Abstract: A cable break-away device for a rescue hoist connects a cable to a cable drum of the rescue hoist. The cable break-away device provides overload protection to the rescue hoist by disconnecting the cable from the cable drum when the loads transmitted through cable become excessive. The cable break-away device is configured to fracture, releasing the cable from the cable drum, when the loads experienced by the cable break-away device exceed a predetermined failure set point. As such, the cable break-away device forms a mechanical fuse connecting the cable to the cable drum.

Abstract: A roller tube has a tubular wall and a longitudinal axis. A channel runs longitudinally in an exterior surface of the tubular wall and is configured to receive an attachment insert for sheet material such as a solar shade, movie screen, decorative shade or the like. The channel has first and second side walls that extend from an interior portion of the tubular wall toward the exterior surface. The second side wall extends further away from the longitudinal axis of the roller tube than the first side wall. This creates a lip in the exterior surface of the roller tube, enabling the attachment insert to be mounted flush with the exterior surface of the roller tube and avoiding any bumps from being formed in the sheet material as it is wound around the tube. The tube wall varies in thickness and has a relatively thick section to accommodate the channel being formed therein.

Abstract: In a webbing retractor, a stopper plate is mounted to a belt insert-through hole of a spool. In this mounted state, a restricting wall of the stopper plate extends further outward in a radial direction of a spool main body than an outer peripheral portion of the spool main body. From between a pair of leg plates of a frame, the restricting wall opposes the leg plates along an axial direction of the spool. Thus, when force displacing the spool in the axial direction of the spool is applied, the leg plates interfere with the restricting wall, and indirectly interfere with the spool so as to restrict displacement of the spool.

Abstract: A tape drive wherein a tape leader from a tape cartridge is urged through a tape path, into a take-up reel, and secured therein without the use of a buckling mechanism or a take-up leader. The take-up reel includes a locking slot defined along the central hub for receiving and locking the leader thereto. As the tape cartridge is inserted into the tape drive, an idle roller moves into position to push the leader against a motorized roller, pinching the tape leader therein between. As the motorized roller rotates, friction between the leader and rollers urges the leader through the tape path and into the take-up reel locking slot. A slight predetermined rotation of the take-up reel secures the leader with a locking member further defined within the locking slot.
