Abstract
A reclining seat includes a base, a back frame and back support connected to the back frame for translation relative to the back frame. In a first embodiment, a mechanism is provided to couple the back frame to the back support such that rotation of the back frame relative to the base automatically translates the back support relative to the back frame. In a second embodiment, a mechanism is provided to allow a user to control movement of the back support independently of back frame rotation. Preferably, the reclining seat is incorporated into a wheelchair.
