Pyrotechnic drive, in particular for vehicle occupant restraint systems |
摘要 |
A pyrotechnic drive, in particular a linear drive for vehicle occupant restraint systems comprises a cylinder having a cylinder wall and a working space, a piston which together with the cylinder wall delimits the working space, and several pyrotechnic propellant charges producing gas. The gas reaches the working space and thereby sets the piston in motion relative to the cylinder. The propellant charges are ignited staggered in time relative to each other and comprise a first propellant charge integrated in the piston and a second propellant charge connected with the cylinder wall.
