Kinematic structure for vehicle armrest

摘要

An armrest assembly is provided for a vehicle. A base is mounted to the vehicle and includes a translational member slidably mounted for vertical movement with respect to the base. An armrest is coupled to the translational member. A loadable actuator having first and second ends is coupled at its first end to the armrest. A first support member having first and second ends is pivotally connected at its first end with respect to the base. A second support member having first and second ends is pivotally connected at its first end to the second end of the first support member, and pivotally connected at its second end with respect to the translational member. The second end of the loadable actuator is pivotally coupled with respect to the first support member intermediate the first and second ends of the first support member, whereby to provide a moment arm to facilitate loading of the actuator as the armrest is lowered. A kinematic structure is also provided for use with an air spring assembly.
