Abstract : An inflatable stabilization system located within a rigid helmet shell. The system is constructed of an inflatable bladder having a manifold located in the nape area of the helmet with four curved ducts branching off to extend forwardly over the occipital and crown areas of the wearer. The bladder is attached to the helmet shell by hook and pile fastener strips. A pressure difference sensor controls bladder pressure to maintain a desired pressure difference between the bladder and ambient pressure. When a cloth hat or liner is used with the helmet, the bladder is located between the hat and the helmet shell. (Author)
