Chair.

p0001The invention relates to a chair with seat support to which a seat is attached which is connected via a link to the seat support and consists of a front seat part and a hinged thereto rear seat part, a back rest carrier is hinged to the seat carrier.

p0002In a known chair of this kind, it proves disadvantageous that the backrest when Stizeen unintentionally easily evades at a soft setting. In addition, it is disadvantageous in this known solution that backwards the distance between the backrest support and the backrest and the rear edge of the seat when pivoting the backrest.

p0003Starting from this prior art, the invention has the object to provide a chair of the presupposed as known type such that a substantially constant distance from the trailing edge of the rear seat part is adhered to the pivoting of the backrest.

p0004This object is inventively characterized in that the front seat part is mounted on a front handlebar on the seat support and the rear seat part through a rigidly associated, rearward approach on which a bearing one end of an arm is fixed, the other end is connected via a bearing with a portion of the backrest support, a power storage is hinged on one hand to the seat carrier and the other part to the seat.

p0005The chair according to the invention ensures that the distance of the seat from the backrest practically over the entire pivoting range remains the same.

p0006Preferred embodiments of the invention are described in the subclaims.

p0007Hereinafter, a preferred embodiment of the invention will be described with reference to the drawing. Show it:<ul><li>Figure 1 - a schematic side view of the upper chair section with the backrest in a forward position,</li><li>Figure 2 - the representation according to Figure 1 with the backrest in a reclined position.</li></ul>

p0008On a seat carrier 1, which is secured to a chair base 2, a backrest support 3 with the backrest 4 in the pivot bearing 5 is mounted pivotally. In the illustrated embodiment, the seat bottom 2 is designed as a chair column.

p0009The chair seat comprises a front 6 and a Stizteil pivotably via a hinge at its rear end associated with the rear seat part eighth

p0010The front seat portion is connected via a bearing 9 with a handlebar 11, which is connected via a bearing 10 to the seat carrier the first In stock 9 which engages an end of an energy accumulator 13, which is connected with its other end on the bearing 13a to the seat carrier. 1

p0011The rear seat part 8 is formed in its basic form as an angle lever and has a lug 8a, which is articulated via a bearing 12 on the seat support 1 or on the upper part of the chair support base. 2 Between the hinge 7 and the bearing 12, a bearing 17 is provided on which an arm 16 is articulated. The handlebar 16 is connected via a bearing 15 having an upwardly projecting portion 14 of the backrest support. 3

p0012The backrest support 3 is formed in the region of the bearing 5 as an angle lever.

p0013During the pivoting of the backrest 4 from the position shown in Figure 1 in a reclined position, the rear seat section is lowered. 8

p0014By locking the energy accumulator 13, which is a gas spring in the illustrated embodiment, the backrest and synchronized so pivoted seat can be locked in any desired pivotal position.
