とする自動車シートのランバーサポート装置。 A sector gear integrated with the operating section, a torsion bar attached to the shaft that transmits the rotational force of the sector gear to the lumbar support and urges the sector gear in a reverse direction, and converts the rotational force of the sector gear into a force in the vertical direction. a connecting rod that transmits the torsion bar and is provided between the torsion bar and the sector gear; a stopper that prevents the sector gear from reversing and is attached so as to be retractable in a disengaged direction; a lock-off plate that moves the stopper in the disengagement direction when the stopper is in the disengaged direction and moves the stopper in the engagement direction when the forward rotation angle of the sector gear is at a minimum; The distance between the rotation center of the sector gear and the connecting rod between the forward rotation angle and the maximum forward rotation angle of the sector gear is the same, and when the forward rotation angle of the sector gear reaches the maximum, the connection position of the sector gear and the connection rod is set. A lumbar support device for a car seat, characterized in that the heights of the lumbar supports are the same.
