A convertible inflatable device includes a first inflatable bed, a second inflatable bed, a front chamber, a left chamber, a right chamber, and a rear chamber. The first inflatable bed is surrounded by the front chamber, the left chamber, the right chamber, and the rear chamber. The front chamber, the left chamber, the rear chamber, and the right chamber are connected to each other sequentially. A first end of the second inflatable bed is connected to the junction of the first inflatable bed and the rear chamber. The convertible inflatable device can be converted to an inflatable bed, an inflatable boat, an inflatable water slide or an inflatable recliner chair, and the conversion between any of them is mutual and convenient.

An inflatable device which can fit with a portable SPA pool and has the advantages of low costs, a light weight and convenience for carrying and storage, and can serve as a step for a user to conveniently enter and exit the inflatable pool, a desk on the side of the SPA pool for placing personal articles and a stool for a user to rest near the portable SPA pool. An inflatable device for a portable SPA pool, comprising: a top sheet and a bottom sheet spaced apart from each other in a vertical direction; side walls extending between said top sheet and said bottom sheet, upper edges of said side walls being connected to outer edges of said top sheet, respectively, and lower edges of said side walls being connected to outer edges of said bottom sheet, respectively so as to form an inflatable air chamber; and at least one group of tensioning structures, said tensioning structure being disposed in said air chamber and connected to said top sheet, said bottom sheet and said side walls respectively so as to limit the outward bulging of said top sheet, said bottom sheet and said side walls when said air chamber is inflated.

A pneumatic adjustment arrangement for a vehicle seat. The pneumatic adjustment arrangement has at least one chamber or bladder, which can be filled with a pressure medium, as an adjustment element. Furthermore, the pneumatic adjustment arrangement has a fluid line for the filling and/or evacuation of the chamber. Additionally, the pneumatic adjustment arrangement has a valve device which is provided in the fluid line for volume flow regulation. Finally, the pneumatic adjustment arrangement has a noise absorber which is likewise arranged in the fluid line in order to absorb noise generated in the fluid line. In this way, it is possible to create a pneumatic adjustment arrangement for a vehicle seat, in particular for comfort functions, such that objectionable noises during the execution of the comfort fiction are reduced.

A support system includes two cushions. The first cushion is divided into a plurality of bladders filled with a fluid, the bladders being connected by fluid interconnections. The second cushion is coupled to the first cushion. The second cushion is also divided into a plurality of bladders filled with a fluid, the bladders connected by fluid interconnections. When a force is applied to one of the plurality of bladders, a reactionary force is produced in a different one of the plurality of bladders in the same respective cushion.

Provided are an inflatable product and an inflatable product fusing process. The inflatable product comprises an upper sheet, a lower sheet, pull straps provided therebetween, and upper and lower fixing sheets having one faces away from each other respectively joined with inner surfaces of the upper and lower sheets and one faces facing towards each other not joined. The pull strap has oppositely-provided upper and lower pull strap sheets of porous material. The upper sheet, upper pull strap sheet, upper fixing sheet, lower fixing sheet, lower pull strap sheet and lower sheet are successively provided. When processing using a hot-fusing machine or high-frequency machine, the upper and lower pull strap sheets are simultaneously jointed with the upper and lower fixing sheets, therefore the inflatable product can be one-step formed and no separating sheet needs to be provided in the pull strap, thus simplifying manufacturing process and improving production efficiency.

A methane conversion device comprises a reaction chamber; a sensor for detecting the presence of methane; blowing means for directing external gasses Into the reaction chamber when the sensor detects the presence of methane above a predetermined threshold; conversion means that are configured to oxidise methane; and positioning means for positioning the device on an animal.

A chair facilitates both rocking and bouncing. The chair includes a base adapted to support a seating portion, the seating portion having a surface adapted to be sat on by a user. The seating portion has a bouncing mechanism, such as an exercise ball. A rocking mechanism is provided to cause the base to rock. The rocking mechanism facilitates the rocking back and forth of the user when the user is seated on the seating portion, and the bouncing mechanism facilitates the bouncing of the user when the user is seated on the seating portion. The bouncing is in a bouncing direction that is different than the direction of rocking. The chair is particularly useful for calming a baby and/or for facilitating stimming.

An adjustable chair frame with a back and seating surfaces that flex to conform to the shape, weight and movement of an occupant is disclosed. The chair form and proportions provide for a recumbent position that disperses the weight of the occupant more evenly, thereby reducing external and internal physiological point loading. The form also provides ergonomic articulation to minimize internal physiological stresses such as neck/back vertebral compression. Eccentric connections driven by a motor assembly allow positioning adjustment of the components of the chair. Additionally, an air pump assembly may be included to automatically adjust one or more air bladders provided on the interior of the chair frame.
