摘要： The present invention relates to a steering column (1) for a motor vehicle, comprising a steering spindle (30) which is mounted in an inner casing tube (31) so as to be rotatable about the longitudinal axis (L) thereof, an outer casing unit (33) in which the inner casing tube (31) is held and which is directly or indirectly connectable to the body of a motor vehicle, a clamping device (4) which, in a fixing position, fixes the outer casing unit (33) relative to the inner casing tube (31) and which, in a release position, permits an adjustment of the inner casing tube (31) relative to the outer casing unit (33) at least in a longitudinal direction, wherein the clamping device (4) has at least one locking part (46) which is supported in a longitudinal direction on the outer casing unit (33) and which, in the fixing position, is connected non-displaceably in the longitudinal direction to an engagement part (34) connected to the inner casing tube (31) and which, in the release position, is released from the engagement part (34) and permits a relative movement of the inner casing tube (31) relative to the outer casing unit (33) in the longitudinal direction, wherein the inner casing tube (31) and the outer casing unit (33) are coupled by way of an energy absorption device (5) which has at least two energy absorption elements (54, 56), of which at least a first (56) or a second (54) energy absorption element can be coupled in between the inner casing tube (31) and the engagement part (34), which energy absorption element, in the coupled-in state and in the fixing position of the clamping device (4), is plastically deformed in the event of a relative displacement of the inner casing tube (31) and outer casing unit (33). In order that a smaller amount of structural space is taken up and in order to permit easier and cheaper manufacture, the invention proposes that at least the first and second energy absorption elements (54, 56) are arranged, in a radial direction with respect to the longitudinal axis, on the same side of the inner casing tube (31).

摘要： The invention relates to a steering column (1) for a motor vehicle, comprising an adjusting unit (2) with a steering spindle (22) mounted in a casing pipe (21) in a rotatable manner about the longitudinal axis (23) of the steering spindle, a support unit (3) which can be connected to the body of the motor vehicle, in which the casing pipe (21) can be received, and which has at least one clamping surface (35) facing the casing pipe (21), and a clamping device (4) which clamps the clamping surface (35) against the casing pipe (21) with a clamping force (K) in a fixing position in order to fix the adjusting unit (2) relative to the support unit (3) at least in the longitudinal direction and which releases the clamping surface (35) from the casing pipe (21) in a release position and releases an adjustment of the adjusting unit (2) relative to the support unit (3) at least in the longitudinal direction. The support unit (3) has at least one sliding surface (51) which faces the casing pipe (21) and along which the casing pipe (21) can be moved in the longitudinal direction in the release position. The aim of the invention is to provide a steering column (1) with an improved adjustability. According to the invention, this is achieved in that the sliding surface (51) is arranged on a support device (5) which presses the sliding surface (51) against the casing pipe (21) with a supporting force (S) which can be specified independently of the clamping force (K).
