A seat has a seat surface element and a first backrest element. The first backrest element can be pivoted from a use position into a stowed position under the seat surface element. The first backrest element can be pivoted under the seat surface element in a guided or optionally in a forcibly guided manner.

A seating unit such as a chair, daybed, love seat or sofa. The seating unit includes a base adapted to provide a seating surface for a user and a seat back adapted to provide a surface for supporting a back of the user. A flexible joint connects the seat back as a cantilever to the base creating a horizontal pivot adapted for rotating the seat back along its Z-axis between a first stowed position and a second deployed position while substantially preventing movement of the seat back along its X-axis and Y-axis. In one embodiment, the base is a split base comprising a first portion and a second portion foldable for storage and shipping and unfoldable for use.

A multifunctional grandstand chair includes a chair frame, a cushion movably arranged on the chair frame, and backrest cloth. The chair frame includes a base frame, a backrest tube and two foot supports, which are respectively pivoted to two sides of the base frame and capable of being inwards folded onto the base frame or outwards unfolded to support the base frame. The multifunctional grandstand chair further includes fixed connecting pieces connected between the base frame and the foot supports to limit the maximum unfolding angle of the foot supports. When the multifunctional grandstand chair needs to be transformed into a grandstand chair structure, the foot supports are folded onto the base frame. When the multifunctional grandstand chair needs to be transformed into a common chair, the foot supports are unfolded to be supported on the ground.

a foldable backrest, including a backrest plate, operatively configured to be leaned upon by a back of a user. A support plate pivotally connected to the backrest plate operatively configured to be placed on a surface on which a user desires to sit or lay down on. One or more movable rigid wedges configured to form a desired angle between the backrest plate and the support plate in respect to the pivot connection between the backrest plate and the support plate. One or more wedge-stopping means for fixing the movable rigid wedge in a position for forming the desired angle. The one or more movable rigid wedge(s) configured to transfer mechanical support to the backrest plate from a surface on which support plate is positioned when the rigid wedge is fixed in a desired position by the wedge-stopping means.

A portable chair apparatus for assisting the user with comfort, storage, and transportation includes a base, a seat with an opening, a storage compartment between the base and the seat, a back support column, a lumbar support piece, a handle, and a light. The back support column is adjustable relative to the seat between an open and closed position. The lumbar support piece is adjustable along the back support column and is sized to fit within the opening of the seat when the back support column is in the closed position. The light is on the top surface of the back support column. The chair can further include a handle having a light directed towards the space in front of the user when holding the chair. Other embodiments are described.

A chair is provided having at least one leg with an upper end on which a seat component is supported and a backrest interconnected to and projecting from the seat component. The backrest comprises a lower backrest section, an upper backrest section, and a backrest hinge interconnecting the upper backrest section to an upper end of the lower backrest section. The lower backrest section is interconnected to and extends from a rear portion of the seat component and the backrest hinge is configured to permit the upper backrest section to be located in an upright position in which the upper backrest section projects above the lower backrest section and is configured to permit the upper backrest section to be pivoted to a forward position in which the upper backrest section extends laterally over and spaced above the seat component.

The purpose of the present invention is to provide, in a vehicle seat having a walk-in mechanism, a locking mechanism for a seat back with which rotation of a lock plate can be suppressed against impact in any direction, and with which the locked state can be more reliably retained. In order to achieve the foregoing, provided is a vehicle seat having a walk-in mechanism, wherein: a reclining unit having the walk-in mechanism comprises a swing plate and latch for locking a seat back at a seated posture position; the latch has a structure that rotates about a latch rotating shaft, locks rotation of the seat back by meshed engagement with the swing plate, and releases the lock when the meshed engagement with the swing plate comes out; and the latch is given a structure with which a counter plate is added to the opposite side from the position of meshed engagement with the swing plate, relative to the latch rotating shaft, and the center-of-gravity position of the latch is brought close to the center of rotation of the latch.

A folding chair includes front and rear supports that fold and/or retract into central beams to reduce the space occupied by the chair in a folded configuration. A backrest is coupled to the central beams with a hub that allows an angle of the backrest relative to the central beams to be selected and for the backrest to be folded flat relative to the central beams. One or more actuators and pin actuators may control the relative movements of the backrest, front support, rear support, and central beams.

A lightweight, portable, and compact combination chair and equipment caddy. The combination chair and caddy is accomplished by using a standard five or six gallon bucket together with an integral seat and back rest. The back rest is movable between an extended position for supporting a user's back when seated on the bucket, and a retracted storage position. When the back rest is in its storage position, it is retracted almost completely within the interior of the bucket to enable easy carrying of the bucket via its handle. The back rest also uses the handle of the bucket to hold it in its extended position thereby keeping costs and materials to a minimum.

A modular sofa assembly described herein includes a plurality of seating modules each having a seat section, a backrest section, and side edge surfaces. The backrest section includes first and second portions coupled for movement between a folded configuration and an extended configuration. An armrest module has an armrest side edge surface configured for mating engagement with a side edge surface of a seating module. The modular sofa is assembled by aligning connectors of the seating modules and armrest module, with each respective connectors slidingly engaged along an axis. After bringing the modules together, these connections are secured with the side edge surfaces in abutting engagement. The modular sofa further may include a power cradle mounted at the sofa's bottom surface. The power cradle includes a cubic power outlet near the front of the sofa, and power cable extending beyond the back of the sofa.
