Claims

1. An air bag covering for an air bag of a vehicle disposed inside a receptacle in an interior paneling comprising:
an opening flap which is connected with the interior paneling via predetermined breaking points when the air bag covering is in a closed state;
a hinge plate which includes a base element, is connected via a hinge plate, across an entire flat surface with the opening flap;
a deployment channel constructed as a frame part for the hinge plate, said frame part is connected with the hinge plate and together with the hinge plate forms a combination component, wherein the hinge plate has an expansion fold adjacent the base element and parallel to a hinge axis, wherein the hinge plate is displaceable toward a vehicle interior upon opening the air bag covering such that when the opening flap is opened, the hinge plate is moved linearly upwards along a vertical axis whereby the entire hinge axis is also moved upward and to thereby extend the expansion fold, wherein in the area of the expansion fold a damping element is provided for damping the movement of the hinge plate in a direction toward the vehicle interior, wherein the damping element is a cord.
2. The air bag covering of claim 1, wherein the expansion fold in the area between the attachment of hinge plate with the frame part and opening flap is preferably provided in proximity of the connection between the hinge plate and frame part.
3. The air bag covering according to claim 1, wherein the hinge plate is a sheet metal plate.
4. The air bag covering according to claim 1, wherein the hinge plate is at least from one of an elastic and fiber reinforced- or a textile reinforced plastic material.
5. The air bag covering according to claim 1, wherein the frame part is a sheet metal.
6. The air bag covering according to claim 1, wherein the frame part consists of at least one of an elastic and fiber reinforced- or a textile-reinforced plastic material.
7. The air bag covering according to claim 1, wherein the frame part comprises construction components, said components including angled profiles provided with lugs or bores.
8. The air bag covering according to claim 1, wherein the opening flap is an integral component of a dashboard, said dash board is configured as a backfoamed component.
9. The air bag covering according to claim 1, wherein the amount of the movement of hinge plate in direction of the vehicle interior corresponds with the unwound length of the expansion fold.
10. The air bag covering according to claim 9, wherein the unwound length of the expansion fold corresponds at least to the thickness of the entire assembly of the opening flap.
11. The air bag covering according to claim 10, wherein the hinge flap is configured as a striking plate for the air bag, and the base element of the hinge plate forms a part of the deployment channel.
12. The air bag covering according to claim 11, wherein between the hinge flap and the base element a hinge axis is configured in form of at least one of a bead, and an embossing.
