Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile seat, and more particularly to a skin suspension structure for an automobile seat having a spring therein.

The design of automobile seats is important, and the surface of the seat has a hanging shape, as shown in section A in Figure 1.

FIG. 8, which shows a known structure, is a vertical sectional view taken along the line X-X of the seat shown in FIG. A bag-shaped portion 27 is formed at the lower portion, and a wire 33 serving as a locking member is inserted therethrough.

Further, the first cushion material 24 is provided with a horizontal groove 25, into which a hanging member 26 is inserted, and the wire 33 is inserted into the frame 21, which is the main strength of the seat.
As shown in the figure, the hanging member 26 is clipped to a tensioned spring 22, and in this state, the hanging member 26 is tensioned.

Therefore, the cushion material 24 is the skin 2 that continues to the hanging member 26.
3, the skin 23 sinks down to form a hanging shape.

By the way, some automobiles, especially passenger cars, are designed to improve seating performance, raise the eye point, or have an engine service hole cover at the bottom, such as the seat of a cab-over type automobile, to prevent collisions with the cover. The spring may protrude upward.

In the conventional suspension structure of a seat having this type of spring, the lower end of the bag-shaped part 21 of the suspension member 26 is linear as shown in FIG. In FIG. 9, the length from the skin 23 to the lower end of the hanging member 26 is set based on both ends 29 and 29 of the hanging member 26 that are farthest from the spring 22. Although the portions 29 and 29 are stretched, the center portion 28 is relaxed, so that the center portion of the skin 23 is lifted up compared to both ends as shown by the two-dot chain line, resulting in an unsightly appearance.

Therefore, the present invention aims to eliminate the drawbacks of this conventional structure and provide a seat with an excellent appearance.

Hereinafter, the present invention will be explained in detail based on FIGS. 2 to 4.

FIG. 2 is an enlarged vertical cross-sectional view of the main part of a seat having a hanging structure according to the present invention, FIG. 3 is a hanging member, and FIG. 4 is a cross-sectional view of the main part. An engaging part 9 is formed in the center above the shaped part 8.

This shaped portion 9 is formed by sewing when the hanging member 9 is made of cloth, or by welding or sewing when using a resin such as vinyl chloride, and can take various forms depending on the material.

Further, a wire 10 serving as a locking member is inserted through the upper portion of the locking portion 9, and the frame 1 of the wire 10 is inserted as shown in FIG.
When clipping the spring 2 tensioned to the spring 2, both sides 12, 12 of the wire 8 located on the outside of the engaging portion 90 are attached.
is pulled down inside the bag-like part 8, and is clipped to the lower end of the bag-like part 8, with both ends of the hanging member 50 being pulled, and the center part 34 of the wire 10 located at the upper part of the engaging part 9 , is prevented from being pulled downward by the engaging portion 9,
The hanging member 5 is clipped in a state where it is in contact with the engaging portion 9 and the center of the hanging member 5 is pulled.

The height of the engaging portion 9 from the lower end of the hanging member 5 is determined by the shape of the spring 2.

That is, since this height is equal to the height from the position where both ends 12.12 of the wire 10 are clipped to the spring 2 to the top of the spring 20, the hanging member 5 is
The outer skin 3 following the hanging member 5 forms a suspended shape without lifting at each position, as the both sides 7, 7 are subjected to a substantially uniform tensile force.

Next, another embodiment of the present invention will be described. In FIG. 5, the lower end of the hanging member 5 is sewn along the spring shape. According to this, the wire 10 comes into contact with the hanging member 5 along its entire length. , the tensile force becomes more uniform at each position of the hanging member 10 than in the above embodiment, and the hanging shape of the skin becomes better.

In FIG. 6, the wire 10 is fastened from both ends of the hooking part 9 to the lower end of the hanging member, making it easy to insert the wire 10 into the bag-shaped part.

Furthermore, it goes without saying that the present invention can be applied to springs in which the spring shape is not limited to those that protrude upward, but are recessed downward, or have irregular shapes.

In the above embodiment, a wire was used as a locking member to clip the spring, but as shown in FIG. The same effect can be obtained by sewing the locking member 15 to the hanging member and clipping the locking member 15 to the spring.

As described above, the present invention solves the conventional drawback of making it difficult to maintain a suspension shape for the skin when the spring is curved upward, and provides a seat with an excellent appearance. This is of great practical benefit, as it can be used in mass-produced seats.
