Abstract

Abstract An adjustable helmet suspension system for varying the height at which a met is worn on the head. A doubled strand of braid, or other type of cord, supports the suspension straps of the helmet suspension system. The doubled strand of braid is made adjustable in circumference, thereby controlling the degree to which the helmet suspension straps are drawn in over the head of the wearer. Adjustment of the circumference of the doubled strand of braid is accomplished rapidly by means of a hook and pile type fastener, the hook portion of which is attached to the ends of the doubled strand of braid while the pile portion is attached to the upper surface of one of the straps of the helmet suspension system.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 332 words
In an adjustable helmet suspension system for adjusting the height at which a helmet is worn on the head comprising a headband sized to fit snugly within said helmet and to be attached to the inner surface of said helmet at a plurality of points, a front suspension strap attached at one end thereof to said headband at approximately the midpoint of the front of said headband and having a loop formed at the free end thereof, and a rear suspension strap attached at one end thereof to said headband at approximately the midpoint of the rear of said headband and having a loop formed at the free end thereof, the improvement which comprises, a continuous strand of cord having two ends, said continuous strand of cord being threaded through the loops of said front and rear suspension straps in such a way as to form a doubled strand of said cord to support said front and rear suspension straps in operating position resting against the head of the wearer, said doubled strand being adjustable in circumference by having each of said two ends of said continuous strand of cord forming said doubled strand attached to a tab which comprises the hook elements of a hook and pile fastener and by having the pile element of said hook and pile fastener attached to said rear suspension strap, said pile element and said hook elements cooperating for adjustably fastening said tab at various positions along said rear suspension strap and firmly holding said tab with said doubled strand of cord adjusted to greater or smaller circumferences, said suspension straps being thereby rendered adjustable so that the ends thereof through which said continuous strand is threaded are spaced farther apart or closer together on the head of the wearer by the adjustment of the circumference of said doubled strand of cord, whereby the height at which a helmet containing said adjustable helmet suspension system is supported on the head of the wearer is adjustable.
Claim 2
Dependent Claim 332 words
In an adjustable helmet suspension system for adjusting the height at which a helmet is worn on the head comprising a headband sized to fit snugly within said helmet and to be attached to the inner surface of said helmet at a plurality of points, a front suspension strap attached at one end thereof to said headband at approximately the midpoint of the front of said headband and having a loop formed at the free end thereof, and a rear suspension strap attached at one end thereof to said headband at approximately the midpoint of the rear of said headband and having a loop formed at the free end thereof, the improvement which comprises, a continuous strand of cord having two ends, said continuous strand of cord being threaded through the loops of said front and rear suspension straps in such a way as to form a doubled strand of said cord to support said front and rear suspension straps in operating position resting against the head of the wearer, said doubled strand being adjustable in circumference by having each of said two ends of said continuous strand of cord forming said doubled strand attached to a tab which comprises the hook elements of a hook and pile fastener and by having the pile element of said hook and pile fastener attached to said rear suspension strap, said pile element and said hook elements cooperating for adjustably fastening said tab at various positions along said rear suspension strap and firmly holding said tab with said doubled strand of cord adjusted to greater or smaller circumferences, said suspension straps being thereby rendered adjustable so that the ends thereof through which said continuous strand is threaded are spaced farther apart or closer together on the head of the wearer by the adjustment of the circumference of said doubled strand of cord, whereby the height at which a helmet containing said adjustable helmet suspension system is supported on the head of the wearer is adjustable.
Claim 3
Dependent Claim 37 words
An adjustable helmet suspension system according to claim 1, wherein said pile element of said hook and pile fastener is attached to said front suspension strap so as to cooperate with said hook elements of said tab.
Claim 4
Dependent Claim 50 words
An adjustable helmet suspension system according to claim 1, wherein said rear suspension strap has hook elements of a hook and pile fastener attached thereto and said tab has pile elements of a hook and pile fastener attached thereto to cooperate with said hook elements of said rear suspension strap.
Claim 5
Dependent Claim 50 words
An adjustable helmet suspension system according to claim 2, wherein said front suspension strap has hook elements of a hook and pile fastener attached thereto and said tab has pile elements of a hook and pile fastener attached thereto to cooperate with said hook elements of said front suspension strap.
Claim 6
Dependent Claim 63 words
An adjustable helmet suspension system according to claim 1, wherein said helmet suspension system also comprises side suspension means supported by said doubled strand of said cord between said front and rear suspension straps along the sides of said headband when said helmet suspension system is in its operating position with said side suspension means also resting against the head of the wearer.
Claim 7
Dependent Claim 117 words
An adjustable helmet suspension system according to claim 1 wherein said helmet suspension system also comprises two side suspension straps, the two ends of each side suspension strap being attached to said headband at spaced apart points along one of the two sides of said headband, each of said side suspension straps forming a loop approximately midway between said two ends thereof, said doubled strand of said cord also being threaded through the loops of said side suspension straps, whereby said side suspension straps are also supported by said doubled strand of said cord when said helmet suspension system is in its operating position with said side suspension straps also resting against the head of the wearer.
Claim 8
Dependent Claim 119 words
An adjustable helmet suspension system according to claim 1, wherein said loop formed at the free end of said rear suspension strap has two eyes mounted in and passing through the upper arm of said loop, said eyes being spaced apart along a line passing through the centers thereof substantially perpendicular to the side edges of said rear suspension strap, each of the two ends of said strand of cord being threaded through one of said eyes and thereafter both of said ends of said strand of cord being threaded side-by-side through a loop of fabric formed in said tab, said two ends of said strand of cord being stitched to the fabric forming said loop of said tab.
