PROBLEM TO BE SOLVED: To provide a furniture product for seating where a frame is arranged in the back area of a seating surface, supports a pelvis supporting part which tilts to the plane surface of the seating surface at a working position, supports a thrust bearing by extending the support element of a supporting frame to the area of a back pad part, is supported by the thrust bearing with a method which can move and operate pivotally, and is connected with a seat frame by a joint in the posterior end part of the seat frame. SOLUTION: A furniture product for seating 1 which is especially related to a working chair is connected with a frame 7 which can operate pivotally for a seat frame 5 and a support frame 2 kinematically. On the one hand, this frame 7 supports a back pad part 8. On the other hand, it also supports a pelvis supporting part 9 which is arranged in the back area of a seating surface 6. In a working position, in order to operate the pelvis supporting part 9 so that it tilts upward to the plane surface of the seating surface 6, a thrust bearing 13 for the frame 7 or the back pad part 8 is arranged in a support element 11. On the one hand, the frame 7 is supported by this thrust bearing 13. On the other hand, in the posterior end part of the seat frame 5, the frame 7 is connected with the seat frame 5 by a joint 14 designed as a hinge joint. Therefore, when the back pad part 8 is tilted from the working position to a rest position, thereby the back pad part 8 tilts and falls at the same time. Furthermore, the pelvis supporting part 9 which is tightly connected with the back pad part 8 also falls. This moves forward. COPYRIGHT: (C)2011,JPO&INPIT
