Abstract: A protective device is provided for protecting the back of a wearer against injury. The device includes an array of support elements that extend along the wearer's back adjacent his spine and is held in position on his back by attachment means, which can include a neck brace attached to the upper end of array, a chest strap, a waist strap and/or webbing that are spaced apart axially along the array. The support elements are attached to each other in such a way that they can move relative to each other to allow free, but limited bending, extension and contraction of the array, but the connection means between the elements is configured to prevent further movement between them once a predetermined limited movement has taken place, so that the array becomes practically rigid and can bear further loading that may otherwise have been born by the spine.

Abstract: A neck brace comprising an impact surface which that can limit movement of a helmet by contacting an underside of the helmet. The neck brace further comprises at least one bearing surface configured for bearing on the body of a wearer, and a structure extending between the impact surface and the bearing surfaces configured to transfer impact loads of the helmet on the impact surface to the wearer's body. A part of the impact surface is displaceable towards the wearer's body and the structure is configured to permit the displacement at rates slower than a predetermined rate, as well as to resist displacement if the rate exceeds the predetermined rate.

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.

Abstract: Neck brace that inhibits excessive neck movement during impact, yet allows for a high degree of movement of the wearer's head during normal operation of the neck brace. May include impact surface(s) that limits movement of a helmet by contacting an underside of the helmet; bearing surface(s) configured for bearing on wearer; a structure between impact surface and bearing surface, sufficiently resilient to transfer impact loads of the helmet to the impact surface, to the wearer's body; wherein the impact surface is displaceable towards an adjacent part of the bearing surface and wherein the structure is configured to permit the displacement at rates slower than a predetermined rate of displacement and to resist the displacement if the rate of displacement exceeds the predetermined rate. May include a pivotal joint between the displaceable part and remainder of neck brace and impact brake element(s).
