Steering column for a motor vehicle

Abstract

The present invention relates to a steering column (1) for a motor vehicle, comprising an adjustment unit (2) with a steering spindle (22) mounted rotatably about its longitudinal axis (L) in a steering column jacket (21), a support unit (3) which is connectable to the body of the motor vehicle and in which the adjustment unit (2) can be mounted so as to be adjustable in the direction of the longitudinal axis (L), and a stop device (9) with a movably mounted stop element (91) which can be brought into a blocking position or a release position, wherein, in the blocking position, the stop element (91) limits the adjustment travel of the adjustment unit (2) relative to the support unit (3) and, in the release position, releases the adjustability in the direction of the longitudinal axis (L) beyond the adjustment travel, which is limited in the blocking position. In order to provide a steering column (1) with improved actuation of the stop device (9), the invention proposes that the stop device (9) has an actuation body (92) with an inert mass, said actuation body being operatively connected to the stop element (91) and being mounted movably relative to the support unit (3), wherein, in the event of a crash, the mass inertia of the actuation body (92) causes the latter to interact with the stop element (91) for movement of the stop element (91) out of the blocking position into therelease position.

Description

technical field [0001] The invention relates to a steering column for a motor vehicle comprising: [0002] an adjustment unit with a steering shaft mounted rotatably about its longitudinal axis in the sleeve; [0003] a support unit which is connectable to the body of the motor vehicle and wherein the adjustment unit is mounted so as to be adjustable in the direction of the longitudinal axis; and [0004] A stop device with a movably mounted stop element that can be brought into a blocking position or a release position, wherein, in the block position, the stop element limits the adjustment stroke of the adjustment unit relative to the support unit, and in the release position , an adjustability in the direction of the longitudinal axis beyond the limited adjustment travel in the blocking position is permitted. Background technique [0005] In order to adapt the steering wheel position to the seating position of the driver of the motor vehicle, steering columns are known i...

Problems solved by technology

However, the coupling of the stop element to the clamping device has the disadvantage that the additional adjustment travel can only be released with certainty if the control lever has actually been pivoted far enough

Moreover, the naturally frequent actuation of the clamping device requires each actuation of the stop device, which may lead to wear and functional degradation
