The apparatus comprises a plate with a flat recess and an insert which is removably mountable in the flat recess of the plate and is configured to receive an information medium which is viewable when the insert is mounted in the flat recess of the plate. For releasably fixing of the insert on mounting of the same in the flat recess, the insert has the following: at least one tongue on a first border area of the insert for engagement in at least one correspondingly shaped groove in the plate, and at least one releasable fixing that is present in or on at least one second border area of the insert and that is operable by twisting and/or sliding at least one component. ## Claims ### Claim 1 Apparatus, in particular for attaching to the back of a seat, said apparatus comprising: a plate with a flat recess; an insert which is removably mountable in said flat recess of said plate and is configured to receive an information medium which is viewable when said insert is mounted in said flat recess of said plate, wherein for releasably attaching of said insert on mounting of the same in said flat recess, said insert has the following: at least one tongue on a first border area of said insert for engagement in at least one correspondingly shaped groove in said plate, and at least one releasable attachment that is present in or on at least one second border area of said insert and that is operable by at least one of twisting and sliding at least one component. ### Claim 2 (depends on 1) Apparatus according to claim 1, wherein said releasable attachment comprises as rotatable component a screw which interacts with a thread provided in said plate. ### Claim 3 (depends on 2) Apparatus according to claim 2, wherein said screw is held rotatably in said insert so that it cannot fall out of or be removed from said insert even on removal of said insert from said flat recess of said plate. ### Claim 4 (depends on 1) Apparatus according to claim 1, wherein said releasable attachment comprises a lock which interacts with said plate. ### Claim 5 (depends on 1) Apparatus according to claim 1, wherein said releasable attachment has as component at least one bolt which can be brought into engagement with said plate by at least one of twisting and sliding. ### Claim 6 (depends on 1) Apparatus according to claim 1, wherein said at least one of twisting and sliding of said at least one component of said releasable attachment is only performable with a tool. ### Claim 7 (depends on 6) Apparatus according to claim 6, wherein said tool is a special tool which is not available to unauthorised persons. ### Claim 8 (depends on 1) Apparatus according to claim 1, wherein said insert has two opposing parallel edges, wherein said first border area lies on a first one of the two opposing parallel edges and said second border area lies on a second one of the two opposing parallel edges. ### Claim 9 (depends on 8) Apparatus according to claim 8, wherein said second border area has two releasable attachments which are provided on opposing ends of said second border area. ### Claim 10 (depends on 1) Apparatus according to claim 1, wherein on mounting in said flat recess of said plate, said insert terminates flush with said plate at least at its border. ### Claim 11 (depends on 1) Apparatus according to claim 1, wherein said insert has a pocket for receiving said information medium, wherein said pocket has an opening for at least one of insertion and removal of said information medium, wherein said opening faces said first border area and wherein said at least one tongue is formed on said first border area such that in at least one position of said apparatus, it can protect said opening from at least one of penetrating objects and liquids. ### Claim 12 (depends on 11) Apparatus according to claim 11, wherein said insert is formed as a rectangular frame, on an upper edge of which said at least one tongue is formed such that it is spaced from a front of said rectangular frame, wherein said pocket is formed on a back of said rectangular frame and has an elongated opening which is oriented towards said upper edge of said rectangular frame and is shorter than said at least one tongue. ### Claim 13 (depends on 11) Apparatus according to claim 11, wherein said apparatus is formed as a folding table attached to the back of a seat, and wherein said at least one position in which said at least one tongue can protect said opening from at least one of penetrating objects and liquids is a rest position of said folding table, in which said folding table is folded against the back of said seat. ### Claim 14 (depends on 1) Apparatus according to claim 1, wherein impact-absorbing material is installed in said flat recess of said plate at least in one border area, which material comes into contact with said insert on mounting of said insert in said flat recess of said plate. ### Claim 15 (depends on 1) Apparatus according to claim 1, wherein said insert furthermore comprises: a frame and a back wall which forms a pocket to receive said information medium, and a transparent sheet or film through which said information medium in said pocket is viewable on mounting of said insert in said flat recess of said plate. ### Claim 16 (depends on 15) Apparatus according to claim 15, wherein said transparent sheet or film is at least partly made of splinter-resistant material. ### Claim 17 (depends on 1) Apparatus according to claim 1, wherein said apparatus is at least partly made of flame-retardant plastic. ### Claim 18 (depends on 1) Apparatus according to claim 1, wherein said information medium is at least one of a printed sheet and an information medium configured to display information, in particular advertising, and said information displayed is changeable by control of said information medium. ### Claim 19 Seat, comprising an apparatus, in particular said apparatus attached to the back of said seat, said apparatus comprising: a plate with a flat recess; an insert which is removably mountable in said flat recess of said plate and is configured to receive an information medium which is viewable when said insert is mounted in said flat recess of said plate, wherein for releasably attaching of said insert on mounting of the same in said flat recess, said insert has the following: at least one tongue on a first border area of said insert for engagement in at least one correspondingly shaped groove in said plate, and at least one releasable attachment that is present in or on at least one second border area of said insert and that is operable by at least one of twisting and sliding at least one component. ### Claim 20 Vehicle, comprising a seat, said seat, comprising an apparatus, in particular said apparatus attached to the back of said seat, said apparatus comprising: a plate with a flat recess; an insert which is removably mountable in said flat recess of said plate and is configured to receive an information medium which is viewable when said insert is mounted in said flat recess of said plate, wherein for releasably attaching of said insert on mounting of the same in said flat recess, said insert has the following: at least one tongue on a first border area of said insert for engagement in at least one correspondingly shaped groove in said plate, and at least one releasable attachment that is present in or on at least one second border area of said insert and that is operable by at least one of twisting and sliding at least one component.
