ABSTRACT:
A belt tension adjustment mechanism having a pivoting pulley support plate adapted to cooperate with a pivoting ratchet plate. The pulley support plate directly or indirectly anchors a belt to be tensioned. A tension spring is associated with the ratchet plate to bias the ratchet plate towards a position of increased belt tension. The ratchet plate includes a teeth and pawl arrangement for preventing the ratchet plate from spontaneous rotation to a position of reduced belt tension.
