Definitions

  • the force required for back tensioning can be generated mechanically by means of a strongly dimensioned spring or pyrotechnically. If the back tension force is of sufficient magnitude, especially when using pyrotechnic back tension drives, the lock can open automatically at the end of the back tension path in certain cases.
  • the automatic opening of the lock at the end of the back tightening movement is attributed to the inertia of the release button and possibly components attacking it, since the release button at the end of the back tightening movement tends to continue its movement in the back tightening direction, which corresponds to the actuation direction of the release button.
  • the separate mass body also allows the pawl to be optimally adapted to its actual purpose and to be arranged in previously unavailable places in the lock according to the known solutions, namely in the cap of the release button, in which general free space is available, so that many components of existing lock systems that are to be provided with a back tensioning device can continue to be used.
  • a reliable movement of the pawl into the locking position can be achieved with fewer restrictions than with known solutions, so that both the pawl and the mass body can be optimally adapted to the respective structural conditions.
  • the two-armed, angled lever forming the pawl is mounted on the common base of its two arms near a corner of an angled cap of the release button, so that it nestles into the cap.
  • One of the arms of the lever extends approximately in the direction of actuation of the release button and carries a latch tip which, in the locking position, lies opposite a locking edge of the housing.
  • the biasing means engages the other arm, so that the latching edge is normally not in the path of movement of the latch tip.
  • the mass body is formed by a two-armed lever 70, the first arm 70a of which is longer than the V-shaped angled second arm 70b.
  • a compression spring 72 is disposed between the arm 70a and the arm 52 of the two-armed lever 42 and holds the free end of the arm 70a in contact with the arm 46 of the bell crank 42. The operation of this embodiment is the same as that of the previously described embodiment.

Claims (3)

  1. Attache pour systèmes de ceinture de sécurité de véhicules automobiles qui sont munis d'un dispositif de rétraction (10, 20) agissant sur l'attache (12), comprenant un boîtier porteur de charge (40), dans lequel est formée une piste d'enfichage pour une languette enfichable, un verrou qui est monté sur le boîtier (40) et qui coopère avec une ouverture d'arrêt de la languette enfichable, et une touche de libération (30) guidée de manière coulissante dans le boîtier (40) parallèlement à la piste d'enfichage, caractérisée en ce que la touche de libération (30) comporte une coiffe (32) à l'intérieur de laquelle un levier coudé (42) à deux bras est monté pivotant, en ce que, à l'extrémité libre du premier bras (46) est formé un cliquet d'arrêt (48) et le levier coudé (42) peut basculer, dans la coiffe (32), entre une position normale de repos, dans laquelle le cliquet d'arrêt (48) peut, lors de l'actionnement de la touche de libération (30), passer devant un bord d'arrêt (50) du boîtier (40), et une position d'arrêt, dans laquelle le cliquet d'arrêt (48) vient en butée contre le bord d'arrêt (50) lors du déplacement de la touche de libération (30) dans la direction d'actionnement, de sorte que la touche de libération (30) ne peut pas poursuivre son déplacement, en ce que le levier coudé (42) est précontraint en position de repos par une force élastique, en ce qu'un corps d'inertie (56) est monté pivotant dans la coiffe (32) et, lors de l'accélération de l'attache dans une première direction (R) sous l'action de forces d'inertie, agit sur le levier coudé (42) afin de faire basculer celui-ci en position d'arrêt, et en ce que, lors de l'accélération de l'attache dans une seconde direction opposée, le levier coudé (42) est dissocié du corps d'inertie (56) et, de par la position de son centre de gravité (C), a tendance à adopter sa position d'arrêt ou à y demeurer.
  2. Attache selon la revendication 1, caractérisée en ce que le levier coudé (42) et le corps d'inertie (56) sont contraints élastiquement l'un contre l'autre par un ressort commun (54, 72) qui précontraint également le levier coudé (42) en position de repos.
  3. Attache selon la revendication 1 ou 2, caractérisée en ce que le corps d'inertie est formé par un levier de commande (70), et un ressort de pression (72) est disposé entre ce levier de commande et le bras (52) du levier coudé (42) opposé au cliquet d'arrêt (48).
