Patent number: 8297145Abstract: An adjustable steering column assembly having a column jacket defining a longitudinal axis and moveable in at least one of a telescoping direction and a tilting direction is disclosed. A bracket is coupled to the column jacket with at least one pivot shaft coupled to the bracket along a pivot axis. A lever is mounted to the pivot shaft and rotates between a set position for preventing movement of the column jacket and an adjustable position for allowing movement of the column jacket. A locking device engages the lever and moves between a locked position and an unlocked position in response to rotation of the lever between the set and adjustable positions, respectively. A restrictor encircles the bracket, the column jacket, the lever and the locking device for resisting against an outwardly radial force produced by the locking device when in the locked position.Type: GrantFiled: April 11, 2011Date of Patent: October 30, 2012Assignee: Steering Solutions IP Holding CorporationInventor: Leland N.

Patent number: 8123251Abstract: An adjustable steering column assembly for a vehicle preferably has a bracket for rigid attachment to the vehicle with a first slot defining a longitudinal adjustment path of the assembly. A steering shaft is journaled to a jacket of the assembly for rotation about an axis. A shuttle attaches rigidly to the jacket and adjustably to the bracket for telescoping and tilt adjustment of the assembly. The shuttle has a second slot that defines a collapse path with said second slot preferably having a first portion restraining said steering shaft in a normal state and a second portion that allows said steering shaft to move through said collapse path when in a collapsed state. A pin extends through said first and second slots for coupling said shuttle to said bracket.Type: GrantFiled: December 17, 2009Date of Patent: February 28, 2012Assignee: Steering Solutions IP Holding CompanyInventors: Leland N.

Patent number: 7478969Abstract: A rotatable combination that includes first and second members respectively having first and second longitudinally extending pluralities of splines. The second plurality of splines extend substantially parallel to the rotational axis. The first plurality of splines includes first and second longitudinally extending sections having different orientations with the second longitudinal section defining an angle with the rotational axis. The first longitudinal section engages the second plurality of splines before the second longitudinal section during assembly of the two members. Engagement of the second longitudinal section with the second plurality of splines generates a greater resistance to longitudinal movement than engagement of the first longitudinal section with the second plurality of splines.Type: GrantFiled: January 27, 2006Date of Patent: January 20, 2009Assignee: Delphi Technologies, IncInventors: Keith A.

Patent number: 5590565Abstract: A motor vehicle steering column having power adjustment of the horizontal and vertical positions of a steering wheel on an end of the steering column including an adjustable tubular mast jacket on which the steering wheel is supported, a stationary tubular mast jacket, and a self-adjusting slide bearing between the stationary and adjustable mast jackets. The self-adjusting slide bearing includes a support tube on the stationary mast jacket, pair of inward facing frustoconical seats on the support tube, a pair of plastic split sleeve bearings slidably mounted on the adjustable mast jacket each having an outward facing frustoconical side, and a tubular spring between the split sleeve bearings biasing the latter toward converging annuluses defined between the frustoconical seats and the adjustable mast jacket for lash-free sliding support of the adjustable mast jacket on the stationary mast jacket.Type: GrantFiled: February 8, 1995Date of Patent: January 7, 1997Assignee: General Motors CorporationInventors: Samuel R.

Patent number: 4990021Abstract: A detent connection between a hidden release lever of a tilt-adjustable automotive steering column and an exposed hand lever of the steering column, the connection including a D-shaped socket in a tab on the release lever and a D-shaped plug-end on the hand lever. The flat portions of the D-shaped socket and plug-end face each other and each has a trough therein extending the full length of the flat portion and facing the trough in the other flat portions. The facing troughs define a detent tunnel in which a cylindrical coil spring is disposed in radial compression. The spring engages the troughs along the full lengths thereof to torsional and lonitudinal rigidity.Type: GrantFiled: April 30, 1990Date of Patent: February 5, 1991Assignee: General Motors CorporationInventor: Leland N.

Patent number: 4886460Abstract: An electrical connector arrangement for a steering column occupant cushion restraint system is provided to provide continuous electrical continuity between a sensor and an occupant restraint cushion when the steering wheel shaft is rotated relative to the steering column. The electrical connector arrangement includes a continuous coil which is wound and unwound depending on the direction of which the steering wheel is rotated and includes an automatic locking and unlocking means which automatically prevents any significant relative rotation between the inner and outer housings of the connector arrangement when the electrical connection arrangement is removed for service and which automatically allows relative rotation therebetween in response being connected or reconnected onto the steering column so that the continuous coil cannot be wound tighter while being removed for service.Type: GrantFiled: February 27, 1989Date of Patent: December 12, 1989Assignee: General Motors CorporationInventor: Leland N. Olgren

Patent number: 4867003Abstract: A collapsible, energy absorbing steering column with staged energy absorption. A sleeve around a lower mast jacket of the column has a primary part in the annulus defined by the overlap between the lower mast jacket and an upper mast jacket of the column and a secondary part outside the annulus. A plurality of primary roll deforming steel balls in interference in the annulus are also loosely received in pockets in the sleeve primary part. A plurality of secondary roll deforming steel balls are loosely received in the sleeve secondary part outside the annulus and held on the sleeve by a strippable retainer. When the column collapses, the secondary roll deforming steel balls enter the axially expanding overlap between the mast jackets to increase the level of energy absorption.Type: GrantFiled: December 19, 1988Date of Patent: September 19, 1989Assignee: General Motors CorporationInventors: Howard D. Beauch, Leland N. Olgren
