The present invention relates to a seat frame, including a lower base; an upper base; and a plurality of rotating devices disposed on the upper base or the lower base and including at least one rotating device capable of horizontally rotating the lower base relative to the upper base. The lower base is connected to the upper base. When the rotating devices make the lower base horizontally rotate relative to the upper base, the upper base and the lower base do not fall off each other. A plurality of connecting devices are disposed on the upper base. The present invention eliminates the noise generated in the rotating process; and a telescopic support enables the size of the seat frame to be adjustable, the installation is simple and convenient, the use effect is good, and it is more stable and is suitable for popularization.

A quick-release device for securing a gas cylinder in a seat plate includes a pedestal defining a socket for receiving the gas cylinder. The pedestal projects upwardly from an endwall to form a jaw against which the gas cylinder is received when applied to the socket. A clamp is pivoted to the jaw for movement between an open position and a closed position. A flange is formed in the pedestal and has a lower surface for confrontation with the seat plate. A latch is coupled to the pedestal. The latch moves between a first position enabling movement of the clamp between the open and closed positions, and a second position disabling movement of the clamp between the open and closed positions.

A rotary hanging chair comprises a cushion, a support frame and a base assembly. The cushion has two ends connected to an upper end of the support frame and is able to swing forwards and backwards with respect to the support frame. A bottom of the support frame is connected to the base assembly and is able to rotate within 360° with respect to the base assembly. The entire rotary hanging chair comprises three detachable parts, thus being simple and practical in structure, not only can swing forwards and backwards like a traditional hanging chair, but also can rotate within 360° to change the direction freely to meet the requirement for switching the view angle, and is small in size, easy to carry and capable of being used both indoors and outdoors.

The present invention relates to ergonomic supports in medical environment. In order to provide improved ergonomic support while providing a minimum impact of the user's activities, an ergonomic support device (10) for users in medical environment is provided. The support device comprises a seating support arrangement (14), an X-ray shielding arrangement (18) and a base support structure (12). The base support structure provides mechanical support for the seating support arrangement and the X-ray shielding arrangement. The seating support arrangement comprises a seat support surface (16) that is configured for supporting a buttocks area of a user. The X-ray shielding arrangement comprises at least one X-ray shield (20) that is configured for shielding at least a part of an X-ray radiation to which a user is exposed to while supported by the support surface. The at least one X-ray shield is movably mounted to the base support structure to be adjustable in its position relative to a user at least partly resting on the seat support surface.

A chair for particular use in clinical or hospital environments has a frame to which a support material is secured. The support material may form a chair back and/or a seat for the chair to provide support to the chair occupant. The support material may be made from a textile of interwoven strands wherein some of the interwoven strands include copper containing particles such as copper iodide or copper oxide within the textile fibers.
