Patent US 4,967,178

An apparatus in which the posture of a seat for vehicles is controlled in accordance with the output from a mode selecting circuit in response to the operation of a manually operated switch composed of a mode select switch and increasing/decreasing switches, and the posture controlling direction is announced by means of displaying means. By contrast, in the second embodiment as illustrated in FIG. 2, the input to the LCD controlling circuit 260 and to the voice synthesizer 210' is dependent only upon the control mode selected by the switch 13. Thus, only the selected control mode is displayed in the audio and visual ways. Of course, the invention includes all such variations and modifications of combinations of the features disclosed for both embodiments. Such announcement is made visually and audiometrically. The mode selecting circuit supplies a signal representing the posture controlling direction to an announcing device by operation of the increasing/decreasing switches. An apparatus for controlling a seat for vehicles in which the control mode selected by an operator is displayed and the control direction of the seat is also displayed. In the case where the announcing device utilizes a voice, there are provided inhibiting means for inhibiting the voice announcing signal when the mode selecting means is continuously operated, and reset means for resetting or turning off or disabling the mode selecting device when no operation of the manually operated switch is effected for a predetermined time interval.
