Abstract
A safety device for a motor vehicle includes a multi-chamber airbag, which is inflatable by at least one gas generator activatable when a vehicle is impacted. The airbag includes at least one feeler, or tactile, airbag, which may be quickly inflated using only a small quantity of energy and which is provided with a touch, or tactile, function. The feeler airbag may be inflated and introduced into an inflation area of at least one second airbag chamber and identifies, by touch, an obstacle in the inflation area, such as an out-of-position occupant. A touch recognition device is connected to the feeler airbag and emits a control signal, which is utilized at least during the inflation phase. The gas generator includes a control device for the inflowing amount of gas, the control device being connected to the touch recognition device and preventing, or at least reducing, a further inflation function of the gas generator when receiving the control signal.
