To be upholstered and retractable. This training causes very significant costs and is also rejected because of the cumbersome handling in practice. It is also already known to produce, in particular, control buttons on the dashboard or switch lever buttons from flexible material, e.g. polyethylene ™ or polyvinyl chloride plastics ^ or rubber, ■ so that they are elastic and have a shock-reducing effect. experience has shown that only the "use of such flexible materials not" from '.
