A selectable load limiting seat restraint retractor for a seat restraint system in a vehicle includes a take-up spool connected to webbing of a seat restraint system for winding and unwinding the webbing. The selectable load limiting seat restraint retractor further includes a rotatable first torsion bar to provide a first level of load limiting on the webbing during an impact. The selectable load limiting seat restraint retractor includes a rotatable second torsion bar orientated parallel to the first torsion bar to provide a second level of load limiting on the webbing during an impact. The second level of load limiting is less than the first level of load limiting. The selectable load limiting seat restraint retractor further includes a selectable load limiting mechanism cooperating with the first torsion bar and the second torsion bar to select between the first level of load limiting and the second level of load limiting to provide digressive load limiting on the webbing during an impact.
