    Abstract: THE FOLLOWING SPECIFICATION DESCRIBES A CHAIR CONTROL UTILIZING AN ANNULAR RUBBER SPRING BONDED AT ITS EXTERNAL SURFACE TO A SHELL HELD BY THE POST HORN AND BONDED AT ITS INTERNAL SURFACE TO A TUBE, WHICH IS LONGITUDINALLY DISPLACED IN RESPONSE TO RATIONAL MOVEMENT OF THE OCCUPANT SUPPORT MEMBER. A CHAIR CONTROL IS ALSO DESCRIBED IN WHICH FORCES CREATED IN RESPONSE TO PIVOTING MOVEMENT

    OF THE CHAIR OCCUPANT ARE APPLIED IN A DIRECTION CORRESPONDING TO THE POST AXIS AND ARE RESISTED BY A SPRING ARRANGED ALONG THAT AXIS.

    Abstract: 1,161,464. Seats. STEWART-WARNER CORP. 29 Dec., 1967 [30 Dec., 1966], No. 59130/67. Headings A4J and A4U. In a tilting chair, a back-rest rotates about the axis of a torsion bar 38, which opposes its rearward pivoting motion, while a seat participates in this motion to a reduced extent, by turning about its front pivotal connections 90, by which it is mounted on a stationary support body 22. The ends of bar 38 are secured in extensions 32, 34 of the support body, which has integral side walls 24, 26. The backrest, which is adjustably clamped in angularly adjustable shoe 64, turns plates 44 about bearings 42, carried on bar 38 and applies a moment to the bar 38, by means of screw 50 engaging arm 48, fast with the bar. The rotation of plates 44 is transmitted to the rear of the seat by toggle linkage 56 connected to seat fastenings 84. In another form, pivots 90 are replaced by a torsion bar (100, Figs. 8 and 9, not shown).
