Abstract

A release device for the upper rail and the lower rail of a longitudinal seat adjustment system of a motor vehicle seat, the release device having a lever rotatably supported on the upper rail of the seat. An end of the lever interacts with the locking means and optionally releases the locking means. A handle is provided at the other end. If the handle is operated, the lever moves relative to the upper rail from a passive position to a release position and moves the locking means from a locking position to a releasing position. So the release device automatically moves into a passive position of the release device, a spring element is provided, which preloads the lever into the passive position of the lever. The spring element additionally supports the lever on the upper rail.

Dependent claims

A release device which has a lever, a handle being provided at one end thereof and the other end thereof cooperating with a locking means,

wherein the release device has a spring means which pretensions the lever into a passive position thereof;
wherein the spring means is adapted to fasten and mount in a rotatable manner the lever to an upper rail of a motor vehicle seat;
wherein a latching fastening means is provided between the handle and the lever, wherein the latching fastening means is designed such that the handle is released from the lever when the handle is inappropriately actuated by a rotation in a direction towards a lower rail;
wherein the latching fastening means is then released from the lever so that the lever is undamaged;
and
wherein spring means is designed such that the spring means returns at least one of the handle or the latching fastening means into its original position as soon as an inappropriate loading is no longer applied to the lever;
and
wherein the spring means is a leg spring which is produced from a wire, being designed such that the wire passes through both a recess in the lever and a recess in the upper rail.
