A back-following support device, a control method for preventing sedentariness, and a chair are provided. The back-following support device including: a backrest plate; a flexible back and waist support, including a cushion airbag disposed over the backrest plate; and a control system, including a controller, an air supply device for inflating the cushion airbag, a pressure-regulating valve for controlling the amount of air in the cushion airbag, and an air pressure sensor for detecting air pressure inside the cushion airbag; the air supply device, the pressure-regulating valve, and the air pressure sensor are all connected to the controller. The seat and the back-following support device can be adjusted to make the chair more comfortable, thereby effectively supporting the user's waist and/or back and meeting requirements of different people.

Systems herein provide a customizable camp chair cover that may provide additional functional features and/or aesthetic elements to portable seating. In some examples, portions of the camp chair cover are inflatable and/or receive inserted inflation devices for customized support at various areas of seating when attached to the chair. Portions of the camp chair cover may be configured to provide access to portions of the chair and/or accessories. The camp chair cover may also be customized to provide team logos, designs, colors, and other aesthetic elements.

Systems and methods herein provide a customizable camp chair that may provide added levels of comfort to portable seating. In some examples, portions of the camp chair are inflatable to provide customized support at various areas of the chair. In other examples, portions of the camp chair are configured to receive inserted inflation devices for customized support at various areas of the chair. The chair may include an integrated air pump, which aids in inflation.

An anti-pinch system for an electric seat includes a plurality of infrared sensing modules, a seat cushion hose, a footrest hose, a pressure sensor, at least one linear actuator, a central processing unit, a power module and a control module. When the user operates the electric seat to act, the plurality of infrared sensing modules and the pressures sensor synchronously sense whether an obstacle is under the electric seat. If an obstacle exists under the electric seat, the central processing unit will control the at least one actuator to stop or to reversely act. When the user cannot perceive obstacles by themselves, the electric seat can be automatically prevented from pinching obstacles, thus avoiding damaging the obstacles or the electric seat.

An office, work and leisure chair and retrofit kit for subliminal motions of the seated person. The chair has a cruciform base (1) with rollers (4), a pneumatic spring-action post (2) with an interface plate (5) for a seat panel (21) and seat pad (19), and a backrest (22). The seat panel is mounted with wobble capability on a pneumatic cushion, which has deformable air chambers (18, 35) connected by connecting hoses (27) and lies on an elastically deformable hollow body (14). The hollow body pumps the air chambers when a person sits down and stands up. A pump hose (12) with a one-way valve leads from the hollow body to compensate for leakage losses. Connecting hoses between the air chambers have valves (31; 75; 89) such that the wobbling distance of the seat panel and the damping of the wobbling motion is variable.

Office, work and leisure chair and retrofit kit for causing subliminal movements of the person sitting thereon. The chair has a cruciform base (1), freely articulated rollers (4), a gas-spring support (2) and an interface panel (5) resting thereon as a support panel. Mounted on the support panel is a base panel (28) bearing a seat cover (19) with a seat surface and back rest (22). The seat cover is provided and allowed to wobble, resting via a cover panel (27) on a plurality of spring elements (7), which are displaceable radially, or obliquely in relation to the radial direction, or helically from the center of the base panel to the periphery of the base panel. The spring elements are mechanically, hydraulically, pneumatically or electrically displaceable, so that the wobble distance of the seat cover and the attenuation of the wobble movement are variable.

An air cushion type independent pocket spring structure, mainly being an independent pocket spring having a top cushion and a lower cushion; the top cushion and the lower cushion are respectively located in a top portion and a bottom portion of the independent pocket spring, and a plurality of the independent pocket springs are on a base. The independent pocket spring is compressible and resilient; wherein the independent pocket spring has an air inlet valve and an air outlet valve provided thereon; an air outlet tube is connected to the air outlet valve of the independent pocket spring and the air inlet valve of an adjacent independent pocket spring, and an air inlet tube is connected to the air inlet valve of the independent pocket spring and the air outlet valve of an adjacent independent pocket spring.

A methane conversion device is provided that includes a reaction chamber comprising a converter that is configured to oxidize methane. A sensor is provided that is adapted to detect the presence of methane within gas exterior to the methane conversion device. A positioner is provided for positioning the device on an animal.

Padding (10) for support devices suitable for providing support to a person in a sitting or lying position, comprising a body (12) made of non-deformable and compressible material, having a plurality of seatings (18) and filling elements (20, 26) removably arranged in the seatings (18) and having the function of correcting the posture of a user.

The invention relates generally to a system and methods for facilitating correcting and maintaining a good posture. More specifically, the invention is directed to a posture correcting chair including a seating component, a pump mechanism, and a frame assembly. The seating component may include an inflatable element and a base element. The inflatable element and the base element form a housing. The pump mechanism may include a pumpsuch as a mechanical or electrical pumpfor pumping a medium into or out from the housing such that an occupant of the seating component may maintain a good posture.
