Abstract: A spring retractable reel having a pneumatic retraction governor or air motor for regulating the rewind speed of a spool for taking up a line of material. For example, an air motor includes a rotor having vanes, a first port opening onto one side of the rotor, and a second port opening onto a second side of the rotor.

When the drive member is activated, the operation control member is moved downward, so that the rotation allowable portion of the operation control member is located on the cylinder of the energy-absorbing-member support member. Then the brake applied to the energy-absorbing-member support member can be released to allow the rotation of the energy-absorbing-member support member.

Abstract: A seat belt retractor having first and second serially arranged torsion bars and a switching mechanism provides two levels of load limiting. A bridge bolt rotationally fixed to the inboard ends of the torsion bars is threaded into a locking base, and the switching mechanism prevents bridge bolt translation relative to the locking base in a default condition to limit seat belt load with the first torsion bar.

Additional translation of the bridge bolt relative to the locking base is prevented to re-establish load limiting with the first torsion bar. The switching mechanism includes a set of detent wedges, a retaining band and an electrically activated cutting mechanism, all disposed within the retractor frame.

Abstract: A take-up reel for winding and storing an elongate hose or electrical cable comprises a reel that is rewound by a torsional spring. A viscous clutch is coupled to the reel by means of a unidirectional clutch, which engages the viscous clutch to the reel to rewind the reward speed, but disengages the viscous clutch from the reel when the hose or cable is being payed-out. This permits the hose or cable to be payed-out without resistance from the viscous clutch. The uni-directional viscous clutch assembly thus allows the hose to be payed-out at any speed while providing the substantial safety benefits of a viscous speed governor during rewind.
