ABSTRACT:
Helmets, shoulder pads, thigh pads and other protective equipment employ a cushioning fluid such as a layer of compressed air to protect both the wearer and an opposing player in contact sports. The helmet or other device has outer and inner walls of resilient material spaced apart to form an air chamber. A central plastic shield disposed between the resilient walls imparts shape and rigidity to the device and has multiple perforations to equalize the air pressure throughout the chamber when the walls flex under impact.
