Abstract
The invention relates to a device for absorbing impact energy and more particularly to a device to be mounted to a conventional guard rail structure. The device consists of a skein of yarn of undrawn synthetic polymer and preferably nylon 6. The yarn is passed through the holes of a plate which, in turn, is mounted in a gap of a conventional guard rail structure. The weight of the skein is related to the amount of impact energy to be absorbed.
