There is a protective boot (1) made of an elastic material for a piston- cylinder unit with a piston (3) that moves axially in a cylinder bore (2), which has circular end sections (4, 5) that can be fixed to the piston's (3) outer wall on the one hand, and in the cylinder bore (2) on the other, as well as an essentially hollow cylinder-shaped middle section (6) that connects the two end sections (4, 5) to each other and folds radially in the form of a lobe like a rolling bellows when the piston (3) goes in. To ensure that the protective boot (1) folds properl y when the piston (3) goes in, in this invention, the middle section (6) is divided axially into circular longitudinal sections whose lengths are of more or less the length of a fold wall and at least one of the longitudinal sections (7b) has an essentially circular stiffening zone.</SDO AB> |
