ENERGY-DISSIPATING ELEMENT AND SHOCK ABSORBER COMPRISING AN ENERGY-DISSIPATING ELEMENT

摘要

The invention relates to an energy-dissipating element (1) in the form of a hollow body extending in the longitudinal direction (L), wherein the energy-dissipating element (1) comprises a wall (2) forming the peripheral surface of the hollow body, and wherein the energy-dissipating element (1) is designed to respond upon the exceeding of a critical impact force applied to a front end of said energy-dissipating element (1) and to convert at least a portion of the impact energy ensuing from the transfer of the impact force through the energy-dissipating element (1) into the energy and heat of deformation by plastic deformation. With the objective that the remaining block length be as small as possible in the space available and that the energy-dissipating element (1) will thereby enable sufficiently high energy dissipation in the longitudinal direction (L) with a defined response of said energy-dissipating element (1) as well as with a predictable sequence of events during the absorbing of energy, the energy-dissipating element (1) according to the invention comprises at least one deformation element (3, 3.1 to 3.n) formed from a profile, a hollow profile in particular, and extending along the longitudinal axis (L) of the hollow body which forms the wall (2) of said energy-dissipating element (1).
