Abstract: A plate-like component with a fastening device reaching through a fastening opening, the fastening device having: a rigid sleeve reaching through the fastening opening, through which a fastening element can be guided, The sleeve is surrounded at its outer circumference by at least one damping/decoupling body composed of a wire mesh, wherein in the region in which it passes through the fastening opening, the damping body has an outer dimension less than the inner dimension of the fastening opening so that an undersizing is produced and in the region outside where it passes through the fastening opening, at least part of the at least one damping body has an outer dimension in a circumference direction which is of such a size that with a maximum sliding within the undersizing, sufficient overlapping is still assured.

Abstract: A plate-like component with a thickness (t) and with a fastening device reaching through the plate-like component by means of a fastening opening with an inner dimension (D), the fastening device having: a rigid sleeve with a length L>t reaching through the fastening opening, through which a fastening element can be guided, the sleeve is surrounded at its outer circumference by at least one damping/decoupling body composed of a wire mesh, wherein in the region in which it passes through the fastening opening, the damping body has an outer dimension of DDk1<D so that an undersizing U=D?DDk1 is produced and in the region outside where it passes through the fastening opening, at least part of the at least one damping body has an outer dimension of DDk2>D+2*U in a circumference direction.
