摘要

Device used in the protection of a vehicle occupant comprises an operatable vehicle occupant protection unit, and a microelectromechanical system unit (MEMS unit) which is stimulated into operating the protection unit. Independent claims are also included for alternative devices. Preferred Features: The MEMS unit is an excitable current source. The protection unit is an inflatable unit. The device contains elements leading the current from the MEMS unit into the inflatable unit to inflate the inflatable unit.
