  • Description
头盔是用来保护头部的护具。是军人训练、作战时戴的帽子,是人们交通中不可或缺的工具。它多呈半圆形,主要由外壳、衬里和悬挂装置三部分组成。外壳分别用特种钢、玻璃钢、增强塑料、皮革、尼龙等材料制作,以抵御弹头、弹片和其他打击物对头部的伤害。中国古代称为胄、首铠、兜鍪或头鍪。
 
现代头盔主要由盔壳、衬里和悬挂系统等构成。由于从事各种活动使用要求不同,头盔的结构和式样很多。
通常,头盔的壳体都由强度较高的材料制成,如金属、工程塑料、凯芙拉纤维等等,通过它的变形来吸收大部分冲击力;衬里材料具有吸汗、保暖、减震的功能,头盔则往往还具有进一步减缓冲击力、防止壳体碎片伤及头部的功能;悬挂系统则是介于壳体与内衬之间的部分,通常可以调节,以适应不同的佩戴者头型的差别。
