Abstract
Abstract A convertible top for vehicles with a frame and a textile cover, in which two columns stretching the cover material are pivotal about an axis extending transversely to the vehicle and with a closed convertible top have a maximum distance from one another at the height of the upper edges of the side walls of an associated body; this maximum distance is adapted to be automatically reduced in the course of the folding-in operation by means of spring-loaded adjusting mechanisms as a function of the pivot angle of the columns stretching the cover material. In order to enable a folding-in of the convertible top into a top box of a vehicle rear section tapered for aerodynamic reasons, the columns supporting the fabric material of the textile cover are each formed by a roof column and a fabric-retaining bow-shaped member of which the roof column extends offset toward the inside and the fabric-retaining bow-shaped member is arranged on the outside of the roof column, and the fabric-retaining bow-shaped member which is pivotally connected in the upper area of the roof column, is adapted to be pivoted from an outwardly pivoted stretching position in which, with a closed top, it predetermines the lateral inclination of the textile cover, into a pivoted-in folding position in which it extends essentially parallel to the roof column.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
258 words
A convertible top for vehicles of the type having flexible cover means and a frame means for supporting the cover means, the frame means comprising, two column means for stretching the cover means when in a closed convertible top position, said column means being spaced from one another in a transverse direction of a vehicle and being mounted for pivotal movement about a transverse vehicle axis with the column means having a maximum distance from one another with a closed convertible top substantially at the height of upper edges of side walls of an associated vehicle body, column adjusting means for automatically adjusting a maximum width of the convertible top at the column means so that said width is reduced in the course of the convertible top folding-in operation in dependence on a pivot angle of the column means, said column means being each formed by a roof column constituting a main support and by a fabric-retaining bow-shaped member, the roof columns extending offset toward the vehicle inside and the bow-shaped member being arranged on the outside of a respective roof column, the bow-shaped member being pivotally connected to a corresponding roof column in the upper area thereof, and said column adjusting means including further adjusting means for controlling the movement of the bow-shaped member so that it is pivotal from an outwardly deflected stretching position in which it predetermines a lateral inclination of the cover means with a closed top, into a pivoted-in folding position in which it extends at least approximately parallel to the roof column.
Claim 2
Dependent Claim
258 words

Claim 3
Dependent Claim
36 words
A convertible top according to claim 1, wherein the pivot axis of the roof columns is offset toward the rear with respect to the longitudinal alignment of the bow-shaped member when the convertible top is closed.
Claim 4
Dependent Claim
128 words
A convertible top according to claim 2, wherein the further adjusting means includes a knee lever means at each vehicle side, respective first levers of said knee lever means being pivotally connected at the bow-shaped member and respective second levers being pivotally connected at the associated roof column, the knee lever means being automatically transferable during the closing operation of the convertible top approximately into a stretched position with support of the respective knee joints of the knee lever means at a respective fixed abutment, said first levers being respectively spring-loaded by a spring means in such a manner that during the pivoting back of the convertible top the knee lever means are held in a pivoted-in folding position after termination of the support of the knee joint.
Claim 5
Dependent Claim
23 words
A convertible top according to claim 3, wherein the fixed abutment is formed by a box column cover plate of the associated vehicle.
Claim 6
Dependent Claim
15 words
A convertible top according to claim 3, wherein the spring means is a leg spring.
Claim 7
Dependent Claim
76 words
A convertible top according to claim 3, wherein said bow-shaped member is pivotally connected at each vehicle side directly in an upper area of the associated roof column and at an outrigger arm in the lower area of the bow-shaped member by means of two hinge joints, both hinge joints being arranged fixedly with respect to the roof column, and one of the pivotal connections of the knee lever means being constructed as joint bearing means.
Claim 8
Dependent Claim
16 words
A convertible top according to claim 6, wherein the joint bearing means is a ball joint.
Claim 9
Dependent Claim
128 words
A convertible top according to claim 1, wherein the further adjusting means includes a knee lever means at each vehicle side, respective first levers of said knee lever means being pivotally connected at the bow-shaped member and respective second levers being pivotally connected at the associated roof column, the knee lever means being automatically transferable during the closing operation of the convertible top approximately into a stretched position with support of the respective knee joints of the knee lever means at a respective fixed abutment, said first levers being respectively spring-loaded by a spring means in such a manner that during the pivoting back of the convertible top the knee lever means are held in a pivoted-in folding position after termination of the support of the knee joint.
Claim 10
Dependent Claim
15 words
A convertible top according to claim 8, wherein the spring means is a leg spring.
Claim 11
Dependent Claim
71 words
A convertible top according to claim 8, wherein said bow-shaped member is pivotally connected directly in the upper area of the roof column and at an outrigger arm in the lower area of the bow-shaped member by means of two hinge joints, both hinge joints being arranged fixedly with respect to the roof column, and one of the pivotal connections of the knee lever means being constructed as joint bearing means.
Claim 12
Dependent Claim
54 words
A convertible top according to claim 1, wherein said bow-shaped member is pivotally connected directly in the upper area of the roof column and at an outrigger arm in the lower area of the bow-shaped member by means of two hinge joints, both hinge joints being arranged fixedly with respect to the roof column.
Claim 13
Dependent Claim
19 words
The convertible top according to claim 8, wherein the fixed abutment is formed by a box column cover plate.
