Definitions

  • the invention relates to a method for producing a webbing and a method for producing a seat belt, as well as a gun band and a seat belt, which were produced in particular by the method according to the invention.
  • a seat belt webbing which is designed as a hose and has a sewn-in tear fold, which is designed in this way. that it tears open in the event of a collision due to tensile forces exerted by the belt and the opening of a valve coupled thereto causes the hose belt to inflate.
  • the belt lying before the accident as a flat tube the width of which corresponds to half the circumference of the inflated belt, is suddenly inflated.
  • it represents a certain impact cushion that is advantageous compared to the simple belt.
  • adequate protection of the vehicle passenger is not satisfactorily guaranteed due to the insignificant dimensions of the inflated hose belt.
  • An inflatable tubular restraint system is known from the international application PCT US 95/10695.
  • the seat belt system shown here consists of a lap belt and a shoulder belt, with the lap belt partially consisting of an inflatable balloon that shortens its length during inflation and thus has a belt tensioning function in addition to an impact function.
  • the passenger's abdominal cavity is particularly protected, but the shoulder and head area, apart from additional restraint of the shoulder due to the tightened belt, are not considered further.
  • This system is assembled from existing known components such as a conventional seat belt and an airbag with an inflator attached thereto in such a way that a braided hose filled with an inflatable bladder is sewn in between the end of the shoulder belt and the end of the assembly of the belt. All tensile forces in the longitudinal direction of the belt are transmitted via these seams, i.e. the longitudinal belt strength depends on the quality of these seams. So you have to be extremely accurate and complex.
  • the object is achieved with a method for producing a belt webbing on a belt weaving machine, characterized in that the belt webbing is in each case woven in one layer over a (pre) spanned first belt length and then over a (pre) determined second belt length at least over one Part of the band width is woven in two layers, in which an upper and a lower fabric layer results from the fact that the belt webbing is then woven in a single layer over a (pre) determined first band length, the second band (again) a at least over a part of the band width two-ply woven tape length follows and so on.
  • the object is achieved with a webbing according to claim 15.
  • the object is achieved with a seat belt according to claim 16.
  • Fig. 1 shows an example in a schematic perspective view of a simplified portion of a process of the invention ago l Ounen webbing.
  • Fig. 2 shows the webbing of Fig. 1 in section along the line A-A.
  • Fig. 3 shows the webbing of Fig. 1 in section along the line B-B.
  • FIG. 4 schematically shows an enlargement of a section "X" from FIG. 3.
  • FIG. 5 shows in a schematic perspective, in a highly simplified manner, an advantageous further development of a belt strap.
  • Fig. 6 shows the webbing of Fig. 5 in section along the line C-C.
  • Fig. 6a shows the webbing of Fig. 5 with round edges in section along the line C-C.
  • Fig. 7 shows the webbing of Fig. 5 in section along the line D-D.
  • Fig. 7a shows the webbing of Fig. 5 with round edges in section along the line D-D.
  • FIG. 8 shows, in a schematic perspective, an advantageous further development of a webbing in a greatly simplified manner.
  • Fig. 9 shows the webbing of Fig. 8 in section along the line E-E.
  • Fig. 10 shows the webbing of Fig. 8 in section along the line F-F.
  • Fig. 11 shows the webbing of Fig. 8 in section along the line G-G.
  • FIG. 12 shows an example of a section of a sectional illustration of a seat belt provided with an inlet.
  • 1 shows, for example, a webbing 2 produced on a double-needle band weaving machine with a first single-layer band length 4 and an adjoining second two-layer band length 6, which has a lower fabric layer 8 and an upper fabric layer 10.
  • the lower fabric layer 8 and the upper fabric layer 10 result approximately in a flat-printed hose.
  • a line SBL in the upper fabric layer 10, indicated by dash-dotted lines, indicates a portion h in the area of the belt center, within which weft thread S z B can be weakened by the action of laser beams, in order to create a so-called predetermined breaking line SBL along the fabric layer 10 SBL can never be woven into the middle of the belt as well.
