A chair is provided comprising a seat assembly including a seat back and a seat bottom and a support frame including a left leg assembly and right leg assembly connected by a transverse support member. The seat back is pivotably connected to each of the leg assemblies such that an upper portion of the seat back pivots in relation to the leg assemblies between a first seat back position and a second seat back position. The seat bottom is rotatable in relation to the seat back between an upright position and a horizontal position. The seat bottom is slidingly engaged with the leg assemblies such that pivoting of the seat backward from the first seat back position to the second seat back position causes the seat bottom to slide forward from a first seat bottom position to a second seat bottom position.

A seat comprises a base assembly adapted to be fixed to the body of the vehicle, an articulated support assembly comprising front and rear support links for a seat cushion of the seat each of which has two ends articulated about axes which are respectively fixed relative to the seat cushion and to the base assembly, devices for adjusting the angular position of the support links relative to the seat cushion, and devices for controlling the position of a seat back of the seat relative to the seat cushion. The control devices comprise a convex or concave articulated quadrilateral, which has four corners, a first corner is connected to the seat cushion and the second and fourth corners are connected to the seat back.

A collapsible support frame includes a plurality of segmented legs pivotally connected to an inner surface of a collar, and are held together by an elastic cord. The legs pivot between a folded position and an deployed position. In the folded position, the legs segments form a bundle to facilitate storage or transport. Portions of the legs segments may seat within leg seats formed in the outer surface of the collar. In the deployed position, the legs pivot to contact leg support seats formed at angles in an inner surface of the collar. After contact, each leg extends in a different direction supported by its respective leg support seat. The elastic cord provides tension that keeps the leg segments together in the deployed position, and prevents the leg segments from becoming lost or separated in the folded position.

An ergonomic chair provides continuous support to the seated user throughout a broad range of postures by pivoting both the seat and back supporting cushions about a first or common axis disposed above the seat support cushion and in front of the back support cushion. The back supporting portion also independently pivots about a second horizontal axis proximate the lumbar region in a manner that allows the back supporting cushion to assume an angle that provides permanent contact with the seated user's back when said user is leaning back against the back support cushion. The springs that otherwise oppose the free rotation about the first and second axis are balanced such that the force inherently exerted by the user during movement through a range of seated postures is sufficient to initiate the coordinated rotation of the seat and back supporting element. No additional exertion is required once the user has reached the desired inclination, as the return springs are selected to counterbalance the redistributed weight of the user. Thus, full contact of the back supporting portion with the user's back is achieved over a full range of postures to provide proper ergonomic support, allowing the user to stay at task. In combination with such motion, which maintains the head at a level and angle such that the eyes can remain focused on their primary visual target without need to adjust the height, depth or angle of the target. The chair can offer armrests that support the forearms of the seated user to reduce the load carried by the arms, shoulders, neck and back and cooperate with the motion of the seat and back supporting elements to maintain ergonomically correct orientation of the hands to the keyboard or work surface.

The present invention provides an apparatus for use in sitting on a vehicle and a method for use in manufacturing a seat. The apparatus can include a base, a back secured with the base and a seat pan secured with the base. The seat pan can further include a first portion and a second portion, wherein the first portion is configured to pivot relative to the second portion, such that the first portion of the seat pan pivots allowing a distal end to pivot so that the distal end can be moved out of a relative alignment with the second portion. The seat pan can be movably secured with the base allowing the seat pan to move generally horizontally. The back can also be pivotably secured at with the base allowing a lower portion of the back proximate the seat pan to pivot.

A chair that can be mounted to a bleacher comprises a dual-pivot structure to enable movement of a seat between an up position, wherein the seat compactly fits within the bleacher envelope, and a down position, wherein the seat is substantially aligned with the bleacher and located at a suitable seating height. The chair includes single-piece, injection molded bleacher bases, which are composed of a “no-break”, fade-resistant plastic and include strategically positioned strengthening ribs. Additional embodiments of the chair comprise a clip-on bleacher base for removably mounting the chair to the bleacher and riser bases and floor bases that can be affixed to a riser portion and a floor portion, respectively, of a step structure.

A stackable chair that is capable of being ganged with a further like chair in side-by-side relationship, including an upper frame adapted to receive and support a seating platform, and a backrest platform for supporting a user seated on the chair. The upper frame is attached to a lower frame having a left and right sides, each said having a pair of leg members connected underneath the lower frame, each of the leg members having a lower end to engage the supporting surface for the chair, and having an upper end. The right legs connect to a right frame member attached to the lower frame right side. The left legs connect to a left frame member attached to the lower frame left side. A left side and a right side coupling support extend respectively on top of left and right frame members. The left side coupling support includes a left extension having a coupling hook extending outward. The right side coupling support includes a right extension having a lower surface enclosing a downward opening slot aligned parallel with the right side frame member. In a ganged setup, the left coupling hook of one chair is insertable into the right slot of the second chair of a like chair. The ganged chairs, when disassembled, can be stacked vertically for ease of transfer. The chairs provide rigid connections and compact configurations when ganged or stacked.

A vertical stacking leg-over-leg ganged chair is attachable side-by-side and includes an upper frame adapted to receive and support a seating platform, and a lower frame supporting the upper frame, and a backrest for supporting a user seated in the chair. The ganged chair includes a front pair of legs angled frontward, and a rear pair of legs angled rearward, each pair connected underneath the lower frame. The right legs are connected to a right frame member, and the left legs to a left frame member, with the left frame member being of a lesser length than the right frame member. In a side-by-side ganged setup, the wider spaced apart right legs of one ganged chair fit over the left legs of a second like chair, forming a single width leg unit on either side of the ganged chairs. Each upper portion of the left legs includes an elongated slot that accepts an elongated lug on the upper portion of each right leg, for connective support when chairs are attached horizontally. The configuration of legs, the angles of the legs, and the rearward angle of the backrest, allow the ganged chair to be stacked vertically for ease of transfer. The leg-over-leg structure allows connection side-to-side, providing a lesser overall width of chairs when in the ganged configuration.
