Abstract: The invention relates to a seat (1), in particular an office chair, comprising a seat support (3) for a seating surface (6) and comprising a backrest support (4) of a backrest (5), which is held on the seat support (3) so as to be able to move in a tiltable manner to the side, wherein the backrest support (4) comprises two support arms (4a, 4b) which are configured to be flexible and/or articulated laterally and spaced apart from one another. Preferably, the seating surface (6) and/or the backrest (5) comprises a curved seat shell and/or backrest shell (6a, 5a) provided with a cover (6b, 5b) with a number of flexible curved ribs (15, 16) on the edge of the shell, wherein the cover is stretched by the seat shell and/or backrest shell (6a, 5a) such that when the cover (6b, 5b) is loaded, the bending of the curved ribs (15, 16) is altered.

Abstract: The invention concerns a vehicle seat for a vehicle with a seating surface (10), a back rest (12) and at least one foot (14) supporting the seating surface (10), wherein the foot (14) is formed by a connecting means assembly (16) comprising two connecting means (18, 20), namely a first connecting means (18) and a second connecting means (20), each running/extending substantially horizontally, which are each coupled and held spaced in the vertical direction by means of two further connecting means (22, 24), namely a third connecting means (22) and a fourth connecting means (24), such that these four connecting means (18, 20, 22, 24) form a frame (26) which can be connected with the vehicle, and that at least one fifth connecting means is a deformation device (36), wherein the first connecting means (18) is arranged in the vertical direction above the second connecting means (20) and the third connecting means (22) is arranged in the vehicle longitudinal direction in front of the fourth connecting means (24).

Abstract: An office chair has a seating element with an upright tubular element (3) and a base, the seating element being connected to the base by means of the support element (1) so as to be swiveled and reset. Rubber buffers (19, 24) are provided between a connecting element (2) of the base, ring discs (11) and (17) and a tubular element (8) extending from the seating element downward and allow an oscillating movement of the seating element. The rubber buffers at least partially enclose the connecting element (2), thereby retaining the same. A pneumatic spring (4) allows to adjust the height of the seat. A thumb screw (16) allows to adjust the restoring force by compressing the rubber buffers (19, 24) to a greater or lesser extent.

Abstract: A seat comprising an underframe and a seat element wherein the seat element comprises a front seat part, a rear seat part, a lower backrest part and an upper backrest part wherein the seat element can be displaced from a basic position into a reclined position, and wherein the seat element comprises at least one supporting arm composed of at least one upper support and at least one lower support having an arcuate profile in a transitory region between the rear seat part and the lower backrest part, and wherein the upper support and the lower support are connected at an upper backrest part. At least one guide element guiding the upper support in a front region of the seat part, and at least one connecting link positioning the upper support and the lower support with respect to each other. The front seat pan: being capable of being pulled back by the upper support when the backrest parts are loaded by an individual leaning against them.

Abstract: A chair having a seat, a first support base and an upright elongated support element. The upright elongated support element has a first point and a second point, with the first point connecting to the seat and the second point connecting to the first support base. The first support base is bolstered by a resilient component since the resilient component is disposed beneath the first support base. The resilient component is capable of providing cushioning to the first support base is also capable of providing a full axial rotation to said upright elongated support element.

Abstract: There is provided a chair (101) comprising: a seating portion (102) for occupation; a base portion (103) for location upon a support surface; and a connecting portion (104) connectedly extending between said seating portion (102) and said base portion (103); wherein said connecting portion (104) is configured to provide a degree of freedom of the position of said seating portion (101) relative to said base portion (103), such that said seating portion (102) is movable between a default unloaded position relative to said base portion (103) and each of a plurality of available loaded positions relative to said base portion (103), whereby when unoccupied, said seating portion (102) is in said default unloaded position relative to said base portion (103), and when occupied, said seating portion (102) is in one of said plurality of available loaded positions relative to said base portion (103), whereby said chair is configured to dynamically respond to changes in the posture of an occupant.

Abstract: A spring chair (cushion) structure in which the spring chair (cushion) structure, elastic body, flexile rods have sufficient pliancy and, furthermore, are slanted at equal intervals apart such that they conjoin two frame members into a single structural entity. When sitting in the spring chair (cushion) structure, body weight is utilized to directly cause the torsional resiliency of the elastic body to produce an appropriate spring-loaded and buffered effect.
