Abstract
A bellows as gangway protection between two movably connected car bodies or a jetway has a roof and two side parts facing one another. At least the two side parts have a multiplicity of folds or corrugations formed of a bendable sheet material. Each fold or corrugation has a narrow and a longitudinal side. Two folds or corrugations abutting one another are joined along their longitudinal sides. At least one fold or corrugation has at least one reinforcing section and at least two normal sections. The reinforcing section has a thickness greater than the normal sections. The reinforcing section has a narrow and a longitudinal side. The longitudinal side primarily extends in the direction of the longitudinal side of the fold or corrugation. An extension of the narrow side of the reinforcing section is a maximum of 75% of an extension of the narrow side of the fold or corrugation.
