A steering column assembly includes a jacket assembly and an energy absorption strap assembly. The energy absorption strap assembly has a first energy absorption strap and a second energy absorption strap. The first energy absorption strap has a first strap body that extends between a first strap first end and a first strap second end. The first strap body defines a first opening and a second opening. The second energy absorption strap has a second strap body that extends between a second strap first end and a second strap second end. The second strap first end is at least partially received within the first opening and the second strap second end is at least partially received within the second opening.

The invention provides a locking device for a tilting and telescoping steering column. The locking device provides a single mechanism for substantially preventing movement of the upper steering column jacket relative to the lower steering column jacket and also for preventing tilting movement of the tilt housing relative to the upper steering column jacket. The locking device includes a linking member that extends parallel to the upper steering column jacket. The linking member is pivotally connected to the tilt housing and slidably connected to the lower steering column jacket. A wedge member is positioned between the linking member and the upper steering column jacket adjacent to the lower steering column jacket. The wedge member is rotatable between a locked position and an unlocked position. In the locked position, the wedge member urges the linking member away from the upper steering column jacket in a direction transverse to the upper steering column jacket.

A steering column assembly is disclosed featuring a steering column carried by a release bracket having parallel connecting walls interposed between spaced sidewalls of a mounting bracket, which is for attachment to a vehicle subassembly. Shear capsules are releasably disposed within respective rearwardly-opening primary notches on the connecting walls. The capsules are connected to the mounting bracket by being disposed in respective secondary notches on the sidewalls. The capsules shear in response to an axial shear force above a predetermined threshold value and release the connecting walls to permit the steering column to collapse.

An intermediate steering shaft for a motor vehicle steering system including a tabular outer shaft, a tubular center shaft slidably telescoped in the outer shaft, and a solid inner shaft slidably telescoped in the center shaft and all coupled for unitary rotation by respective pairs of flat sides on each. Each of the flat sides of the tubular center shaft is interrupted by a pair of outward facing shallow grooves always concealed in the overlap between the tubular outer and center shafts. One of the flat sides in the tubular center shaft is further interrupted by an exposed shallow groove located near a distal end of the outer shaft in an extended or normal position of the tubular center shaft. A plastic end fitting is in situ injection molded on the tubular outer shaft and includes a pair of thin, flat slide bearings in the concealed shallow grooves, a plurality of shear pins in the inlet and discharge passages, and a collar around the distal end of the outer shaft and an adjacent portion of the center shaft. If the shear pins are fractured inadvertently, a lip of the collar engages an edge of the exposed shallow groove to obstruct telescoping of the tubular center shaft into the tubular outer shaft.
