Abstract:
A chair apparatus comprising:a base frame;an intermediate frame coupled to the base frame;a resident support frame including a back section, a seat section, and a leg section pivotally coupled to the base frame and the intermediate frame by a plurality of links including a first linkage having a first end pivotally mounted to the resident support frame and a second end pivotally mounted to the base frame, the plurality of links cooperating to permit the support frame to move from a chair position to a flat position;a cylinder and piston pivotally coupled between the intermediate frame and the base frame to hold the intermediate frame in a selected position relative to the base frame;a first actuator coupled to the cylinder to release the piston and permit tilting movement of the intermediate frame relative to the base frame to recline the support frame relative to the base frame;a spring assist coupled between the intermediate frame and the support frame;a locking mechanism coupled between the intermediate frame and the support frame to hold the support frame in a desired position relative to the base frame;a second actuator coupled to the locking mechanism to release the locking mechanism and permit movement of the support frame relative to the base frame; anda push handle coupled to and extending from the back section, wherein the first actuator is coupled to the push handle.
