2. The seat of claim 1 , wherein the first seat unit further comprises a seat body positioning member configured to be rotatably connected between the first seat unit and the stroller frame, and wherein when the seat body positioning member is coupled to the stroller frame, the seat body positioning member positions the first seat unit in the folding mode in response to folding of the stroller frame and further positions the first seat unit in a service mode in response to unfolding of the stroller frame.

3. The seat of claim 2 , wherein a first end of the seat body positioning member is connected to a first seat body of the first seat unit and wherein a second end of the seat body positioning member is configured to be coupled to a supporting member of the stroller frame.

4. The seat of claim 2 , wherein, when the seat body positioning member is coupled to the stroller, the seat body positioning member positions the first seat unit in the folding mode in response to folding of the stroller frame and further positions the first seat unit in the first unfolding mode or the second unfolding mode of the service mode in response to unfolding the stroller frame.

5. The seat of claim 1 , wherein the first seat unit further comprises a first seat back and a first seat body, the first seat back being rotatably connected to the first seat body, and the sliding slot portion being disposed on the first seat back.

6. The seat of claim 5 , wherein the seat back positioning member further comprises a rotation plate coupled to the stroller frame to which the seat is coupled, the sliding bar being connected to the rotation plate and slidably assembled with the sliding slot portion.

7. The seat of claim 6 , wherein the sliding bar is positioned at a lower area of the sliding slot portion to abut against the first seat back stayed at the first unfolding mode, and further positioned at a middle area of the sliding slot portion to switch the first seat back from the first unfolding mode to the second unfolding mode, and further positioned at an upper area of the sliding slot portion to allow the first seat back and the first seat body for being folded and switched to the folding mode.

8. The seat of claim 5 , wherein the first seat unit further comprises an infant car seat connecting member movably disposed on the first seat body and adapted to connect with an attaching member of an external infant car seat.

9. The seat of claim 8 , wherein the infant car seat connecting member is accommodated inside the first seat body when the first seat unit is in the first unfolding mode, and further protrudes from the first seat body when the first seat unit is in the second unfolding mode.

10. The seat of claim 8 , wherein the first seat unit further comprises a belting member connected to the infant car seat connecting member and the first seat back, and adapted to vary a position of the infant car seat connecting member relative to the first seat body when an inclined angle of the first seat back is changed.

11. A child stroller, comprising:
a stroller frame having two sections configured to fold and unfold relative to one another; and
a seat comprising:
a first seat unit having a sliding slot portion; and
a seat back positioning member rotatably disposed on the stroller frame, the seat back positioning member comprising a sliding bar adapted to slide inside the sliding slot portion as the stroller frame is folded and unfolded to switch the first seat unit into one of a first unfolding mode, a second unfolding mode and a folding mode.

13. The child stroller of claim 12 , wherein the stroller frame further comprises a locking member disposed between the front leg member and the handle member, the locking member being configured to constrain a position of the front leg member relative to the handle member to steady the stroller frame in one of the folding mode and a service mode.

14. The child stroller of claim 12 , wherein the handle member is disposed above the front leg member and the rear leg member, the front leg member is set as a front section of the two sections, the handle member and the rear leg member are set as a rear section of the two sections.

15. The child stroller of claim 12 , wherein the first seat unit is rotatably disposed on the front leg member, the first seat unit further comprises a seat body positioning member rotatably connected between the first seat unit and the stroller frame, the seat body positioning member is rotatably connected to the supporting member, the seat back positioning member is rotatably disposed on a connection position between the front leg member and the handle member.
