Abstract (en)
[origin: US4505514A] A dental chair having a support frame, a seat with a seat frame, a back rest pivotally connected to the seat and a displacement device for moving the seat frame on the support frame with tilting of the seat and an arrangement for controlling the inclination of the back rest, characterized by the pivotal connection between the seat comprising a separate pivoting bearing on each side having a pivot axis approximately in the area of the hip joint of a person sitting in the chair and the arrangement for controlling the inclination of the back rest comprising a one-piece member having two lever arms being pivotally connected on the side of the seat frame with one of the lever arms having a roller riding on the track on the support frame and the other lever arm being connected to a projection of a part of the pivoting bearing which is attached to the seat rest so that as the seat frame is moved between positions, the roller moving on the track enables the back to change its degree of inclination to the seat. The chair also includes an arrangement for tilting the seat which includes at least one pair of guide members which are inclined to each other by approximately 160 DEG and are mounted in the seat frame, which guide members receive sleeves that are pivotally connected to the support frame.
