The present invention relates to an impactproof head protection device. The device comprises of an outer shell, a flexible ring shaped elastomeric seal, an impact reduction layer and a base helmet. The impact reduction layer further comprises of an elastic net, on to which a plurality of impact reduction sub-assemblies are embedded. When the outer shell is subjected to an impact, the impact is conveyed to the impact reduction layer. The impact reduction sub-assemblies absorb the impact, and dissipate the same in the form of rotational motion of the microgears. The microgears stop rotating once all the absorbed energy is dissipated, and all the components of the impact reduction sub-assemblies once again revert to their original position on the elastic net.
