Abstract

1475126 Reclining chairs ROYAL DEVELOPMENT CO Inc 24 May 1974 [29 May 1973] 23219/74 Heading A4J A recliner chair comprises a linkage mechanism which allows adjustment by the occupant from an upright position to a reclining position via an intermediate position. A headrest is formed by an upper portion of a secondary backrest and stowed behind the primary backrest in the upright position. The headrest, a footrest and a legrest are extended in the intermediate and reclining positions. The linkage mechanism is so arranged that the secondary backrest is raised to provide the headrest by the relative approach of pivots 94, 82, Fig. 3, the former connecting seat frame link 36 to a crank 80 whilst the latter connects a backrest link 50 to a U-shaped lever 76. In the intermediate position of the chair, Fig. 4 (not shown), the pivot 94 and a pivot 61 are almost concentric. The footrest 18a is extended on a lazy tongs type linkage operated by an extension of a front link 38. A legrest 18b, Figs. 4 and 5 (not shown), is supported on the rearmost end of link 150 and is pivoted to lie coplanar with the extended footrest by link 154.
