A gangway for connecting a first car with a second car and allowing passage of passengers from the first car to the second car, has a first hoop for attaching the gangway to the first car, a second hoop for attaching the gangway to the second car, a third hoop and a fourth hoop, the third and fourth hoops being arranged between the first hoop and the second hoop. A connection element is arranged between the third hoop and the fourth hoop and elastically connects the third hoop to the fourth hoop.

Joined automobiles are disclosed. Two separate joinable automobiles, each with its own control system, powertrain, and interior space, can be joined by means of built-in retractable coupling systems, providing a single joined automobile with a contiguous inner space, two powertrains which can be used singly or together, and two control systems. The coupling systems can be used by putting the automobiles in proximity to each other and engaging them, and/or disengaging them for separate use.

The invention relates to an articulated vehicle, for example a rail vehicle or an articulated bus, formed from a plurality of vehicles or vehicle parts (2, 3) connected to one another in an articulated manner, wherein a passage (10) is arranged between the vehicles or vehicle parts (2, 3), wherein the passage has an inner cladding (12) and an outer cladding (14) laterally spaced apart from the inner cladding, wherein the inner (12) and outer cladding (14) are arranged so as to form the spacing (A) relative to one another on the end walls of two adjacent vehicles or vehicle parts, wherein a sound insulation layer (18) can be applied to the free surface (16) formed by the spacing (A) on the end wall.

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, against external influences, as well as a vehicle, a flight passenger bridge or staircase and a building connection comprising such a crossway element.
