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 a 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; and
an integrally formed flexible cradle having a left lobe and a right lobe which are connected by a central web,
said flexible cradle including a first buffer spring coupled between said left lobe of said cradle and said rear portion of said horizontal band, and a second buffer spring coupled between said right lobe 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,
said first and second buffer springs each comprising a leaf spring having a first end coupled to an end portion of a respective lobe 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, said second mounting end comprising a vertically extending loop that loosely encircles said horizontal band whereby said cradle is slidably movable and tilts relative to said horizontal band,
whereby each of said leaf springs is configured to spring-bias the respective mounting end away from said flexible cradle.
2. The headgear of claim 1 wherein said flexible cradle includes a compressible pad on said inner surfaces of said lobes.
3. A flexible cradle for use with a headgear having a horizontal band configured for encircling a user's head, said cradle comprising a left lobe and a right lobe which are integrally formed with and connected by a central web,
said cradle including a first buffer spring coupled between said left lobe of said cradle and said rear portion of said horizontal band, and a second buffer spring coupled between said right lobe 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,
said first and second buffer springs each comprising a leaf spring having a first end coupled to an end portion of a respective lobe 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, said second mounting end comprising a vertically extending loop that loosely encircles said horizontal band whereby said cradle is slidably movable and tilts relative to said horizontal band,
whereby each of said leaf springs is configured to spring-bias the respective mounting end away from said flexible cradle.
4. The cradle of claim 3 further comprising a compressible pad on said inner surfaces of said lobes.
