A foldable multifunction chair including a base for contacting a support surface; a user body support having a support front surface for contacting a user body, the user body support being adjustably pivotably mounted to the base along a transversal axis; a selectively adjustable chair deployment mechanism cooperatively coupled to the base and the user body support, the chair deployment mechanism being configured for selectively adjusting the user body support to a desired angle relative to the base; and a locking mechanism configured for angularly locking the user body support to the desired angle relative to the base. The chair may be used, e.g., as a backrest with an accessory support positioned in front thereof for work, or as a seated workstation wherein the accessory support is positioned adjacent a rear surface of the user body support in a deployed position, and the collapsible seat in a deployed position.

A reversible seat for a vehicle includes a seat structure, a support, and a pivot. The support has a slot formed therein, and the slot has an arcuate shape over a portion of the slot. The pivot is connected to the seat structure and engaged with the slot. The seat structure is configured to move from a first orientation to a second orientation by moving the pivot from a first end of the slot towards a second end of the slot and rotating the seat structure about a pivot axis of the pivot. The seat structure is also configured to move from the second orientation to the first orientation by moving the pivot from the second end of the slot towards the first end of the slot and rotating the seat structure about the pivot axis of the pivot.

A lounge chair includes a support structure that is designed to allow the chair to be positioned in a forward facing position, and also be flipped rearwards so that it can be usable as a chair when facing in a rearward position.

A multi-positional chair assembly comprises a frame portion defined by a pair of sinuously-shaped bars. The frame portion includes a back support section, a middle section, and a buttocks support section. The sections are joined at multiple junctions defined by a bowed shape. A resilient panel traverses the pair of sinuously-shaped bars, providing a supportive surface for a user. The panel may include a resilient metal sheet, apertures, or parallel strips of material. The frame portion can be positioned in multiple positions to provide a sitting surface, including a lounge chair position and a higher elevated stool position. The chair assembly reconfigures between the lounge chair position and the stool position through rotation. Rotating the buttocks support section and the legs to engage the ground surface achieves the lounge chair position. And rotating the back support section and the legs to engage the ground surface achieves the stool position.

A wheeled device that converts between a multi-mode beach chair and a standard vertical dolly. It can also be used as a flat 2-wheeled wagon. A rigid frame includes at least two parts coupled by hinges, a first part (long part) that can fold to different lengths, and a second part (short part). There is a swiveling top handle on the end of the long part, and a swiveling bottom handle on the end of the short part. In a long chair mode, the long part is fully extended; in the short chair mode, it is folded and In the dolly mode, the short part forms the bottom of the dolly.

A back rest assembly includes a base assembly mountable adjacent a resting surface and a back rest having a supported side pivotably supported by the base assembly and an unsupported side spaced laterally apart from the supported side along a lateral axis. When the base assembly is mounted, the back rest is positionable over the resting surface and selectively pivotable about the lateral axis for adjusting an angular position of the back rest relative to the resting surface.

The assembly chair includes a pair of frames, a plurality of coupling rods, a plurality of pairs of depressed portions, at least one support member, and a sheet. The sheet is removably installed between the support member and the coupling rod. At least at one end portion of the sheet, the sheet includes a plurality of inserted portions along a width direction of the sheet. A flat plate is passed through at least one of the inserted portions. The support member with a flat intermediate portion is passed through another one of the inserted portions. The sheet is wound around outer peripheries of the inserted portion through which the plate is passed and the inserted portion through which the support member is passed to adjust a length of the sheet. In such state, the support member has both end portions fitted to the depressed portions on the frames.

A seat positioning system includes a base frame having a pair of forward slots and a pair of rear slots, and a seat frame having a front end and a back end. The seat frame is coupled to the base frame and movable relative to the base frame. A first pair of linkages is slideably coupled to the pair of forward slots and connects the frames. A first pair of locking devices has a locked configuration adapted to prevent the first pair of linkages from sliding relative to the pair of forward slots and an unlocked configuration adapted to allow the first pair of linkages to slide relative to the pair of forward slots. A second pair of linkages slideably is coupled to the pair of rear slots and connects the frames. An actuator is pivotally connected to both the seat frame and the base frame and is configured to extend and contract to move the seat frame relative to the base frame.

An adjustable chair includes upper and lower base members, a seat assembly secured to the upper base member, and a chair adjusting mechanism. In an embodiment the upper base member is connected to the lower base member by first and second linking members each having a first end connected to the lower base member and a second end slideably received in corresponding first and second arcuate tracks disposed in the upper base member, such that movement of the second ends into and out of the tracks results in vertical movement of the seat assembly relative to the base. In a further embodiment the seat bottom and seat base comprise cooperating arcuate rails, tracks, and/or bearing members, where cooperative action of the arcuate rails, tracks, and/or bearing members enables the seat bottom to tilt relative to the seat base. In a further embodiment the seat bottom and seat back comprise cooperating arcuate rails, tracks, and/or bearing members, where cooperative action of the arcuate rails, tracks, and/or bearing members enables the seat back to recline relative to the seat bottom.
