Abstract
A reclining backrest apparatus (10) for a wheelchair assembly (11) having a main frame (12). The backrest apparatus (10) includes a backrest frame (13) which is pivotally mounted to the main frame (12) between a normal position and a reclined position. A backrest support assembly (15) is included which slidably mounts the backrest frame (13) for movement between an extended position and a retracted position. A cord member or tendon (17) has one end (20) mounted to the backrest support assembly (15), and an opposite end (21) mounted to the wheelchair main frame (12). A pulley assembly (23) is coupled to the backrest frame (13) for pivotal movement about a horizontal axis (14) during pivotal movement of the backrest frame (13). The pulley assembly (23) engages the cord member (17) causing the support assembly (15) to move longitudinally along the backrest frame (13) between the extended position and the retracted position during movement of the backrest frame (13) between the normal position and the reclined position.
