Definitions

  • the invention relates to a medical or dental treatment chair or to a headrest for such a treatment chair according to the preamble of claim 1 and 2, respectively.
  • a dental chair or a headrest of these types are in the DE 296 20 801 U1 described.
  • a pivoting device in the form of a four-bar linkage, wherein an associated locking device for detecting the pivoting device in the respective pivot position is also present.
  • the locking device has a coupling in the region of the base joint of the four-bar linkage, with a movable between a coupling position and a uncoupling coupling element for selectively locking or releasing the joint.
  • a manually movable actuator for opening and / or closing the clutch is provided, which is connected by a cable to the clutch.
  • the coupling is associated with a locking device with a locking part, which blocks opening of the clutch when the actuator is unactuated and releases when actuated actuator.
  • the pivoting device has a handlebar with two joints in its end regions, which carries the headrest through its base joint with a headrest holder of an associated backrest and in its second joint.
  • the joints is associated with a locking device with a pneumatic piston cylinder with a working chamber for clamping the joints.
  • the piston cylinder can be acted upon and activated by the pneumatic pressure of a hand pump.
  • For a clamping of the joints it requires a considerable clamping voltage, since in functional operation, the headrest is subject to considerable loads that can be exercised mainly by the patient on them and they are looking to adjust.
  • Another disadvantage of this known embodiment is that it requires a complex handling to the headrest in the to set the desired position. For this purpose, both operating hands are necessarily required, with the one hand, the headrest to adjust and position and with the other operating hand, the pneumatic pressure member is to press.
  • a treatment chair or a headrest of the types mentioned above is also in the EP 0 673 633 A2 described.

  • the actuator is a tiltable mounted part in this known embodiment, which is tiltable with the operating hand.
  • the actuator is connected by a cable to the clutch, so that the tilting movement can be exploited to open the clutch.
  • the invention is based, to improve the support function in a dental chair or a headrest of the types specified in the task. It should be low manufacturing costs and / or handling effort for adjusting and adjusting the headrest. In addition, the headrest should be stable in its adjusted position, so that the risk of unintentional adjustment is avoided or reduced.

This measure can be carried out with little effort, in particular force, and with a small movement, so that the opening and closing of the valve is easy to handle feasible.
  • Piston cylinders of this type are in themselves known components that are available in the technical market and have been used for other purposes.
