Definitions

  • the invention relates to a medical or dental medicine Dental chair.
  • the upright support arm a so-called parallelogram support arm with two juxtaposed parallelogram arms, which in the sense of a Articulated quadrilateral with a support arm base part and a support arm head part are connected.
  • This known arm is in a right angle to the axes of the four-bar pivoting plane tiltable and thus in its inclination adjustable, as well as height adjustable.
  • an electrical Drive motor provided, which is integrated in the parallelogram support arm.
  • the upper end of the support arm leads to one A lateral curve movement because the simultaneous Adjustment of the inclination and height using the characteristics of the four-bar linkage is determined.
  • a height adjustment that is independent of the inclination setting not possible with this known configuration.
  • the latter is desirable order for the treating person a predeterminable removal position and a easy removal of the treatment tool at individual altitude To enable patients.
  • the document DE 32 30 248 A1 describes a medical or dental medical treatment chair with a storage device for at least one treatment tool, which is arranged in a lateral position with respect to the treatment chair on a substantially vertical support arm which is carried by a support which is horizontally adjustable, in particular is mounted on the treatment chair, the storage device being rotatably mounted relative to the support arm and / or the support arm relative to the carrier in each case about an approximately vertical joint axis of a joint, wherein the support arm is designed as a telescopic device and its length can be adjusted along its longitudinal axis by a height adjustment device and can be locked in the respective adjustment position by a locking device.
  • this known treatment chair is the Support arm designed in the sense of a telescopic device with two telescopic parts, which are adjustable relative to each other in the longitudinal direction of the central axis of the support arm and can be determined in the respective setting. Due to the straightforwardness of the Height adjustment movement can be a desired in this embodiment Predetermine height position more easily.
