Abstract
A self-locking system comprising a state selector for detecting the intent of an occupant to rise from a chair and then automatically causing a lock to block the mobility functions of the chair. The state detector is responsive to movement of an upper portion of the body of the occupant while the occupant is still supported in a normal seated position on the seat of the chair, thereby advantageously allowing the locking of the mobility functions of the chair to occur before the occupant starts to lift his weight from the seat of the chair.
