US Patent 9481389 Convertible jogging and all-terrain strollers

A convertible stroller for selectively converting between two different active use modes is provided. The convertible stroller may include a frame supporting at least one front wheel, rear wheels, and a seat base for supporting (or including) a seating surface. The seat base is operable to be selectively positioned in at least two different use modes, a first use mode and a second use mode, wherein the first use mode positions the seat base at a relatively higher position than in the second use mode. In some examples, the frame and/or wheels are also operable to transition to a longer wheel base in the second use mode.
