Apparatus for determining the location and other body parameters of a seat occupant prior to deployment of an automobile airbag comprises a vector sensing device, and an electronic controller operatively coupled to the vector sensing device. The vector sensing device senses the vector extending between a fixed point of reference on an automobile and a seat occupant's eyes after the occupant assumes a sitting position. The electronic controller first determines a current location for the occupant's eyes based upon the vector signals, and the determines inflation parameters based upon the current location, anthropometric data, and a dynamic body model. The vector sensing device may comprise a manually operable light directing device pivotally mounted to the vehicle about the point of reference for directing a visible light ray at the occupant's eyes, a direction detecting sensor coupled to the light directing means for detecting the direction of the visible light ray relative to the point of reference, and a distance sensor located near the light directing means for sensing the distance between the point and the occupant's eyes. |
