PURPOSE: To provide an energy converter improved so as to generate a roughly constant load or gradually increasing load in a desired mode in a vehicle restraining system, decrease a load peak more in the restraining system and so as to make it almost nil. CONSTITUTION: A tubular converter body 10 formed of a plastically-deformable material is provided, in which piston elements 14, 16 are disposed as a deformation means to which a tension cable 12 is connected. The deformation means is disposed with a ball 18 serving as a rolling element for the deformation member on only one side, and is slidably-supported inside the converter body 10 on the opposite side in its radial direction. The ball 18 is supported on a ramp face 20 of piston elements 14, 16 respectively on the side distant from the wall of the converter body 10, and engages with the wall of the converter body 10 along with the displacement of the deformation means within the converter body 10 in a predetermined direction F2 and plastically-deforms the wall along with further displacement. |
