A seat assembly for supporting an occupant above a floor of an automotive
vehicle including a cushion and a riser coupled between the floor of the
vehicle and the seat cushion for allowing manual lateral displacement of
the seat cushion within the vehicle between a plurality of lateral
positions. The seat cushion is pivotally coupled to front legs for
movement between a seating position and a forwardly dumped position. The
front legs are interconnected to a foot bracket. The foot bracket
includes a hook portion slidably engaged with a rod fixedly secured to
the floor of the vehicle for manual movement of the seat cushion between
the plurality of lateral positions. A cinching hook is pivotally coupled
to the foot bracket for movement between locked and unlocked positions.
In the locked position, the cinching hook clamps the rod between the hook
portion and the cinching hook for resisting lateral displacement of the
seat cushion along the rod. In the unlocked position, the cinching hook
is subsequently disengaged from the rod to allow lateral displacement of
the seat cushion along the rod. A link extends between the seat cushion
and the cinching hook for moving the cinching hook between the locked and
unlocked positions in response to movement of the seat cushion between
the locked and the unlocked positions.
