Abstract
A spool for a vehicle safety restraint has a cylindrical central spool member made of two separate pieces. The cylindrical portion has a hollow section along its axis for accommodating seat belt webbing and a torsion bar, with a seat belt webbing entrance slot and a seat belt webbing exit slot. A filler plate is shaped to fit snugly into the entrance slot and to hold the parts of the spool assembly including the torsion bar and the spool against movement thereby holding the spool together.
