ABSTRACT:
A vehicle seat support assembly including an overcenter locking mechanism with a flexible metallic band wrapped about a floor mounted support tube and connected to a seat support frame pivotal on the tube such that tensioning of the band in an overcenter manner selectively prevents pivotal seat frame movement. A locking member of the mechanism is pivotally supported on the frame for rotation about a first axis and pivotally supports one end of a link about a movable second axis with another end of the link connected to one end of the band. In a locking position of the mechanism, the ends of the link are overcenter with respect to the first axis to provide the band tensioning and consequent prevention of seat frame pivoting. A curved intermediate portion of the link between its ends extends around a pin that supports the locking member on the frame. One preferred embodiment has its link provided with upper and lower link portions between which the other end of the band extends for connection to the seat frame, and a tensioner is provided for clamping a bight section of the band to provide proper band tension in the locking position. In another preferred embodiment, the link extends through an opening in the other band end and is connected to the seat frame by a tensioner having a pivotal lever. Both preferred embodiments have a manually actuated handle that moves the locking member and concomitantly moves a cooperable pawl on the seat frame into and out of engagement with the support tube. A mounting and thrust plate construction cooperates with the upper tube end in mounting the seat frame and limiting pivotal seat frame movement.
