The invention relates to a method for determining the current position (A, B, C, D) of a head ( 9 ) of an occupant ( 8 ) in the passenger compartment ( 2 ) of a motor vehicle ( 1 ), said head moving toward an automatic dynamic disabling zone ( 6 ) in front of an airbag module ( 5 ). To this end, the invention makes use of the idea that the best position for a measurement with regard thereto is the point in space where the ideal direction of movement ( 14 ) of the head ( 9 ) is perpendicular to an ideal line of sight ( 17 ) of the camera ( 160 . The measurement is then preferably carried out when the geometric center ( 10 ) of the head ( 9 ) crosses this point. In a preferred embodiment, the calculation of the actual movement vector of the head ( 9 ) is taken as a basis, said head being preferably perpendicular in a current line of sight ( 18 ) of the camera ( 16 ). The invention advantageously increases the potential for protecting an occupant ( 8 ) in a motor vehicle ( 1 ). It is thus suited, in particular, for use in occupant protection systems of modern motor vehicles ( 1 ). |
