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 child stroller includes a stroller frame and a first seat. The stroller frame has two sections capable of being folded and unfolded relative to each other. The first seat is disposed on one of the two sections in a detachable manner. The first seat includes a supporting unit and a first seat frame. The first seat frame is adapted to hold the supporting unit. The first seat frame includes a seat hub, an upper seat tube and a lower seat tube. The seat hub is disposed on the stroller frame. The upper seat tube is disposed on the seat hub, and the supporting unit is slidably disposed on the upper seat tube. The lower seat tube is disposed on the seat hub and detachably connected to the supporting unit.

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.

A stroller is disclosed. The stroller includes a support frame supported by at least two wheels. The stroller also includes a seat carrier support selectively, removably coupled to the support frame. A swing motor is operatively coupled to the seat carrier support. A seat swing mechanism extends downwardly from the swing motor. The seat swing mechanism has a seat yoke configured to receive and retain an infant seat. The seat swing mechanism is configured to swing the infant seat forwards and backwards when the swing motor is activated.

Foldable strollers and related methods are disclosed herein. An example frame for use with a stroller includes a first leg having a first wheel coupled thereto, a second leg having a second wheel coupled thereto, a first joint to couple the first leg and the second leg, a handle arm, and a second joint to couple the handle arm and the first leg. The handle arm is to rotate relative to the first leg via the second joint. The rotation of the handle via the second joint is to cause the second leg to rotate relative to the first leg via the first joint to fold the frame.

A child stroller apparatus includes a stroller frame, and a stroller seat supportable by the stroller frame. The stroller seat includes a backrest portion fixedly connected with a first joining part, a seat portion fixedly connected with a second joining part that is pivotally connected with the first joining part, a coupling part pivotally connected with the second joining part and adapted to connect with the stroller frame, a latch movable between a locking position engaged with the coupling part and an unlocking position disengaged from the coupling part, and a linking mechanism configured to movably couple the latch to the first joining part so that a rotation of the backrest portion in a folding direction causes the latch to disengage from the coupling part, and a rotation of the backrest portion in an unfolding direction causes the latch to engage with the coupling part.

A movable carrier includes a bottom frame assembly, a first support member, a link assembly, a position mechanism, and a first unlock member. The first support member has a first end portion pivotally connected to the bottom frame assembly. The link assembly includes a link member and a first connect member. The link member is disposed at a second end portion of the first support member. The first connect member is pivotally connected to the link member and connected to the second end portion through the link member. The position mechanism is disposed on the link assembly and corresponds to the first connect member. The first unlock member is disposed on the link assembly and connected to the position mechanism. When the first unlock member contacts the bottom frame assembly, it carries the position mechanism to move to change the position of the first connect member.

A child seat includes a seat portion fixedly connected with a first coupling part, a connector pivotally connected with the first coupling part of the seat portion, the connector being operable to detachably engage with a corresponding structure provided on a child supporting apparatus, a locking mechanism operable to lock and unlock the connector with respect to the seat portion, a backrest frame fixedly connected with a second coupling part that is pivotally connected with the first coupling part, and a coupling mechanism operable to movably couple the seat portion to the backrest frame so that the seat portion and the backrest frame are movable in unison relative to the connector during adjustment of the backrest frame between an unfolded state and a folded state.

A child stroller apparatus includes a standing frame, a push handle frame having a side segment, the side segment being pivotally connected with the standing frame via a pivot connection, an adapter having a coupling portion configured to receive the installation of a detachable part, the adapter being fixedly connected with a handle, the handle having a cavity through which is slidably disposed the side segment so that the handle and the adapter are slidable in unison along the side segment for adjustment, and a locking mechanism for locking the adapter in position on the side segment, the locking mechanism including a release actuator exposed on the handle for operation, the release actuator being operable to cause the locking mechanism to unlock for sliding adjustment of the handle and the adapter along the side segment.

Foldable strollers with removable seats and related methods are disclosed herein. An example stroller disclosed herein a wheeled frame, a receiver coupled to the frame, and a seat. The seat includes a mount, a lock disposed in the mount; and a handle having an extended positon and a retracted position relative to the seat. The lock is to move from a first position to a second position when the mount is disposed in the receiver to removably couple the seat to the frame, and the lock to move from the second position to the first position to release the seat from the receiver when the handle moves from the retracted position to the extended position.
