Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat slide device capable of reliably attaching a support member for supporting an operation rod for seat slide adjustment.

[0002]

2. Description of the Related Art An outline of an automobile seat slide device is as follows.
A lower rail fixed to the vehicle body side, an upper rail fixed to the seat side and slidably engaged with the lower rail, a latch mechanism for restraining the movement of the upper rail with respect to the lower rail when meshing, and a latch mechanism Has an operating rod for releasing the engagement of the latch mechanism, and by releasing the engagement of the latch mechanism by operating the operating rod, it is possible to adjust the upper rail, that is, the seat forward and backward.

[0003]

The operating rod for releasing the meshing of the latch mechanism is supported by a supporting member fixed to the upper rail side, and the supporting structure thereof is, for example, Japanese Utility Model Laid-Open No. 3-81135. There is a means.

As shown in FIG. 14, this means fixes the mounting portion 105 of the support member 103 which rises vertically to the vertical vertical wall of the upper rail 101 by means of rivets. It is necessary to temporarily support it so that it will not move, and the mounting work is extremely troublesome because of the nerves involved in positioning during mounting. Further, as shown in FIG. 15, when a large load is applied to the supporting member 103 via the operating rod 109, the supporting member 10 may be changed in some cases.
3 may rotate in the direction of the arrow around the rivet 107, and in order to prevent this, it is necessary to make the rivet 107 itself large enough to have a sufficient fastening force.

Further, as shown in Japanese Utility Model Laid-Open No. 52-166220, an engaging hole for positioning is provided on one of the upper rail side and the supporting member side, and an engaging portion for engaging with the engaging hole is provided on the other side. Then, the support member can be rotated, but on the other hand,
Machining of the engaging hole and the engaging portion becomes troublesome, which is not desirable in terms of workability. Further, when the width is narrow like the support member 103 of Japanese Utility Model Laid-Open No. 3-81135, there are cases in which it is difficult to process the engaging portion and the like and cannot be carried out.

Therefore, an object of the present invention is to provide a vehicle seat slide device which is excellent in workability and workability and can be securely attached with a supporting member without causing an increase in weight.

[0007]

In order to achieve the above object, the present invention provides a lower seal fixed to the vehicle body side and an upper rail fixed to the seat side and slidably engaged with the lower rail. A latch mechanism that restrains the movement of the upper rail with respect to the lower rail when meshing, an operating rod that releases the meshing of the latch mechanism by being operated, and a support member that is fixed to the upper rail and supports the operating rod. In a seat slide device including the above, the support member and the upper rail are fixed by one shaft member, while the upper rail side is brought into contact with the outer peripheral surface of the support member, and the movement of rotating around the shaft member is restricted. The regulating part is integrated.

According to such a vehicle seat slide device, if the outer peripheral surface of the support member is brought into contact with the upper rail side restricting portion, the temporarily positioned state is ensured.
If it is fixed by the shaft member, it can be securely and quickly attached without rotating.

Further, since the regulating portion is integrally formed on the upper rail side, it does not impair the workability and does not increase the weight.
