<p>Provided is a seat adjustment device for adjusting the pivoting angle formed by a first seat member and a second seat member which are connected by a hinge shaft. A seat adjustment device is provided with a rotation adjustment mechanism, an arm section, and a connection mechanism. The hinge shaft connects at a first connection point the first seat member and the second seat member. The arm section and the connection mechanism are connected at a second connection point. The positions of the axes of the first connection point, the second connection point, and a pivoting section are set in such a manner that, when a load is applied to the front end of either the first seat member or the second seat member, the distance from the second connection point to the axis of the pivoting section is less than the distance from the first connection point to the second connection point with respect to the direction perpendicular to the line of action of a load applied to the second connection point.</p> |
