Each is installed. These tongue plates 28 are engaged with a crotch buckle 30 provided upright near the front end of the seat cushion of the shell 18.

[Description of Base 12] On the other hand, as shown in FIG. 5, the base 12 is a base portion 12A which is a portion to be placed on the seat surface of the seat cushion 16A of the vehicle seat 16, and the base portion 12A. The standing portion 12B is erected from the rear end portion and pressed against the surface of the seatback 16B. Then, the base 12 is fixed by using the three-point webbing 32 of the vehicle seat 16 at a portion where the base portion 12A and the standing portion 12B meet. That is, after the shoulder side webbing 32A and the lap side webbing 32B are locked by the E-clip 34 and overlapped with each other, the shoulder side webbing 32A and the lap side webbing 32B are hung on the upper end surface of the base 12 as they are, and the tongue plate 36 is engaged with the buckle device 38. By doing so, the base 12 is fixed to the seat surface of the seat cushion 16A.

[Description of Reclining Mechanism and Attachment / Detachment Mechanism] The above-described child seat body 14 is configured to be tiltable with respect to the base 12 by a predetermined angle, and the reclining mechanism therefor will be described in detail below.

A pair of rail portions 40 are formed on both sides of the base 12 described above. The rail portion 40 is curved at a predetermined angle. The pair of rail portions 40 are generally constituted by a roller guide portion 42 and a rod guide portion 44.

The roller guide portion 42 is provided on the base 12 A side of the base 12. Each roller guide portion 42 is formed in a U-shaped cross section by the bottom surface of the base 12, an inner side surface, and a guide wall extending from the upper end of the inner side surface in a direction toward each other. As a result, the roller guide groove 42A is formed in the roller guide portion 42. A pair of rollers 64 of the child seat body 14 described later are rotatably fitted into these roller guide grooves 42A. The front end portion of the roller guide portion 42 is closed by a substantially arcuate wall 46 corresponding to the outer diameter of the roller 64.

On the other hand, the rod guide portion 44 is provided on the standing portion 12 B side of the base 12. As shown in FIG. 7, each rod guide portion 44 is a frame 52 in which an iron plate is bent in a U shape and is fixed to the upright portion 12B of the base 12 with bolts 48 and nuts 50, and is fitted into the frame 52. And a resin guide member 54. A rod guide groove 44A having a groove width slightly larger than the outer diameters of a pair of rods 66 of the child seat body 14 to be described later is formed in the middle portion of the guide member 54. Further, a plurality of rod fitting holes 56 and 57 are coaxially formed at predetermined intervals on the bottom surface of the rod guide groove 44A and the frame 52, respectively. The rod 66 is selectively fitted into any of the plurality of rod fitting holes 56 and 57. Further, the upper end portion of the rod guide portion 44 is expanded in diameter to form an open portion 58 (see FIGS. 4 and 5).

As shown in FIG. 6, a substantially rectangular bulging portion 60 is formed on the upper side of the back surface of the child seat body 14, and a protruding portion 62 is formed on the lower side thereof. ing . The projecting portion 62 has a trapezoidal cross section and is projected to a predetermined length. A pair of rollers 64 are axially supported by the protrusion 62, and are fitted in the roller guide groove 42A of the roller guide portion 42 described above so that the roller 64 can roll along the roller guide groove 42A. In addition, the bulging portion 60 has a rectangular cross section, and the protruding length thereof is also set to a predetermined length. A pair of rods 66 are coaxially projected at the lower corners of the bulging portion 60, and are selectively fitted into the rod fitting holes 56 and 57 of the rod guide groove 44A of the rod proposal interior 44 described above. It is possible.

The pair of rods 66 described above causes the inside of the bulging portion 60 to be pulled by pulling the operation knob 70 (see FIG. 1) arranged in the opening portion 68 provided at the front end portion of the child seat body 14. It is configured so as to be retracted by a predetermined amount into the rod fitting hole 56 and will be briefly described below.

