摘要
An improved lightweight, shock-resistant and tension-proof safety helmet manufactured at a low cost is provided. The safety helmet includes a shell, which is manufactured by molding a liner using a thermoplastic resin, covering the outside of the liner with a reinforced fiber sheet, preparing a mold, disposing the liner upside down on a concave molding side of the mold, injecting a thermosetting resin between the liner and the molding side, hardening the thermosetting resin, and detaching the hardened thermosetting resin from the mold; and a cushion pad attached to the inside of the liner. The safety helmet may include a guide surface referred to as a wind flap in order to guide external air into the safety helmet.
