Abstract

In a gas generator for an airbag of a vehicle, a chamber is provided around a cylindrical pressure reservoir filled with gas-releasing materials. The chamber contains a filter and is traversed over its entire length by a gas stream produced from the gas-releasing materials along a cylindrical outer surface. Such a gas generator is especially suitable for an airbag intended to prevent primarily only the impacting of the driver's head against the steering column while the other protective functions, which are otherwise also to be carried out by an airbag in a vehcle as the sole protective device, are taken over by a safety belt.
