摘要:
A steering column assembly of a vehicle has a releasable push/pull lock device for selectably locking an adjustable steering housing and co-extending steering shaft to a stationary bracket or chassis. For driver convenience and comfort, the steering housing and shaft are together adjustable with respect to the bracket. The lock device has a toggle apparatus having a push/pull lever that may extend substantially parallel to a rotating axis of the steering shaft and move in a first direction along its length and between locked and unlocked positions. A carrier of the device connects to the toggle apparatus and moves along its length in a second direction that may be perpendicular to the first direction and as the lever moves between the locked and unlocked positions. Preferably, an indexing apparatus is generally carried between the carrier and at least one of the housing and the bracket for selecting adjustment of the steering column assembly when the device is in the unlocked position.

An adjustable steering column assembly of a vehicle has a central lock device for selectably locking an adjustable steering housing and co-extending steering shaft to a stationary bracket or chassis. For driver convenience and comfort, the steering housing and shaft are together adjustable with respect to the bracket. The lock device has a roller actuator preferably having inner outer members with a lever supported operably in between by a guide feature for movement along a first centerline substantially parallel to the steering shaft. Preferably, cam couplers are located between the outer member and the lever and the inner member and the lever for converting movement of the lever along the centerline to longitudinal movement of a carrier that traverses the centerline.

A position control apparatus for a motor vehicle steering column includes an outer bracket, an inner bracket moveable relative to the outer bracket, and a jacket mounted to the inner bracket for telescoping movement along a longitudinal axis and for tilting movement. A first rack is mounted to the inner bracket and extends along the longitudinal axis. A first pinion is rotatable along the first rack during telescoping movement. A second rack is mounted to the outer bracket and extends angularly relative to the longitudinal axis. A second pinion is rotatable along the second rack during tilting movement. The first pinion has a first locking surface and the second pinion has a second locking surface. The first locking surface and the second locking surface may be engaged with each other to prevent telescoping and tilting movement or may be disengaged from each other to allow telescoping and tilting movement.

An adjustable steering column assembly having an outer jacket, an inner jacket, and a tilt housing. A longitudinal locking device moves between released and engaged positions allowing and preventing longitudinal movement of the inner jacket relative to the outer jacket. A tilt locking device moves between released and engaged positions allowing and preventing tilting movement of the tilt housing relative to the inner jacket. A control lever is coupled to both of the longitudinal locking device and the tilt locking device for simultaneously moving the devices between the released and engaged positions. The longitudinal locking device has first and second members each having interengaging chamfers. The first member has an engagement surface abutting an abutment surface of the inner jacket when in the engaged position to prevent the longitudinal movement of the inner jacket relative to the outer jacket. The engagement and abutment surfaces are preferably uninterrupted along a longitudinal axis to provide an infinite number of adjustment positions for the inner jacket.

摘要:
A collapsible steering assembly features a guide bracket for attachment to a vehicle. A steering mechanism is interconnected with the guide bracket by a steering mechanism support. A plurality of guide rods are arranged about a common collapse axis and extend in non-parallel relationship to a longitudinal axis of the steering mechanism. The guide rods support the steering mechanism for axial movement along the collapse axis in response to a predetermined collapse force on the steering mechanism.
