Abstract
Abstract A covering for objects that are exposed to impacts, such as road and bridge parapets, guiding curbs, motorcar bumpers, central reserve guard rails for expressways etc. The covering comprises a jacket of resilient material with a hollow space therein in which a damping material, preferably sand, is enclosed. The hollow space has a volume greater than the damping material, whereby the latter can expand when the covering is exposed to an impact.
