A neck brace (10) is provided, which has an impact surface (30) which that can limit movement of a helmet by contacting an underside of the helmet, bearing surfaces (44,72,88) configured for bearing on the body of a wearer, and a structure (24,66,94,100) between the impact surface (30) and the bearing surfaces (44,72,88), that can transfer impact loads of the helmet on the impact surface (30), to the wearer's body. Parts (92,98) of the neck brace (10) that defines part of the impact surface (30) are displaceable towards the wearer s body and the structure (94,100) is configured to permit the displacement at rates slower than a predetermined rate, but to resist displacement if the rate exceeds the predetermined rate. The displacement of the parts (92,98) allow the wearer to move the helmet to positions not otherwise permitted by the impact surface (30), but the resistance to displacement ensures that impact loads can still be transferred from the helmet to the body, during impacts. |
