摘要

It includes: a protective helmet, a helmet shell, a built-in fixation, a device for connecting the head, a support cage 42, a head belt (44),And a neck chain. The internal fixing pillar is composed of three bracket arms (54, 55, 56), which form a spacing from the bracket (42) of the temple to the side, or back and down, in the rear area of the head, as a means of fixing in the hull. In this way, the fixed sub body is kept at a distance from the hull throughout its outer ring. A free spaceIt exists in all internal fixation sub levels, making it possible to decouple the helmet from the internal fixation sub level relatively. The free ends (54, 55, 56) of the support arms are respectively irrevocably connected with the helmet shell. The releasable fixed bracket (56) is on the back and back, including the rear mounting point of the hull shell locked in its longitudinal direction, and in addition, a suspended or effective bracket exceeds the lock in its transverse direction and an additional mounting point Inside of helmet shell
