A safety helmet fan system includes a fan housing carrying a first fan on a first side of the fan housing and a second fan on a second side of the fan housing and configured to be mounted, by a mount connector located between the first side and the second side, on an exterior of a safety helmet shell above a brim of the safety helmet shell, and an elongate cooling air duct connected to the fan housing to direct cooling air flow from the fan housing around the brim and into an interior of the safety helmet shell.

Various embodiments of helmets and methods of their manufacture are disclosed. In some embodiments, the helmet includes a helmet shell having a helmet shell edge and/or a mounting location for mounting an accessory to the helmet shell. A material that is adherent to the helmet shell may be sprayed onto the helmet shell edge of the helmet shell to form a trim. Alternatively, the material may be sprayed onto a portion of the helmet shell associated with either a mounting location for mounting an accessory or a position for a mounted accessory.

The invention relates to a protective sports helmet purposely designed for a selected group of helmet wearers from amongst a larger population of helmet wearers. A multi-step method for helmet design starts by collecting information from a population of players that may include information about the shape of a player's head and the impacts the player has sustained. This information is then processed to create player population information that is sorted to create categories. Advanced mathematical techniques are utilized to further sort these categories into player groups or data sets based on player attributes. Once the player groups are identified, another multi-step process is utilized to design optimized helmet prototype models for each player group. These optimized helmet prototype models are then further processed into complete helmet models by determining a structural design and chemical composition that is manufacturable and has mechanical properties that are substantially similar to the optimized helmet prototype model. Physical helmet prototypes are then created and tested using a unique helmet standard derived from information associated with each player group. Once the prototypes pass testing, the complete helmet models can be manufactured to create actual stock helmets or stock helmet components for future players whose characteristics and attributes place them within the selected player group.
