Abstract

PROBLEM TO BE SOLVED: To heighten the joining strength of a mounting bracket to a floor without increasing the number of part items as well as to make improvements in setting operability. SOLUTION: This mounting structure is so constituted that a mounting part 5b of a mounting bracket 5 attached tight to the end of a lower rail 1 is contacted with a longitudinal wall surface 3a o a floor 2, and then the mounting part 5b and this longitudinal wall surface 3a are clamped together through a clamping member 4 and thereby the lower rail 1 is made so as to be attached to the floor 2. In this case, a projection part 5d is installed in either of the vicinity of a hole part 5c into which the clamping member 4 in the mounting part 5b of the mounting bracket 5 is inserted, and a proper spot of the longitudinal wall surface 3b to be opposed to the former, and a recess part 3c in which the projecting part 5d is fitted in the longitudinal direction of the lower rail 1 free of slide motion, in the other side, respectively.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat slide mounting structure which is disposed between a vehicle seat and a floor and movably supports the seat.

[0002]

2. Description of the Related Art As shown in FIG. 5, a conventional seat slide device includes a lower rail fixed to a floor (101) of a vehicle.
(102) and the lower rail (10
2) The upper rail (103) fitted slidably in the front-rear direction of the vehicle, and rotatably supported by the upper rail (103), and disengaged from an engagement hole formed in the lower rail (102). The latch member (10
4).

[0003] The lower rail (102) is a metal mounting bracket fixed to the bottom surface of the front end of the lower rail (102) by welding.
(105) is brought into contact with the front surface of the cross member (106) which is fixed in the lateral direction of the floor (101) and serves also as a portion for securing the floor rigidity and fixing the seat slide device to the vehicle body. The front part is fixed to the floor (101) by fastening with a bolt (107) facing in the front-rear direction.

[0004]

However, in the case of a vehicle such as a leisure car having a seat installed at a high position,
To secure the underfloor height, the legs (105
a) must be lengthened vertically so that the lower rail (102) floats upward from the floor (101).

As a result, the distance between the bottom of the lower rail (102) and the fastening portion (107) becomes long, and when the seat is overloaded in the lateral direction, the bracket (105) is moved to the fastening portion. There is a problem in that the seat is pivoted laterally with the fulcrum (107) as a fulcrum, and the entire seat is likely to deviate from a normal position.

SUMMARY OF THE INVENTION In view of the above problems of the prior art, the present invention provides a seat slide for a vehicle in which the joining strength of the mounting bracket to the floor is increased and the mounting workability is improved without increasing the number of parts. It is intended to provide a mounting structure.

[0007]

SUMMARY OF THE INVENTION According to the present invention, there is provided a lower rail fixed to a floor, and an upper rail fixed to a seat and slidably fitted to the lower rail. A mounting bracket is fixed to an end of the lower rail in the vehicle seat slide, and the mounting portion of the mounting bracket is brought into contact with a vertical wall surface of the floor, and the mounting portion and the vertical wall surface are fastened with a fastening member, whereby the lower rail is fastened. In the mounting structure for a vehicle seat slide, the mounting portion of the mounting bracket has a protruding portion at one of a vicinity of a hole through which a fastening member is inserted and a key portion of a vertical wall surface facing the hole. And, on the other hand, providing a recess in which the protrusion fits slidably in the longitudinal direction of the lower rail.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings. 1 and 2 show a first embodiment of the present invention, wherein (A) shows a lower rail (1) and an upper rail (6).
And a seat slide including: The lower rail (1)
Lateral cross member fixed to the vehicle body floor (2)
(3) is fixed as follows with a fastening member (4), which is a bolt, with the longitudinal direction facing the front-rear direction of the vehicle.

That is, a metal mounting bracket (5) is fixed to the bottom surface of the front end of the lower rail (1) by welding. The mounting bracket (5) has a leg portion (5a) fixed to the bottom surface of the lower rail (1) and a mounting portion (5b) fixed to the vertical wall surface (3a) of the cross member (3). Department (5
b) a hole (5c) into which the fastening member (4) is inserted, and a hole
A protrusion (5d) is formed in the vicinity of the lateral direction of (5c) and extruded rearward in the longitudinal direction of the lower rail (1).

The upper rail (6) is fixed to the seat side and fitted to the lower rail (1) so as to be slidable in the front-rear direction.

[0011] On the vertical wall surface (3a) of the cross member (3),
A screw hole (3b) into which the fastening member (4) is screwed and a recess (3c) facing rearward into which the projection (5d) is fitted are formed. Projection (5
The mounting bracket (3) is a fastening member between the d) and the recess (3c).
When fixed to the cross member (3) by (4), FIG.
As shown in (1), the lower rails (1) are slidably fitted to each other in the longitudinal direction to prevent the mounting bracket (5) from rotating around the fastening member (4), thereby displacing the seat slide (A). Can be prevented.

Accordingly, the mounting bracket (5) can be firmly fixed to the cross member (3), and the strength can be improved. In addition, seat slide (A) is replaced with floor (2)
When fixing the slide (A), the seat slide (A) can be positioned by fitting the protrusion (5d) into the recess (3c).
The seat slide is easily and securely inserted by inserting the fastening member (4) into the hole (5c) and screwing it into the screw hole (3b).
(A) can be fixed to the floor (2).

FIGS. 3 and 4 show another embodiment of the present invention. In this embodiment, a pin (7) with a head (7a)
Is fixed to the mounting portion (3a) of the mounting bracket (3) to form a projection (5d). The pin (7) forming the projection (5d) fits into a hole (3d) forming a recess formed in the vertical wall surface (3a) of the cross member (3), thereby providing the same as in the previous embodiment. In addition, the mounting bracket (5) can be stopped and positioned. The other configurations are the same as those of the first embodiment, and thus the same reference numerals are given and the detailed description thereof is omitted.

In the above embodiment, the projection (5d) is provided on the mounting portion (5b) of the mounting bracket (5), and the vertical wall surface (3a) of the cross member (3) facing the projection is provided. Protrusion
Although there is a recess (3c) or a hole (3d) into which (5d) fits,
Conversely, the mounting portion (5b) may be provided with a component corresponding to the concave portion (3c) or the hole (3d), and the vertical wall surface (3a) may be provided with a component corresponding to the projection (5d).

[0015]

According to the present invention, the following effects can be obtained. (a) It is possible to strongly prevent the mounting bracket from rotating around the fastening member with a simple configuration without increasing the number of parts, and to increase the support strength of the mounting bracket.

(B) By fitting the protrusion into the recess,
Positioning during mounting of the seat slide can be easily performed, and mounting workability can be improved.
