Abstract:
A helmet liner adapted to be conformed to an inner surface of a helmet to cushion in use the rear of a wearers head from the helmet is described. The liner comprises a plurality of elongate grooves comprising at least one longitudinal groove configured to extend in use along a longitudinal direction between the nape of a wearers neck and the crown of the wearers head, and at least one lateral groove adapted to extend in use at least partially around the head of the wearer in a lateral direction between the wearers ears. The at least one longitudinal groove is deeper than the at least one lateral groove.
Abstract:
There is provided a pad (17) for attachment to a textile by heating, the pad comprising a body (3) comprising an elastic, energy absorbent material, which exhibits a resistive load under deformation which increases with the rate of deformation, the body having a first surface (7) and an opposing second surface (21), and a layer of heat sensitive adhesive (5) at least partially covering the first surface of the body and being bonded to the first surface, at least at the periphery thereof, so that the pad may be attached to a textile by heating.
Abstract:
An impact resistant textile-supported garment, or component thereof, comprises a fabric layer, and (i) at least five non-interconnected impact resistant polyurethane segments upon an outer surface of the fabric layer, wherein at least two of the non-interconnected impact resistant polyurethane segments has a depth of at least 3 mm, preferably at least 4 mm, and wherein at least five of the plurality of non-interconnected segments have dimensions smaller than 1.75 cm × 1 cm × 1 cm; or (ii) at least one non-interconnected impact resistant polyurethane segment, wherein the at least one segment has a depth of at least 3mm at its deepest part, and wherein the at least one segment is a hollow segment comprising one or more regions defined by an outer polyurethane perimeter, surrounding a region of fabric that is not covered by polyurethane.
Abstract:
A shield system for protecting a curved object is described. The system comprises at least one flexible pad. The at least one flexible pad comprises a spacing ridge (7) projecting at an angle from a first major surface3of the pad for providing a spacing between the first major surface and a support ridge9projecting from the first major surface and extending transverse to the spacing ridge. The support ridge comprises a flexure region (11) adapted to unbend in the event that the pad is curved about an axis aligned with the spacing ridge to inhibit strain in the support ridge from causing deflection of the spacing ridge. Apparatus of the disclosure, such as shield systems, for example cases for protecting objects, and objects themselves comprising ridges as defined herein may be provided with or without shield shells and may be provided with or without pads.
