Abstract: A closure panel latch assembly can include an overslam bumper mechanism comprising a biasing element as a spring formed from a metallic material positioned relative to a slot of the latch assembly. The biasing element resists entry of a striker into the slot beyond a selected position in order to inhibit contact of the striker with a bottom end of the slot. Also provided is a closure panel latch assembly configured with the biasing element as a resilient element positioned relative to the slot of the latch assembly; The biasing element is coupled to the striker engagement member, such that the striker engagement member is positioned to engage the striker and resist travel of the striker towards the bottom end, wherein the biasing element controls the resistance to movement of the striker engagement member by the striker.

Abstract: A door latch assembly for an automotive vehicle door includes a gearless cinch actuator. The cinch actuator includes an extensible housing member connected to a threaded rod by a nut. The extensible housing member is also connected to a cable for cinching the door. A motor rotates the threaded rod, which moves the extensible housing member between rest and cinched positions. The motor is connected to the threaded rod without the use of gears. An anti-friction agent, such as a combination of a PTFE-containing coating and PTFE-containing grease, is applied between the nut and the threaded rod. The materials and anti-friction agent used at the interface of the threaded rod and nut together provide a friction coefficient (μ) of about 0.045 or less.

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.
