DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat and, more particularly, to an automobile seat having an improved structure for fixing an end of a skin trim.

[0002]

2. Description of the Related Art The structure of a seat is disclosed in Japanese Utility Model Laid-Open No. 3-125.
No. 499, the lower surface of the seat cushion and the rear surface of the seat back are formed of a synthetic resin panel.
There is a synthetic resin panel in which an edge portion of a skin trim covering a seat cushion or a seat back is fixed to a peripheral portion of the synthetic resin panel.

[0003] As a fixing structure of the end portion of the skin trim of this type, first, a groove portion opening downward is formed along the peripheral edge portion of the synthetic resin panel, and the groove portion is mounted in advance in the groove portion at the end portion of the skin trim. By engaging the resin hook,
The end of the skin trim is attached to the periphery of the synthetic resin panel.

[0004] The end of the skin trim has an inner surface ("inside" means a seat cushion (or a seat back)).
(The outer side means the opposite side). The synthetic resin hook is attached by sewing.

[0005]

However, in such a conventional technique, the end of the skin trim is formed so as to be sharply bent at the opening end of the groove so as to enter the groove. Therefore, there is a possibility that the skin trim may be torn due to the repeated load being applied to the sharply bent portion due to the tension applied to the skin trim when the occupant is seated.

Conventionally, as a countermeasure, the skin trim is made thick to withstand the repeated load at the sharply bent portion, or a patch is applied to the back surface of the corresponding portion of the skin trim to repeatedly load the repeated portion at the sharply bent portion. To be able to withstand.

[0007] For this reason, increasing the thickness of the entire skin trim by only requiring the end of the skin trim causes a rise in cost, and cannot meet the demand for cost reduction.

Further, applying a patch to a part of the back surface of the skin does not increase the cost as compared with the case where the entire skin trim is made thicker as described above, but it is difficult to align the patch. The cause of the rising costs will remain the same.

The present invention has been made by paying attention to such a conventional technique, and does not cause breakage from the mounting portion of the skin trim, and can reduce the cost and achieve a good-looking mounting. The purpose of the present invention is to provide a sheet that can be used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to FIGS. In the following description,
“Inside” means the center side of a seat cushion (or seat back) described later (A direction in FIG. 2), and “outside” means the opposite side (B direction in FIG. 2). .

Reference numeral 1 denotes an automobile seat, which comprises a seat cushion 2 and a seat back 3.

In this embodiment, the seat cushion 2
Also, the seat back 3 is substantially similar in construction, and therefore, the seat cushion 2 will be described below as a representative.

The seat cushion 2 has a pad, a spring, and the like attached to a seat cushion frame (not shown), and the surface other than the lower surface is covered with a skin trim 4. The lower surface is formed of a synthetic resin panel 5, and an end 6 of the skin trim 4 is attached to a peripheral edge of the synthetic resin panel 5.

More specifically, the peripheral portion of the synthetic resin panel 5 is composed of a straight line portion 5a and a corner portion 5b, and a groove portion 7 that opens downward is formed in the peripheral portion.

The groove 7 has a shape in which the peripheral edge of the synthetic resin panel 5 is formed in a downward U-shape, and the inner surface of the inside (that is, the direction A) has a partially cut and raised inner surface. One claw 8 is appropriately protruded into the groove 7.

On the other hand, reference numeral 9 denotes a synthetic resin hook, as shown in FIG.
As shown in the figure, the synthetic resin panel 5 is formed in a linear shape to be inserted into the groove 7 of at least the linear portion 5a along the peripheral portion.

The cross-sectional shape of the synthetic resin hook 9 is a plate shape having a predetermined thickness, and the tip thereof has an inward second claw 11.
