A chair, in particular an office chair, is described. The chair has a backrest that is inclinable with regards to a seat carrier via a backrest carrier. The chair has a seat surface that can be moved synchronously with the backrest and is supported on the seat carrier via at least one seat link. A coupling link is provided for synchronization between the movement of the backrest and the movement of the seat surface. The coupling link is connected rotatably, on one side to the seat surface and, on another side, to the backrest link.

1. A chair, comprising: a seat carrier; a backrest carrier; a backrest supported on said backrest carrier for inclining said backrest relative to said seat carrier; a seat surface having a front half and a rear half; at least one seat link including both a front, first seat link and a rear, s
1. A chair, comprising: a seat carrier; a backrest carrier; a backrest supported on said backrest carrier for inclining said backrest relative to said seat carrier; a seat surface having a front half and a rear half; at least one seat link including both a front, first seat link and a rear, second seat link, said seat surface being connected rotatably to said seat carrier through said front, first seat link and said rear, second seat link, said seat surface to be moved synchronously with said backrest and supported on said seat carrier through said at least one seat link; a coupling link for synchronization of a movement of said backrest and a movement of said seat surface, said coupling link connected rotatably, on a first side, to said seat surface and, on a second side, to said backrest carrier; said front, first seat link being disposed in an inclined manner in a region of said front half of said seat surface, said front, first seat link connected rotatably to said seat surface around a first point of rotation and, said front, first seat link also connected to said seat carrier around a second point of rotation, a distance between the first point of rotation and said backrest being smaller than a distance between the second point of rotation and said backrest; and said rear, second seat link being disposed in an inclined manner in a region of said rear half of said seat surface, said rear, second seat link connected rotatably to said seat surface around a third point of rotation and also connected to said seat carrier around a fourth point of rotation, a distance between the third point of rotation and said backrest being smaller than a distance between the fourth point of rotation and said backrest. 2. The chair according to claim 1, wherein an inclination of said rear, second seat link is greater than an inclination of said front, first seat link. 3. The chair according to claim 1, wherein said coupling link has points of rotation, and at least one of the points of rotation of said coupling link is provided in a rear half of said seat surface, said rear half being directed toward said backrest. 4. The chair according to claim 3, wherein one of the points of rotation of said coupling link coincides with the third point of rotation. 5. The chair according to claim 1, wherein if said backrest is not in an inclined position, said rear, second seat link is inclined by an angle β=(45±30)° in relation to a vertical.
