The invention relates generally to a lightweight, collapsible, and portable wheeled seat, e.g., a wheeled office chair or stool, for travel, storage, and mobility. The seat includes a seat base member and a seat surface member collapsible between an open, extended position, which is configured to provide a seating surface, and a collapsed, closed position. The seat surface member includes a central seating surface member fixed to the seat base member that has an outer perimeter, and a pair of oppositely disposed and generally u-shaped seating surface members pivotally secured to the seat base member. Each of the generally u-shaped seating surface members include a pair of leg portions that extend from a base portion thereof, or an inward directed perimeter and a portion of each inward directed perimeter has a shape that substantially complementarily corresponds to a shape of a portion of the outer perimeter of the central seating surface member.

An ergonomic chair (300) comprising a seat (310), a lower leg support (320), a chest support (330), and a hip support (360); the seat (310) for supporting the posterior thigh (11) and/or buttocks (12) of a seated user (10), the seat (310) being configured to urge the hip of a seated user (10) in a forward direction; the lower leg support (320) for supporting the anterior side of the lower legs (14) of the seated user (10); the chest support (330) for supporting the chest (15) of the seated user (10) in a forward leaning position of the seated user (10); the hip support (360) is configured to support the anterior hip of a seated user (10) as the seat (310) urges the seated user's (10) hip forwardly towards the hip support (360).

According to the present invention, we present a system employed in the manufacture of furniture requiring plastic fabric rotary assembly meshes comprising a plurality of parts that can be used repeatedly, as all of them are made up of first male locking elements and second female locking elements that do not require extraneous fastening elements for their placement.

A portable therapeutic unit and system for treating a back, a neck, or the back and the neck of a user is disclosed. The therapeutic unit includes a first seat, a back support, a hinge, and a metal back. The first seat is designed for the user to sit thereupon. The back support is designed to support a back of the user. The hinge pivotally connects the first seat and the back support. The metal back is connected to the back support, with the metal back magnetically coupling with an attachment magnet. Further, the attachment magnet couples to a therapeutic aid to deliver treatment to the user.

A structure includes a first body member including a first interfacing side edge and a first interconnecting component at the first interfacing side edge and a second body member identical to the first body member, the second body member including a second interfacing side edge and a second interconnecting component at the second interfacing side edge. The first interconnecting component engages with the second interconnecting component to secure the first body member and the second body member together.

The first interconnecting component engages with the second interconnecting component to secure the first body member and the second body member together.

The vehicle seat includes: a seat cushion; a seat back; a lifter link mechanism wherein the seat cushion is displaced by a sector gear being displaced; and a speed reducer-equipped motor including a pinion gear engaging with the sector gear; and a first and second restriction portions that stop the rotation of the pinion gear to one side. The sector gear is displaced to one side by the pinion gear being rotated to one side. The displacement of the sector gear to one side is stopped by the rotation of the pinion gear to one side being stopped by the first and second restriction portions. The sector gear is displaced to the other side by the pinion gear being rotated to the other side. The rotation of the pinion gear to the other side is stopped by the displacement of the sector gear to the other side being restricted.

Disclosed is a fastening structure for a seating foam, comprising a foam and a reinforcement fabric, and characterized in that the fastening structure is directly provided at a reinforcement fabric at a location corresponding to a fastening position, and is connected to the reinforcement fabric. The fastening structure of the present invention simultaneously meets two functional requirements of a foam, namely reinforcement of a side B of the foam and fastening of an exterior side A of the foam. The novel fastening structure of the present invention saves space, is thin and light, enhances the strength of the foam against a pull-out force, and optimizes a foam production process.

A system for supporting the human body or a human body segment is provided. The system comprises a base element having a substantially flat shape, and one or more pluralities of shaped modular elements. The base element is flexible, so that it can be brought from an operating, extended configuration to a non-operating, folded configuration. The support system comprises one or more stiffening elements, which are designed in such a way that, on the one hand, they provide the correct stiffness to the backrest when in the operating configuration, and, on the other hand, they do not prevent the possibility of folding the backrest when in the non-operating configuration. The support system can, for example, be made in the form of a seat, a backrest, a mattress, or the like.
