Title: Device to measure the rotational position of a steering wheel

Abstract: A device is provided to detect the rotational position of a steering wheel. A rotating steering shaft connected to the steering wheel is coaxial with respect to a non-rotating steering column. On one surface of the steering column facing the steering shaft, there is an electrical resistance sheet that extends in the peripheral direction of the steering column. Fastened to the steering shaft are at least two wipers associated with the resistance sheet, such that at all times at least one wiper is in contact with the resistance sheet in a position defined by the rotational position of the steering shaft. Preferably, there are exactly three wipers that correspond to the same resistance sheet that are offset from one another by about 120 degrees.
