Mounting system for helmets

The present invention relates to helmets. Specifically, the present invention relates to helmets having means of retaining eyewear, such as goggles, to the helmet. The present invention is directed to a helmet which includes a shell portion, a liner portion which is in the interior part of the helmet, and an insert portion which is embedded in the liner portion. The insert portion includes a mounting portion for one or more accessories, such as chin straps, side flaps, padding, and the like. The mounting liner provides structural integrity to the protective helmet, provides sufficient impact attenuation properties, and allows various items to be attached to the protective helmet, while still allowing the outer shell to be of lightweight construction. In one aspect, side portions about the ear are coupled to the insert portion. The side portions are rigid to provide support for side eyewear retaining portions that hold an eyewear elastic portion at the side of the helmet, thus preventing the eyewear from sliding off while resting atop the helmet.
