Abstract

A method of controlling inflation of an airbag in a motor-vehicle accident protection device, includes activating a gas generator in response to a firing signal for inflating the airbag. A temperature and/or a pressure of the gas generator is measured and the inflation takes place in such a way that a desired pressure profile in the airbag is achieved.
