Embodiments of the present invention

The present invention will be described below with reference to exemplary embodiments, in particular in the form of a backrest folding table for a seat in a

Transportation, described. However, the present invention is not limited to such applications. Fig. 1 shows a perspective view of a seat 10, for example, in a means of transport, such as an aircraft, ship, bus or car, can be mounted. The seat rests on a base 20 which is connected to the floor 22, and has a seat cushion 12 with a

Seat 14 and a backrest 16 with leaning surface 18. On the back of the backrest 16 is a

Rear cover 24 attached to the turn a

Folding table 32 as an exemplary embodiment of

present invention is attached. The folding table 32 is shown in Fig. 1 in its folded-up rest position, in which its back 42 is visible; However, it can also be folded down into a second, substantially horizontal position of use, in which he with the

Rear cover 24 includes an angle of about 70 ° -80 °. In this position of use, for example, the table can carry food and drinks or as

Desk pad serve.

The folding table 32 has in its rear side 42 a flat recess in which an insert 49 is removably storable. Fig. 1 shows the insert 49 in its stored in the recess of the folding table 32 state. The insert in turn carries an information carrier, such as a printed sheet with advertising that can be viewed in the rest position of the folding table 32 by a person behind the seat 10, for example, a person sitting on a seat behind the seat 10. Fig. 2 shows a perspective view of the front side of the insert 49 of the folding table 32 according to Fig. 1. Fig. 3 shows correspondingly the back of the insert 49. The insert 49 comprises a frame 56 having an opening 58, a transparent plate 49a, an information medium 60 (for example, a printed with advertising or other content sheet) and a rear wall 50. The rear wall 50 is fixed from behind the frame, for example by gluing. In this case, the disc 49a is held between the rear wall of the frame 56 and the rear wall 50. The rear wall 50 is shaped such that a compartment 52 (see FIG. 52) for receiving the information medium 60 is formed, that has only a longitudinal opening 51 (see FIG. 5) through which the information medium 60 enters the compartment 52 The rear wall further has an opening 61 and a recess 62 which serve to facilitate the insertion / removal of the information medium 60 into the compartment 52 or out of the compartment 52. Thus results in a particularly simple and

cost-effective construction of the insert 49.

At the upper edge of the frame 56 is over the entire

Edge length formed a tongue 59. The tongue 59 may, for example, be formed integrally (monolithically) with the frame 56. The tongue 59 recedes from the front of the frame 56; for example, it may be flush with the back of the frame 56 as shown in FIGS. 2 and 3.

In the lower edge region of the frame 56, two fixing devices 80 are further introduced into the frame 56, the in the present example as screws 81 are executed. Between the two fixing devices 80 is a

Distance element 92 is provided, which supports the insert 49 against the planar recess and thus additionally stabilized. However, this spacer can also be omitted or replaced by an additional fixing device 80.

Fig. 4 shows a plan view of the bottom 42 (see Fig. 1) of the folding table 32 without the insert 49. The

Folding table 32 has a flat recess 44 for receiving the insert 49. At the edge of the planar recess shock-absorbing material 54 is mounted on three sides, for example, to prevent disturbing vibrations of the insert 49 when receiving in the flat recess 44 of the folding table 32 or reduce. At the edge of the flat recess 44 is in the folding table 32 - in Fig. 4th

shown by dashed lines - a groove 48 is provided, which extends over the entire length of the flat recess 44 and the tongue 59 of the insert 49 can accommodate. In the lower region of the areal recess 44, two threads 83 are provided on the left and on the right, into which one of the screws 81 of the fixing device 80 of the insert 49 can be screwed in order to fix the insert 49 in the areal recess 44.

FIG. 5 is a sectional view in the plane V-V of FIG

Use of FIGS. 2 and 3, when the insert 49 is mounted in the planar recess 44 of the folding table 32 shown in FIG.

Clearly visible on average is the folding table 32, the wall 33 and a filling 35 (for example foamed plastic). In the folding table 32, the flat recess 44 is formed, which receives the insert 49. To fix the insert 49 in the planar recess, the tongue 59 of the insert 49 has been inserted into the groove 48 of the folding table 32, and the screws 81 of the fixing devices 80 have been screwed into the threads 83 in the flat recesses {cf. Fig. 5A, which shows a part of the sectional view VA-VA of the insert of Figs. 2 and 3, in which the fixing device 80th

is shown more clearly). The back wall 50 of the insert 32 is then at least partially pressed against the shock absorbing material 54.

