Abstract
A furniture mechanism includes first and second side plates. First and second support members are rotatably pinned to the side plates. First and second pantograph linkage sets are each linked to one of the side plates and each extend from a stowed position to a fully extended position and support a user leg rest. A base frame includes first and second side channels. A U-shaped leaf spring interconnected to the first and second side channels and connected to the support members permits co-rotation of at least the connection plates, the pantograph linkage sets, and the support members with respect to the base frame. First and second tilt cams are rotatably fastened to the support members. The tilt cams each include multiple cam faces which define a plurality of temporary detent positions of the mechanism by contact of individual cam faces with the side channels.
