ABSTRACT:
An adjusting mechanism for the back portion of a seat comprises a fixed circular flange attached to an armature of the sitting portion of the seat. The fixed flange has a cup-shaped recess and cutouts spaced at 120.degree. from one another. Each cutout contains a block with an outer toothing. The blocks are resting on block-pushing members each provided with a finger facing the mobile flange. The block-pushing members rest on a cam with three steps. The fingers of the block-pushing members cooperate with a release ring housed inside the mobile flange and having three projections provided for pushing the block-pushing members toward the center of the adjusting mechanism when the cam is pivoted in a direction for moving the back portion of the seat onto the sitting portion.
