Description

[Detailed Description of the Invention] The present invention relates to an improvement of a vehicle (automobile) seat in which a cushion body made of a foam material is placed on a saucer-shaped seat base.

Conventionally, this type of general seat has a seat b and a cushion body a, as shown in FIGS. It had a structure in which the velvet type fastener 5 was engaged with and fixed to one side of the fastener 5.

Therefore, the fixing points of both cannot be seen from the outside, making it impossible to check (inspect) how well they are fixed, and the fixing points may become damaged and come off after long-term use.

In addition, some conventional products are provided with an engaging part on the cushion body a side and a locking member on the seat b side that engages and locks with the locking part of the cushion body a (for example, in actual use). (Japanese Patent Publication No. 55-163869), since the locking member is fixed to the seat and protrudes toward the inside of the cushion body, there is a problem that the elasticity of the cushion body a is impaired. That is, this is because the deflection of the cushion body is regulated by the locking member protruding from the seat side.

Therefore, the purpose of this invention is to eliminate such defects in conventional products, and the gist of the invention is to provide a vehicle seat in which a cushion body made of foam material is placed on a saucer-shaped seat base. In addition to embedding and fixing a frame line in the bottom of the cushion body,
A hanging plate having a length exposed from the bottom surface of the seat is vertically disposed on the frame line, and a locking hole into which the hanging plate penetrates is opened in the seat, and the locking hole is The cushion body is fixed to the seat by inserting the above-mentioned latching plate into the seat and hooking the ends of the latching plate to the outer surface of the seat.

Therefore, when the cushion body bends under the load, the retaining plate projects downward from the bottom surface of the seat, and the deflection of the cushion body is not restricted. Further, since the cushion body is prevented from escaping upward by the end of the latching plate that is hooked to the bottom surface of the seat, the cushion body does not come off from the seat.

Embodiments of the present invention will be explained below based on FIGS. 3 to 11. FIGS. 3 to 7 show the first embodiment, and a in the figure shows the elasticity used in conventionally known seats. A cushion body made of foam material having
A metal frame line 1 bent into an annular shape is embedded in the bottom of the cushion body a, and hanging plates formed by bending a flat plate made of a metal material into a U-shape are installed on the front, back, left and right sides of this frame line 1. 2, 2, . . . are buried so that both their tips are exposed to the outside from the bottom surface of the cushion body a. Then, this exposed portion is used as the hooking portion 21, 21, and the hooking portion 21, 21 is
is made of a material that is thick enough to be bent with your fingertips.

As described above, the frame line 1 embedded in the cushion body a and the U-shaped hanging plates 2, 2, which are vertically disposed on the frame line 1, are formed by foam-molding the cushion body a. At the same time, it is embedded and fixed integrally in the bottom of the base. The hanging plates 2, 2, . . . are fixed by welding by hooking the frame line 1 onto the curved hooking portions 22 thereof.

b in the figure is a seat made of reinforced plastic (FRP) or a metal plate formed into a saucer shape, on the upper surface of which the cushion body a is placed and fixed, and the bottom surface of the cushion body a of this seat b is A slit-shaped locking hole 3, 3... is formed at a position where the locking plate 2, 2, . ...Latching part 2
1 and 21 so as to be able to protrude to the back surface of seat b.

Thus, when the cushion body a is placed on the seat b, the locking plates 2, 2, . . . of the cushion body a are inserted into the locking holes 3, 3, . Therefore, when the externally protruding latching parts 21, 21 are respectively bent outward and the latching parts 21, 21 are hooked to the bottom surface of the seat b, the elasticity of the cushion body a causes the latching plates 2, 2... ... is securely attached and fixed to seat b (Figures 6 and 7).

c is the epidermis that covers the cushion body a.

8 and 9 show a second embodiment, in which when the cushion body a is foam-molded, the cushion body a
The hook portions 22 of the above-mentioned hanging plates 2, 2, etc. are hooked and hung vertically on a frame line 1 which is embedded and fixed integrally in the bottom of the cushion body a, and the hanging plates 2, 2, etc. are hung on the bottom of the cushion body a. 2... to the frame line 1 so that it can be hung 4,
4... is provided.

The third embodiment shown in FIGS. 10 and 11 uses U-shaped hanging plates 2', 2'... made of spring material. '... are provided with arrow-shaped hooking parts 21', 21' at both ends of the seat b, so that they can be easily inserted into the locking holes 3, 3... of the seat b,
It is designed so that it can be hung without bending as in the previous embodiment (Fig. 11). It is preferable that this hanging plate 2' be molded from a hard synthetic resin material to prevent abnormal noise from coming into contact with the seat b.

As described above, the present invention allows the attachment and fixing points between the cushion body and the seat to be seen from the outside, making it easy to check the degree of fixation and preventing the production of defective products. Moreover, when the cushion body bends under the load, the catch plate provided on the cushion body protrudes to the outside of the seat, so that the bending of the cushion body is not restricted by the catch plate. Therefore, there is no feeling of a foreign body due to the hanging plate, and seating comfort is improved.

In addition, the locking plate, which is embedded and fixed inside the cushion body through the frame line, is inserted and fixed into the locking hole drilled in the seat, so the fixed point will not come off even after long-term use, unlike conventional products. Both can be fixed.

Furthermore, since the bottom of the cushion body made of foam material is fixed to the seat base by a hooking plate, it is possible to prevent the cushion body from moving in the front, back, left and right directions, thereby providing a vehicle seat that is extremely comfortable to sit on. I can do it.

Thus, the intended purpose can be achieved.
