The present disclosure relates to a cushion for use in a helmet comprising an outer shell for impact with an incoming force, the cushion disposed between the outer shell and a head when the helmet is worn, the cushion comprising: a sealed bladder comprising a flexible membrane; a pad housed within the bladder, said pad comprising a compressible member having interstices open to the exterior of the pad; and a liquid within the interior of the bladder; wherein said pad absorbs at least some of said liquid when uncompressed and expels said liquid when compressed; and wherein the volume of liquid within the bladder is sufficient to allow opposing surfaces of the bladder to be displaced in a shearing motion relative to each other when the cushion is compressed and subjected to shear forces, to decouple shear forces between said helmet and the head.
A body armor system comprising an outer impact-receiving layer and an at least one cushion interior to said layer for managing shear forces impacting the outer impact-receiving layer, said cushion comprising a sealed flexible bladder filled with a liquid and containing a compressible and resilient solid element therein, wherein the solid element is configured to permit the liquid to flow at least partially around the element.
A cushion for managing shear forces in a body armor, the cushion comprising a sealed flexible bladder filled with a liquid and containing a compressible and resilient solid element therein, wherein the solid element is detached from at least an upper or lower surface of the bladder to permit the liquid to flow at least partially around the element.
