An optionally deployable side seat for a baby stroller, to seat a second child, is secured by hand-operated connectors to nearly any baby or child stroller, without tools. The side seat faces to the side of the stroller and has a deployed position in which two wheels mounted in tandem on the side seat frame contact the pavement. For stowing the side seat remains on the stroller, and two quick-release lockable joints, in the position of arms on the side seat, are released and raised upwardly, which folds the seat bottom up against the seat back and raises up a lower frame portion that supports the wheels.

1. An optionally deployable side seat for a baby stroller to seat a second child, comprising: a frame including a seat bottom frame and a seat back frame and supporting a seat and back having a direction of child orientation, and at least one wheel supported for rotation on a lower portion of the frame and positioned, when the side seat is deployed, to contact a surface on which a baby stroller rolls, the wheel having a rolling axis generally aligned with said direction of child orientation such that the wheel rolls and advances in a movement direction perpendicular to the direction of child orientation,the frame having a plurality of releasable connectors extending back from a rear side of the frame and capable of securing to frame members on one side of a baby stroller, such that said direction of child orientation of the side seat is toward the one side and perpendicular to said movement direction, andthe frame being capable of folding to a stowed configuration, having a first horizontal pivot axis at which the seat bottom frame is connected to the seat back frame such that the seat bottom frame folds up against the seat back frame for stowing, and said lower portion of the frame being pivotally connected, on a second horizontal pivot axis, to the seat bottom frame and extending downward from the seat bottom frame, with a means for retaining the lower portion of the frame in the deployed position. 2. The side seat of claim 1, wherein the frame includes three said releasable connectors. 3. The side seat of claim 1, wherein each releasable connector includes a base end secured to the frame of the side seat and a stroller attachment end configured to grip a frame member of a stroller, with a lever on the connector which when moved to a locking position will lock the connector onto a frame member of a stroller. 4. The side seat of claim 1, wherein each releasable connector has a base end secured to the frame of the side seat and a shaft leading to a stroller gripping end, the connector having provision for angular adjustment in orientation from the side seat frame and for rotational adjustment of the stroller gripping end relative to the base end. 5. The side seat of claim 1, wherein each releasable connector has a stroller gripping end that includes a tubing gripping head with a spring-biased gripper which is quickly releasable with a hand-operated lever. 6. The side seat of claim 5, wherein the gripping head includes three contacts of resilient material positioned to partially surround a tubing frame member of a stroller, the spring-biased gripper comprising a movable resilient contact pivotally mounted on the releasable connector to swing with spring bias toward the three contacts so as to enclose and grip a tubing frame member in the gripping head. 7. The side seat of claim 1, wherein two said wheels are included, both supported on the lower portion of the frame in tandem positions. 8. The side seat of claim 1, wherein the lower portion of the frame is generally U-shaped. 9. The side seat of claim 8, wherein two said wheels are included, both supported on the U-shaped lower portion of the frame in tandem positions. 10. The side seat of claim 1, wherein the lower portion of the frame extends upwardly beyond said second horizontal pivot axis to a pair of quick-release lockable joints at each of two ends of the lower frame portion, defining a third horizontal pivot axis at said lockable joints, and including two short linkage arms, one extending from each lockable joint upwardly and back, when the side seat is deployed, to a connection with the seat back frame defining a fourth horizontal pivot axis, such that for stowing the side seat, each of the lockable joints is released and swung upwardly with the short linkage arms, causing the seat bottom frame to pivot upwardly along the first horizontal pivot axis while raising the lower frame portion upwardly and swinging the wheel inwardly to stowed configuration, said quick-release lockable joints serving as said means for retaining the lower portion of the frame in the deployed position. 11. The side seat of claim 10, wherein the lower frame portion is generally U-shaped. 12. The side seat of claim 11, wherein the locking mechanism includes two locking positions, one at deployment of the side seat and one at stowing of the side seat. 13. The side seat of claim 10, wherein each lockable joint includes a spring-biased locking mechanism, with an external push button effective to release the locking mechanism. 14. The side seat of claim 1, wherein the seat back frame is generally inverted U-shaped, and wherein the seat and back supported by said seat bottom frame and back frame are flexible.
