Abstract:
A method for optimising an energy-absorbing strap includes the steps of: (1) producing a single metal sheet, including a first connecting portion, for connecting to one of a support bracket and a fixed part of a vehicle, and a second connecting portion, for connecting to the other of the support bracket and the fixed part of the vehicle; and (2) producing a weakening in the single metal sheet to separate the first connecting portion from a tearable portion; bending a portion of the single metal sheet to produce a bent portion that interconnects the second connecting portion and the tearable portion, the second portion being bent back around in relation to the tearable portion; wherein the steps are selected to produce a desired energy-absorbance profile.
