Height adjuster for D-ring

An apparatus for adjusting the position of a seat belt webbing guide, said apparatus comprising:

• a movable slider having connector means for connecting said slider with the webbing guide to move the webbing guide with said slider;
• means for defining a track and for supporting said slider for movement along said track, said track having first and second ends;
• a first rotatable member;
• a second rotatable member;
• means for supporting said rotatable members for rotation;
• elongate flexible driving means for pulling said slider along said track, said driving means extending around and between said rotatable members so as to move longitudinally between said rotatable members upon rotation of said rotatable members;
• a first length of said driving means being connected with said slider and extending longitudinally from said slider toward said first rotatable member in a first longitudinal direction along said track, said first length of said driving means further extending around said first rotatable member to pull said slider toward said first rotatable member in said first longitudinal direction upon rotation of said first rotatable member;
• a second length of said driving means being connected with said slider and extending longitudinally from said slider toward said second rotatable member in a second longitudinal direction along said track opposite to said first longitudinal direction, said second length of said driving means further extending around said second rotatable member to pull said slider toward said second rotatable member in said second longitudinal direction upon rotation of said second rotatable member;
• and
• operator means for rotating said rotatable members to move said slider along said track when said operator means is actuated, said operator means being selectively actuatable by a vehicle occupant to rotate said rotatable members so as to move said slider a selected amount in each of said first and second longitudinal directions and thereby to move said slider into any selected one of a plurality of locations between said ends of said track.
