Document Type and Number:
WIPO Patent Application WO2004030987
Kind Code:
A3
Abstract:
A single sided crash attenuation cushion system (14) having an impact head and a three stage energy absorption mechanism. Each stage of the energy absorption mechanism provides an increasing level of kinetic energy dissipation as the cushion system collapses. The third stage of the absorption mechanism includes an additional deformable compressible tube between the fixed-object hazard and the thin walled tubes.
