摘要: An adjustable-force energy absorbing device includes first and second support members connected for sliding movement in a direction parallel with the steering shaft axis of vehicle, member being secured to vehicle chassis, outer tube mechanism. Upon impact, is displaced from its normal position spaced one end toward adjacent end. This displacement resisted by at least U-shaped element, number and/or degree operability elements controlled impact-responsive pyrotechnic device.
