  • On the airbag module and/or on a Additional support surfaces are provided on the steering wheel cover and/or on the open steering wheel rim and/or on a steering column to support the deployed and inflated driver airbag.
  • US 7,669,890 B2 discloses a steering wheel with an open steering wheel rim and an airbag module with a driver airbag arranged in the impact pot of the steering wheel.
  • the airbag module comprises another airbag which is unfolded and inflated to withstand pressure exerted by the driver on the driver airbag and to support the driver airbag in its inflated position of use.
  • a support element can be arranged on the impact pot which is transferred to its position of use in the event of a serious crash, in which the support element supports the driver airbag in its inflated position of use.
  • the steering wheel comprises a support unit which, in the event of a crash, can be moved from a stowed position to an operating position facing the driver, in which the support unit supports a rear surface of the unfolded and inflated driver airbag in the open area of the steering wheel rim.

  • an instrument panel for a vehicle with the features of patent claim 1.
  • Advantageous embodiments with expedient further developments of the invention are specified in the dependent patent claims.
  • a support arrangement is arranged on the instrument panel in the area of the steering wheel, which has at least one support geometry and a setting device.
  • the setting device is designed to set up and hold the at least one support geometry from a storage position to a use position in the event of a crash.
  • the at least one support geometry supports the inflated driver airbag of the airbag arrangement in the use position.
  • the support geometry can be set up actively or passively using various technical solutions. Since the support geometry is only set up in the event of a crash, a line of sight to a display device arranged in front between the steering wheel and a windshield is advantageously not interrupted during ferry operation.
  • the at least one support geometry can support at least one head region of the inflated driver airbag in the use position, which protrudes over a steering wheel rim and creates a restraining effect for the driver's head.
  • This means that the support of the inflated driver airbag can also be ensured if the steering wheel rim is interrupted in the upper region in a basic position of the steering wheel.

  • the driver airbag can be arranged folded up in a resting state in an impact pot of the steering wheel and can be converted into its inflated operating state in the event of a crash.
  • the steering wheel can have a moving steering column which, in the event of a crash, moves the steering wheel as far as it will go towards the instrument panel due to the force exerted by the driver on the inflated driver airbag. This can save energy. In addition, the forces acting on the driver in the event of a crash can be reduced.
  • the setting device can be designed as a passive setting device with a setting mechanism which can be activated in the event of a crash by the movement of the running steering column.
  • the setting mechanism can, for example, comprise two guide elements, each of which can have an inclined guide surface.
  • a first guide element can be connected to an actuating lever for the at least one support geometry, and a second guide element can be coupled to the running steering column.
