Abstract
An airbag module for an automotive vehicle is disclosed. The airbag module comprises a folded inflatable airbag, a fastening element for mounting the airbag on the vehicle, a mounting jacket in which the folded airbag is received and fixed, as well as an elongate flexible holding strap for positioning the airbag in its deployed inflated state. The holding strap extends from a first strap end fastened on the airbag to an opposite second strap end to which the fastening element is attached. In the folded state of the airbag, the holding strap is connected to the mounting jacket or is received in the mounting jacket.

An airbag module for an automotive vehicle, comprising a folded inflatable airbag, a fastening element for mounting the airbag on the vehicle, a mounting jacket in which the folded airbag is received and fixed, an elongate flexible holding strap for positioning the airbag in a deployed inflated state, the holding strap extending from a first strap end fastened on the airbag to an opposite second strap end to which the fastening element is attached, wherein in a folded state of the airbag, the first strap end of the holding strap is fastened on a portion of the airbag that is positioned within the mounting jacket, wherein when the airbag is in the deployed inflated state, the holding strap is tensioned between the first strap end and the fastening element and stretched over a free strap length, wherein the mounting jacket is an elongate mounting tube extending along a longitudinal axis and having a largely constant tube cross-section, wherein the mounting tube includes a circumferential wall that includes at least two radial openings formed therethrough, wherein when the holding strap is in the folded state the holding strap is threaded through the openings so that the holding strap is folded at least once within the mounting jacket for reducing the free strap length.
An airbag module for an automotive vehicle, comprising:
- a folded inflatable airbag,
- a fastening element for mounting the airbag on the vehicle,
- a mounting jacket in which the folded airbag is received and fixed, wherein the fastening element is connected to the mounting jacket,
- an elongate flexible holding strap for positioning the airbag in a deployed inflated state, the holding strap extending from a first strap end fastened on the airbag to an opposite second strap end to which the fastening element is attached,
- wherein in a folded state of the airbag, the holding strap is connected to the mounting jacket or is received in the mounting jacket
- wherein the fastening element and the mounting jacket include corresponding mounting holes for receiving a mounting bolt which secures the mounting jacket and the fastening element to the vehicle.
An airbag module for an automotive vehicle, comprising a folded inflatable airbag, a fastening element for mounting the airbag on the vehicle, a mounting jacket in which the folded airbag is received and fixed, an elongate flexible holding strap for positioning the airbag in a deployed inflated state, the holding strap being separately configured and connected and extending from a first strap end fastened on the airbag to an opposite second strap end to which the fastening element is attached, wherein in a folded state of the airbag, the first strap end of the holding strap is fastened on the airbag that is positioned within the mounting jacket such that the holding strap is received in the mounting jacket and folded at least once in the mounting jacket for reducing a free strap length and wherein in the deployed inflated state of the airbag, the holding strap is tensioned between the first strap end and the fastening element and stretched over the free strap length;
- wherein the mounting jacket is an elongate mounting tube extending along a longitudinal axis and having a largely constant tube cross-section which includes a tube end portion having a reduced tube cross-section at least at one axial end, and wherein the second strap end extends into the tube end portion and a portion of the holding strap is received in the mounting tube adjacent the tube end portion;
- wherein the fastening element is connected to the mounting jacket and wherein the fastening element and the mounting jacket include corresponding mounting holes for receiving a mounting bolt which secures the mounting jacket and the fastening element to the vehicle.
An airbag module for an automotive vehicle, comprising a folded inflatable airbag, a fastening element for mounting the airbag on the vehicle, a mounting jacket in which the folded airbag is received and fixed, an elongate flexible holding strap for positioning the airbag in a deployed inflated state, the holding strap extending from a first strap end fastened on a portion of the airbag to an opposite second strap end to which the fastening element is attached, wherein the mounting jacket is an elongate mounting tube extending along a longitudinal axis and having a largely constant tube first cross-section, and a tube end portion extending along the longitudinal axis that tapers inwardly toward the longitudinal axis to a largely constant tube second cross-section at least at one axial end that is smaller than the first cross-section, and wherein the airbag is positioned within the first cross-section when in a folded state, and the second strap end extends into the tube end portion and the holding strap is folded upon itself in a tapered section disposed between the first cross-section and the second cross-section reducing a free strap length when the airbag is in the folded state, and the second strap end extends into the second cross-section;
- wherein when the airbag is in the deployed inflated state, the holding strap is tensioned between the first strap end and the fastening element and stretched over the free strap length.
