A bicycle helmet that allows ventilation to a cyclist head. The helmet comprises a hard internal shell, a hard external shell, and a shock absorbing foam insert located between the internal and external shells. The helmet consists of a generally open concave structure having a number of fore and aft extending structural arms, transversely spaced from one another and merging with an annular bottom edge rim at both their fore and aft ends. Each structural arm forms a U-shape in cross-section, for reinforcing the helmet structure. The shock absorbing foam of the insert engages with the grooves formed by these cross-sectionally U-shape structural arms. Air ventilation passages are formed in between each pair of successive U arms, extending through corresponding openings in the shock absorbing insert and through the open mouth formed by the annular internal shell. The radius of curvature of the structural arms is greater than that of the shock absorbing insert.
A generally open concave bicycle helmet comprising a hard external shell, a shock absorbing insert located radially inwardly of said external shell;
A bicycle helmet comprising a generally open concave shock absorbing insert, said insert defining a top exposed surface and an internal face in communication with one another via air circulation passageways extending radially through said insert, a number of rigid reinforcing cross-sectionally U-shape hoops extending across corresponding strip portions of said insert exposed surface, each of said U-shape hoops defining two opposite side legs and a groove between said side legs, said hoops side legs being embedded radially inwardly into corresponding said insert strip portions;
