Abstract: A power steering apparatus includes a housing defining a chamber. A rack is disposed within the chamber and is moveable along a longitudinal axis. A pinion extends into the chamber for meshing engagement with the rack. A bearing supports the rack relative to the housing and is moveable relative to the housing to re-position the rack relative to the pinion.

A dampener resists the movement of the bearing to slow the re-positioning of the bearing. Preferably, the dampener includes a plastic fluid having a very high viscosity. The plastic fluid is disposed between adjacent moving parts to resist the relative movement between the bearing and the housing.

The spring retainer is rotated past the rotor until a predetermined spring preload is achieved. A retaining feature is installed through the arcuate slot into the rotor bore, thereby biasing the rotor in the predetermined bias position at the predetermined bias spring preload. In another embodiment, the spring retainer is a rotatable cam feature that becomes fixed to the stator after spring adjustment is complete.

Abstract: A seat belt retractor having first and second serially arranged torsion bars and a switching mechanism provides two levels of load limiting. A bridge bolt rotationally fixed to the inboard ends of the torsion bars is threaded into a locking base, and the switching mechanism prevents bridge bolt translation relative to the locking base in a default condition to limit seat belt load with the first torsion bar. Activation of the switching mechanism permits limited translation of the bridge bolt relative to the locking base to limit seat belt load with the second torsion bar. Additional translation of the bridge bolt relative to the locking base is prevented to re-establish load limiting with the first torsion bar. The switching mechanism includes a set of detent wedges, a retaining band and an electrically activated cutting mechanism, all disposed within the retractor frame.

Abstract: Impending rollover events are detected by recognizing a plow phase increase in lateral acceleration, coupled with a significant trip phase roll rate. The plow phase increase is recognized by modeling a typical soil trip lateral acceleration characteristic and computing a cross-correlation between the measured lateral acceleration and the modeled acceleration. The correlation is compared to a threshold that varies with the measured roll rate to reliably discriminate rollover events from near-rollover events while enabling timely deployment of suitable occupant restraints.
