Abstract: Head and neck restraint apparatus for an occupant of a vehicle comprises a stiff yoke shaped to engage the upper torso and shoulders of the occupant. The yoke is generally U-shaped, with a base and upwardly extending limbs, and has a frontal portion shaped to extend over the chest of the occupant which corresponds to the base of the U. An intermediate portion of the yoke is shaped to fit over the shoulders of the occupant, and an upper portion of the yoke, corresponding to the upper ends of the limbs, extends beyond the intermediate portion to constrain movement of a helmet worn by the occupant. A set of first guides on the yoke are arranged to engage harness members of a safety harness worn by the occupant. Each guide is shaped to engage a respective harness strap or buckle and responds to longitudinal movement of the harness strap or buckle.

Abstract: A neck brace (10) comprises an impact surface (39,55) adjacent the neck of a wearer of the brace (10) that it is spaced from a helmet (42) and that is configured to limit movement of the helmet by contacting an underside (46) of the helmet, a bearing surface (15,35) bearing on the wearer's body; and a resilient structure (12) between the impact surface (39,55) and the bearing surface (15,35) for transferring impact loads from the helmet (42) on the impact surface, to the wearer's body via the bearing surface. The brace (10) further includes restraining means (58) that is attachable to the rear of the structure (12) with a releasable clip mechanism (66) and to the helmet (42) to inhibit movement of the helmet. The restraining means is in the form of a tether (58) that is attached to the helmet (42) at two spaced locations and that passes with clearance through an aperture in an anchor element (62,64), to allow the helmet (42) to be moved freely while the tether (58) slides through the aperture.
