First Claim
1. A vehicle seat (25), particularly for a motor vehicle, comprising a backrest (1), a seat part (24) and a seat base (8), the backrest (1) being able to be set into a first seat back position and into a second seat back position by being pivotable relative to the seat part (24) about a first rotary spindle (3) arranged essentially transversely with respect to a main seating direction, and the seat base (8) being able to be set into a first seat base position and into a second seat base position by being pivotable relative to the seat part (24) about a second rotary spindle (10) arranged essentially transversely with respect to the main seating direction, including in the vehicle seat (25) a transmission configured in such a manner that a pivoting movement of the backrest (1) from the first seat back position into the second seat back position is coupled to a pivoting movement of the seat base (8) from a first seat base position into a second seat base position,wherein the transmission comprises a first rail (5) and a second rail (6), with a first rail position of the rails (5, 6) relative to each other corresponding to the first seat back of the backrest (1) and the first seat base position of the seat base (8) and, a second rail position of the rails (5, 6) relative to each other corresponding to the second seat back position of the backrest (1) and the second seat base position of the seat base (8), andwherein a longitudinal displacement of the rails (5, 6) relative to each other takes place between the first rail position of the rails (5, 6) and the second rail position of the rails (5, 6).

9. A method for adjusting a vehicle seat including a backrest and a seat base, the method comprising:
-
moving the backrest from a first seat back position to a second seat back position; and moving the seat base from a first seat base position to a second seat base position, wherein the moving of the backrest and the seat base occurs at the same time due to a transmission with rails that couple the backrest to the seat base and are displaced longitudinally relative to each other and the vehicle seat is in a cargo position. - View Dependent Claims (10)

11. A method for adjusting a vehicle seat including a backrest, a seat part, a seat base and a transmission, the transmission comprising a first rail and a second rail, the method comprising:
-
providing the backrest (1) being able to be set into a first seat back position and into a second seat back position by being pivotable relative to the seat part (24) about a first rotary spindle (3) arranged essentially transversely with respect to a main seating direction; providing the seat base (8) being able to be set into a first seat base position and into a second seat base position by being pivotable relative to the seat part (24) about a second rotary spindle (10) arranged essentially transversely with respect to the main seating direction; coupling a pivoting movement of the backrest (1) from the first seat back position to the second seat back position to a pivoting movement of the seat base (8) from the first seat base position into the second seat base position with the transmission; providing the transmission with a first rail position of the rails (5, 6) relative to each other corresponding to the first seat back position of the backrest (1) and the first seat base position of the seat base (8), and a second rail position of the rails (5, 6) relative to each other corresponding to the second seat back position of the backrest (1) and the second seat base position of the seat base (8); and displacing the rails longitudinally relative to each other between the first rail position of the rails (5, 6) and the second rail position of the rails (5, 6).
