Patent ID: 8646817

Claim:
An actuating device for a vehicle lock, comprising: a lever, pivotally movable between two positions, the lever having an interaction surface; a motor; a gear, selectively rotatable about a gear axis by the motor; a cam that is rotatable about a cam axis by the gear through a lost motion connection and having a pair of cam arms, wherein rotation of the cam from a first position to a second position drives one of the cam arms to pivot the lever, and wherein when the cam is in the second position the other of the two cam arms engages the interaction surface to stop the rotation of the cam; and a resilient bumper, wherein the lost motion connection includes a sidewall on the cam, positioned so that rotating the cam causes the sidewall to engage the gear through the resilient bumper, wherein the resilient bumper urges the gear away from the cam sidewall after stoppage of the motor from driving the gear when the cam is in the second position.
