Abstract
Inner door lock actuator for automobiles comprises a lever-like handle which is pivotally supported in a housing about an approximately vertical shaft. The housing is attached to the door. A linkage or an actuation cord connects the handle to the door lock. A spring is arranged on the shaft for biasing the handle toward a non-actuated position. A portion of the handle is provided with a gear segment. A rotary damper is located in the housing and has a rotor shaft, a pinion being attached to the rotor shaft and meshing with the gear segment.
Claims20
An inner door lock actuator, comprising:
- a housing;
- a rotational shaft fixed to the housing;
- a handle formed as a lever pivotably mounted on the rotational shaft and having a gear segment;
- a spring element attached to the housing and the handle for biasing the handle toward a non-actuated position;
- and
- a rotary damper having a pinion meshing with the gear segment, whereby after the handle has been actuated, by an actuation movement against a biasing force of the spring element, to move from the non-actuated position, a return movement of the handle to the non-actuated position is damped by the rotary damper;
- wherein the rotary damper is arranged on the rotational shaft.
