Definitions

  • Protective headgear and helmets have been used in a wide variety of applications and across a number of industries including sports, athletics, construction, mining, military defense, and others, to prevent damage to a user's head and brain. Damage and injury to a user can be prevented or reduced by helmets that prevent hard objects or sharp objects from directly contacting the user's head. Damage and injury to a user can also be prevented or reduced by helmets that absorb, distribute, or otherwise manage energy of an impact.
  • a helmet that fits properly is important for both comfort and protection.
  • helmets are available in multiple sizes; however, due to a wide spectrum of head sizes, further adjustments may be needed for a proper fit.
  • Conventional helmets often make use of fit adjustment systems wrapping around the rear of the head near the occipital bone.
  • United States Patent Application 14/833,779 (hereinafter the '779 application) describes a helmet with a fit adjustment system including a strap across the occipital region and a device to adjust the fit.
  • Conventional helmets having a fit adjustment system are problematic for users with long hair, which must be pulled through an opening with closed borders between the fit system and the helmet body. This additional step slows down the process of putting on and taking off the helmet. Furthermore, long hair often has to be braided or otherwise arranged to facilitate pulling through the opening. Additionally, conventional helmets, including those disclosed in the '779 application, typically position a fit adjustment mechanism in the center of the occipital region. A wearer's long hair may block access to the adjustment mechanism, or worse, get tangled within the moving parts. Attempts by users of conventional helmets to avoid these problems sometimes results in ill-fitting helmets that provide reduced protection.
