Description
Shellproof protective helmet technical field is imitated entirely
The present invention relates to the civilian or anti-riot shellproof protective helmet of army and police.Background technology
Existing protective helmet is made up of helmet shell, helmet top suspension, chin belt and its connector.Wherein, the function of helmet shell be prevent bullet or fragment from penetrating, anticollision, rainwater-proof etc., effectively protection wearer's head safety；Helmet shell may also provide installation protective face mask and other protection, measurement, communication device；The selection of material of helmet shell according to specific needs depending on; key is to protect the head safety of user; and should accomplish that proportion is small, easy processing; it is generally divided into metal, nonmetallic, compound three kinds of helmet; structure carries out moulding by head shape; using peak class elliposoidal structure, it is important to accomplish that protection effect is good, it is set to be difficult to be punctured by bullet etc..
