Definitions

  • the invention relates to a belt buckle for a restraint belt with a spring-loaded ejector which can be brought into engagement with a belt tongue which can be inserted into an insertion channel, and with a bolt which can be inserted in a form-fitting manner in at least one recess in the tongue.
  • Belt buckles of the type described are known from the prior art in a wide variety of embodiments and are used in particular in motor vehicles to anchor the tongue of a belt.
  • EP-A-211 718 which describes the closest prior art against which the main claim is delimited, shows a belt buckle with a bolt and an ejector.
  • the overall construction of the buckle is chosen so that it is exactly adapted to the tongue used. If the shape and / or size of the tongue is changed, a complete structural modification of the buckle is required.
  • a lock for seat belts is already known, which is constructed according to another basic technical principle.
  • a fixed pawl is provided on the bottom of the housing, on which the belt tongue is placed.
  • the belt tongue is not inserted into the housing in the longitudinal direction, rather it has to be additionally tilted after insertion. It follows from this that the housing construction of the belt buckle has to be specially adapted to the shape of the tongue, an adaptation by changing the ejector is not possible.
  • the invention has for its object to provide a buckle of the type mentioned, which is adaptable to the different sizes of tongues with a simple structure and simple, inexpensive to manufacture.
  • the insertion channel is dimensioned such that the largest tongue to be used can be inserted therein and that the ejector is provided with a head designed as an adapter to adapt to different thicknesses and widths of the tongue.
  • the belt buckle according to the invention is characterized by a number of significant advantages. Since the size and arrangement of the recess in the tongue, into which the latch can be inserted, varies only slightly and therefore does not require any further adaptation to different tongue sizes, the ejector is the component that must be adapted to reliably eject the tongue when the buckle is released and to prevent the tongue from rattling in the buckle housing when the tongue is locked.
  • the design of the ejector provided according to the invention, in particular the additional adapter used makes it possible to both safely eject the most varied sizes of tongues and to prevent their vibrations, which lead to noise. Since, according to the invention, the insertion channel is dimensioned such that the maximum largest tongue that can be used can be inserted, no additional structural changes are necessary, since smaller tongues can also be introduced into the insertion channel of the belt buckle.
  • the belt buckle according to the invention thus makes it possible to get by with a single housing construction and thus offers the possibility of simplifying the manufacture and, in particular, of designing it inexpensively and, on the other hand, of taking into account the safety requirements in that only a single, tried and tested construction has to be provided.
  • the head has a plurality of separable areas. Since the ejector is usually made of plastic material, for example in an injection molding process, it is thus possible to change the dimensions of the prefabricated head by a simple punching or cutting tool to such an extent that an adaptation to the tongue to be used is possible. In particular, it is not necessary to produce different ejectors using different injection molding tools. Rather, an ejector can be produced which is adapted, for example, to the smallest tongue to be used, ie to a tongue, the thickness and width of which Has minimal dimensions. By punching out or cutting off areas of the head of the ejector, this can be widened, shortened or adapted in some other way, for example. Such punching or cutting operations can be carried out using the simplest tools without great technical effort and thus make it possible to produce even small numbers of belt buckles for special applications while maintaining a basic construction built in very large numbers.
  • the head is provided at the front end with two lateral, projecting lugs, which can be used for adaptation to different widths of the tongues.
  • the middle, frontal area of the head can be provided with a rib which extends over its entire width and can serve to adapt to different thicknesses of tongues.
  • the rib delimits the area of the end face which lies against the end face of the tongue.
  • the rib preferably occupies only part of the height of the head and is furthermore advantageously bevelled towards the center of the end face of the head in order to facilitate insertion or engagement of the tongue.
  • the head on his front end for introducing the end of the tongue is provided with a recess.
  • This shape is particularly advantageous because the design of the recess causes the front area of the tongue to be inserted into the head of the adapter to a different extent in accordance with its dimensions and thus to be gripped or held by the adapter.
  • the recess is provided with centering flanks pointing towards the center of the front end. This prevents accidental jamming or an inclined tongue.
  • At least one support element for supporting the tongue can be arranged in the area of the insertion channel if a smaller tongue not having the maximum size is to be used.
  • the support element can be designed, for example, in the form of a deformed wall area of the insertion channel, but it is also possible to apply an additional support part to a wall of the inlet channel.
  • a metallic area of the insertion channel can be slightly deformed, i.e. be bent in particular in order to limit the free cross-sectional area of the insertion channel.
  • an additional, inexpensive support part can be provided, which is attached in the region of the inlet duct.
  • the support part it is also possible to design it in the form of an adapter or adaptable part, which can also be adapted to the shape of the tongue cross section by a simple cutting or punching process and in the non-cut or punched form, for example the insertion channel to the minimum limited tongue cross-section.
  • spring elements for example resilient tongues, which are deformed more or less depending on the respective dimension of the tongue. It is not necessary to adapt these spring elements to different tongue sizes, as this takes place automatically.
