[Industrial applications]

 The present invention relates to a vehicle seat, and more specifically, it relates to a vehicle seat including a seat cushion and a seat back which can be tilted forward on the seat cushion, and a headrest is provided at an upper end of the seat back. .

[0002]

[Prior Art]

 2. Description of the Related Art Conventionally, in a rear seat of an automobile or the like, a configuration is widely known in which a lower end portion of a seat back is rotatably supported by a rear end portion of a seat cushion and the seat back can be tilted forward on the seat cushion. With such a configuration, the storage space in the vehicle compartment can be effectively used, and in addition to the so-called trunk through, the habitability and practicality in the vehicle compartment can be improved.

In such a seat, a headrest is detachably attached to a through hole formed at an upper end of the seatback via a headrest station, and a lock claw provided on a back side of the seatback and a vehicle body side are attached. The seat back is fixed to the vehicle body by a lock mechanism such as a striker provided in the vehicle.

[0004]

[Problems to be solved by the device]

 In the above-mentioned seat structure, when the seat cushion of the rear seat is tilted forward, the headrest at the upper end of the seat back collides with the back side of the front seat. Therefore, it is necessary to remove the headrest from the seatback before tilting the seatback forward, but the conventional configuration has a drawback that there is no place to store the removed headrest. Further, as a lock mechanism, a striker needs to be provided on the vehicle body side, and a lock claw and an operation knob have to be provided on the seat cushion side.

An object of the present invention is to fix the seat back on the vehicle body side without providing a separate lock mechanism and to store the headrest at an appropriate position when the seat back is tilted forward. It is intended to provide a vehicle seat that is highly comfortable and practical.

[0006]

[Means for Solving the Problems]

 The present invention has been made in view of the above-mentioned problems, and a seat back which can be tilted forward on a seat cushion is formed with an insertion hole for a headrest stay which penetrates from an upper end portion to a rear portion, and a lower end of the insertion hole. A locking portion is formed on the vehicle body side behind the seat back facing the seat back, and the stay penetrates through the insertion hole and is detachably locked to the locking portion.

[0007]

[Action]

 According to the present invention, the headrest stay is penetrated through the insertion hole formed in the seat back, and the head rest stay is locked by the locking portion provided on the vehicle body side behind the seat back. Can be fixed on the side. When the seat back is tilted forward, the headrest stay can be pulled out from the locking part and the insertion hole to remove the headrest.The removed headrest should be tilted again after the seatback is tilted. Can be locked to.

【Example】

 Hereinafter, a vehicle seat according to the present invention will be described in detail with reference to the drawings. 1 and 2 respectively show an outline of an embodiment of the present invention, and hereinafter, the case where the present invention is applied to a rear seat for an automobile will be described.

The seat 1 includes a seat cushion 2 attached to the vehicle body 5 side, and a seat back 3 pivotally supported on the rear end side of the seat cushion 2. The seat back 3 rotates about a pivot shaft 7 and can be tilted forward on the seat cushion 2 as shown in FIG. In FIG. 1, reference numeral 11 is a front seat, and 12 and 13 are seat cushions and seat backs.

A headrest 21 is provided at the upper end of the seat back 3, and a pair of left and right headrest stays 22 are provided below the headrest 21. The headrest 21 can adopt various conventionally known structures, and the headrest stay 22 is not limited to the left-right pair. Further, a mechanism for adjusting the vertical position of the headrest 21 and the tilting angle of the front and rear can be additionally provided.

The seat back 3 is formed with an insertion hole 24 penetrating from the upper end portion 3 a to the back surface portion 3 b, and the headrest stay 22 is inserted into the insertion hole 24. A stay holder 26 having a lock mechanism for the headrest stay 22 is attached to the upper end 24a of the insertion hole 24. Further, the lower end 24b of the insertion hole 24 is formed in an elliptical shape that is vertically long. As shown in FIG. 1, when the headrest stay 22 is inserted through the insertion hole 24, the headrest 21 tilts forward. However, a desired angle may be set by an attached mechanism for adjusting the longitudinal tilt angle. It is a thing.

A locking bracket 31 as a locking portion is fixedly provided on the vehicle body 5 side behind the seat back 3 facing the lower end 24b of the insertion hole 24. The locking bracket 31 is attached so as to be substantially aligned with the insertion hole 24 when the seat back 3 is in a seated state, and the headrest stay 22 protruding rearward of the seat back 3 from the lower end 24b of the insertion hole 24. Is inserted into the locking bracket 31 and locked. Alternatively, the insertion hole 24 may be formed to be relatively large, the headrest stay 22 may be loosely fitted, and the inclination of the seat back 3 may be changed. Further, a locking hole may be formed on the vehicle body 5 side as the locking portion.

With this configuration, the seat back 3 can be fixed only by locking the head rest stay 22 fixed by the locking mechanism on the stay holder 26 side to the locking bracket 31. When the seat back 3 is tilted forward, after removing the headrest 21, as shown in FIG. 2, if the headrest stay 22 is inserted into the locking bracket 31 and locked, a large luggage can be stored. In this case, there is no risk that the headrest 21 will move inside the vehicle or become an obstacle.

It should be noted that the present invention is not limited to the structure of the embodiment described above, and it is of course possible to appropriately change and use the shape and structure of each part, and various modifications of the headrest 21, the locking part and the like are possible. Can be adopted. For example, as shown in FIG. 3, if the present invention is applied to a trunk-through type seat 1, the practicality can be further enhanced. Further, in the above-mentioned embodiment, a description will be given of a rear seat for a four-seater vehicle. However, it can also be applied to seats of so-called midship type two-seater cars and other vehicles. Further, if a plurality of insertion holes 24 and locking brackets 31 are provided, a seat sliding mechanism and a reclining mechanism can be additionally provided. By appropriately changing the insertion holes 24 and the like through which the headrest stay 22 is inserted, It is possible to change the front-back position of 1 and the inclination angle of the seat back 3.

[0015]

[Effect of the device]

 The above is the configuration of one embodiment of the vehicle seat according to the present invention. According to this configuration, the headrest stay is penetrated through the insertion hole formed in the seat back and is provided on the vehicle body side behind the seat back. By locking the seat back, the seat back can be fixed to the vehicle body without separately providing a lock mechanism, which can significantly improve the economical efficiency. When the seat back is tilted forward, the headrest stay can be pulled out from the locking part and the insertion hole to remove the headrest.The removed headrest should be tilted again after the seatback is tilted. It is possible to obtain a vehicle seat that can be locked to the vehicle seat and has excellent operability and improved practicality.
