2. Folding chair according to claim 1, wherein the seat element comprises a frame with an upper surface defining a plane, wherein at least a portion of the upper surface of the upholstery extends from this plane.

3. Folding chair according to claim 1, wherein the upholstery comprises a front cushion and a rear cushion being divided by the recess.

4. Folding chair according to claim 3, wherein the frame of the seat element comprises a middle cross beam at the location of the recess, wherein the two cushions are supported by the middle cross beam.

5. Folding chair according to claim 4, wherein the frame of the seat element further comprises a first cross beam and a second cross beam, wherein the front cushion is supported by the first cross beam and the middle cross beam and the rear cushion is supported by the second cross beam and the middle cross beam.

6. Folding chair according to claim 4, wherein the middle cross beam has a T-shaped cross section.

7. Folding chair according to claim 1, wherein the end portion of the seat element abuts the rear cross beam when the folding chair is in its use state.

Description

[0013] The invention will now be described in detail by means of preferred embodiments in view of the figures. The figures show:

[0014] FIG. 1A detailed perspective view of a preferred embodiment of the inventive folding chair being in its use state,

[0015] FIG. 2 the folding chair of FIG. 1 being in its storage state, and

[0016] FIG. 3 a sectional view taken along plane A-A in FIG. 2.

[0017] The basic construction of the folding chair being shown in FIGS. 1 to 3 is well known. The folding chair comprises a first front leg 10a and a second front leg 10b extending parallel to the first front leg 10a, a first rear leg 20a whose upper end is connected to the first front leg 10a via a first hinge 12a and a second rear leg 20b whose upper end is connected to the second front leg 10b via a second hinge 12b. So, the rear legs 20a, 20b are connected to the front legs 10a, 10b in a pivoting manner. The rear legs 20a, 20b are connected to one another by a rear cross beam 22 and an additional rear cross beam 23. The two rear cross beams 22, 23 extend substantially perpendicular to the rear legs 20a, 20b. The direction defined by these rear cross beams 22, 23 is referred to as direction D.sub.c of cross beams.

[0018] The front legs 10a, 10b are rigidly connected to one another by means of a backrest 16 and a front cross beam 14.

[0019] A seat element 30 is movable connected to the front legs 10a, 10b and to the rear legs 20a, 20b. In the embodiment shown, a central section of the seat element 30 is connected to the front legs 10a, 10b in a pivoting manner. For this reason, for example a bolt can extend from each front leg 10a, 10b into the seat element 30. One of these two bolts 18a is shown in FIGS. 1 and 2. The end portion EP of the seat element 30 is connected to the rear legs 20a, 20b in a sliding manner. For this reason a groove extends into each rear leg 20a, 20b (shown in FIGS. 2 and 3) and a bolt extends between each groove and the end portion EP of the seat element (these bolts are not shown in the drawings). This is a very common construction, but it is possible to exchange the pivoting and sliding connection, such that the seat element is in sliding connection to the front legs and in pivoting connection to the rear legs.

[0020] The seat element 30 comprises a frame 32 and an upholstery. In the embodiment shown, this upholstery is comprised of two separate cushions, namely a front cushion 38 and a rear cushion 39. The frame 32 consists of two lateral parts 34a, 34b and three cross beams connecting these two lateral parts 34a, 34b, namely a first cross beam 35, a middle cross beam 36 and a second cross beam 37. The rear ends of the lateral parts 34a, 34b form the end portion EP of the frame 32 and thus of the seat element 30. The rear cross beam 22 forms an end stop for this end portion EP when the folding chair is in its use state, as can be seen in FIG. 1.

[0021] As can best be seen in FIG. 3 the cushions 38, 39 are attached to or at least supported by the cross beams 35, 36, 37. For this purpose the cross beams have accommodations for end sections of the cushions 38, 39. The middle cross beam 36 of the frame has a T-shaped cross section and the column of the T separates the two cushions 38, 39.

[0022] Both cushions 38, 39 of course have a seating surface and these seating surfaces extend over the upper surface of the frame 32 at least in sections. This can also best be seen in FIG. 3. Further, the seating surfaces of the cushions are convex meaning that the front cushion 38 has a maximum thickness in a middle portion between the first cross beam 35 and the middle cross beam 36 and the rear cushion 39 has a maximum thickness in a middle portion between the middle cross beam 36 and the second cross beam 37. So, the upholstery being formed of the two cushions 38, 39 has a recess R at the position of the middle cross beam 36 with the surface of the column of the T of the middle cross beam forming the ground of this recess R.

[0023] This recess R in the upholstery is positioned such that when the folding chair is in its storage state (FIGS. 2 and 3) the rear cross beam 22 is located inside this recess R at least in sections. In this state the rear cross beam 22 usually contacts the lateral parts 34a, 34b of the frame. So, despite the fact that the seating surface of the upholstery extends from the surfaces of the frame, the folding chair can be folded like a conventional folding chair without an upholstery, because this upholstery does not interfere with the cross beam 22.
