Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a folding seat for an automobile, and more particularly to a seat that facilitates the folding operation.

<Prior Art> In hatchback type and van type automobiles, the seat back of the rear seat is folded onto the seat cushion in order to expand the rear cargo space. .

FIGS. 4 and 5 show a conventional example of this folding seat, in which a rotatable lock piece 2 is attached to the outer surface of the seat bag 1, and this lock piece 2 is attached to a lock pin ( (not shown), the seat bag 1 stands up against the seat cushion, and by releasing this engagement, the seat bag 1 is folded.

<Problems to be solved by the invention> However, in such a folding seat, in order to facilitate operation, it is necessary to make the lock piece 2 protrude more forward than the backrest surface of the seat back 1, which results in poor appearance and However, there is a problem in that it is difficult to perform an operation to release the lock.

<Means for Solving the Problems> Therefore, the present invention was devised to solve the above problems.One end of the strap hooks onto the lock piece and the other end of the strap, which transmits the unlocking force to the lock piece, is connected to the outer surface of the seat bag. At the same time, the middle part of the strap is folded back by the engaging member inside the seat bag to change the operating force for unlocking. The other end of the strap is led out along the main part from an opening formed at the boundary step between the upper swollen part of the seat bag and the main part. Therefore, the strap can be set in the direction that is easiest to operate with the intervention of the engaging member.

<Embodiment> FIG. 1 is a side view of an embodiment of the present invention, and FIG. 2 is a side view of its essential parts.

A lock piece 2 is rotatably attached to the outer surface of the seat back 1 and is designed to engage with a lock pin (not shown) on the vehicle body, and the engagement of the lock pin and the lock piece causes the seat back 1 to lock onto the seat. The seat bag 1 stands up against the cushion 6, and upon release, the seat bag 1 is folded onto the seat cushion 6. In this case, it is preferable that the pin 7 of the lock piece 2 is provided with biasing means (not shown) such as a torsion spring to bias the lock piece 2 in the direction of engagement with the lock pin.

One end of a strap 3 is hooked onto such a lock piece 2 so that a lock release force is transmitted. This strap 3 is in the form of a long tape, and is inserted through the seat bag 1, with the other end leading out to the front outer surface of the seat bag 1. Moreover, the middle part of this strap 3 is folded back and comes into contact with an engaging member 4 buried in the seat bag 1 above the lock piece 2, and by pulling the other end of the strap downward, the lock piece 2 The lock is released by rotating the lock upward. In this embodiment, the engaging member 4 is formed of a roller 9 rotatably attached to a horizontal shaft 8, but it may simply be a bar stretched in the lateral direction of the seat bag. The other end of the strap 3 is led out along the main part 1b from an opening 10 formed at a boundary step 1c between the upper bulge 1a of the seat bag 1 and the main part 1b. A guide piece 5 made of synthetic resin is attached to this opening to prevent the exit portion of the seat bag from deforming due to the force acting on the strap.

Figures 3A and 3B show a mode in which the other end of the strap is led out to the front outer surface of the seat bag; Figure 3A is led out to both sides of the seat bag 1, and Figure 3B is led out to the center of the seat bag. Therefore,
Figure A applies to a seat with lock pieces attached to both sides of the seat bag, and Figure B applies to a seat with lock pieces attached to one side.

With this configuration, simply by pulling the other end of the strap 3 downward, the lock piece 2 rotates in the unlocking direction and is released from engagement with the lock pin.

<Effects of the invention> According to the invention as described above, the end of the strap that is hooked to the locking piece is led out to the outer surface of the seat bag, and the strap is folded back by the engaging member, so that the lock can be released by simply pulling out the strap. It becomes possible and the operation becomes easy. In addition, the lock can be released by operating the strap, and there is no need to operate the lock piece, so there is no need for the lock piece to protrude from the seat bag.Furthermore, most of the strap and the engaging member are buried within the seat bag. In addition, since the lead-out opening at the other end of the strap is formed at the boundary step between the upper bulge and the main part of the seat bag, it is difficult to see from the outside, and the lead-out end of the strap is formed along the surface of the main part of the seat bag. This improves the appearance of the sheet.

Claims (1)

[Claims for Utility Model Registration] In a seat in which the seat bag is raised and folded by engaging and disengaging a lock pin on the vehicle side and a lock piece on the seat back side, one end of a strap that releases the lock is hooked to the lock piece. At the same time, the other end is folded back by an engaging member provided in the upper bulge in the seat bag so that it runs along the main part from the opening formed in the boundary step between the upper bulge and the main part of the seat bag. A folding sheet characterized by being guided outward.
