Abstract: A seat belt retractor comprising seat belt webbing; a spool for storing webbing thereon, the spool rotationally mounted on a frame; a rewind spring for rewinding or retracting the webbing; at least one drive gear having gear teeth mounted for rotation with the spool; an auxiliary shaft rotationally mounted on the frame including a least one driven gear thereon in meshing engagement with the at least one drive gear; a ratchet nut mounted to rotate with and slide along the auxiliary shaft; a first lock bar for preventing the rotation of the ratchet nut while permitting the nut to slide relative to the auxiliary shaft; a first energy absorbing bushing mounted about the auxiliary shaft and in selective contact with the ratchet nut for generating when deformed by the ratchet nut a relatively constant reaction force on the spool to oppose any protraction of the webbing during an emergency.

Abstract: An energy absorbing seat belt retractor comprising: a frame (22); a spool (24) rotatably mounted relative to the spool including a lock wheel (212) having a plurality of lock teeth (214) associated therewith and adapted to receive a seat belt thereabout; a lock pawl (224) for engaging the spool upon sensing a one of a vehicle deceleration and seat belt extraction above certain determinable levels; and movable nut (90)located in the spool and for prohibiting relative movement between the lock wheel and spool below a threshold input force level generated in part by occupant load on the seat belt and for generating in cooperation with a deformable bushing (100) having known deformation characteristics, the characteristics of which are controlled by a movable sleeve (242) moved about the bushing, to generate a controlled energy dissipating reaction force on the seat belt.

Abstract: A load absorbing retractor comprising: a rotating spool or reel, seat belt webbing secured to the reel; at least one movable bushing, responsive to loads generated during an emergency situation, for deforming a portion of the reel and in so doing dissipating a determinable amount of the energy.

Abstract: A safety restraint system comprising: a safety belt system for restraining an occupant comprising: a safety belt; a retractor for protracting and retracting the safety belt, a shoulder belt support for supporting the shoulder belt portion of the safety belt; a pretensioner for providing, subsequent to activation, a preload tensile force in the shoulder belt portion in excess of a first low limit value of about 50 pounds; a load limiter for limiting the loads imparted by the shoulder belt portion to an occupant, operative after the preload acts on the shoulder belt portion, including first means for introducing a predetermined amount of slack in the shoulder belt when the belt tension is above a second low limit value and for preventing such slack introduction when belt tension is lower than such second low limit value.

Abstract: A safety device comprising: a retractor (22) for protracting and rewinding a safety belt to be worn about an occupant, having a lock wheel (42) and an associated lock pawl (74) movable into engagement therewith upon sensing an emergency condition by a sensing mechanism (50); a pretensioner for rotating the spool in a belt winding direction and a rotary element (80) for converting pretensioner motion to rotary motion and a spring loaded mechanism for providing for locking readiness of the lock pawl and operable after activation of and during rotation of the spool in the belt winding direction. Each of the frame sides includes a positioning hole or opening 70a and 70b through which the tie bar 72 of the present invention extends. If the retractor uses two lock wheels, two such lock pawls would be used.

Abstract: A seat belt system includes a first mounting bracket and a belt buckle, and a first connecting member connectable with the belt buckle and the first mounting bracket. The first connecting member is coupled with the first mounting bracket and is movable relative the first mounting bracket between retracted and extended positions. A first biasing device is provided for biasing the first connecting member in the retracted position. A corresponding retractor assembly coupled with a second mounting bracket and movably biased relative the second mounting bracket between like retracted and extended positions is also disclosed for use in conjunction with the seat buckle assembly to cause the seat belt to move upwardly rather than laterally relative the occupant, thereby preventing chafing of the occupant by the seat belt and reducing lateral accelerations applied to the upper torso of the occupant by the seat belt system.

Abstract: A seat belt assembly includes a tongue, a buckle, a frame mountable to a vehicle seat, linking articles for linking the tongue and buckle to the frame, a retractor assembly operable to pay out and retract linking articles connected with said tongue, the tongue thereby extendable from a retracted position to an extended position lockingly engaged with said buckle. The tongue, buckle, linking articles and retractor assembly are all mounted in operable combination to the frame, the resulting frame means combination being mountable as a unit to a vehicle seat. The seat belt assembly also includes tongue and buckle sleeve assemblies which are mountable to the frame and which cover the linking articles in the retracted position, and which support the tongue and the buckle in a desired user access position.

Abstract: A retractable tie-down assembly that enables a transportable item to be secured on a trailer. The retractable tie-down assembly is assembled about a frame that is permanently attached to the trailer. Webbing or other strap material has one end which is attached to a spool that is rotatably mounted to the frame. The spool includes a pair of side walls which are formed in the shape of ratchet wheels. A handle is movably mounted on the frame and includes a pawl that is engageable with the ratchet wheels and capable of rotating the ratchet wheels and spool in its retracting direction to take up webbing onto the spool and tighten the same. The retractable tie-down assembly also includes a lock that is capable of locking the spool against rotation in its pay out direction.
