In this position, the lumbar support can optimally fulfil its purpose. As an orientation: this point will be approximately at the height of your trouser belt (this is where your upper, rear iliac crest is located). c) You can then adjust the curvature of the lumbar support. Feel your back and pay attention to how strong the support should be. a) Is the upper edge of the headrest at least level with the top of the head? b) Is the distance to the head about two to three centimetres? If you can answer yes to both questions, your headrest is correctly adjusted. The headrest is not designed to support you, but to protect you in the event of an accident. If you lean your head back while driving, this can promote tiredness and therefore microsleep. Step 6 Adjust the lumbar support (lumbar support) Step 7 Adjust the headrest Note: We often set the lumbar support too high intuitively. This means that it only fills the area of the spine above the iliac crest. If you proceed as described above, the lumbar support will automatically and effortlessly bring you more upright.
