    摘要： The adjusting mechanism serves for the setting of a restoring force acting on the backrest of a chair. A back support and a seat support are fastened on a support. A setting mechanism configured in the manner of scissors is provided for the weight setting. Said setting mechanism has two scissor arms which are connected to one another via a scissor pin. One of said scissor arms is formed by a spring element and is fastened with its front-side spring end on said support. The back spring end is fastened on said scissor pin. Said first scissor arm is connected to said back support in the manner of a connecting rod. An active lever length is defined between said scissor pin and a support pin about which said back support is mounted pivotably. A compact construction mode is achieved by the configuration of said scissor arm as a spring element.

    摘要： A chair chassis includes a base, a warped plate, a first adjustment member and a second adjustment member. The base including an upper cover, a lower cover and a front cover is arranged at a bottom surface of a seat of a chair. The warped plate is disposed under the upper cover of the base for connecting to a seat back of the chair. Two compression springs arranged in parallel with a certain interval are disposed between the first adjustment member and the warped plate for adjusting travel distance of the compression springs and changing a force of the seat back. The second adjustment member is used for lifting the chair by rotation of a second adjustment shaft. The chair chassis is fastened and adjusted by operating the second adjustment shaft to move along an axial direction. The chair chassis has simple structure, easy operation and improved applicability.
