Abstract: A lift axle assembly for supporting an auxiliary axle and wheels and selectively moving the auxiliary axle between in use and storage positions. The auxiliary axle is supported using two sets of upper and lower support arms pivotally connected between saddles attached to the axle and support hangers which are attached to the vehicle. Lift air springs selectively push the upper support arms vertically upwardly for rotating the support arms and placing the auxiliary axle in the storage position. The pivotal connections of the lower support arm as well as the pivotal connection of the upper support arm to the support hanger are of a bushing type allowing both rotational motion about the axis of rotation and coning for allowing twisting of the support arms about their longitudinal axes.

Abstract: A steering wheel assembly has a mounting plate which secures a molded steering wheel to a steering shaft in a vehicle. The mounting plate has a pair of slots having respective longitudinal axes which intersect the plane of the steering wheel at a six o'clock position with an included angle of approximately ninety (90) degrees. The longitudinal axis of one of the slots intersects a transverse axis of the steering wheel at a forty-five (45) degree angle at a three o'clock position and the longitudinal axes of the other slot similarly intersects the transverse axis at the nine o'clock position. The slots are effective to control energy absorption and deflection of the steering wheel when it is impacted at a position other then the twelve o'clock position.

Abstract: An automotive golf caddy has a high frequency position finder and an ultrasonic position finder. When the caddy is placed in readiness by means of a manual transmitter, it first determines whether it receives ultrasonic signals from the manual transmitter. If that is not the case, it determines by high frequency position finding the direction of the manual transmitter and approaches the transmitter on a straight path at a relatively high speed. When the caddy enters the ultrasonic position finding range, it is automatically switched to ultrasonic position finding, follows the manual transmitter even in curves and continuously determines its distance from the transmitter. When a predetermined minimum distance is reached, the motors of the caddy are switched off. It will only follow the transmitter automatically once again when the transmitter reaches a predetermined distance from the caddy.

Abstract: A sensor designed and adapted to operate with vehicle restraints whose primary purpose is to sense low "g" accelerations and vehicle tilting, the results of which lead to the activation or deactivation of the primary occupant restraints through a control module. This invention specifically addresses the reliability of vehicle acceleration and tilt sensors. By employing fewer numbers of components and by having a fewer number of failure mechanisms this invention provides a sensor of increased reliability and lower manufacturing cost. Furthermore, this sensor invention restrains effect z-axis accelerations often encountered when a vehicle is merely traveling over rough roads. This invention employs innovative detector technology, alternatively using an IR detector or a Hall Effect Device detector.

Abstract: An actuatable inflator (10) for inflating an inflatable vehicle occupant protection device (12) includes a container (70) having a cup-shaped wall including a base portion (72) and a side wall portion (74). The container (70) is a one-piece structure. The base portion (72) and the side wall portion (74) at least partially define a combustion chamber (84) in the container (70). An ignitable material (110) in the combustion chamber (84), when ignited, rapidly increases the fluid pressure inside the combustion chamber. An electrically actuatable initiator (112) ignites the ignitable material (110). The base portion (72) of the cup-shaped wall includes a predefined rupture portion (90). The rupture portion (90) ruptures when the fluid pressure inside the combustion chamber (84) reaches a predetermined elevated fluid pressure level to form an orifice (120) through which the inflation fluid in the combustion chamber flows.
