Abstract
A reclining angle adjustment device has a pawl angularly movably mounted on a lower arm, an upper arm pivotally mounted by an angularly movable shaft on the lower arm and having an inner gear, an intermediate gear plate having an outer gear meshing with the inner gear and a rack engageable with the pawl, and a release lever angularly movably mounted on the upper arm for releasing the pawl out of mesh with the rack for roughly adjusting the angle of inclination of the upper arm. The angularly movable shaft, the inner gear, and the outer gear jointly constitute a planetary gear mechanism. A control handle is rotatably mounted on the lower arm and operatively connected through the planetary gear mechanism to the upper arm in power-transmitting relation for finely adjusting the angle of inclination of the upper arm. The planetary gear mechanism is sandwiched between the lower arm and a subplate fixed to the lower arm, the subplate having an annular flange having a central hole through which the angularly movable shaft extends. The release lever is angularly movably mounted on and around the annular flange.
