Title: STEERING COLUMN HAVING AN ELECTRO-MECHANICAL FIXING DEVICE
Abstract:
The invention relates to a steering column (1) for a motor vehicle, which steering column can be adjusted in the longitudinal direction (12) thereof and/or in the height direction (11) thereof, comprising a jacket tube (5), which rotatably supports a steering shaft (2), a guide bracket (6), which can be directly or indirectly connected to the body of the motor vehicle and has two side jaws (18, 19), between which the jacket tube (5) is arranged, and an electro-mechanical fixing device (13), in the unlocked position of which the jacket tube (5) can be adjusted relative to the guide bracket (6) in the longitudinal direction (12) and/or in the height direction (11) of the steering column (1) and in the fixing position of which the set position of the jacket tube (5) relative to the guide bracket (6) is fixed. The fixing device (13) comprises a clamping bolt (15), which extends through the side jaws (18, 19) of the guide bracket (6) and can be rotated about the axis thereof by means of an electric motor (17) during the opening and closing of the fixing device (13), a reciprocating mechanism (16), and a support bearing. The side jaws (18, 19) of the guide bracket (6) and the jacket tube (5) are arranged between the reciprocating mechanism (16) and the support bearing. The electric-motor (17) acts on the clamping bolt (15) by means of a pivotably mounted lever (23). A sensor (28, 48) is provided, which is designed to detect the position of the lever (23).
