A stroller seat is mounted on a stroller and is provided with: a main part extending from a backrest to a seating part of the stroller and having a space therein through which air flows; an extension part protruding from at least one of the two side portions of the main body and having a space therein which communicates with the space of the main body; and a fan attachment part which is provided on the extension part and to which an electric fan can be attached. The main body has, on a surface to be in contact with a human body, an air discharge unit for discharging air therein to the outside. Air introduced by the electric fan attached to the fan attachment part flows into the main body through the extension part.

A seat height adjustment mechanism includes a locking bar and a locking element. The locking bar is disposed in a stroller frame and has locking holes spaced apart. Each of the locking holes has a stop portion protruding therein. The locking element is mounted on a seat and has an engaging end. The engaging end is separably engaged in any one of the locking holes and has an engaging hook protruding in a direction, and the direction is crossed with another direction in which the engaging end moves when the engaging end is separating from the locking hole. The engaging hook separably presses against the stop portion. Therefore, the engaging end cannot separate from the locking hole. Even when wrongly operated, the locking element cannot be rotated and unlocked and thereby prevents the seat from unnecessarily sliding downward, so as to ensure safety of a baby at the seat.

A seat includes a support base, an unlock member and a lock member. The support base has at least one through hole. The unlock member is movably disposed on the support base and has at least one first driving portion. The lock member is movably disposed on the unlock member. The lock member has at least one lock portion protruding from a surface of the support base through the at least one through hole and at least one second driving portion abutting against the at least one first driving portion. When the unlock member is forced in a first direction to move, the at least one lock portion is forced to move along the at least one first driving portion through the at least one second driving portion and retracts into the support base in a second direction different from the first direction.

A stroller includes a frame, a handle, a plurality of support legs, a wheel attached to a lower end of each support leg, and a seat attached to the frame. The seat includes an internal Peltier device for selectively heating or cooling the seat. The Peltier device is powered via an onboard battery installed in an electronics housing that includes multiple USB ports. A blanket is removably secured to the seat via one or more fasteners. A processor in the electronics housing performs a method that includes activating the Peltier device to bring the seat to a preset temperature, receiving a temperature setting for the Peltier device from a temperature control button disposed on the handle, detecting a current temperature of an area within the seat, and if the current temperature of the area within the seat is greater than a threshold safe upper temperature, then deactivating the Peltier device.

A stroller has a frame with at least two wheels and a seat unit for supporting a person sitting on it. The seat unit has a seat surface which is designed to be driven movable and/or wherein the seat surface has a plurality of driven movable partial surfaces. A movement pattern of the seat surface and/or the partial surfaces is predetermined in such a way that the back movement of a riding animal is simulated in at least one gait. The seat unit has a kinematic unit for predetermining the movement of the seat surface or the partial surfaces, which is arranged directly below the seat surface or directly below the partial surfaces. Alternatively or additionally, the stroller has a differential connected to at least two wheels so that a combined kinetic energy of these wheels is provided for the movement of the seat surface or the partial surfaces.

A baby wagon with improved ease of use has a folding structure which is stably configured, and thus damages to frames, such as twisting or bending of the frames, can be prevented, such that the baby wagon is stably folded and unfolded, the use of the baby wagon is convenient while durability of the baby wagon is excellent, and comfort of a baby can be maintained even when the baby is in the baby wagon for a long time. The frames are manufactured so as to be easily folded even in the state in which the canopy is coupled thereto, whereby the baby wagon is unfolded and folded within a short time, such that that portability and mobility of the baby wagon are excellent, and such that detachment and coupling of a canopy and a wheel assembly are easily performed.

A foldable backrest structure (50) adapted for a frame (40) of a child carrier (100), includes a backrest (30), a releasing mechanism (20) and a trigger (10). The backrest (30) is pivoted to the frame (40). The releasing mechanism (20) is disposed between the backrest (30) and the frame (40). The releasing mechanism (20) includes a first abutting component (22). The trigger (10) is disposed on the frame (40) and for slidably abutting against the first abutting component (22) to drive the releasing mechanism (20) to release the backrest (30), so as to allow the backrest (30) to be folded together with the frame (40) when the frame (40) is being folded. The foldable backrest structure (50) of the present invention has advantages of simple structure, easy operation and low manufacturing cost. Besides, the present invention further discloses a child carrier (100) including the aforementioned foldable backrest structure (50).

The present disclosure relates to a seat cover assembly of a baby stroller including a seat cover, a support structure and a pivot portion. The support structure is disposed in the seat cover and includes a first plate member and a second plate member that are movably connected. A seam is formed between the first plate member and the second plate member, and a width of the seam is less than a sum of a thickness of the first plate member and a thickness of the second plate member. The pivot portion is opposite the seam and close to a surface of the first plate member and a surface of the second plate member.

Embodiments include strollers having removable seats. An example stroller may include rear wheels, front wheels, and a frame including a handle portion, a rear wheel support portion, a front wheel support portion and a folding mechanism connecting the front wheel support portion and the handle portion in both an unfolded configuration and in a folded configuration. The frame may include a stroller seat support portion positioned at a first vertical position adjacent the handle portion, and a front seat attachment configured for attachment to the front wheel support portion at a second vertical position substantially lower than the first vertical position. The front seat attachment may be configured to support the front stroller seat substantially over the front wheels so that a center of gravity of the stroller system is between the front wheels and the rear wheels.

A pram may be used to transport babies and relatively young infants, and may provide a relatively horizontal surface for the baby or infant to be transported upon in a flat lying position. A pram may also be used to transport relatively older infants, and may provide a seat arrangement for the infant to be transported in a sitting position. However, babies and infants grow quickly and may outgrow conventional prams within a year or two years. Therefore, a parent or guardian must typically provide several prams for their child. Furthermore, a pram offering optimal comfort or safety may not be convenient when travelling or for city living. An aspect of the present disclosure includes a child transportation system comprising a frame 100, wherein the frame 100 is width adjustable between a relatively narrow compact arrangement and a relatively wide comfort arrangement. The frame 100 also includes an infant carrier attachment mechanism 500 configured and arranged to permit, in use, a seat 200 or an infant carrier module 300 to be releasably attached to the frame 100.
