  • the headrest compensates, taking into account the anatomical shape of the body to be treated, the positional difference between the back surface and the head surface of the patient.
  • This head restraint positions should be achievable, which take into account both the anatomical shape of the body to be treated and the type of treatment.
  • the type of treatment namely a specific head position of the patient and thus also an adapted position of the headrest is desired.
  • the invention has the object to improve a dental chair of the type specified with respect to the adjustability of the headrest.
  • the headrest should fulfill at least one additional support function.
  • the headrest is alternatively adjustable in positions in which it is aligned on the one hand with the backrest cushion and on the other forms an obtuse angle.
  • This allows at least one additional support function, namely an extension of the backrest cushion.
  • the adjustment of the headrest is not only extended, but the headrest allows in its aligned position, the treatment in special settings, resulting in particular in a dental chair due to the cramped and varied treatment in the oral cavity of the patient to obtain a favorable position of the oral cavity , This applies both to the treatment of adults and children.
  • the headrest allows in its aligned position an advantageous child position, which is particularly well suited for children, especially when the headrest is pushed in its aligned position to the back, is preferably inserted into a recess on the headrest facing the end of the back part.
  • This configuration makes it possible to adjust the headrest in positions in which their head support surface not only has different heights and thus suitable for particular head positions, but the headrest is also suitable in the position in which a transverse bead of the headrest facing the back End of the headrest is arranged as a neck support, whereby the patient's head receives an additional and improved support.
  • the headrest or at least its upholstery, rotated with respect to this position by 180 °, this is advantageously suitable for children, in particular in the above-described child position.
  • An adjustment of the headrest can be realized in a simple and easy to handle manner in that the headrest or at least their pad is releasably connected by a quick-release connection, in particular in the form of a clamping device or latching device. This makes it possible to solve the headrest or at least her cushion for their adjustment and to assemble in another position.
