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.
A coating for protecting a surface of an inanimate object from a shock, comprising:
The coating of claim 5, wherein the lines of least resistance of the second layer are staggered with respect to the lines of least resistance of the first layer so that an area of impact on the second layer is enlarged to a greater area of impact on the crushing material by the first layer.
The coating of claim 6, wherein the rigid material is selected from the group consisting of cement, concrete, metals, steel, glass, ceramic materials, plastic materials, composite materials, brick and stoneware, the first and second layers being of either the same or different rigid material.
A shock damper coating for a surface to be protected, comprising:
A coating for protecting a surface from the impact of a shock, comprising:
