Abstract: The invention relates to a cylinder head gasket comprising a gasket unit (10), which has at least one through opening, particularly a combustion chamber opening (12), and which has at least two interacting gasket plies (18, 20, 22) of which one (18, 20) is provided with a flexible bead (26, 28) encircling the through opening, and the other (22) is provided with a device (34) that limits this flexibility. Said device (24) has, on opposite sides (34, 38), alternating recesses (30) and elevations (32) whereby a recess (30) is located, at least partially, opposite an elevation (32).

Abstract: Cylinder head gasket with a gasket plate formed by at least one layer of sheet metal and at least one combustion chamber aperture which is enclosed by a sealing device serving the purpose of sealing the combustion chamber, wherein in order to reduce any warpages of an engine block and/or of a cylinder head a supporting device is provided radially outside the sealing device on the gasket plate; so that the supporting device can be produced in a material-saving and procedurally reliable manner, the supporting device has an area of the sheet-metal layer which is thickened by way of embossing and does not enclose any of the apertures of the gasket to be sealed completely or almost completely and has at least one embossed supporting bead with a meandering shape or a two-dimensional pattern of cup-like recesses and associated elevations.
