Abstract
A safety device for a motor vehicle includes an airbag configuration with a sensing airbag and a protective airbag. The sensing air bag is finger-shaped and has a small volume. A gas generator inflates the sensing airbag with a low power in the event of a vehicle impact. The inflated sensing airbag extends into an inflation zone of the protective airbag in order to sense any obstacle disposed therein. A touch-sensing device is connected to the front of the sensing airbag and provides a control signal when the sensing airbag encounters an obstacle. When the control device receives the control signal, the control device prevents or at least reduces the inflation of the protective airbag. When the control device does not receive the control signal, the protective airbag is inflated with full power.
