Abstract
A load limiting seat restraint retractor for a seat restraint system in a vehicle includes a housing for operative connection to vehicle structure. The load limiting seat restraint retractor also includes a take-up spool operatively connected to the housing and connected to webbing of a seat restraint system for winding and unwinding the webbing. The load limiting seat restraint retractor also includes a rotatable torsion bar operatively connected to the housing to provide a constant load limiting on the webbing during an impact. The take-up spool is mounted on the torsion bar. The load limiting seat restraint retractor includes a locking mechanism operatively connected to the torsion bar and the housing. The load limiting seat restraint retractor further includes a load limiting device disposed between the locking mechanism and the take-up spool to deform the take-up spool to provide digressive load limiting on the webbing during the impact.
