A method for determining a suitable position of an adjustable component of a vehicle is provided. A 3D image of an occupant of the vehicle is captured by a 3D camera. A controller receives images from the camera and determines a first morphological characteristic of the occupant based on the 3D image, determines a second morphological characteristic of the occupant by referring to data relating the first morphological characteristic to a prediction of the second morphological characteristic, generates a 3D representation of the occupant based on the first and second morphological characteristics, and determines the suitable position of the component of the vehicle according to the 3D representation.
