A motor vehicle drive assembly, which is equipped with an electric motor and an output element, which is driven by the electric motor indirectly or directly. Furthermore, a spring associated with the output element is realized, which spring is designed to bidirectionally return the output element. According to the invention, the spring is designed as a spiral spring which is designed to be windable and unwindable proceeding both from the inner spring let and from the outer leg.

A retention assembly may comprise a motor assembly and a self-locking worm drive coupled thereto. A cam may be fixed to a worm gear of the worm drive. The retention assembly may further comprise an actuation shaft including a follower. The actuation shaft may be displaceable over a displacement range via rotation of the cam. The retention assembly may further comprise a securement member with a securement member follower, the securement member coupled to a portion of the actuator shaft. The retention assembly may further comprise a housing cam included as part of the retention assembly housing and against which the securement member follower may be biased. The securement member may be in an open state when the actuation shaft is in a first position. The securement member may swing outward to a retaining position as the actuation shaft is moved to a second position.

A power closure actuator for powering a movable closure includes a shaft situated between an electric motor and an output member. A brake device along the shaft is actuable via an electric brake actuator to apply braking. An active brake clamp is movable by the electric brake actuator. An axially floating rotor is rotatable with the shaft and has a first axial side facing the active brake clamp a second axial side providing a second braking surface. A passive backing brake clamp is positioned adjacent the second braking surface. The axially floating rotor is biased away from the passive backing brake clamp by a first biasing member. Deflection of the first biasing member coupled with axial movement of the active brake clamp and the axially floating rotor enables braking by pinching action of the axially floating rotor between the active brake clamp and the passive backing brake clamp.

A powered actuator for moving a motor vehicle closure panel from a closed position to an open position and method of construction thereof. Powered actuator includes an electric motor configured to rotate a driven shaft and a gearbox coupled to the driven shaft. An extensible member extends through the gearbox to a proximal end on one side of the gearbox for attachment to one of a vehicle body or the closure member and to a distal end on an opposite side of the gearbox. Extensible member is configured to move between retracted and extended positions in response to rotation of the driven shaft. A contamination cover enshrouds the extensible member between the gearbox and the distal end of the extensible member. Contamination cover moves between an axially extended state and an axially retracted state while the extensible member moves between the respective retracted position and the extended position.

An actuator for opening and closing a decklid or other closure on a motor vehicle is described and shown. The actuator can include a motor, a rod coupled to and driven by the motor, a first sleeve coupled to and driven by the rod, and a second sleeve coupled to and driven by the first sleeve. The first and second sleeves can be slidably coupled to one another, and/or can be rotatably locked relative to one another.

In accordance with one aspect of the present disclosure, a movable barrier operator including a body, a motor supported by the body, and a rotatable drive supported by the body and configured to be connected to an elongated driven member. The movable barrier operator further includes a shaft supported by the body and a compound gear mounted on the shaft. The compound gear includes a first gear operably coupled to a drive shaft of the motor and a second gear operably coupled to the rotatable drive. The first and second gears connected such that turning of the first gear causes turning of the second gear.

The present invention relates to a drive device, comprising a cable which is connected at one end to a cable pulley, an actuator for driving the cable pulley, and a torsion bar which generates a torsional moment, wherein the torsion bar is supported on a higher-level assembly in such a way that it can move between a first and a second state of the torsion bar, wherein the torsion bar applies a torque in a first direction over a first partial movement range, applies a torque in a second direction opposite to the first direction over a second partial movement range, and does not apply torque over a third partial movement range. The present invention also relates to a superordinate hatch arrangement.

A device for moving a leaf door, including an electric motor (30), a reduction gear box (40) and a crown wheel-pinion transmission system (50) is provided. The electric motor (30) is kinematically connected to the reduction gear box (40), which in turn is kinematically connected to the crown wheel-pinion transmission system (50). The reduction gear box (40) is reversible.

An open roof construction for a vehicle comprises a panel for opening and closing an opening in the fixed roof of the vehicle by means of at least one lever assembly connected to the panel. A stationary frame is fitted in the opening of the fixed roof. A drive motor is placed in the vicinity of the rear edge of the opening and in the vicinity of a longitudinal center line of the opening. The drive motor comprises an output shaft having a center axis which is perpendicular to a center axis of a rotor shaft of the drive motor. The drive motor is connected to a motor support which is attached to the frame by means of vibration dampers. The motor support supports a separate gearbox which is capable of transferring the driving torque from the drive motor to the at least one lever assembly connected to the panel.

An in-vehicle device includes: a movable member; a motor that moves the movable member; at least one detection switch that detects movement of the movable member; and a controller that controls the motor based on a detected output of the detection switch. The in-vehicle device further includes: a locking mechanism unit that, upon determination by the controller based on the detected output from the detection switch that the movable member reaches an end point region in a movement direction, locks the movable member, and upon determination by the controller that a main switch is set to OFF, releases the lock; and a motor driver that, after the release of the lock by the locking mechanism unit, upon determination by the controller based on the detected output from the detection switch that the movable member is moved again, drives the motor to move the movable member.
