- Sensor data is a gas generator unit, which may also be part of the airbag module or housed in a remote area of the motor vehicle and a
- Supply line may be connected to the airbag activated.
- the deployment gas provided by the inflator flows into the airbag and causes the inflator
- Airbag cover ruptures.
- the airbag passes through the torn-open airbag cover and inflates between the motor vehicle steering wheel, the steering column and the vehicle occupant.
- Sollrisslinien are provided in the airbag cover, for example, by material reduction or embrittlement. This makes it possible for the airbag cover to tear along certain lines, so that a more or less defined and reproducible deployment of the airbag can be effected.
- the airbag modules that are equipped with such an emblem are suitable only for a vehicle model or a manufacturer, interchangeability of the airbag module, for example between different models or within a group, is not given.
- WO 2005/032893 A1 describes a motor vehicle steering wheel with an airbag module which has an airbag container with an inflatable airbag and a tear-open cover.
- an active display device is arranged, which is formed on the cover of the airbag container or forms this cover itself.
- the display device is designed as an OLED display and has predetermined breaking lines or predetermined breaking points, which cause the display device to break when the airbag is unfolded.
- Object of the present invention is to provide a motor vehicle steering wheel and an airbag module, which are versatile, meet high safety requirements and are well recyclable.
- the arrangement and attachment of the display device to only one flap ensures a defined assignment of the display device to a specific flap.
- the display device is preferably designed as an LCD, which is designed for example as a display in the TFT technology.
- the display device may also be designed as an OLED display and based on light-emitting diodes based on organic semiconductors. Other display designs are also possible and provided.
- a common difficulty in operating display devices is driving the display device. According to the invention, it is provided that cables or
- Supply lines are attached to the display device on exactly that flap or embedded only in that flap on which the display device is mounted.
- the airbag module with the airbag cover thus has integrated or fixedly attached supply lines for the provision of energy and information, wherein the supply lines are fixed only to the flap and along it, on which also the
- Display device is attached.
- a contact with external control devices can take place via a plug connection, which is closed during assembly of the airbag module in the motor vehicle steering wheel.
- the display device can either be firmly connected to the cable or the supply lines or coupled thereto via a plug connection.
- a development of the invention provides that the display device is assigned a control unit which activates the display device when opening a vehicle door and / or during operation of the vehicle. If, for example, the vehicle door is unlocked or opened, the display device is automatically activated via the control unit, so that the vehicle user finds an activated display device when boarding.
- the display mode of the display device remains during operation of the motor vehicle, so that the vehicle user during the entire operating life of the motor vehicle, an active display device can be provided.
- an emblem can be displayed, which applies to the relevant motor vehicle model.
- a control unit By controlling the display device via a control unit, it is possible to provide different brightnesses as a function of the time of day or the lighting condition in the vehicle interior. It is also possible to make color adjustments easily, for example, to adapt the emblem to the selected vehicle equipment or the selected vehicle color. It is also possible to change the displayed colors without having to replace an emblem.
- the control unit may be configured such that the display device remains activated after the vehicle has been parked for a defined period of time in order to continue to display the emblem or the displayed information for a longer period of time.
- the display device still lights up after parking the vehicle or closing the vehicle door for a predetermined period of time.
- the vehicle emblem is preferably displayed in the display device, as a basic mode of representation.
- the display device is preferably fixed in a form-fitting manner to the airbag cover, so that it is possible to easily separate the display device from the flap after deployment of the airbag and to make it accessible for further processing or reuse. Due to the fact that the display device is attached only to a flap, it is ensured that damage to the display device does not occur solely by the tearing open of the airbag cover, so that it is possible to continue to use the display device. Also, the arrangement of the display device on only one flap of the tearing operation of the airbag cover is not or only minimally affected.
- the invention also relates to an airbag module which is designed as described above.
- airbag modules can be installed in steering wheels of motor vehicles, but alternative installation sites are possible and provided. Therefore, the features and advantages of an airbag module described above in connection with installation in a steering wheel are also generally applicable to suitably designed or equipped airbag modules, regardless of their installation location.
