Abstract
Abstract In a motor vehicle body, a rigidly fastened roof (10) of composite material rests upon a frame rigid with the body as a complete prefabricated component. The roof (10) is formed as a composite component which is produced in a hot pressing process and is formed by an air-tight and rain-proof outer layer (11), an intermediate structural layer (12) and a semi-rigid, porous inner layer (13) with a padding and/or decorative layer (14). The continuous edge around the roof is shaped by hot pressing deformation of all the layers to form joining flange areas of different cross-sections which are joined to the areas of the frame rigid with the body by a permanently resilient, vibration-absorbing adhesive bead and by additional screw connections at strategic points.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
113 words
A roof for a motor vehicle body in the form of a layered composite component which is produced in a hot pressing process and comprising an impermeable outer layer, an intermediate structural layer, a semi-rigid, porous layer positioned inwardly adjacent and supportively engaging the intermediate layer and a padding and/or decorative inner layer inwardly adjacent the semi-rigid layer, the continuous edge area of the roof being shaped by hot pressing deformation of all the layers to form joining flange areas of different cross-sections adapted to be jointed to areas of the frame rigid with the body by a permanently resilient, vibration-absorbing adhesive bead and by screw connections at strategic points proximate the bead.
Claim 2
Dependent Claim
113 words
A roof for a motor vehicle body in the form of a layered composite component which is produced in a hot pressing process and comprising an impermeable outer layer, an intermediate structural layer, a semi-rigid, porous layer positioned inwardly adjacent and supportively engaging the intermediate layer and a padding and/or decorative inner layer inwardly adjacent the semi-rigid layer, the continuous edge area of the roof being shaped by hot pressing deformation of all the layers to form joining flange areas of different cross-sections adapted to be jointed to areas of the frame rigid with the body by a permanently resilient, vibration-absorbing adhesive bead and by screw connections at strategic points proximate the bead.
Claim 3
Dependent Claim
20 words
A roof according to claim 1, wherein the impermeable outer layer consists of a self-colored material having a scratch-proof surface.
Claim 4
Dependent Claim
23 words
A roof according to claim 2, wherein the intermediate structural layer consists of a honeycomb web structure of aluminum, plastics material or cardboard.
Claim 5
Dependent Claim
26 words
A roof according to claim 3, wherein the semi-rigid, porous layer consists of a sound-absorbing fleece layer with an air-flow resistance of 30 to 60 rayl.
Claim 6
Dependent Claim
34 words
A roof according to claim 1, wherein the screw connections have outwardly open threaded bores closeable by a cover and exposeable so that they can be used to secure an article to the vehicle.
