Disclosed herein is a dynamic pendula stool possessing a foot, a leg secured to the foot, and a seat secured to the top end of the leg. The leg has a telescopic column that includes a lower part secured to a spherical foot with a diameter of 20-cm or less and an upper part with a free end having an articulation. The articulation has three degrees of freedom and is secured to the underside of the seat so that when a user rests against the seat, the leg forms an angle between 30 and 90 degrees with respect to the horizontal, thereby allowing an isometric contraction of the muscle groups of the lower limbs and of the abdominal girdle in the seated position. The stool is further provided with one or more sensors configured to send data signals to a remote electronic device.

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 pelvic tilt detecting chair is provided to a user to sit and configured to detect a pelvic angle of the pelvis of the user in sitting position. The pelvic tilt detecting chair comprises a base, a supporting component, a carrying component and a detector. The base has a horizontal surface. The supporting component comprises a first end connected to the base and a second end. The carrying component is moveably configured and comprises an installing surface coupled to the second end and a chair surface configured to contact the pelvis of the user. The chair surface and the horizontal surface form a tilt angle when the user sits on the carrying component. The detector stores a tilt angle threshold value and is configured to the carrying component to detect the tilt angle. The detector generates a warning signal when the tilt angle is not matched up with the tilt angle threshold value.

The invention relates to an active dynamic seating (1) comprising a foot part (2) and a pendulum joint (10) which is rotatably mounted relative to the foot part (2), a seat (3) which is rotatably mounted relative to the foot part (2), and a pendulum column (4) supporting the seat (3), said pendulum column (4) being connected for conjoint rotation with the pendulum joint (10). The pendulum column (4) is designed to be resilient in a height direction H and the pendulum column (4) is provided with anti-rotation means (51, 52, 53) which rotationally immobilize the pendulum column (4) relative to the seat (3) such that the pendulum column (4) and the seat (3) can be rotated relative to the foot part (2) only together with the rotatable pendulum joint (10).

A movable human support structure has a support against which at least a part of a human can be borne in use, a base, and a first motion transmitting assembly acting between the support and the base. The first motion transmitting assembly has at least one link member connecting between the base and the support. The at least one link member is configured to be movable: a) relative to the support around a first axis; and b) relative to the base around a second axis. The first and second axes are non-parallel to each other. The first motion transmitting assembly is configured to guide movement of the support relative to the base in opposite directions in a non-straight path.

The tipping chair (10) includes a main strut (12), a pivot seat (34) on the strut (12), a pivot slot (18) defined in the main strut (12) and a pivot strut (24) pivotally secured within the slot (18). Pivoting a prop end (28) of the pivot strut (24) out of the slot (18) of the main strut (12) backward toward a bottom end (14) of the main strut (12) causes a seat end (26) of the pivot strut (24) to raise the pivot seat (34), and the seat end (26) becomes secured to a latch (42) on an a brace surface (40) opposed to a seating surface (38) of the pivot seat (34) to position the chair (10) in a seated configuration. Reversing the process returns the chair (10) to a flat, stored configuration to be optionally stored as wall art.

A spine-protecting and spine-correcting multi-functional health-care seat device employing gravity to achieve embrace-like support, pressure reduction, fixing, and correction, including a seat frame and a gravity embrace-like support and sitting device. The gravity embrace-like support and sitting device includes a sitting plate (1), sitting plate support rods (8) symmetrically arranged on two sides of a bottom of the sitting plate (1), rotating bearings (1101) symmetrically arranged on two sides of the seat frame, embrace-like support levers cooperatively arranged on the rotating bearings (1101), and embrace-like support palms (2) arranged at top ends of the embrace-like support levers. One end of each sitting plate support rod (8) is hinged to a bottom of the sitting plate (1), and the other end is hinged to a bottom of each embrace-like support lever through a support rod rotating shaft (15).

An ergonomic massage chair is configured with back and bottom structures held up by a pair of legs. The various support bars and structure of the ergonomic massage chair may be comprised of, in typical implementations, metal, but plastic and other suitable structures are also possible. The back structure has perimeter support bars that form the base of the back support, and horizontal support bars extend from a left perimeter support bar to a right perimeter support bar. The bottom structure likewise has a perimeter support bar that forms the structure of the bottom. A horizontal support bar extends from a left perimeter support bar to a right perimeter support bar. Nodes are attached to the ergonomic chair, and stability balls fit inside openings created by the support bars and nodes. A cover having memory foam pillows therein encapsulates the chair to provide users with customized setups that suit them.

To realize a noble, useful seat with a simple structure designed to follow a natural movement of a seated person in front-rear and left-right directions and to support appropriately a movement of the person continuously changing its posture while the person balances a load. The seat includes the elastic support layer 3 and upper and lower base units 4 and 5 arranged to sandwich the elastic support layer 3. The upper base unit 4 includes the rolling surface 42e bulging toward the lower base unit 5 thereabove via the elastic support layer 3, is rollable in a 360° direction from the tilt reference position IRP in receiving a load of the seated person, and has a moving distal end side tilting more downward as a distance from the position IRP increases, and is configured to move while compressing the elastic support layer 3 by the rolling surface.

The present disclosure relates to a seat, comprising: a seat base; a seat frame; and a sitting posture detection device configured to alert a user when a sitting posture of the user sitting on the seat deviates from a standard sitting posture, wherein the sitting posture detection device includes: one or more distance sensors configured to measure a distance from the seat frame to one or more body parts of the user; and a processor configured to determine, according to the distance detected by the distance sensor, whether the sitting posture of the user deviates from the standard sitting posture, and issue an alarm information if the sitting posture of the user deviates from the standard sitting posture.
