Walk-in mechanism associated with seat track structure

摘要

In combination with a seat track structure including a movable track slidable on a stationary track, a handle shaft rotatably supported on the movable track, a lock plate secured to the stationary track, and a detent lever secured to the hand shaft and being loaded to engage the lock plate at a selected position, a walk-in mechanism includes a release lever rotatable on the handle shaft and being provided with an upward projection and a lateral projection, and a resilient plate having one end secured on the movable track, an intermediate portion provided with a downward projection and a flexible end portion formed with an opening to receive the upward projection of the release lever. The release lever is loaded toward a first position in which the projections of the release lever are respectively disengaged from the resilient plate and the detent lever and is connected to the back rest of a front seat in such a manner that when the back rest is tilted forwardly, the release lever is rotated to a second position in which the projections of the release lever are respectively engaged with the opening of the resilient plate and the detent lever to disengage the detent lever from the lock plate and maintian it in a disengaged position.
