The outer column 25 has a front-side small-diameter tubular portion 37 into which the inner column 24 is press fitted. The inner-circumferential surface of the front-side small-diameter tubular portion 37 and the outer-circumferential surface of the inner column 24 come in contact with an interference fit at only a plurality of contact locations separated in the circumferential direction. At least one location in the axial direction of the column-side bracket 26 is welded to the outer-circumferential surface of the front-side small-diameter tubular portion 37 at only two weld locations that are close in the circumferential direction.

The present invention relates to a modular energy absorption device (9) comprising: a support (91) having fastening portions (81) forming single fastening points for fastening said device to a steering column, a deforming member (94) securely connected to the support, an absorber (93) coiled around the deforming member and fitted securely at each of its ends to the support, a coupling member (96) formed of a part separate from the support and having a first side securely connected to the absorber and a second side having at least a first engaging shape (96a),
said device being designed such that the exertion of forces in opposite directions on the support and on the tooth, respectively, brings about stress on the coiled portion of the absorber, tending to deform the latter.

A column jacket includes a hollow outer jacket having a pair of clamped portions disposed to sandwich a slit between the clamped portions and a tubular inner jacket having, in an area where the inner jacket is fitted in the outer jacket, an elongated hole extending in an axial direction. A clamping mechanism clamps the pair of clamped portions with a pair of side plates of a fixed bracket. The elongated hole is disposed on any one of a first side and a second side, in the lateral direction, of a vertical plane passing through a central axis of the inner jacket, at a position other than on a straight line that extends in a vertical direction through the central axis.

The disclosure relates to a mounting unit for mounting a steering shaft in an associated mounting sleeve, which unit comprises a mounting body, at least two first mounting arms and at least two second mounting arms for radially supporting the mounting unit within the mounting sleeve. A roller bearing is provided on a radially inner side of the mounting body, the mounting body forming an outer ring of the roller bearing on which rolling elements roll. In addition, the disclosure relates to a steering column assembly in which a steering shaft is mounted radially within a mounting sleeve by such a mounting unit.

An energy absorption device for a vehicle steering column comprising a metal band and an adjustable deformation unit through which the metal band extends. The deformation unit is a rotatable hollow roller having a first contact surface inside the hollow roller that is separated from an outer contact surface by an outlet slot. The metal band passes through an inlet slot into the interior of the roller, and then through the outlet slot leaves the roller, in a manner that that said metal band is entirely deformed along an S-shaped curve.

A steering column device includes an inner tube, a housing, and a lock mechanism configured. The lock mechanism includes a first engagement member, a second engagement member, a first urging member, a second urging member, a cam member configured to rotate about a rotation axis extending in a direction in which the first urging member and the second urging member are arranged such that the second urging member serving as a follower is moved in the direction in which the first urging member and the second urging member are arranged to change a magnitude relationship between an urging force of the first urging member and an urging force of the second urging member, and an operation lever configured to operate the cam member.

The present disclosure relates to the technical field of vehicle steering, and provides an electrically adjustable steering column and an electric power steering system. The electrically adjustable steering column includes: a telescopic component including a first steering shaft and a first protective jacket sleeved on the first steering shaft; a drive component including a drive bracket disposed on an outer wall of the first protective jacket, wherein a main body of the drive bracket is provided with a first energy absorption slot extending in an axial direction; an energy absorption component including a first bolt passing through the first energy absorption slot and extending into the first protective jacket, wherein the first bolt is fixedly connected to the first protective jacket and in a sliding fit with the first energy absorption slot; when in a use stage, the first bolt is maintained at a head end of the first energy absorption slot, and the drive component is capable of driving the telescopic component to expand and contract through the drive bracket; when in a collapse and energy absorption stage, the telescopic component collapses and drives at least the first bolt to slide in the first energy absorption slot. The present disclosure realizes a maintaining function during telescopic adjustment and an energy absorbing function during collision and collapse mainly by the bolt, thereby simplifying the structure and reducing the cost.

A steering column assembly includes an upper jacket. The steering column assembly also includes a lower jacket that the upper jacket is telescopingly coupled to. The steering column assembly further includes an energy absorbing strap operatively coupled to the upper jacket and the lower jacket, the energy absorbing strap having a first leg, a second leg and a U-shaped portion connecting the first leg and the second leg. The steering column assembly yet further includes a pin located within a slot defined by the first leg and the second leg of the energy absorbing strap.

A steering column for a motor vehicle may include an inner casing in which a steering spindle is mounted rotatably about a longitudinal axis that extends in a longitudinal direction and is received in an outer casing in a slidingly adjustable manner in the longitudinal direction. A pretensioning apparatus may have a pressure piece that can be braced from an outside in a tensioning direction transversely to the longitudinal axis against the inner casing. The pressure piece is held in the longitudinal direction on the outer casing and is supported against a fixing element counter to the tensioning direction. The fixing element is fixed in a recess of the outer casing. The fixing element has a forming means that is plastically furrowed into the recess, and/or the recess has a forming means that is plastically furrowed into the fixing element.

A steering column for a motor vehicle may include an adjusting unit in which a steering spindle is mounted so as to be rotatable about a longitudinal axis extending in a longitudinal direction, a holding unit in which the adjusting unit is adjustably held, and a fixing device with a first clamping device and a second clamping device for the releasable fixing of the adjusting unit relative to the holding unit. The clamping devices are operatively connected to a clamping lever that can be selectively brought into a fixed position or into a released position. The clamping devices may be operatively arranged in parallel.
