Problems solved by technology

A problem with this method of sizing helmets is that the helmets are sized based on universal standards that are not specific to any individual who will actually wear and depend on the helmet for head protection.
While a standard sized helmet may provide adequate protection in some instances, it is not fitted to the unique shape and contour of the particular wearer's head, and therefore is prone to fit too tightly in certain aspects or along certain locations of the head while fitting too loosely in others.
A too loosely fitting helmet can be harmful because the initial impact against the outer helmet s

Embodiment Construction

[0024] As used herein, when a range such as 5 to 25 (or 5-25) is given, this means preferably at least 5 and, separately and independently, preferably not more than 25.

[0025] One method of the present invention includes first making a headform that conforms to the shape of the wearer's head. The headform is made by positioning or wrapping an appropriate shape-forming means over and against the wearer's head. When the shape-forming means is applied to the head, it is in a softened or flexible state such that it can bend or flex or stretch to conform to the unique contour of the individual head to which it is being applied. Once the shape-forming means has been applied and conformed snugly to individual's head, it is hardened or rigidized such that it is no longer soft or flexible, thereby yielding a hardened headform 60 that conforms or substantially conforms to the shape and contour of the wearer's head.

[0026] Once hardened, the headform is carefully removed from the wearer's head...

Abstract

A helmet liner that is custom-fitted to a wearer's head, and methods of making the liner, are provided. To make the liner, scanning equipment directly scans the person's head to generate computer-readable data containing a surface map of the head. This data then is used by suitable machining equipment to machine a custom-fitted liner from a universal liner blank, whose resulting convex surface will substantially conform to the shape and contour of the person's head. The scanning equipment desirably is or includes one or a plurality of lasers. A mobile platform including both the scanning and the machining equipment also is provided.
