Definitions

  • the invention relates to an airbag device according to Claim 1.
  • cover element which is visible from the direction of the occupants of the vehicle. This is the case, in particular, with front airbag modules for the driver and the passenger.
  • the aforementioned cover element is generally the hub region of the steering wheel.
  • the cover element may be fastened to the housing of the airbag module or to a sub- assembly fixed to the vehicle.
  • non-axial positioning elements between a component of the airbag module and a component fixed to the vehicle.
  • These non-axial positioning elements may, in particular, consist of pins and holes corresponding thereto.
  • the axial positioning of the cover element relative to the component fixed to the vehicle may in this case be undertaken by separate sub-assemblies.
  • a positioning relative to three degrees of freedom namely two translational degrees of freedom and one rotational degree of freedom, has to be achieved by the pins and corresponding holes.
  • two pins and two holes are sufficient.
  • FIG. 13 shows a steering wheel 30 comprising an airbag module in a plan view.
  • the airbag module has a cover element 16 which almost covers the entire hub region and is directly or indirectly connected to a steering wheel body (component fixed to the vehicle).
  • Two pins 17 and 18 rigidly connected to the cover element serve for positioning the cover element 16 relative to the steering wheel body.
  • These pins 17, 18 are designed, for example, as cylinders and have a circular cross section.
  • the first pin 17 is in this case held in a round hole and defines the position of the cover element 16 relative to the steering wheel body in the two translational degrees of freedom, namely in the X- and Y- directions.
  • the second pin 18 only has to define one degree of freedom, namely the rotational degree of freedom, so that it is held in a slot 20.
  • Gaps S1 , S2 and S3 are located between the cover element 16 and the spokes of the steering wheel body.
  • the second pin 18 may move in its slot 20 in a translatory manner, namely in the direction of the longitudinal extension of the slot 20 (in this case the Y-direction), so that the expansion of the cover element 16 is not hindered.
  • a displaced position 18' of the second pin is illustrated by dotted lines in Figure 13.
  • the pins 17, 18 have to be located substantially at the edge of the cover element 16. This has, however, the result that the upper edge 16a of the cover element 16 in practice remains in position whilst the lower edge 16b is considerably displaced, as in this case the entire longitudinal alteration in the Y- direction is added to the movement of the lower edge 16b. It is understood that the position of the second pin 18 in this direction alters substantially twice as much as the position of the central point M. This has the result that the size of the lower gap S3 alters to a greater extent than the size of the lateral gaps S1 , S2.
  • the alterations of the gap sizes ⁇ S1 , ⁇ S2, ⁇ S3 are also illustrated in Figure 13 as is the alteration to the position of the central point of the (M, M 1 ) of the cover element 16.
  • an airbag module which is positioned on the steering wheel body by means of pins on the base of the airbag module and associated holes in the steering wheel body and after the positioning has been carried out is screwed rigidly thereto.
  • the pins are held displaceably on the housing base in the non-axial direction and are locked in position on the housing base before final assembly on the steering wheel body.
  • a jig is used for the alignment.
  • the pins may not be used for compensating for contraction or expansion processes.
  • the object of the present invention is to provide an airbag device for a motor vehicle in which, as a whole, a small and uniform gap size is achieved between the cover element of the airbag module and the surface surrounding the cover element.
  • the positioning means which position the first component relative to the second component therefore, comprise a pin arranged on a component (for example the airbag module) with a pin length and a pin width and an associated slot arranged on the other component (for example the steering wheel body) and extending along a longitudinal axis, with a hole width and a hole length exceeding the hole width.
  • the pin width substantially corresponds to the hole width and the pin length is less than the hole length so that during the expansion or contraction of the positioned component of the airbag module, due to environmental effects, ageing processes or production influences the pin is exclusively displaced along the longitudinal axis of the slot.
  • the position of the pin relative to the first component may be altered in a non-assembled state and only locked in position in the assembled state by means of a locking means.
  • the positioning means has a dual function: firstly it compensates for production tolerances during final assembly and secondly compensates for contraction and expansion processes which may occur over the entire life of the airbag device.
  • each pin-slot pair defines just one degree of freedom. By this measure it may be achieved that the gap width during expansion/contraction alters very uniformly.
  • the longitudinal axes of the slots meet at a point of intersection which is additionally located preferably in the vicinity of the point which is defined by the projection of the geometric central point of the positioned component into the plane of the longitudinal axes, the direction of projection being perpendicular to the plane of the longitudinal axes.
  • the component of the airbag module to be positioned consists of a material which, as such, is isotropic, in particular a thermoplastic produced by an injection-moulding method. If the isotropy relative to the component is provided in a precise manner, it is therefore to be assumed that a possible expansion or contraction also takes place in an isotropic manner, i.e.
  • the airbag device is a front airbag device for the driver of a motor vehicle, with an airbag module being arranged in a steering wheel body.
  • the side walls of the slots and/or the pins are of convex configuration.
  • a preferred option to arrange the pin on the first component consists in providing a pin screw which is eccentric relative to the pin. This is, on the one hand, mechanically simple and has the further advantage that when aligning the pin only one degree of freedom is available to said pin, which simplifies the final assembly.
  • the pin screw may in this case extend through an eccentric bore of the pin or be arranged completely outside the pin.

