Abstract
1,121,592. Dental chairs. A. G. SVARD. 24 Jan., 1966 [25 Jan., 1965], No. 3057/66. Heading A4J. In a dentist's chair, a linkage 12, 14 and 20, having fixed pivots 18 and 24, is arranged to increase the angle V, V1 between thigh and shank supports 12 and 14, on moving them from the sitting to the reclining position. The motion may be effected by a hydraulic cylinder (60). The length of link 20 may be varied by hydraulic means or, alternatively, the distance between the ends of a two-part articulated link may be varied by altering the included angle. The back rest may be independently or simultaneously lowered by hydraulic cylinder (54). The back rest includes an angularly adjustable head rest (44) and is divided into two mutually extensible sections 30, 32. Hydraulic cylinder (50) moves section 30 relatively to section 32. Fore-arm rests (42) are provided for the occupant and hand rest (46) for the dentist. The adjustments may alternatively be effected by manually operated screw and nut means.
