DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bracket mounting structure for a seat slide rail.

[0002]

2. Description of the Related Art In general, a seat slide rail includes an upper rail and a lower rail, and the upper rail is fixed to a seat side. The lower rail is supported by front and rear brackets attached to the vehicle body floor side.

[0003] The rear bracket is located at the foot of the rear occupant, and a means for attaching a cover from a place where the bracket is caught or has a poor appearance is disclosed in, for example, Japanese Utility Model Publication No. 6-22603.

[0004] The cover is formed of a synthetic resin, has an engagement claw inside, and is attached by engaging the engagement claw with a leg serving as a bracket.

[0005]

As described above, the cover is always located at a position where it is easily kicked off by the rear occupant, the attachment is made by the engagement claws, and the cover is made of synthetic resin whose material is easily deformed. Therefore, there is a problem that the engaging claw is easily broken, cracked, and detached when it is repeatedly kicked off with aging or a foot.

In this case, means for attaching the cover by screwing is also conceivable, but this increases the number of steps and is not desirable in terms of the number of assembly steps.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a seat slide rail bracket cover mounting structure capable of obtaining a reliable mounting state for a long period of time without using means such as screws.

[0008]

In order to achieve the above object, the present invention is directed to a seat slide rail supported by front and rear brackets having a lower end attached to a vehicle body floor, and a surface and both side surfaces of the bracket. An entire body is covered with a bracket cover, and an engaging body that engages with the bracket is provided on an inner portion of the bracket cover. At a lower end of the bracket cover, a vertical flange portion facing a recess of the vehicle body floor, And a horizontal flange portion.

[0009]

According to this bracket cover mounting structure, the lower end of the bracket cover, which is most likely to be kicked off and subjected to an impact load, has a wide area vertical flange facing the recess of the vehicle body floor and the upper surface of the vehicle body floor. Since the load is received by the horizontal flange portion having a large area on which it is mounted, the holding ability of the lower end portion of the bracket cover is not weakened, and a reliable mounting state can be obtained for a long period of time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be specifically described below with reference to FIGS.

In FIG. 1, reference numeral 1 denotes a seat slide rail, which comprises a lower rail 3 and an upper rail 5. The upper rail 5 is opposed to the lower rail 3 by left and right guide rollers 7, 7 and a center support roller 9. It is movably supported.

The upper rail 5 can be attached to a seat (not shown).

The lower rail 3 includes front and rear brackets 11.
(The front side is not shown), and a bracket cover 13 is attached to the rear bracket 11.

The bracket 11 has an upper end portion 17 and a lower end portion 19 which are bent substantially horizontally from the inclined main body portion 15 as shown in FIG. 5, and on both sides, each of the lower end portion 19 to the main body portion 15 is provided. Reinforcing ribs 21 and 21 that are continuous in the longitudinal direction over the region are provided. The upper end 17 of the bracket 11 is fixed to the end of the lower rail 3 by rivets or welding. The lower end 19 of the bracket 11 is disposed in a recess 25 of the vehicle body floor 23 as shown in FIG.
A bolt 29 and a nut 30 are attached to the burred mounting portion 27.
Thus, it is fixedly supported in the recess 25 of the vehicle body floor 23.

The concave portion 25 of the vehicle body floor 23 is set to a depth H at which the lower end portion 19 of the bracket 11 does not protrude from the floor surface 23a of the vehicle body floor 23, so that a feeling of protrusion does not occur.

On the other hand, the bracket cover 13 attached to the rear bracket 11 is made of a synthetic resin material, and has a surface 11a, both side surfaces 11b, 11b of the bracket 11.
b and a U-shaped cross section that covers the entire recess 25 of the vehicle body floor 23.

Inside the upper end of the bracket cover 13,
The first engaging body 27 engaging with the edge 17a of the upper end 17 of the bracket 11 and the second engaging body 29 engaging with the edge 15a of the main body 15 of the bracket 11 are respectively left and right. A pair is provided.

At the lower end of the bracket cover 13, a front wall surface 25a and a rear wall surface 25b of the concave portion 25 of the vehicle body floor 23 are provided.
Vertical flange 3 before and after wide surface contact with each other
1, 31 and a horizontal flange portion 33 that is placed on the floor surface 23a of the vehicle body floor 23 are provided.

The bracket cover 1 thus configured
According to the mounting structure of No. 3, the lower end portion 19 of the bracket 11
Is accommodated in the concave portion 25, and the entire concave portion 25 is covered by the horizontal flange portion 33, so that a flat feeling without the lower end portion 19 protruding from the vehicle body floor 23 can be obtained.

The lower end of the bracket cover 13 which is most likely to be kicked off has a vertical flange portion 31 having a large area.
Since the impact load is received by the horizontal flange portion 33 and the horizontal flange portion 33, the holding property is not weakened, and a reliable mounting state can be obtained for a long period of time.

[0021]

As described above, according to the present invention, the lower end of the bracket cover which is most likely to be kicked off is
The impact load can be received by the vertical flange portion facing the concave portion and the horizontal flange portion placed on the floor surface of the vehicle body floor, so that a reliable mounting state can be ensured for a long period of time.
