In this case the mating member (20) co-operates with the energyabsorbing member (10) in such a way that, if a critical shock force applied to the energy-absorbing device (100) is exceeded, the mating member (20) and the energy-absorbing member (10) move relative to one another, towards one another, while at the same time absorbing at least some of the shock energy which is applied to the energy-absorbing device (100). To enable the overall energy which can be dissipated by the energy-absorbing device (100) to be increased in a way which is easy to implement, provision is made in accordance with the invention for the energy-absorbing member (10) to have at least one energy-absorbing region (11) made of fibrous composite material which, in the course of the movement of the mating member (20) relative to the energyabsorbing member (10), is at least partly reduced to fibres non-ductilely.MEISSNER, BOLTE 2 /3 M/SBK-108-EP N a, N Cr N o a N N.) 0 N) -A Ct 0 )Cn 0 -A N Co -A N)C~) CA) -A 0
