Definitions
- the invention relates to an airbag device for a motor vehicle.
- Airbag devices have become known in a wide variety of embodiments and offer effective protection of a vehicle occupant in a vehicle accident.
- the invention has for its object to provide a preassembled, modular, active head protection (airbag) system for motor vehicles.
- the invention proposes an airbag device for a motor vehicle with an airbag consisting of an inflatable gas cushion and a gas generator
- Gas guide tube a profile strip with a firing channel formed therein, in which the airbag placed in stacked folds, in addition to
- Gas guide tube is included and fasteners for holding the existing profile, airbag and gas guide tube
- the profile strip with airbag and gas guide tube extends along one side of the vehicle from the A pillar to the C pillar and is in the transition area from the vehicle roof and one
- Vehicle side wall arranged on the vehicle body.
- the profile strip which receives the gas guide tube and the airbag within the firing channel can be a component which is simple in terms of production technology, in particular also inexpensive, in particular an injection molded plastic part made of a thermoplastic material such as PP, PP-EPDM, TPE or PVC.
- the gas guide tube should have a configuration following the body contour, which can be achieved in that the
- the fastening elements for the airbag device expediently consist of simple, on the profile strip or on the
- Pre-assembled body arranged in a row next to each other
- Brackets which should be made of plastic, but preferably of metal, such as spring plate.
- the folded airbag has a strap securing device which defines the guy line when the airbag is deployed.
- FIG. 1 shows a complete airbag device with a vehicle body indicated by thinner lines
- FIG. 2 shows a section, approximately following the line A-A in FIG. 1,
- Fig. 3 shows a section through the airbag device according to a first embodiment
- Fig. 4 shows a section through the airbag device according to a second embodiment.
- the new airbag device is a head protection module provided with the reference number 1, which is to be arranged in the transition area from the vehicle roof to each vehicle side wall in a manner which can be seen from FIGS. 1 and 2.
- the head protection module consists of a gas generator 2, an adapter 3 for establishing a connection between the gas generator 2 and a gas guide tube 4, a folded airbag 5 and a profile strip 13 formed with a firing channel 6.
- the airbag device extends from the A-pillar 14 (dashboard area ) to the C-pillar 15 and is adapted to the body course.
- the airbag device is by means of clips
- Retaining / guy straps 8 define a guy line 12.
- FIG. 1 shows a modified pillar covering 9 for the A pillar 14, a modified one Pillar trim 9 'for the C-pillar, a B-pillar trim 10 and a headliner 11 are shown.
- Fig. 3 shows a cross section of the airbag device and shows that the firing channel 6 is formed in a profile strip 13 which has a U-shaped cross section with two legs and a web connecting them.
- the profile strip 13 advantageously consists of a thermoplastic material and is created by injection molding or extrusion.
- An embedded scaffold belt 16 gives the profile strip 13 a rigidity which meets the technical requirements.
- the gas guide tube 4 and the airbag 5 stacked in folds are accommodated within the firing channel 6.
- the gas guide tube 4 sits in a divided area of the airbag, which can be formed by sewing. Blow-out openings, not shown, in the gas guide tube 4 are on the folded
- the legs of the profile strip 13 have beads 17 constricting the weft channel 6.
- the beads 17 are at
- the firing channel 6 is open.
- the folded airbag 5 is one
- shrink tube 18 which has a tear seam 19 in the region of the weft channel opening.
- the tear seam 19 is designed such that it opens at a certain filling gas pressure and the airbag 5 can deploy into the vehicle interior.
- the difference from that according to FIG. 3 is essentially that the firing channel 6 is closed by a sealing lip 20 and the airbag 5 is not surrounded by a shrink tube 18. So here the sealing lip 20 exerts an insulating effect on the filling gas generated. At a certain filling gas pressure, the sealing lip 20 can open, for example along a tear seam 21 formed therein.
- the sealing lip 20 can be formed at 22 on the profile strip 13, for example in the manner of a film hinge, and at 23 a joint connection, for example a clip connection, can be made with the profile strip 13.
- the inflated airbag comes between the head of a vehicle occupant and that adjacent to it
- the airbag device can, as shown in Fig. 2, from the Formhimmcl
- the headliner 11 can be covered, a predetermined kink 24 in the headliner 11 ensuring that an edge region 25 immediately releases the firing channel 6 when the airbag is deployed.
