Definitions

  • the invention relates to a belt buckle for a seat belt according to the preamble of claim 1.
  • the load-bearing frame of known buckles is made usually from a stamped sheet metal, which is about a central axis is bent until an upper and a lower part are formed, which in approximately parallel to each other, but spaced apart. Spacers are usually also on the top and bottom provided to prevent the parts from becoming too have a small distance from each other. The bent stamped part will subsequently paid. When it comes to remuneration, the framework spreads again, and the distance between the upper and lower part increases themselves at their free ends. The distance can become so large that the Frame is no longer suitable for installation in a buckle and a Represents committee part. Such committee parts must at fully automatic feeding of the individual parts for assembly on time be discarded.
  • the invention provides a buckle with a frame in which Manufacturing the risk of generating too wide a gap Frame can be almost excluded and the overall cost can be produced. This is at the beginning of a belt buckle mentioned type achieved according to the invention by the features of claim 1. In the belt buckle according to the invention concluded that the distance between the upper and lower part enlarged.
  • the side protruding, first extension serves to connect the upper part with the Base.
  • the first extension is U-shaped around one side slightly protruding, second extension bent on the other part This second extension serves in the preferred embodiment at the same time as a spacer between the upper and lower part by is angled towards the opposite part.
  • the corresponding stamped part includes this Embodiment preferably the punched blanks of several Frame that over the extensions serving as bridge members are interconnected. A continuation between neighboring ones Blanks become close to one blank and another extension close of the other blank separated so that the first and the second extension can be formed on one side edge. The distance between the neighboring blanks can be formed in such a stamped part be kept very low, what the manufacture of a frame makes it cheaper.
  • FIG 1 is a portion of a stamped part 1 with two contiguous, punched blanks for load-bearing frames 3, 3 'shown, one of which in the belt buckle shown in Figure 2 5 is installed.
  • Each blank has an elongated, plate-like shape Shape with some recessed and some deepened and sublime Areas that are not discussed in more detail below.
  • the blanks of the frame 3 are through at their upper and lower ends Bridge members 7, 9 connected to each other. For separating the blanks the bridge member 7 in the middle in the 11 marked Area separated so that on each frame 3, 3 'a first extension 13, 13 'is formed.
  • the intermediate piece 15 is punched out, so that the frames 3, 3 'each have one second, in comparison to the first extension 13, 13 'slightly, have laterally projecting extension 17, 17 '.
  • the extensions 13, 13 ' and 17, 17 ' are equally spaced from a central axis 19 so that the extensions 13, 17 and 13 ', 17' after bending the blank around the Center axis 19 are arranged one above the other.
  • By bending resulting halves of the blank form an upper part 21 and Lower part 23, which are approximately parallel to each other, but from each other spaced and connected by a centrally recessed web 25 are. Through the recess there is an insertion opening 31 for the Tongue of a fitting part between the upper and the Lower part 21 or 23 can be added.
  • the second extensions 17 for determining the distance between the Upper and lower part 21, 23 towards the lower part 23 and the first Extensions 13 angled towards the upper part 21 so that they rest on each other.
  • the protruding laterally outwards first extensions 13 are also around over the second extensions 17 bent (see FIG. 2), so that the second extensions 17th capture positively.
  • the distance between the top and bottom 21 or 23 is therefore always constant. Even a heat treatment after bending the stamped part 3, e.g. in the form of remuneration not this distance, so that the number of not exactly as one excessive distance between the upper and lower parts 21 and 23 having frame can be kept very low.
  • the frame 3 is after the bending and the corresponding bending the extensions 13, 17 and the subsequent heat treatment in one Belt buckle housing 33 mounted.
  • Recesses arranged one above the other 31 (see also FIG. 5) in the upper and lower part 21, 23 serve for Riveting the belt buckle 5 on a not shown Attachment fitting.
  • the second embodiment of a stamped part 1 'shown in FIG. 3 differs from that shown in Figure 1 in that the Bridge members 7, 9 are not halved, but that the Bridge member 7 near the frame 3 'and the bridge member 9 near the Frame 3 is separated, as by the cutting or punching tools symbolizing, hatched circles 35 is indicated.
  • the upper part 21 has the laterally protruding extension 13 and the lower part 23 the slightly laterally projecting extension 17 on.
  • the embodiment shown in Figure 6 has instead of the Recesses 31 provided in the embodiment shown in FIG. 1 each have a large, slot-like opening 31 'on the top and on Lower part 21, 23 on top of each other when the stamped part is bent are arranged. Through the openings 31 ', the belt buckle can Belt strap or attached to the vehicle via one or more ropes become.
  • FIGS. 7 to 9 correspond largely that in Figures 3 to 5 in corresponding views shown embodiment.
  • the four openings 31 for Fastening the buckle on a fitting is only two slot-like openings 31 'are provided through which also in this Buckle a webbing or rope can be pulled around it with to connect the vehicle.
