SEAT BELT RETRACTOR WITH TENSION ELIMINATOR

摘要

A seat belt retractor with a tension eliminator is provided with a ratchet wheel arrangement which acts as a position memory upon closing of a buckle switch and which is responsive to the belt webbing being drawn off the reel of the retractor by a seat occupant leaning forward beyond a predetermined distance, the wheel being rotated via an internal/planetary gear arrangement, proportionally to the excess distance whereupon the webbing can be retracted only said predetermined distance inducing a degree of tension eliminating slack in the webbing upon return of the occupant to the position in which he or she buckles the seat belt.
