The differences between the first and the second embodiment will be described.

(13) In FIG. 2A, the seat cushion arrangement 3 of the vehicle seat 1 further comprises a seat cushion tilting mechanism 15 arranged underneath the seat cushion 4. The seat cushion tilting mechanism 15 is arranged to connect the seat cushion 4 to the seat back 2, such that the seat cushion 4 changes its seat cushion angle when the seat back 2 is adjusted to the respective forward facing state or rearward facing state. The seat cushion angle of the seat cushion 4 changes to adjust the seat cushion 4 between the forward facing setup and the rearward facing setup. The seat cushion tilting mechanism 15 will be described in detail below. The seat cushion angle can be the same in both the forward facing setup and the rearward facing setup or be different.

(14) In FIG. 2A, the seat cushion 4 is arranged with a seat cushion angle relative a horizontal plane 16 as measured from an underside of the seat cushion 4. This increases the seat comfort for a user of the vehicle seat 1. Similar to FIG. 1A, the second seat back connection 11 is ready to be released from the first latch 13 and the seat back 2 is ready to be folded by pivoting the first seat back connection 10 in the rear pivoting notch 7 by moving the second end 12b of the seat back 2 forward and downward as indicated by the arrow.

(15) In FIG. 2B, the seat cushion tilting mechanism 15, connecting the seat cushion 4 and the seat back 2, has adjusted the seat cushion 4 to a horizontal position as the seat back 2 has started to fold forwards and downwards to a vertical position. As in FIG. 1B, the seat back 2 is ready to be laid horizontally over the seat cushion 4 where the second seat back connection 11 will pivotably and releasably engage with the front pivoting notch 6.

(16) In FIG. 2C, the seat back 2 lie horizontally over the seat cushion 4 and both the first seat back connection 10 and the second seat back connection 11 are pivotably and releasably engaged to the rear pivoting notch 7 and front pivoting notch 6 respectively. Similar to FIG. 1C, the seat back 2 is ready to be folded towards the rearward facing setup by moving the first end 12a of the seat back 2 upward and forward.

(17) In FIG. 2D, the seat back 2 is folded upward and forward to a vertical position and, as in FIG. 1D, the second seat back connection 11 is prepared to be releasably attached to the second latch 14 as indicated by the arrow.

(18) In FIG. 2E, the first seat back connection 10 has attached to the second latch 14 and the vehicle seat 1 has been adjusted to the rearward facing setup. The seat cushion tilting mechanism 15, connecting the seat cushion 4 and the seat back 2, has adjusted the seat cushion 4 to its seat cushion angle upon the movement of the seat back 2 such that the first seat back connection 10 attaches to the second latch 14.

(19) FIGS. 3A-3E schematically show a close-up of the seat cushion tilting mechanism 15 when the vehicle seat 1 is adjusted between a forward facing setup and a rearward facing setup according to FIGS. 2A-2E.

(20) The seat cushion tilting mechanism 15 comprises a seat cushion base 17 connected to a rear tilting arrangement 18 arranged to engage with the first seat back connection 10 of the seat back 2. The seat cushion tilting mechanism 15 is also connected to a front tilting arrangement 19 arranged to engage with the second seat back connection 11 of the seat back 2. The front pivoting notch 6 of the front seat structure member 8 and the rear pivoting notch 7 of the rear seat structure member 9 are shown in dashed lines.

(21) The rear tilting arrangement 18 comprises a rear tilting engagement member 20 movably attached to a rear tilting lever arrangement 21 rotatably connected to the seat structure 5 and comprising a transverse rear tilting lever connection 22 attached to a rear tilting frame 23 rotatably attached to the seat cushion base 17. The front tilting arrangement 19 comprises a front tilting engagement member 24 movably attached to a front tilting lever arrangement 25 rotatably connected to the seat structure 5 and comprising a transverse front tilting lever connection 26 attached to a front tilting frame 27 rotatably attached to the seat cushion base 17.

(22) The rear tilting engagement member 20 comprises a rear receiving opening 28 arranged in line with the rear pivoting notch 7 such that when the first seat back connection 10 engages with the rear pivoting notch 7, the first seat back connection 10 also engages with the rear tilting engagement member 20. The front tilting engagement member 24 comprises a front receiving opening 29 arranged in line with the front pivoting notch 6 such that when the second seat back connection 11 engages with the front pivoting notch 6, the second seat back connection 11 also engages with the front tilting engagement member 24. The first seat back connection 10 and the second seat back connection 11 are arranged to rotate the rear tilting engagement member 20 and front tilting engagement member 24 when the seat back 2 pivots in the rear pivoting notch 7 and the front pivoting notch 6 respectively.

(23) In FIG. 3A, the first seat back connection 10 of the seat back 2 is shown to be in place in the rear receiving opening 28 and in the rear pivoting notch 7. The rear tilting engagement member 20 comprises a rear tilting engagement pin 30 arranged to run in a rear tilting lever arrangement slot 31. In FIG. 3A, the vehicle seat (not shown) is in its forward facing setup. The rear tilting engagement member 20 is in this setup arranged to press on the rear tilting lever arrangement 21 by means of pressing downward and forward on a lower end 31a of the rear tilting lever arrangement slot 31. The rear tilting lever arrangement 21, being rotatably connected to the rear tilting frame 23 which in turn is rotatably attached to the seat cushion base 17, ensure that the seat cushion base 17 is arranged with the proper seat cushion angle for increased comfort.

(24) In FIG. 3B, the seat back 2 has been moved to a vertical position. The first seat back connection 10 of the seat back 2 rotating with the movement of the seat back 2, rotates the rear tilting engagement member 20. Thereby the rear tilting engagement pin 30 moves away from the lower end 31a of the rear tilting lever arrangement slot 31. This leads to that pressure is relieved from the rear tilting lever arrangement slot 31 and thereby the rear tilting lever arrangement 21. This leads to that the rear tilting frame 23 lowers the seat cushion base 17 to a horizontal position.

(25) In FIG. 3C, the seat back 2 has been lain horizontally over the seat cushion 4 and both the first seat back connection 10 and the second seat back connection 11 are pivotably and releasably engaged to the rear pivoting notch 7 and front pivoting notch 6 respectively.

(26) In FIG. 3D, the seat back 2 is folded upward and forward to a vertical position. The front tilting engagement member 24 comprises a front tilting engagement pin 32 arranged to run in a front tilting lever arrangement slot 33. The second seat back connection 11 of the seat back 2 rotating with the movement of the seat back 2, rotates the front tilting engagement member 24. Thereby, the front tilting engagement pin 32 moves towards a lower end 33a of the front tilting lever arrangement slot 33.

(27) In FIG. 3E, the second seat back connection 11 of the seat back 2 has further rotated the front tilting engagement member 24. The front tilting engagement member pin 32 presses on the front tilting lever arrangement 25 by means of pressing downward and forward on the lower end 33a of the front tilting lever arrangement slot 33. The front tilting lever arrangement 25, being rotatably connected to the front tilting frame 27 which in turn is rotatably attached to the seat cushion base 17, ensure that the seat cushion base 17 is arranged with the proper seat cushion angle for increased comfort. The vehicle seat is now in the rearward facing setup.
