Abstract

In order to provide a cylinder head gasket, comprising at least one beaded gasket sheet, which comprises at least one combustion chamber opening and a bead, which may be vertically deformed and surrounds the combustion chamber opening, and at least one deformation limiting means adjacent to the bead, which can be produced simply and with low material usage and which is flexible with respect to the arrangement and configuration of the deformation limiting means, it is proposed that the deformation limiting means comprises at least one deformation limiting element disposed on a deformation limiting sheet of the cylinder head gasket, said element having at least one reinforcement region, which is located at a distance from the combustion chamber opening and is formed by separating a region of the deformation limiting sheet along a separating line and subsequently bending this region out of the plane of the deformation limiting sheet.
