Safety mechanism for crash helmets with chin straps - is safety collar strap with loops holding chin strap secure during accidents

摘要

The crash helmet is held in place by a flexible safety strap (3) which is curved like a collar and has a centre neck section (4) whose width corresponds approximately to the height of the nape. The two tapering side sections (5) each end in a loop (6). Once the helmet is put on the two parts of the open chin strap are passed through the loops and closed in the normal way. In the event of accident the safety collar strap prevents the helmet from flying off. The safety strap can have a length adjustment mechanism for adapting to different sized heads.
