Abstract: An air bag module which includes a panel member having an integral reaction canister having a plurality of reaction walls and a manifold assembly having a manifold. The manifold includes at least one deployment door retaining channel and is operable for retaining an air bag cushion, an inflator, and a deployment door. The deployment door includes at least one retaining bead and a trim portion which are separated by a pliant spacing leg. As the reaction canister is incorporated into the panel member, the need for a separate reaction canister component is eliminated, thereby reducing cost, weight and overall size of the air bag module and allowing the manifold assembly to be used across a wider range of vehicles. The retaining bead and spacing leg flexibly couple the cover door to the manifold and allow the cover door to be repositioned during installation of the manifold assembly into the panel member so as to eliminate gaps, puckering and other defects in the appearance or the vehicle interior.

Abstract: An in-line combination steering pump with a shaft and water pump having a housing defining a pumping chamber into which the outer end of the shaft extends. The water pump housing supports an annular adapter member for supporting a seal which encompasses the shaft and is press mounted in the adapter. An impeller is removably secured to the outer end of the shaft adjacent the seal. A bushing encompasses the shaft between the seal and the impeller and is compressed by attachment of the impeller to the shaft so as press the seal firmly into the adapter. For replacement, the seal and bushing are removable over the outer end of the shaft after the impeller is removed.

Abstract: A method is provided for determining the rationality of a device for monitoring the pressure within an evaporative emission control system of an automotive vehicle. The method includes opening a valve of the evaporative emission control system and determining if a vacuum switch of the evaporative emission control system opened. If the vacuum switch opened, a code is set indicating that the vacuum switch passed an opening test. If the vacuum switch did not open, the method determines if a fail timer is greater than a first fail threshold value. The first fail threshold value corresponds to an amount of time within which a properly functioning vacuum switch should open after said valve is opened. If the fail timer is greater than the fail threshold value, the method sets a code indicating that the vacuum switch failed the opening test. If the fail timer is less than or equal to the first fail threshold value, the method increments the fail timer.

Abstract: A vehicle steering assembly includes a mounting bracket for the steering column, such that during a crash situation friction surfaces on the steering column slides through an opening in a plastic block carried by the mounting bracket. The friction surfaces have an interference fit with the opening in the plastic block, so that during normal operation of the vehicle the steering column is effectively locked to the mounting bracket.
