Abstract
A seat adjusting device for adjusting an incline angle of a seat back relative to a seat cushion. A lower arm engages with a seat cushion and an upper arm engages a seat back. The lower arm has a hinge opening, and the upper arm has an opening eccentric to the hinge opening. A hinge shaft is rotatably inserted through the hinge opening and the eccentric opening and includes a convex portion engageable with the eccentric opening. An inner gear is disposed on one of the lower arm and upper arm, and an outer gear meshes with the inner gear. The outer gear has fewer teeth than the inner gear and is disposed on the other of the lower arm and upper arm. A wedge shaped member is disposed between the eccentric opening and the hinge shaft and is biased by an elastic member.
