- the ring is advantageously arranged on the outside of the additional weight and may form the shoulder, which projects radially outward, to serve as an undercut or positive locking element for the fastening elements.
- the holder may be formed as a vibration absorber for an airbag, so that the device may be formed together with the airbag as an airbag module in which the gas generator and optionally the additional weight are elastically mounted. Due to the mass of the holder together with the mass of the gas generator, the air bag and optionally the additional weight, the vibrations can be effectively eradicated on the steering wheel.
- additional weight predetermined breaking lines may be formed, which surround areas with defined weights, so that, starting from a basic additional weight by removing defined weights, the desired additional weight can be adjusted. For this purpose, those materials within the predetermined breaking lines are removed, which correspond to the weight to be removed.
