Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a treatment structure for the end portion of a covering material of a seat cushion in a vehicle seat.

(Prior Art) In a vehicle seat, the upholstery 2 of the seat cushion 1 is clipped to the cushion frame 5 at both end portions 3 and 4 at both ends thereof, as shown in FIGS. 5 and 6. Furthermore, a cushion finisher 6 that covers the slide rail, devices, etc. is attached to the side surface thereof.

Therefore, in the above-mentioned conventional example, when attaching the facing material end portions 3 and 4 of the seat cushion 1, one end 3 is first treated, and then the other end 4 is strongly pulled and the cushion frame 5 is attached. Since it is necessary to clip the product, the tension force may cause wrinkles and other variations in the product, and the shape of the cushion is complex, making it difficult to use the cushion finisher 6. Since it is difficult to attach it tightly to the side surface of the facing material 2, a gap 7 is created between the two members 2 and 6, and this gap 7
This results in dust, dirt, etc. entering the seat and causing problems in the sliding operation of the seat. Furthermore, the covering material 2 in the area where the cushion finisher 6 comes into contact may be rubbed, resulting in skin breakage or the like.

(Purpose) In view of these points, the present invention allows the facing material to be installed neatly and uniformly without creating a gap between the cushion finisher and the cushion finisher, and also prevents inconveniences such as breakage of the skin due to the above-mentioned finisher. The purpose of this technology is to provide a treatment structure for the end portion of the upholstery of a seat cushion that does not cause The end portion is fixed to the inner surface of the cushion finisher.

(Example) The present invention will be described in detail below based on the illustrated example.

1 to 3 show a seat cushion 10 to which an end treatment structure according to an embodiment of the present invention is applied, and reference numeral 11 in the figures is a cushion pad whose outer surface is made of a suitable material such as leather. It is covered with a covering material 12 consisting of. This facing material 12
The terminal portion 13 on one side (left side in the figure) is fixed by clipping to the cushion frame 15 in the same way as in the conventional case, and the terminal portion 14 on the other side is
It is formed shorter than the one side, and has a length that reaches halfway on the side of the cushion pad 11. A belt-shaped reinforcing member 17 made of a resin material or the like is attached along the end portion of the terminal portion 14, and this reinforcing member has mounting holes 17 in the longitudinal direction.
A plurality of a are formed.

Reference numeral 16 denotes a cushion finisher made of a resin material or the like, and a plurality of protrusions 16a are integrally formed in the longitudinal direction on the lower surface of the upper part of the cushion finisher.
a are inserted into the mounting holes 17a of the reinforcing member 17, and then the lower end portions are heat caulked to fix the other end portion 14 of the facing material 12. It is fixed to the slide rail main body, which will be described later, via the slide rail body. The protrusion 16a may be formed integrally, or may be formed separately, such as a mounting bracket.

Note that reference numeral 19 in the figure is a slide rail that slides on a slide frame (not shown), and its rear end is fixed to the lower end of the device 20.

Therefore, the facing material 12 is configured such that after the terminal portion 13 on one side is fixed to the cushion frame 15, the terminal portion 14 on the other side is fixed to the inner surface of the finisher 16. Moreover, the terminal portion 14 on the other side is fixed by inserting the protrusion 16a on the inner surface of the finisher into the attachment hole 17a of the reinforcing member 17 attached thereto and heat caulking, and the finisher 16 itself is finally tightened with the bolt 18. There is no variation in the tensile force, and the covering material 12 can be attached uniformly. Also, since the end portion 14 on the other side is inserted into the inner surface of the finisher 16, there is no gap between the end portion 14 and the finisher 16. This not only completely prevents the intrusion of dust and the like, but also improves the appearance.

The embodiment shown in FIG. 4 shows another means for fixing the end portion on the other side, and in this embodiment, instead of heat caulking the protrusion 26a on the inner surface of the finisher 26, it is attached to a reinforcing member. 27, and then bent and fixed.

According to this embodiment, processing work on the terminal section can be performed more quickly than in the above embodiments.

The means for fixing the other end of the covering material can be selected as appropriate depending on the material, shape, etc. of the finisher.

(Effects) As described above, according to the present invention, one end of the covering material of a vehicle seat cushion is fixed to the cushion frame, while the other end is fixed to the inner surface of the cushion finisher. As a result, when the cushion finisher is attached to the slide rail body, etc., the above-mentioned end portion is naturally pulled downward, applying a uniform tensile force to the covering material, and it is possible to provide a seat cushion with no product variation. It is something. In addition, as the end of the other side enters the inner surface of the cushion finisher, there is no gap between the end of the covering material and the cushion finisher, and dirt, etc. can enter the finisher. In addition to being able to prevent
Its appearance also improves its appearance.

Furthermore, according to the present invention, if the inner end of the cushion finisher partially comes into contact with the edge of the covering material, there will be no scratches, and this will prevent the end of the covering material from rubbing and causing skin breakage, etc. There will be no more worries.

In the above embodiment, the case where the cushion finisher was provided on one side was explained.
It may be provided on both sides.
