Abstract
Abstract A shock shielding structure and method for shielding against shock by the use of inflated envelopes wherein said shielding is capable of functioning at peak reflected shocks of over 2,000 pounds per square inch to reduce the peak transmitted force by 70-90 percent or more. Still further, the shielding invention herein comprises a sheltering method and structure for use against the dangers incident to war and, more specifically, relates to a method or structure for use in shielding persons or equipment against the effects of nuclear explosion, and also toxic or corrosive gases and bacteria.
