Abstract
A dampening device is provided for a seat retractor associated with a passive seat belt system to reduce the rewind speed of the webbing in response to closing of a door of the vehicle. The dampening device is inoperable when the door is opened. The seat belt webbing may be maintained in a non-restraining position and automatically released to its restraining position under a slow rewind speed in response to a condition indicating that the vehicle is operable for locomotion. The dampening device may alternatively be actuated in response to a condition indicating that the vehicle is operable for locomotion.