To remove the insert 49 from the flat recess 44 (eg, for the purpose of changing the information medium 60) the screws 81 are screwed, the insert 49 in the lower region in which the screws 81 are fixed, moved away from the flat recess 44 and then the tongue 59 is pulled out of the groove 48 down.

Fig. 5 shows that when receiving the insert 49 in the flat recess 44 of the folding table 32 at least the edge (or frame 56) of the insert 49 surface with the

Completing the table surface of the folding table.

Fig. 5 in combination with Fig. 2 also shows that the tongue 59 is formed on the frame 56 of the insert 49, that the penetration of liquids (or objects such as crumbs or other dirt) into the compartment 52, and thus contamination or destruction of the information medium 60 contained in the compartment 52 can be prevented. This is especially true in the position shown in Fig. 5 the folding table 32, which corresponds to the folded-up rest position. For example, if the folding table 32 is cleaned in this position with a damp cloth, liquids may enter the space indicated at 90 between the upper edge of the insert 49 and the upper edge of the planar recess 44, but from there into the region of the opening 51 of the Faches 52, as an effective

Shielding by the tongue 59 takes place. As can be seen in Figure 2, the liquid may then be dispensed either over the front of the insert 49 or on the left or right sides of the frame 56 over its rounded corners

run down as the tongue 59 over the entire

Edge length including that of the rounded corners

Clockwise rotation is added to the protection provided by the arrangement of the tongue nor the effect of gravity, the liquid also leads away from the insert 49 and its compartment 52.

Fig. 5A shows in detail one of the two fixing devices 80 (as a sectional view in the plane VA-VA of Fig. 3), which are introduced in the lower region of the frame 56 of the insert 49 at opposite ends and exemplified as screws 81. To protect against unauthorized operation of the screws 81, the heads of the screws contain a recess that only with a corresponding

Recess 44 are brought. Between the insert 49 and the areal recess, rings 84 plugged onto the screws 81 can additionally be arranged in order to achieve additional damping and / or rattling / vibrations

to reduce .

By the interaction of the tongue 59 with the groove 48th

on the one hand and the interaction of the fixing device 80 with the folding table 32 on the other hand is a robust and secure fixation of the insert 49 in the flat

Recess 44 of the folding table 32 achieved, which can be easily - but only by authorized personnel - again dissolved, for example, to allow a change of the information medium. There are no or only insignificant mechanical loads on the insert 49 (and in particular not on the tongue 59)

Design and arrangement of the tongue 59 is a shield of the compartment 52 of penetrating foreign bodies.

The present invention is not limited to the configuration of the above-described exemplary embodiment. In alternative embodiments, the fixation device 80 may be manipulated, rather than by rotation, by displacement or by a combination of rotation and displacement of an element. For example, the fixing device 80 may have a latch which, for fixing the insert 49 in the planar recess 44, may be displaced (eg linearly displaced) or pivoted into a groove formed in the folding table 32. This groove may, for example, lie in the lower side wall 46 of the areal recess 44, which corresponds to the upper side wall which contains the groove 48.

In a further alternative embodiment, the

Fixing device 80 may also be designed as a lock, which is to be operated exclusively with a key and causes a locking of the insert relative to the folding table 32.

In a further alternative embodiment tongues are not only provided on the upper edge of the frame 56, but also on its side edges. The folding table 32 then has corresponding grooves into which these tongues can engage. This embodiment additionally complicates the unauthorized removal of the insert 49 from the flat

Fixing devices on other edge regions (for example, also on the left and / or right edge of the frame 56, and / or also at the upper edge region on which the tongue 59 is formed) may be provided.

In a further alternative embodiment, the tongue 59 (or other possibly existing tongues) is not angled away from the frame 56 as shown in Fig. 5, but executed as an extension of the frame, so that they are not arranged in a parallel to the surface of the flat recess Groove (as the groove 48 in Fig. 5) engages, but in a direction perpendicular to the surface of the flat recess groove. This can facilitate the insertion / removal of the insert 49, but an unauthorized removal or
