摘要： The invention provides an improvement to a chair which has a tiltable seat carrier (1) and a tiltable backrest (2) on the backrest carrier (5) which are forcibly coupled to one another, and to an individual adjustment of the tilt of the seat carrier (1) in relation to the backrest carrier (5).The improvement consists in the fact that there is provided on the underside of the seat carrier (1) a bearing block (10) having a slideway contour (14) and a vertical slot (13) in which the flange (9) of a lifting element (7) is mounted vertically movably, and the lifting element (7) has a substantially triangular collar (12) which slides on the substantially rectangular slideway contour (14) when the flange (9) moves vertically. This means that the tilt of the seat carrier (1) can be adjusted to be steeper or flatter by turning the lifting element (7), and the limit positions are completely stable. The possibility of automatic unlocking is ruled out.

摘要： A folding table including a folding steel wire frame and a table top. The wire frame includes four vertical struts and four cross-struts, and the table top has a front edge profile connected thereto. The front edge profile pivotably connects to the upper ends of the vertical struts. The vertical struts each connect on their lower ends to rollers in a horizontally non-pivoting manner. The rollers are also connected to the lower ends of the cross-struts in a horizontally pivoting manner. A first anchor plate is arranged on the bottom of the table top for fixably connecting upper ends of two of the cross struts, and a second anchor plate is arranged on the bottom of the table of fixably connecting upper ends of the other two of the four cross struts.
