ABSTRACT:
A collapsible stroller has a frame assembly with a front, a back, and left and right sides when in an in-use configuration. A seat is positioned between the left and right sides. Each of the left and right sides has an elongate bottom part and each bottom part has a front end and a back end. A back wheel is supported for rotation at the back end of each of the bottom parts. Each of the left and right sides has a front leg with a lower end pivotally connected to the front end of the respective bottom part. Each front leg extends upward from the bottom part and rearward toward the back of the frame assembly and terminates at an upper end. Each of the left and right sides also has a push arm pivotally coupled relative to the upper end of the respective front leg. Each push arm extends upward and rearward from the upper end of the respective front leg. Each of the left and right sides further has a support strut with a lower end pivotally connected to the respective bottom part at a pivot location between the front and back end of the bottom part. Each support strut terminates at an upper end in proximity to the respective front leg or the respective push arm. Each bottom part has a portion rearward of the pivot location of the support strut. The elongate bottom parts between the pivot locations and the respective front ends are curved. When the frame assembly is in the in-use configuration, the bottom parts are each curved upward from the pivot location to the front end.
