Description

[Detailed Description of the Invention] The present invention relates to an improvement in a mounting structure for assembling a vehicle seat such as an automobile to a vehicle body side.

The seat was developed in 1986 as a seat that could be easily assembled and removed from the vehicle body without the need for tools.
The one described in Japanese Patent No.-36530 and the one shown in FIG. 1 have already been disclosed. All of these have a structure in which a flat plate-shaped locking plate 10 fixed to the seat is horizontally inserted into and engaged with a groove 11a of a holder 11 fixed on the vehicle floor (FIG. 1A and B).
In the figure, 10a indicates a holder insertion hole provided in the locking plate 10, and 10b, 10b, and 10b indicate seat frames to which the locking plate 10 is fixed.

Therefore, in conventional products with such a structure, the seat moves forward and backward due to the load when the vehicle suddenly stops or starts, so the engagement between the locking plate 10 and the holder 11 is released and the seat is removed. Therefore, in order to eliminate such problems, it was necessary to install a large number of fixtures such as locking plates and holders on the seats and the vehicle floor.

The present invention was developed in view of these circumstances, and its basic structure is to engage a locking member with a hook-shaped stopper with a holder to prevent the seat from coming off when the vehicle suddenly stops or starts. When the stopper is engaged with the holder, due to the elasticity of the cushion member,
This is to prevent the engaged state from being released.

Embodiments of the present invention will be described below with reference to FIGS. 2 to 5.

In the figure, a is a holder that is fixed upright on the vehicle floor located on the bottom of the front part of the Seatro, b is a locking member that is fixed to the bottom of the Seatro and allows holder B to be inserted into it, and c is a holder that is laid on the vehicle floor. The cushion members that spring the locking members upward are shown respectively. Note that the seatro is composed of seat frames 2, 2... made of wire rods, a foam material, and a skin member that covers these.

The holder a is made of a metal or synthetic resin plate having a predetermined rigidity, and has wing-shaped fixing parts a 1 , a 1 that are fixed to the vehicle floor A with screws ₁ , ₁ , and a mountain-shaped part integrally formed on the fixing parts a ₁ , a _{1 .} consists of subjects a ₂ and subjects a ₂
is bent into a mountain shape in the vehicle width direction, and its main body is a ₂
At the lower end of the rear side of the seatro, there is provided an insertion part _a3 cut out horizontally and a locking part _a4 cut out at right angles above the tip of the insertion part _a3 .

Further, a cushion member c, such as an elastic insulation material such as a nonwoven fabric or a foam sheet, and a silencer are laid on the vehicle floor i on which the holder a is fixed in an upright position.

The locking member b is Seatro's seat frame 2,
2, 2 is a metal plate (Fig. 4) welded to the metal plate, and a recessed part _b1 provided in the center of the metal plate creates a space for inserting the holder above the locking member b,
A fitting b ₂ having a slightly larger diameter than the planar shape of the holder b is provided in the recess b ₁ . A hook-shaped stopper _b3 whose tip is bent upward extends from the rear side mouth edge of this insertion hole _b2 . The height h of the bent end of the above stop b ₃ is holder a
The insertion part a is formed higher than the gap w of _{the 3} (Fig. 5).

In this way, to install the Seatro on the car floor, first insert the holder a of the car floor into the locking member b provided at the bottom of the Seatro, and then push the Seatro against the elastic force of the cushion member c. While pressing down, the stopper
Insert b ₃ from the insertion part a ₃ of the holder a and engage it with the locking part a ₄ to fix it to the front part of the Seatro.

In the Seatro fixed on the vehicle floor A, the cushion member c always pushes up the stopper _b3 of the locking member b, so the stopper _b3 does not escape from the locking part _a4 of the holder a. . Moreover, since the seat frames 2, 2 shown in the figure are formed by bending wire rods, when the seat rod is pressed and fixed to the vehicle floor, the seat frames 2, 2 exert elasticity in the vertical direction, and the stopper b ₃ It never comes off.

Note that the rear part of the seatro is fixed by a seat buckle (Figure 2).

The mounting structure of the vehicle seat according to the present invention includes a holder that is fixed upright on the vehicle floor, a locking member that is fixed to the bottom of the seat and into which the holder is fitted, and a cushion member that is installed on the vehicle floor and springs the locking member upward. The holder consists of a main body bent into a mountain shape in the vehicle width direction, an insertion part cut horizontally at the lower end of one side of the main body in the longitudinal direction of the seat, and a cutout above the tip of the insertion part. The locking member includes a fitting hole into which the holder is inserted, and a hook-shaped stopper extending on the edge of the fitting hole and engaging with the insertion portion and the locking portion of the holder. Therefore, the stopper of the locking member that is inserted into and engaged with the locking portion from the insertion portion of the holder is always resiliently held in the engaged state by the cushion member. Since the stopper is hook-shaped, the engaged state will not be released due to longitudinal and vertical loads applied to the seat. Therefore, the seat can be installed securely and there is no risk of it coming off, so there is no need to provide a large number of mounting members between the seat and the vehicle floor as in conventional products, and the seat has the advantage of being easy to assemble to the vehicle body. be.

Thus, achieving the intended purpose.
