Adjustable armrest with motion control

摘要: An armrest includes an support and a subassembly supported thereon for vertical adjustment by height device having rotatable high-lead-angle threaded shaft, mating nut, trigger. The shaft member is upon force being placed on the subassembly, trigger engages to prevent rotation fix selected position. housing, cap, pair of swing arms pivoted each housing cap adjustably supporting rotational translational horizontal movement. Horizontal controlled choice materials, frictional wave spring dampener. Optionally, keyhole slot one links configured protrusion shaped selectively linearly slide along long part . or rotate in circular end slot.
