See full text

A locking system of a wheelchair is disclosed. The locking system includes a locking member, an actuator, a locking frame, and an opening. The opening is disposed within the locking frame. The actuator is in communication with the locking member and is configured to move the locking member within the opening. The actuator is operable in a retracted operation state and an extended operation state. The actuator is configured to move the locking member in an upward direction when the locking system is set from the extended operation state to the retracted operation state. The actuator is configured to move the locking member in a downward direction when the locking system is set from the retracted operation state to the extended operation state, and the locking member is naturally biased in the extended operation state.
