ABSTRACT:
A fluid-damped automotive door latch actuator comprising a fluid cylinder mounted adjacent the inside surface of an escutcheon plate between the door handle crank arms. A shaft connected to and extending between the crank arms is rotated to actuate the door latch. Damping action is caused in one embodiment by rotation of a shaft-mounted vane relative to a cylinder housing fixed to the escutcheon plate. In a second embodiment, the damper is designed to provide a fluid shearing action.
