Definitions

  • This disclosure generally relates to helmets, especially motorcycle helmets, especially full face helmets.
  • the disclosure further relates to helmets, especially motorcycle helmets, comprising air filters for the breathing air of a person wearing the helmet and to helmet having a non-breathable fabric or similar closing the lower opening of the helmet which accommodates the neck of a person wearing the helmet.
  • Full face helmets usually comprise an outer shell with two main openings, the front opening being coverage by a visor, the lower opening going over the head of a person putting on the helmet and accommodating the neck of a person wearing the helmet.
  • WO Publication WO 99/62364 A1 shows a full face helmet comprising a flat filter mat below the visor area of the helmet. As the area of the filter is geometrically limited, the filter cannot be very efficient as the breathing resistance would be too high otherwise. Also, the helmet has other openings allowing air to enter the helmet, reducing the efficiency of the filter mat.
  • a helmet especially a full face helmet, comprising an outer shell, a lower opening in the outer shell going over the head of a person putting on the helmet and accommodating the neck of a person wearing the helmet, a closed or closable visor, an air intake opening in the outer shell for breathing air, preferably located below the visor, a receiving space adapted to receive an air filter element ventilation insert inside the shell, the air intake open- ing allowing air to flow from the outside of the outer shell to the receiving space, and a removable air filter element, preferably comprising a pleated filter bellow of filter media, wherein the air filter element is sealingly positioned in the receiving space.
  • the advantage of using a pleated filter element inside the shell of the helmet allows for providing more filter media area.
  • the media can be selected to be of a higher filtration grade, as the restriction of the filter decreases with increasing the filter area.
  • Filter media can be preferably selected from media having filter classes G1 , G2, G3, G4, M5, M6, F7, F8, F9 according to EN 779.
  • the filter media can comprise a single or multiple layers of paper, woven or non-woven filter media.
  • the media can comprise or consist of layers of textile media, synthetic nonwoven media, cellulose media, paper media laminated with fine or nano-fiber layers, active carbon particle layers, laminated paper media layersorfiber glass blended paper, non-woven or fabrics.
  • the helmet further comprises an air intake grille provided on the air intake opening. This protects the air intake opening from bigger objects like insects entering the air intake opening.
  • the air filter element comprises a hydrophobic layer of filter media. This media preferably is facing the air intake opening. In this way, the amount of humidity entering the inside of the helmet can be reduced.
  • the air filter element comprises sealing means for sealingly contacting the receiving space.
  • the sealing means can be provided as a molded bead surrounding the air filter element, especially made from polyurethane, or a textile or non-woven side band covering the side edges of the air filter element and adapted to abut against the side wall of the receiving space.