  • the springs 24 generally spiral springs, are neither able to position the airbag module accurately in the axial direction nor in the non-axial direction relative to the steering wheel body, positioning means have to be present which undertake this task.
  • the axial positioning means and the non-axial positioning means are completely separated from one another.
  • pins 17, 18, 19 and associated slots 20, 21 , 22 serve as non-axial positioning means.
  • Figure 1 shows a steering wheel in a plan view, the non-axial positioning elements which respectively consist of a pin 17, 18, 19 and a slot 20, 21 , 22 being shown, although they might not be visible in this view.
  • the remaining non- visible components such as the airbag housing, airbag and gas generator are not shown for the sake of clarity.
  • the pins 17, 18, 19 are cylindrical with a circular diameter, so that the pins may be characterised by their diameter d. (In other words, the length and the width of the pins are identical).

The length I L of the slots is, however, greater than the diameter d of the pins.
  • a pin 18 in its slot 20 in the plane which is perpendicular to the steering column (X-Y plane), this being the drawing plane in Figure 1 has just one degree of freedom, namely a translational degree of freedom along the longitudinal axis A1 , A2, A3 of the respective slot 20, 21 , 22. This also does not alter with the axial movement of the cover element 16 or a part thereof in the Z- direction.
  • the axes A1 , A3 of the two slots 20, 22 are congruent. As is revealed from Figure 1 , the axes A1 , A2, A3 relative to the drawing plane meet substantially in the central point M of the cover element 16.

  • This steering wheel unit has a steering wheel body 23 which has a recess 28 in the hub region. Spokes 30 extend from the hub region.
  • the steering column 32 extends approximately centrally from the hub region. The direction of extension of the steering column 32 defines the axial direction or Z-direction hereinafter.
  • the plane which is perpendicular to this Z- direction (this plane is therefore also the drawing plane of Figure 1) is the XY- plane.
  • a fastening plate 34 is screwed to the steering wheel body 23 by means of screws 36, i.e. is rigidly connected to it. It is also possible that the fastening plate is an integral part of the steering wheel body; this option may assist in reducing tolerances and production costs. According to the definitions chosen in this application, the fastening plate 34 and all components which extend therefrom, are considered as being part of the steering wheel body.

