Abstract: A folding stroller having a frame that can be arranged in at least a first configuration and a second configuration, the frame including a handgrip fixedly connected to an upper joint, a lower joint pivotally connected to the upper joint, the lower joint being fixedly connected to a front tube, a rear joint pivotally connected to the lower joint, the rear joint being fixedly connected to a rear tube, and a joint connecting rod connected to the lower joint, the rear joint, and the upper joint, wherein a distance between the upper joint and the rear joint is larger than a predefined threshold while the frame is in the first configuration, while the frame is in the second configuration, and while the frame is transitioning between the first configuration and the second configuration.

Abstract: A stroller with a pivotable front wheel assembly. When folding the stroller, the front wheel assembly may pivot, exposing a flat surface which may be rested on the ground for easier storage of the stroller. A drive rod may drive the front wheel assembly to rotate during folding. A slider may move away from the front wheel assembly during folding, moving a rear tube into place and ultimately causing the drive rod to drive the front wheel assembly to rotate. A lock mechanism may be included to lock the frame into configuration.

Abstract: A collapsible stroller comprising a frame and a reversible seat (5) comprising an armrest portion (5.5) is provided. The reversible seat (5) is mountable via an attachment point on the stroller frame in either a forward or rearward orientation with respect to the stroller frame, and in such a way that the attachment point can be moved relative to the stroller frame for collapse of the reversible seat (5) along with the stroller frame, irrespective of the reversible seat's orientation. An associated reversible seat structure is also disclosed.
