Abstract

Abstract 1,168,927. Seats. HALLAM, SLEIGH & CHESTON Ltd. 1 Aug., 1968 [23 Aug., 1967], No. 38720/67. Heading A4J. In a vehicle seat, a pair of thigh supports 1 are independently vertically movable against spring action. The thigh supports may be L-shaped in plan, extending along the front of the seat at 2, or alternatively, they may be forwardly extending portions (104, Fig. 8, not shown), of the seating surface (103). Each support 1 is mounted on a pivoted link 15 so that, when the user exerts downward pressure on the support, the link 15 turns in a clockwise direction, about its lower pivot and slide 8 is' moved rearwardly, through its pivotal connection 12, away from rubber buffer 14, of adjustable stop 13. The force of return tension spring 27 is adjustable, by means of a knob (24, Figs. 4 and 6, not shown) and the position of stop 13, by knob 31. On relieving the support 1 of the downward pressure, spring 27 becomes effective to raise it, until slide 8 abuts buffer 14.
