Longitudinal adjuster for a vehicle seat
First Claim
1. A longitudinal adjuster that is for a vehicle seat and that is capable of being responsive to predetermined pivoting of the seat'"'"'s backrest, the longitudinal adjuster comprising:
- a first seat rail;
a second seat rail that extends in a longitudinal direction, wherein the first seat rail is mounted for moving in the longitudinal direction relative to the second seat rail;
a locking device for locking the longitudinal adjuster and thereby restricting the first seat rail from moving in the longitudinal direction relative to the second seat rail;
a memory device mounted for moving in the longitudinal direction with the first seat rail relative to the second seat rail, wherein the memory device interacts with the second seat rail for remembering a longitudinal position of the first seat rail with respect to the second seat rail so that the first seat rail can be moved in the longitudinal direction back to the remembered longitudinal position after the first seat rail has been moved in the longitudinal direction out of the remembered longitudinal position, wherein the first seat rail having been moved in the longitudinal direction out of the remembered longitudinal position is at least partially in response to the predetermined pivoting of the seat'"'"'s backrest; and
an actuation device adapted for actuating bothresetting of the memory device'"'"'s remembered longitudinal position, andthe locking device for unlocking the longitudinal adjuster, whereinthe actuation device includes an adapter and a plurality of components,the plurality of components of the actuation device are supported by and movable relative to the adapter of the actuation device,the plurality of components of the actuation device includes a pivotable member that is mounted for being pivoted relative to the adapter to actuate the actuation device, andthe actuation device, as a whole, is mounted for bothmoving in the longitudinal direction with the first seat rail relative to the second seat rail, so that each of the adapter of the actuation device, the plurality of components of the actuation device and the pivotable member of the actuation device is for moving in the longitudinal direction with the first seat rail relative to the second seat rail, andbeing movable in the longitudinal direction relative to the first seat rail, so that the adapter of the actuation device, the plurality of components of the actuation device and the pivotable member of the actuation device are all together movable in the longitudinal direction relative to the first seat rail.

Abstract
In a longitudinal adjuster (3) for a vehicle seat having a backrest that can pivot freely, a first seat rail (13), and a second seat rail (15) relative to which the first seat rail (13) can be displaced longitudinally, a locking device (16) for locking the longitudinal adjuster (3), a memory device assigned to the first seat rail (13) and interacting with the second seat rail (15), said memory device memorizing a set longitudinal seat position which is relinquished when the vehicle seat (1) is longitudinally displaced during the free pivoting of the backrest (5) and is then re-assumed once the seat is displaced back again, and an actuation device (101) assigned to the first seat rail (13), which actuation device actuates the resetting of the memory device and the unlocking of the locking device (16), the actuation device (101) is arranged with limited movement capability in the longitudinal direction relative to the first seat rail (13).
