US Patent 7878472 Auto-locking holder apparatus

A system for removably restraining an object in a vehicle includes a housing for attachment to a structure of the vehicle and at least one holder coupled to the housing for movement between an access position and a restraint position. An extensible member has a first end operably engaging the holder and a second end coupled to a retractor device. The retractor device is coupled to the housing and locks the extensible member when the vehicle experiences an event involving a rapid change in position, speed or acceleration, so that the holder is movable to the access position during absence of the event and the holder is locked in the restraint position during the event.
