Definitions
- Another improvement of the new plunger lockable Metal compression spring is after Claim 2 characterized in that the Has circumferential edge of the immersion sleeve gradations, which correspond to the width of the Locking stops trained and in axial Staggered towards each other are so that by a rotational movement the immersion sleeve around their axis other graduated peripheral edge of the immersion sleeve for mounting the locking stops can be used. Accordingly, the user of the seat preferred by him front locking position of the backrest select or set.
- FIG. 1 is a simplified side view the chair holder 5 of an office chair with a trackable backrest support 6 (swiveling about axis 7) and one synchronously thus pivotable seat support 8 shown. So that the synchronous adjustment is executable, the backrest support 6 via the axis 9 with the seat support 8 connected.
- the seat support has at the front end one firmly attached to it Sliding axis 10, which are congruent in two Elongated control cams 11 in the side walls the chair holder 5 is guided.
- the control curves run from the front down to the back rising at the top, so that there is an increasing Displacement of the sliding axis 10 results if the backrest support 6 from its illustrated front backrest position in his (not shown) backrest position is moved.
- the plunger 21 is integral with the Plate 17 and the one shown on the left Crosshead 22 formed. He has one slot-like milling in which the two Rocker arms 23 and 24 of an expanding shear the scissors axis 25 are attached.
- the End pieces 26 and 27 of the spreading scissors run in the position of the Plunger in the immersion sleeve 20 and sit in the shown in Fig. 4 Position of the plunger on the peripheral edge the immersion sleeve 20.
