A variable displacement seating assembly incorporates at least first and second pivotable seat frames. The first seat frame includes a male seat connector. The second seat frame is arranged adjacent the first seat frame, and includes a female seat connector receiving the male seat connector of the first seat frame. The first and second seat frames are operatively interconnected for simultaneous pivoting movement between a stowed position and a deployed position. In the deployed position of the first and second seat frames, the male and female seat connectors are disposed for sliding vertical movement of one seat connector relative to the other, such that the first and second seat frames are independently vertically displaceable upon an impact force acting against the seat assembly.
