Claims Analysis
Total Claims: 36
Claim 1
Independent Claim
150 words
An installation for the closing or opening of apertures in vehicles by means of a closure part, which includes guide means for the closure part and actuating means operable to force the closure part with its edge areas against the edge areas of the aperture and to move the closure part away from the aperture, characterized in that the closure part includes chamber means disposed between said closure part and a support means and consisting of several individual vacuum cells having a volume substantially smaller than the volume between the closure part and the support means wherein the volume of the chamber means is a variable volume connected with a vacuum source, spring means being provided for urging the closure part and the support means away from one another, wherein the chamber means create forces acting in the expansion or contraction direction between said closure part and said support means.
Claim 2
