Abstract: An automatic, rapid lock, belt roll-up clamp for vehicle safety belts is provided with a belt clamp disposed behind a winding drum. The belt is adapted to be guided with minimal friction between first and second guide points located next to a clamp lever having a joint, and between two clamping surfaces, one of which is attached to a housing, the other of which is located on the clamp lever and both of which are substantially parallel to one another when in contact. The second guide point is pivotally mounted on the housing and located separately from the clamp lever and in front of the clamping surfaces with respect to the direction of belt pull. Clamping occurs by essentially pure normal force produced by pulling action at the first guide point, located on the clamp lever. At substantially completely filled condition of the winding drum, the moving way of the belt between guide points is the same as the moving way between the second guide point and the winding drum.

Abstract: The invention relates to a device for clamping a safety belt to prevent it being unwound from a belt reel, the device consisting of a housing in which is provided a lever, one end of the lever being pivotably mounted in the housing, a clamping surface being provided on the lever intermediate its ends which co-operates with a clamping surface provided on the housing, the lever being resiliently urged to move about its pivot in a direction to separate the clamping surfaces. The belt is guided around the pivoted end of the lever, extends between the clamping surfaces and is guided around the free end of the lever, the resilient means applying a tension force to the belt. Movement of the lever against the force of the resilient means moving the clamping surface on the lever towards the clamping surface on the housing to clamp the belt therebetween.

Abstract: In accordance with this invention, there is provided a safety belt retractor comprising a frame, a spool mounted for rotation on the frame and having seat belt webbing wound thereon, first means biasing the spool in a rewind direction and means for reducing the tension of the webbing against the wearer due to the bias force of the first biasing means, the tension reducing means comprising a second means biasing the spool in a rewind direction and having a lower biasing force than the first biasing means, the tension reducing means being activated upon a retraction movement of a withdrawn seat belt followed by a slight further extension of the belt and a subsequent slight additional retraction of the belt from the further extended position, the tension reducing means operable when activated to block out the rewind bias of the first biasing means and permitting the second biasing means to apply its lesser rewind force to the spool.

Abstract: A fastening for holding the loop of a safety belt in motor vehicles comprises a clasp formed with an arm of which the underside defines a slot extending lengthwise of the vehicle for the insertion thereinto of the loop, the open end of said slot being closed by a catch which is openable by a push button mounted on the clasp base.

Abstract: A seat belt retractor of the inertia type comprises a rotatable shaft with a cam-surface driven thereby. A locking element movable on the cam surface is positively displaced by a control element fitted in a recess thereof and acting from an inertia element. The locking element, when driven by the inertia member, engages with the teeth on an annular locking ring to stop retraction of the seat belt attached to the shaft. The inertia element may be spring preloaded and a locking wheel may be provided to provide alternative locking torque for the inertia element when the car assumes a roll-over condition in which the seat belt would not ordinarily retract quickly.

Abstract: Apparatus for moving railroad cars, barges or the like along tracks includes three double-acting hydraulic cylinder mechanisms operatively supported from trackside overhead framework structure. A first, push-pull hydraulic mechanism is extensible and retractable within a plane parallel to the railroad tracks and the same is disposed toward one side of the tracks. A second, clamping hydraulic mechanism is supported upon the free end of the push-pull mechanism. As a result of the disposition of the first mechanism toward one side of the tracks, the clamping mechanism is able to positively clamp the upper side wall portion and said rail portion of the railroad car. Movement of the car in either a forward or backward mode is attained under the influence of the first mechanism. Alternatively, the push-pull mechanism can retard movement of the car and safely retains the car in a predetermined position when the mechanism is not actuated.

Abstract: A safety belt retracting mechanism having constant pull includes a rotatable spool for storing the belt inside a housing. A conventional, positive coefficient of force spring inside the housing applies a retracting force to the spool and belt as the belt is pulled by the occupant. The spring is coupled between the housing and spool through a variable gear ratio gear train having a negative coefficient of force transfer characteristic. The negative transfer characteristic of the gear train compensates for the positive characteristic of the spring to provide constant pull to the belt between fully retracted and fully protracted belt positions. Three embodiments of the invention are disclosed. In one embodiment, the changing gear ratio is produced by a pair of oppositely oriented cone gears connected respectively to the spring and to a spindle supporting the belt spool.

The characterizing constitutents of the composite sheet are: (1) a first layer of thermoplastic resin containing short glass fibers and a mineral filler such as kaolin, (2) a backing reinforcing layer comprising a long glass mat encased in a resin matrix and (3) optionally a third layer similar to said first layer.

Abstract: A safety belt retracting mechanism having constant pull includes a spindle supporting a rotatable spool for storing the belt within a housing. A conventional, positive coefficient of force spring inside the housing applies a retracting force to the spool and belt as the belt is pulled by the occupant. The spring is coupled between the housing and spool to a gear train having a negative coefficient of force transfer characteristic. The negative transfer characteristic of the gear train is caused by a changing gear ratio which compensates for the positive force characteristic of the spring to provide constant pull to the belt. The changing gear ratio is produced by a spiral-shaped gear coupled to a constant radius pinion formed on one end of the spindle. The spiral-shaped gear is formed on the hub of a containment member enclosing the spring. The containment member is mounted to the housing on a pivot arm.
