Abstract
A front airbag includes an outer sheath formed by a front wall and a circumferential wall, wherein a fixing portion for securing the front airbag tightly to the vehicle is provided on the circumferential wall, wherein the front wall constitutes an impact surface for a vehicle occupant and at a peripheral edge is circumferentially connected to a first portion of a peripheral edge of the circumferential wall. The length of the front wall peripheral edge is equal to the length of the first portion of the circumferential wall peripheral edge, and at least a second and a third portion of the circumferential wall peripheral edge are connected to each other.
Claims15
A passenger front airbag configured to be mounted in an instrument panel on a passenger side of a vehicle, comprising a front wall and a circumferential wall, wherein the circumferential wall comprises a fixing portion configured to secure the front airbag to the instrument panel in a mounted state of the front airbag so that the front airbag can receive inflation gas directed along a main inlet direction,
- wherein the front wall constitutes an impact surface for a vehicle occupant, the front wall having a peripheral edge connected to a first portion of a peripheral edge of the circumferential wall, wherein the length of the front wall peripheral edge is equal to the length of the first portion of the circumferential wall peripheral edge,
- wherein the circumferential wall peripheral edge comprises second and third portions that are connected to each other,
- wherein the front wall has a centerline that extends longitudinally between a lower end and an upper end of the front wall, the centerline being configured to extend vertically in the vehicle in an inflated condition of the front airbag,
- wherein the front wall has a non-mirror-symmetrical portion with respect to the centerline defined by a lateral bulge on one side of the front panel, the front wall having a mirror-symmetrical portion with respect to the centerline below the non-mirror-symmetrical portion, and
- wherein the circumferential wall comprises an inflation orifice formed by the fixing portion and through which inflation gas is directed in the main inlet direction, wherein the fixing portion is configured to lie along a fixing plane of the instrument panel in a mounted state of the front airbag, the fixing plane being transverse to an intersecting plane that extends across a center of the inflation orifice in the main inlet direction and intersects the fixing plane along a horizontal line, wherein the front wall and the circumferential wall are configured so that the mirror-symmetrical portion of the front wall is positioned longitudinally below the intersecting plane, facing the inflation orifice, and the mirror-symmetrical portion of the front wall receives the inflation gas flowing into the front airbag in the main inlet direction during deployment so that the forces of the inflation gas act uniformly on the front airbag.