As shown in FIGS. 7 and 8, an L-shaped lever 72 is connected to each rod 66. The pair of levers 72 are pivotally supported by a pivot pin 74 at their bent portions. Further, long holes 76 are formed at one end of the lever 72, and a pulling pin 78 is inserted into these long holes 76. The tow pin 78 penetrates the rod 66 in the direction perpendicular to the axis. As a result, the rod 66 and the lever 72 are connected. A compression coil spring 83 is interposed between the pair of traction pins 78. Therefore, the compression coil spring 83 presses and urges the pair of rods 66 in the direction in which they are separated from each other (that is, in the direction in which the pair of rods 66 are fitted into the rod fitting holes 56, 57).

Further, a long hole 80 is formed at the other end of the lever 72, and a connecting pin 82 is loosely fitted in a state where these long holes 80 are overlapped. A wire 86 of a cable 84 held by the clamp 83 is wound between the levers 72 around the outer periphery of the connecting pin 82. As a result, the pair of levers 72 and the wire 86 are connected. In addition, one end of the cable 84 is connected to the operation knob 70. Therefore, when the operation knob 70 is pulled, the wire 86 of the cable 84 is pulled in the direction of arrow A in FIG. 8, and the pair of levers 72 is rotated in the direction of arrow B in FIG. As a result, the pulling pin 78 pulls the rods 66 in directions toward each other against the biasing force of the compression coil spring 83.

Further, a cutout portion 88 is formed at each of the connecting portions between the pair of roller guide portions 42 and the rod guide portion 44 described above. The notch width of each notch 88 is larger than the outer diameter of the roller 64. Therefore, by positioning the roller 64 in the cutout portion 88, the roller 64 can be separated from the roller guide portion 42.

An arcuate retreat groove 90 is formed in the pair of rod guide portions 44 in the vicinity of the ends on the notch 88 side. The groove width of these retracting grooves 90 is slightly larger than the outer diameter of the rod 66. Therefore, by positioning the rod 66 in the retreat groove 90, the rod 66 can be separated from the rod guide portion 44.

When the pair of rollers 64 are located at the front ends of the roller guide grooves 42A, the pair of rods 66 are located at the base ends of the retracting grooves 90, and the pair of rollers 64 are notched. The length between the roller 64 and the rod 66, the length of the roller guide portion 42, and the length of the rod guide portion 44 are set so that the pair of rods 66 are positioned at the open portion 58 when they are positioned at 88. There is.

[Usage State as Infant Seat] When the above-described child seat 10 is used as an infant seat, only the child seat body 14 is used without using the base 12. That is, as shown in FIG. 9, the child seat body 14 is mounted and fixed on the seat cushion 16A of the vehicle seat 16 in a state in which the occupant seated on the seat body 14 faces rearward of the vehicle. At this time, the webbing 32 is inserted into the webbing insertion hole 19 provided in the side support supporting portion 18A of the shell 18, and the tongue plate 36 is engaged with the buckle device 38, so that the child seat body 14 is fixed in the rearward facing state. It is supposed to be done.

Here, as shown in FIG. 10, when the child seat body 14 is placed on the seat cushion 16 A, the tip end of the projection 62 supporting the pair of rollers 64 is seat cushion. The lower corners of the lower ends of the bulging portions 60 that support the pair of rods 66 come into contact with the rear end inclined surface of the seat cushion 16A, and come into contact with the front end inclined surface of the seat cushion 16A. As a result, the tilt angle θ1 of the child seat body 14 with respect to the vehicle up and down direction is approximately 35 degrees. This tilt angle θ1 = 35 degrees is an optimum angle for the posture of children including infants.

On the other hand, although FIG. 11 shows a side view of the use state as a child seat, even in the use state as the child seat, the tilt angle θ2 of the child seat body 14 with respect to the vehicle vertical direction is also shown. Is approximately 35 degrees. To be precise, when using it as a child seat, the reclining mechanism can be used to change the tilt angle within a predetermined range according to the infant's physique, so reclining in the middle between the highest position and the lowest position. This means that the angle (standard tilt angle in the present invention) is approximately 35 degrees.

