A method for varying the spring rigidity of an elastomer engine mount for motor vehicles, having two rubber bodies being at least intermittently connected in series, includes intermittently spanning one of the two series-connected rubber bodies as a function of predetermined operating parameters with rigid components of the mount by means of a separate force brought to bear from the outside. Induced forces are elastically effectively received with only the other of the two rubber bodies. An elastic engine mount, especially for motor vehicles, includes rotationally symmetrical rubber bodies disposed one above the other in series. The first rubber body is fixed between an engine mount plate and a support plate. The second rubber body is fixed between the support plate and a retaining plate to be pivoted at a vehicle body. An annular housing surrounds and partly encompasses the second rubber body. One end surface of the housing is rigidly connected to one of the plates bounding the second rubber body and the other end surface of the housing encompasses the rim of another of the plates with play. A spreading device operates between the one plate and the other plate for bringing those plates plate into contact with the housing and spanning the second rubber body.

A method for producing and vulcanizing an inflatable hollow body from a double cloth having upper and lower plies with edges and pile yarns spacing the plies apart includes applying a respective gas-tight unvulcanized layer of rubber to each of the upper and lower piles of the double cloth. The edges of the upper and lower plies are joined with angle braces forming a hollow body. The hollow body is evacuated over a predetermined period of time and the hollow body is vulcanized in the evacuated state.
