Abstract:
A helmet comprising a shell having a shock attenuation liner adjacent an interior portion of the shell and a fit system adjacent the interior portion for contacting portions of the cranium, the fit system comprising an elongate fluid impervious bladder that is substantially non-linear when positioned in a planar orientation and having a first end including an inlet port in fluid communication with the bladder, a second end remote from the first end, a first temple portion adjacent the first end of the bladder, a second temple portion adjacent the second end of the bladder, a first side portion adjacent the first temple portion, a second side portion adjacent the second temple portion, and a rear portion between the first and second side portions, the bladder defining a single continuous fluid flowpath between the first end and the second end for receiving fluid introducible into the bladder through the inlet port for expanding the bladder so that substantially the entire length of the bladder may be expanded to engage mutually facing portions of the cranium of the user and interior portions of the helmet, the bladder being positionable within the helmet so that the side portions substantially wrap around side portions of the cranium, the first and second temple portion are adjacent temple areas of the cranium, and the rear portion is adjacent a rear occipital protuberance portion of the cranium without compromising the fluid flow path.
