Definitions

  • Vehicle with a system for protecting passengers and crew members from airborne pathogens
  • the invention relates to a vehicle featuring a system for protecting passengers from airborne pathogens, a combination of such a vehicle with a breathing mask being connectable with the system as well as suitable breathing mask.
  • Passengers on board of a vehicle are at risk of being infected with an airborne pathogen being present in aerosols exhaled or secreted by other passengers or members of the crew of the vehicle, such as attendant, driver or the like.
  • the risk is especially high in vehicles transporting large numbers of passengers for hours in a cabin with a confined space, like buses, trains, ferries or aircraft.
  • a single passenger or crew member infected with a disease spread by an airborne pathogen may infect a large number of passengers or crew members during a journey in said vehicle.
  • suitable protection of passengers as well of crew members is crucial for the safe operation of the vehicle.
  • an operator of a vehicle comprising such a protection system would have an economical advantage in such a situation compared to competitors operating vehicles without a protection system.
  • the protection system may also be an advantage during flu season, as it would offer passengers the possibility to protect themselves if wanted. Further, vulnerable passengers, like passengers suffering from immunodeficiency could protect themselves during journeys with such vehicles. Summary of the invention
  • a vehicle has a system for protecting passengers and crew members of the vehicle from airborne pathogens.
  • the vehicle comprises a multitude of seats for passengers, the seats being arranged in rows within a cabin of the vehicle.

  • a passenger or crew member may connect a breathing mask with a connection element located near his seat or row of seats. By doing so, the passenger or crew member is able to breathe uncontaminated fresh air, thus eliminating the risk of being infected by another passenger or crew member.
  • the vehicle may be any vehicle intended for the transport of a multitude of passengers, especially intended for the commercial transport of passengers.
  • the inventive vehicle may be a taxi, minibus, bus, coach, train carriage, ferry or passenger aircraft.

  • a taxi may carry from one to four passengers, while a passenger aircraft may carry anywhere from a few passengers to several hundred passengers.
  • the vehicle comprises one seat for every passenger carried.
  • the vehicle may also carry standing passengers, for example in the case of a train carriage.
  • the vehicle preferably comprises a number of first couplings, which at least corresponds to the maximal number of passengers, which may be carried by the vehicle.
  • airborne pathogens is understood as encompassing any bacteria, spore, virus or parasitic microorganisms, which may be spread from human to human by aerosols. This includes influenza viruses, coronaviruses, rhinoviruses, adenoviruses, human parainfluenza viruses, mycobacteria, streptococci and enterococci.
  • the seats of the vehicle are preferably arranged in rows within the cabin of the vehicle.
  • the rows may comprise any suitable number of seats, especially from one to ten seats per row.
