Problems solved by technology

Accordingly, the safety helmet 1 causes discomfort to the user and is harmful in terms of safety
In addition, when the user drives the motorcycle at a high speed, although air can flow into the interior of the safety helmet 1 through the vent hole 31, the vent hole 31 causes the user to be exposed to very loud wind noise, which interferes with the user's concentration on driving.
As a result, accidents can happen

Embodiment Construction

[0017] refer to figure 2 , in manufacturing a safety helmet according to an embodiment of the present invention, a liner 110 defining an inner space of a user's head and having an opening on a lower portion thereof is molded. Next, the exterior of the liner 110 is covered with a reinforced fiber sheet 113 .

[0018] Since it is preferable that the liner 110 has a thickness of 1-2mm, the liner 110 is made of thermoplastic resin by molding. Such a molding method is widely known to those of ordinary skill, and description thereof is omitted. The resin used for the liner 110 may be such as polyethylene resin, polystyrene resin, polybutylene terephthalate resin, polyvinyl chloride (PVC) resin, polymethyl methacrylate (PMMA) resin, acrylonitrile - A resin of butadiene-styrene (ABS) resin, polycarbonate resin or nylon resin.

[0019] The reinforced fiber board 113 is formed using a woven or non-woven fabric made of high-strength fibers and high-strength elastic fibers. The reinf...

Abstract

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

Description

technical field [0001] The present invention relates to a method of manufacturing a safety helmet, such as a motorcycle helmet or a sports helmet, and a safety helmet manufactured using the method, in particular to a fiber-reinforced composite material comprising high-strength fibers, relatively strong elastic fibers and thermosetting resin The shell made of the material is easy to manufacture a safety helmet, and is an improved safety helmet with light weight, low cost, impact resistance, and good internal ventilation. Background technique [0002] Safety helmets are used to protect a person's head from injuries caused by sudden accidents that occur when people drive motorcycles or racing cars or work at construction sites or special work sites. figure 1 Is a cross section of an example of a conventional motorcycle safety helmet. [0003] refer to figure 1 , a conventional safety helmet 1 comprising a shell made of a fiber-reinforced composite material including high-stre...
