Abstract

An actuating device for a safety arrangement in a vehicle has a pneumatic muscle as drive and a pyrotechnical gas generator for feeding the pneumatic muscle.

Claims

1. An actuating device for a safety means in a vehicle, said actuating device comprising a pneumatic muscle as drive and a pyrotechnical gas generator for feeding said pneumatic muscle.

2. An assembly consisting of a safety means and an actuating device comprising a pneumatic muscle as drive and a pyrotechnical gas generator for feeding said pneumatic muscle, said safety means including a vehicle occupant restraint system with a housing and a covering flap which can be opened by said actuating device.

3. An assembly consisting of a safety means and an actuating device comprising a pneumatic muscle as drive and a pyrotechnical gas generator for feeding said pneumatic muscle, said safety means including a tensioning belt for fastening a cargo on a loading area of a vehicle and a tensioning device to be actuated by said actuating device for tensioning said tensioning belt.

4. An assembly consisting of a safety means and an actuating device comprising a pneumatic muscle as drive and a pyrotechnical gas generator for feeding said pneumatic muscle, said safety means including a retaining net which is arranged between a loading space of a vehicle and a passenger compartment, said retaining net being adapted to be spread out by said actuating device, in order to separate said loading space from said passenger compartment.

5. An assembly consisting of a safety means and an actuating device comprising a pneumatic muscle as drive and a pyrotechnical gas generator for feeding said pneumatic muscle, said safety means including a safety belt, which in a fastened condition is attached to three points of attachment in a vehicle, said actuating means engaging two of said points of attachment, in order to tension said safety belt in a case of restraint.

6. The assembly according to claim 5, wherein said safety means is arranged in a region of a front, upper edge of a sitting surface of a vehicle seat.

7. An assembly consisting of a safety means and an actuating device comprising a pneumatic muscle as drive and a pyrotechnical gas generator for feeding said pneumatic muscle, said safety means including a foot protection device for protecting the feet of a vehicle occupant, comprising a foot rest which is coupled with said actuating device.

8. An assembly consisting of a safety means and an actuating device comprising a pneumatic muscle as drive and a pyrotechnical gas generator for feeding said pneumatic muscle, said safety means including a raisable engine hood which can be transferred from an initial position into a raised position by means of said actuating device.

9. An assembly consisting of a safety means and an actuating device comprising a pneumatic muscle as drive and a pyrotechnical gas generator for feeding said pneumatic muscle, said safety means being a bumper which can be transferred from an initial position into an extended position by means of said actuating device.
