Abstract
The invention relates to a convertible top cloth, including an outer top cloth, an inner roof lining, an insulating layer which is arranged between the outer top cloth and the inner roof lining, and at least one absorbent film which is accommodated between the outer top cloth and the inner roof lining, is a plastic film produced at least from polyester and is provided on the insulating layer adjacent to the inner roof lining.
Claims15
A convertible top material comprising:
- an outer top cloth material being substantially watertight and weathering resistant, so to prevent ingress of water from an outside surface of the outer top material,
- an inner roof liner,
- an insulation ply disposed between the outer top material and the inner roof liner,
- wherein the insulation ply comprises a supporting layer and a foam material,
- wherein the insulation ply further comprises at least one sound-absorber film,
- wherein the insulation ply comprises a surface, the sound-absorber film being located on said surface of the insulation ply, said surface of the insulation ply facing one of the outer top cloth material and the inner roof liner,
- wherein the sound-absorber film provides for an acoustical insulation in a direction perpendicular to the surface.
A convertible top cover comprising
- an outer top material,
- a foldable insulation material comprising an insulation ply, the insulation material being disposed adjacent the outer top material, and
- an inner roof liner, the inner roof liner being disposed adjacent the insulation material,
- wherein an air gap is provided between the insulation material and the inner roof liner,
- wherein the insulation material comprises a sound-absorber film having a surface, the sound-absorber film providing for an acoustical insulation in a direction perpendicular to the surface, and
- wherein the insulation material comprises a supporting layer.
An insulation material for use in a convertible top cover comprising:
- a polyurethane foam material,
- a first sound-absorber film, the foam material including a first surface, the first sound-absorber film being attached to said first surface of the foam material, wherein the first sound-absorber film provides for an acoustical insulation in a direction perpendicular to the first surface, and
- a supporting layer arranged on the foam material,
- wherein the insulation material is foldable.
A top cover for use in a convertible vehicle, the top cover being for folding in an opened roof position, the top cover comprising:
- an outer top material having an external surface pointing to the outside of the vehicle and an internal surface;
- an inner roof liner having an internal surface pointing to the inside of the vehicle and an external surface;
- and
- an insulation ply arranged at a distance between the outer top material and the inner roof liner,
- wherein the insulation ply includes at least one externally disposed sound-absorber film for acoustic absorption, and
- wherein the at least one sound-absorber film faces one of said internal surface of the foldable outer top material and said external surface of said foldable inner roof liner,
- wherein the insulation ply is assembled to define a structural unit.
