Abstract: A process for determining lateral overturning of a vehicle involves establishing a threshold value line S separating a lateral overturning region farther from an origin and a lateral non-overturning region closer to the origin on a two-dimensional map made using a rolling angle &thgr; and a rolling angular speed &ohgr; of the vehicle. When a hysteresis line for actual rolling angles and actual rolling angular speeds of the vehicle traverses the threshold value line from the lateral non-overturning region to the lateral overturning region, it is determined that there is a possibility of lateral overturning of the vehicle, and correspondingly an occupant protecting system may be deployed. Also, to assure accuracy, a lateral acceleration sensor for detecting a lateral acceleration for establishing the threshold value line S is disposed on a center plane of a vehicle body.

Abstract: A seat belt retractor is provided with an energy management system that achieves a known, predictable dissipation of energy which allows the force load on the shoulder belt and an amount of belt protraction to be carefully controlled for a given vehicle's crash characteristics. At shoulder belt loads below the onset force level, the inertia or web-sensitive locks lock both the reel and reel shaft against rotation and belt protraction with no energy dissipation.

The extrusion die can be formed integrally on the reel shaft with the driver nut pushing the bushing axially onto the die section of the shaft to deform the bushing.