  • This predetermined breaking line SBL is used in a seat belt 12 according to the invention to be produced from this belt band 2 (FIG. 12), to allow the escape of an inlet 16 arranged between the belt layers 8 and 10, which due to an ignition a trigger device (not shown) is acted upon by gas and expands explosively
  • Figure 2 shows the webbing 2 in cross-section, cut in the single-layer area along the line A-A of Figure 1, ie in the first web length 4. This web area will find space in the (not shown) retraction mechanism of a (not shown) seat belt module
  • Fig. 3 shows the webbing 2 in cross section, cut in the two-ply area along the line BB of Fig. 1, ie the second band length 6.
  • This band area will accommodate an inlet 16 between the fabric layers 8 and 10 of the seat belt 12 (Fig. 12), the function of which already has been described above
  • the webbing 2 according to the invention is woven in a fitted form in such a way that a (pre) certain first band length 4 is woven embossed and then, after a technical adjustment via a (pre) determined second band length 6, it is woven in two layers, in which the upper 10th and the lower fabric layer 8 results in that a weft repeat is completed. After a further adjustment, a (pre) determined first tape length 4 is then woven embossed and so on
  • FIG. 4 schematically shows, by way of example, the detail "X" from FIG. 3, greatly enlarged.
  • the lower fabric layer 8 and the upper fabric layer 10 can be seen, which converge at point 15 to form a single-layer fabric region.
  • the weft threads S run from right to left and vice versa Drawing plane at a right angle
  • the position shows that in the two-layer area half of the warp threads K m of the lower one Fabric layer 8 and lie in the upper fabric layer 10.
  • the webbing ends in an edge, in Fig. 4 to the right of section "X".
  • Fig. 4 to the left the two-sided fabric extends.
  • the analog connection point 15 is to be imagined (in FIG. 4) to the left of a vertical line of symmetry lying in the plane of the drawing.
  • FIG. 5 shows a webbing 202 produced, for example, on a double-needle band weaving machine with a first single-layer band length 204 and a second two-layer band length 206 adjoining it, which has a lower fabric layer 208 and an upper fabric layer 210.
  • the lower fabric layer 208 and the upper fabric layer 210 result approximately in a flattened, laterally open tube.
  • the lower fabric layer 208 and the upper fabric layer 210 can be sewn together by means of a tear seam 209 along the dashed line after an inlet 16 has been inserted into the two-layer area (tape length 206).
  • the seam 209 serves to create a so-called breaking line SBL.
  • a predetermined breaking line SBL can also be woven into the middle of the belt.
  • This predetermined breaking line SBL is used in a seat belt 12 according to the invention (FIG. 12) to be produced from this webbing 202 in order to allow the escape of an inlet 16 arranged between the fabric layers 208 and 210, which acts on gas due to the ignition of a trigger device (not shown) and expands explosively.
  • the webbing 202 according to the invention is woven in a fitted form such that a (pre) certain first band length 204 is woven in one layer and then, after a technical adjustment over a (pre) certain second band length 206, it is woven in two layers, in which the upper 210 and the lower fabric layer 208 results. This completes a shot report here. After a further technical adjustment, a (pre) determined first band length 204 is then woven in one layer and so on. In contrast to the exemplary embodiment described above, the warp and weft guide is controlled here in such a way that the "right" side of the webbing has two edges.
  • the belt strap 202 consists of a first, single-ply strap length 204 with two closed round edges RKG. a (adjoining) second, two-ply band length 206 with a closed round edge RKG and an open, divided round edge RKO, it being possible for a tubular, inflatable inlet 16 to be introduced from the open edge RKO of the two-ply band length 206.
  • FIG. 8 to 11 show a third exemplary embodiment, in which, as a modification to the second exemplary embodiment just described (FIGS. 5 to 7a), the two-ply band length 306 is followed by a third, single-ply band length 307 (for example in this case) with two closed round edges connects.
  • a third, single-ply band length 307 for example in this case
  • two layers can be woven in the middle third of the belt width for receiving a supply hose of an inlet 16, so that the configuration shown in FIG. 11 results.
  • FIG. 12 schematically shows an edge region of a webbing according to the invention, a hollow edge being shown in broken lines on the left side (in FIG. 12).
