摘要:
An actuator for a vehicle seat has a housing, a motor with a motor shaft which has at least a first direction of rotation, a gear mechanism which is connected at the output end to the motor by the motor shaft, an actuator output drive which is connected at the output end to the gear mechanism, and a control unit. The actuator output drive has an output element which can be moved in the direction of an end position from a starting position by rotation of the motor shaft in the first direction of rotation. The direction of rotation of the motor shaft can be reversed from the first direction of rotation to an opposite second direction of rotation by the control unit, with the result that the output element can be moved in the direction of the starting position from the end position.

A latch release actuator (20) for a seat latch is configured to apply a tension onto a flexible latch release member (13) to release the seat latch. The latch release actuator (20) comprises a pulley (50) mounted to be rotatable about a rotation axis between a rest position and a latch release position. The pulley (50) comprises an attachment portion (91) for attaching the flexible latch release member (13). The latch release actuator (20) comprises a power drive mechanism (59, 61-65) to drive the pulley (50). The latch release actuator (20) comprises a lock mechanism configured to selectively lock the pulley (50) at the latch release position when the pulley (50) reaches the latch release position.
摘要:
A mechanical linear actuator having a tubular member that is defined by a housing for rotatably and axially supporting a circular nut, a lead screw is mated to the circular nut so that it can move axially in and out of the tubular member. A torsion spring clutch brake is wound about the circular nut to normally brake the nut and thus prevent the lead screw from moving into or out of the tubular member. An unlocking mechanism can remotely unwind the torsion spring clutch brake to sufficiently release the circular nut and thus allow the lead screw to pass in and out of the tubular member. An adjustable stop is provided for adjusting the stroke of the actuator.
摘要:
Continuous seat adjustment apparatus is used in conjunction with a seating device including a track assembly having an inner track and an outer track longitudinally movable on the inner track. The apparatus includes a pair of opposed jaws mounted on the outer track for pivotal movement between first and second orientations. Each of the jaws defines an opening with the inner track longitudinally extending therethrough. The jaws frictionally engage the inner track in the first orientation to substantially prevent longitudinal movement along the inner track and the jaws release the inner track in the second orientation to allow continuous longitudinal movement along the inner track. A spring device is affixed to the pair of opposed jaws to provide a bias on the jaws tending to move the jaws into the first orientation and an adjustment member is provided for moving the jaws against the spring bias from the first orientation to the second orientation.
