Definitions

  • the invention relates to a dental treatment chair, on the back of which is supported by means of a support member a headrest which is displaceable in the longitudinal axis of the backrest, which can be adjusted in various inclination positions by means of an adjusting device about a horizontal transverse axis, locked in these positions, and unlocked again by means of a trigger element which can be actuated by hand is.
  • a headrest for a dental treatment chair in which two mutually engaging by spring force, and disengageable by pressing a button toothed coupling members are available, one of which with the headrest housing and the other with the backrest or the support member is connected.
  • a disadvantage of such a construction is that when the headrest is loaded, ie when a patient is in the chair and the head rests on the headrest, the device is relatively difficult to unlock.
  • Unlocking the device can only be facilitated by relieving the headrest.
  • the headrest requires two-hand operation; the release link must be operated with one hand and the headrest must be held against tipping over with the other hand.
  • Another disadvantage is that only a stepped, so no stepless adjustment of the headrest is possible through the teeth.
  • the object of the present invention is to provide a treatment chair with a headrest adjustment which is improved in comparison therewith, which enables stepless adjustment in one-hand operation even in a loaded condition without great effort on the part of the operator.
  • the support member has at its end receiving the transverse axis a lever arm forming attachment to which a rod that can be subjected to tension and pressure is articulated, and that in the headrest housing is motorized driven, by means of the trigger member on and off, with self-locking and connected to the push and pull rod adjustment means are arranged.
  • an electric motor as the adjusting means, which drives a spindle arranged in the headrest housing, on which a spindle nut is placed, which is connected to the pull and push rod via a lever.
  • FIG. 1 shows a dental treatment chair, on the backrest 1 of which a headrest 2 can be pulled out by means of a support member 3, i.e. is adjustable in the direction of arrow 4.
  • a support member 3 i.e. is adjustable in the direction of arrow 4.
  • the support member 3 is held in the backrest in a known manner by means of a suitable longitudinal guide.
  • Fig. 2 which shows a top view of the headrest 2 with the cushion cover removed, reveals the inner structure of the adjusting device, with which an adjustment of the headrest in different inclination positions in the direction of arrow 5 in Fig. 1 is made possible.
  • a spindle 7 is rotatably mounted, which is driven by a belt 8 by an electric motor 9 fastened there approximately in the middle of the housing.
  • a spindle nut 10 which, as can be seen from FIG. 3, is secured against rotation via a tongue and groove guide 11.
  • a rocker arm 12 is seated on the nut 10 and is pivotably mounted on the opposite longitudinal side of the headrest 2 by means of a bearing 13.
  • a pull rod 15 is mounted by means of a further bearing 14, which is articulated on an extension of the support member 3, designated 16.
  • Fig. 4 shows that the axle bearing 17 of the pull and push rod 15 on the attachment part 16 to the bearing axis 18, with which the headrest housing 6 is articulated on the support member 3, forms a lever arm a.
