Abstract
Abstract An aerodynamically streamlined flexible protective helmet assembly comprising an outer layer of impact resistant segments (61-67) confined within fabric chambers overlying an inner layer of closely abutting impact resistant energy absorbing structures (71-77) confined within elastic fabric chambers and including an elliptically annular crown structure (78) confined within a fabric chamber.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
144 words
A flexible protective helmet assembly comprising an inner layer of a plurality of enclosed chambers formed from elastic textile fabric, the inner layer chambers each confining within them a discreet impact resistant and energy absorbing structure and forming the lower margins of the helmet, an integral fixedly attached overlying outer layer of a plurality of enclosed chambers formed from materials selected from the group consisting of flexible textile fabric and elastic textile fabric and leather, the outer layer chambers each confining within them a discreet impact resistant segment of material, a crown area, and means for attaching the inner layer chambers to adjacent inner layer chambers and attaching the outer layer chambers to the inner layer chambers whereby the wearer is provided protection from impacts substantially equivalent to that provided by protective helmets employing and comprising in part, substantially unitary relatively rigid outer shells.
Claim 2
Dependent Claim
144 words
A flexible protective helmet assembly comprising an inner layer of a plurality of enclosed chambers formed from elastic textile fabric, the inner layer chambers each confining within them a discreet impact resistant and energy absorbing structure and forming the lower margins of the helmet, an integral fixedly attached overlying outer layer of a plurality of enclosed chambers formed from materials selected from the group consisting of flexible textile fabric and elastic textile fabric and leather, the outer layer chambers each confining within them a discreet impact resistant segment of material, a crown area, and means for attaching the inner layer chambers to adjacent inner layer chambers and attaching the outer layer chambers to the inner layer chambers whereby the wearer is provided protection from impacts substantially equivalent to that provided by protective helmets employing and comprising in part, substantially unitary relatively rigid outer shells.
Claim 3
Dependent Claim
97 words
An assembly as in claim 1 wherein each said structure substantially conforms to the interior shape and dimensions of its corresponding confining inner layer chamber, said segments each substantially conforms to the interior shape and dimensions of its corresponding outer layer chamber, the inner layer chambers and structures extend longitudinally in an arcuate radial manner from the crown area of the helmet to the lower margins of said helmet, and the outer layer of chambers and segments extend in an arcuate radial manner from the crown area of the helmet to the lower margins of said helmet.
Claim 4
Dependent Claim
43 words
An assembly as in claim 1 wherein the inner layer chambers are attached to adjacent inner layer chambers along their longitudinal margins, and the outer layer chambers are attached to the inner layer chambers along the longitudinal margins of the outer layer chambers.
Claim 5
Dependent Claim
54 words
An assembly as in claim 1 wherein the central longitudinal aspects of the outer layer chambers and segments are substantially in alignment with and adjacent longitudinal attachments of the inner layer chambers, and longitudinal margins of the outer layer chambers and segments overly the longitudinal margins of the inner layer chambers by predetermined dimensions.
Claim 6
Dependent Claim
28 words
An assembly as in claim 1 wherein central aspects of the outer surfaces of the inner layer chambers are exposed between longitudinal margins of the outer layer chambers.
Claim 7
Dependent Claim
71 words
An assembly as in claim 1 further including an elliptically annular crown chamber formed from material selected from the group consisting of flexible textile fabric and elastic textile fabric and leather, said crown chamber confines within it a discreet impact resistant and energy absorbing structure, and means are included for attaching said crown chamber to the inner layer of chambers and attaching said crown chamber to the outer layer of chambers.
Claim 8
Dependent Claim
50 words
An assembly as in claim 6 wherein said structure confined in said crown chamber substantially conforms to the interior shape and dimensions of said crown chamber, and the greater planar dimensions of said crown chamber and said structure are substantially in alignment with the sagittal longitudinal plane of the helmet.
Claim 9
Dependent Claim
39 words
An assembly as in claim 6 wherein said crown chamber is attached along its perimeter to upper lateral margins of said inner layer of chambers and to upper lateral margins of said outer layer of chambers of the helmet.
Claim 10
Dependent Claim
44 words
An assembly as in claim 6 wherein the the outer surface material of said crown chamber and the structure confined within the crown chamber overlies the upper lateral margins of said inner layer of chambers and the structures confined within them a predetermined dimension.
Claim 11
Dependent Claim
16 words
An assembly as in claim 6 wherein said means for attaching said crown chamber includes stitching.
Claim 12
Dependent Claim
13 words
An assembly as in claim 1 wherein said means for attaching includes stitching.
Claim 13
Dependent Claim
31 words
An assembly as in claim 1 further including a releasably securable adjustable chinstrap, and means for attaching said chinstrap to said helmet, said means for attaching said chin strap including stitching.
