Definitions

  • the invention relates to a belt buckle for a seat belt, in particular for fastening to a flexible fitting part in the rear seat area of motor vehicles, with a lock tongue which can be inserted into an insertion opening of the lock housing against the action of a spring-loaded ejector and can be locked by means of a lock latch part which is movably mounted in the lock housing Unlocking of the belt buckle, spring-loaded pushbutton arranged on the side of the lock housing opposite the insertion opening for the lock tongue, and in its actuating direction during the unlocking stroke of the insertion direction of the lock tongue is set to act in the opposite direction.
  • the known belt buckle has a locking part which is movable orthogonally to the insertion path of the locking tongue and which is under spring force and engages in the locking opening formed in the locking tongue when the locking tongue is inserted.
  • the locking part In the unlocked position, the locking part is held out of the insertion path for the lock tongue by an ejector traveling underneath its movement path. Due to the orthogonal direction of movement of the locking part, correspondingly high opening forces occur when the lock is opened and the overall height of the belt lock is correspondingly large.
  • the invention is therefore based on the object to reduce the overall height and the opening forces in a belt buckle with the generic features.
  • the invention provides that the locking element in its locking position by a in the lock housing between a release division for the Locking part and a locking position movable locking element is fixed and the ejector spring, which is supported between the ejector and the locking element and is tensioned by the inserted lock tongue, prestresses the locking element in its locking position, the push button acting on the locking element during the unlocking stroke and shifting it against the action of the ejector spring in its release position , Due to the swivel mounting of the locking part in the lock housing, the overall height of the buckle is reduced. At the same time, the opening forces when opening the lock are reduced because the unlocking stroke of the locking part turns out to be shorter with a pivoting movement.
  • the locking safety is improved due to the additionally provided securing element. Due to the arrangement of the ejector spring between the ejector on the one hand and the displaceably arranged securing element on the other hand, the spring tension of the ejector spring is increased by the displacement of the securing element into the release position for the locking part during the unlocking stroke of the pushbutton, so that the ejector function of the ejector also when the belt buckle is unlocked is improved.
  • a belt buckle with a plug-in movement of the lock tongue and the unlocking stroke of the push button with an additionally provided securing element for fixing the locking part in the locking position is known from DE 40 07 916 AI.
  • the securing element is designed in the form of a frame with an opening receiving the locking part, the insertion opening facing crossbar abuts the locking part in its locking position and the pushbutton-side crossbar forms the abutment for the ejector spring.
  • the securing element is preferably formed in a Z-shape in its longitudinal direction between the transverse webs with an upper Z-leg, which overlaps the locking part, and a lower Z-leg arranged in the plane of movement of the ejector.
  • the pushbutton has an actuating projection lying in the plane of the lower Z leg of the securing element.
  • the locking part is mounted in the lock housing in such a way that in the unlocked position, the locking element is pretensioned in the direction of the locking position by the locking element biased into the locking position the locking part rests on the ejector in the foremost position when the buckle is unlocked. Due to the mutual tensioning of the locking part, securing element and ejector caused by the engagement of the ejector spring, it is advantageously ensured that rattling of the belt buckle is avoided when the lock tongue is not inserted, because there are no freely moving parts.
  • the locking element engages under the locking part by means of inclined surfaces arranged on it and moves the locking part from the locking position into the unlocked position when it is shifted from the locking position into the release division.
  • FIG. 3 shows the subject of FIG. 2 with the lock tongue inserted somewhat further
  • FIG. 6 shows the subject of FIG. 5 as the unlocking stroke of the pushbutton progresses during the movement of the locking part from the locking position into the unlocked position.
  • the ejector spring 1 which prestresses the ejector 10 in its front position, is supported on the rear on a securing element 14, which is Z-shaped; there is an upper Z-leg 15, which extends above the ejector 10, and also a lower Z-leg 16, which runs in the plane of the ejector or the ejector movement.
  • the Z-shaped securing element 14 is generally frame-shaped, the Z-legs 15 and 16 each forming the legs extending in the longitudinal direction of the lock, which are connected by a front crosspiece 13 which, when the securing element is in the secured position 14 ( Figure 4) defines the locking part to be described.
  • the belt buckle is locked in such a way that a buckle 22 with a buckle opening 23 is inserted into the buckle, and here into the opening 13 of the ejector 10, so that when the buckle 22 is displaced in the direction of the arrow 30 the ejector is moved to the right in the same direction as the lock tongue 22.
  • the ejector spring 1 1 is thus tensioned, so that the prestress acting on the locking part 18 is simultaneously increased via the correspondingly loaded securing element 14.

Abstract

L'invention concerne une boucle, destinée à une ceinture de sécurité, qui présente un bouton-poussoir disposé sur le côté du corps de boucle opposé à l'ouverture d'insertion ménagée pour la languette de boucle. Cette boucle se caractérise en ce que la partie de verrouillage (18, 19) est bloquée dans sa position de verrouillage au moyen d'un élément de sécurité (14) qui peut être déplacé dans le corps de boucle entre une position de libération de la partie de verrouillage (18, 19) et une position de sécurité. Elle se caractérise également en ce que le ressort d'éjecteur (11), qui est placé entre l'éjecteur (10) et l'élément de sécurité (14) et tendu par la languette de boucle (22) insérée, maintient l'élément de sécurité (14) dans sa position de sécurité. Le bouton-poussoir (24) agit sur l'élément de sécurité (14) lors d'une poussée de déverrouillage et l'amène dans sa position de libération, à l'encontre de la pression du ressort d'éjecteur (11).
