Definitions

  • the invention is concerned with an airbag module in accordance with the pream- ble of Claim 1 as well as with an assembly process in accordance with Claim 17.
  • Most front airbag modules in particular driver front airbag modules, have a cover made of plastic with a roof section and a side wall section extending from the roof section, a base plate, a gas generator supported by the base plate, and an airbag.
  • the base plate is connected to the side wall section.
  • the airbag's inflation opening is usually held in the area of the gas generator at a flange of the gas generator or at the base plate.
  • the inflation opening usually has to be strengthened and for which purpose a retainer ring is usually provided in the air- bag.
  • the category-defining DE 44 25 495 A1 proposes an airbag module in which the airbag is held in clamped fashion between the base plate and the side wall section.
  • the base plate extendeds in sections around a bottom end of the side wall section in order to form an outer clamping section in this way.
  • the base plate must be a very complicatedly shaped bent sheet metal part; assembly takes place through plastic deformation of sections of this base plate. Both the production of the base plate and the assembly of the airbag module are relatively expensive.
  • the present invention is concerned with the problem of improving an airbag module of this type such that its individual parts are easy and cost effective to produce and that its assembly is very simple and is automatable to a high degree.
  • a separate external clamping ring is provided that is not connected in one piece with either the side wall section or with any base part that may be present.
  • This separate external clamping ring can be brought from an assembly position into an end position by an axial movement.
  • the assembly position is preferably closer to the roof section of the cover than the end position.
  • the external clamping ring can be an injection-moulded plastic part.
  • the assembly is also greatly simplified by the fact that the external clamping ring is not connected to a component that lies on the inside of the cover.
  • An additional advantage is that a base part (base plate) can be present but does not have to be. It is namely possible to use a section of the airbag instead of a base part, which leads to a reduction in weight.
  • An additional advantage is that the external clamping ring can also be used for the assembly of the airbag module to a steering wheel. The forces that are transmitted on the expansion of the airbag - and in particular because of the bag slap - from the airbag module to the steering wheel are in this case transmitted through the external clamping ring into the steering wheel.
  • An additional advantage is that the airbag module can be easily designed such that the forces that take effect on the bag slap lead to a strengthening of the clamping, so that there is no danger that the airbag will separate.
  • Figure 1 shows all individual parts of a first embodiment of the airbag mod- ule in accordance with the invention in a non-assembled state
  • FIG. 1 shows what is shown in Figure 1 after two first assembly steps have been carried out
  • Figure 3 shows what is shown in Figure 2 after a further assembly step has been carried out
  • Figure 4 shows what is shown in Figure 3 after completion of the assembly of the airbag module
  • Figure 4a shows a variant of what is shown in Figure 4,
  • Figure 5 shows what is shown in Figure 4 after the airbag module has been mounted in a steering wheel
  • Figure 6 shows a second example of the first embodiment of the invention in a greatly schematised partial view, wherein the airbag module is in an assembly state corresponding to Figure 2,
  • Figure 7 shows what is shown in Figure 6 in an assembly condition corresponding to Figure 3
  • Figure 6 shows what is shown in Figure 6 in an assembled condition corresponding to Figure 4
  • FIG. 14 shows a cross section along plane A-A in Figure 14, shows a second embodiment of the airbag module in accordance with the invention in a representation corresponding to Figure 1 , shows what is shown in Figure 16 after a first assembly step has been carried out (corresponds basically to Figure 2), shows what is shown in Figure 17 after a further assembly step has been carried out,
  • FIG. 1 shows all individual parts of a first embodiment of the airbag module in accordance with the invention.
  • the airbag module has a cover 10, an external clamping ring 30, an inside clamping ring 24, an airbag 20, a rigid base part 40 and a gas generator 44.
  • the gas generator 44 is firmly connected to the base part 40, as shown in Figure 1 (as already mentioned). It would also be possible to design the gas generator and the base part as a single component, in particular in such a way that the base part is a large gas generator flange.
  • the cover 10 has a roof section 12 and a circumferential side wall section 14 extending from the roof section 12 in an axial direction. So, the cover 10, which is preferably an injection-moulded part made of plastic, forms a type of pot.
