Safety system for use in a vehicle
First Claim
1. A safety system for use in a vehicle comprising a fuel cell system, a fuel supply means, an electrical energy source, said fuel cell system having at least one component connectable to said electrical energy source, a plurality of sensors associated with said fuel cell system and adapted to deliver safety relevant signals and a safety control for said fuel cell system, said sensors being connected to said safety control, said fuel cell system having at least one device for switching off said fuel supply means and also at least one device which can be actuated by said safety control for separating said at least one component from said electrical energy source, an airbag system having at least one airbag, at least one gas generator associated with said airbag for the inflation thereof, an airbag control controlling said gas generator, a plurality of sensors, a circuit connecting said sensors to said airbag control and adapted to deliver safety relevant signals for the triggering of said airbag, said safety control of said fuel cell system being one of connected to said airbag control and functionally replaced by said airbag control.

Abstract
A safety system for use in a vehicle having a fuel cell system with a fuel supply means and an electrical energy source, wherein a plurality of sensors are associated with the fuel cell system and deliver safety relevant signals, these sensors are connected to a safety control and the fuel cell system has at least one device for switching off the fuel supply device and also at least one device which can be actuated by the safety control for separating at least one component of the fuel cell system from the electrical energy source, is characterized in that the safety system stands in association with an airbag system having at least one airbag with at least one gas generator associated with the airbag for the inflation of the airbag, preferably also with at least one safety belt with a belt tensioner, with an airbag control controlling the gas generator and optionally also the belt tensioner and also a plurality of sensors which are connected via a circuit to the airbag control and deliver safety relevant signals for the triggering of the airbag and/or of the belt tensioner; and in that the safety control of the fuel cell system is either connected to the airbag control or the airbag control functionally replaces the safety control of the fuel cell system.
