Linear guide for adjustable center armrest

Schock linear guide assembly

The more adjustment options there are around the car seat, the easier it is to find an ideal seating position. In a new city car model, the adjustable center armrest between the front seats contributes to this. Schock Metal manufactures the armrest slide in a special design as a linear guide assembly. It is characterised by a precisely defined linear movement and a perceived haptic engagement in the front and rear end positions.


To realize these special “Motion Control” running properties, Schock Metal integrated a patented friction brake developed in-house into an existing linear slide geometry. It is used to achieve a controlled movement with defined running resistance along the entire travel path. This task was solved with a mechanical device that fits exactly into the profile cross-section of the ball bearing slide. This absorbs both the friction forces in the longitudinal adjustment and the detent forces in both end positions. To transfer the running properties optimally, two slides each are fixed on a plate and delivered as a ready-to-install unit. This also makes it possible to shorten the assembly time.
