Embodiment Construction

[0045] figure 1 A side view schematically shows a steering column 1 for a vehicle according to the invention in an unlocked state. The steering column 1 includes a steering shaft 2 rotatably supported by the steering column 1 . The steering column is movable horizontally and vertically along the longitudinal axis 3 of the steering column 1 . Said movement of the steering column 1 is achieved by means of an electric motor (not shown) connected to the vehicle control system. The adjustment control of the steering column 1 by means of an electric motor can for example be located on or near said steering wheel. The steering column 1 may comprise an inner column 4 and an outer column 5, wherein said outer column 5 and said inner column 4 are arranged such that they move telescopically relative to each other. The entire steering column 1 can be pivoted upwards or downwards about a pivot point 8 . exist figure 1 , the pivot point 8 is arranged in a sliding groove 9 , wherein it ...

Abstract

The invention relates to a steering column (1) for a vehicle. The steering column (1) comprises a steering shaft (2) rotatably supported by the steering column (1). The steering column (1) further comprises a first electrical motor where the first electrical motor is operably connected to the vehicle control system. The steering column (1) is arranged to be moved laterally and / or axially by the first electric motor. The steering column (1) further comprises locking means (10) arranged to lock the steering column (1) thereby preventing rotation of the steering column (1). The locking means (10) comprise a first locking member (11) attached to the steering column (1) and a second locking member (12) arranged to be attached to the vehicle chassis, where the first electric motor is arranged to move the steering column (1) to a locked position in which the first locking member (11) and the second locking member (12) are arranged to engage, thereby preventing rotation of the steering column (1).

Description

technical field [0001] The invention relates to a steering column for a vehicle. The steering column includes a steering shaft rotatably supported by the steering column. The steering column also includes a first electric motor, wherein the first electric motor is operatively connected to a vehicle control system. The steering column is arranged to be moved laterally and / or axially by the first electric motor. The steering column also includes locking means arranged to lock the steering column to prevent rotation of the steering column. The invention also relates to a method for locking a steering column and a vehicle comprising the steering column. Background technique [0002] Today, legal requirements require locking of the steering, transmission, and / or brakes to protect the car from, for example, theft or other illegal use and rollover. Today, steering columns are mainly locked using locking devices, which require space along the steering column axis. This space is...
