DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile seat, and more particularly to a structure of a seat cushion.

[0002]

2. Description of the Related Art As this kind of technology, for example, as shown in FIG. 4 (see Japanese Utility Model Application Laid-Open No. 58-68147), an automobile seat 1 has a reinforcing member 3 projecting from a floor member 2 of a vehicle body. A seat cushion 6 having a concave portion 5 formed in the bottom portion 4 so as to be inserted into the inside and made of a flexible material, and a seat back 7 arranged at the rear of the seat cushion 6.

[0003]

However, in such an automobile seat 1, when the seat cushion 6 is seated on the seat cushion 6, the seat cushion 6 itself is bent by its own weight. Is prevented, the occupant is given a foreign object sensation in that portion, and improvement is desired. In addition, as shown in FIG. 5, when the seat back 7 is previously attached to the back panel 8 of the vehicle body, and then the seat cushion 6 is assembled in an assembling sequence, the upper end of the reinforcing member 3 and the seat are indicated by arrows. When trying to insert it between the lower end of the bag 7 and the lower end, the workability is poor because the concave portion 5 is small, and improvement is desired. Therefore, an object of the present invention is to provide a device that eliminates the feeling of a foreign object when an occupant is seated and improves the assemblability to a vehicle body.

[0004]

According to a first aspect of the present invention, there is provided a vehicle seat having a flexible member having a concave portion formed at a bottom portion for inserting a reinforcing member protruding from a floor member of a vehicle body into the flexible member. And a seat back disposed at the rear of the seat cushion, wherein the concave portion of the seat cushion has a front portion formed substantially vertically with respect to the bottom along the reinforcing member. A wall, and a slope formed from the upper end of the vertical wall toward the bottom surface so as to have a space behind the reinforcing member, and the slope is provided above the slope. A panel made of a strength member is embedded at a position separated from the surface along the slope. According to a second aspect of the present invention, there is provided an automobile seat according to the first aspect, wherein the panels are respectively arranged at left and right seating positions of a seat cushion.

[0005]

[Operation] According to this structure, the panel present under the occupant's buttocks at the time of seating eliminates foreign body sensation, and has a slope that has a space behind the reinforcing member after assembly, so that the seat can be easily assembled to a car. Can be improved.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to FIGS. 1 to 3, an automobile seat 1 is shown.
The reinforcing member 1 protruded from the floor member 2 by being fixed to the through hole 13 of the floor member 2 of the vehicle body with the screw 10.
The seat cushion 15 includes a concave portion 14 formed in the bottom portion 4 for inserting the seat cushion 1 therein, and is made of a flexible material. The seat back 7 is disposed at a rear portion of the seat cushion 15. The concave portion 14 of the seat cushion 15 includes a vertical wall 16 having a front portion formed substantially perpendicular to the bottom portion 4 along the reinforcing member 11, and an upper end portion 16 a of the vertical wall 16.
The slope portion 1 is formed in a slope shape toward the bottom surface 4 so as to have a space 18 behind the reinforcing member 11.
The upper part of the slope 17 is located at a position separated from the surface of the slope 17, that is, along the slope 17 with a member 15 a having a constant thickness on the surface of the slope 17. A strength member, for example, a panel 19 made of an iron plate material is embedded. The panels 19 are arranged at left and right seating positions of the seat cushion 15, respectively. According to this embodiment,
Panel 1 that is present under the occupant 20 when the occupant 20 is seated
Since the occupant 20 receives its own weight due to the surface pressure due to the surface pressure 9, the occupant 20 is not given a foreign substance sensation to the strength member 11 despite the presence of the strength member 11. Also, the reinforcing member 1 after assembly
In the concave portion 14 behind the slope 1, the slope portion 17 where the space 18 exists
As a result, the ease of assembling the seat 1 to the automobile can be improved.

[0007]

As described above, the automobile seat of the present invention has the following features.
The seat cushion includes a seat cushion made of a flexible material having a concave portion formed on the bottom so that a reinforcing member protruded from a floor member of the vehicle body is inserted therein, and a seat back disposed at a rear portion of the seat cushion. , The recess of the seat cushion,
A vertical wall having a front portion formed substantially vertically along the reinforcing member with respect to the bottom portion, and a slope formed from an upper end portion of the vertical wall toward the bottom surface to form a space behind the reinforcing member. And a panel made of a strength member embedded along the slope at a position separated from the surface of the slope at an upper portion of the slope. Since the panels are arranged at the left and right seating positions of the seat cushion, the panel present under the occupant's buttocks at the time of seating eliminates foreign-body sensation, and includes a slope portion having a space behind the reinforcing member after assembly. This has the practical effect of improving the ease of assembling the seat to the vehicle.
