Abstract

A cover element (10) for an airbag unit having a stationary section, a first flap (14), and a second flap (20), wherein the first flap (14) is connected to the stationary section by at least one first hinge (31), and the second flap (20) by at least one second hinge (32). The two flaps (14, 20) are connected to each other by a tear connection (35). The first flap (14) has an outer area (16) and an emblem area (18), which protrude at least partially from the outer area (16) and extend into the second flap (20). In order that the emblem area (18) is not in the way of the expanding airbag even if the emblem area (18) is relatively large, the emblem area (18) is connected to the outer area (16) of the first flap (14) by a third hinge (33), so that the emblem area (18) can swing against the outer area (16) when the first flap (14) is open.

First claim

The invention claimed is:

1. A cover element for an airbag unit, the cover element comprising a stationary section, a first flap and a second flap, wherein the first flap is connected to the stationary section by at least one first hinge, and the second flap is connected to the stationary section by at least one second hinge,
wherein, in an initial state in which the airbag unit is undeployed, the first and the second flaps are connected to each other by a first tear-away connection,
wherein the first flap has a first outer area and an emblem area, which protrudes at least partially from the outer area and extends into the second flap and is connected to the second flap via the first tear-away connection,
wherein the emblem area is connected to the outer area of the first flap by a third hinge extending non-parallel to the first hinge and by a second tear-away connection, so that the emblem area can swing against the outer area when the first flap is open upon a deployment of the airbag unit.

2. The cover element according to claim 1 , further comprising an emblem disposed on the emblem area.

3. The cover element according to claim 1 , wherein the stationary section includes a lateral wall.

4. A cover element according to claim 1 , wherein only the first and the second flaps are provided.

5. A cover element according to claim 4 , wherein the first and second flaps form an entire top of the cover element.

6. A cover element according to claim 1 , further comprising a third flap in addition to the first and the second flaps.

7. An airbag module having a housing with an outlet opening, a gas generator held on the housing, an airbag folded into the housing, and a cover element in accordance with claim 1 .
