Claim 14:
15. A method of manufacturing a helmet, the method comprising:
manufacturing a pad; and
mounting the assembled pad to the helmet,
wherein manufacturing the pad comprises:
arranging a first layer of material to cover a first side of a support member; and
arranging a second layer of material to cover the first layer of material, such that the first layer of material is between the second layer of material and the support member; wherein
a low friction interface is present between the first layer of material and the second layer of material to enable sliding of the first layer of material relative to the second layer of material during an impact to the helmet;
each layer of material is formed from at least one of a textile, a cloth, and a fabric, with a material forming each of the first and second layers of material having a grain defined by the orientation and/or the texture of the fibers forming the layer of material; and
the low friction interface is formed by the first layer of material and the second layer of material being arranged such that the grains of the first layer of material and the second layer of material are perpendicular.
