A folding chair includes left and right frame rods, left and right frame rotating elements, left and right rear leg sliding elements, left and right rear leg rods, left and right rear leg fixing elements, left and right back rest rods, left and right back rest rod sliding elements, left and right front leg rods, leg terminals, left and right connecting rods, left and right handrail rods, left and right handrail fixing elements, left and right handrail supporting rods, left and right supporting rod sliding elements, limiting elements, left and right sliding elements, supporting rods, pad portion and back rest portion. The folding chair is compact and portable when folded and demonstrates high stability and high load-bearing capability when unfolded.

The present invention relates to a innovative magnetic tension lock(MTL) control system which guides the MagLev module in both vertical and horizontal movement. The MagLev module moves on its inherent magnetic force and is guided by the MTL control system. The MagLev module with MTL control system can be used in products of various applications. It can be made at efficient cost to perform unique function. It can provide magnetic cushioning, which is great for seat, bed and other body-supporting furniture. It can also be applied as a cushioning layer against outside impact, thus it can be mounted onto the surface of heavy duty equipment or even the vessel sailing in icy water. It functions on its magnetic energy for load capacity and only requires compact battery power for its MTL control system. Thus it saves energy and reduces impact on the environment. It can replace the traditional MagLev module that runs on electricity otherwise.

An apparatus that supports a user in a variety of positions to comfortably perform tasks, such as applying one or more tattoos to skin of a subject is herein disclosed. The apparatus can be reconfigured to optimally position and support the arms and/or chest of the user. A method for using a stool can involve rotating armrests of the apparatus from a stowed position to a deployed position. The armrests can support the user's forearms while supporting the user's chest such that the user can comfortably perform tasks in front of a chest support of the stool.

A pneumatic device for adjusting a contour of a seating face of a vehicle seat is disclosed. The pneumatic device includes a first foil; a second foil arranged on the first foil; a third foil arranged on the second foil; a first seam connecting the first foil, the second foil and the third foil to one another, wherein the first seam is configured to provide a first fluid chamber between the first foil and the second foil, a second fluid chamber between the second foil and the third foil, and wherein the first fluid chamber and/or the second fluid chamber are configured to adjust the contour of the seating face of the vehicle seat. The pneumatic device further includes a connection passage formed in the second foil and configured to fluidly connect the first fluid chamber with the second fluid chamber.

A lumbar support device for a vehicle seat permits vertical and fore-aft adjustment of the support or forces exerted on the back of an operator seated on the vehicle seat. The lumbar support device includes a lumbar panel resiliently flexibly attached to the seat frame and/or seat shell to permit fore and aft movement of the lumbar panel relative to the seat back, the lumbar panel arranged to bear against the seat back, and a cam element having a cam surface bearing against the lumbar panel to apply force to the lumbar panel toward the seat back, the cam element supported on the seat frame and/or seat shell for movement relative to the lumbar panel and relative to the seat shell and/or seat frame, the cam element configured to vary the force applied to the seat back based on the movement of the cam element.

A sliding stop switch may include a first rod extending in the longitudinal direction thereof, a second rod coupled to the first rod such that one end portion thereof is slidable in the longitudinal direction of the first rod, and a switch member coupled to the first rod to slide in the longitudinal direction of the first rod and to be fixed at a plurality of points on the first rod to stop the sliding of one end portion of the second rod.

Travel pillows include anchor mechanisms. The travel pillows can include anchor mechanisms with anchor bodies such as straps. The anchor bodies can be attached to the travel pillow body, such as to the rear of the travel pillow body, or alternatively can be detachable from the travel pillow body. The anchor mechanisms can also include loops through which the anchor bodies can pass before reattaching to themselves or attaching to another element such as a cover of the travel pillow body. The anchor bodies can be placed around a portion of a headrest, such as headrest wings, to prevent or make less likely a user's head and/or body fall forward inadvertently.

A connection assembly for a backrest, of an office or conference chair, includes a backrest structural element, a transverse support element, a transverse bearing by means of which the backrest structural element is rotatably coupled to the transverse support element in a direction perpendicular to a transverse direction, and a connection portion connecting the transverse support element to the backrest structural element, arranged and formed so that the backrest structural element is resiliently movable relative to the transverse support element.

Passenger seat assemblies including net backrests are described. An example passenger seat assembly can include a lower frame (14) configured to support a seat bottom (36) of the passenger seat. The passenger seat assembly can also include a backrest frame (18) attached to the lower frame (14) and configured to support a backrest assembly. The backrest assembly can include a backplate (16) disposed adjacent an aft side of the backrest frame (18). The backrest assembly can also include a net material (22) attached to the backplate (16) at a first attachment location (46a) on an aft surface of the backplate (16), extending around a forward side of the backrest frame (18), and attached to the backplate (16) at a second attachment location (46b) on the aft surface.
