A steering column assembly includes an energy absorption assembly. The energy absorption assembly includes an energy absorption strap, a bracket, a pin, and a cam member. The energy absorption strap includes a plurality of engagement members. The bracket is disposed on at least one of a lower jacket assembly and an upper jacket assembly. The bracket has a first wall disposed opposite a second wall. The pin extends through the first wall and the second wall to couple the cam member to the bracket. The cam member has a plurality of complementary engagement members configured to engage the plurality of engagement members.

Steering column assembly

An energy absorbing system includes a subject structure, an energy absorbing strap associated with the subject structure, and a retaining device to selectively retain the energy absorbing strap during an energy addition event. The retaining device surrounds both an upper and lower portion of the energy absorbing strap.

Energy absorbing strap retaining device

An adjustable steering column assembly includes a support bracket, a jacket assembly, and a locking assembly. The support bracket is configured to connect to a vehicle. The jacket assembly is connected to the support bracket. The locking assembly is connected to and disposed between the support bracket and an adjustment lever. The locking assembly includes an inner cam connected to the support bracket and an outer cam rotatably connected to the inner cam and connected to the adjustment lever. The adjustment lever and the outer cam are movable between an unlock position and a lock position.

Adjustable steering column assembly

A portion of a steering column assembly includes an energy absorption assembly. The energy absorption assembly includes an energy absorption strap and a breakaway member. The energy absorption strap has a first strap portion coupled to an upper jacket assembly and a second strap portion coupled to a lower jacket assembly. The breakaway member has a first breakaway member, a second breakaway member, and a frangible area. The first breakaway member defines a first opening that receives the first strap portion. The second breakaway member defines a second opening that receives the second strap portion. The frangible area joins the first breakaway member to the second breakaway member.

Steering column having an energy absorption assembly

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.

Collapsible steering column assembly

An adjustable steering column assembly with a steering shaft extending through a jacket member. An elongate locking member extends through two opposed sidewalls and a compression member positioned between the sidewalls. One of either the sidewalls or the compression member is fixed relative to the jacket member while the other is fixed relative to the vehicle structure. Spacers are located on opposite sides of the compression member between the compression member and the two sidewalls. First and second abutment surfaces are engaged with outward facing surfaces of the sidewalls and are coupled to the elongate locking member. An actuator assembly moves the locking assembly between unlocked and locked positions. In the locked position, the abutment surfaces bias the sidewalls inwardly to firmly engage the compression member between the spacers.

Adjustable steering column assembly with compressive locking mechanism

A tilt adjustable motor vehicle steering column having a mast jacket on a motor vehicle body structure, a tilt housing supported on the mast jacket for pivotal movement about a lateral centerline of the steering column, a steering wheel rotatably supported on the tilt housing, a tilt latch for immobilizing the tilt housing, and an inertia-actuated secondary restraint operative independent of the tilt latch to prevent upward pivotal movement of the tilt housing. The secondary restraint includes a spool rotatably supported on the mast jacket, a tether on the spool having an end attached to the tilt housing, and an inertia-actuated latch operative to block rotation of the spool in response to high negative acceleration of the motor vehicle. The inertia-actuated latch includes a plurality of radial abutments on the spool, a pawl engageable on the radial abutments, and a pendulum operative to pivot the pawl into engagement on the radial abutments.
