Abstract:
A mechanism is provided for an office chair. In order to accomplish an advantageous motion characteristic of the mechanism and thus of the office chair, a synchronized mechanism provides a correlated seat/backrest movement of an office chair. The backrest support is connected to the seat support not directly and immediately, but via a coupling element. The force applied to the seat support upon swiveling the backrest support is applied to the seat support solely via the coupling element. Two guide element pairs are provided to guide the seat support relative to the base support.

Claim (Index 1):
A synchronized mechanism for a correlated seat/backrest movement of an office chair, the synchronized mechanism comprising:\n a base support mountable on a chair column; a seat support disposed on said base support and movable relative to said base support; a coupling element; a backrest support connected to said seat support, wherein a swiveling of said backrest support produces a movement of said seat support relative to said base support, wherein said backrest support able to swivel about a transverse axis is articulated directly to said base support, wherein said backrest support is connected to said seat support via said coupling element; said coupling element is articulated both to said backrest support and to said seat support, wherein a force applied to said seat support upon swiveling said backrest support is applied to said seat support solely via said coupling element; first guide elements disposed on said base support; second guide elements disposed on said seat support, wherein one of said first guide elements and one of said second guide elements cooperate to form a guide element pair such that the swiveling of said backrest support produces a movement of said one second guide element along said one first guide element and thus a movement of said seat support relative to said base support; and said first and second guide elements forming two guide element pairs disposed, spaced apart from each other in a chair lengthwise direction, and including a front guide element pair looking in the chair lengthwise direction and a rear guide element pair looking in the chair lengthwise direction.
