Headgear with a spring buffered occipital cradle
View Patent ↗A headgear for a head safety product such as a face shield, hardhat or welding helmet includes a spring buffered cradle mounted on the horizontal band of the headgear to improve the fit, function, stability and comfort of the headgear. The cradle is flexible and has a concave inner surface contoured to conform to the shape of the head. A spring element is coupled between the cradle and the horizontal band to buffer the tension between the band and the head and more equally distribute pressure across the head. In a preferred embodiment, an occipital cradle includes two leaf springs coupled to the rear portion of the horizontal band.
1. A headgear comprising:
a horizontal band configured to encircle the user's head,
said horizontal band including a front portion configured to extend across a forehead area of the user and a rear portion configured to extend across an occipital area of the head of the user;
an adjustment mechanism configured and arranged to adjust a circumference of the horizontal band;
a flexible cradle having a left lobe ring and a right lobe ring which are connected by a central web,
said left lobe ring having an open central portion and a generally three-dimensionally concave inner surface such that in an unstressed state said left lobe ring is contoured to conform to a left occipital lobe portion of the head;
said right lobe ring having an open central portion and a generally three-dimensionally concave inner surface such that in an unstressed state said right lobe ring is contoured to conform to a right occipital lobe portion of the head;
a first buffer spring coupled between said left lobe ring of said cradle and said rear portion of said horizontal band; and
a second buffer spring coupled between said right lobe ring of said cradle and said rear portion of said horizontal band,
said first and second buffer springs cooperating with said flexible cradle to buffer tension between said horizontal band and said head and dispose said flexible cradle away from said horizontal band when the user is not wearing the headgear.
2. The headgear of claim 1 wherein said rear portion of said horizontal band angles downwardly and rearwardly below an equatorial region of the head, said cradle cupping said occipital area below said equatorial region.
3. The headgear of claim 1 wherein said first and second buffer springs each comprise a leaf spring having a first end coupled to a terminal end portion of said lobe rings and a second mounting end extending rearwardly and inwardly back toward said central web where said second mounting end is coupled to said horizontal band.
4. The headgear of claim 3 wherein said second mounting end comprises a loop that slidably encircles said horizontal band.
5. The headgear of claim 3 wherein said first and second leaf springs are integrally formed with said cradle, said leaf springs each having a proximal first end integrally formed with said cradle and a distal second end formed in the shape of a loop that slidably encircles said horizontal band.
6. The headgear of claim 1 wherein said flexible cradle includes a compressible pad on said inner surfaces of said lobes.
7. An occipital cradle for use with a headgear having a horizontal band encircling the head, said cradle comprising:
a flexible body portion having symmetrical left and right lobe rings,
said left lobe ring having an open central portion and a generally three-dimensionally concave inner surface such that in an unstressed state, said left lobe ring is contoured to conform to a left occipital lobe portion of the head;
said right lobe ring having an open central portion and a generally three-dimensionally concave inner surface such that in an unstressed state, said right lobe ring is contoured to conform to a right occipital lobe portion of the head;
a first buffer spring having a proximal first end integrally formed with and extending outwardly and rearwardly from a rear outer surface of said left lobe ring of said body portion, and further having a distal second end formed in the shape of a loop that slidably encircles said horizontal band; and
a second buffer spring having a proximal first end integrally formed with and extending outwardly and rearwardly from a rear outer surface of said right lobe ring of said body portion, and further having a distal second end formed in the shape of a loop that slidably encircles said horizontal band,
said first and second buffer springs buffering pressure between said horizontal band and the occipital area of the head and disposing said body portion away from said horizontal band when the user is not wearing the headgear.
8. The headgear of claim 5 wherein said flexible cradle includes a compressible pad on said inner surfaces of said lobes.
9. The cradle of claim 7 wherein said first and second buffer springs each comprise a leaf spring having a first end coupled to a terminal end portion of said lobe rings and a second mounting end extending rearwardly and inwardly back toward said central web where said second mounting end is coupled to said horizontal band.
10. A headgear of the type comprising a horizontal band configured to encircle a user's head, the horizontal band including a front portion configured to extend across a forehead area of the user and a rear portion configured to extend across an occipital area of the user's head when the user wears the headgear, the headgear further comprising an adjustment mechanism configured to adjust a circumference of the horizontal band, the headgear being characterized by
a flexible cradle having a left lobe ring and a right lobe ring which are connected by a central web, each of the left lobe ring and the right lobe ring having an open central portion and a generally three-dimensionally concave inner surface such that in an unstressed state each of the left lobe ring and the right lobe ring are contoured to circumferentially conform to a corresponding left and right occipital lobe portion of the user's head when the user wears the headgear,
the headgear being further characterized by first and second buffer springs that respectively couple the left lobe ring and the right lobe ring to the horizontal band in a manner that disposes the flexible cradle away from the horizontal band when the user is not wearing the headgear.
11. The headgear of claim 10 wherein the rear portion of the horizontal band angles downwardly and rearwardly below an equatorial region of the head, the flexible cradle cupping an occipital area below the equatorial region of the user's head.
12. The headgear of claim 10 wherein said first and second buffer springs each comprise a leaf spring having a first end coupled to a terminal end portion of said lobe rings and a second mounting end extending rearwardly and inwardly back toward said central web where said second mounting end is coupled to said horizontal band.
13. The headgear of claim 12 wherein the second mounting end comprises a loop that slidably encircles the horizontal band.
14. The headgear of claim 12 wherein the first and second leaf springs are integrally formed with the cradle, the leaf springs each having a proximal first end integrally formed with the cradle and a distal second end formed in the shape of a loop that slidably encircles the horizontal band.
15. The headgear of claim 10 wherein the flexible cradle includes a compressible pad on said inner surfaces of the lobe rings.
16. The headgear of claim 10 wherein the flexible cradle includes a compressible pad on said inner surfaces of the lobe rings.
