Publication number: 20130192967Abstract: A steering wheel assembly comprises a plurality of control elements disposed on a user-accessible surface of the steering wheel assembly. Each of the plurality of control elements has a plurality of user-selectable operational states and is electrically coupled to a corresponding branch of an electric circuit. The electric circuit defines an output node and is configured to produce a single output signal at the output node. Each of the plurality of control elements is configured for affecting the single output signal based on an active one of the plurality of user-selectable operational states of the respective one of the plurality of control elements. The single output signal is indicative of the active ones of the plurality of user-selectable operational states for each of the plurality of control elements.Type: ApplicationFiled: January 25, 2013Publication date: August 1, 2013Applicant: Steering Solutions IP Holding CorporationInventors: Gerald M.

Patent number: 8033738Abstract: A bearing assembly is provided including at least one needle roller that is resiliently compressible in response to a load applied to an exterior surface thereof. In addition, a method is provided for taking up a clearance between one or more first rollers and a bearing race in which the rollers are positioned. At least one resiliently compressible second roller is provided rollably secured within the bearing. The compressible second roller has an outer diameter greater than an outer diameter of any of the first rollers, such that the compressible second roller resiliently compresses when the bearing is positioned in the bearing race. Forces generated by compression of the resiliently compressible second roller urge the first rollers against a surface of the bearing race, thereby taking up the clearance between the first rollers and the race.Type: GrantFiled: October 9, 2007Date of Patent: October 11, 2011Inventors: Richard P. Nash, Ravi Ravindra, Michael D. Smith

Patent number: 7913583Abstract: A transmission gear selector including a pivotal shift lever with a grip portion and an attachment structure that is operably coupled to an automatic transmission for shifting the transmission. A locking member pivots with the shift lever and is moveably engageable with an engagement surface that defines a park position detent. When the locking member is engaged with the park position detent, the shift lever cannot be moved out of the park position. The mechanical linkage includes a driver-operated member which, when actuated, causes the mechanical linkage assembly to bias the locking member out of engagement with the park position detent. A solenoid disposed within the grip portion is coupled with the mechanical linkage assembly and includes a plunger that can prevent the mechanical linkage from biasing the locking member out of the park position detent. An installation method for a gear selector is also disclosed.Type: GrantFiled: June 18, 2007Date of Patent: March 29, 2011Inventors: Tamara J. Reppuhn, Jason N. Wright, Bernard J. Emmendorfer, Frank R. Keipert, Richard P. Nash, Michael C. Vermeersch

Patent number: 7823478Abstract: An adjustable steering column assembly having an outer jacket, an inner jacket, and a tilt housing. A longitudinal locking device moves between released and engaged positions allowing and preventing longitudinal movement of the inner jacket relative to the outer jacket. A tilt locking device moves between released and engaged positions allowing and preventing tilting movement of the tilt housing relative to the inner jacket. A control lever is coupled to both of the longitudinal locking device and the tilt locking device for simultaneously moving the devices between the released and engaged positions. The longitudinal locking device has first and second members each having interengaging chamfers. The first member has an engagement surface abutting an abutment surface of the inner jacket when in the engaged position to prevent the longitudinal movement of the inner jacket relative to the outer jacket.Type: GrantFiled: September 26, 2006Date of Patent: November 2, 2010Assignee: GM Global Technology Operations, Inc.Inventors: Hitonobu Ohtsu, Richard P.

Patent number: 7640824Abstract: An adjustable steering column assembly of a vehicle has a central lock device for selectably locking an adjustable steering housing and co-extending steering shaft to a stationary bracket or chassis. For driver convenience and comfort, the steering housing and shaft are together adjustable with respect to the bracket. The lock device has a roller actuator preferably having inner outer members with a lever supported operably in between by a guide feature for movement along a first centerline substantially parallel to the steering shaft. Preferably, cam couplers are located between the outer member and the lever and the inner member and the lever for converting movement of the lever along the centerline to longitudinal movement of a carrier that traverses the centerline.Type: GrantFiled: May 15, 2007Date of Patent: January 5, 2010Assignee: GM Global Technology Operations, Inc.Inventors: Marvin V. Manwaring, Ravi Ravindra, Amelia M. Lask, Melvin L. Tinnin, Richard P. Nash

Patent number: 7621197Abstract: A steering column assembly of a vehicle has a releasable push/pull lock device for selectably locking an adjustable steering housing and co-extending steering shaft to a stationary bracket or chassis. For driver convenience and comfort, the steering housing and shaft are together adjustable with respect to the bracket. The lock device has a toggle apparatus having a push/pull lever that may extend substantially parallel to a rotating axis of the steering shaft and move in a first direction along its length and between locked and unlocked positions. A carrier of the device connects to the toggle apparatus and moves along its length in a second direction that may be perpendicular to the first direction and as the lever moves between the locked and unlocked positions. Preferably, an indexing apparatus is generally carried between the carrier and at least one of the housing and the bracket for selecting adjustment of the steering column assembly when the device is in the unlocked position.Type: GrantFiled: March 21, 2007Date of Patent: November 24, 2009Assignee: GM Global Technology Operations, Inc.Inventors: Marvin V.

Patent number: 7533594Abstract: A position control apparatus for a motor vehicle steering column includes an outer bracket, an inner bracket moveable relative to the outer bracket, and a jacket mounted to the inner bracket for telescoping movement along a longitudinal axis and for tilting movement. A first rack is mounted to the inner bracket and extends along the longitudinal axis. A first pinion is rotatable along the first rack during telescoping movement. A second rack is mounted to the outer bracket and extends angularly relative to the longitudinal axis. A second pinion is rotatable along the second rack during tilting movement. The first pinion has a first locking surface and the second pinion has a second locking surface. The first locking surface and the second locking surface may be engaged with each other to prevent telescoping and tilting movement or may be disengaged from each other to allow telescoping and tilting movement.Type: GrantFiled: December 13, 2006Date of Patent: May 19, 2009Assignee: Delphi Technologies, Inc.Inventors: Damir Menjak, Allan L.

Patent number: 7503234Abstract: A steering column assembly has a steering column with a longitudinal axis and disposable in a vehicle for tilting movement and telescoping movement. A wedge lock is engaged with the steering column and moveable between a first unlocked position and a first locked position along a first path to selectively lock the steering column with respect to the telescoping movement. A force required to move the wedge lock increases along the first path from the first unlocked position to the first locked position. A lever is pivotally engaged with the steering column about a pivot axis for rotation between an adjusting position and a locking position. The wedge lock moves from the first unlocked position to the first locked position along the first path in response to rotation of the lever from the adjusting position to the locking position. A cable assembly includes a cable with first and second ends and a sheath substantially encircling the cable.Type: GrantFiled: May 26, 2005Date of Patent: March 17, 2009Assignee: Delphi Technologies, Inc.Inventors: Ray G. Armstrong, Richard P. Nash, Neal R. Roller, Philip J. McCarthy
