Description

[Detailed Description of the Invention] This invention relates to a seat device for an automobile.

Generally, the seat cushion of an automobile seat has a fourth
As shown in FIG.
0 and 20 bulge upward, and the central portion 21 is formed in a horizontal shape somewhat lower than the both side portions 20 and 20.

In this way, both side parts 20, 20 and the central part 21
When the seat cover 23 is attached to the seat cushion 22 having different heights, the seat cover 23 becomes like a bridge between the bulging side portions 20, 20, and the seat cover 23 and the seat cushion 22
This results in the inconvenience that a gap 24 is formed between the central portion 21 of the

Therefore, in order to eliminate the above-mentioned inconvenience and attach the seat cover 23 properly along the upper surface of the seat cushion 22 in pairs, a method is proposed as shown in FIG. 6 and disclosed in Japanese Patent Publication No. 52-27589. An upper wire 25 and a lower wire 26 are buried inside the seat cushion 22 vertically and approximately parallel to each other, as shown in FIG.
The upper wire 25 is supported by the seat cover 23 via the sleeve 27, and both the upper and lower wires 25,
A vehicle seat in which 26 is fixed with a claw ring 28 has been proposed. This structure has seat cushion 2.
Since the lower wire 26 buried in the lower part 2 is difficult to bend, when the occupant is seated, the hardness of the wires 25 and 26 is felt in the lower part 28 of the human body, which gives a sense of discomfort and is uncomfortable to sit on.

This idea was created in view of the above-mentioned drawbacks of the conventional technology.It not only allows the seat cover to be attached uniformly and properly against the surface of the seat cushion, but also improves the comfort of the seat by eliminating the discomfort felt when sitting. The purpose is to provide an improved automobile seat device.

Embodiments of this invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a seat cushion made of an elastic material such as polyurethane foam, with side portions 2, 2 bulging upward, and a central portion 3 that is slightly larger than both side portions 2, 2. lower,
It is formed horizontally, and the lower wire 4 is buried therein.

The lower wire 4 is, for example, a steel wire, and has a crank shape in which an outer portion 4a and an inner fixed portion 4b are continuous.
The grooves 5 are formed along the boundaries between the side portions 2, 2 and the center portion 3 of the seat cushion 1, and extend into a recess 6 formed downwardly.

In Figure 3, 7 is a seat cover made of natural fibers.
It is made of synthetic fibers, synthetic resin sheets, etc. The upper wire 9 is formed of a steel wire or a rod-shaped plastic material, and is supported by the seat cover 7 through or inserted into the sleeve 8, or the upper wire 9 is formed by integrally forming a rod-shaped part and a flat plate part with a plastic material. The seat cover 7 is supported by the seat cover 7 by sewing the flat plate portion. The upper wire 9 is fitted into the groove 5 of the upper seat cushion 1. Therefore,
The fixed portion 4 of the lower wire 4 is located below the upper wire 9.
b is located, and the upper wire 9 is fixed by the fixing member 10.
and the fixed part 4b of the lower wire 4 are bound together.

The edge portion 7a of the seat cover 7 is connected to the seat frame 11.
It is bound by a fixing member 12.

In the above configuration, the lower wire 4 is formed into a crank shape in which the outer portion 4a and the inner fixed portion 4b are continuous, and the lower wire 4
Since the fixed part 4b located on the inside of the lower wire 4 and the upper wire 9 are connected by the fixed member 10, when the occupant is seated, the fixed part 4b of the lower wire 4 is connected to the outer part as shown by the imaginary line X in FIG. 4a, the upper wire 9 can be easily bent more than the outer part 4a, and the upper wire 9 can also be pulled down with the fixed part 4b of the lower wire 4, so that the stiffness of the wires 4 and 9 can be adjusted to the lower part of the human body. It's comfortable to sit on without making me feel like I'm 13.

In the above embodiment, the lower wire 4 has a crank shape, but the lower wire 4 can also have a wave shape.

As explained above, according to this invention, the lower wire has a continuous portion that is located outside the upper wire and a fixed portion that is located below the upper wire and is tied together with the upper wire. Since the fixed part of the lower wire and the upper wire are connected by a fixed member, when the occupant is seated, the lower wire bends and pulls down the upper wire, eliminating discomfort when seated and improving seating comfort. It has the advantage of being able to improve
