4 and protrudes toward the vehicle cabin by a predetermined distance.

On the other hand, the passenger side instrument panel 2
Child seat 1 with room without interference with 2
In order to perform the mounting operation of the front seat 0, the front passenger seat 12 is moved rearward of the vehicle body (FIG.
In (b), the slide is moved backward as far as possible toward the right side (that is, the rear seat side) to secure a certain working space in the vehicle interior. Then, the child seat 10 facing backward with respect to the front direction of the vehicle is placed on the seat seat surface 15 of the passenger seat 12 which is away from the instrument panel 22 on the passenger seat side,
The rear side of the vehicle body of the child seat 10, that is, the passenger seat 12
The two connectors 17 on the left and right sides which are close to the backrest 20 are respectively inserted into the anchors 21 on both sides of the passenger seat 12 and fastened and fixed. As a result, the seat cushion 16 of the child seat 10 is firmly fixed on the seat surface 15 by the anchor 21 of the passenger seat 12.

Next, the front passenger seat 12 with the child seat 10 mounted thereon is slid forward by the front-rear adjustment mechanism toward the front of the vehicle (the left side in FIG. 3B, ie, the front passenger seat side instrument panel 22 side). The child seat 1 is moved and adjusted while gradually reducing the distance between the seat back 18 of the child seat 10 and the passenger side instrument panel 22.
The striker 19 of the rear anchor 11 is inserted into the inside of the housing from the insertion opening 23 of the attachment 13 which is fixedly fastened to the storage portion 24 of the instrument panel 22 on the passenger seat side, and is fixed and fixed. 13 (see FIG. 1). As a result, the seat back 18 of the child seat 10 is firmly fixed to the passenger side instrument panel 22 via the attachment 13 so that the child seat 10 takes an appropriate posture on the seat seating surface 15 of the passenger seat 12. become.

As described above, according to the child seat 10 of the present invention, the connector 17 corresponding to ISO-FIX is provided at each of the four left and right corners of the outer bottom of the seat cushion 16 supporting the child's buttocks of the child seat 10. It is mounted so as to be mounted on the seat seating surface 15 such as the passenger seat 12 or the rear seat provided with the anchor 21 corresponding to ISO-FIX in a front-facing or rear-facing state. Therefore, the seat cushion 16 of the child seat 10 can be easily fixed firmly on the seat seating surface 15 by the anchor 21 of the passenger seat 12, and the child seat 10 in the rearward-facing posture can be easily moved even if the child is older. 12 or the user's need to sit on the rear seat.

Further, a back anchor 11 is integrally fixed to the back side of the seat back 18 supporting the back of the child, and a striker 19 provided on the back anchor 11 is attached to the passenger side instrument. Attachment 13 fastened and fixed to storage section 24 of panel 22
The seat back 18 of the child seat 10 is attached to the attachment 1 by adjusting the front passenger seat 12 back and forth so as to be inserted into the attachment 13 from the insertion opening 23 of the attachment 1.
3 is firmly fixed to the passenger side instrument panel 22. Accordingly, it is possible for even a female user to easily and surely prevent the swing of the seat back 18, and to stably maintain an appropriate posture of the child seat 10 on the seat surface 15 of the passenger seat 12. As a result, the convenience and workability of the user are improved, and the child seat 10 is prevented from being erroneously attached. Further, since the child seat 10 is not directly fixed to the passenger side instrument panel 22, the projecting distance of the rear anchor 11 can be minimized, and the handling performance of the child seat 10 in the passenger compartment is not impaired.
In addition, the shape of the attachment 13 is formed into, for example, an L shape in a side view so as to correspond to each vehicle type, so that the child seat 10 can be adapted to any vehicle in which the storage portion 24 is formed. Become.

Further, when the seat back 18 of the child seat 10 is fastened and fixed to the passenger side instrument panel 22 via the attachment 13, a fastening signal is output from the latch fastening sensor 26 to the airbag control unit 25. , The passenger-side airbag 28 is always deactivated. Thus, even when the ignition determination based on the detection value from the G sensor 27 is ON, the passenger airbag 28 does not rapidly inflate, and the child seat 1
In addition to avoiding interference with zero, the passenger seat 12 does not need to be retracted except during the operation of attaching the child seat 10, so that the living space of the rear seat is prevented from being narrowed.

Furthermore, the user can confirm that the passenger-seat-side airbag 28 is not operated by turning on the warning lamp 32. Therefore, the user may feel uneasy about whether or not the child seat 10 is properly worn. It is possible to solve the problem and increase the sense of security, thereby improving user convenience.

When it is desired to attach such a child seat 10 to the passenger seat 12 in a forward direction, as shown in FIG. 4, the seat back is fixed at a predetermined position on the front side of the vehicle body in the backrest 20 of the passenger seat 12. A latch 33 is attached, and the seat back fixing latch 33 and the rear anchor 11 of the child seat 10 facing forward are fastened and fixed, and the connector 17 on the rear side of the vehicle body of the child seat 10 and the striker 21 of the passenger seat 12 are fastened. Fix it. Similarly, when it is desired to attach the child seat 10 to the rear seat (not shown) in a forward direction, the seat back fixing latch 33 is attached to a predetermined position of the backrest of the rear seat. By those things,
The front-facing child seat 10 can be stably and easily attached to the passenger seat 12 or the rear seat, and the child seat 10 is firmly fixed to the passenger seat 12 or the rear seat by three-point connection. It is not necessary to attach a tether strap, so that the cost of parts can be reduced, and at the same time, the posture and the head of the child at the time of sudden braking or a forward collision can be reduced.

As a result, it is possible to improve safety, wearability and workability when attaching the frontward or rearward facing child seat 10 to the passenger seat 12 and to increase the stability of the child seat 10 when the seat is mounted. Accordingly, it is possible to realize the child seat 10 in which the protection of the user is enhanced.

[0032]

As described above, according to the child seat of the present invention, it is possible to improve workability when the child seat is mounted rearward on the passenger seat side of the passenger seat provided with the airbag system. A child seat can be provided that stably and reliably fixes the child seat to the seat seat surface, prevents wobbling of the seat back, and avoids interference with the airbag and does not narrow the living space of the rear seat. .
