Abstract
A lost motion cam assembly for a vehicle lock. The assembly includes a lever, pivotally mounted to the housing and movable between locked and unlocked positions. A motor drives a gear mounted to a shaft in the housing. A cam is also rotatably mounted to the shaft, and includes a pair of opposing cam arms. When a cam arm engages a first interaction surface on the lever, the lever actuates. A second interaction surface on the lever stops the cam. The cam is operably connected to the gear by a lost motion connection that defines a range of free travel of the cam relative to the gear. Manually pivoting the lever while one of the pair of cam arms is in contact with the first interaction surface on the lever causes the cam to rotate within the range of free travel.
