Abstract: A buckle for receiving a strap member and for snap-fitting to a snap stud located on a helmet, the buckle including a metal member having opposite ends and opposite first and second substantially planar surfaces, with an aperture located between the ends and a slit on either side of the aperture, each of the slits including a plurality of rugous surfaces suitable for frictionally engaging a strap member positionable there through. A metal snap configured to be matingly engagable with the snap stud of the helmet is affixed adjacent to the first surface of the metal member by a fastener connectingly associated with the metal snap and the aperture of the metal member. A plastic material substantially encases the metal member except that at least a portion of the rugous surfaces and a portion of the first surface of the metal member adjacent the metal snap are not encased by the plastic material and remain exposed.

Abstract: A method of making a face mask including the steps of providing a plurality of lengths of Grade 2, commercially pure titanium wire, having a diameter of from about 0.21 to about 0.24 inches; forming each length at room temperature to a desired bend angle by bending the member at room temperature using rotary bending apparatus to a first bend angle that is from about 1.25 to about 1.35 times greater than the desired bend angle; and welding each of the thus formed lengths to at least one other of the lengths in an ambient, oxygen containing environment.

Abstract: A fit system positionable adjacent interior portions of a helmet and cranial surfaces of a cranium of a wearer of the helmet proximate the interior portions of the helmet for improving the fit of the helmet to the cranium. The system includes an elongate fluid impervious bladder having a first end including an inlet port in fluid communication with the bladder and a second end remote from the first end. The bladder defines 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 is positionable within the helmet so as to substantially wrap around side portions of the cranium, temple areas of the cranium, a rear occipital protuberance portion of the cranium and an upper portion of the cranium without compromising the fluid flow path.

Abstract: A helmet which includes a substantially rigid shell having a shell thickness defined by a substantially continuous exterior surface spaced apart from a substantially continuous interior surface. A one-piece first shock attenuating member is positioned adjacent to and in substantially in contact with portions of the interior surface of the shell. The first shock attenuating member has a first thickness and a first compression deflection. A plurality of discrete second shock attenuating members are positioned adjacent to portions of the first shock attenuating member and adjacent to and in substantially in contact with portions of the interior surface of the shell. Each second shock attenuating member has a second thickness and a second density, with the second thickness being greater than the first thickness and the second compression deflection being less than the first compression deflection.

The buckle includes a metal member having opposite ends, with an aperture located between the ends and a slit on either side of the aperture. Each of the slits including a plurality of rugous surfaces suitable for frictionally engaging a strap member positionable there through, and a plastic material substantially encasing the metal member except that at least a portion of the rugous surfaces are not encased by the plastic material and remain exposed, and a region surrounding the aperture of the metal member is not encased and the plastic material located adjacent the aperture defines a barrel configured for receiving and mating in a snap-fit relationship with a snap-stud fastener located on a helmet with which the buckle is to be used.
