Abstract:
A self-locking system in combination with a mobile chair of the type having a seat, said self-locking system comprising a lock mounted to said chair and displaceable between idle and functional positions for selectively locking the chair against movement, and a state selector operatively connected to said lock for detecting the intent of an occupant to rise from the chair and then automatically causing said lock to move to said functional position thereof, wherein said state selector is actuated by a 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, wherein once actuated, said state selector transmits a force to said lock to displace said lock to said functional position, thereby allowing the chair to lock in a stationary position before the occupant starts to lift his weight from the seat of the chair.
