Abstract
Abstract A fixed folding top for a passenger car extends from a windshield frame to a rear lid and can be swivelled around a stationery swivelling axis extending transversely to the longitudinal direction of the vehicle from a closed position into an open position and vice versa. A cupola-shaped end area of the folding top that in driving direction extends essentially behind a side door, extends with its lower edge to the rear lid. In order to improve the stiffness of the folding top, a plate-shaped element is arranged adjacent to the lower edge of the cupola-shaped end area and is aligned approximately horizontally and, at least with one end that is located in the rear in the driving direction, is connected firmly with the folding top to form an exterior cover in the open position of the top.

Claim 1
Independent Claim
211 words
A rotatable top for a passenger car having a front and a rear spaced along a longitudinal axis of the car as well as a front windshield frame, at least one side door and a rear lid, the rotatable top comprising: a roof member rotatably movable between open and closed positions about a swivelling axis extending transversely to the longitudinal axis of the car, the roof member extending between the front windshield frame and the rear lid, in the closed position, with a dome-shaped end area of the roof member positioned behind the side door, said end area having a lower edge, adjacent the rear lid; a substantially horizontal plate-spaced element positioned adjacent the lower edge of the dome-shaped end area of the roof member with at least a rear edge connected to the roof member, the plate-shaped element extending substantially over the entire width of the dome-shaped end area of the roof member; an upper peripheral surface of the plate-shaped element forming an interior storage surface when the roof member is in the closed position; and a peripheral surface of the plate-spaced element located on an outside of the vehicle when the roof member is in the open position forming an exterior cover located in front of the rear lid.

A rotatable top for a passenger car having a front and a rear spaced along a longitudinal axis of the car as well as a front windshield frame, at least one side door and a rear lid, the rotatable top comprising: a roof member rotatably movable between open and closed positions about a swivelling axis extending transversely to the longitudinal axis of the car, the roof member extending between the front windshield frame and the rear lid, in the closed position, with a dome-shaped end area of the roof member positioned behind the side door, said end area having a lower edge, adjacent the rear lid; a substantially horizontal plate-spaced element positioned adjacent the lower edge of the dome-shaped end area of the roof member with at least a rear edge connected to the roof member, the plate-shaped element extending substantially over the entire width of the dome-shaped end area of the roof member; an upper peripheral surface of the plate-shaped element forming an interior storage surface when the roof member is in the closed position; and a peripheral surface of the plate-spaced element located on an outside of the vehicle when the roof member is in the open position forming an exterior cover located in front of the rear lid.
Claim 3
Dependent Claim
32 words
A rotatable top according to claim 1, wherein the swivelling axis extends inside the plate-shaped element, said swivelling axis being arranged approximately in a substantially horizontal center plane of the plate-shaped element.
Claim 4
Dependent Claim
60 words
A rotatable top according to claim 1, wherein the passenger car has at least one storage compartment, the plate-shaped member projects at least forwardly from the closed position of the roof member, and the peripheral surface located on the outside when the roof member is in the open position forms an exterior cover for the at least one storage compartment.
Claim 5
Dependent Claim
21 words
A rotatable top according to claim 1, wherein the plate-shaped element is formed integrally in one piece with the roof member.
Claim 6
Dependent Claim
