Patent ID: 8266982

Claim:
A dynamic system comprising: a stationary component; a first shaft coupled to said stationary component to define a longitudinal axis; a moving component engaging said first shaft and coupled to said stationary component such that said stationary component supports said moving component with said moving component movable relative to said longitudinal axis from an initial position to an actuated position; and a hysteresis assembly comprising: an elastic member support coupled to said stationary component; a first hysteresis block with a first frictional surface and a first contact surface defining a first slope; a second hysteresis block coupled to said moving component and having a second frictional surface and a second contact surface defining a second slope with said first contact surface of said first hysteresis block being adjacent said second contact surface of said second hysteresis block such that displacement of said moving component causes sliding motion of said first hysteresis block relative to said second hysteresis block along said slopes; wherein said first frictional surface and said second frictional surface selectively engage said stationary component during said movement of said moving component relative to said longitudinal axis; an elastic member engaging said elastic member support and coupled to said first hysteresis block with said elastic member disposed along a first axis transverse to said longitudinal axis; an alignment pin aligning said elastic member support and said second hysteresis block; a second shaft coupled to said stationary component and supporting said elastic member support with said second shaft being spaced from said first shaft and defining a pivot axis spaced from and substantially parallel to said longitudinal axis; and wherein said elastic member support rotates about said pivot axis during said movement and said moving component relative to said longitudinal axis.
