Description

ABSTRACT:
A cross-crawl chair including a chair frame for supporting a headrest, chair back, chair seat, right and left arm supports, right and left leg supports, and four actuators for moving the supports. The chair also includes a control system which synchronizes the movement of the right arm actuator with the left leg actuator and the movement of the left arm actuator with the right leg actuator so as to provide an “arm and opposing leg” or cross-crawl motion. Further, the electro-mechanical control system controls a speed, a length of time, and a range of the cross-crawl motion.