  • the side wall section 14 forms preferably a ring with an essentially circular cross-section.
  • the side wall section 14 has an outer contour 16 and an inner contour 18.
  • the inner contour 18 forms a groove with a horizontal surface section 18a and a surface section 18b running upwards.
  • the outer contour has a first upward pointing surface section 16a and a wedge adjacing the first upward pointing surface section 16a in the direction of roof section 12.
  • the wedge has a downwards pointing surface section 16b and a second upwards pointing surface section 16c.
  • “pointing upwards” and “pointing downwards” means pointing slantwise upwards or downwards respectively, so that the respective surface normals have an axial and a radial portion.
  • the first upwards pointing surface section 16a is basically opposite the inner contour 18, wherein the upwards pointing surface section 18b of the inner contour 18 and the first upwards pointing surface section 16a of the external contour 16 extend parallel to one another.
  • the lower edge region of side wall section 14 has a coning section 14a, wherein the corresponding cone tapers upwards.
  • upwards means “in the direction of the roof section”.
  • the lower edge region can have slits extending in radial direction in order to increase the elasticity of this region.
  • the coning section 14a is divided into several sections.
  • the external clamping ring 30 has a ring rail with an essentially V-shaped cross- section with an inner leg 32 and an outer leg 34.
  • a surface 32a of the external clamping ring 30 that points inwards is inclined and dimensioned in such a way that it can be brought to rest on the upwards pointing surface section 16a of the external contour 16, as will be seen below.
  • the external clamping ring 30 has an upwards pointing surface 32b, which is inclined and dimensioned in such a way that it can be brought to rest on the downwards pointing surface sec- tion 16b of external contour 16; this will also be seen below.
  • the inside clamping ring 24 is shaped and dimensioned so that it fits into the inside contour 18 together with an outer edge of the base part 40. For this purpose it has an outwards pointing surface 24a. In addition, the inside clamping ring 24 has an indentation 26 on the inside.
  • the inside clamping ring 24 is also preferably an injection-moulded plastic part.
  • the base part 40 which can be designed as a sheet metal or plastic part, has an upwards extending ring-shaped protrusion 42, which extends in an assembled state into the indentation 26 of the inside clamping ring 24, which will soon be seen with regard to Figure 2.
  • the base part 40 also has a central opening, through which the gas generator 44 projects into the inside of the airbag 20. Fi- nally, a ventilation opening 43 is provided between the ring-shaped protrusion 42 and the central opening for the gas generator 44.
  • Figure 2 shows what is shown in Figure 1 after two initial assembly steps that are independent of each other have been carried out:
  • the external clamping ring 30 has been pushed onto the side wall section 14, wherein it is held in place by the second upwards pointing surface sections 16c of external contour 16.
  • the lower area of side wall section 14 and/or the external clamping ring 30 must have a certain amount of elasticity, for which purpose, as already mentioned, radial slits can be provided in the lower edge region of side wall section 14.
  • the airbag 20 has been attached to the base part 40 by means of the inside clamping ring 24, wherein an edge of the airbag 20 is clamped between the inside clamping ring 24 and the ring-shaped protrusion 42.
  • this clamping would be insufficient to hold the airbag 20 at the base part 40 when the airbag is filled.
  • Figure 3 shows a subsequent assembly state.
  • the airbag 20 has been folded into the cover 10 and the base part 40 has been slid into the side wall section 14 together with the inside clamping ring 24 until an outer edge of the base part 40 and the outward pointing surface 24a of the inside clamping ring 24 came to lie in the inner contour 18.
  • the external clamping ring 30 is pushed downwards in a radial movement (that is, away from roof section 12) until the status shown in Figure 4 is reached.
  • the outer leg 34 of the external clamping ring 30 can be used together with not shown, in axial direction operating horn springs to hold the airbag module on retaining parts 50 on the steering wheel side.
  • the force path that leads from the airbag 20 into the retaining parts 50 on the bag slap can be seen directly in Figure 5. It can also be seen directly in Figure 5 that when the bag slap occurs the clamping force of the external clamping ring 34 on the side wall section 14, and thus the clamping force of the side wall section 14 on the inside clamping ring 24 and the base part 40, is increased; this means that the clamping force is increased when it is required, so that loosening of the airbag 20 from the side wall section 14 is ruled out.
