Abstract: An electromechanical strut and method of moving a closure member of a vehicle between an open position and a closed position is provided. The electromechanical strut includes a power drive unit including a motor, a leadscrew, a planetary gearset operably connecting the motor to the leadscrew, and an electromechanical brake assembly. The electromechanical strut further includes a telescoping unit including an extensible tube and a drive nut for converting rotary motion of the leadscrew into linear motion of the telescoping unit. The electromechanical brake assembly is selectively moveable between an engaged state, wherein the leadscrew is prevented from rotating to prevent relative axial movement between the power drive unit and the telescoping unit, and a disengaged state, wherein the leadscrew is permitted to rotate to allow relative axial movement between the power drive unit and the telescoping unit.

Abstract: A power swing door actuator configured for use in a power door actuation system in a motor vehicle having a vehicle door pivotably connected to a vehicle body for movement along a swing path between open and closed positions is provided. The power swing door actuator includes a power-operated drive mechanism connected to the vehicle door with a rotary driven member configured for rotation in response to selective actuation of the power-operated drive mechanism. An elongate rack pivotably connected to the vehicle body and the rotary driven member is maintained in engagement with the rack via a retention member. Rotational movement of the rotary driven member in a first direction causes the vehicle door to move in an opening direction, while rotational movement of the rotary driven member in a second direction causes the vehicle door to move in a closing direction.

Abstract: An electromechanical strut is provided for moving a pivotal closure member between open and closed positions relative to a motor vehicle body. The electromechanical strut includes a drive mechanism having a motor-gearbox assembly, flex coupling assembly, and a spring-loaded supplemental friction assembly that are operable to drive a rotatable power screw. The drive mechanism converts rotary motion of the power screw into linear motion of an extensible member to move the extensible member between a retracted position corresponding to the closure member closed position and an extended position corresponding to the closure member open position. The motor-gearbox assembly includes a motor and a geartrain having an output component driven at a reduced speed relative to the motor speed. The flex coupling assembly is operably disposed between the output component and the power screw. The spring-loaded supplemental friction assembly generates and applies a supplemental frictional force to the flex coupling assembly.

Abstract: A door latch assembly equipped with a single ratchet-double pawl latching arrangement having a ratchet, a primary pawl and a secondary pawl. The primary pawl is configured to include a first or primary lug and a second or secondary lug, with each lug having a distinct profile to respectively provide an eccentric backout characteristic and a concentric backout characteristic in relation to the ratchet.

Abstract: A low release effort eccentric double pawl vehicle latch includes a ratchet, primary pawl, auxiliary ratchet and secondary pawl in combination with a secure lock lever.

Upon reset, the drive mechanism drives the auxiliary ratchet back to its closed state and in the process the auxiliary ratchet can engage and return the secondary pawl back to a closed state in the event of an insufficient bias force thereon.
