Abstract

A device for protecting a vehicle occupant includes an airbag, a first sensor which detects the presence of an object or of the vehicle occupant in a danger area into which the airbag unfolds as it inflates, and a second sensor for measuring the unrolled belt length of a belt device which is assigned to a vehicle seat. An evaluator controls the inflation of the airbag as a function of the detection of the object or of the vehicle occupant in the danger area and as a function of the belt length. A method for controlling the inflation of an airbag is also provided.
