Patent number: 8960050Abstract: The invention provides a lever assembly for controlling a lock of a steering column assembly. The lever assembly includes a first lever portion pivotable about a locking axis between a locked position for substantially preventing adjusting movement of a steering column assembly and an unlocked position spaced from the locked position. The steering column assembly is moveable in adjusting movement when the first lever portion is in the unlocked position. The lever assembly also includes a second lever portion defining a handle portion and operable to rotate about the locking axis. The lever assembly also includes a lost motion linkage disposed between the first lever portion and the second lever portion. The lost motion linkage is operable to transmit rotation of the second lever portion about the locking axis to pivot the first lever portion between the locked position and the unlocked position.Type: GrantFiled: April 24, 2009Date of Patent: February 24, 2015Assignee: Steering Solutions IP Holding CorporationInventors: William D.

Patent number: 8955882Abstract: An inner column 2 is fitted in an outer column 1 in such a way as to be able to slide in the axial direction. The outer column 1 is mounted on a vehicle body 5 by a vehicle mount bracket 3. Fastening portions 65B, 65B of a right distance bracket 6B pass through through-holes 13, 14 respectively to be able to be in contact with the outer circumference 21 of the inner column and directly fasten the outer circumference of the inner column. Thus, there is provided a steering apparatus that is simple in structure without need to provide an additional mechanism for preventing rotation of an inner column and in which the magnitude of fastening force exerted on the inner column does not vary depending on the telescopic position of the steering wheel.Type: GrantFiled: July 19, 2012Date of Patent: February 17, 2015Assignee: NSK Ltd.Inventor: Masajirou Watanabe

Patent number: 8955407Abstract: It might happen that an inner column 3 is released from telescopic clamping and tilt clamping by an outer column 4 in a state before a vehicle fitting bracket 2 is fitted to a vehicle body. When a male steering shaft 6 is to escape from a female steering shaft 5, a come-out preventive member 7 is intruded into an inner peripheral annular groove 52 vicinal to an end portion of a female spline 51 on the front side with respect to the vehicle body. Then, the come-out preventive member 7 abuts on a shoulder portion 521 of the end portion, on the front side with respect to the vehicle body, of the inner peripheral annular groove 52, thereby surely enabling the male steering shaft 6 from escaping out of the female steering shaft 5.Type: GrantFiled: May 30, 2012Date of Patent: February 17, 2015Assignee: NSK Ltd.Inventor: Yuuichi Sakuma

Patent number: 8943923Abstract: In a steering system including a lock mechanism, at a time of locking, a first cam that is rotated together with a lock shaft generates a pressing force for pushing up an inner tube in an upward tilt direction. A second cam that is rotated together with the lock shaft presses an abutting portion of an urging member in a downward tilt direction. The abutting portion of the urging member applies a pressing reaction force in the upward tilt direction, to the second cam. The pressing reaction force serves as a force for pushing up the first cam in the upward tilt direction, through the second cam and the lock shaft.Type: GrantFiled: November 20, 2013Date of Patent: February 3, 2015Assignee: Jtekt CorporationInventor: Hideyuki Kakishita
