  • the chin part is brought into contact with the upper shell.
  • the joint ends of the chin part meet the upper shell.
  • In the articulated ends of the upper shell there are steel bolts or metal bolts, or bolts made of another material, in particular with magnetic or magnetizable parts, which correspond and interact with magnets inserted in the articulated ends of the chin part.
  • the surface itself is designed like a large joint socket.
  • the offset to the inwardly offset surface, which will later enter the upper shell is in the form of a quarter circle.
  • the large diameter of the turning circle section also makes it much easier to find the area.
  • the spring of the chin part which is designed to interact with the groove, engages at the point at which the joint end is already in the funnel-shaped groove in the foam body the upper shell is located. Due to the lack of upholstery contact, this is still completely force / tension free.
  • the surfaces of the upper shell and the chin part at the point or at the point of the articulation axis still have very different surface orientations due to their rotated position relative to one another.
  • the surfaces are crooked.
  • the screwing in follows.
  • the padding in the chin section collides with the wearer's face for the first time and is compressed when it is screwed in further. Since the U-shaped chin part as an individual part is already gripped by the groove of the outer shell at the joint ends, and is thus connected to the rest of the helmet, this cannot spread out due to the force of the cushion restoring forces.
  • the alignments or the surfaces continue to adjust until a continuous volume is created in the closed state and the surface slopes at the parting line are aligned identically, at least almost identically.
  • the spring at the fulcrum approaches the outer shell from the inside as it is screwed in. In this way, the bolt inserted in the joint end of the upper shell continues to move into the hole in the joint end of the chin part until the shells contact.
  • the tongue of the chin part continuously shears into the circumferential groove of the upper shell. Accordingly, the restoring force of the cushion is always counteracted as close as possible to the point at which the force is applied.
  • the groove is designed funnel-shaped all around in order to also be able to catch a spring section which approaches in an offset manner.
  • the inclination of the tongue and groove shear surfaces improves the sliding properties when retracting. The remaining attachment via the fasteners is described so far.
  • a magnet is provided for a better initial finding of the swivel joint. With the help of the magnet on the swivel joint and the joint head-in-joint socket-like outer shell shape of the upper shell and chin part, the initial finding in a quarter circle on the swivel joint is easy.
