Abstract
Abstract In a motor car seat with a variable-angle backrest and having an arm support retained on the frame of the backrest which is foldable down from an essentially vertical erect non-use position in line with the backrest into a lower substantially horizontal use position. While in the use position of the arm support, the backrest maintains its alignment at least during the changing of the backrest during normal driver seat back inclination adjustment, in order to prevent the arm support from striking operating parts of the vehicle; and wherein, when the backrest is folded forwards such as to allow a passenger to exit from a rear seat, the arm support is guided to maintain its position substantially horizontal and above the shift lever arranged on the central console.
