  • Publication number: 20150196124
    Abstract: A chair having a seat element includes, on both sides of the seat element, in relation to a vertical longitudinal center plane of the chair, one chair leg element in each instance. Each chair element, forms two chair legs, as well as a coupling unit for interlinking the chair with a chair of the same design. The coupling unit is formed by a first connection element, which connects the chair legs of one chair leg element to each other at their lower ends, and by a second connection element, which connects the chair legs of the other chair leg element to each other at their lower ends. The first connection element of the chair can be interlocked with the second connection element of the chair of the same design for interlinking the two chairs.

  • Publication number: 20100117421
    Abstract: The invention relates to a backrest for a chair, comprising: an external backrest frame (1) that has two backrest frame legs (11, 12); an internal (H-shaped) stretching frame (4) that has two lateral stretching frame legs (41, 42) between which a flexible covering (44) and an extensible and compressible (convex) stretching frame transversal connection (43) are arranged; and at least one hand wheel (6a, 6b) that is disposed externally on a backrest frame leg (11, 12) and is fitted with a threaded bar (61) which extends through the backrest frame leg (11, 12). The threaded bar (61) allows the adjacent stretching frame leg (41, 42) to be pulled closer such that the stretching frame transversal connection (43) is extended and the flexible covering (44) is stretched while allowing the adjacent stretching frame leg (41, 42) to be moved away such that the stretching frame transversal connection (43) is compressed and the flexible covering (44) is slackened.
