Abstract: There is provided a safety helmet with a helmet fitting and impact attenuation system. The system comprises a semi-rigid space frame attachable to the safety helmet and a headband, releasably attachable to one or more arms of the space frame. The space frame and headband accommodate the use of an impact attenuation liner mounted between the space frame and the helmet shell. The helmet fitting and impact attenuation system also may be used to update and retrofit existing helmet shells.

Abstract: There is provided a blast occurrence apparatus for indicating the occurrence of a significant and potentially injury causing blast overpressure. The apparatus comprises a base, a housing and blast indication means to provide a visual indication that a significant blast has occurred. A blast indication means may be implemented using a rupturable membrane or a layer of microencapsulated paint or dye material, dimensioned to rupture at the desired overpressure level. The device is configured to withstand acceleration or shock resulting from impact.

Abstract: A comfortable, self-adjusting, protective helmet made from a process of insert molding. The helmet comprises an armature or insert made of a porous material that is embedded in the layers of the helmet to connect the structural parts of the helmet to one another. The armature as used in the helmet also serves several other functions which include hinging and sizing. A retention system is strategically located on the helmet to provide increased stabilization of the helmet on the wearer's head. One embodiment of this invention is an insert-molded helmet that can be converted into a pouch. A further embodiment of this invention includes a protrusion at the back of a helmet suitable for a compartment.

Abstract: A new process for making headgear. The process comprises the step of insert molding an armature into helmet segments to produce a protective helmet having superior characteristics. The process also comprises the step of strategically locating a retention system on the helmet to provide increased stabilization of the helmet on the wearer's head. The process further comprises the step of attaching an improved strap guide to the helmet. One embodiment of this invention is a process for making an insert-molded helmet that can be converted into a pouch. Another embodiment of this invention is a process for making a helmet that includes a protrusion at the back of a helmet suitable for a compartment.

Abstract: Existing devices for stabilizing a safety helmet such as a hard hat are either unduly complicated or ill adapted as retrofits for existing helmets. A simple restraining device for use on new or existing helmets includes a bracket located at the center of the interior of each side of the helmet for pivotally supporting front and rear headbands. Pins extending through the headbands into arcuate slots in the brackets limit rotation of the front and rear headbands with respect to the brackets. A force tending to lift or rotate the helmet from the wearer's head will cause the headbands to pivot downwardly and inwardly against the wearer's head, thus inhibiting removal thereof from the head of the wearer.

Abstract: A motorcycle accident simulating test dummy and method utilizing the test dummy wherein the test dummy includes motorcycle handle bar grips operable to releasably connect the dummy and motorcycle handle bar, frangible limb/joint structure, and a wholly self contained and test dummy protected, accident condition data acquisition unit.
