3. The motor vehicle seat arrangement according to claim 1 , wherein the releasable interlock further comprises a hinge mechanism between a middle seat back member and the armrest.
4. The motor vehicle seat arrangement according to claim 3 , wherein the hinge mechanism is formed by a strap hinge.
5. The motor vehicle seat arrangement according to claim 3 , wherein the hinge mechanism has a rod forming the tilting axis, said rod is guided in at least a first guide member at the arm rest and guided in a second guide member at the middle seat back member.
6. The motor vehicle seat arrangement according to claim 5 , wherein the first guide member and the second guide member are substantially tubular.
7. The motor vehicle seat arrangement according to claim 5 , wherein the rod is rotationally fixed to at least one of the first guide member or the second guide member and can be longitudinally moved in a direction of the tilting axis from a locking position, in which the rod is rotationally fixed to at least one of the second guide member or the first guide member, into a release position in which at least one of the second guide member or the first guide member can be tilted relative to the rod and hence the seat back can be tilted about the tilting axis.
8. The motor vehicle seat arrangement according to claim 7 , wherein the rod has an actuation end for manually moving the same in a longitudinal direction.
9. The motor vehicle seat arrangement according to claim 8 , wherein the actuation end is provided at an upper end of the seat back.
10. The motor vehicle seat arrangement according to claim 7 , wherein the rod has a radially projecting nose which is fixed in the locking position of the rod in a recess at at least one of the second guide member or the first guide member and is retracted from the recess in the release position of the rod.
11. The motor vehicle seat arrangement according to claim 7 , wherein the rod is preloaded into the locking position with a compression spring.
12. The motor vehicle seat arrangement according to claim 11 , wherein the seat back is automatically loaded into the upper armrest use position with a leg spring.
13. The motor vehicle seat arrangement according to claim 12 , wherein at least one of the leg spring or the compression spring is substantially wound around the rod.
14. The motor vehicle seat arrangement according to claim 3 , wherein the motor vehicle seat has two wing-rests, each of the two wing-rests arranged in a transverse direction at the middle seat back member.
15. The motor vehicle seat arrangement according to claim 1 , wherein the seat back can be tilted by about 180° from the lower armrest non-use position into the upper armrest use position.
16. The motor vehicle seat arrangement according to claim 1 , wherein a width of the seat back is reduced in the upper armrest use position in comparison to the lower armrest non-use position.
17. A seat arrangement, comprising:
a first motor vehicle seat, said first motor vehicle seat comprising:
a seat back, wherein the entire seat back is adapted to tilt along a first axis from a substantially upright use position into a substantially horizontal non-use position, wherein the seat back, when in the substantially horizontal non-use position, is configured be tilted about a tilting axis extending in a seat direction from a lower armrest non-use position into an upper armrest use position for forming an armrest, wherein the tilting axis is substantially perpendicular to the first axis,
the seat back further comprising:
a releasable interlock locking the seat back in the lower armrest non-use position,
wherein when the releasable interlock is released the seat back is automatically loaded into the upper armrest use position the lower armrest non-use position;
a second motor vehicle seat having a seat back arranged next to the first motor vehicle seat within a seat row,
wherein a height of the seat back of the first motor seat is substantially equal to a height of the seat back of the second motor vehicle seat.
18. The seat arrangement according to claim 17 , further comprising a third motor vehicle seat in the seat row,
wherein the first motor vehicle seat is arranged between the second motor vehicle seat and the third motor vehicle seat.
19. The seat arrangement according to claim 18 , wherein at least one of the second motor vehicle seat or the third motor vehicle seat is moveable inwards in a transverse direction in such a manner to extend at least partially into a free space that is obtained by tilting the seat back from the lower armrest non-use position into the upper armrest use position.
20. The seat arrangement according to claim 17 , wherein the first motor vehicle seat, the second motor vehicle seat, and third motor vehicle seat can be moved independently from one another in the seat direction.