  • the housing base 14b of the housing 14 is connected via springs 24 to the fastening plate 34, so that the airbag module 5, i.e. in particular the housing 14, may be pressed down against the force of these springs 24 in the axial direction against the steering wheel. If the airbag module 5 is pressed down sufficiently far, the horn contacts 26 are closed.
  • the steering wheel body, airbag module and the springs acting between these components together form the steering wheel unit.
  • the springs 24 are naturally not able to define accurately the position of the airbag module 5 relative to the steering wheel, so that positioning means have to be provided.
  • the airbag module has 6 degrees of freedom relative to the steering wheel (three translational degrees of freedom and three rotational degrees of freedom) so that the positioning means have to be correspondingly designed. If, for each possible direction of movement, just one positioning means is provided, 6 positioning means are required.
  • Each positioning means consists of two parts, namely a part on the steering wheel side and a part on the module side.
  • Figure 2 shows two positioning means, which are respectively used for axial positioning, i.e. the positioning in the Z-direction and two positioning means, which serve for the non-axial positioning of the airbag module.
  • Each of the axial positioning means has an axial positioning hook 40 as axial positioning means on the steering wheel side and an axial positioning projection 42 as axial positioning means on the module side. Only two axial positioning means are shown by the sectional views. In practice, however, generally three thereof are present.
  • the springs 24 press the housing 14 upwards and thus the axial positioning projections 42 extending from the housing from below against the axial positioning hooks 40 so that the axial position (Z-position) of the module is entirely determined thereby.
  • the airbag module 5 may be pressed down in a precisely axial manner for actuating the horn or it may also be pressed down in a tilted manner.
  • the object of the axial positioning means is exclusively in the axial positioning, and said means do not have to withstand very large forces.
  • the relevant components may be produced from plastics material, and, in particular, the axial positioning means on the module side may be made integrally with the housing.
  • the retaining means contain retaining means on the steering wheel side, in this case namely retaining hooks 44, and retaining means on the module side, in this case namely retaining projections 46.
  • the retaining means are non-operational in the normal operating state, i.e. when no external force acts on the airbag module or when the airbag module is pressed down for actuating the horn.
  • the retaining means on the steering wheel side (retaining hooks 44) and the retaining means on the module side (retaining projections 46) do not come into contact with one another.
  • the retaining means are not in competition with the axial positioning means, and fewer requirements for their dimensional accuracy have to be set.
  • the retaining means entirely or partially of metal.
  • pins 17, 18, 19 and slots 20, 21 , 22 serve for the non-axial positioning of the cover element 16 relative to the steering wheel body 23.
  • the pins extend from the airbag module, in the embodiment shown from the housing into the slots 20, 21 , 22 which are allocated to the steering wheel body 23. It might, however, also be possible, in particular, for the pins to extend from the cover element.
  • the pins are not integrally configured with the housing 14 but connected thereto by means of a pin screw 50, for which purpose the housing has a nut 52 and the pin 17 has a through-bore 54.
  • the pin 17 is a rotational body, in the embodiment of Figure 3 a cylinder with chamfered lower edge.
  • the through-bore 54 extends parallel to the axis R of the rotational body, but offset thereof, and is therefore arranged eccentrically.
  • the pin 17 may be rotated about this pin screw 50 and, due to the eccentricity of the screw relative to the rotational axis of the pin, the position of the peripheral surface of the pin alters relative to the housing during rotation and thus also relative to the cover element of the airbag module.
  • the pin 17 has in this state, therefore, exactly one degree of freedom relative to the housing 14.
  • By tightening the pin screw 50 the position of the pin relative to the housing is secured and the pin 17 is then rigidly arranged relative to the housing 14.
  • the pin screw thus serves as a rotary axis and as locking means.
  • Figure 4 shows an alternative embodiment to that shown in Figure 3.
  • the housing has a cone which projects into the through-bore, which to this end has a conical portion.
  • the two other pins 18 and 19 are of identical construction to the pin 17 and fastened to the housing 14.
  • the position of the pins relative to the housing is fixed in a final assembly step when producing the airbag module.
  • the airbag module is inserted into a jig, which has slots which exactly correspond to the position of the slots of the steering wheel type, into which the airbag module is intended to be fitted, and a template which establishes the ideal position of the cover element.
  • the geometry between the template and the slots is accurately defined.
  • the pins are respectively rotated into a position which compensates for possible production tolerances. In this position, the pin screws 50 are tightened, so that a rigid connection is established between the pins and the housing.
  • Figure 5 is substantially a slightly enlarged view of Figure 1.
  • the pins are illustrated in their ideal position in continuous lines, which they have obtained by using the above described jig.
  • the positions which they could have if their position were not adjustable are shown (in an exaggerated manner) in dotted lines.
  • the pin screws 50 are also shown. It is obvious that in the event of non- alignment, a non-uniform gap size SP would be produced. A very uniform gap size results at the time of assembly from the adjustability of the pins.
  • the geometry of the slots ensures, in cooperation with the pins rigidly connected to the housing from the time of final assembly, that this uniform gap size is also maintained over the life of the airbag device, even when due to environmental influences or ageing processes, expansions or contractions occur:
  • Figure 6 shows the geometry of Figure 2, the pins 17, 18, 19 being shown respectively in an aligned initial position and in an extended position 17', 18', 19'.
  • the point of intersection S of the longitudinal axes of the slots is seen to be slightly outside the exact central point M of the cover element 16, but not far removed therefrom. It is recognised that on expansion the cover element 16 the pins are displaced in the respective axial directions of their slots, said displacements being substantially of the same amount for all pins. If the point of intersection S does not exactly coincide with the central point M, the central point M of the cover element 16 is slightly displaced.
  • Figure 7 shows an alternative to that shown in Figure 6.
  • all longitudinal axes A1 , A2, A3 of the slots 20, 21 , 22 are different from one another and, also in this case, intersect at a point of intersection S which is located directly adjacent to the central point M of the cover element 16.

