ENERGY ABSORBING DEVICE, MOTOR VEHICLE BODY AND METHOD FOR MANUFACTURING THEREOF

Abstract:

An energy absorbing device is designed to increase the amount of absorbed energy and control the deformation of the device in case of an impact. The energy absorbing device consists in a hollow longitudinal member extending along a first longitudinal axis and a longitudinal guide extending along a second longitudinal axis, arranged within the longitudinal member and suitable for guiding the deformation of the longitudinal member in case of an impact. The length ratio between the longitudinal guide and the member is comprised between the values of 1/5 and 3/5.
