Abstract: A latch assembly for driving a closure panel from a closed panel position to an open panel position. The latch assembly comprises: a latch mechanism having a first latch element for retaining a mating latch component in a latched position and for moving the mating latch component from the latched position to an unlatched position when released, the movement of the first latch element biased towards the unlatched position by a latch biasing element; and an actuation system having: a mechanical energy storage system having a device for storing mechanical potential energy for assisting the latch biasing element in moving the mating latch component from the latched position to the unlatched position; a mechanical advantage system having a plurality of advantage elements for engaging the device, such that movement of the plurality of advantage elements is associated with a trigger force and cooperation of the plurality of advantage elements provides for amplification of the trigger force as an initiating force to release the stored mechanical potential energy; and a trigger system configured to provide the trigger force to release the stored mechanical potential energy.

Abstract: A power actuation system for a motor vehicle closure panel includes a motor operable to pivot a driven gear. At least one pawl assembly is operably supported by the driven gear for movement between a lever driving position, whereat the pawl assembly is positioned to pivot a lever coupled to the door to pivot the door concurrently with movement of the driven gear, and a lever releasing position, whereat the pawl assembly is positioned to permit free pivotal movement of the lever and door relative to the driven gear. The pawl assembly includes a roller engaged with the lever for rolling movement therealong during movement of the pawl assembly between the lever driving position and the lever releasing position, which results in minimal static and kinetic friction, thereby lending to reliable, low effort movement of the pawl assembly between the lever driving position and the lever releasing position.

Abstract: A window regulator module for a motor vehicle includes a pair of window regulator rails operably coupled to one another via at least one cable wrapped about pulleys on the window regulator rails. Each window regulator rail has a body extending lengthwise between opposite ends. The body has a main body portion and a guide edge along which a lifter travels upwardly and downwardly. The main body portion is plastic and the guide edge is metal. The metal guide edge provides the window regulator module with increased stiffness and increased cross-vehicle stability to a window carried by the lifters.

Abstract: A latch assembly is provided with a child lock mechanism having a spring system including a first spring member and a separate second spring member that requires a first force to move the child lock mechanism from an off position to an on position and a second force to move the child lock mechanism from the on position to the off position, wherein the required second force is greater than the required first force, thereby indicating to a user by tactile feedback the relative position (on/off) the child lock mechanism is in, thereby assuring intended movement of the child lock mechanism from one of the on/off positions to the other.

Abstract: A powered actuator unit for use in a closure system of a motor vehicle. The powered actuator unit includes a common housing configured to house a brushless DC (BLDC) electronic motor unit, a gear drive unit, a shift support arrangement, and a controller arrangement. The motor unit has a stator unit that includes a plurality of electromagnetic subassemblies each having a carrier and a winding unit. The carrier includes an outer ring segment being planar and an inner ring segment being arcuate and a web segment interconnecting the outer ring segment and the inner ring segment and the plurality of electromagnetic subassemblies are each adapted to abut one another in an annular arrangement upon assembly. The outer ring segments define an outer peripheral surface of the stator unit having a polygonal cross-section and the inner ring segments define a rotor cavity having a circular cross-section.

Abstract: A closure latch assembly for a motor vehicle closure panel is equipped with a common kinematic chain of components for a latch release mechanism utilizing a first range of handle travel to initiate a power release of a latch mechanism and further utilizing a second range of handle travel to initiate a mechanical release of the latch mechanism. An actuation rod may include a magnet that, when moved out of range of a sensor, signals to initiate the power release. In the event that the power release does not occur, further movement of the actuation rod forces the mechanical release. In both the power release and mechanical release, a pawl is rotated from a ratchet holding position to a ratchet release position. The actuation rod may have a first segment connected to a door handle and a second segment connected to a key cylinder, where either segment may provide the mechanical release.

Abstract: A window regulator system for a window coupled to a door and movable between fully open and closed positions and a short drop position and method of operation are disclosed. The system includes rails with window regulator lifter plate assemblies being moveable along the rails by cables. A motor winds the cables to move the window. An electronic control unit detects operation of at least one of a door handle and a latch of the door to identify a short drop request corresponding to the door shut or opened. The electronic control unit ensures that no freeplay exists in the window regulator system to provide accurate movement of the window and controls the motor to selectively raise the window to the fully closed position in response to the door being shut and temporarily lower the window to the short drop position in response to identifying the short drop request.
