Publication number: 20080277178Abstract: A steering wheel assembly has a steering wheel armature, a hub portion and spokes. The hub portion is fixable to a conventional steering column shaft. The steering wheel assembly has a first drum supported on the steering column shaft, to freely rotate about only the axis of the steering column shaft. A second drum is freely rotatable with respect to the first drum only about a second axis. The second axis is parallel to and spaced apart from or incident to of the steering column shaft. Stationary means are provided for supporting the second drum on the first drum. Both the first drum and the second drum are rotated around their respective axes by the spokes engaging their sidewalls. The support provides a stationary support member onto which an airbag module or other devices can be mounted.Type: ApplicationFiled: January 30, 2008Publication date: November 13, 2008Applicant: KEY SAFETY SYSTEMS, INC.Inventors: Valerio Poli, Andrea Anselmi, Roberto Ridolfi, Adolfo Ridolfi

Patent number: 7023106Abstract: A steering column assembly having a support structure, a tilt portion, and a switch module is provided. The support structure is securable to a vehicle. The tilt portion is pivotally secured to the support structure such that the tilt portion can pivot about a pivot axis through a selected range of motion with respect to the support structure. A first electrical connecting member is disposed on the tilt portion proximate the pivot axis. The switch module has a second electrical connecting member connected to the first electrical connecting member such that the switch module in electrical communication with a wiring harness.Type: GrantFiled: October 7, 2002Date of Patent: April 4, 2006Assignee: Delphi Technologies, Inc.Inventor: Todd M.

Patent number: 6909951Abstract: A fail-safe torque transducer, and automotive power steering system, utilizing a two-stage series coupled torsion bar system. A first stage torsion bar provides tuning of the steering system, and by reducing its diameter relative to the second stage, provides a lower torsional spring rate and higher operational stress level than that of the second stage. The second stage torsion bar provides the stress/strain indicia referenced by a torque-measuring device, and is stressed at a lower level than the first stage and therefore has a higher cycle life than that of the first stage bar. Hence, if stress related failure ever occurs, it will only occur in the first stage torsion bar, thereby preventing any torque from reaching the second stage, thereby causing a zero strain signal and thus rendering the system fail-safe and not subject to instability of vehicle steering if the torsion bar breaks.Type: GrantFiled: September 12, 2003Date of Patent: June 21, 2005Assignee: Dana CorporationInventors: David R. Llewellyn, William G. Spadafora, Jason G. Kramer

Patent number: 6877582Abstract: Steering equipment for a work vehicle includes a steering transmission shaft mounted so that the shaft can turn within a steering column, and with a control device for actuating a steering operating unit. The control device includes a reference member, which can move along the transmission shaft and a sensor device fixed to the steering column in a position substantially facing the reference member for detecting a position of the reference member along the transmission shaft. The sensor provides a displacement signal that is used to vary the steering ratio, such as steering speed.Type: GrantFiled: March 5, 2003Date of Patent: April 12, 2005Assignee: Case, LLCInventors: Paolo Ferracin, Marcello Mongiardo, Franco Mazzucchi, Alessandro Scotti

Patent number: 6581714Abstract: Improvements to a motorized balancing personal transporter. An intelligent battery has a battery container sealed against moisture and a plurality of battery blocks housed within the battery container. Additionally, the battery pack has a plurality of sensors, each of which is for monitoring a characteristic of a distinct battery block. The battery pack has a processor that generates a fault flag for transmission to a circuit external to the battery container on occurrence of a critical fault and that transmits an identifying characteristic such as a battery serial number. Various mechanisms are provided for receiving rider input in order to direct steering of the vehicle. These include a rotatable grip for imparting rotary motion to a rotation sensor, a thumb-activated rotation sensor and a palm-activated sensor, each disposed on the handlebar of the vehicle.Type: GrantFiled: October 13, 2000Date of Patent: June 24, 2003Assignee: DEKA Products Limited PartnershipInventors: Dean L. Kamen, Richard William Arling, J. Douglas Field, John B. Morrell, Jonathan B. Pompa

Patent number: RE39440Abstract: The snap-on steering column shroud assembly includes an upper shroud and a lower shroud. The upper shroud has an upper steering shaft passage portion that is positioned vertically, axially and angularly relative to the upper steering shaft. A front edge is moved toward the steering column to move upper shroud cantilever snap fasteners into engagement with the steering column. Force is applied manually to force the upper shroud snap fasteners into a retaining position. A lower shroud is aligned with the upper shroud by alignment posts and alignment post receivers and then raised into contact with the steering column. Lower shroud cantilevered snap fasteners are manually forced into a lower shroud retaining position on the steering column. Snap connectors and snap receivers connect the upper shroud to the lower shroud.Type: GrantFiled: January 29, 2004Date of Patent: December 26, 2006Assignee: Delphi Technologies, Inc.Inventors: Michael Patrick Anspaugh, Robert W. Dubay, Timothy D. Beach, Matthew J. Allington, Henry A. Eurich
