Description

[Detailed description of the invention] Book IiI! jj is a support in a car seat, specifically a support with a so-called spring deck structure in which a T/W body is placed on the line lI.
The lines from j1111 to 8th figure show the conventional support, and the ζO support Δ is a glossy body made by alternately inserting and crossing ao*mm to t, ismu- in the horizontal direction and paper cords in the vertical direction. It is made by tensioning the shaft of 7 rod-shaped rods with # of tensile coils.

In the figure -) The tassel consisting of the material is the epidermis. The glossy body is hooked all over and placed on top of it.
Usability 1l-jX
It is known for its great qualities.

However, this support gradient is connected to a large number of O tension coils.
In order to reduce the weight of the seat O, we must use a tension coil spring (2) at t'.
However, the purpose of the present invention is to reduce the cost of the conventional support without impairing its performance. .

Vehicle seat support 01 according to the rounded Omoto q4 that achieves the above objectives! In this case, the ζro is curved in the form of an rR- plane, and is arranged at a predetermined threshold. This device is characterized in that a supporting plate consisting of a connecting member that connects with each other is stretched by connecting pieces of a frame-like frame made of KSit. That is, in the present invention, the foamed material O by conventional O hot molding is applied to the sash carbon material placed on the support.
This was done by paying attention to the fact that when a high elastic foam material such as high elastic urethane is used for the down movement, a mutual selling effect occurs.
It is possible to use a structure that eliminates the tension coil spring, thereby reducing its weight and cost.

The embodiments of the present invention will be described below as EWK%. The iris map has #Ii line-1 curved into a substantially U-shape, and two lines O#I

In addition, an increase in the amount of deflection and resistance to shoe resistance can be obtained, and the dimensional margin can be provided to the one-round net wrapper, and assembly can be facilitated by attaching the bottle to the tension rod.

A steel wire is inserted in this state to increase the amount of vertical binding of the steel shaft.

In FIGS. 11 and 12, the bent portions of the steel wire 011 are bent in a stepped manner in the same plane direction and connected to each other by a belt-shaped connecting member -1-. Tsukubagi material - 1 wheel is a lower piece made of cardboard or synthetic resin plate (4j

Figure 16 shows that the connecting member is made of a flexible material such as cloth, with exaggerated bends (44&) (44-) on both ends, and is identified to the frame to support *(&)o brittleness. It has been adjusted.

The items shown in Figures 11, 12, 14 stripes, and 16 irises are all made of steel! 101jA part is connecting member 41II
The rolling load sandwiched and reinforced by I4II4 is dispersed, improving durability, and the shape of the bottom 1irO receiver of the comb material placed on the upper surface of the material can be increased.

7 wires are strung with connecting pieces (GSA) made of elastic rings, and the SI members are... S-wires, wires, foam materials, etc. are placed inside the flexible pipe. (Fig. 20 e)), a helical spring covered (Fig. 20 ←)), an elastic member such as a rubber 8 rod, and the cross-sectional shape can be arbitrary, for example, No. tsll&), ← ), O is considered. When such a connecting member 1 is used, the steel wire can provide a tn margin in the wave II, thereby increasing the amount of *m and facilitating the assembly. When using an elastic cylinder as nine connecting pieces (2 Tatsumi),
The zero elasticity makes it easier to attach the supporting plate (&) and improves the bending performance.

Figures 21 and 22 are connecting members that are made of soft synthetic resin or rubber and are formed into a roughly ladder shape.This connecting member has a curved shape as shown by the chain line in Figure 11822. Bend it and insert the Si wire ring in a crosswise manner. (2) − is applied with tension.

Note that the support plate (&) shown in the above embodiment is formed by film-molding the support plate (&) in the cushion plate, and attaches the connecting piece (&) to the frame 04.
)- is also optional. And the steel [11$
The amount of deflection of the ring can be adjusted by changing the interval at which it is attached to the tension rod, its thickness, etc.

The present invention has the above configuration. Therefore, the support plate can obtain a predetermined amount of deflection by using a large number of curved steel wires and a connecting member that connects the substantially centers of the large number of wires to each other. Since there is no need to fix it to the frame, the tension coil dne is unnecessary!
As a result, the weight can be reduced, the weight of the seat can be significantly reduced, and the seat can be provided at a low cost. Furthermore, the support plate is deflected as a whole, and the amount of deflection can be adjusted by adjusting the intervals between the steel wires that constitute its constituent members, so there is no risk of deteriorating the performance of conventional products.

Therefore, the intended purpose can be achieved.
