A collapsible steering column assembly includes a shroud comprising an outer tube that supports a steering wheel through a bearing and an inner tube that is fixed to a part of the vehicle, the column assembly being able to collapse telescopically by the outer tube moving over the inner tube, the assembly further including an energy absorbing strap that is fixed to the inner tube and a plough which is fixed to the outer tube, whereby in use the assembly is so arranged that upon a telescopic collapse the relative movement between the inner tube and the outer tube forces a part of the plough through the strap to progressively peel away a part of the strap from the remainder of the strap.

A motor-adjustable steering column for a motor vehicle has an outer casing which is held by a support unit that is attachable to a vehicle body. An actuator unit is received in the outer casing to adjust in the longitudinal direction. A steering spindle is coaxially and rotatably mounted in a casing tube in the actuator unit. An adjustment drive and an energy absorbing installation are disposed between the outer casing and the actuator unit. The adjustment drive has a spindle mechanism with a threaded spindle which is rotatably drivable by an electric servomotor engaged in a spindle nut. The energy absorbing installation has at least one energy absorbing element at least indirectly disposed between the spindle nut and the actuator unit. The spindle nut or the threaded spindle has at least one forming element which operatively engages with the energy absorbing element and is plastically deformable.

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.

A steering column for a motor vehicle may include a holding device that is connectable to a chassis of a motor vehicle as well as a shifting device, which in the event of a crash is displaceable relative to the holding device along a displacement axis. The shifting device may be configured to receive a steering spindle. The steering column may further include a deformation element that is connected to the holding device and to the shifting device via a respective connection portion with respective fastening means. At least in some examples, the deformation element may include a deformation portion that is deformed about a deformation axis during displacement of the shifting device relative to the holding device. The deformation axis may be oriented substantially parallel to a surface normal of at least one connection portion in a center of the associated fastening means.

A steering column assembly includes a first energy absorption strap and an energy absorption strap mounting assembly coupled to a jacket assembly. The energy absorption strap mounting assembly includes an engagement surface and at least one standoff. The at least one standoff extends from at least one of the first energy absorption strap and the engagement surface. The at least one standoff spaces the first energy absorption strap from the engagement surface in an assembled condition. The spacing defines a receiving area configured to receive a second energy absorption strap therein.

In a steering device according to an aspect of the present disclosure, a driven cam includes a lock position restriction surface with which a cam portion of a drive cam engages in a locked state and a release position restriction surface that is provided to be separated front the lock position restriction surface in a bolt circumferential direction and that engages with the drive cam in the bolt circumferential direction in an unlocked state. The cam portion includes a sliding surface that faces the driven cam in the unlocked state and a flank surface that faces the release position restriction surface in the bolt circumferential direction. The angle of the flank surface with respect to the bolt circumferential direction is smaller than the angle of the release position restriction surface with respect to the bolt circumferential direction.

A steering device includes a bracket and right and left bolts. The bracket includes right and left side plates supporting a steering column from both sides, respectively, in a widthwise direction, and right and left flanges extending outwardly in the widthwise direction from respective upper ends of the right and left side plates. The bolts fasten the flanges to a mount surface of a vehicle body. The flanges include respective right and left internal protrusions protruding toward the mount surface from respective flange surfaces, which face the mount surface. The internal protrusions are located forwardly in a vehicle body back-and-forth direction relative to tightened positions of the bolts, and are located near respective internal edges of the flanges in the widthwise direction.

A steer-by-wire steering system for a motor vehicle is presented, having a steering means to be held by the driver, a bearing device and an electric steering means actuator. The bearing device has a first sleeve element and a second sleeve element, which are connected to one another to be telescopic along an axial direction of the sleeve elements. The bearing device has a fastening element, which is fixedly connectable to a body of the motor vehicle, wherein the second sleeve element is fixedly mounted on the actuating element and wherein the steering means and the steering means actuator are mounted on the first sleeve element such that they are immovable in relation to the first sleeve element in the axial direction.

A drive carriage of a vehicle steering system positioned between a movable tube and a drive member, having an attachment zone intended to cooperate with the movable tube, the attachment zone making a fixation of the movable tube on the drive carriage when a force exerted on the attachment zone is below a first predetermined threshold and a movement of the movable tube relative to the drive carriage when the force exerted on the attachment zone exceeds the first predetermined threshold, the drive carriage comprises a coupling zone intended to cooperate with a cover part making the fixation of the cover part on the drive carriage when a force exerted on the coupling zone is below a second predetermined threshold and a movement of the cover part relative to the drive carriage when the force exerted on the second coupling zone exceeds the second predetermined threshold.

A steering column may include an actuating unit in which a steering shaft is mounted rotatably, a holding unit that is connectable to a body of a motor vehicle and that adjustably supports the actuating unit, a locking element that is coupled movably to the holding unit for axial locking of the actuating unit, a spring element that exerts a prestressing force on the locking element, a securing element for fixing the spring element, and a counterbearing. The locking element, the securing element, and the counterbearing may form a three-point arrangement in which the spring element is fixed. The spring element may be supported on one side on the locking element and on the other side on the counterbearing. The securing element may be arranged between the locking element and the counterbearing and may prestress the spring element.
