Abstract: A chair comprising a supporting structure (12) having a pair of front legs (20a) and a pair of rear legs (22) and carrying a seat (14) and a backrest (16). The supporting structure (12) comprises a transverse element (18), a first pair of bars (20) fixed to the ends of the transverse element (18) and forming the pair of front legs, and a second pair of bars (22) fixed to the ends of the transverse element (18) and forming the pair of rear legs.

Abstract: An armrest of a chair which can be adjusted and which can be moved in a transverse horizontal direction with respect to the longitudinal direction of the armrest. Regardless of the position thus obtained, the armrest is capable of turning on an essentially vertical axis between two extreme positions, so to adapt to the specific needs of the user and to the activities to be performed in an optimal way.

Abstract: A chair comprising a base structure (22) bearing a seat (32), backrest (36), and a writing table (42) which can be moved between a lowered, inoperative, position, and a raised, operative, position. In the aforesaid lowered, inoperative, position, the table (42) is inclined with respect to a vertical plane (A) parallel to the longitudinal plane of symmetry of the chair, in such a way that two or more chairs of the same type can be set longitudinally against one another, with the tables of two adjacent chairs partially overlapping one another.

Abstract: Chair with a seat and back tilting in a synchronized way, includes a base structure (14), a seat support structure (18) provided to the base structure (14) about a first transverse axis (22), a back support structure (20) pivoted to the base structure (14) about a second axis (24) parallel to the first, an articulation assembly (48) capable of synchronizing the tilting movements of the seat and the back with each other, an elastic device (32) tending to push the seat (12) and the back (16) towards a forwardly inclined position and tending to oppose rearward tilting of the seat (12) and the back (16), a device to selectively stop the forward tilting travel of the seat and the back in a normal sitting position and in a forwardly inclined position, and a device to immobilize the seat (12) and the back (16) in at least one operating position.

Abstract: Tilting seat chair, comprising: a base structure (16) bearing a transverse tilting axis (24), a seat support structure (14), tiltably mounted about the transverse tilting axis (24), an elastic arrangement for opposing the seat tilting motion, and an adjustment device (42) for varying the force opposing the elastic arrangement. The aforesaid elastic arrangement comprises a torsion bar (32) connecting the seat support structure (14) to the base structure (16) in a tilting manner about the transverse tilting axis (24). The torsion bar (32) has at least a first portion (32a) rotatably connected to the seat support structure (14) and at least a second portion (32b) connected to the base structure (16) through the aforesaid adjustment device.

Abstract: A combination tablet and armrest assembly for a seating unit. The seating unit includes a seat portion and a back, and the combination tablet and armrest assembly includes a support member which is movable between an operative position toward the front of the seat portion, and an inoperative position toward the rear of the seat portion. The support member is preferably mounted for pivoting movement to a base member secured to the underside of the seat portion. A combination tablet/armrest member is mounted to the support member. The tablet/armrest member includes a stationary section mounted to the support member, and a pivotable section interconnected with the stationary section via a hinge. The sections of the tablet/armrest member are adapted to be folded together when the support member is in its inoperative rearward position, to function as an armrest.

Abstract: A chair, in particular a chair for office use, comprising:

Abstract: A chair with seat and backrest that oscillate in a synchronized way, comprising:

Abstract: A chair arm-rest comprises a rear portion secured to the supporting structure of the arm-rest, and a front portion which is pivotally mounted to the rear portion around an axis substantially parallel to the longitudinal direction of the arm-rest and adapted to assume two different operative positions which are spaced from each other by about 180.degree.. The articulation axis is offset towards one side of the rear portion of the arm-rest, so that in one of said two operative positions the front portion projects towards the inner side of the arm-rest with respect to the rear portion, so as to provide adequate support for the arm of the occupant when the latter must perform an operation at the keyboard of a typewriter or a computer.

Abstract: A chair arm-rest, particularly for an office chair, includes a supporting structure and an arm-rest structure movable relative to the supporting structure by movement of a user's forearm resting on the arm-rest between a shortened condition and a forwardly extended condition, in which the arm-rest can support the user's forearm better, for instance when performing a typewriting operation.

Abstract: The sofa according to the invention can be converted into bed by drawing forwardly the supporting structure until it reaches an elongated condition in which the mattress lies down thereon. In the retracted condition for use as sofa, the mattress is folded under the supporting structure.
