The safety helmet includes a first section, a second section and an extension section defined between the first and second sections. The first section is sprayed with a figure. A decorative section or a figure layers is adhered to the second section. After a periphery of the decorative section or figure layer partially passes over an edge of the second section, the periphery of the decorative section or figure layer enters the extension section. The first and second sections together form a helmet subassembly. The helmet subassembly is placed in a mold and integrally bonded with a buffer material or foam material filler to form a helmet assembly. ## Claims ### Claim 1 A safety helmet structure comprising: a first section having an outer surface and an inner surface;
