ABSTRACT:
A vehicle seat back support and, more particularly, a seat back support with provision for selective adjustment of the angular position between the seat cushion and the seat back. A seat cushion mounting member has a toothed sector in its upper, rearward edge portion. Below the toothed sector, a rotatable support shaft is mounted which includes an eccentric portion on which a seat back mounting member is pivotally mounted. The seat back mounting member includes a toothed portion adapted to engage or mesh with the toothed sector of the seat cushion mounting member. An actuation lever is attached to the rotatable support shaft to move the eccentric portion upward by rotation of the shaft. Resultantly, the seat back mounting member is moved upward and its toothed portion is disengaged from the toothed sector, thereafter permitting the seat back to be angularly adjusted with respect to the seat cushion.
