13. A method of folding a vehicle seat having an upper seat and a lower seat pivotably coupled together with a recline mechanism and wherein said lower seat includes at least one leg and at least one latch mechanism and wherein said lower seat is pivotably coupled to a vehicle with a pivot attachment, said method comprising:
-
pulling a first actuator to release the latch mechanism; pulling the seat rearward about the pivot attachment with said first actuator and wherein as said seat is pulled rearward, a recline release cable is automatically pulled by the seat'"'"'s movement; continue pulling said seat rearward until said recline release cable disengages the recline release mechanism and the lower seat half and the upper seat half fold together and wherein as said seat is pulled rearward, a leg fold cable having a pivot end coupled to said pivot attachment and a leg end coupled to said legs stays stationary at said pivot end while said leg end extends in an arcuate motion about said pivot attachment and causes said legs to fold inward; and release said first actuator and placing said seat within a seat well on the vehicle. - View Dependent Claims (14)

15. A method of folding a vehicle seat into a seat well on a vehicle with a single motion, said vehicle seat having an upper seat and a lower seat pivotably coupled together with a recline mechanism and wherein said lower seat includes at least one leg and at least one latch mechanism in a latched position with the seat is in an upright position and wherein said lower seat is pivotably coupled to a vehicle with a pivot attachment, said method comprising:
-
by a single action, pulling a first actuator in a direction away from the rear of the upper seat, causing the latch mechanism to release and allowing the seat to pivot rearward about the pivot attachment and wherein as the seat pivots about the pivot attachment, a recline release cable is automatically pulled by the seat'"'"'s movement and disengages the recline release mechanism causing the lower seat half and the upper seat half fold together into a clamshell position and wherein as the seat is pulled rearward, a leg fold cable extending between said pivot attachment and said legs automatically causes said legs to fold inward; and upon releasing the first actuator, the seat is configured to fit within a seat well on the vehicle. - View Dependent Claims (16)
