Definitions

  • the invention relates to a fastener for seat belts, with a load-bearing frame on which an insertion path for a tongue is formed, a locking cam which is displaceably guided transversely to the insertion path and a release button which is displaceably guided on the frame and engages when actuated on the locking cam and transversely to it Insertion path oriented guide shifts.
  • a closure of this type is known from DE 42 15 563 A1.
  • the release button is actuated in the same direction, by depressing it, and due to its inertia, it strives to carry out an opening stroke if the closure is braked abruptly at the end of the penalty stroke.
  • these measures in that a pawl is pivotally mounted within the cap of the release button, which is pivoted in response to acceleration and abuts against an edge on the frame of the closure, so that the further movement of the release button in the opening direction is prevented.
  • the invention provides a fastener for seat belts, which is secured against unintentional opening even at extremely high acceleration values and does not require any fundamental changes to the proven design based on the latching cam principle.
  • the closure is provided with a bolt which is displaceably guided parallel to the direction of actuation of the release button and loaded by a spring into a rest position and responsive to acceleration in the direction of actuation of the release button due to its inertia in a blocking position in which it is in the Guide of the locking cam protrudes and blocks it in its closed position.
  • the preferably pin-shaped bolt is moved into the blocking position by its inertia and engages over the upper edge of the latching cam which is locked in an opening of the tongue.
  • the release button presses the latching cam due to its inertia as in the case of an opening stroke in the direction of its opening position, but the latching cam immediately hits the latch protruding into its guide, which now loads transversely to its longitudinal direction and consequently is jammed in its blocking position.
  • Locking cams and locking bolts lock each other at the same time as long as the release button presses against the locking cam. Then the bolt is returned to its rest position by the spring, so that the closure can be opened without hindrance.
  • the closure is characterized by a high level of security against unintentional opening, even at extremely high accelerations, as can be achieved with particularly powerful, in particular pyrotechnic, penalty drives.
  • the entire duration of the acceleration phase is available for activating the bolt.
  • the bolt is immediately clamped in its locked position. The clamping forces outweigh all other shock loads occurring in a wide variety of directions in a complex accident sequence, so that the closure remains secured in its closed position even under the toughest conditions.
  • the guide which is preferably in the form of a pin, can be integrated easily and with little effort into existing, proven locking cam designs.
  • the buckle for seat belts connects a conventional tongue 10 with a fitting 12, on which a belt pretensioner (not shown), a so-called buckle pretensioner, can engage.
  • the closure comprises a load-bearing frame 14 connected to the fitting 12, which is bent from a steel plate in a U-shaped cross section.
  • An insertion path for the tongue 10 is formed between the two parallel, plate-shaped legs of the frame 14.
  • a locking cam 16 which is loaded by a leaf spring 18 in its closed position.
  • a spring-loaded ejector 20 presses against the front end of the tongue 10.
  • the locking cam 16 is guided in a plastic part 22 placed on the frame 14, in which a guide channel 24 for the locking cam 16 is formed.
  • a release button 26 is guided on the frame 14 in the insertion direction of the tongue 10. Ramps 28 are formed on the release button 26 which, when actuated, engage under two lateral wings 16a of the latching cam and push it up.
  • the closure is provided with a pin-shaped bolt 32 which is in a bore in a guide housing 34 parallel to the actuation direction of the release button 26 is guided.
  • the guide housing 34 is placed on one leg of the frame 14, but can also be molded onto the plastic part 22.
  • the pin-shaped latch 32 has a collar at its end facing away from the latching cam 16 and is surrounded by a helical spring 36 which is supported on this collar and on an opposite support surface of the guide housing and urges the latch 32 away from the latching cam 16 in a rest position. In this state, shown in FIG. 1, the detent cam 16 is freely movable in its guide channel 24 when the release button 26 is actuated.
  • the release button 26 endeavors to remain in its movement. This movement corresponds to the normal opening stroke of the release button 26. This therefore engages with its ramps 28 under the side wings 16a of the locking cam 16 and presses it upwards against the extended latch 32.
  • the latch 32 is now loaded transversely to its longitudinal direction and in the bore of the guide housing 34 jammed. In this state shown in FIG. 2, the locking cams 16 and the latch 32 lock each other, as a result of which the locking cams 16 are ultimately secured in their closed position.
