Definitions

  • the invention relates to a medical or dental medicine treatment chair with a headrest according to the preamble of claim 1.
  • a treatment chair of this type is e.g. B. described in DE 296 20 801 Ul.
  • the headrest is adjustable in positions in which it is suitable for safely supporting the head of the patient to be treated, so that trouble-free treatment is ensured.
  • the headrest compensates for the difference in position between the back surface and the head surface of the patient. It should be possible to achieve headrest positions that take into account both the anatomical shape of the body to be treated and the type of treatment. Depending on the type of treatment, a specific head position of the patient and thus an adapted position of the headrest is desirable.
  • the invention has for its object to improve a treatment chair of the type specified with respect to the adjustability of the headrest.
  • the headrest should perform at least one additional support function.
  • the headrest is alternatively adjustable in positions in which it is aligned with the backrest cushion on the one hand and encloses an obtuse angle on the other.
  • This enables at least one additional support function, namely an extension of the backrest cushion.
  • the adjustment range of the headrest is not only expanded, but the headrest in its aligned position enables treatment in special positions, which result in particular in a dental chair because of the narrow and varied treatment in the patient's mouth in order to maintain a favorable position of the mouth , This applies to the treatment of both adults and children.
  • the headrest in its aligned position enables an advantageous child position, which is particularly suitable for children, especially when the headrest is pushed towards the back part in its aligned position, is preferably inserted into a recess on the end of the back part facing the headrest.
  • This configuration makes it possible to adjust the headrest in positions in which its headrest surface not only has different heights and is therefore suitable for special head positions, but the headrest is also suitable in the position in which a cross bead of the headrest on the back part facing End of the headrest is arranged as a neck support, whereby the patient's head receives additional and improved support.
  • the headrest or at least its cushion which is rotated by 180 ° with respect to this position 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 user-friendly manner in that the headrest or at least its upholstery by a quick-action connection, in particular in the form of a clamping device or
  • Locking device is detachably connected. This makes it possible to loosen the headrest or at least its cushion for its adjustment and to mount it in a different position.
  • a manually pressable clamp or latching device is particularly well suited as a quick-connect connection, because such a configuration can be produced inexpensively and inexpensively and ensures secure mounting with quick and easy-to-use adjustment.
  • the setting device should enable simple, easy-to-use and targeted setting, taking into account the patient's anatomy, and it must also be taken into account that essential physical features, e.g. B. the body size, neck length and head shape, may be different.
  • the adjusting device should be of small and simple construction in order to be able to integrate it in the backrest / headrest area of the treatment chair in the simplest possible way. Furthermore, the manufacturing costs should also be low in order to improve the market opportunities.
  • the invention is further based on the object of a present
  • the embodiment according to claim 12 enables a simple and small design, which u. a. can advantageously be integrated into the rather flat cavity of a backrest and also enables a specific adjustment of the headrest, in particular its inclination.
  • the latter is already ensured in that a drive motor is provided for adjusting the headrest inclination, which only fulfills this function.
  • the drive motor for adjusting the headrest inclination can be operated simultaneously with a drive motor for adjusting the height of the headrest or its distance from the backrest or individually.
  • it is advantageous to choose the movements so that the resulting movement of the headrest is adapted to or approximates the anatomical head movements of the human body.
  • a sufficiently simple movement control of the headrest can be achieved if it is connected to the headrest support by a four-bar linkage or four-link mechanism. Such a transmission can also be adjusted in a simple manner in a targeted manner by a drive integrated in the backrest and thus clad by the backrest and positioned in the desired adjustment positions. It is an important task for a dental chair operator to pay attention to the patient's treatment. This applies both to the treating operator and to an operator as an assistant. The operating measures for the dental chair should therefore affect the operator's attention as little as possible.
  • the invention is furthermore based on the object of finding a switching device for carrying out switching operations on medical or dental medical devices, in particular for the treatment chair, which enables the switching operations to be carried out in a simple and user-friendly manner.
  • a switching topography is assigned to the switching device with respect to one or more actuating surfaces of an associated switching element.
  • This configuration according to the invention is also distinguished by a particularly simple configuration which leads to significant advantages with simple measures. If the guide topography is formed by a guide groove in the base surface from which the switching element protrudes, not only is there good guidance, but also an at least partially recessed arrangement of the switching element, so that there is largely an incorrect actuation during other movements of the operating hand is withdrawn. Therefore, the configuration according to the invention also leads to an improvement in the operational safety of the treatment chair.
