Definitions

  • the invention relates to a belt buckle for seat belt systems according to the preamble of claim 1.
  • US-A-4457052 describes a relatively large belt buckle for child safety systems in motor vehicles, which differs from that of the type mentioned in the introduction in that it has no ejector which removes the belt end pieces from the lock housing after actuation of the release button.
  • the entire locking mechanism consists of chrome-plated, steel individual parts. Furthermore, the release button is provided in the area of the top of the lock housing.
  • the metal parts of the locking mechanism involve relatively high manufacturing costs and lead to a correspondingly increased total weight of the buckle, which is a secure toddler becomes a disturbing burden, especially when driving for a long time.
  • the release button is located in the area of the top of the lock housing, the thumb pressure on the button for opening the lock also affects the stomach of the toddler, which is understandably uncomfortable for the child; unless the lock is opened manually so that the index finger is positioned as an abutment behind the lock housing and the key is then pressed with the thumb, which is, however, inconvenient.
  • the strap end pieces for the shoulder straps can be exchanged when inserted into the lock.
  • FR-A-1564227 describes a further belt buckle for belt safety systems in motor vehicles, in which two belt end pieces are provided for shoulder belts. Although these end pieces are one above the other in the inserted state, they are at a distance from one another and, since they are individually locked with the lock mechanism, can be accidentally inserted into their predetermined plug-in position in a rotated position, which results in twisted shoulder straps.
  • This buckle mainly consists of metal parts and is therefore complex and expensive to manufacture.
  • the metal lock can also heat up in strong sunlight in a motor vehicle, so that touching the lock by the child can be painful.
  • the release button is also on this lock on the top, so that when you press it on the child's stomach.
  • the object of the invention is to improve a belt buckle of the type mentioned above in such a way that the belt buckle can be produced more cheaply, is lighter and more user-friendly while maintaining its compact design and mechanical strength designed and only pluggable and lockable as intended.
  • the belt buckle according to the invention is considerably lighter in weight and at significantly lower cost while maintaining its compactness and mechanical strength, since with the exception of the ejector spring, all other components are made of plastic. Opening the belt buckle is also quicker and more child-friendly, since the opening pressure is now parallel to the length of the buckle. It is also advantageous that the belt end pieces can not be inserted into the lock housing individually but only in a predetermined position relative to one another. Furthermore, they do not have a negative impact on the compactness of the belt buckle, since the latching arms of these end pieces are designed to be insertable into the buckle housing for latching.
  • the buckle shown which is mainly used for seat belt systems for toddlers in motor vehicles, consists of a buckle housing 1 made of plastic, which in the usual way has an eyelet 2 for fastening a first end of the webbing, a locking mechanism, generally designated 3, and two further webbing end pieces 4 and 5 for further webbing ends, which are attached to it in a known manner. Since these locks are mainly used for belt systems for small children, these locks are small in size.
  • the locking mechanism 3 constructed according to the latching principle consists of an upper counter-latching tongue 6, a lower counter-latching tongue 7, an ejector 8 and an ejector spring 9 which is supported on the one hand in a blind hole 10 of the ejector and on the other hand on a wall part 11 of the mechanism 3.
  • the frame of the mechanism 3 has a crossbar 12, to which the said first end of the webbing is fastened in a manner known per se.
  • the two webbing end pieces 4, 5 consist of two locking arms 13 and 14 which, according to FIG. 1, engage one another in the closing mechanism 3 and have known eyelet parts 15 at their outer end, with which the aforementioned further webbing ends are fastened in a manner known per se .
  • the latching arms 13 and 14 are designed as flat latching tongues which are joined one above the other and are designed in a predetermined manner in such a way as to ensure that they can only be inserted into the mechanism 3 in the correct position relative to one another, and it is of course also ensured that also the insertion can only take place in a certain position.
  • the latching tongues 13 and 14 have at their inner end a latching nose 16 and 17 (FIG. 1) which projects outwards transversely to their longitudinal extension and which is attached to a stop shoulder 18 and 19 of the counter detent tongues 6 and 7 come to rest.
  • a projection 20 is provided, with both projections 20 lying directly opposite one another, which ensures that the locking tongues 13, 14 and thus the belt end pieces 4, 5 can only be inserted into the mechanism 3 in a certain position .
  • the counter-latching tongues 6 and 7 of the mechanism 3 allow the projections 20 to pass freely when the belt end pieces 4, 5 are engaged and disengaged.
  • the ejector 8 bears against the detents 16, 17 in order to be able to eject the belt end pieces 4, 5, as will be explained.
  • the counter-latching tongues 6 and 7 of the closing mechanism 3 are designed to be resilient, by using appropriate plastic material for this purpose, and have inclined sliding surfaces 21 and 22, so that these tongues can be spread apart when the latching lugs 16 and 17 of the webbing end pieces 4.5 pass along them .
  • the locking lugs are preferably also provided with inclined sliding surfaces 23 and 24.
  • the ejector 8 is arranged laterally within the mechanism 3, as shown in FIG. 2.
  • the ejector 8 is essentially opposite the release button 29.
  • Figure 2 also shows that the release button 29 is provided on one side narrow side of the lock housing 1, while a recessed grip 30 is provided on the opposite, other narrow side of the lock housing.
  • the index finger can now be gripped in the recessed grip 30 while the thumb of the same hand presses the release button 29. This will open the lock.
  • the locking of the belt end pieces 4, 5 takes place in that these end pieces are inserted into the mechanism 3 with their tongues 13 and 14, as intended according to FIGS. 3 and 4, the counter-latching tongues 6 and 7 initially moving apart and then when the End position of the detents 16 and 17 is reached, spring back again, so that the detents cooperate with the stop shoulders 18 and 19.
  • the button can be provided with a preferably injection-molded spring 31.
  • the spring is supported in the interior of the lock, for example on the lock housing 1 or on the lock mechanism 3.
  • the locking mechanism 3 is of compact construction and that the housing 1 also has a rigid shape in that the large top and bottom sides of the lock housing 1 have no opening, so that thereby there is an overall mechanically strong lock construction.
