Abstract
Abstract A lifting/sliding roof for vehicles having a cover for the selective closing and at least partial exposing of an opening in the roof. The cover, starting from its closed position, can be swung around a transverse axis located near its front end into a tilted-up position wherein its rear edge is lifted up, and can be, for selected embodiments, slid rearwardly either over or beneath the roof along guide rails, extending on both sides of the opening in the roof, into an open position. A catching device that is automatically adjustable as a function of the motion of the cover can be engaged with a counterbearing in the closed position of the cover for holding down the rear end of the cover. The counterbearing is attached at a stationary part of the roof. The catching device is mounted at the cover so as to be displaceable therewith, but it is also in permanent pivotal engagement with a driving rod member which, during swinging motion of the cover, in a raising as well as in a lowering direction, forces the catching device to carry out an additional movement with respect to the cover which, in the raising direction, assists the upward movement of the rear edge of the cover.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
243 words
A lifting/sliding roof for vehicles having a cover for selectively closing and at least partially exposing an opening in the roof; an operating mechanism serving as a means for enabling a rear end of the cover to be swung in a vertical direction relative to its front end from a closed position into a tilted-up position wherein a rear edge of the cover is lifted up, and for enabling said cover to be slid rearwardly along guide rails from said closed position into an open position; a catching device and a counterbearng, said catching device being automatically adjustable as a function of the motion of the cover and being engageable and disengageable with the counterbearing as a means for holding down the rear end of the cover in the closed position of the cover; wherein the counterbearing is fixedly mounted to a stationary part of the roof, while the adjustable catching device is mounted to the cover so as to be displaceable therewith; and a driving member comprising a rearwardly extending rod structure, wherein the catching device is in permanent relatively displaceable engagement with the rod structure of the driving member which, during the swinging motion of the cover, in a raising direction as well as in a lowering direction, constitutes a means for forcing the catching device to carry out movement with respect to the cover which, in the raising direction, assists the upward movement of the rear edge of the cover.
Claim 2
Dependent Claim
243 words
A lifting/sliding roof for vehicles having a cover for selectively closing and at least partially exposing an opening in the roof; an operating mechanism serving as a means for enabling a rear end of the cover to be swung in a vertical direction relative to its front end from a closed position into a tilted-up position wherein a rear edge of the cover is lifted up, and for enabling said cover to be slid rearwardly along guide rails from said closed position into an open position; a catching device and a counterbearng, said catching device being automatically adjustable as a function of the motion of the cover and being engageable and disengageable with the counterbearing as a means for holding down the rear end of the cover in the closed position of the cover; wherein the counterbearing is fixedly mounted to a stationary part of the roof, while the adjustable catching device is mounted to the cover so as to be displaceable therewith; and a driving member comprising a rearwardly extending rod structure, wherein the catching device is in permanent relatively displaceable engagement with the rod structure of the driving member which, during the swinging motion of the cover, in a raising direction as well as in a lowering direction, constitutes a means for forcing the catching device to carry out movement with respect to the cover which, in the raising direction, assists the upward movement of the rear edge of the cover.
Claim 3
Dependent Claim
46 words
A lifting/sliding roof according to claim 1, wherein the catching device has a catching lever that is coupled to the cover near the rear edge of the cover and said rod structure pivots the catching lever as a function of the swinging movement of the cover.
Claim 4
Dependent Claim
79 words
A lifting/sliding roof according to claim 2, wherein the operating device has a transport carriage which is guided so that it can be slid along a respective guide rail, and wherein the transport carriage is connected with a front part of the cover via a link guide that forces the swinging motion of the cover by means of a limited shifting of the transport carriage in a longitudinal direction of the respective guide rail with respect to the cover.
Claim 5
Dependent Claim
20 words
A lifting/sliding roof according to claim 3, wherein the transport carriages also form a driving member for the catching device.
Claim 6
Dependent Claim
