Definitions
- the invention relates to a backrest, in particular for an office chair, according to the preamble of the first claim.
- Backrests especially for chairs used in the office or commercial area in addition to ergonomic, aesthetic and economic aspects Take into account. From an ergonomic point of view, alongside a kinematic coupling the seat of the chair in particular also the back-shaped and flexible Storage of the backrest a role.
- European Patent EP 0 308 538 in this regard, a movably mounted backrest is specified, which is designed such that supporting both sagittal and torsional and transverse movements of the back gives way.
- This backrest comprises a fixed cushion shell into which a cushion is inserted is.
- the so-called membrane technology is also common. With this technique, a reference to a frame is stretched.
- the invention therefore achieves the object of specifying a backrest in membrane technology, which is easy and inexpensive to manufacture, which is also aesthetic and ergonomic Fully meets requirements and has a long service life.
- This The object is solved by the features of the first claim.
- the essence of the invention is therefore that the frame of the backrest is articulated and open at the bottom.
- the frame is thus rotatable to a certain extent. Therefore, the frame can be easily done refer to the cover.
- the frame can then be inserted by inserting a crossbar be brought into the final form. This will stretch the cover in the transverse direction. By pulling the cover in the longitudinal direction towards the crossbar, a three-dimensional is created Formation of the backrest surface, that in sagittal or vertical and horizontal Level meets ergonomic requirements.
- the frame faces the one opposite the crossbar Corners joints on.
- the joints can be angled to run to withdraw the reference.
- Another preferred exemplary embodiment is characterized in that that the crossbar is equipped with a groove in which a sewn-in profile of the Reference can be inserted. This represents an extremely simple way of attaching the cover on the crossbar and enables a defined tension of the cover in Longitudinal fastening without protruding fringes or annoying stitches. Further Embodiments result from the corresponding dependent claims.
- the frame 1 shows a frame 1 according to the invention and an insertable crossbar 2.
- the frame 1 is open at the bottom and consists essentially of bent tubes. He is therefore very easy to manufacture.
- the tubes are open at the bottom and for receiving appropriate Prepared pin 3 of the crossbar 2.
- the frame has 1 joints 4 at corners.
- the frame points depending on the one you want Backrest shape, for example, essentially the shape of a square "U” on die Leg 5 of the "U” can be pivoted with the help of the joints 4 relative to the cross connection 6 become.
- the frame 1 takes its final shape only by inserting the crossbar 2 a. In order to fix this position, there are 5 fastening tabs 7 on the legs provided with a correspondingly shaped mounting plate 8 of the crossbar screwed or mechanically connected in some other way.
- FIGS. 3 to 7 different stations are shown when covering the frame 1 with a cover 9.
- the cover 9 is bag-shaped and can either be sewn or otherwise Joining at least two parts or by weaving a one-piece Sacks are formed.
- the shape of the cover 9 is essentially due to the design of the chair and given by ergonomic requirements.
- the cover 9 is in this position in the longitudinal and transverse directions not yet excited.
- the tension in the transverse direction is achieved in that, as in Figure 5 is shown, the legs 5 are pressed apart until the crossbar 2 in the provided openings of the frame 1 can be inserted ( Figure 6). Subsequently the cover 9 is stretched against the crossbar to build up a longitudinal tension (FIG 7).
- the cover 9 has at its opening Sewn-in profiles 10, which are inserted into a groove 11 provided in the crossbar 2 can be (piping technique).
- Figure 8 shows this process in detail.
- the profiles 10 are in arranged on both sides of the sewn-in tunnel 12.
- Figure 9 shows the frame 1 from the side. It can clearly be seen how the joints 4 are angled slightly are and the frame 1 forms a light, stepped arc. After stringing of the frame 1 with a cover, is formed in relation to the transverse and longitudinal tension a three-dimensional shape, that of an ergonomically favorable, back-supporting Area corresponds. For the user, the backrest according to the invention is made of this Reason very comfortable. The ergonomic support is particularly noteworthy thanks to the three-dimensional shape of the reference surface and the good ventilation of the backrest. If desired, an additional cushion can be attached to the cover.
- the backrest according to the invention is summarized by a simple and cost-effective production and excellent ergonomic and aesthetic properties out.
