Title: ROTARY DAMPING MECHANISM WITH PIVOTAL VANES
Abstract:
A damping mechanism that includes a housing having fluid disposed therein and an inner circumferential surface, an axle shaft that is rotatable with respect to the housing, and a first vane having a distal end and being pivotally associated with the axle shaft. When the axle shaft rotates in a first direction, the first vane pivots to a deployed position, and when the axle shaft rotates in a second direction, the first vane pivots to a stowed position. A first clearance is defined between the distal end of the first vane and the inner circumferential surface of the housing when the first vane is in the deployed position, and a second clearance is defined between the distal end of the first vane and the inner circumferential surface of the housing when the first vane is in the stowed position. The second clearance is greater than the first clearance.
