Abstract: The present invention provides a system to quickly and easily employ a thermal/wind barrier over the surface of a mechanical dock leveler. Dock levelers used in structures with loading docks allow air transfer and thermal conductivity into the loading dock area from the outside environment through joints and openings in and around the dock leveler, when the leveler is not in use, causing economic loss of climate controlled air. The present invention provides a system to employ a thermal/wind barrier over the surface of a dock leveler when it is not being used, so as to prevent this loss. The barrier is deployed and retracted by use of a detent clutch operated spooling mechanism. The spooling mechanism is enclosed in a housing which is mounted to the inside, bottom surface of a loading dock door. An alternative embodiment uses an electric motor to deploy and retract the barrier.

Abstract: A seatbelt retractor reduces the temporary weight during seatbelt withdrawal to increase an occupant's comfort. When a seatbelt is not being worn by an occupant (off), projections of an internal gear are placed in a circumferential center between adjacent projections by the spring force of springs. When a spool rotates in the belt withdrawing direction, the internal gear also rotates in the belt withdrawing direction. This arrangement disables a reduction mechanism's power transmission to cut off the direct connection between the spool and electric motor connected to a sun gear to reduce the temporary weight during withdrawal of the seatbelt. When the internal gear rotates at a predetermined angle, the projections come into contact with the projections to thereby stop the rotation of the internal gear. This enables the power transmission of the reduction mechanism, whereby the spool and electric motor are brought into direct connection via the reduction mechanism.
