ABSTRACT:
The attitude (as well as the position) of a front one of onboard seats which are disposed one behind the other is controlled. To secure a space for allowing an occupant to be seated upon the rear seat, a retracting limit of an entire front seat and a rear tilting limit for its seat back are determined experimentarily to define an extent of variable attitudes. When an occupant is seated upon the rear seat, the attitude of the front seat is controlled responsive to a command to change the attitude while making a reference to the extent of variable attitudes. A retracting movement of the entire front seat which goes beyond the rear limit as well as a rearward tilting or reclining of the seat back of the front seat which goes beyond the rear tilting limit are both inhibited. In this manner, when an occupant is seated upon the rear seat, the comfortableness of such occupant is secured if the driver carelessly enters a command to change the attitude of the front seat, while preventing any oppression presented to the physical body or causing a stressed attitude of the occupant seated upon the rear seat.
