Headrest control system for motor vehicle
First Claim
1. A headrest control system for a motor vehicle equipped with a driver'"'"'s seat and at least one rear seat having an adjustable headrest mounted thereon comprising:
- driving means for moving the headrest of the rear seat between an operative position for use and an inoperative retracted position;
a first switch for actuating said driving means;
a second switch for actuating said driving means;
memory means for storing data indicative of the operative position of the headrest that is an optimum position for a given passenger;
detecting means for detecting whether said rear seat is occupied by a passenger; and
control means for controlling said driving means in response to manipulation of said first switch so that said headrest is moved in a direction which corresponds to the manipulation of said first switch, controlling said driving means on the basis of said data of the optimum position stored in said memory means to thereby move said headrest to said operative position when occupation of the rear seat by a passenger is detected by said detecting means, and controlling said driving means such that said headrest is moved to said inoperative retracted position in response to manipulation of said second switch on the condition that absence of passenger on said rear seat is detected by said detecting means.

Abstract
A headrest control system for a motor vehicle equipped with a driver'"'"'s seat and rear seats having adjustable headrests mounted thereon is disclosed which includes a driving motor for moving the headrest of the rear seat between an operative position for use and an inoperative retracted position, a first switch provided for actuating the driving motor, a second switch for actuating the driving motor, a memory for storing data of an optimum operative position of the headrest, and a sensor for detecting whether the rear seat is occupied by a passenger or not. A computerized controller is provided for controlling the driving motor in response to manipulation of the first switch so that the headrest is moved in correspondence to the manipulation of the first switch, controlling the driving motor on the basis of the data of the operative position stored in the memory to thereby move the headrest to the optimum operative position when occupation of the rear seat by a passenger is detected by the detecting means, and controlling the driving motor such that the headrest is moved to the inoperative retracted position in response to manipulation of the second switch so long as absence of passenger on the rear seat is detected by the detecting means.

10. A headrest control system for a motor vehicle equipped with a driver'"'"'s seat and a rear seat having a headrest, comprising:
-
driving means for moving the headrest at least between an optimum position for use and a fully retracted position; a first switch being provided with the rear seat for actuating said driving means; a second switch being provided with the driver'"'"'s seat for actuating said driving means; memory means for storing an optimum position data of the headrest of the rear seat; detecting means for detecting whether the rear seat is occupied by a passenger; and control means for controlling said driving means so that the headrest of the rear seat moves in accordance with an intended direction of said first switch, so that when said detecting means detects that the rear seat is occupied, the head-rest of the rear seat moves to the optimum position in accordance with the data stored in said memory means, and so that when said second switch is operated and said detecting means does not detect that the rear seat is occupied, the headrest of the rear seat moves to the fully retracted position. - View Dependent Claims (11)
