Abstract
A neck protection apparatus features a support member arranged to couple to a pair of shoulder pads, a brace arm connected to the support member by a pivotal coupling to allow pivoting of the brace arm toward and away from a plane of the shoulder pads, a flexible elongate member for coupling between the brace arm and a helmet, and stop features for limiting a pivotal motion of the brace arm relative to the support member to a predetermined angular range. Maximum extent of the angular brace arm in opposing directions limits neck movement by using the arm to block rearward movement of the helmet and using tension in the flexible elongate member to restrain forward movement of the helmet, while the flexible elongate member accommodates freedom of head movement between these extents.
