  • Publication number: 20020167209
    Abstract: The chair, particularly an office chair, has a backrest articulated to a seat support by way of a rest support. A seat surface is movable synchronously with the backrest. A front region of the seat surface is connected to the seat support via a sliding guide and a rear region is connected to the seat support via a seat link. A distance from an upper pivot point, which connects the seat link to the seat surface, to the backrest is shorter than the distance from a lower pivot point, which connects the seat link to the seat support, to the backrest. The movements of the backrest and of the seat surface are synchronized by a sliding guide provided between the seat link and the rest support.

  • Publication number: 20020167208
    Abstract: A chair, in particular an office chair, has a backrest that is articulated on a seat carrier via a backrest carrier, and has a seat surface that can be moved synchronously with the backrest. The front region of the seat surface is connected to the seat carrier via a sliding guide. The rear region of the seat surface is connected to the seat carrier via a seat link. A top point of rotation connects the seat link to the seat surface. A bottom point of rotation connects the seat link to the seat carrier. The distance between the top point of rotation and the backrest is smaller than the distance between the bottom point of rotation and the backrest. A sliding guide for the seat surface is provided in the backrest carrier for synchronizing the movement of the backrest and the movement of the seat surface.

  • Publication number: 20020043864
    Abstract: A footrest is fastened via a telescopically extendable connecting element to an office chair, in particular to an office chair having a backrest that can be tilted into a rest position. This results in an especially comfortable and ergonomic seating position, and in particular a situation in which the office chair is pushed away from the footrest when the footrest is not needed.

  • Publication number: 20020017748
    Abstract: A longitudinal adjusting element has a housing (1) which is filled with a pressurizing medium and in which a piston (12) including a piston rod (16) is guided displaceably. The housing chambers (13,14) which are separated from each other by the piston (12) can be connected with each other or separated from each other with the assistance of a valve device (17). The valve device (17) has at least two overflow ducts (16,40) [sic. (26,40)] which have different throttling effects and which take effect jointly or successively while valve pin (29) is slid in to varying extents.
