A three-wheeled stroller has a kickstand movable between a retracted position and a deployed position. When deployed, the kickstand has a pair of downwardly extending legs on either side of the front wheel to help prevent a tipping condition when an occupant enters or exits the stroller. Either a foot-operated actuator or a hand-operated actuator may be used to remotely operate the kickstand. In the case of a foot-operated actuator, stepping on a foot-operated brake bar can both operate the kickstand and immobilize one or more rear wheels to brake the stroller.

What is claimed is: 1. A three-wheeled stroller comprising: a stroller frame, a front wheel and a pair of rear wheels; and a kickstand movable between a retracted position and a deployed position, the kickstand comprising at least one leg extending downwardly on one side of the front wheel in a front view of the stroller when the kickstand is in the deployed position, wherein the kickstand is remotely operated by an actuator. 2. The three-wheeled stroller according to claim 1, wherein kickstand comprises first and second legs, one leg on either side of the front wheel, in a front view of the stroller. 3. The three-wheeled stroller according to claim 2, further comprising a cable operatively connected to the kickstand and to the actuator, and configured to adjust the kickstand from at least one of the retracted and deployed positions to the other of the retracted and deployed positions. 4. The three-wheeled stroller according to claim 2, wherein the kickstand comprises a rotatably mounted rod to which the first and second legs are attached. 5. The three-wheeled stroller according to claim 2, wherein the kickstand comprises: at least one torsion spring configured to bias the first and second legs towards the retracted position. 6. The three-wheeled stroller according to claim 2, wherein the kickstand further comprises at least one lever arm operatively connected to the legs, activation of the lever arm causing the legs to move from the retracted position to the deployed position. 7. The three-wheeled stroller according to claim 2, wherein the kickstand comprises at least one projecting tab configured to prevent over-rotation of the legs, when the legs are moved from the retracted position to the deployed position. 8. The three-wheeled stroller according to claim 2, further comprising a foot-operated actuator configured to adjust the kickstand between the retracted position to the deployed position. 9. The three-wheeled stroller according to claim 2, further comprising a cable operatively connected to the foot-operated actuator and to the kickstand, wherein stepping on the foot-operated actuator causes the cable to pull the kickstand from the retracted position into the deployed position. 10. The three-wheeled stroller according to claim 2, comprising a hand-operated actuator configured to adjust the kickstand between the retracted position and the deployed position. 11. The three-wheeled stroller according to claim 2, wherein the hand-operated actuator is provided with a lock release member which, when activated, causes the kickstand to return to the retracted position from the deployed position. 12. The three-wheeled stroller according to claim 3, further comprising an adjustable screw operatively connected to the cable and configured to determine a vertical position of the legs of the kickstand, when in the deployed position. 13. The three-wheeled stroller according to claim 3, wherein the kickstand comprises a rotatably mounted rod to which the first and second legs are attached. 14. The three-wheeled stroller according to claim 13, wherein the kickstand further comprises first and second torsion springs coaxially mounted on the rod and configured to bias the first and second legs towards the retracted position. 15. The three-wheeled stroller according to claim 13, wherein the kickstand further comprises at least one lever arm operatively connected to the rod, and the cable is attached to the lever arm. 16. The three-wheeled stroller according to claim 15, wherein the kickstand further comprises at least one projecting tab attached to the rod and configured to prevent over-rotation of the rod, when the kickstand is moved from the retracted to the deployed position. 17. The three-wheeled stroller according to claim 8, wherein the foot-operated actuator is also configured to immobilize at least one of the rear wheels. 18. The three-wheeled stroller according to claim 8, further comprising an actuator locking assembly mounted on an axle connecting the rear wheels. 19. The three-wheeled stroller according to claim 9, further comprising an adjustable screw operatively connected to the cable and configured to determine a vertical position of the legs of the kickstand, when in the deployed position. 20. The three-wheeled stroller according to claim 18, wherein the actuator locking assembly comprises: a fixed member mounted on the axle; and a movable member mounted on the fixed member and configured to move relative to the fixed member, a portion of the movable member being provided with: an initial abutment surface, a concave receiving portion adjacent to the initial abutment surface, the concave receiving portion being configured to receive at least a portion of the foot-operated actuator, and a release surface which, when pushed, causes the movable member to move relative to the fixed member in a direction of the axle. 21. The three-wheeled stroller according to claim 20, wherein the movable member is spring-loaded. 22. In a three-wheeled stroller having a front wheel and a pair of rear wheels, the improvement comprising: a cable-operated kickstand adjustable between a retracted position and a deployed position, the kickstand comprising a pair of legs extending downwardly on either side of the front wheel in a front view of the stroller, when the kickstand is in the deployed position. 23. The three-wheeled stroller according to claim 22, wherein the improvement further comprises: a foot-operated actuator connected to the kickstand and configured to both adjust the kickstand between the retracted position and the deployed position, and immobilize at least one of the rear wheels. 24. The three-wheeled stroller according to claim 22, wherein the improvement further comprises: a hand-operated actuator connected to the kickstand and configured to adjust the kickstand between the retracted position and the deployed position. 25. A method of deploying a kickstand that helps prevent tipping of a three-wheeled stroller having a front wheel and a pair of rear wheels, the method comprising: stepping on a brake bar to thereby cause a cable to pull on a lever operatively connected to a pair of retracted legs of the kickstand, whereby the legs move downward into a deployed position and, simultaneously, at least one rear wheel of the three-wheel stroller is immobilized.
