A collapsible seat assembly is mounted on a frame of a stroller, and includes a joint member, a backrest support member, a leg support member and a locking mechanism. Each of a pivot portion of the backrest support member and a pivot portion of the leg support member is pivotably mounted on the joint member. The locking mechanism is disposed between the pivot portions to lock or unlock the backrest and leg support members. The locking mechanism is configured to be actuated to move from a locking position to an unlocking position by the operation of the frame of the stroller from an unfolded state to a folded state. A stroller having the collapsible seat assembly is also disclosed.

A child stroller apparatus includes a first side segment connected fixedly with a first shell portion and a grip portion that are disposed adjacent to each other, a second side segment fixedly connected with a second shell portion that is pivotally connected with the first shell portion, a latch assembled in a cavity delimited at least partially by the first and second shell portions, the latch being movable between a locking position that prevents relative rotation between the first and second side segments and thereby locks the child stroller apparatus in an unfolded state for use, and an unlocking position for folding and unfolding of the child stroller apparatus, and a release actuator assembled adjacent to the grip portion and operatively coupled to the latch, the release actuator being operable to cause the latch to move from the locking position to the unlocking position.

A child stroller apparatus includes a rear and a front leg frame respectively having a first and a second side segment, and a handle frame having a grip portion and a third side segment that are respectively connected fixedly with a first and a second joining part pivotally connected with each other, the second and third side segments being respectively connected pivotally with the first side segment. A latch is disposed between the first and second joining parts, and can lock the grip portion in an unfolded position relative to the third side segment. A cable has two opposite ends respectively anchored with the grip portion and the third side segment, wraps around a prominent portion provided on one of the first and second joining parts, and is tensioned to bias the grip portion to fold toward the third side segment.

A child stroller apparatus includes a standing frame, a push handle frame having a side segment that is 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 present invention discloses a baby stroller includes a stroller frame, a child carrier which is able to be positioned on the frame, and a locking component is able to lock the frame in an unfolding state. Said child carrier can be rotated relative to the stroller frame and allow a folding action of the frame during a pivotal movement of the child carrier relative to the stroller frame. Therefore, present invention allows a user to fold the child carrier and the stroller frame together, which brings convenience in use.

A child stroller apparatus includes a stroller frame, and an adapter assembled with the stroller frame and having a first coupling portion and a second coupling portion, each of the first and second coupling portions being configurable as a mount for installation of a detachable part. The adapter is movable relative to the stroller frame to displace the first and second coupling portions, a first position of the adapter configuring the first coupling portion as the mount while maintaining an angle between the first coupling portion and the second coupling portion, and a second position of the adapter configuring the second coupling portion as the mount while maintaining the angle between the first coupling portion and the second coupling portion.

A collapsible chassis for strollers includes a base frame supporting at least one front post and at least one rear post with wheel assemblies. The base frame further supports at least one handle tube. An actuation element is supported by the base frame and is actuated by the user to move the chassis from the open condition to the closed condition. The actuation element is movable with respect to both the handle tube and the movable post and is connected by way of a first kinematic connection element to the movable post and by way of a second kinematic connection element to the handle tube. Actuating the actuation element causes the rotation of the movable post and handle tube. A third kinematic connection element is provided which includes an articulation element adapted to cause a motion of mutual approach in a transverse direction of the two rear posts.

A stroller assembly may include a stroller frame, a plurality of wheels, and a support. The stroller frame may include a front horizontal bar and a rear horizontal bar. The stroller frame may be configured to operate between an open position and a collapsed position. The plurality of wheels may be connected to the stroller frame. The plurality of wheels may include one or more front wheels and one or more rear wheels. The support may be connected to the stroller frame. The support may include a first arm, a second arm, and a support wheel. The support and the one or more rear wheels may be configured to support the stroller assembly in a substantially vertical position when the stroller frame is in the collapsed position.

A stroller includes a frame, a first locking mechanism, a folding mechanism and a second locking mechanism. The frame is configured to be folded and unfolded between a folded state and an unfolded state. The first locking mechanism is disposed on the frame and for locking the unfolded frame and restraining the frame from being folded when the frame is in the unfolded state. The folding mechanism is movably disposed on the frame and connected to the first locking mechanism for driving the first locking mechanism to allow the frame to be folded. The second locking mechanism is disposed on the folding mechanism and separably abuts against the frame for restraining the folding mechanism from driving the first locking mechanism so as to lock the unfolded frame.

A child stroller apparatus includes a rear leg frame having a first side segment fixedly connected with a first coupling part, a front leg frame having a second side segment fixedly connected with a second coupling part, a handle frame having a third side segment fixedly connected with a third coupling part, the second and third coupling parts being respectively connected pivotally with the first coupling part, a front guard pivotally connected with the first coupling part, a first linking assembly rotationally coupling the second side segment with the third side segment, and a second linking assembly rotationally coupling the front guard with the second side segment. The front leg frame, the handle frame and the front guard are linked and rotatable relative to the rear leg frame during folding and unfolding of the child stroller apparatus.
