Abstract
Abstract The head suspension consists of a continuous rigid outer strap and an inner strap. The outer strap is secured to the inside of the shell of a helmet and consists of a number of tightly stretched loops and links which in part define a continuous band spaced apart from the shell. The inner strap extends circumferentially with the outer strap to contact the wearer''s head and is connected to the outer strap preferably at four only points spaced along the inner strap length. Preferably the inner strap is composed of three segments disposed in end-to-end relationship. The segments have overlapping end portions disposed between all but one pair of adjacent points and means is provided for adjusting the overlap of the end portions. The crown suspension consists of upper and lower dome-shaped elements each having a central portion and radially extending legs. The legs of the upper element are connected to the shell and means is provided for adjusting the position of the legs of the lower element relative to the upper element legs to enable the lower element to be fitted to various sized heads.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
171 words
A head suspension for use within a protective helmet having a shell adapted to encircle a weareR''s head and in spaced relationship thereto, said head suspension including: a outer strap composed of a plurality of loops and links, said loops being disposed circumferentially in side by side relationship, successive said loops being connected by a respective said link, said loops adapted to be secured at positions along the inside of the shell in such manner that said loops and links are tightly stretched and such that said links and a portion of said loops define a continuous band which is spaced apart from said shell and which encircles the wearer''s head at approximately the level with respect to the wearer''s head of a normal hat band, said head suspension further including an inner strap connected to said outer strap and adapted to contact the wearer''s head at least in part at said level, and means for adjusting the effective length of said inner strap to increase or decrease the size thereof.
Claim 2
Dependent Claim
171 words
A head suspension for use within a protective helmet having a shell adapted to encircle a weareR''s head and in spaced relationship thereto, said head suspension including: a outer strap composed of a plurality of loops and links, said loops being disposed circumferentially in side by side relationship, successive said loops being connected by a respective said link, said loops adapted to be secured at positions along the inside of the shell in such manner that said loops and links are tightly stretched and such that said links and a portion of said loops define a continuous band which is spaced apart from said shell and which encircles the wearer''s head at approximately the level with respect to the wearer''s head of a normal hat band, said head suspension further including an inner strap connected to said outer strap and adapted to contact the wearer''s head at least in part at said level, and means for adjusting the effective length of said inner strap to increase or decrease the size thereof.
Claim 3
Dependent Claim
171 words
A head suspension for use within a protective helmet having a shell adapted to encircle a weareR''s head and in spaced relationship thereto, said head suspension including: a outer strap composed of a plurality of loops and links, said loops being disposed circumferentially in side by side relationship, successive said loops being connected by a respective said link, said loops adapted to be secured at positions along the inside of the shell in such manner that said loops and links are tightly stretched and such that said links and a portion of said loops define a continuous band which is spaced apart from said shell and which encircles the wearer''s head at approximately the level with respect to the wearer''s head of a normal hat band, said head suspension further including an inner strap connected to said outer strap and adapted to contact the wearer''s head at least in part at said level, and means for adjusting the effective length of said inner strap to increase or decrease the size thereof.
Claim 4
Dependent Claim
171 words
A head suspension for use within a protective helmet having a shell adapted to encircle a weareR''s head and in spaced relationship thereto, said head suspension including: a outer strap composed of a plurality of loops and links, said loops being disposed circumferentially in side by side relationship, successive said loops being connected by a respective said link, said loops adapted to be secured at positions along the inside of the shell in such manner that said loops and links are tightly stretched and such that said links and a portion of said loops define a continuous band which is spaced apart from said shell and which encircles the wearer''s head at approximately the level with respect to the wearer''s head of a normal hat band, said head suspension further including an inner strap connected to said outer strap and adapted to contact the wearer''s head at least in part at said level, and means for adjusting the effective length of said inner strap to increase or decrease the size thereof.
Claim 5
Dependent Claim
211 words
A head suspension for use within a protective helmet having a shell adapted to encircle a wearer''s head and in spaced relationship thereto, said head suspension consisting of a continuous rigid outer strap adapted to extend within said shell and to be secured at positions spaced along the length thereof to the inside of the shell at approximately the level with respect to the wearer''s head of a normal hat band, an inner strap adapted to contact a wearer''s head and extending circumferentially within said outer strap, said inner strap being connected to said outer strap at four only points spaced along the length of said inner strap such that said inner strap is adapted to be maintained rigidly in position within and spaced apart from said shell, said inner strap being composed of a plurality of segments disposed in generally end-to-end relationship, said segments having overlapping end portions disposed between all but one pair of adjacent said points, the distance between the pair of said points lacking said overlapping end portions being less than the distance between the remaining pairs of said points, and means for adjusting the amount of overlap of said end portions to vary the circumference of the inner strap to increase or decrease the size thereof.
Claim 6
Dependent Claim
211 words
A head suspension for use within a protective helmet having a shell adapted to encircle a wearer''s head and in spaced relationship thereto, said head suspension consisting of a continuous rigid outer strap adapted to extend within said shell and to be secured at positions spaced along the length thereof to the inside of the shell at approximately the level with respect to the wearer''s head of a normal hat band, an inner strap adapted to contact a wearer''s head and extending circumferentially within said outer strap, said inner strap being connected to said outer strap at four only points spaced along the length of said inner strap such that said inner strap is adapted to be maintained rigidly in position within and spaced apart from said shell, said inner strap being composed of a plurality of segments disposed in generally end-to-end relationship, said segments having overlapping end portions disposed between all but one pair of adjacent said points, the distance between the pair of said points lacking said overlapping end portions being less than the distance between the remaining pairs of said points, and means for adjusting the amount of overlap of said end portions to vary the circumference of the inner strap to increase or decrease the size thereof.
Claim 7
Dependent Claim
78 words
The head suspension as claimed in claim 1, wherein said inner strap extends in one part at approximately the level with respect to the wearer''s head of a normal hat band and in the other part at a level below that of the normal hat band, said first part adapted to extend between the two temporal bones and across the frontal bone of the wearer while the other part adapted to contact the base of the occipital bone.
Claim 8
Dependent Claim
53 words
The head suspension as claimed in claim 1 wherein said inner band adjusting means comprises a plurality of apertures formed in one of each pair of overlapping end portions and outwardly extending studs formed in the other of each pair of overlapping end portions, said studs being releasably engageable in selective said apertures.
Claim 9
Dependent Claim
