The invention describes a configuration for an airbag module behind the instrument panel of a motor vehicle. For this, a charge channel for the airbag is mounted on the back side of the instrument panel, while the airbag module is held by a support tube of the vehicle body. In this way, the charge channel loosely encompasses the airbag deployment opening of the airbag module. A catch on the charge channel acts in conjunction with a hook component fastened to the support tube in such a way that the bending of the instrument panel in the direction of the passenger compartment is limited when the airbag is deployed. In this manner, an orderly unfolding of the airbag occurs. Additionally, the separate configuration of the charge channel and the airbag module is not susceptible to component tolerances.

L'invention concerne un agencement d'un module de coussin gonflable (7) derrière le tableau de bord (1) d'un véhicule automobile. Selon l'invention, un conduit d'injection (5) pour le coussin gonflable est fixé sur l'envers du tableau de bord alors que le module de coussin gonflable (7) est maintenu par un tube support (9) de la carrosserie du véhicule. Le conduit d'injection (5) entoure lâchement l'ouverture de sortie du coussin gonflable du module de coussin gonflable. Un élément d'arrêt (6) sur le conduit d'injection (5) coopère avec un élément crochet (11, 11a) fixé sur le tube support de façon que le bombement du tableau de bord (1) vers l'habitacle est maintenu dans des limites lors de l'amorçage du coussin gonflable. Cela assure un déploiement correct du coussin gonflable. En outre, la disposition séparée du conduit d'injection et du module de coussin gonflable n'est pas sensible aux tolérances des composants.
