a stroller frame comprising a pair of laterally opposed legs, a first end of each leg being movably associated with the suitcase portion, a second end of each leg being associated with a respective wheel of a second set of wheels; and a seat comprising a seat portion and a backrest configured to be stowed together and deployed from generally between the legs of the stroller frame, wherein the backrest pivots and rotates relative to the laterally opposed legs, a pivot, located at a top of the suitcase portion, where the stroller frame pivots and rotates relative to the suitcase portion; wherein the apparatus is movable between: a retracted suitcase configuration in which: the stroller frame is generally adjacent the rear of the suitcase portion such that the second set of wheels is generally adjacent the first set of wheels; and the seat is stowed between the legs of the stroller frame and against the rear of the suitcase portion such that the backrest and the front region of the suitcase portion generally define, respectively, a back and front of the suitcase configuration; and a deployed stroller configuration for seating and transporting a child in which: the stroller frame and seat are moved away from the rear of the suitcase portion such that the first set of wheels of the suitcase portion define rear wheels of the stroller configuration and the second set of wheels of the stroller frame are spaced from the first set of wheels to define front wheels of the stroller configuration; and the seat portion and backrest are deployed from the stroller frame to define the seat of the stroller configuration, and wherein the suitcase is rotated to a position nonorthogonal to the ground when in the deployed stroller configuration. ### Claim 2 (depends on 1) The convertible apparatus of claim 1, wherein the first end of each leg of the stroller frame is pivotably associated with the suitcase portion, the stroller frame being pivotal between: the retracted suitcase configuration, in which the stroller frame lies in a plane that is generally parallel to that of the rear of the suitcase portion; and the deployed stroller configuration, in which the stroller frame is pivoted away from the rear of the suitcase portion. ### Claim 3 (depends on 2) The convertible apparatus of claim 2, wherein the stroller frame is extendible and an upper end thereof is configured to define a handle for: transporting the convertible apparatus when in the retracted suitcase configuration; and wheeling the stroller when the convertible apparatus is in the deployed stroller configuration. ### Claim 4 (depends on 3) The convertible apparatus of claim 3, wherein the legs of the stroller frame are pivotal about an upper end of the suitcase portion, the legs being telescopically extendible to effect height adjustment of the handle. ### Claim 5 (depends on 4) The convertible apparatus of claim 4, wherein in the retracted suitcase configuration, the backrest and seat portion are folded together so as to lie on respective planes that are generally parallel to and/or the same as that of the stroller frame, and wherein in the deployed stroller configuration, the backrest and seat portion are unfolded from one another so as to define the seat. ### Claim 6 (depends on 5) The convertible apparatus of claim 5, wherein: in the retracted suitcase configuration, the second set of wheels assumes a stowed configuration; and in the deployed stroller configuration, the second set of wheels are deployed to engage the ground. ### Claim 7 (depends on 6) The convertible apparatus of claim 6, wherein in the retracted suitcase configuration, the second set of wheels is stowed at least partially beneath the suitcase portion. ### Claim 8 (depends on 7) The convertible apparatus of claim 7, wherein in the deployed stroller configuration: the suitcase portion is disposed toward a rear of the stroller and is angled forwardly in the direction of forward travel of the stroller configuration; and the backrest of the deployed seat is angled rearwardly such that a child seated thereon leans back and in the direction of rearward travel of the stroller. ### Claim 9 (depends on 1) The convertible apparatus of claim 1, further comprising a locking mechanism for selectively locking the stroller frame adjacent to and away from the rear of the suitcase portion in the retracted and deployed configurations respectively. ### Claim 10 A method of converting a convertible suitcase stroller apparatus from a suitcase configuration to a stroller configuration, comprising: moving a frame, the frame comprising a pair of laterally opposed legs, a first end of each leg being movably associated with a suitcase portion, a second end of each leg being associated with a respective wheel of a second set of wheels, and a seat away from a rear of a suitcase portion such that the second set of wheels is spaced apart from a first set of wheels in the direction of travel of the stroller such that the frame pivots at a pivot, located at a top of the suitcase portion, and rotates relative to the suitcase portion; and wherein the suitcase is rotated to a position nonorthogonal to the ground when in a deployed stroller configuration; deploying a seat portion and backrest from between the frame so as to define the seat of the stroller wherein the deploying includes pivoting and rotating the backrest relative to the laterally opposed legs. ### Claim 11 (depends on 10) The method of claim 10, wherein moving the frame comprises first releasing a locking mechanism to enable pivoting of the frame forward from the rear of the suitcase portion. ### Claim 12 (depends on 11) The method of claim 11, further comprising extending the frame upwardly such that an upper end of the frame defines a handle via which the stroller can be wheeled.
