ABSTRACT:
A wheelchair seat has a backrest assembly with a counter balance to provide equilibrium. A control loop is included on the sliding backrest to sense the onset of shear and compensate the backrest to a zero shear position during recline. A legrest assembly has a selectable lift arrangement for either independent or recline lift.
