Said differently, the frame axis 186 is nearer to the mount axis 172 when the tilt members 152, 154 are in the collapsed configuration than when the tilt members 152, 154 are in the expanded configuration.
  • the tilt actuator 194 controls the relative position of the first tilt member 152 and the second tilt member 154. Movement of the tilt actuator 194 from the retracted position to the extended position moves the tilt members 152, 154 from the collapsed configuration to the expanded configuration. Likewise, movement of the tilt actuator 194 from the extended position to the retracted position moves the tilt members 152, 154 from the expanded configuration to the collapsed configuration.

  • the height adjustment motor 144 has been operated to pivot the rear links 132, 134 in a clockwise direction and move the height actuator 130 to increase the distance between the seat cushion 102 and the track assembly 112 relative to the lowered position.
  • the intermediate height and the raised height are exemplary positions of the seat cushion 102 and are not intended to be limiting or to define discrete positions of the height actuator 130 and the seat cushion 102.
  • the upright position and the ultra comfort position are not intended to be limiting and the cushion tilt module 150 may be operated so as to place the seat cushion 102 in an intermediate position (not shown) between the upright position and the ultra comfort position illustrated herein.
