  • Patent number: 4161892
    Abstract: An anatomically shaped steering-wheel for motorcars and motor boats is disclosed, in which, in the steering-wheel areas adjacent to the spoke roots a hollow space is provided on the spoke root area, which is followed by a swelling of the inner surface of the rim, whereas an indentation is formed on the outer rim periphery to stop the slippage of the hand by providing an abutment or the hand's edge and the small finger. A safe and reliable grip of the steering-wheel is thus provided under any driving positions, such as sharp road bends, mountain driving and the like.
