  • Vehicle steering column including a pyrotechnic charge
    Patent number: 6578872
    Abstract: A system for variable absorption of energy in the direction of the axis of an automobile vehicle steering column includes a steering shaft mounted in a body-tube connected to a mobile support member connected to a fixed support member fastened to the chassis of the vehicle and immobilized thereon up to a particular value. A coil is disposed on each side of the steering shaft and is connected to each of the fixed and mobile support members by a respective connecting pin A pyrotechnic displacement system operates selectively on a mobile retaining rod of each coil to modulate the absorption of energy in the event of an impact.

  • System employing pyrotechnic charges for variable absorption of energy from automobile vehicle steering
    Publication number: 20020020999
    Abstract: A system for variable absorption of energy in the direction of the axis of an automobile vehicle steering column includes a steering shaft (1) mounted in a body-tube (2) connected to a mobile support member (9) connected to a fixed support member (8) fastened to the chassis of the vehicle and immobilized thereon up to a particular value. A coil (25) is disposed on each side of the steering shaft (1) and is connected to each of the fixed and mobile support members by a respective connecting pin (11, 12). A pyrotechnic displacement system (41, 42) operates selectively on a mobile retaining rod (32) of each coil (25) to modulate the absorption of energy in the event of an impact.
