Abstract
Abstract A device senses movement of the front part of an airbag during deployment with a sensing element that is extended during inflation of the airbag and delivers a measured value for the movement of the airbag. Electrical connections are mechanically separated in a time sequence during the sensing of movement, the successive separation processes being detectable electrically and/or electronically.
