  • a stop pin 125 located on the front end of finger extension 59, and it is contacted by the primary lifter link in the closed position of the linkage as seen in FIG. 5.
  • the pivot pin 105 is located at the lower end of slot 104, in sequence link 101, and prevents the chair from moving into fully reclined position because the primary lifter link 85 is pivoted, as at 93, to the bellcrank and the bellcrank is pivoted, as at 100, to the sequence link.
  • the leg-rest or ottoman-supporting links must first be projected.
  • the pivot pin being at the lower end of slot 104, an upward movement of the mechanism or linkage is prevented because the lower end 102 of the slotted sequence link is a rigid strut which prevents movement of the bellcrank 90.
  • the opposite end of the slot provides the final stop in fully reclined position, as seen in FIG. 7.
  • the sequence link thus has two purposes.
  • the ottoman-supporting bracket and guard (120, a) go completely under the chair.
  • the movement of the ottoman mounting brackets is delayed until the seat has reached the maximum upward position (as distinguished from backward movement).
  • the seat moves upwardly and rearwardly from closed position as the linkage moves from the closed position of FIG. 5 to the TV position of FIG. 6.
  • the bracket 120 moves slowly (stays almost horizontal) until the scat-mounting link has reached its maximum upward motion. By that time, the ottoman bracket 120 has reached its lowest limit relative to the floor. This bracket 120 first moves slowly and then faster. Pivots 111a, 111a and 123 are almost in a straight line in the closed position of FIG. 5. As a result of the angular displacement of these three points, relative to pivot 119, is a small vertical displacement for a given angle, and then a larger vertical displacement for a continued movement of same angular extent.
  • the bellcrank 90 pivots about pivot 93 to move the seat-mounting link 70 vertically and horizontally to change its angle by means of the rear carrier link 67.
  • the seat-mounting link 70 is rotated clockwise, looking at FIGS. 5 and 6, so that its rear end moves down.
  • the chair back maintains its position relative to the seat mounting link by means of the rear control link 81a, but moves down relative to the floor, thereby increasing the seat pitch or the incline of the seat relative to the floor.
  • the lifting of the front of the seat is simultaneously caused by the secondary lifter link 65 acting through pivot 0% on primary lifter link 85 which is pivoted to the bellcrank 90 at pivot 93.
  • This bellcrank 90 is connected to the seat-mounting link 70 at pivot point 89.
