A multi child stroller includes a stroller frame and a first seat. The stroller frame has two sections adapted to fold and unfold relative to each other. The first seat is disposed on one of the two sections. The first seat includes a first seat unit and a seat back positioning member. The first seat unit has a sliding slot portion. The seat back positioning member is rotatably disposed on the stroller frame. The seat back positioning member includes a sliding bar adapted to slide inside the sliding slot portion, so as to switch the first seat unit into one of a first unfolding mode, a second unfolding mode and a folding mode.

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.

A rod locking mechanism includes a central hub, a first rod component and a locking component. The first rod component is pivotally connected to the central hub. The first rod component includes an abutting portion. The abutting portion is movable between a first position and a second position when the first rod component pivots relative to the central hub. The locking component is movably disposed on the central hub. The abutting portion is located at a first side of the locking component when the abutting portion is located at the first position. The abutting portion drives the locking component to move when the abutting portion moves from the first position toward the second position, and the abutting portion abuts against a second side of the locking component opposite to the first side of the locking component when the abutting portion is located at the second position.

A carrier adjusting mechanism is applied to a stroller including a stroller frame and a carrier and includes a base, a locking structure, a locking device, and a release actuator. The base is connected to the stroller frame. The locking structure is connected to the carrier and pivoted to the base. The locking device is disposed between the base and the locking structure. The locking device includes a first engaging structure, a second engaging structure, and a locking member. The locking member is engaged with the first engaging structure at a first position or the second engaging structure at the second position. The release actuator is disposed on the stroller and connected to the locking device for disengaging the locking member from the first engaging structure or the second engaging structure, to allow the locking structure to move between the first position and the second position together with the carrier.

An accommodation device includes a seat assembly, at least one flexible adjustment strap and an accommodating cavity having a bearing portion and a flexible circumferential surrounding portion. The accommodating cavity is rotatable between a lying state and a sitting state. When in the sitting state, a side of the circumferential surrounding portion reaching a topmost point is a first side portion, and a side opposite to the first side portion is a second side portion. The bearing portion has at least two foldable portions forming a first portion close to the first side portion and a second portion far from the first side portion. The adjusting strap is tensioned by the seat assembly and the first side portion when in the sitting state. The second portion is moved to form a seat portion during rotation to the sitting state, and the first portion is supported by the adjusting strap to form a backrest portion.
