Patent number: 6591428Abstract: 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.Type: GrantFiled: February 15, 2002Date of Patent: July 15, 2003Assignee: Southern Impact Research Center, LLCInventors: P. David Halstead, Cherie F. Alexander

Patent number: 6434755Abstract: 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.Type: GrantFiled: June 2, 2000Date of Patent: August 20, 2002Assignee: Southern Impact Research Center, LLCInventors: P. David Halstead, Cherie F. Alexander, Thad Ide

Patent number: 6371710Abstract: An attachment system including an attachment member having a height and a width with a base and a main body having a height extending away from the base and being substantially flexible along the height thereof and substantially inflexible along its width. The main body includes a plurality of substantially inflexible portions vertically spaced apart from the base and from one another by a plurality of substantially flexible connecting portions.Type: GrantFiled: September 5, 2000Date of Patent: April 16, 2002Assignee: Southern Impact Research Center, LLCInventors: Thad Ide, P. David Halstead, Cherie F. Alexander

Patent number: 6324701Abstract: A chin strap system a pair of elongate straps and a substantially rigid cup anatomically configured for receiving a chin of a user. Four apertures extend between an inner and outer surface of the cup for receiving the straps. The straps are adjustably positionable through the apertures so that the straps crisscross one another adjacent the outer surface of the cup between the apertures. Each strap has a pair of free ends extending in opposite directions from the cup and include fasteners operatively for fastening the straps to a helmet with which the strap is to be used.Type: GrantFiled: September 1, 2000Date of Patent: December 4, 2001Inventor: Cherie F.
