FOLDING BEARING STRUCTURE, STROLLER

摘要

A bearing structure includes a wheel assembly defining a first front wheel assembly and a second rear wheel assembly, the rear wheel assembly including at least two wheels spaced by a first width defining a first position; wheel supports connecting the axes of rotation of the wheels with the bearing structure; a first folding device enabling a first folding causing a reduction in spacing between the two rear wheels to a second width lower than the first width, defining a second position. A connection system, connecting the wheel supports of the first and second assemblies to the first folding device, enables a second folding of the wheels so as to allow a rotation substantially equal to 90° of the wheels in the horizontal plane when the wheels are in the second position.
