ABSTRACT:
An extensible legrest mechanism for a seating unit includes a movable legrest assembly mounted on a stationary support assembly. The legrest assembly has a pair of longitudinally movable struts which support a transverse leg-supporting member. The support assembly supports the struts in a cantilevered manner for longitudinal movement.
The legrest assembly is biased toward its extended position by a spring, a reel, and a flexible member which is wound on the reel and is connected to one of the assemblies. A brake is mounted on the support assembly and has brake shoes which are engageable with the struts and are conformable to the struts to exclude air and to provide intimate physical contact which prevents longitudinal strut movement. The brakes are operated by a pair of brake levers which are biased to positions where the shoes engage the struts, and the levers are manually operated to oppose the bias and retract the brake shoes from the struts. The leg-supporting member is pivotally connected to the struts, and a resilient member is used to bias the legsupporting member to a predetermined angular position with respect to the struts. A resiliently biased manually retractable latch is provided for engaging keepers on the movable legrest in order to hold the legrest at its extended and/or retracted position.
