Definitions

  • the linkage mechanism is one of a pair thereof, one being located at each side ofthe chair between the supporting framework and the respective adjacent sides of seat and backrest.
  • Primary control link 96 is pivoted at 98 at its forward end to a minor legrest plate 100 which functions as a support for minor legrest portion 54.
  • Wing nut 134 may be tightened against washer 136 wherefore friction finger 130 is drawn inwardly to increase the frictional engagement between friction plate 120 and rise bar 64, and conversely, by loosening wing nut 134, the frictional engagement between friction plate 120 and rise bar 64 may be decreased, the whole functioning as an adjustable braking system whereby the force or weight required to move both the seat and backrest to one of a plurality of reclining positions may be varied, in accordance with the dictates of the chair occupant.
  • Upper backrest part 16 is operatively connected by means now to be described to the body-supporting unit, to the supporting framework and to the legrest for movement between a retracted position when the chair is upright and a position overlying the lower backrest part 15 when the chair is reclined, upper backrest part 16 and legrest 50 reaching their respective extended positions simultaneously.
  • seat link 180 In the course of movement from upright position to a reclining position wherein upper backrest part 16 is extended, seat link 180 is rotated in a clockwise direction, as viewed in the drawings, by chassis link 182, the seat link in turn urging first connecting link 166 to pivot in a clockwise direction, thereby to urge the support plate 152 to move rearwardly and upwardly, swinging by means of pivot links 154 and relative to L-link 32.
  • the support plate 152 Upon movement of the chair from the intermediate position to the upright position, the support plate 152 is swung downwardly in the reverse direction to return the upper backrest part to a retracted position within the lower backrest part.
