Abstract

A passenger seat incorporating a path and follower mechanism for nonlinear deployment of a passenger leg rest is disclosed. The passenger seat incorporates lightweight tubular members linked to backrest linkages, the backrest linkages driven by a passenger occupying the seat, e.g., via a reclining motion of the seatback. The reclining motion drives the backrest linkages which in turn drive path followers through a curving path such that, as the path follower drives forward or backward, the leg rest deploys at a variable rate between undeployed and fully deployed configurations, consistently providing an optimally relaxing leg position at any point between.
