US Patent 11339904 Magnetic hose coupling for helmet forced air hose

A magnetic hose coupling system for a helmet includes first and second coupling conduit segments magnetically coupled to each other. The first segment includes a hinged clamp at a first end to attach to a forced air intake barb on a motorsport helmet and an angled polygonal mating surface at a second end with magnetic attractors in the polygonal mating surface. The second segment includes an internally threaded first end to attach to a forced air hose and an angled polygonal mating surface at a second end with magnetic attractors in the polygonal mating surface. The polygonal mating surfaces of the first and second segments magnetically couple together and resist rotational and sheer movement of the first and second segments with respect to each other.
