Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat cushion having a small number of parts and easy to assemble.

[0002]

2. Description of the Related Art Conventionally, in seat cushions for automobiles, forklifts and the like, vehicle seat cushions in which a cushion pad in which a frame-shaped insert wire is embedded and integrated at the bottom is mounted on a seat frame and fixed are widely used. It is used. In this case, in order to fix the cushion pad to the seat frame, a mounting plate with a screw hole at the required location of the insert wire is welded so as to project outward from the bottom of the insert wire, and the seat is A small screw or the like is screwed in from the frame side to fasten and fix.

However, in the above-mentioned conventional apparatus, since the mounting plate is welded to the insert wire, the number of parts is increased and the welding operation is complicated.
There was a problem that the production cost was high. Further, as described above, since the mounting plate is projected outward from the bottom of the insert wire, the insert wire is buried at a position considerably inside the outer periphery of the cushion pad. However, there is also a problem that a sufficient outer shape holding function cannot be exhibited.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems in the prior art, and can reduce the number of parts and production cost. It is possible to omit troublesome steps such as improving the workability, and furthermore, the insert wire can be buried at a position close to the outer periphery of the cushion pad so that the insert wire can exhibit a sufficient outer shape holding function. It has been completed for the purpose of providing a vehicle seat cushion that can be used.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a vehicle seat cushion according to the present invention has a cushion pad in which a frame-shaped insert wire is buried and integrated at the bottom, and is mounted on a seat frame. In the fixed vehicle seat cushion, the insert wire is provided with a flat plate portion for fixation in which a wire material is partially flattened and a screw hole is formed in the wire material, and the cushion pad is provided. The seat frame is fastened and fixed to the seat frame by screws which are screwed into the screw holes from the seat frame side.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of the present invention applied to a seat cushion of a forklift will be described in detail with reference to the drawings. In the figure, 1 is a cushion pad formed by foaming so that a frame-shaped insert wire 3 is embedded and integrated at the bottom, 2 is a pipe-shaped seat frame, and 4 is a decoration mounted so that the outside of the seat frame 2 is covered. The garnish is basically the same as the conventional vehicle seat cushion in that the above components are fixed around the seat frame 2.

As shown in FIG. 2, the insert wire 3 is formed by bending a wire material so that a plurality of high step portions 3d for increasing the embedding strength and a low step portion 3c for fixing are continuously provided. In each fixing low step portion 3c, a fixing flat plate portion 3a having a screw hole 3b formed by partially pressing and flattening a wire material and forming a hole is formed. On the other hand, the above-mentioned seat frame 2 is provided with a screw insertion hole corresponding to a screw hole 3b provided in the flat plate portion 3a for fixing the insert wire 3 outward from the bottom of the pipe material bent in a U-shape. A bracket 2a with a hole is provided outward, and the screw 5 is screwed into the screw hole 3b from the screw insertion hole of the bracket 2a. A screw insertion hole 4b corresponding to the screw hole 3b is formed in the lower flange 4a for mounting the seat frame 2 of the garnish 4 described above.

As shown in FIG. 3, a cushion pad 1 is placed on a seat frame 2 and a garnish 4 is arranged below the cushion pad 1. As shown in FIG. 2b, the screw hole 3b of the insert wire 3 and the mounting hole 4b of the garnish 4, and the screw 5 is moved from the screw hole 4b of the garnish 4 to the screw hole 2b of the bracket 2a.
Screwed into the screw hole 3b of the insert wire 3 to secure the seat cushion in which the cushion pad 1, the seat frame 2, and the garnish 4 covering the outside of the seat frame 2 are firmly integrated. Obtainable.

As described above, according to the present invention, the insert wire 3 and the seat frame 2 can be directly fastened to each other. Since there is no need to weld so as to project outward from the bottom of the insert wire, the number of parts is small and the assembling work can be performed easily. In addition, the insert wire 3 can be buried in a position close to the outer periphery of the cushion pad 1 as much as there is no mounting plate that protrudes outward as in the related art, so that a sufficient outer shape holding function can be exhibited and dimensional accuracy is excellent. As a result, the occurrence of a gap with the garnish 4 can be accurately prevented.

The insert wire 3 is formed by bending a wire material so that a low step portion 3c for fixing is connected to a plurality of high step portions 3d for enhancing the embedding strength, and the screw holes 3b are formed. If the fixing flat portion 3a is formed in the low step portion 3c, the sense of unity with the cushion pad 1 is further enhanced by the plurality of high step portions 3d, so that a high quality product can be obtained. The outside of the seat frame 2 is covered with a garnish 4 in which a screw insertion hole 4b is provided in the lower flange 4a, and the screw 5 is screwed from the screw insertion hole 4b of the garnish 4 through the screw insertion hole 2b of the bracket 2a. When screwing into the hole 3b,
Since the seat frame 2 is not exposed to the outside, the appearance is good.

[0011]

As is apparent from the above description, according to the present invention, a flat plate portion for fixing a wire material partially flattened at the bottom of a cushion pad and having a screw hole formed therein is provided at a required position. Since the frame-shaped insert wires provided are embedded and integrated, they can be directly fixed to the seat frame, and the number of parts can be reduced and troublesome processes such as welding work can be omitted, producing The cost can be reduced, the assembly is easy and the workability can be improved, and the insert wire can be buried near the outer periphery of the cushion pad, so it has a sufficient external holding function. There are various advantages, such as being able to do so. Therefore, the present invention greatly contributes to industrial development as a vehicle seat cushion that has eliminated the conventional problems.
