ABSTRACT:
A method and device for controlling a headrest in an automotive seat. The method and device are programmed in a central processing unit, according to which the headrest is firstly raised from the use position upon a seat back, thus making greater the rotation radius along which the headrest is rotated, and then rotatively displaced from the use position to a non-use position, in order to attain a good backward view field at the rear window of the automobile. Thus, no contact is made between the bottom surface of the headrest and upper surface of the seat back, during the displacements of the headrest between its use and non-use positions. The processing steps in the present invention involves detecting a rear-seat occupant, and separate headrest controlling by either of a driver and rear-seat occupant.
