SEAT RECLINER MECHANISM WITH FOLD-FLAT FEATURE

摘要

A vehicular seat assembly (14) includes a backrest (16) which can be reclined between maximum upright (22) and maximum rearward (20) conditions. The backrest (16) can also be rotated forwardly to a fold-flat condition (24). A rotary recliner mechanism (26) controls reclining motion of the backrest (16). A dump latch (44) is operatively associated with the rotary recliner mechanism (26). The dump latch (44) is automatically actuated by movement of the seat backrest (16) past its maximum upright condition (22). The dump latch (44) is controlled by a trigger (50) which interacts with a cam (60) on a base plate (28) of the rotary recliner mechanism (26). A biasing member (54) automatically resets the trigger (50) when the backrest (16) is returned to its maximum upright position (22). The dump latch (44) and biasing member (54) are carried on a toothed top plate (32) that is formed integrally with the rotary recliner mechanism (26).