  • the pin screw 50 does not extend through an asymmetrical bore of the pin 17, 18, 19 but is entirely located outside the pin 17, 18, 19, which is also in this case rotationally symmetrical, namely in the form of a cylinder with a chamfered lower edge.
  • the pin screw 50 located outside the pin is also in this case parallel to the rotational axis R of the pin, and is therefore also arranged eccentrically.
  • a projection 60 widening to form a screw connection 60 serves for the connection between the pin and housing 14.
  • a conical portion 64 of the housing 14 which bears a nut 52 projects into the screw connection 60.

If the capacity for altering the position of the pins, however, is achieved in a different manner, it might also be possible to provide pins which are not rotationally symmetrical, for example with an oval cross section. Due to the generally very small pivoting angles which occur in the second embodiment, in some applications it may also be possible to use pins which are not rotationally symmetrical.

Abstract

L'invention concerne un dispositif airbag destiné à un véhicule à moteur, comprenant une premier composant doté d'un élément de recouvrement (16) pour un logement d'airbag, un deuxième composant fixé sur le véhicule et un moyen de positionnement destiné à placer le premier composant sur le deuxième composant. Le moyen de positionnement comprend au moins une tige (17, 18, 19) disposée rigide, dans l'état assemblé, sur un des deux composants. Cette tige présente une longueur (d) et une largeur (d). Le moyen de positionnement comprend également une fente associée (20, 21, 22) formée sur l'autre composant et s'étendant le long d'un axe longitudinal (A1, A2, A3). Cette fente présente une largeur de trou (bL) et une longueur de trou  (IL) supérieure à ladite largeur (bL). La largeur de tige (d) correspond sensiblement à la largeur de trou (bL) et la longueur de tige (d) est inférieure à la longueur de trou (IL), de sorte que, lors de l'extension ou de la rétraction du composant positionné du module airbag, du fait des effets environnementaux, des processus de vieillissement ou des influences de production, la tige soit déplacée exclusivement le long de l'axe longitudinal (A1, A2, A3) de la fente (20, 21, 22). Pour obtenir de petits écartements réguliers, la position de la tige par rapport au premier composant peut être modifiée dans l'état non assemblé et bloquée dans l'état assemblé.
