An associated method for folding the stroller is also disclosed, the method for collapsing the stroller including the steps of moving the second seat from its in use position to its stowed position, and then folding the stroller.The method for erecting the stroller being the reverse of the method for collapsing this. ## Claims ### Claim 1 A stroller comprising a first passenger support and a second seat positioned behind the first passenger support, the second seat having an in use position and a stowed position, where the second seat can be moved between the in use and stowed positions and back again without need to reposition the first passenger support or be separated from the stroller. ### Claim 2 (depends on 1) The stroller of claim 1, wherein the stroller is adapted to be folded between an in use configuration and a collapsed configuration in two stages, the first stage comprising a movement of the second seat from its in use position to its stowed position, and the second stage being a folding of the stroller. ### Claim 3 (depends on 1) The stroller as in claim 1, wherein the second seat is adapted to move to and from its stowed position with a combined sliding and rotating action. ### Claim 4 (depends on 1) The stroller as in claim 1, wherein as the second seat moves to its stowed position, it slides toward the first passenger support and reclines away from the same. ### Claim 5 (depends on 1) The stroller as in claim 1, wherein as the second seat moves to its in use position, it slides away from the first passenger support and inclines toward the same. ### Claim 6 (depends on 1) The stroller as in claim 1, the stroller further comprising a first frame assembly supporting the first passenger support, and a second frame assembly supporting the second seat, the second frame assembly being pivotally connected to the first frame assembly. ### Claim 7 (depends on 6) The stroller of claim 6, wherein the first frame assembly is comprised of an upper sub frame and a lower sub frame, where these are pivotally connected to one another via a releasably lockable hinge mechanism, for folding between the stroller's in use configuration and the collapsed configuration and back again. ### Claim 8 (depends on 7) The stroller of claim 7, wherein the lower sub frame is supported on one or more castor wheel assemblies. ### Claim 9 (depends on 7) The stroller of claim 7, wherein the upper sub frame of the first frame assembly supports the first passenger support and provides a handle via which the stroller can be pushed. ### Claim 10 (depends on 6) The stroller as in claim 6, wherein the second frame assembly comprises a pair of arms, where each of these arms is pivotally connected to the lower sub frame of the first frame assembly at or toward a first end thereof, and where each of these arms carries\a wheel assembly at or toward a second end thereof. ### Claim 11 (depends on 10) The stroller of claim 10, wherein the second seat is supported on a carriage frame which is in turn supported between the arms of the second frame assembly. ### Claim 12 (depends on 11) The stroller of claim 11, wherein, the second seat is adapted to slide along and pivot relative to this carriage frame so that it may move between its in use and stowed positions. ### Claim 13 (depends on 10) The stroller as in claim 10, wherein the carriage frame comprises user operable locking means which permit the second seat to be locked in at least the in use and stowed positions. ### Claim 14 (depends on 1) The stroller as in claim 1, wherein the first passenger support is a seat. ### Claim 15 The stroller of clam 14, wherein in the in use position, the second seat is both behind and lower than the first seat. ### Claim 16 (depends on 1) The stroller as in claim 1, wherein the first passenger support is a bassinet. ### Claim 17 A method of folding a stroller from its in use configuration to its collapsed configuration, the stroller comprising a first passenger support and a second seat positioned behind the first passenger support, the second seat having an in use position and a stowed position, where the second seat can be moved between the in use and stowed positions and back again without need to reposition the first passenger support or be separated from the stroller, the method comprising moving the second seat from its in use position to its stowed position, and then folding the stroller. ### Claim 18 (depends on 17) The method of claim 17, further comprising releasing the carriage frame locking mechanism and sliding the second seat along the carriage toward the first end of the arms, this simultaneously causing the second seat to recline to a stowed position close to the arms, and then releasing the lockable hinge mechanism of the first frame assembly so that the lower sub frame can be folded beneath both the upper sub frame and the second frame assembly. ### Claim 19 A method of folding a stroller from its collapsed configuration to its in use configuration, the stroller comprising a first passenger support and a second seat positioned behind the first passenger support, the second seat having an in use position and a stowed position, where the second seat can be moved between the in use and stowed positions and back again without need to reposition the first passenger support or be separated from the stroller, the method comprising unfolding the stroller, and then moving the second seat from its stowed position to its in use position. ### Claim 20 (depends on 19) The method of claim 19, further comprising unfolding the lower sub frame from beneath the upper sub frame and the second frame assembly until the lockable hinge mechanism locks the lower sub frame with respect to the upper sub frame, and then releasing the carriage frame locking mechanism and sliding the second seat along the carriage toward the second end of the arms, this simultaneously causing the second seat to incline into its in use position.
