Abstract
The damper coating for shocks produced by a collision, or impacts produced by a shockwave, contains at least one layer of a crushing material (2) intended to cover a surface to be protected, the external layer of the crushing material (2) being, according to the present invention, covered by a skin (4) capable of providing a widening of the area affected by the shock or impact. The skin (4) contains, in particular, several layers (5.sub.1 ; 5.sub.2 ; 5.sub.3) of scales (6.sub.1 ; 6.sub.2 ; 6.sub.3), the scales of one layer being offset in staggered rows with respect to the scales of the following layer and being separated from the neighbouring scales of the same layer or capable of being separated from the latter on the application of the shock or impact. The structure of this damper coating is designed to dampen the impact under a reduced thickness.
