1. A downstop slide element having an overall width that automatically adjusts to compensate for dimensional variations between relatively movable parts of a seat suspension due to manufacturing tolerance and wear comprising:

  • first and second leaf members having spaced apart first and second top and bottom walls, front and rear walls, and inner and outer walls, respectively;

    connecting means interconnecting said leaf members to place said first and second inner walls in opposed confronting relation for movement toward and away from each other to form a longitudinally extending gap therebetween of variable width;

    a first biasing means for normally urging said pair of leaf members apart;

    a first tapered portion on said inner wall of at least one of said leaf members;

    a cam surface on said front wall of at least one of said leaf members;

    a width adjuster means positioned in said gap between said confronting walls and including a second tapered portion in face-to-face sliding engagement with said first tapered portion and a cam follower means in contact with said front wall cam surface; and

    a second biasing means normally biasing said width adjuster to move said first and second tapered portions relative to each other in a direction to cause said gap to widen and increase the overall width of said downstop slide element as required to compensate for dimensional differences between said parts due to tolerances and wear.
