<p>The purpose of the present invention is to provide a shell laminated structure realizing a further light weight formation of a helmet while improvement for shock absorbing characteristic is assured. There is provided a laminated structure in which either the net-like member 2 or the sheet-like member having many holes is placed at an entire region of the shell 1 having a reinforcing base material or between the laminated layers at a part of the shell in such a manner that the sheet-like member is extended along the layer to which its front and rear surfaces are faced, bitten into the layer and fixed. With such an arrangement as above, a further light weight formation of the shell is realized while a high safety characteristics of the helmet is assured. <IMAGE></p> |
