Abstract
An energy-absorbing device disposed between two elements which are movable apart from each other in response to an externally applied force. The device has a wire coil winding having a plurality of turns at one end and a rectilinear length portion at another end extending away from a turn of the coil winding. One of the two elements has a support axis about which the coil winding turns are would axially thereof. A second of the two elements has an end of the rectilinear length portion of the wire secured thereto. The turns of the coil winding are deformable and unwind about the axis to absorb energy of a force applied in a direction parallel to the rectilinear relatively separating apart the two elements. The energy device is uable on automobile vehicle steering columns for absorbing impact forces.
