Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a support structure for an automobile seat that allows the seat to be easily assembled to a rail member.

(Prior Art) An automobile seat is sometimes supported on the floor of a vehicle interior so as to be movable back and forth for ease of getting in and out of the vehicle interior.

For example, the means for supporting the seat on the floor is configured as follows.

That is, a rail member having a substantially C-shaped cross section is provided on the vehicle interior floor and extends in the longitudinal direction of the vehicle body. On the other hand, a slide piece that is fitted into this rail member so as to be slidable back and forth is provided, and the seat is supported by this slide piece (for example,
Publication No.).

(Problem to be solved by the invention) By the way, when assembling the seat to the rail member on the floor, when trying to fit the slide piece into the rail member, the above configuration requires the following procedure. .

That is, the seat is once positioned in front of the rail member. Next, from this state, the slide piece is inserted into the front end of the rail member. Then, the slide piece is slid to move the seat backward. This completes the assembly of the seat to the rail member.

However, the assembly work described above requires the seat to be moved back and forth significantly, and the work to fit the slide piece into the front end of the rail member is complicated because the seat is not positioned and is unstable. be.

(Purpose of the invention) This invention was made in view of the above-mentioned circumstances, and aims to provide a support structure for an automobile seat that allows the seat to be easily assembled to a rail member.

(Structure of the device) The feature of this device for achieving the above object is that a pair of front and rear notches are provided at the front of the rail member to allow the front and rear slide pieces to pass through and to fit these slide pieces into the rail member. This is because the front slide piece is formed on the upper part and configured so that the front slide piece cannot pass through the rear notch.

(Example) Hereinafter, an example of this invention will be described with reference to the drawings.

Reference numeral 1 denotes a vehicle interior floor of an automobile, and a center tunnel 2 is formed in the center of the floor 1 in the vehicle width direction. Additionally, side sills 3 are installed at the ends of the same floor 1 as above.
is provided. A door opening 4 is formed above the side sill 3, and a door 5 is provided to open and close the door opening 4.

A seat 7 is supported on one side of the floor 1 in the vehicle width direction via a rail member 6 extending in the longitudinal direction of the vehicle body so as to be movable back and forth. This seat 7 is composed of a seat cushion 7a and a seat back 7b.

The rail member 6 is composed of an inner fixed rail 10 supported on the side wall of the center tunnel 2 via a bracket 8, and an outer fixed rail 11 supported on the side sill 3 and having a substantially C-shaped cross section.

A movable rail 12 is placed on the inner fixed rail 10.
will be provided. A plurality of rollers 13 are interposed between the inner fixed rail 10 and the movable rail 12 over the entire length of the inner fixed rail 10 in the front-rear direction. The rolling of the rollers 13 allows the movable rail 12 to move freely back and forth along the longitudinal direction of the inner fixed rail 10. The above movable rail 12
Connectors 15 and 1 are connected to at least two locations at the front and rear of the inner side of the seat cushion 7a in the vehicle width direction.
Supported through 5.

On the other hand, the rear portion of the seat cushion 7a on the outer side in the vehicle width direction is supported by the outer fixed rail 11 via a support arm 16 so as to be movable back and forth.

The support arm 16 includes a sheet metal arm body 17 protruding diagonally downward from the end of the lower surface of the seat cushion 7a, a pair of front and rear resin slide pieces 19 attached to the protruding ends of the arm body 17, 20, and each slide piece 19, 20 is slidably fitted into the outer fixed rail 11.

Although not shown, the seat 7 is provided with a locking means for releasably locking the seat 7 to the floor at a desired position.

A pair of front and rear notches 22 and 23 are formed in the front upper part of the outer fixed rail 11, and these notches 2
2 and 23 pass through the front and rear slide pieces 19 and 20, respectively, and the slide pieces 19,
20 can be fitted into the inner fixed rail 10.

Further, in the above case, the dimension of the rear slide piece 20 in the longitudinal direction is formed to be smaller than that of the front slide piece 19. The longitudinal dimension l of the rear notch 23 is the front slide piece 19.
This is smaller than the dimension L in the same direction of the front slide piece 19, thereby preventing the front slide piece 19 from passing through the rear notch 23.

In the above configuration, a procedure for assembling the seat 7 to the rail member 6 will be explained.

First, the movable rail 12 with the inner fixed rail 10 assembled in advance is attached to the lower surface of the seat cushion 7a of the seat 7, and then this seat 7 is attached to the floor 1.
It is located above the front part of the upper outer fixed rail 11 (as shown by the chain double-dashed line in FIG. 1).

Next, lower the seat 7 and insert the front and rear slide pieces 1.
9 and 20 are brought into contact with the upper surface of the outer fixed rail 11,
By sliding on this surface, the front and rear notches 22,
Pass 23. Then, the front and rear slide pieces 19 and 20 are automatically fitted into the outer fixed rail 11. Then, from this state, the seat 7 is moved rearward. On the other hand, if the inner fixed rail 10 is screwed to the floor 1 side, the assembly of the seat 7 to the rail member 6 is completed.

In the above case, even if the front slide piece 19 slides rearward within the outer fixed rail 11 from this front end side and moves the position of the rear notch 23, the longitudinal dimension l of the rear notch 23 is Front slide piece 19
Since the front slide piece 19 is smaller than the dimension L in the same direction, the front slide piece 19 is prevented from passing through the rear notch 23 and unexpectedly coming out from the outer fixed rail 11. Therefore, after the front and rear slide pieces 19 and 20 are fitted into the outer fixed rail 11, the seat 7 can be moved and adjusted until the front slide piece 19 is located near the rear of the front notch 22.

(Effect of the invention) According to this invention, a pair of front and rear notches are formed in the front upper part of the rail member to allow the front and rear slide pieces to pass through and to fit these slide pieces into the rail member, and the front slide piece is inserted into the rear part of the rail member. Since the seat is configured so that it cannot pass through the notch, when assembling the seat to the rail member, the seat is first positioned above the front of the rail member, and then the weight of the seat is temporarily placed on the rail member. By passing the front and rear slide pieces through the front and rear notches and moving the seat rearward from this state, insertion of both slide pieces is completed.

Therefore, when assembling the seat, there is no need for a large forward movement of the seat to once position the seat in front of the rail member as in the conventional art. In addition, when fitting the slide piece into the rail member, the weight of the seat can be temporarily placed on the rail member, which eliminates the trouble of fitting the slide piece into the rail member with the seat in an unstable state. Therefore, the seat can be easily assembled to the rail member.
