The system can include an airbag positioned between a vehicle frame and a headliner, and a trim member positioned inboard of the frame. The system can also include a deployment ramp coupled to the frame and the trim member. The deployment ramp can have a ramp surface. The ramp surface can be positioned and configured such that when the airbag is deployed a portion of the airbag engages the ramp surface and the trim member to urge the trim member in an outboard direction toward the frame. | 03-21-2013 |

20100180592 | Turbocharger - A bearing housing of a rotor shaft support assembly of a turbocharger core mounts to and closes a forward end of a cavity that both receives and discharges exhaust gases of an internal combustion engine. A turbine rotor operatively coupled to a rotor shaft and a compressor rotor of an associated turbocharger rotor assembly rotates within a turbine rotor shroud portion of an associated turbine nozzle cartridge assembly, wherein the rotor shaft is rotationally supported by at least one bearing within the bearing housing. The turbine nozzle cartridge assembly provides for directing exhaust gases from the cavity through a peripheral inlet leading to a plurality of vanes between forward and aft walls, through the turbine rotor shroud portion, and then through a nozzle exhaust portion incorporating an external sealing surface on an aft portion thereof that cooperates with a sealing element where the exhaust gases are discharged from the cavity. | 07-22-2010 |
20120011845 | Internal Combustion Engine Cylinder Head With Integral Exhaust Runners And Turbocharger Housing - An internal combustion engine cylinder head is based upon a one-piece structure including a number of exhaust runners, an exhaust collector, and a turbocharger exhaust turbine housing, all formed as one-piece. | 01-19-2012 |
20130004291 | Turbomachine Fluid-Conduit Housing Coupling System and Method - A shroud portion of a fluid-conduit housing provides for concentrically shrouding a portion of bladed rotor operatively coupled to a rotor shaft rotationally supported by at least one bearing operatively coupled to the centerbody. An internal cylindrical surface at an end of the fluid-conduit housing mates with a corresponding external cylindrical surface on a corresponding side of the centerbody. The fluid-conduit housing is operatively coupled to the centerbody with a plurality of radial pins, wherein each radial pin slideably engages with at least one of a corresponding radial bore in the fluid-conduit housing or a corresponding radial bore in the centerbody so as to provide for substantially maintaining the concentricity of the shroud portion of the fluid-conduit housing relative to the bladed rotor regardless of a thermal expansion of the fluid-conduit housing relative to the centerbody. | 01-03-2013 |
20130219884 | Internal Combustion Engine Cylinder Head With Integral Exhaust Runners And Turbocharger Housing - An internal combustion engine cylinder head is based upon a one-piece structure including a number of exhaust runners, an exhaust collector, and a turbocharger exhaust turbine housing, all formed as one-piece. | 08-29-2013 |
20140366526 | TURBOCHARGER COMPRESSOR ROTOR ALIGNMENT SYSTEM - An aftwardly-extending internally-threaded boss of a boreless-hub compressor rotor of a turbocharger engages a corresponding externally-threaded forward end portion of an associated rotor shaft of the turbocharger, wherein an internal surface of an inner race of an associated rolling-element bearing of the turbocharger is in engagement with both an external surface of the rotor shaft and an external surface of the internally-threaded boss of the boreless-hub compressor rotor, wherein the rotor shaft extends through the inner race of the rolling-element bearing. | 12-18-2014 |
