Abstract

391,954. Seat adjustments. WHITE, W. W., 39, Springfield Park Road, Burnside, Rutherglen, Lanarkshire. March 14, 1932, No. 7480. [Class 52 (ii).] A vertically adjustable non-rotatable seat is provided with recessed portions at the front to allow the thighs of the sitter to be inclined downwards. The armchair comprises a fixed seat 12 and frame 11 with arm and back rests 14, 13 and a movable seat 15. Both the fixed and movable seats are recessed as at A or B. The vertical adjustment of the seat 15 is obtained by means of a screw-threaded spindle 16 secured to the underpart of the seat and moved by a rotatable nut 17 which is operated through the sprocket wheels and chain by a handle 25 on the arm rest 14 of the chair. The sprocket wheels and spindle are enclosed in casings filled with lubricating oil. The movable seat bottom 15 is guided on metal strips 27 secured to pillars 26 supporting the arm rests. In the modification shown in Fig. 4, the adjusting means comprises a rack 34 and pinion 37 and the pinion is driven through bevel gearing and a clutch (not shown). A brake is also incorporated and becomes operative when the clutch is released and prevents the seat dropping too quickly. The bottom of the rack 34 is formed as a piston 64 and it gives a braking effect by its movement in the air cylinder 65. In another modification, the seat is raised by cables wound on a drum and the driving mechanism may be an electric motor.
