An improved locking mechanism assembly that is within a cantilevered stowable seat for use in a vehicle in order to provide passenger seating or a space for a wheelchair or for storage of various articles. The improved locking mechanism assembly includes an aisle assembly, a wall assembly, and a transfer rod. The seat is stowed by folding the seatback flat against the seatbase, actuating the single handle located on the aisle side of the seat thereby unlocking the seatbase from its folded intermediate position and rotating the seatbase to its stowed position where it is locked in place. The stowable seat is deployed by actuating the single handle located on the aisle side of the seat assembly, thereby unlocking the seatbase from its stowed position and lowering the seatbase to its folded intermediate position where it is locked into place. The seatback is then unfolded to accommodate passengers in the deployed position.

1. A cantilevered stowable seat including at least one seat base member and at least one seatback member pivotably mounted on an axis associated with a seat framework, movable through a range of positions between a stowed position and a deployed position, said deployed position enabling an occupant
1. A cantilevered stowable seat including at least one seat base member and at least one seatback member pivotably mounted on an axis associated with a seat framework, movable through a range of positions between a stowed position and a deployed position, said deployed position enabling an occupant to sit while said stowed position accommodates a wheel chair or provides space, having said seat framework with an improved locking mechanism assembly comprising:a wall assembly removably attached to said seat framework and having a mechanism utilizing a combination of a wall cam, a wall keep, a transfer rod, and a handle to lock and/or unlock said cantilevered stowable seat in said stowed position,an aisle assembly removably attached to said seat framework and having a mechanism utilizing a combination of an aisle keep, an aisle sear, said transfer rod and said handle to lock and/or unlock the seat in the deployed position,said wall assembly and said aisle assembly being related to each other for cooperation by said transfer rod having one of its ends proximate to said aisle assembly and the other end proximate to said wall assembly,said handle associated with said transfer rod cooperating with said wall assembly and said aisle assembly thereby enabling one hand control for moving said cantilevered stowable seat from a folded intermediate position to said stowed position.2. The cantilevered stowable seat of claim 1, wherein said wall keep includes a toothed side enabling said wall keep to rotatably contact a toothed side of said wall cam to lock or unlock said wall assembly.3. The cantilevered stowable seat of claim 2, wherein said aisle keep includes a toothed side enabling said aisle keep to rotatably contact a toothed side of said aisle sear to lock or unlock said aisle assembly.4. The cantilevered stowable seat of claim 3, wherein said handle is lifted, thereby driving said aisle keep to rotate counterclockwise, and in turn driving said transfer rod, said transfer bar driving said wall keep to rotate counterclockwise and transferring motion via a tooth contact region, driving said wall cam to rotate clockwise thereby enabling a hook shaped end to release a base bar from a locked, stowed position.5. The cantilevered stowable seat of claim 3, wherein said handle is lifted, driving said aisle keep counterclockwise via a tooth contact region, driving clockwise thereby enabling a V-shaped slot to release a sliding bar from the locked, deployed position.6. The cantilevered stowable seat of claim 5, wherein said wall assembly comprises:an inner plate and an outer plate removably attached at both ends,said inner plate having a U-shaped cut out enabling a fastener to removably attach said transfer rod to said wall keep,said wall keep rotatably attached to said wall assembly at a pin with a spring lock,said wall cam rotatably attached to said wall assembly at a pin with a spring lock,said wall cam comprising a toothed side facing said wall keep, and a hook shaped end enabling a grip on said base bar for locking the seat in the stowed position.7. The cantilevered stowable seat of claim 1, wherein said aisle assembly comprises:an inner and outer plate removably attached at both ends,said inner plate having a U-shaped cut out enabling a fastener to removably associate said transfer rod to said aisle keep,said handle having a spring lock and rotatably associated at a pin, and further with said aisle keep via a aisle keep slot,said aisle keep rotatably attached to said aisle assembly at said pin,said aisle sear rotatably attached to said aisle assembly at said pin with a spring lock, said aisle sear comprising a toothed side facing said aisle keep and a V-shaped cut out,said V-shaped cut out enables said aisle sear to lock said sliding bar in position when said seatbase is in the folded intermediate or deployed positions.
