An energy absorption system for a vehicle steering column includes a lower jacket. The energy absorption system also includes an upper jacket operatively coupled to, and moveable relative to, the lower jacket. The energy absorption system further includes a tooth rack operatively coupled to the upper jacket. The energy absorption system yet further includes an electromagnetic brake mechanism engageable with the tooth rack to exert a braking force on the tooth rack.

A steering column assembly includes a lower jacket. The steering column assembly also includes an upper jacket in telescoping engagement with the lower jacket. The steering column assembly further includes an energy absorbing strap assembly operatively coupled to the upper jacket. The energy absorbing strap assembly includes a strap having a stationary leg and a moveable leg connected by a curved portion to form a substantially U-shape. The energy absorbing strap assembly also includes a metal pin extending through the stationary leg and the moveable leg.

A steering column assembly includes a mounting bracket which is securely fixed to a car cross beam or the like; a support bracket located below the mounting bracket, the two brackets being connected together during normal operation by at least one frangible connector a telescopic shroud having a first portion that surrounds a steering shaft, the first portion being fixed to the support bracket, and an energy absorbing device. The energy absorbing devices further includes: a wire which extends along an underside of the mounting bracket and is secured at opposing ends to respective anchor portions of the mounting bracket, and a fixing part of the support bracket having an opening through which the wire passes, whereby in a crash the frangible connector is broken to permit the support bracket to move relative to the mounting bracket whereupon the wire is pulled through the opening in the fixing part.

Provided is a vehicle steering column. A lower column has an open area, an axial slot provided in a central portion of the open area, a connecting portion connecting portions of the lower column located on both sides of the open area, a cut portion corresponding to the slot and provided on one side of the connecting portion, and a pair of protruding opposite end portions. A hinge pin is fitted into the opposite end portions of the lower column. An upper column is fitted into the lower column. A telescopic fixing plate of the upper column is provided in a location corresponding to the slot, and has a plurality of catch recesses spaced apart from each other. A telescopic catch member is located in the cut portion between the opposite end portions to be rotatably supported by the hinge pin, and has a catch protrusion engaging with the catch recesses.

A steering column assembly includes a telescope drive bracket. The steering column assembly also includes a first jacket operatively coupled to the telescope drive bracket. The steering column assembly further includes a second jacket, wherein the first jacket is telescopingly moveable relative to the second jacket. The steering column yet further includes a collapse limiting feature having a cam portion and a blocking portion, wherein the blocking portion defines a first range of travel of the first jacket in a first position, wherein contact between the telescope drive bracket and the cam portion biases the blocking portion out of a first jacket path to allow a second, greater range of travel for the first jacket.

According to various example embodiments, there is provided a steering column for an automotive vehicle including, an inner tube 100 surrounding a steering shaft 120, an outer tube 110 into which the inner tube 100 is inserted, a nut screw 230 mounted on the outside of the outer tube 110 and fixed to the inner tube 100, and a first lead screw 210 which is inserted into the nut screw 230 and screwed therein and is rotated by a motor. In the steering column for the automotive vehicle, the nut screw 230 and the inner tube 100 are transferred together by translational motion by rotation of the first lead screw 210.

A steering column may include a casing pipe disposed longitudinally movably in a casing unit, a steering spindle rotatably supported about a longitudinal axis in the casing pipe, and a clamping device configurable in a fixing position for securing the casing unit relative to the casing pipe. The clamping device may have an engagement element supported on the casing pipe, having an upper side parallel to the longitudinal axis, and having lateral edge sides. The clamping device may have a locking element supported in the longitudinal direction on the casing unit and that can be moved to adjust the fixing position in a normal direction of the upper side against the engagement element. Positive-locking elements on the locking and engagement elements are engageable to produce a positive-locking connection in the longitudinal direction, at least some of which are disposed on an edge side of the engagement element.

The present disclosure relates to a steering column for a vehicle including an upper column on which a bracket is fixed to an outer peripheral surface of the upper column, a lower column having an inner peripheral surface supported on the outer peripheral surface of the upper column and having a telescopic driving device fixed to a side corresponding to the bracket, a connecting member coupled to the telescopic driving device so as to be movable in the axial direction during a telescopic operation, and a bending plate fixed to the bracket and having one end being bent and spaced apart from a portion fixed to the bracket and coupled to the connecting member, thereby it is possible to perform the smooth collapse operation and to reduce the number of components, assembling process and cost of the steering column of the vehicle.

The outer column has a press-fitted portion into which the inner column is press-fitted on the inner-diameter side, and an adjacent large diameter portion arranged in a location adjacent to the press-fitted portion in the axial direction and having an inner-diameter dimension larger than an inner-diameter dimension of the press-fitted portion. The inner-circumferential surface of the press-fitted portion and the outer-circumferential surface of the inner column come in contact with each other with an interference directly or via another member at only a plurality of contact locations separated in the circumferential direction. The column-side bracket is welded to an outer-circumferential surface of the adjacent large diameter portion with at least a part of the column-side bracket located on the outer-diameter side of the press-fitted portion.

A motor-adjustable steering column for a motor vehicle includes an outer casing which is held by a support unit that is attachable to a vehicle body and in which an actuator unit is received so as to be telescopically adjustable in the longitudinal direction. A steering spindle is coaxially mounted in a casing tube in the actuator unit so as to be rotatable about a longitudinal axis. An adjustment drive is disposed between the outer casing and the actuator unit and has a threaded spindle which is at least in part disposed within the actuator unit and is drivable in a rotating manner by an electric servomotor engaged in a spindle nut. In order for a compact adjustment drive which is accommodated in a protected manner to be provided, the threaded spindle is disposed at a spacing from the longitudinal axis.
