Abstract: Disclosed is a stroller chassis with a hub. The stroller chassis comprises a first frame assembly and a second frame assembly. The hub is configured to couple the first frame assembly to the second frame assembly pivotably about a pivot axis and releasably lockably with respect to each other. The hub is configured to detachably and lockably support a carrying structure on the chassis. The hub is configured to support the carrying structure relative to the chassis pivotably about the pivot axis and lockably in a rotational position. Also disclosed is a stroller chassis with a hub. The hub is configured to detachably and lockably support a carrying structure on the chassis. The hub is configured such that fully unlocking the carrying structure from said hub to allow detachment may be caused by operation of only one release member.

Abstract: A stroller and foldable frame assembly for a stroller includes a locking mechanism adjustable between a locked position and an unlocked position. The locking mechanism is configured to releasably lock the foldable frame assembly in its use configuration and/or storage configuration by releasably and internally locking at least one of a respective swivel joint assembly of the frame assembly. The locking mechanism includes an actuation element configured to adjust the locking mechanism between the unlocked and the locked position that is arranged spaced apart transversely to a swivel axis of the respective at least one internally lockable swivel joint.
