Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement in the skin suspension structure of an automobile seat.

(Prior Art) Conventionally, as shown in FIG. 6, in an automobile 1 such as a truck, a foldable rear seat 3 is provided behind a front seat 2.

The rear seat 3 has a seat back 5 fixed to a back panel 4 in the vehicle interior, and a lower surface fixed to a hinge member 7 pivoted to a floor panel 6.
It is comprised of a seat cushion 8 that can freely swing between a retracted position (the solid line state in the figure) facing the seat cushion.

By the way, as shown in FIGS. 7 to 9, the seat cushion 8 has a seat pad 11 supported by a seat frame 10 whose outer surface is covered with a skin (seat trim) 12.
A recess 11a into which the hinge member 7 fits is formed on the lower surface of the hinge member 1, and a hinge member mounting bracket 1 fixed to the seat frame 10 is formed at the bottom of the recess 11a.
3 is facing, a square hole 12a is made in the skin 12 corresponding to the recess 11a, and the square hole 12a is opened.
Slits are formed at the four corners of the hinge member 7 to prevent wrinkles when the hinge member 7 is fitted.

To assemble the seat cushion 8 to the vehicle body, the seat back 5 is fixed to the back panel 4, the hinge member 7 is fixed to the floor panel 6, and the hinge member 7 is swung to the storage position. 6, insert the seat cushion 8 from above between the back panel 4 and the hinge member 7, insert a bolt (not shown) from the hinge member 7 side, and attach the hinge member. Metal fittings 13
It is designed to be fastened to the nut portion 13a of the.

However, since the outer skin 12 corresponding to the recess 11a of the seat pad 11 is in a raised state with respect to the recess 11a, the seat cushion 8
When inserting between the seat bag 5 and the hinge member 7, the hinge member 7 causes the skin 12 to be inserted into the recess 11a.
There was a problem that the skin 12 could not be pressed in properly and the skin 12 would protrude from the hinge member 7, or the tip of the hinge member 12 could get caught in the square hole 12a and the skin 12 could be torn.

(Purpose of the invention) The present invention was made in order to solve the above-mentioned conventional problems, and the seat cushion can be assembled smoothly without protrusion or tearing of the skin when assembling the seat cushion. The purpose of the present invention is to provide a skin suspension structure that enables the following.

(Structure of the invention) Therefore, in the present invention, a flexible protector is sewn along the peripheral edge of a square hole made in the skin corresponding to the recess of the seat pad, and the protector is secured to the hinge member mounting bracket. A hook part is provided along the circumferential wall of the recess to suspend the outer skin together with the protector.

(Effects of the invention) According to the invention, when the hook part of the protector sewn to the peripheral edge of the square hole in the skin is locked to the hinge member mounting bracket fixed to the seat frame, the skin is moved together with the protector into the recess. Since the skin is suspended along the peripheral wall, the skin will not protrude when pressed by the hinge member or be torn by the hinge member, and the appearance will also be improved.

Furthermore, since the protector plays the role of a guide rail when inserting the hinge member, assembly can be performed smoothly and work efficiency can be improved.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 3, the seat cushion 16 of the rear seat has a thick seat pad 18 supported by a rectangular frame-shaped seat frame 17, and the outer surface of the seat pad 18 can be opened and closed with a fastener 19. It is covered with a bag-shaped skin 20.

A recess 18a into which the hinge member (see FIG. 6) fits is formed on the lower surface of the seat pad 18, and a seat frame 17 is formed at the bottom of the recess 18a.
A hinge member mounting bracket 22 fixed to is exposed. The hinge member attachment fitting 22 is provided with a nut portion 22a for fastening a bolt inserted from the hinge member 7 side.

On the other hand, a square hole 20a is bored in the skin 20 corresponding to the recess 18a. As shown in FIGS. 4 and 5, a flexible synthetic resin protector 21 formed in an inverted U-shape is provided slightly outwardly, and both side portions 2 of the protector 21 are provided.
1a, 21a inwardly along the peripheral edge 20b of the square hole 20a, and thread 23 to tighten the epidermis 2.
Sew on 0.

A hook portion 21c that can be engaged with the elongated hole 22a of the hinge member attachment fitting 22 is integrally formed in the center portion 21b of the protector 21.

The hook portion 21c is connected to the hinge member mounting bracket 22.
When locked in the elongated hole 22a, both sides 21a,
The length is set such that the skin 20 is hung along the peripheral wall of the recess along with the skin 21a.

If the configuration is as above, the protector 21
After covering the seat pad 18 with the skin 20 sewn in advance along the peripheral edge 20b of the square hole 20a and closing it with the fastener 19, the hook portion 21c of the protector 21 is attached to the hinge member mounting bracket 22. When the protector 21 is locked in the elongated hole 22a, the center portion 21b and both side portions 21a, 21a of the protector 21 are drawn into the recess 18a.
The skin 20 becomes suspended along the peripheral wall.

With this protector 21, the seat pad 1
A container-shaped recess is formed in the epidermis 20 along the recess 18a of No.8.

Therefore, when inserting the seat cushion 16 between the seat bag 5 and the hinge member 7 shown in FIG.
Since it is pressed into the recess 18a by the hinge member 7, there is no fear that it will protrude when pressed by the hinge member 7 or that the tip of the hinge member 7 will get caught in the square hole 20a and the skin 20 will be torn. .

Further, both sides 21a, 21 of the protector 21
Since a serves as a guide rail when inserting the hinge member 7, assembly can be carried out smoothly.
