## Abstract

The invention relates to a covering assembly over the chute channel of an airbag comprising having an airbag through-opening, which is closed by an airbag flap and an, in particular sprayed-on, covering made of plastic and secured over the airbag flap, wherein the covering has at least one target break line at the edge of the airbag flap in order to enable the unfolding of the airbag cushion, and wherein the airbag flap is connected via a joining point to a flap support wall in a moulded manner, which is in contact with the inner side of the chute channel wall in a secured manner, wherein the inner-side end of the flap support wall is bent outwards with a V-shaped or U-shaped cross-section, and with these hook-shaped bent region, same is inserted in the plastic material of the chute channel wall or engages under the lower end of the chute channel wall.

## Claims

### Claim 1

An airbag assembly comprising;
a launch pocket defined by walls made of plastic and delimiting an airbag hole;
an outer flap closing the hole;
an airbag in the pocket;
a cover element made of plastic, secured over the outer flap, and having at least one target break line forming the hole at an edge of the outer flap in order to enable unfolding of the airbag cushion and deployment through the hole;
an inner flap in secure contact with an inner face of one of the launch pocket walls and having an inner end; and
a hinge element unitarily joining the outer flap to the inner flap, the inner end of the inner flap being bent outward with a V-shaped cross section to form a cross-sectionally hook-shaped region that is embedded in the plastic of the one launch pocket wall without penetrating through the one launch pocket wall.

### Claim 2 (depends on 1)

The airbag assembly according to claim 1, wherein the inner end of a bent region of the inner flap is bent again with a V-shaped or U-shaped cross section and thus the inner end of the inner flap has a Z-shaped cross section.

### Claim 3 (depends on 2)

The airbag assembly according to claim 2, wherein the inner end of the inner flap has a material reservoir in the form of a fold or corrugation from which the bent region is bent away.

### Claim 4 (depends on 1)

The airbag assembly according to claim 1, wherein the outer flap and the inner flap are made from a composite material having at least one layer of plastic strips or fibers made from thermoplastic polypropylene or polyester and at least one plastic layer melted thereon.

### Claim 5 (depends on 4)

The airbag assembly according to claim 4, wherein the plastic strips or fibers form a fabric.
