Description

[Detailed description of the invention] The present invention is a seat K1m1 used for automobile seats etc.
do.

Automobile seats generally have a spring structure attached to the frame.
The material is made of round material, and the seat surface is suitable for obtaining a comfortable sitting comfort. This is necessary. Conventionally, the thickness and shape of the Δrad material and the structure of the spring structure have been devised to improve seating comfort.

However, if a complex structure is used, such as a combination of steel wire in the spring, it will be expensive, and
P material is also expensive, so if the thickness of P material is large, it will increase the cost. Therefore, the purpose of the present invention is to provide a seat that provides good seating comfort, has a simple gate structure, and can be manufactured at low cost.

That is, the present invention includes a frame, a plurality of spring locking parts formed along a frame so as to be movable at least in the vertical direction with respect to the frame, one end of which is locked to the spring locking part, and the other end of which is locked to the spring locking part. This seat is equipped with a tension spring that is engaged with a frame and elastically supports the flannel, and a stretch of vP material provided on the upper surface of the flannel.

Therefore, in addition to the elastic force of the base material and the do material, the elastic force of the tension p spring can be exerted, and the combination of these makes it possible to maintain an appropriate body pressure distribution. Moreover, the structure of /# flannel is extremely simple, and it can be easily manufactured by pressing, etc., and the structure of this flannel can be used. / The amount of wood used can be reduced, etc. It is possible to provide a comfortable seat at a low cost.

An embodiment of the present invention will be described below with reference to FIGS. 1-3. In FIG. 1, reference numeral 1 indicates a frame, and this frame 1 is formed into a substantially rectangular frame shape.

In addition, a support opening 1 and 2 are provided upright on one of the frames 1, that is, on the front side of the seat, and the front ends of the respective flannel 1 are pivotally supported by this support opening V and IK.

The above-mentioned parallel plate 3 is made of press-formed material, such as a steel plate, which can be provided to some extent.
・It has both ends x a * a a (
(only one of which is shown) is bent upward.

At the rear end of the mother tongue 3, a plurality of spring locking portions 5 are formed along the edge of the mother tongue. As an example, it is possible to adopt a hole which has been rounded as shown in FIG. 3, for example.

These spring locking parts 5...K, tension springs 6...
...is locked at one end. Each tension spring 6...
The other ends are each formed with a frame IK and have nine locking holes 1 and 1.
...K is locked. Therefore, the rear end of the middle flannel S is elastically supported by the tension springs 6, and the front end of the middle flannel S is supported by the support rod 2.

The /monnel 3 is supported diagonally downward so that the rear end 3b@ is lowered.Furthermore, a dowel member 8 is provided on the upper surface of the /mother flannel SO. This material a is made of foamed synthetic resin or the like having appropriate elasticity, and covers the entire upper surface of the Δ flannel S and the frame 1. The surface of the rattan material 8 is shaped so that it can be covered with an outer fabric (not shown). 9 is a round fastener insertion groove for fastening the inner outer fabric.

In addition, the thickness of the above I'spk'#a is such that the thickness is the maximum at the central part, the mid-to-back part, and the part that supports the buttocks of the person sitting on the toes. Since the structure is as follows, the body pressure of the seated person is Δ, and /9 through the material 1
The pressure is transmitted to the flannel 1, and as the flannel 1 bends according to the body pressure distribution, the middle rad material 1 also becomes elastic and the body pressure is dispersed.

★Tension spring C based on the amount of deflection of tunnel 1...
・Each expands and elastically supports the load.

Therefore, since the body pressure distribution is appropriate and vibrations from the vehicle body can be absorbed, it is easier to obtain a comfortable seat.

Moreover, according to the above embodiment, the rear end of the /4 flannel 10 is set low, and the thickness of the arm and dowel material a in this part is made maximum,
By reducing the thickness of the front and rear parts and using nine or more pieces of material depending on the body pressure distribution, less material can be used effectively. Therefore, it is possible to reduce the cost (by saving the amount of wood used).

In addition, since the spring locking portion 5 is configured to lock the locking end 6a of the tension spring 6 in the hole that has been closed and subjected to purling processing, the locking end 6a of the tension spring 6 is locked. ! &p is smooth and effective in preventing wear and deformation due to load. Since the position of the puffer hole can be set freely, the initial repulsion force at the time of installation can be changed as appropriate even if all the parts are of the same standard or the tension springs 6 are used. Since the amount and shape of deflection of the flannel 3 can be adjusted, body pressure distribution can be adjusted even more easily.

In addition, the spring locking part 5...is not limited to the purling hole, but also has a cut-and-raised hole as shown in Fig. 4, or a part to be hooked between multiple holes as shown in Fig. 5. It may be something. Further, the locking end 61 of the spring may be hooked not only in the hole but also in a cut-and-raised lug, for example.

FIG. 6 shows a car seat showing another embodiment of the present invention. Since the basic configuration is the same as that of the above embodiment, common parts are given the same reference numerals and explanations will be omitted, and different parts will be omitted. Only the /# of this example will be explained below.
The flannel 3 has an upwardly bent portion 8C over its entire circumference and has a dish-like shape with a concave central portion, and spring locking portions 5 are formed as tubes on both left and right sides of the flannel 3 to provide a tension spring. 6
... is locked. That is, in this example, a4
It is supported by springs 6 on both left and right sides of the panel 3. With this configuration, as in the previous embodiment, the elasticity of the /f material 80 and the deflection and tension of the panel S are Good body pressure distribution can be obtained by combining the elastic forces of the springs 6, and the structure is simple and easy to manufacture.

It goes without saying that the present invention can be applied to seats of vehicles other than automobiles. In addition, when carrying out the present invention, frames, panels, spring locking parts, pull-outs, etc. shall be used without departing from the gist of the present invention. Il? ) spring, /4. It goes without saying that the specific shape, structure, arrangement, etc. of the material group can be modified in various ways other than the above-described embodiments.

As described above, the present invention has the great effect of making it possible to manufacture a comfortable seat at a low cost by employing pad material, mother flannel, tension springs, and the like.
