Abstract

A neck brace (10) is disclosed which comprises two sections (12, 14) which are releasably connected to one another along a split line (18). The ring has upwardly facing surfaces (30, 76.1, 20.2) which limit tilting movement of a helmeted head in all directions. The brace further has a column (68, 70) which extends downwardly from the ring for transferring loads to the wearer'"'"'s back on each side of the spine.
