Definitions
- the invention relates to an airbag attachment to a housing to be inserted into the airbag, the airbag having an opening for inserting the housing and after insertion of the housing into the airbag, this opening by turning over the wall parts of the airbag forming its border on the housing and by fastening this is closed.
- the invention relates to a method for fastening an airbag to a housing, which is inserted into an opening of the airbag, wherein after the housing has been inserted into the airbag, this opening by turning over the wall parts of the airbag forming its border onto the housing and through Attachment to this is closed.
- a gas bag attachment of this type is particularly required on gas bag restraint systems on the passenger side. These are equipped with a generally cylindrical gas generator which is inserted into a housing which keeps the wall of the gas bag at a distance from the gas generator and is provided with distributor openings for the gases generated by the gas generator.
- this housing is first inserted through the opening of the gas bag, whereupon the wall parts of the gas bag, which form the edges of the opening, fold over each other onto the housing and are fixed to the housing by means of a tensioning strip which is secured by a rivet connection is attached to the housing. Then the gas generator is pushed into the housing through a lateral opening of the gas bag. Finally, side bearing flanges are attached, which are fastened together with the inserted gas generator.
- the housing Since the opening for inserting the housing is formed between the overlapping wall parts of the gas bag, the housing cannot be inserted with a straight movement; rather, after the mutually overlapping wall parts have been spread apart, it must be pushed between them and then turned towards the interior of the gas bag.
- the insertion of the gas generator into the gas bag therefore requires increased skills, which makes assembly more difficult.
- the invention provides a gas bag attachment which considerably simplifies the assembly step for introducing the housing into the gas bag and also eliminates the need to sew together a plurality of fabric webs lying one above the other on the sides of the gas bag.
- the gas bag has a tubular fastening section, the inner circumference of which is adapted to the outer circumference of the housing; Furthermore, the opening is formed by the open end of the tubular fastening section.
- the housing can now be inserted directly into the opening at the open end of the tubular fastening section with a straight movement.
- the edge regions of the fastening section protruding beyond the housing are then preferably folded in the manner of a package packaging and folded over onto the housing, on which they are then held by a tensioning strip, which in turn is fastened by fastening pins anchored in the housing - 3 -
- Holes for the passage of the fastening pins are formed in the folded-over edge regions of the fastening section, which partially overlap one another.
- the method according to the invention for fastening a gas bag to a housing is characterized in that the gas bag is formed with a tubular fastening section, the inner circumference of which is adapted to the outer circumference of the housing, the opening being formed by the open end of the tubular fastening section that the housing is introduced essentially rectilinearly into the opening and is pushed so far into the fastening section that an edge region thereof protrudes beyond the housing and that this edge region is turned over onto the housing and fixed to it.
- Figure 1 is a perspective view of an airbag, a housing for receiving a gas generator and a clamping bar.
- 10 shows an enlarged partial section of the gas bag fastening
- 11 shows a perspective view of an airbag generator to be inserted directly into the airbag without a separate housing
- the gas bag shown in the expanded state in FIG. 1, generally designated 10, consists of a jacket part 10a and two side parts 10b which, like the jacket part 10a, merge into a fastening section 12.
- This fastening section 12 essentially circumscribes a rectangular shape, the inner circumference of which is adapted to the outer circumference of a housing 14, which serves to receive a (not shown) cylindrical gas generator and must be inserted into the interior of the gas bag 10.
- the open end of the fastening section 12 forms an opening 16, the border of which is rectangular.
- the housing 14 can be pushed into the opening 16 and into the fastening section 12 by a linear movement in the direction of an arrow F.
- FIG. 2 shows the state after the housing 14 has been introduced into the fastening section 12.
- an edge region 12a of the fastening section 12 projects beyond the housing 14.
- Holes 18 are made, for example punched out, in this edge region 12a, the arrangement and number of which is selected to match a number of fastening pins 20 which are anchored in the housing 14 and project therefrom.
- the edge region 12a is folded in the manner of a package packaging, the longer edge strips first being folded over against the housing 14.
- Fig. 2 shows the state after turning over one of the longer edge strips. Since the openings 18 are arranged to match the fastening pins 20, the edge strip at these holes 18 can be pushed over the fastening pins 20. The second longer edge strip is then also turned over and thereby overlaps the edge strip previously folded over, as shown in FIG. 3.
- the holes 18 in the superimposed edge strips are aligned with one another, and the fastening pins 20 protrude through both folded edge strips.
- the shorter edge strips which are folded into a triangular shape, are then folded over onto the longer edge strips which have already been folded over, the outer fastening pins 20 passing through the holes 18 lying one above the other.
- a clamping bar 15 which is provided with four through holes corresponding to the four fastening pins 20, is pushed onto the ends thereof, pressed against the folded-over edge regions of the fastening section 12 and fixed by means of screw nuts.
- the cylindrical gas generator is then inserted into the housing 14 through a lateral opening 22 in the fastening section 12 in the usual way.
- the main section of the gas bag 10 is assembled on the housing 14. folded as shown in Fig. 9.
- the assembly thus formed is then surrounded with a plastic sleeve 24, as is also shown in FIG. 9.
- the fastening pins 20a provided at one end with a head piece are inserted from the inside through openings in the wall of the housing 14.
- a spreading adhesive disk 26, preferably made of spring steel, is slid onto the smooth end of the fastening pins 20a which projects through the tensioning bar 15.
- FIG 11 shows a variant in which a separate housing (14 in the previously described embodiments) is omitted. Instead, a tubular gas generator 14a is provided, on which the fastening pins 20 are directly anchored. This gas generator 14a is inserted into the opening 16 of the fastening section 12 in the same way as the housing 14 in the previously described embodiments, and the gas bag is fastened to the gas generator 14a in the same way.
- the tensile strength of the gas bag attachment is increased.
- the edge regions 12a of the fastening section 12 are turned over onto the housing 14; mounting pins 20 and holes 18 are also provided.
- two further holes 18a are provided in the middle area and corresponding to the inner fastening pins 20.
- the edge region 12a is folded over again at 12b on the inner fastening pins 20, but only at one corner, so that the double-folded region 12b is triangular in each case.
- four fabric layers lie one above the other in the area of the inner fastening pins 20, as shown in FIG. 15.
- the tensile strength in the particularly highly stressed, central area can be increased by reinforcement layers 30 sewn on the inside.
