Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
99 words
A protective pad means having the capability to absorb the force of a blow comprising: an outer layer and an inner layer of material forming an envelope; a plurality of spring columns mounted interiorly to said envelope; and air passages internal to said envelope and surrounding said spring columns whereby, when said pad means is impacted, said outer and inner layers of the envelope restrict air flow from said air passages so as to form an air cushion that operates in conjunction with said inner and outer layers and said spring columns to absorb the force of the blow.
Claim 2
Dependent Claim
