  • a strap is adjustably arranged on the second connecting part.
  • connection device In a connection device of the type mentioned, it is generally desirable to enable the connection parts to be connected in a simple, comfortable and haptically pleasant manner for a user.
  • the connection should preferably be made possible in a position-tolerant manner, with imprecise attachment of the connecting parts to one another. In When the connecting parts are in a connected position, a secure, resilient connection should be created.

  • the first connecting part has a first magnetic device and the second connecting part has a second magnetic device.
  • the first magnetic device and the second magnetic device interact in a magnetically attractive manner and in particular also support the attachment of the connecting parts to one another.
  • the magnetic devices have a magnetically attractive effect along the closing direction, so that the magnetic devices cause a magnetic attraction force along the closing direction and pull the connecting parts towards one another along the closing direction when they are attached.
  • the magnet devices can each be formed by a permanent magnet, for example. However, it is also possible to design one of the magnet devices with a permanent magnet and the other of the magnet devices with a magnetic armature and thus with a passive-magnetic element.
  • connecting parts Due to the rotational mobility about the closing direction, a position-tolerant attachment of the connecting parts to one another is possible, in that it is not necessary to attach the connecting parts to one another in an exactly defined rotational position.

  • the belt arranged on the second connection part (fixed or adjustable) can thus be moved over the at least one engagement projection on the first connection part - with or without touching the engagement projection - when the connection parts are in the connected position and are rotated relative to one another.
  • the belt can thus, for example, slide onto the at least one engagement projection and be moved over the engagement projection on the side facing away from the floor surface, so that the engagement of the engagement projection of the first connection part with the engagement section of the second connection part does not impede the mobility of the connection parts relative to one another.

  • the belt can thus be moved relative to the at least one engagement projection and thus extends over the engagement projection or not, depending on the rotational position.
  • the strap should extend beyond the at least one engagement projection, this means that the strap extends approximately radially away from the second connecting part in the intended manner, starting from the second connecting part, and the section starting from the second connecting part of the strap extends beyond the at least one engagement projection.

  • the belt can thus be moved freely toward the base body radially outside of the fastening section. This allows the webbing to slide over the engagement portion with the at least one engagement projection to move away the engagement projection without thereby impeding the engagement of the engagement portion with the at least one engagement projection.
  • the exit point is spaced radially from an axis of rotation directed along the closing direction, about which axis of rotation the second connecting part can be rotated relative to the first connecting part in the connected position.

  • the exit point in the case of a linear (straight line or curved) extension, can be arranged completely or only partially radially outside the engagement section.
  • the spacing from the axis of rotation can in particular ensure that loading forces introduced into the second connecting part via the belt do not lead to an (unintended) tilting of the second connecting part relative to the first connecting part and thus the connecting parts are safe and reliable in the connected position even under load are held together.
