Publication number: 20040150206Abstract: A steering column assembly has a tilt head for rotating a steering column. A spring lock assembly locks the tilt head in any of an infinite number of pivotally adjusted positions and includes a locking bar and a coil spring. The coil spring has coils which are wrapped around and grip the locking bar to lock the tilt head in a selected pivotally adjusted position. A tilt release is provided to release the grip of the coils on the locking bar to enable the tilt head to be pivoted to another pivotally adjusted position.Type: ApplicationFiled: February 3, 2003Publication date: August 5, 2004Inventors: Marvin V. Manwaring, Melvin Lee Tinnin, Ravindra Jwalapathy, Ray Garnet Armstrong

Patent number: 6761376Abstract: A vehicle steering column has a rake adjustment mechanism which includes a rake bracket having a rake slot provided with rake slot teeth. A tooth lock is supported in the rake slot with teeth opposing the rake slot teeth. A rake bolt is rotatable to a first rotative position to move the tooth lock to a retracted position with the teeth of the tooth lock out of engagement with the rake slot teeth. The bolt is axially rotatable to a second rotative position permitting the tooth lock to be moved to a locking position by a spring in which the teeth of the tooth lock engage the rake slot teeth. The bolt, when in the second rotative position, is movable, in response to an application of an impact force on the steering column to collapse the steering column, into bearing engagement with the tooth lock to positively retain the tooth lock in the locking position. The steering column is also provided with a release mechanism having shear pins and an energy absorption mechanism.Type: GrantFiled: May 27, 2003Date of Patent: July 13, 2004Assignee: Delphi Technologies, Inc.Inventors: Richard Kremer Riefe, Marvin V. Manwaring, Ray Garnet Armstrong, Ravindra Jwalapathy, Stephen W. Skillman

Patent number: 6749222Abstract: An energy absorbing device for a collapsible steering column has a plurality of plastically deformable straps each with one end connected to the steering column and an opposite end bent around an anvil connected to stationary vehicle support structure. When the steering column collapses, the straps unwind from the anvils, thereby resisting steering column collapse and absorbing energy. One or more of the straps may be cut in two by a knife at the time of the collision, thereby removing it from the energy absorbing system. In another form of the invention, an energy absorbing strap extends around a piston which has two or more different size anvils. The piston is axially movable in a cylinder to positions surrounding one or another of the anvils. The strap is drawn over the anvil it surrounds when the steering column collapses, thereby resisting collapse of the steering column and absorbing a certain amount of energy depending on the size of the anvil.Type: GrantFiled: October 10, 2002Date of Patent: June 15, 2004Assignee: Delphi Technologies, Inc.Inventors: Marvin V. Manwaring, Melvin Lee Tinnin, Ravindra Jwalapathy, Ray Garnet Armstrong

Publication number: 20040004348Abstract: An energy absorbing assembly providing variable energy absorption from an energy transmitting component is mounted upon a mounting bracket for mounting the energy absorbing assembly to the energy transmitting component. An elongated strap immovably secured at a first end absorbs energy received from the energy transmitting component during a collision. Cooperating anvils are slidably received by the mounting bracket and the elongated strap is interwoven between the anvils. The anvils include generally parallel axis along which each anvil defines stepped diameters, and are slidable along the axis in response to a predetermined force to provide variable energy absorption relative to the stepped diameters.Type: ApplicationFiled: May 8, 2003Publication date: January 8, 2004Inventors: Marvin V. Manwaring, Lee M. Tinnin, Ravindra Jwalapathy, Ray G. Armstrong, Richard K. Riefe

Publication number: 20040000779Abstract: An electrically actuated steering column system that includes an electrically actuated steering column mechanism. A switch is interconnected with the electrically actuated steering column mechanism to allow for movement of a steering column housing relative to a driver. There is also included electrical control structure that regulates the electrically actuated steering column mechanism. The electrically actuated steering column system allows a driver to activate a switch and apply a force to initiate movement of the steering column housing and then deactivate the switch to halt movement and retain the steering column housing in a secure manner.Type: ApplicationFiled: June 27, 2002Publication date: January 1, 2004Inventors: Ray G. Armstrong, Richard K. Riefe, Ravindra Jwalapathy, Marvin V. Manwaring

Publication number: 20030226417Abstract: An interactive energy absorbing system including a steering column housing that is moveable along a collapse stroke corresponding to a force of impact by an operator. The interactive energy absorbing system includes an energy absorbing component that exerts a resistant force for resisting the movement of the steering column housing along its collapse stroke. The energy absorbing component includes a deformable strap that engages a stationary reaction member and a moveable reaction member, The stationary and moveable reaction members have an adjustable total active surface area for engaging the deformable strap and generating the resistance force. The moveable reaction member moves to adjust the total active surface area due to mechanical translation corresponding to the force of impact by the operator.Type: ApplicationFiled: June 7, 2002Publication date: December 11, 2003Applicant: Delphi Technologies, Inc.Inventors: Marvin V.

Patent number: 6616185Abstract: The vehicle steering column has a rake adjustment and a telescope adjustment. The adjustment mechanism includes a compression bracket with a telescope slot, a rake bracket with a rake slot and a rake bolt that passes through the telescope slot and the rake slot. A wedge lock is mounted on the rake bolt and positioned in the rake slot and the telescope slot. Rake and telescope teeth on the wedge lock are held out of engagement with a rake tooth rack and a telescope tooth rack during rake and telescope adjustment. The rake bolt is tightened to hold a selected adjustment position and the telescope teeth on the wedge lock engage the telescope tooth rack. During a collision the rake teeth on the wedge lock are moved into engagement with the rake tooth rack to fix the rake and telescope adjustments.Type: GrantFiled: June 21, 2002Date of Patent: September 9, 2003Assignee: Delphi Technologies, Inc.Inventors: Marvin V.
