  • Patent number: 11225269
    Abstract: The present invention relates to the use of a multi-layered sheet material (1) comprising a reinforcing member (2), having a polymer coating (3) at least on one side, preferably on both sides, wherein the reinforcing member (2) comprises at least one backing fabric (6) made of warp threads (7a,b) and weft threads (8a,b), and wherein the sheet material (1) comprises at least one channel (12) extending through the sheet material (1), and wherein the warp and weft threads (7a,b; 8a; 8b) are woven together such that the backing fabric (6) comprises both single layer fabric regions (14) and at least one at least two-layered fabric region having at least two fabric layers (15a,b), which are not joined together, so that the channel (12) is each formed between the fabric layers (15a,b), as a bellows wall (19) of a crossway bellows (16), a crossway element comprising such a sheet material for the protection of a passageway of two vehicle parts or components, which are connected together movably relative to each other,