The operation of this embodiment will be described below. First, a case where the child seat 10 is used as a child seat will be described.

First, the operation of mounting the child seat 10 on the seat cushion 16A of the vehicle seat 16 is performed in the following procedure.

When the child seat body 14 is already attached to the base 12 and fixed to the seat cushion 16A, the child seat 10 is first placed on the seat surface of the seat cushion 16A. Next, it is confirmed whether or not the reclining position is set to the lowest position, and when it is set to the lowest position, the operation knob 70 is gripped and pulled. As a result, the pair of rods 66 are slightly retracted into the bulging portion 60, so that the engagement state between the pair of rods 66 and the rod fitting hole 56 of the frame 52 is released.

Next, as shown in FIG. 4, with the pair of rollers 64 located at the front end position (position of the wall 46) of the roller guide groove 42A as the center of rotation, the child seat body 14 is moved by the arrow C in FIG. It is rotated in the direction (hereinafter referred to as "tilt up"). As a result, the tip portions of the pair of rods 66 are separated from the rod guide portion 44 while passing through the retracting groove 90. In this state, the space above the base 12A of the base 12 is sufficiently secured.

Next, in this state, the base 12 is fixed to the seat surface of the seat cushion 16A using the adult webbing 32. That is, after the shoulder side webbing 32A and the lap side webbing 32B are overlapped with each other, they are locked using the E-clip 34 and then the upper end surface of the base 12 is bridged to engage the tongue plate 36 with the buckle device 38. Let As a result, the base 12 is securely fixed to the seat surface of the seat cushion 16A.

Next, the child seat body 14 in the tilted-up state is returned to its original state. When the operating knob 70 is released after the return, the pair of rods 66 are pressed by the biasing force of the compression coil spring 83 in the direction in which they are separated from each other, and are inserted into the predetermined rod insertion holes 56, 57. As described above, the operation of mounting the child seat 10 on the seat cushion 16A is completed.

In the above-mentioned operation of mounting the child's seat 10, only the base 12 is first fixed to the seat cushion 16A, and then the child's seat body 14 is mounted, regardless of the above procedure. It may also depend on the procedure.

Next, the reclining operation will be described. To change from a given reclining position to another reclining position, follow the procedure below.

First, the operation knob 70 is pulled to release the engagement state between the pair of rods 66 and the rod fitting hole 56. When the operation knob 70 is pulled, the pulling pin 78 is pulled in the direction of arrow A in FIG. 7 via the wire 86. Therefore, the pair of levers 72 are rotated in the direction of arrow B in FIG. 7, whereby the pair of rods 66 are pulled in a direction in which they approach each other against the biasing force of the compression coil spring 83. Therefore, the engagement state between the pair of rods 66 and the rod fitting hole 56 is released.

Then, the child seat body 14 is slid along the rail portion 40 to a desired position. More specifically, with the pair of rollers 64 fitted in the roller guide groove 42A of the roller guide portion 42, and with the pair of rods 66 fitted in the rod guide groove 44A of the rod guide portion 44. The child seat body 14 is slid.

Then, when the child seat body 14 is slid to a desired position, the operation knob 70 is released. As a result, the pair of rods 66 are pushed by the biasing force of the compression coil spring 83 in the directions in which they are separated from each other, and are fitted into the rod fitting holes 56 and 57. As a result, the reclining position of the child seat body 14 is changed to an optimal position according to the physique of the child.

As described above, after the reclining angle of the child seat body 14 is adjusted, the child is seated on the child seat body 14. Thereafter, the tongue plate 28 of the child restraint belt 26 is engaged with the crotch buckle 30. As a result, the child is restrained by the child restraint belt 26. In this state, when the vehicle suddenly decelerates, the load acting on the child restraint belt 26 due to the inertial movement of the child toward the vehicle front side is transmitted from the child seat body 14 to the frame 52 of the base 12, and It is transmitted to the vehicle body through the webbing 32 that fixes the base 12.

