Abstract

A sliding rail guide arrangement having a locking device for a vehicle seat comprises an outer rail of C-shaped configuration and an inner rail guided displaceably in the outer rail. The locking device comprises a locking lever which is mounted on a mounting member carried on the outside of the outer rail, and the lever carries a locking portion to lock the inner rail with respect to the outer rail. The locking portion, in the locking position, extends through an access aperture in the outer rail and engages into a respective selected locking opening in the inner rail.

Claims

1. A sliding rail guide arrangement with locking device for a vehicle seat, comprising an outer rail of substantially C-shaped configuration including at least one substantially C-shaped end portion having at lest one aperture formed therein, an inner rail guided in the outer rail slidably therein and having a plurality of locking openings formed therein, a locking lever having at least one locking portion thereon, mounting means including a base portion having first and second ends and first and second limb portions which project away from the respective ends of the base portion in the same direction relative thereto, at least one of said limb portions of said mounting means having a mounting opening therethrough and a portion of said locking lever disposed in said mounting opening for mounting said lever on said mounting means movable relative thereto between a first position in which said inner and outer rails are locked relative to each other and a second position permitting relative sliding movement of said inner and outer rails, said base portion of said mounting means mounted to said outer rail and having at least one aperture aligned with said at least one aperture in said substantially C-shaped end portion of said outer rail and said locking portion on said locking lever positioned to extend through said aperture in said base portion of said mounting means and through said at least one aperture in said outer rail to engage into a respective one of said locking openings formed in said inner rail to lock said inner rail in said outer rail in said first position of said locking lever.

2. An arrangement as set forth in claim 1 wherein each said limb portion of said mounting means has an opening therein and said lever is mounted in said openings, and further including a spring means acting on said lever to urge it towards said first position thereof whereby said lever is pivotable laterally away from said outer rail when it is moved from said first position to said second position, against the force of said spring means.

3. An arrangement as set forth in claim 1 and further including a spring means adapted to mount said lever in a said opening in one of said limb portions of said mounting means whereby said lever is pivotable in a vertical direction laterally beside said outer rail when it is moved between said first and second positions thereof, said spring means urging said lever towards said first position.

4. An arrangement as set forth in claim 1 wherein each said limb portion of said mounting means has an opening therein and further including a spring means adapted to mount said lever in said openings in said limb portions of said mounting means whereby said lever is pivotable about a longitudinal axis thereof extending in parallel relationship to said outer rail, when it moves between said first and second positions thereof, said spring means urging said lever towards said first position thereof.