  • the belt buckle according to the invention thus allows the use of a single basic construction which can be adapted to the respective tongue sizes or shapes in a particularly simple manner. It is particularly advantageous to note that essentially only a single component, namely the head of the ejector, has to be changed for adaptation, and that this change can be carried out in such a way that the manufacture of the ejector itself is not influenced. In particular, no expensive special tools are required; rather, the adaptation can be carried out in the simplest way using automatic or semi-automatic cutting or punching tools.
  • FIG. 1 shows an exemplary embodiment of the belt buckle according to the invention in a side sectional view, only the parts of the belt buckle necessary for the invention being shown for better understanding.
  • the belt buckle conventionally comprises a metallic frame, which is punched out of a plate-shaped material and has a base plate 16, on which side flanks 17 are attached.
  • the base plate 16 and the flanks 17 are formed in one piece and are correspondingly shaped and bent in a punching and bending device.
  • bearing openings 18 are arranged laterally, in which a bolt 4 is pivotally mounted.
  • the flanks 17 further include recesses 19, in which a locking pin 20 is guided.
  • the buckle further comprises an ejector 1, against which the tongue 3 rests in the locked state, as shown in FIG. 1.
  • the ejector 1 is biased by a spring (not shown) and, when the bolt 4 is released, causes the tongue 3 to be pushed out or ejected.
  • the ejector 1 causes the tongue 3 to be held, so that undesirable noise developments are prevented. From the function of the ejector 1 it follows that this in the longitudinal direction of the buckle, i.e. can be moved from left to right or vice versa according to the illustration selected in FIG. 1.
  • the tongue 3 is inserted through an insertion channel 2 into the belt buckle, which is not shown completely in the illustration according to FIG. 1, since in particular the outer housing covers of the belt buckle are not shown and because the button was also not shown.
  • the insertion channel 2 is delimited, among other things, by the base plate 16, as shown in FIG. 1.
  • the ejector 1 comprises an adapter head 6 which can be easily adapted to the respective shapes and sizes of the tongue and which are manufactured in a basic shape can, which can be adapted to the respective requirements by simply separating, punching or cutting.
  • FIG. 3 shows a first exemplary embodiment of the head 6 according to the invention.
  • This is designed essentially in the form of a rectangular plate and has on it frontal front end, which is brought into contact with the tongue 3, side lugs 6, and a transversely extending, beveled rib 8. Since the insertion channel 2 is dimensioned according to the invention so that the largest possible tongue 3 can be inserted, that in The embodiment shown in FIG. 3 shows an adaptation of the head 6 to a narrower and thinner tongue.
  • the lateral lugs 6 are provided for width compensation, and the rib 8 compensates for the thickness.
  • FIG. 1 shows a sectional view from which this assignment is again shown.
  • the bevel of the rib 8 serves for the insertion and centering of the tongue 3 and that the front surface area of the head 6 not occupied by the rib 8 corresponds to the cross section of the end face of the tongue 3.
  • the lugs 7 can be chamfered laterally or in a similar manner in order to also facilitate lateral insertion and centering of the tongue 3.
  • FIGS. 2, 4 and 5 each show modified, ie adapted, configurations.
  • the shape of the head shown in FIG. 2 is adapted to a broad, thin tongue and was obtained by separating the side lugs 7 of the embodiment shown in FIG. 3. The separation can be carried out in such a way that the entire width of the head 6 is reduced, but it is also possible to cut off the lugs 7 by means of a lateral cut in such a way that the rib 8 is widened, based on the exemplary embodiment shown in FIG .
  • an adaptation to a thick, narrow tongue was carried out in that the rib 8 of the starting body shown in FIG. 3 was punched out.
  • 5 shows a shape in which, starting from the head shown in FIG. 3, both the lugs 7 and the rib 8 have been cut off in order to adapt the head 6 to a broad, thick tongue.
  • a recess 9 is arranged on the face of the head 6, which recess is set back and is delimited by centering flanks 10 to 15.
  • the side centering flanks 10, 11, 12 and 13 correspond in effect to the lugs 7 shown in FIG. 3 and center or hold the tongue 3 in the lateral direction.
  • the two centering flanks 14 and 15 lead to a central centering of the tongue 3. If a tongue 3 is to be used in the exemplary embodiment which is narrow and thin, this will rest in the edge formed by the centering flanks 14 and 15, while a wider one , thicker tongue is clamped in each case at the transition area between the centering flanks 10 and 11, or 12 and 13.
  • FIG. 6 can thus be adapted without additional cutting or punching processes and leads to a corresponding accommodation of the tongue.
  • the change in length of the head 6 which results from the different insertion of the tongue or from the severing processes does not play a role in the belt buckles in question, since there is sufficient in the entire mechanism Longitudinal play exists to compensate for these differences.
  • the spring preload of the ejector 1 ensures an intimate contact of the tongue and the head.
