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.
Claims3
A device for absorbing impact energy, comprising a water filled seal tight box, a plate secured to each end of said box having spaced holes therethrough, yarn of undrawn nylon 6 contained in said box and having a moisture content higher than two percent which is maintained at that level by the water in said box and which is wound in the form of a skein across said box by having said yarn pass through said holes in said plates, and wherein said yarn absorbs energy upon impact, and spaced guard rail structures between which and to which said box, plate and impact absorbing yarn are secured.
