Abstract
A helmet includes a shell, a brim, ridges, and multiple flexible structures. The shell is shaped to receive a user's head. The brim covers the user's forehead and areas above the temples and ears and protrudes from the outer surface of the shell. The ridges are located along the back and top of the helmet and also protrude from the outer surface of the shell. The flexible structures, which are made of a material that is more flexible than the shell, the brim, and the ridges, are positioned in separation gaps between the shell and the brim and ridges. The shell, brim, ridges, and flexible structures are fused together as a single unibody. When the helmet is subjected to an impact on the brim or the ridges, the corresponding flexible structure deforms so that the brim or ridge moves relative to the shell. The deformation of the flexible structure attenuates the force of the impact, which improves the helmet's ability to protect the user from impacts.
