  • Publication number: 20070245845
    Abstract: An adjustable steering column assembly for a vehicle has an integral rake pivot joint carried between a mounting structure generally attached to the vehicle chassis and a support bracket that pivots about a pivot axis. A preferably telescoping shaft extends along a centerline and connects to a steering wheel at one end and is rotationally supported near an opposite end by the support bracket. Preferably, the pivot axis is orientated substantially perpendicular to the centerline. The pivot joint has a boss preferably elongated with respect to the pivot axis and generally orientated concentrically to the pivot axis. The boss fits pivotally in a bore disposed concentrically to the pivot axis and carried by the other of the mounting structure and support bracket. Preferably, a web portion of the boss projects through a slit extending axially and communicating radially inward with the bore.

  • Publication number: 20070039403
    Abstract: 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.

  • Publication number: 20070008083
    Abstract: A steering column assembly (18) of the type for controlling one or more steerable wheels in a motor vehicle includes a steering wheel (14) interface secured to the free end of a steering column (20). The steering column assembly (18) includes powered telescope adjust and tilt adjust features which a driver (16) uses to adjust the position of the steering wheel (14) for maximum comfort. One or more condition sensors (48) monitor numerous parameters about the vehicle. When an emergency condition is detected, such as the seat belt warning, a door that is ajar, various engine conditions, or erratic driving activity, a haptic controller (50) rapidly vibrates the steering wheel (14) through the telescoping and tilt adjusting motors (32, 40) as a means of alerting the driver (16) to the emergency condition.

  • Publication number: 20060243088
    Abstract: A telescopically adjustable vehicular steering column assembly (16) includes an upper steering shaft (18, 118) operatively coupled to a lower steering shaft (20, 120). The lower steering shaft (20, 120) is fitted with a guide head (32, 132) which is precision machined to slide within a receiving chamber (28, 128) in the upper steering shaft (18, 188). An axially extending keyway (40, 140) is formed in either the guide head (32) or in the receiving chamber (128) for sliding registry with a key (44, 144). The guide head (32, 132) is affixed to the end of the lower steering shaft (20, 120) through a sheer member (35) which is created by injecting a fluidic plastic material (35) through injection ports (34) so that the plastic forms in injection grooves (36). Once solidified, the plastic material (35) securely affixes the guide head (32, 132) in an operative position on the end of the lower steering shaft (20, 120).

  • Publication number: 20060226646
    Abstract: A vehicular steering column assembly (16) comprises a support bracket (26) which is joined to an outer, non-rotating sleeve (22). A release capsule (30) is releasably joined to a mounting surface (28) of the support bracket (26) via a plurality of spherical bodies (56) whose protruding crowns (52) are seated in corresponding longitudinally-extending furrows (54) in the release capsule (30). Upon the application of sufficient force to the steering column (16), such as during a collision, the support bracket (26) is urged out of engagement with the release capsule (30) with the respective furrows (54) sliding over the crowns (52). The sliding engagement between the crowns (52) and the furrows (54) can be adjusted to establish a highly predictable and consistent release force and which is capable of increasing the frequency value for the steering column (16).
