Abstract: A belt shortening device for winding and unwinding a vehicle seat belt is disclosed. The device includes a spindle mounted in a frame and connected to a crank arm to facilitate winding. The spindle includes a longitudinally extending slot which communicates with a laterally extending entry opening. A seat belt, when folded, is insertable into the longitudinally extending slot via the laterally extending entry opening. Once the vehicle seat belt is positioned within the longitudinally extending slot, the crank arm is manipulated to, thereby, rotate the spindle to wind the belt therearound. The laterally extending entry opening is positioned substantially mid-way along the length of the longitudinally extending slot to prevent ejection and slippage of the belt during winding. Additional tabs are provided to hold the belt in place during winding.

Abstract: A safety belt adjusting device adapted to be secured to a three point safety belt. The safety belt adjustment device includes a pair of parallel and spaced apart rods having a threaded portion at one end, and an enlarged head opposite the threaded portion. A nut engages the threaded portion of each of the rods. Each of the rods extends through an aperture formed through a first rod retaining plate such that the plate is adjacent the enlarged heads of the rods. Similarly, the rods extend through respective apertures formed through a second rod retaining plate such that the rod retaining plate is adjacent the nuts. A sleeve extends over each rod intermediate the first and second rod retaining plate to form a belt slot having a length substantially equal to the sleeves, and a width substantially equal to the distance between the respective rods.

Abstract: A safety belt connector fitting is disclosed in association with a three-point safety belt harness wherein the connector fitting is mounted on a mid-portion of the belt to be releasably anchored to an associated push button type buckle positioned inboard of the vehicle passenger seat. The slide bar of the connector fitting has a web spanning the belt receiving aperture of the fitting base plate for entraining the safety belt through the fitting. The web has upper longitudinal corner surfaces which are truncated to provide flattened surfaces facilitating sliding movement of the belt thereby when the fitting is suspended on the belt in a stored condition. Lower longitudinally extending corners of the web have conventional right angle corner configurations to cinch the safety belt between the slide bar and the fitting base when the connector is in use to hold a passenger via lower portions of the safety belt in his vehicle seat in an emergency condition.

Abstract: Disclosed herein is a locking device for vehicle seat belt webbing. The device includes a fixed clamp member; a swing clamp displaceable relative to the clamp member between two positions, and a drum displaceable relative to the swing clamp between two positions and engageable at one of the two positions with the swing clamp so as to restrain itself from further rotation. The drum is displaced toward the swing clamp when a tensile force of a predetermined value or greater is applied to the webbing. When a further tensile force is exerted on the webbing, the swing clamp is displaced toward the fixed clamp member and holds the webbing firmly. Since the drum itself is locked, subsequent payout of the webbing can be substantially restrained owing to a frictional force developed between the drum and webbing. Thus, the webbing is actually locked at two locations. Since the area of contact between the webbing and the locking device, i.e.

Abstract: Belt adjusting device for a safety belt, including a sliding member having a slot formed therein bordered by edges of the sliding member through which a portion of the safety belt is pulled forming a loop, and a locking bar at least partly disposed within the belt loop, the locking bar being slideable transversely to the slot and having a groove formed therein extending parallel to the slot, when a load is applied to the belt the groove formed in the locking bar is aligned opposite one of the edges of sliding member bordering the slot, and the belt is pressed between the groove formed in the locking bar and the one edge of the sliding member.

Abstract: Means are disclosed for adjusting the effective position from which the shoulder or diagonal belt of a vehicle seat belt system downwardly extends. A strap is secured to extend around the seat back portion in an upright direction and slidably carries a connector to which the belt can be connected. Alternatively the upper part of the seat back portion is clamped between limbs of a U-shaped member, the front limb mounting a connector for the belt, preferably a position which can be selectively adjusted. A third embodiment comprises a strap arranged to extend upright adjacent the seat as on a door pillar, a connector for the belt being slidable along the strap. Where the system includes a running loop for guiding the belt from a retractor, one end of the strap with the connection can be connected to a second loop secured to the running loop or both loops can be mounted for swivelling independently.
