Publication number: 20120112443Abstract: Construction of a steering column support apparatus is achieved that is able to suppress an increase in the height dimension, maintain a function of the steering column 6a being able to displace smoothly in the forward direction during a secondary collision and prevent the steering column from dropping down even when the steering column 6a is displaced in the forward direction due to a secondary collision. The steering column support apparatus comprises a non-dropping bracket 45 that is fastened to the vehicle body, a dropping bracket 46 that is supported by the steering column 6a, a pair of bolts 47 and a pair of support capsules 16a. During a secondary collision, the supporting force of the support capsules 16a for supporting the non-dropping bracket 45 is lost and the steering column 6a displaces in the forward direction together with the bolts 47, support capsules 16a and dropping bracket 46, however, does not drop from the non-dropping bracket.Type: ApplicationFiled: June 13, 2011Publication date: May 10, 2012Applicant: NSK Ltd.Inventors: Tetsuo Arakawa, Hiroshi Fukuda

Patent number: 8141453Abstract: When a steering column contracts in order to absorb shock, interference between a column cover and a lock apparatus is suppressed, and a shock-absorbing stroke of the steering column is obtained. When a steering column contracts in order to absorb shock as a result of an input load equal to or greater than a predetermined value, a column cover that covers a rear end side of steering column, performs a stroke, together with a movable side region, relative to an outer tube (a fixed side region) of steering column, to which is fixed a lock apparatus. At this time, a side wall portion of column cover, which is positioned further to a vehicle rear than lock apparatus, enters between lock apparatus and outer tube of steering column, thereby suppressing interference between column cover and lock apparatus.Type: GrantFiled: January 5, 2009Date of Patent: March 27, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventors: Osamu Fukawatase, Akiyoshi Sanada

Patent number: 8127639Abstract: A telescopically collapsible vehicular steering column assembly includes inner and outer shaft tubes which are joined in a sliding fit by a bushing. The bushing includes a pair of spaced journal bearings formed of steel-backed PTFE held in a plastic carrier body. The bushing is located in a receiving chamber in the outer shaft tube. A clearance compensator reacts against the receiving chamber to exert a radial compressive force through the carrier body and the journal bearings to improve the sliding fit with the inner shaft tube and remove lash. The clearance compensator can take any form, such as a hollow annular rib, a skirt with a flexible free end, or an array of nubs carried in thinned sections of the carrier body. The clearance compensator in all of these variations operates within a clearance space and has dimensional attributes which can be changed during the design and manufacturing phases of the bushing to optimize a characteristic of the steering column assembly.Type: GrantFiled: August 16, 2005Date of Patent: March 6, 2012Assignee: Steering Solutions IP Holding Company, a Delaware corporationInventors: Marvin V.

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: 8096036Abstract: A method of manufacturing a steering column assembly having a first jacket and a second jacket with a bushing between the first and second jackets. The method utilizes a manufacturing machine having a loadable member, a fixed member, and a thermal fixture. The method comprises the steps of: assembling the first jacket to the second jacket with the bushing located radially between the first and second jackets to interlock the first and second jackets and prevent axial movement between the first and second jackets; connecting the first jacket to the loadable member of the manufacturing machine; connecting the second jacket to a fixed member of the manufacturing machine; loading the loadable member to apply an axial force to the first jacket; heating the thermal fixture of the manufacturing machine; and melting the bushing until the first jacket moves axially relative to the second jacket.Type: GrantFiled: August 29, 2007Date of Patent: January 17, 2012Inventors: Robert W.
