Description

[Detailed description of the invention]

[0001]

[Industrial application field] The present invention relates to an automobile seat (seat).
Mounting structure of shock-absorbing shock rubber provided on vehicle seats, etc. Specifically, when the seat back (backrest) that has been tilted forward is returned to its original upright state, the impact of the seatback on the seat cushion (seat) is absorbed. It relates to a shock rubber to perform.

[0002]

2. Description of the Related Art As shown in FIG. 8, in a conventional seat cushion (SC) of a bench-type rear seat, a shock rubber (1) is provided upward on a pipe frame (3) disposed at a rear end side thereof. . Therefore, when the seat back (SB) in the forward tilted state shown by the solid line is returned to the upright state shown by the chain line, the lower end of the seat back (SB) hits the rear end of the seat cushion (SC).
The impact due to B) is absorbed by the shock rubber (1) provided on the seat cushion (SC) side. In the figure, (4) is a sheet metal frame welded to the frame (3), (5) is a stopper provided at a lower end position of the seat back (SB) corresponding to the shock rubber (1), and (6) is a seat back (S).
Hind arms for connecting B) to the seat cushion (SC) so as to be able to lean forward, and (61) indicate hinge pins.

The above shock rubber (1) is mounted on a frame (3) as shown in FIG. That is, the frame (3) is in a state of a pipe material that is open at the end (30) without crushing the end (30) so as to be easily welded to the sheet metal frame (4). A cap (2) made of a flexible material (rubber or synthetic resin) is fitted into the opening of the end (30) of the frame (3) to close the opening end (30). The shock rubber (1) is attached by fastening the rubber (1) to the frame (3) with the screw (7). In FIG. 9, (31) in the figure indicates a through hole for fastening the screw (7).

[0004]

The shock rubber (1) needs to be mounted on the end (3) of the frame (3) near the hinge arm (6) of the seat back (SB). Therefore, this mounting position is the cap (2)
, The mounting space is limited by the cap (2), and there is a problem that the mounting property is extremely poor. Therefore, an object of the present invention is to improve the mounting properties of a shock rubber, which is a problem of such a conventional product.

[0005]

According to the present invention, there is provided a shock rubber mounting structure for a vehicle seat according to the present invention, in which a shock rubber and a cap are integrally connected, and the shock rubber is fixed to a frame. It is characterized by the following. The number of parts can be reduced by integrally molding the above-described shock rubber and cap with a mold.

[0006]

Since the shock rubber and the cap are integrally connected, the shock rubber and the cap can be fixed to the frame at the same time. By fixing the shock rubber, the cap can be prevented from coming out of the frame.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 to 3 show a first embodiment of the present invention, in which a frame (3) is welded at its end to a sheet metal frame (4) and a screw (7) is fastened to its upper surface side in the same manner as in the prior art. Holes are opened. An insertion hole (41) for inserting a hinge pin for rotatably connecting a hinge arm of a seat back is formed in the sheet metal frame (4).

A cap (2A) is formed integrally with a shock rubber (1A) made of a flexible elastic material such as rubber or synthetic resin via a connecting portion (6). Molded in the same form,
It is fixed by inserting the screw (7) into the vertical hole (11) and fastening it to the frame (3). The cap (2A) has a fitting portion (20) fitted in the end portion (30) of the frame (3), and a lateral hole (21) is formed in the fitting portion (20). I have.

The method of attaching the shock rubber (1A) to the frame (3) will be described first.
The fitting part (20) of A) is connected to the end part (30) of the frame (3).
And the cap (2A) is fixed to the frame (3), and the shock rubber (1A) is applied to the upper surface of the end (30). The screw (7) is passed through the vertical hole (11) of the rubber (1A), and fastened to the nut (71).
A) fixing the screw (7) with the end of the screw (7) in the fitting portion (20) of the cap (2A).
Insert the cap (2A) into the screw (7)
(Fig. 3).

FIGS. 4 to 7 show a second embodiment of the present invention. In this embodiment, an insertion slit (32) and this slit (32) are provided on the upper surface of the end (30) of the frame (3). Is provided with an enlarged locking hole (33) in a part thereof, and the shock rubber (1B) is inserted into the slit (32), and the locking hole (3) is inserted.
By fixing to (3), the shock rubber (1B) is attached to the end (30) of the frame (3).

The slit (32) is formed inward from the opening edge of the end (30). A locking projection (12) fitted into the locking hole (33) and an end (30) of the frame (3) are provided on the bottom of the shock rubber (1B).
A locking flange (14) housed in the inside is provided, and a slide groove (13) inserted through the slit (32) is provided between the locking flange (14) and the locking projection (12). ) Are formed toward the connecting portion (6). The cap (2B) connected by the connecting portion (6) is formed so that a part thereof is fitted and fixed in the end portion (30) of the frame (3).

Next, a method of attaching the shock rubber (1B) integrated with the cap (2B) will be described. First, the shock rubber (1B) is inserted into the slit (32) of the frame (3) along the slide groove (13). ), And then press the shock rubber (1B) in the direction of the frame (3) to fit the locking projection (12) into the locking hole (33). Thereby, the shock rubber (1B) is fixed to the frame (3). Thereafter, the cap (2B) is fitted into the end (30) of the frame (3) to close the open end (30).

[0013]

According to the present invention, since the cap is integrally connected to the shock rubber, when the shock rubber is attached to the narrow end of the frame, the cap can be easily attached without obstructing the cap. Can be. In addition, the mounting of the shock rubber improves the fixability of the cap and prevents the cap from falling off.
