Abstract

A protective helmet having an outer shell and an inner liner is disclosed. The liner includes a plurality of air compartments interconnected by a number of air channels. A self-contained, tactile actuatable air pump is mounted to the helmet so as to be carried thereby even when the helmet is in use.

Claims

1. 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.

2. The helmet defined in claim 1, further including an air passage between said pump and said at least one of said compartments.

3. The helmet defined in claim 1, further including an air check valve disposed between said air pump and said at least one of said air compartments for permitting air to flow from said pump to said at least one of said air compartments, but substantially blocking the flow of air from said at least one of said air compartments to said air pump.

4. The helmet defined in claim 3, further including an air passage between said pump and said at least one of said air compartments, wherein said check valve is disposed within said air passage.

5. The helmet defined in claim 1, further including valve means for releasing air from said air compartments.

6. The protective helmet defined in claim 1, wherein said liner includes shock absorbent material which is not in fluid communication with said pump.

7. A protective helmet comprising:

an outer shell;

an inner liner disposed within said shell including at least one inflatable air compartment; and

a self-contained tactile actuatable air 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 said air compartment, whereby actuation of said air pump causes air to flow from said air pump to said air compartment.

8. A protective helmet comprising:

a liner formed of shock absorbent material, defining at least a portion of the exterior of said helmet;

a plurality of inflatable air compartments mounted to said helmet; and

a self-contained tactile actuatable air 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 said air compartments whereby actuation of said pump causes air to flow from said air pump to said air compartments.
