Abstract: The present invention relates to a power transmission that is interposed between the internal combustion engine and the drive ratio selection transmission of a vehicle. A motor/generator is operatively connected to the power transmission, and the power transmission selectively drives accessories to the internal combustion engine, such as an oil pump, power steering pump and air conditioning compressor. The power transmission employs compounded first and second planetary gear sets. A common gear member serves not only as the ring gear for the first planetary gear set but also as the sun gear for the second planetary gear set. The motor/generator drives the accessories when the internal combustion engine is idling or off, allowing those accessories to be smaller while delivering adequate output.
Abstract: A seat back for a motor vehicle having a tower extending upwardly from the seat back upper end along one lateral side of the seat back. The tower contains an inflatable air bag which is deployable to provide head side impact protection for a seat occupant. By mounting the air bag within a raised tower, the air bag is deployed from a higher location in the seat back to reduce the possibility of interference between the air bag and a shoulder belt. Furthermore, by not mounting the air bag to the seat back head restraint, it is possible to provide a fully adjustable head restraint attached to the seat back and extending upwardly from the seat back upper end. A removable side bolster is also provided which covers the air bag canisters mounted to the seat back frame. Following deployment of an air bag, the bolster and air bag canister are removed and replaced with new components. This enables the seat assembly to be repaired without replacement of the entire seat assembly or seat back.

Abstract: A suspension system for an automobile includes a compound torsion bar arrangement. The compound arrangement has a first bar which acts as a sway bar and a second bar which provides an output torque opposite to that of an input torque. The two bars are arranged to operate together and to be attached to the same location of respective wheel support structures. Variation of the torsional characteristics of the two bars of the compound arrangement allows the roll stiffness to be varied while also varying the forces which tend to lift the inside wheel when the automobile is moving in a curved path.

Abstract: The advantage of the theoretically correct Ackerman steering of land vehicles is well documented in the literature. Steering forces, vehicle handling, and tire wear are greatly improved by having correct toe angles of all steerable wheels. Adjustements in the suspension system and steering apparatus at the factory only provide first-order corrections to toe angles. A process for actively adjusting toe angles during operation of the vehicle is disclosed in this invention. Vehicle dynamics measuring devices to sense vehicle motion or position steering devices to measure toe angles are used in this process. Secondary toe angle corrections can be actively provided to account for inherent toe angle changes during maneuvers of the vehicle. An aftermarket apparatus for actively adjusting the toe angle is an embodiment of this invention.
Abstract: A hydropneumatic vehicle suspension system has a cylinder with an accumulator and a damper at each wheel. There is a supplementary hydropneumatic accumulator for each axle of the vehicle and first and second supplementary dampers connected respectively between the cylinders of the wheels of an axle and the supplementary accumulator. A valve is provided for selectively switching the supplementary accumulators into and out of communication with the cylinders of the corresponding axles. Each supplementary damper has a selectively actuable throttle for varying its damping. A soft suspension is obtained when the supplementary accumulators are switched in, a medium suspension is obtained when the throttles of the supplementary dampers are also actuated, and a firm suspension is obtained when the supplementary accumulators are switched out of the circuit.
