Definitions

  • Head gear such as helmets utilized, e.g., in military and police applications, have been developed that support one or more accessories such as flashlights or cameras. These accessories can assist the wearer in performing various tasks. For example, flashlights can be utilized to allow the wearer to more easily see the immediate surroundings. Frequently, the position of the flashlight or other accessory may need to be adjusted, or the accessory may need to be removed and replaced with another accessory. Further, two or more accessories may need to be utilized concurrently. When no accessories are required, the weight of the head gear can be reduced by removing such accessories.
  • various mounting systems have been developed that can be connected to the helmet.
  • Such systems often include a rail or groove within which a mount attached to an accessory can be disposed.
  • the rail can allow a wearer to adjust the accessory relative to the helmet.
  • a rail is typically mounted onto the helmet by drilling one or more holes through the helmet and inserting a bolt through the rail and helmet that is fastened to the helmet with a nut disposed within an interior space of the helmet.
  • this method of attaching the rail to the helmet can be robust, the one or more holes drilled through the helmet can weaken the helmet. Further, one or both of the bolt and nut can become a secondary projectile that could impact the wearer's head when the helmet encounters a ballistic event.
  • some helmets include one or more bosses of non-ballistic material that can be molded into an external surface of the helmet.
  • An accessory rail can be attached to the bosses with self-tapping screws that are directed into the bosses. This design does not, however, allow repeated removal and reattachment of the rail from the helmet as threads formed in the bosses by the screws (or preformed) tend to become stripped. Once the threads are stripped, the bosses will no longer hold the rail in place, and the entire helmet has to be discarded.
  • the present disclosure provides various embodiments of an accessory mounting system and a helmet that includes such system.
  • the accessory mounting system can include a plate and an accessory rail that is adapted to be removably connected to the plate.
  • the plate can be connected to the helmet without the need to dispose holes through the helmet or to form molded bosses in the helmet.
  • the plate is adapted to be permanently connected to a substantially continuous portion of a ballistic layer of a helmet.
  • the present disclosure provides an accessory mounting system that includes a plate adapted to be permanently connected to a substantially continuous portion of a ballistic layer of a helmet, where the ballistic layer includes an outer surface.
  • the plate includes an inner surface and an outer surface, where the inner surface of the plate is adapted to be disposed in contact with an outer surface of the ballistic layer.
  • the accessory mounting system also includes an accessory rail adapted to be removably connected to the plate, where the accessory rail includes an inner surface and an outer surface. The inner surface of the accessory rail is adapted to be disposed in contact with the plate.
  • the present disclosure provides a helmet that includes a ballistic layer having an inner surface and an outer surface, and an accessory mounting system that includes a plate and an accessory rail removably connected to the plate.
  • the plate includes an inner surface and an outer surface, where the inner surface of the plate is permanently connected to a substantially continuous portion of the ballistic layer by an attachment element.
  • the accessory rail includes an inner surface and an outer surface. Further, the inner surface of the accessory rail is in contact with the plate when the accessory rail is connected to the plate.
  • the present disclosure provides a method that includes connecting a plate to an outer surface of a ballistic layer of a helmet, connecting an accessory rail to the plate, and connecting an accessory to the accessory rail.
  • the method further includes removing the accessory from the accessory rail, and removing the accessory rail from the plate by moving the accessory rail in a direction orthogonal to an outer surface of a ballistic layer of the helmet.
  • the present disclosure provides a method that includes disposing a template on an outer surface of a ballistic layer of a helmet, where the template includes an opening that exposes a portion of the ballistic layer; disposing an adhesive on the exposed portion of the ballistic layer through the opening of the template; and connecting a plate to the exposed portion of the ballistic layer utilizing the adhesive.
  • the method further includes applying pressure to the plate, and curing the adhesive such that the plate is permanently attached to the ballistic layer of the helmet.
  • the present disclosure provides an accessory mounting system kit that includes a template adapted to be disposed on an outer surface of a ballistic layer of a helmet, where the template includes an opening that is adapted to expose a substantially continuous portion of the ballistic layer of the helmet.
  • the kit further includes an adhesive, a surface cleaning component adapted to clean the substantially continuous portion of the ballistic layer of the helmet, and an abrasive element adapted to abrade the substantially continuous portion of the ballistic layer of the helmet.
