ABSTRACT:
Legrest assembly for a passenger seat is pivotally mounted to the seat frame with a spring-loaded hydraulic lock mechanism which automatically lifts a leg or foot support panel to its generally horizontal use position when a control button on the armrest is actuated. The panel is pivotally moved to its storage position under the front edge of the seat cushion when the occupant forces it down with pressure from his or her legs against the upward biasing force exerted by its spring while actuating the control button on the armrest. For maximum comfort, the legrest pad is slidable through a range of fore and aft locations in its use position and can also be locked at any angle in its range of pivotal movement. A series of interconnected links cooperate with one another and with the seat frame in such a manner so as to substantially eliminate encroachment into the normal underseat storage area. A resettable mechanism prevents damage to the assembly from excessive downward loads on the suspended legrest pad.
