A stroller comprises a support frame and a handle, and a seat assembled between the support frame and the handle. A front leg is coupled with a rear leg via a first pivot link, and a side segment of the handle is movable relative to the front and rear leg. The seat has a front portion pivotally connected with the front leg, and a rear portion pivotally connected with the side segment of the handle. The side segment is in stable abutment against a contact region of the support frame adjacent to the first pivot link for supporting the seat. For folding the stroller, the handle is moved in a first direction that raises the side segment above the support frame for displacing the contact region of the support frame in a forward direction to a disengaged position out of reach for the lower end portion of the side segment.

1. A stroller apparatus comprising: a support frame and a handle defining two lateral sides, wherein at least one of the two lateral sides has a front leg and a rear leg of the support frame coupled together via a first pivot link, and a side segment of the handle movable relative to the front and rear leg; anda seat assembled between the two lateral sides, wherein the seat has a front portion connected with the front leg via a second pivot link and a rear portion connected with the side segment of the handle via a third pivot link,wherein a lower end portion of the side segment is in stable abutment against a contact region of the support frame adjacent to the first pivot link for supporting the seat. 2. The stroller apparatus according to claim 1, wherein a latch mechanism between the support frame and the handle is operable to fasten the handle with the support frame when the lower end portion of the side segment is in abutment against the support frame. 3. The stroller apparatus according to claim 2, wherein the latch mechanism includes an anchor element provided on the support frame, and a locking element operable to engage with the anchor element. 4. The stroller apparatus according to claim 3, wherein the locking element is pivotally mounted with the side segment of the handle. 5. The stroller apparatus according to claim 3, wherein the anchor element includes a pivot element coupling a first top portion of the front leg with a second top portion of the rear leg. 6. The stroller apparatus according to claim 5, wherein the locking element is operable to engage with the pivot element through a gap between the first top portion and the second top portion. 7. The stroller apparatus according to claim 6, wherein the side segment of the handle is provided with a cover sleeve adapted to occlude at least partially the gap between the first top portion of the front leg and the second top portion of the rear leg. 8. The stroller apparatus according to claim 1, wherein the lower end portion of the side segment is in abutment against a first top portion of the front leg and a second top portion of the rear leg for supporting the seat. 9. The stroller apparatus according to claim 1, wherein the lower end portion of the side segment is kept in abutment against the contact region of the support frame by a weight load of the seat. 10. The stroller apparatus according to claim 1, wherein the seat defines a seating plane that is inclined from a horizontal direction when the lower end portion of the side segment is in abutment against the contact region of the support frame. 11. The stroller apparatus according to claim 1, wherein the support frame further includes a first linking element fixedly coupled with the rear leg, a second linking element coupling the first linking element with the lower end portion of the side segment, and a third linking element coupling the front leg with the second linking element. 12. The stroller apparatus according to claim 11, wherein the handle is operable to raise the side segment above the support frame by an amount of displacement for moving the contact region of the support frame in a forward direction to a disengaged position out of reach for the lower end portion. 13. The stroller apparatus according to claim 12, wherein the requisite amount of displacement further includes a forward rotation of the handle about the third pivot link relative to the seat. 14. A method of operating a stroller apparatus, wherein the stroller apparatus comprises a support frame including at least a front leg and a rear leg coupled with each other via a first pivot link, a handle having a side segment, and a seat coupled with the front leg and the side segment respectively via a second and third pivot link, the method comprising: providing the stroller apparatus in an unfolded state, in which a lower end portion of the side segment is kept in stable abutment against a contact region of the support frame adjacent to the first pivot link by a weight load of the seat;moving the handle in a first direction that raises the side segment above the support frame for displacing the contact region of the support frame in a forward direction to a disengaged position out of reach for the lower end portion of the side segment; andmoving the handle in a second direction that collapse a rear side of the seat downward. 15. The method according to claim 14, wherein the lower end portion of the side segment is kept in stable abutment against a first top portion of the front leg and a second top portion of the rear leg when the stroller apparatus is in the unfolded state. 16. The method according to claim 14, wherein the step of moving the handle in a first direction that raises the side segment above the support frame further includes rotating the handle in a forward direction relative to the seat. 17. The method according to claim 14, wherein the stroller apparatus in the unfolded state comprises a latch mechanism that locks the handle with the support frame. 18. The method according to claim 17, further comprising the step of unlocking the latch mechanism before moving the handle in the first direction that raises the side segment above the support frame. 19. The method according to claim 18, wherein the step of unlocking the latch mechanism comprises disengaging a movable locking element from an anchor element fixedly provided on the support frame. 20. The method according to claim 14, wherein the front leg and the rear leg are coupled with each other via a plurality connecting links that fold upon one another in at least partially overlapping positions to reduce a distance between the front leg and the rear leg when the handle is moved in the second direction.
