A snapping structure is provided, which is configured to detachably mount a body to a support frame. The snapping structure includes a locking member movably disposed on the body and a positioning member disposed on the support frame and mated with the locking member. The locking member is movable to be locked to the positioning member, so as to mount the body to the support frame, or the locking member is movable to be unlocked from the positioning member, so as to separate the body from the support frame.

An armrest folding mechanism pivotally connected to an armrest and connected to a first connecting rod of a connecting seat for folding the armrest with the retraction of the second connecting rod relative to the first connecting rod, comprising: a locking member, including a locking end, a connecting end, and a first rack part located between them, the locking end is releasably fitted to the armrest, and a first toothed structure is arranged on the first rack part; a pushing member including a pushing end and a second rack part, a second toothed structure iptOs correspondingly arranged on the second rack part relative to the first toothed structure, the pushing end moves by the second connecting rod; an elastic element with a first end connected to connecting end and a second end abutting against the connecting seat; and a driving gear engaging with the first and second toothed structures.

A snapping structure is provided, which is configured to detachably mount a body to a support frame. The snapping structure includes a locking member movably disposed on the body and a positioning member disposed on the support frame and mated with the locking member. The locking member is movable to be locked to the positioning member, so as to mount the body to the support frame, or the locking member is movable to be unlocked from the positioning member, so as to separate the body from the support frame.

A stroller is provided with the ability to removably couple and decouple a seat from the stroller as needed. The stroller can include a stroller frame. The stroller can also include one or more front wheels attached to the stroller frame and one or more rear wheels attached to the stroller frame. The stroller can also include a first seat coupled to the stroller frame. The stroller can include first and second seat attachment housings. Each of the seat attachment housings can include a cavity for receiving a corresponding one of the first and second seat attachment adapters. Each of the seat attachment housings can also include a door cover to prevent access to the respective cavity when not in use. The seat attachment adapters can be coupled to the respective seat attachment housings and a second seat can be coupled to the seat attachment adapters.

A seat (1000) may include mounting components (1054a. 1054b) that may mate with corresponding components on other assemblies. The seat may include one or more features that may rotate or move to provide for coupling to the one or more assemblies. Assemblies include, but are not limited to, a stroller, a bicycle adapter, a wagon, a booster seat, a camping chair, a high chair, a stadium seat/picnic table, a hiking pack, an infant carrier, a car seat, a booster car seat, or an airline seat.

A child seat includes a front guard and a backrest frame respectively connected pivotally with the seat portion about a first and a second pivot axis, and a folding mechanism including a latch pivotally connected with the seat portion about a third pivot axis for locking and unlocking the front guard with respect to the seat portion, and a linking part coupled to the latch and pivotally connected with the backrest frame about a fourth pivot axis. A rotation of the backrest frame from a deployed position toward a collapsed position causes a displacement of the linking part that urges the latch to unlock the front guard. The first, third, second and fourth pivot axes are arranged in that order along a direction from a front to a rear of the seat portion when the backrest frame is in the collapsed position and the front guard in a folded position.

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 multi-stage toy walker includes at least a handle, a base, and a configurable component that is adjustable from a folded-flat configuration to at least one of a seat-shaped configuration and a basket-shaped configuration.

Integrated environmental infant pram, pet mat, and an integrated environmental infant footmuff are disclosed. System apparatus provides programmable heating/cooling functions, real-time monitoring of the temperature of the pram, mat or footmuff, programmable alarm settings, Bluetooth proximity location, wireless and/or Bluetooth connectivity to separate handheld digital devices, weight sensor inputs, a rechargeable battery power supply with recharging/power connectivity, and microprocessor control of heating/cooling, sensory input/output functions, and communication functions. Embodiments of the infant prams are disclosed as original manufactured equipment or an adaptable retrofit assembly. An artificial intelligence component of the programmable heating/cooling method is also disclosed.

A child carrying device comprising a frame mounted on a set of wheels or castors to enable the device to be manually conveyed thereon, and a seat mounted on said frame, said device including adjustment means for selectively reconfiguring the device such that it is operable as any one of a stroller, a child back carrier and a high chair.