  • the inside clamping ring 24 serves as an inside clamping part.
  • FIG 4a shows a variant in which the ventilation opening 43 is a part of a Venturi nozzle.
  • an air conducting element 43a is located on the inside of the base part 40 and forms a Venturi tube together with a section of the base part.
  • Said Venturi tube has its smallest diameter at the position of the ventilation opening 43.
  • One face side of the Venturi tube points towards an outlet opening 44a of the gas generator 44, the other face side towards the inside of the airbag.
  • the ventilation opening 43 does not serve for the ventilation while the airbag is deployed; on the contrary, additional external air is sucked in. After the gas generator 44 has burned out the ventilation opening 43 is used for ventilation.
  • FIGS. 6 to 8 show a variant of the example just described, wherein only one part of the airbag module is illustrated.
  • inner contour and outer contour are formed as inner groove 18d and outer groove 16d opposing each other, wherein each of the two grooves has a basically rectangular cross-section.
  • the second difference is that the airbag 20 is not directly clamped between the side wall section 14 and the base part 40 that serves as inside clamping part but indirectly, because the lower edge of the airbag 20 is held completely between the inside clamping ring 24 and the base part 40.
  • the inside clamping ring 24 is not used as an inside clamping part but as a force transmission element between the side wall section 14 and the rigid base part 40.
  • FIGs 9 to 13 show how the airbag module described above can be assembled fully automatically by means of an automatic assembly machine 60.
  • This auto- matic assembly machine 60 has a ring-shaped stationary element 62, a vertically movable element 64 held in the central opening of the stationary element 62, first horizontally movable elements 66a, 66b located above the stationary element 62 and second horizontally movable elements 68a, 68b with wedge-shaped projections 69a and 69b located above these first horizontally movable elements.
  • a holding element 70 illustrated in Figures 12 and 13 only).
  • Figure 9 shows an initial assembly state in which the airbag 20 is fastened to the base part 40 by means of the inside clamping ring, wherein the gas generator 44 is already mounted at the base part 40.
  • This assembly state corresponds to what is shown in the lower part of Figure 6.
  • the automatic assembly machine 60 is in a state in which the vertically movable element 64 is in its lowest position, the two first horizontally movable elements 66a, 66b are open, and the second horizontally movable elements 68a, 66b are closed. First of all ( Figure 7) the two first horizontally movable elements 66a, 66b are closed. By this movement the airbag 20 is compressed and thus packed.
  • the first two horizontally movable elements 66a, 66b each have a semicircular recesses pointing towards each other, so that in the closed state of Figure 10 a cylindrical packing space for the airbag 20 is formed.
  • the two second horizontally movable elements 68a, 68b are now opened ( Figure 1 1 ). Following this, the cover 10 is positioned above the packed airbag 20 by means of the holding element 70 and lowered towards the horizontally movable elements 66a, 66b.
  • FIGs 14 and 15 show a third example of the first embodiment.
  • the external clamping ring 30 is also used for the assembly of the airbag module in a steering wheel body.
  • the external clamping ring has lugs 36 each with an opening 36a that can latch in corresponding hook elements of the steering wheel body (not illustrated) by means of their contact surfaces 36b.
  • the lugs extend downwards, so that the connection of the airbag module at the steering wheel body can take place at the level of the gas generator or under the gas generator.
  • the area of the side wall section 14 in which the clamping takes place is practically without contours here, as can be seen in Figure 15.
  • the airbag 20 is clamped directly between the side wall section 14 and the base part and between the base part 40 and the inside clamping ring 24.
  • protrusions 15 extend from the side wall section 14 to the inside that define the assembled position of the inside clamping ring 24 and that can transfer forces on the occurrence of the bag slap.
  • snap-in noses 30a extend from the latter into corresponding lock-in recesses 17 of the side wall section 14. All three previously described examples is in common that the side wall section 14 and the inside clamping ring 24 only have to transfer pressure forces, so this components can be made from cost-effective unreinforced plastic material.
