| 摘要 |
The invention relates to a device (100) including a first fixing member (103), which includes a first fixing surface (105), an additional fixing element (104), which includes an additional fixing surface (106), and a folded flat composite (101), which is at least partially fixed between the first fixing surface and the additional fixing surface. The folded flat composite (101) includes a first composite region (107) and an additional composite region (108). The first composite region (107) includes a first layer sequence, including, from the additional fixing surface to the first fixing surface, a first composite layer (201), a second composite layer (202), a third composite layer (203) and a fourth composite layer (204). The additional composite region (108) includes an additional layer sequence, including, from the additional fixing surface to the first fixing surface, the first composite layer (201), the second composite layer (202) and the fourth composite layer (204). The first composite layer (201) includes a first carrier layer (205), the second composite layer a second carrier layer (208), the third composite layer a third carrier layer (209), and the fourth composite layer a fourth carrier layer (212). In the first composite region (107), the first (205) or the fourth (204) carrier layer or each are characterized by a higher layer thickness than the second (208) or the third (209) carrier layer or each, and in the additional composite region (108), the second carrier layer (208) is characterized by a higher layer thickness than in the first composite region. The additional fixing surface (106) includes a recess (213) and the first composite region (107) and the additional composite region (108) each are located at least partly between the recess (213) and the first fixing surface (105). |
