Abstract:
A seat height adjuster drive for a vehicle seat, comprising:a drive with a manually actuatable lever mounted for movement from an idle position within two sector ranges that are different from one another, wherein the drive is responsive to movement of the lever within a first of the sector ranges to rotate a rotatable component of the drive and thereby cause movement of the drive in a first adjustment direction; a releasable freewheel for releasably blocking rotation of the rotatable component, wherein the releasable freewheel is responsive to movement of the lever through a second of the sector ranges to allow movement of the drive in a second adjustment direction; and a switch that engages a guide track, wherein the guide track is mounted for moving with the lever relative to the switch, and the switch is mounted so that the movement of the guide track relative to the switch causes the switch to move a plate cam of the freewheel in a direction opposite to the movement of the lever, so that the freewheel is released to allow rotation of the rotatable component in the direction of the movement of the lever.
