The airbag system for a motor vehicle extends below a dashboard and exhibits a generator housing, which is aligned in the transverse direction of the motor vehicle and which forms a blast channel for an airbag between integrated walls and adjoining separate face-sided walls. In load position at least one integrated wall of the blast channel can be displaced in the downward direction. In a first integrated channel wall of the generator housing a head impact element can be swiveled unilaterally in bearings; and in a starting position the head impact element can be suspended by means of a compression connection in the second integrated channel wall of the housing and can be disconnected in a load position. The connections can comprise semi-form-fit connections or springy connections.

1. An airbag system for a motor vehicle, the system comprising:a generator housing including, first and second integrated channel walls, and a head impact element pivotably mounted to the first integrated channel wall, the head impact element having a starting position and a load position, wherein in the starting position the head impact element is suspended in and connected to the second integrated channel wall by a connection, and in the load position the head impact element is disconnected from the second integrated channel wall wherein the head impact element comprises a U-shaped bow, the bow having a web element and two legs connected by the web element, the web element including an additional upper channel wall, and the legs being pivotably mounted on the first channel wall, wherein in the event of a load the additional upper channel wall of the head impact element pivots downwardly in relation to the stationary second channel wall from the starting position to the load position, thus disconnecting the connection, and wherein the web has a raised retaining crease, wherein the second integrated channel wall has an impressed receiving crease, wherein in the starting position the retaining crease engages the receiving crease to form the connection between the head impact element and the second integrated channel wall, and wherein in the load position the retaining crease is swung out of the receiving crease to disconnect the head impact element from the second integrated channel wall. 2. The system of claim 1, wherein the cross section of the receiving crease is W-shaped and has two stop creases, wherein the second integrated channel has an upper edge that is bent outwardly, and wherein at the starting position the retaining crease of the additional upper channel wall is held securely to rest against the receiving crease.3. The system of claim 1, wherein the edge of the receiving crease includes an upper stop, and the retaining crease includes a locked segment that is braced at the upper edge of the second integrated channel in the starting position.4. The system of claim 1, wherein the web element of the head impact element includes at least two separate installation suspension eyes, and wherein the retaining crease is between the suspension eyes and is aligned with the receiving crease so as to form fit.5. An airbag system for a motor vehicle, the system comprising:a generator housing including, first and second integrated channel walls, a head impact element pivotably mounted to the first integrated channel wall, the head impact element having a starting position and a load position, wherein in the starting position the head impact element is suspended in and connected to the second integrated channel wall by a connection, and in the load position the head impact element is disconnected from the second integrated channel wall, and angle brackets, which deformably connect the generator housing to a switchboard of the motor vehicle. 6. An airbag system for a motor vehicle, the system comprising:a generator housing including, first and second integrated channel walls, and a head impact element pivotably mounted to the first integrated channel wall, the head impact element having a starting position and a load position, wherein in the starting position the head impact element is suspended in and connected to the second integrated channel wall by a connection, and in the load position the head impact element is disconnected from the second integrated channel wall, wherein the head impact element comprises a U-shaped bow, the bow having a web element and two legs connected by the web element, the web element including an additional upper channel wall, and the legs being pivotably mounted on the first channel wall, and wherein in the starting position the second channel wall and the additional upper channel wall are arranged approximately in a common plane. 7. An airbag system for a motor vehicle, the system comprising:a generator housing including, first and second integrated channel walls, and a head impact element pivotably mounted to the first integrated channel wall, the head impact element having a starting position and a load position, wherein in the starting position the head impact element is suspended in and connected to the second integrated channel wall by a connection, and in the load position the head impact element is disconnected from the second integrated channel wall, wherein the head impact element comprises a U-shaped bow, the bow having a web element and two legs connected by the web element, the web element including an additional upper channel wall, and the legs being pivotably mounted on the first channel wall, and wherein in the load position the additional upper channel wall of the head impact element is braced against the second channel wall of the generator housing. 8. An airbag system for a motor vehicle, the system comprising:a generator housing including, first and second integrated channel walls, and a head impact element pivotably mounted to the first integrated channel wall, the head impact element having a starting position and a load position, wherein in the starting position the head impact element is suspended in and connected to the second integrated channel wall by a connection, and in the load position the head impact element is disconnected from the second integrated channel wall, and wherein the head impact element comprises a U-shaped bow, the bow having a web element and two legs connected by the web element, the web element including an additional upper channel wall, and the legs being pivotably mounted on the first channel wall; and face-sided brackets, wherein the generator housing is held on the face-sided brackets by fasteners, and the face-sided brackets are connected rigidly to a carrier of the motor vehicle body by bolted angle brackets, and wherein the legs of the head impact element reach from the outside over the face-sided brackets, and the legs and the brackets form complementary, joint face-side channel walls of the generator housing. 9. The system of claim 8, wherein the first and second integrated channel walls are made from aluminum extended parts.10. An airbag system for a motor vehicle, the system comprising:a generator housing including, first and second integrated channel walls, a head impact element including a web and two legs connected by the web, the head impact element further including a starting position and a load position, the web including a front channel wall having stops, the web further including an elastic spring element that is braced between the stops of the front channel wall and the second channel wall, and wherein in the load position the front channel wall of the head impact element is displaced and the spring element is elastically compressed. 11. A method of making an airbag system including a generator housing having first and second integrated channel walls, the method comprising:pivotably mounting a head impact element to the first integrated channel wall, wherein the head impact element has a starting position and a load position; and placing an elastic spring element between the head impact element and the second channel wall, wherein in the load position the head impact element is displaced and the spring element is elastically compressed.