Next, an operation of separating the child seat body 14 from the base 12 will be described. Note that this operation is required, for example, when the vehicle is parked and the child seat body 14 is attached to a buggy car to carry an infant. The detaching operation will be described below, but there are two ways to detach.

The first method is as follows. First, the child seat body 14 is tilted up. That is, by pulling the operation knob 70, the engagement between the pair of rods 66 and the rod fitting holes 56 is released, and the child seat body 14 is slid along the rail portion 40 to the lowest position. Next, the child-use seat body 14 is rotated in the direction of arrow C in FIG. 4 with the pair of rollers 64 as the center of rotation. As a result, the rod 66 passes through the retreat groove 90 and separates from the rod guide groove 44A.

Next, while maintaining the tilt-up state, the child seat body 14 is slid rearward along the pair of roller guides 42. The sliding amount is set until the pair of rollers 64 located on the wall 46 is located at the cutout portion 88. Then, when the pair of rollers 64 reach the notch 88, the pair of rollers 64 is separated from the notch 88. As a result, the child seat body 14 is separated from the base 12.

The second method is as follows. First, the child seat body 14 is slid to the highest position by the above-described reclining operation. In this state, the pair of rods 66 are located in the open portion 58 and the pair of rollers 64 are located in the cutout portion 88. Therefore, as shown in FIG. 3, if the child seat body 14 is slightly lifted as it is, the child seat body 14 is disengaged from the pair of rail portions 40.

Next, a case where the child seat 10 is used as an infant seat will be described.

In this case, the base 12 is not used, and only the child seat body 14 is used. Then, as shown in FIG. 9, the child seat body 14 is fixed to the seat cushion 16A of the vehicle seat 16 in a state of facing backward so that the seated infant faces the rear of the vehicle. The fixing operation is performed by inserting the webbing 32 into the webbing insertion hole 19 provided in the side support supporting portion 18A of the shell 18 and engaging the tongue plate 36 with the buckle device 38.

Here, as shown in FIG. 9, in a state where the child seat body 14 as an infant seat is fixed to the seat cushion 16A of the passenger seat, the seat for the child is not used because the base 12 is not used. The overall height of the body 14 is reduced. Therefore, the visibility of the passenger seated in the driver's seat with respect to the passenger side door mirror 100 is secured.

Further, as shown in FIG. 10, in this state, the tilt angle θ1 of the child seat body 14 with respect to the vehicle up and down direction is about 35 degrees which is said to be the optimum angle for the posture of the child including the baby. . On the other hand, as shown in FIG. 11, even when the child seat 10 is fixed to the seat cushion 16A as a child seat, the tilt angle of the child seat body 14 with respect to the vehicle up-down direction is the same as in the infant seat. The degree θ2 is approximately 35 degrees. In other words, the posture of the seated child is at the optimum angle regardless of whether the infant seat or the child seat is used.

As described above, in the present embodiment, the child seat 10 is configured by the base 12 and the child seat body 14, and the child seat body 14 is configured to be attachable to and detachable from the base 12. When using as an infant seat, the child seat body 14 is used only without using the base 12, so even when the child seat body 14 is fixed to the front passenger seat in a rearward direction, The visibility of the passenger seated in the driver's seat with respect to the passenger side door mirror 100 can be secured.

Further, in the present embodiment, not only the standard tilt angle of the child seat body 14 with respect to the vehicle vertical direction in the use state as the child seat is set to the optimum angle θ2 (= approximately 35 degrees), but also the reclining mechanism is used. By making the bulging portion 60 and the protruding portion 62, which are a part of the seat, contact the seat surface of the seat cushion 16A, the tilt angle of the child seat body 14 with respect to the vehicle up-down direction even when used as an infant seat. Is set to the optimum angle θ1 (= approximately 35 degrees), the child can be seated on the child seat body 14 in the optimum posture in any case. Moreover, since a part of the reclining mechanism (the bulging portion 60 and the protruding portion 62) is used, it is not necessary to separately provide a component for setting the angle, and the structure can be simplified and the cost can be reduced.

[0054]

[Effect of device]
