摘要:
An energy absorbing device for a collapsible steering column of a vehicle is able to compensate for the severity of a crash and the weight of the driver to better manage the absorption of energy in a crash event. A housing has at least one fixed abutment surface, and at least one adjuster disposed in the housing for selective lateral slidable movement. At least one anvil is disposed adjacent an initial abutment surface of the adjuster in spaced relation to the fixed abutment surface of the housing in a first position of the anvil associated with high energy absorption. A plastically deformable strap is supported between the anvil and the housing. The adjuster slides out of the path of the anvil in a crash event in response to input of a control signal allowing the anvil to slide into contact with the fixed abutment surface of the housing to define a second position of the anvil associated with lower energy absorption.

The invention provides an apparatus including first and second steering column members engaged for pivotal movement relative to one another. The apparatus also includes a third steering column member supporting the first steering column member for sliding movement along an axis. The apparatus also includes a positive lock engaged with the first and second steering column members. The positive lock can operate in a locked configuration to prevent the pivotal movement. The positive lock can also operate in an unlocked configuration to allow the pivotal movement. The apparatus also includes a friction lock engaged with said first and third steering column members. The friction lock can operate in a locked configuration to prevent the sliding movement. The friction lock can also operate in an unlocked configuration to allow the sliding movement.

The invention provides a steering column assembly for a vehicle. The steering column assembly includes a lower steering column jacket for attachment to a vehicle. The steering column assembly also includes an upper steering column jacket engaged with the lower steering column jacket for telescoping movement along a longitudinal axis to support a steering wheel in a desired longitudinal position. The steering column assembly also includes a tilt housing engaged with the upper steering column jacket for tilting movement about a tilt axis to support the steering wheel in a desired angular position. The steering column assembly also includes a screw drive operably disposed relative to the lower steering column jacket. The screw drive includes a motor and a screw driven in rotation by the motor. The screw defines a centered, longitudinal screw axis. The steering column assembly also includes a nut assembly selectively engageable with the screw and fixedly engaged with the upper steering column jacket for controlling the telescoping movement.

A collapsible steering column is used with motor vehicle. The motor vehicle has a frame. The steering column has an outer jacket and a stationery bracket. The outer jacket is releasably coupled to the frame. The stationery bracket is coupled to the frame. The outer jacket and stationery bracket are collapsible in response to release of the outer jacket from the frame. An electrically actuated brake mechanism is coupled between the stationery bracket and the outer jacket and provides an infinitely variable resistive force to the collapse of the outer jacket and the stationery bracket.

An energy-absorbing motor vehicle steering column including a housing supported on a body structure of the vehicle for linear translation in a collapse direction and an energy absorber which converts into work a fraction of the kinetic energy of an impact on the steering column. The energy absorber includes a bare flat metal ribbon, i.e., without friction-reducing coating or lubrication, preformed to define a pair of parallel straight sections and a lateral web between the straight sections. The ribbon is seated edge-wise on a horizontal wall of the steering column housing with the straight sections in a pair of longitudinal guide channels and the lateral web looped over a pair of laterally spaced bare anvils on the housing and wedged between the bare anvils and an abutment on the body structure on the other side of the lateral web from the anvils. During linear translation of the housing in the collapse direction, the abutment anchors the center of the web on the vehicle body structure so that each of the straight sections of the flat ribbon is plastically deformed around and pulled across a corresponding one of the anvils to effect energy absorption by plastic deformation and by friction.
