2. Description of the Related Art A conventional automobile seat slide is fixed to a floor side through a mounting bracket, and has a substantially U-shaped lower rail having an opening formed in the upper portion along the longitudinal direction.
By fitting a base piece that is fixed to the seat side and extends upward from the opening of the lower rail and an upper rail that has a lower portion that slidably fits through the balls and rollers in the lower rail, the seat moves forward and backward. It can be moved. (See, for example, JP-A-62-238136)

However, in the conventional seat slide as described above, particularly when the seat is moved to the frontmost position, the rear end of the lower rail is exposed on the rear seat floor,
It looks bad, and when the seat moves backwards and the lower part of the upper rail projects from the end of the lower rail, dust adheres to the upper surface of the lower part of the upper rail, which is the sliding surface, There are problems such as adversely affecting the sliding of the upper rail.

[0004]

SUMMARY OF THE INVENTION In view of the above problems of the prior art, the present invention removes dust adhering to the upper rails by moving the upper rails to maintain smooth sliding. It is also an object of the present invention to provide a protective cover for an automobile seat slide, which is improved in appearance and safety by covering the end portion of the lower rail.

[0005]

In order to achieve the above object, the device of the present invention comprises a substantially U-shaped lower rail fixed to the floor side and having a longitudinally oriented opening formed in the upper side thereof. An end portion of the lower rail in an automobile seat slide, which is slidably fitted to a base piece fixed to the lower rail and extending upward from the opening of the lower rail, and an upper rail having a lower portion fitted into the lower rail. The protective cover is characterized in that a tongue portion capable of sliding contact is provided on the upper surface of the lower portion of the upper rail.

[0006]

The protective cover for covering the end of the lower rail is provided with a tongue portion slidably in contact with the upper surface of the lower portion of the upper rail. When the seat moves forward from the position where the end of the upper rail protrudes rearward from the protective cover and moves so that it is stored in the protective cover, dust that adheres to the upper surface of the lower part of the upper rail is moved. As the upper rail moves forward, the tongue slides on the upper surface of the lower part of the upper rail and is removed by the tongue.Therefore, the tongue moves into the lower rail and slides between the upper rail and the lower rail. It is possible to always maintain smooth sliding without adhering to the moving surface.
