- care is taken to ensure that the cover is inserted flush into the recess in the body of the instrument panel.
- the recess of the body of the instrument panel is designed as a rectangular step and the support ring of the cover has a rectangular cross-section corresponding to the shape, it being possible to provide that in the recess of the body on the outer circumference of the body Instrument panel lying sealing lip is arranged. As a result, an almost gap-free seal is achieved, so that no material of the applied covering layer can get between the cover and the instrument panel. Visible dividing lines on the surface of the instrument panels are thus avoided.
- the recess of the body of the instrument panel forms an inclined surface that runs inward toward the recess
- the support rim of the cover has a correspondingly inclined support surface at its outer end, so that the obliquely tapering end region of the support rim is common forms a seal with the inclined surface of the body of the instrument panel.
- the cover has a web projecting inward behind the body of the instrument panel for connecting the cover to the module frame, the module frame being connected to the cover by means of a screw connection or alternatively a latching connection; other types of connection are possible.
- the module frame Since, according to the invention, no attachment is provided between the module frame carrying the airbag device and the body of the instrument panel, to divert the forces introduced by the airbag device into the module frame, it is provided that the module frame has a radially outward support which is connected to the cover Position of the module frame against the inside of the body of the instrument panel.
- the cover according to exemplary embodiments of the invention can have material weakenings adjacent to the support ring to form a hinge line and / or in the opening region of the cover to form a predetermined breaking line which defines the opening behavior.
- the airbag device can be fastened to the module frame
- the module frame has receptacles for fastening the airbag device
- the Airbag device can be attached to the module frame by means of a screw connection or alternatively a latching connection.
- the module frame is provided with a deformation of the stiffeners limiting it and / or that the module frame is designed as a firing channel for the unfolding gas bag.
- the invention provides for a reduction in the weight of the airbag device in that the airbag device has a deflector housing for receiving the folded therein Has gas bag and the deflector housing is fixed by means of a bracket which surrounds the outside of the airbag device and is fastened to the module frame.
- This has the advantage that there is no need for a separate module housing for the airbag device. Since the bracket provided assumes the fastening function for the airbag device on the module frame, the bracket can be made of cast metal or a correspondingly comparable plastic.
- the gas generator extends through the deflector housing and is fixed on both sides in the bracket that surrounds the deflector housing and is connected to the module frame, the bracket can cover and thus also seal the gas bag opening for inserting the deflector housing.
- the bracket contains end caps for fastening the gas bag and gas generator in the deflector housing and connects these parts to form an assembly.
- the cover is inserted into the recess from the front of the body of the instrument panel provided for receiving the cladding layer and is connected to the module frame opposite on the rear side of the body and thereby fixed in position and then the cladding layer is opened the body of the instrument panel is applied with the cover inserted into its recess, after which the airbag device is attached to the module frame.
- Fig. 1 shows an instrument panel in the cutout with integrated
- Fig. 2 shows the attachment of the cover to the body of the
- FIG. 3 shows an instrument panel according to FIG. 1 in a front view before the airbag device is triggered
- Fig. 4 shows the subject of Figure 3 immediately when the
- Fig. 5 shows the subject of Figures 3 and 4 in a first
- Fig. 6 shows the subject of Figures 3 to 5 with the gas bag unfolded.
- the instrument panel 10 held thereon in FIG. 1 has a body 11 with a recess recessed therein for receiving a cover 15 inserted into the recess of the body 11 for an airbag device held thereon.
- the body 11 and the cover 15 are covered by a uniform, without interruption applied covering layer 12, which consists of a foam 13 applied to the surface of the body 11 or the cover 15 and a decorative film 14 drawn over it.
- the edge of the body 11 of the instrument panel 10 enclosing the recess forms one from the surface with a rectangular cross-section recessed recess 17 in which a circumferential on the outer edge of the cover 15 and a correspondingly rectangular cross-section bearing ring 16 is received flush, so that body 11 and cover 15 form a continuous surface ,
- the cover 15 protrudes inward behind the instrument panel 10 with a web 18 to which a module frame 19 is fastened by means of a snap-in connection, which in the mounted position bears against the inside of the body 11 of the instrument panel 10 with a radially projecting support 20.
- the latching connection consists of latching hooks 21 attached to the web 18 and projecting outwards, which engage in correspondingly provided latching openings 22 in the module frame 19.
- the cover 15 is provided in the area adjacent to the support ring 16 with a material weakening which forms a hinge line 23;
- a predetermined breaking line 24 is formed in the cover 15 in the middle region of the cover 15, at which the cover 15 can open (FIG. 2).
- an additional sealing lip can be arranged on the outer circumference of the support ring 16 in order to seal the support ring 16 against the recess 17 in the body 11 of the instrument panel 10.
- a seal can also be realized, for example, in accordance with FIG. 2, in that the recess 17 of the body 11 is inwardly facing the recess forms inclined surface 26 and the support ring 16 of the cover 15 at its outer end ends in a corresponding inclined support surface 25, which acts as a sealing surface.
- an additional latching hook 21 is provided on the web 18 of the cover 15, which in the assembled state of the cover 15 latches on the body 11 of the instrument panel 10 behind the inner surface of the body 11 and thus the cover 15 on the instrument panel 10.
- FIG. 1 The design of the airbag device can also be seen in FIG. 1, which has a deflector housing 27 which is inserted into the gas bag via corresponding openings in the airbag fabric of the airbag 29, after which the airbag 29 encompassing the outer circumference of the deflector housing 27 extends inward into the deflector housing 27 is folded.
- the gas generator 28 is pushed into the deflector housing 27, so that the gas generator 28 with its blow-out openings 28a lies inside the gas bag 29.
- the deflector housing 27 is encompassed by an outer, U-shaped bracket 32, the U legs of which are fastened to the module frame 19 by means of fastening screws 35 on a bent portion 34 which is bent outwards.
- protective caps 30 are formed to fix the gas generator 28 on the bracket 32, furthermore plugs 31 for connecting the airbag device to the vehicle-side control.
- a protective film 33 is applied externally over the deflector housing with the gas bag fabric lying thereon.
- the gas generator 28 when the gas generator 28 is triggered, the gas escapes and thus acts on the deflector housing 27 and on the inside against the cover 15.
- the cover 15 consequently tears along the predetermined breaking line 24 so that the two halves of the cover 15 pivot outward about the hinge lines 23 and free the space for the airbag 29 to unfold.
- the gas bag 29 ensures a complete bending of the cover 15, including the cladding layer 12 carried by it. Due to the force acting laterally on the deflector housing 27 and over this on the web 18 of the cover 15 and also the module frame 19, the locking between the module frame 19 and Web 18 of the cover 15 reinforced via the snap connection used.
