Abstract
Abstract 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.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
191 words
An armrest assembly for a vehicle, comprising: a base adapted for mounting in the vehicle; a translational member slidably mounted for vertical movement with respect to said base; a movable armrest coupled to said translational member for movement therewith; a loadable actuator having first and second ends, said first end of said actuator being operatively coupled to said armrest for moving said armrest when loaded; a first support member positioned beneath the movable armrest and having first and second ends, said first end of said first support member being pivotally coupled to said base; a second support member positioned beneath the movable armrest and having first and second ends, said first end of said second support member being pivotally coupled to said second end of said first support member, and said second end of said second support member being pivotally coupled with respect to said translational member; and said second end of said loadable actuator being pivotally coupled to said first support member intermediate said first and second ends of said first support member whereby to provide a moment arm to facilitate loading of said actuator as said armrest is lowered.
Claim 2
Dependent Claim
191 words
An armrest assembly for a vehicle, comprising: a base adapted for mounting in the vehicle; a translational member slidably mounted for vertical movement with respect to said base; a movable armrest coupled to said translational member for movement therewith; a loadable actuator having first and second ends, said first end of said actuator being operatively coupled to said armrest for moving said armrest when loaded; a first support member positioned beneath the movable armrest and having first and second ends, said first end of said first support member being pivotally coupled to said base; a second support member positioned beneath the movable armrest and having first and second ends, said first end of said second support member being pivotally coupled to said second end of said first support member, and said second end of said second support member being pivotally coupled with respect to said translational member; and said second end of said loadable actuator being pivotally coupled to said first support member intermediate said first and second ends of said first support member whereby to provide a moment arm to facilitate loading of said actuator as said armrest is lowered.
