Patent number: 6557434Abstract: The steering column tilt assembly has a tilt housing that is pivotally attached to a fixed housing. A fixed shoe is attached to the fixed housing. A pivoted shoe is pivotally attached to the tilt housing. A shoe release lever has a wedge surface that holds the pivoted shoe in engagement with a fixed shoe when in a locked position. The shoe release lever has two trunions that are received in bores in the tilt housing. A release lever slot between the bores receive the pivot end shank portion. An open quadrant of the lower bore portion permits the shank portion to be moved into the slot. A spring urges the shoe release lever toward the locked position.Type: GrantFiled: April 2, 2001Date of Patent: May 6, 2003Assignee: Delphi Technologies, Inc.Inventors: Ray Garnet Armstrong, James Anthony Smazenka, Richard Kremer Riefe

Patent number: 5715730Abstract: A tilt adjustable motor vehicle steering column having a mast jacket on a motor vehicle body structure, a tilt housing supported on the mast jacket for pivotal movement about a lateral centerline of the steering column, a steering wheel rotatably supported on the tilt housing, a tilt latch for immobilizing the tilt housing, and an inertia-actuated secondary restraint operative independent of the tilt latch to prevent upward pivotal movement of the tilt housing. The secondary restraint includes a spool rotatably supported on the mast jacket, a tether on the spool having an end attached to the tilt housing, and an inertia-actuated latch operative to block rotation of the spool in response to high negative acceleration of the motor vehicle. The inertia-actuated latch includes a plurality of radial abutments on the spool, a pawl engageable on the radial abutments, and a pendulum operative to pivot the pawl into engagement on the radial abutments.Type: GrantFiled: June 10, 1996Date of Patent: February 10, 1998Assignee: General Motors CorporationInventors: Richard Kremer Riefe, Howard David Beauch, Roger Allen Bourbina

Patent number: 5657668Abstract: A tilt type steering apparatus makes the amount of downward protrusion of the front end position of a rear steering column small to prevent interference with knees and prevents the rear steering column from becoming longer than necessary. A first lateral shaft connects a front steering column to a rear steering column. A second lateral shaft, provided under the rear steering column, is rockable about the first lateral shaft. An engagement member is pivotally supported by the second lateral shaft, and displacement side meshing teeth are formed on an upper edge of a front end portion of the engagement member. Fixed side meshing teeth are formed on a lower surface of a restraining member fixed to a lower surface of a support bracket. The displacement and fixed side meshing teeth are engaged and disengaged with each other by a rocking movement of a tilt lever.Type: GrantFiled: July 26, 1995Date of Patent: August 19, 1997Assignee: NSK, Ltd.Inventors: Tadashi Hibino, Akira Aida, Sakae Matsumoto, Mikio Yamaguchi
