Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
88 words
A protective helmet comprising: an outer shell; a liner disposed within said shell including a plurality of inflatable air compartments and a number of air channels interconnecting said compartments; and a self-contained tactile actuatable pump, mounted to said helmet interiorly of said outer shell so as to be carried thereby even when said helmet is in use, said pump being in fluid communication with at least on of said compartments, whereby actuation of said air pump causes air to flow from said air pump to said air compartments.
Claim 2
Dependent Claim
88 words
