Abstract: An apparatus for applying an auxiliary force in a motor vehicle steering unit may include a driving worm that is connectable to an electric motor and applies an auxiliary force on the motor vehicle steering unit through a worm wheel. The driving worm may be housed in a roller bearing. The roller bearing can be pivoted about a pivoting axis defined by a pivot element outside the roller bearing.

Abstract: A vehicular headlight, in particular an automobile headlight, including a reflector (1) having a reflecting surface, is capable of illuminating a flat target surface to be illuminated with a desired light distribution by optimal utilization of the light source of the headlight. Therefore the optically effective surface of the headlight is characterized by point asymmetry in substantially all planes cutting said reflecting surface. This can be realized by using a method for producing said optical surface comprising the steps of: mathematically representing said surface by creating a spline from bivariate tensor product of polynomials; deriving mathematical data in computer input format from said mathematical representation; and inputting said data to a computer for controlling an apparatus by which the mathematical representation of said optical surface is reproduced in physical form.
