A seat back cushion support presenting device for use in a foldable
vehicle seat moves a cushion support member from a position within the
seat back frame to a position extended from the seat back frame such that
the entire cushion is presented. A pair of presenting members, each
including a side bolster support portion, are provided in overlapping
arrangement for translation along a presenting device support member and
rotation with respect to a cushion support member such that as an
activation member moves the presenting members together, the cushion
support member is extended along with the side bolster support portions.
