Abstract
A folding top for a convertible has a lateral folding linkage with linkage legs lying opposite to one another in pairs, symmetrically to the longitudinal center plane of the vehicle. The parallelogram links of the linkage legs form a front and a rear four-bar chain, which is supported in the region of a common connecting leg with at least three hinge points. In the case of the inventive folding top, the connector between the two four-bar chains is constructed as a cantilever girder supporting a rear guiding leg of the front four-bar chain as well as a front main guide bar of the rear four-bar chain with a height distance in in each case one of its hinge points and the front four-bar chain with the front link forming the third hinge point is assigned to this cantilever girder.
Claims13
A convertible apparatus for unfolding and folding a roof material on a frame structure between unfolded and folded positions, comprising a front parallelogramatic linkage (P) adapted to be attached to a front windshield structure and at least partially supporting the roof material, a rear parallelogramatic linkage (R) at least partially supported on said frame structure, said front and rear parallelogramatic linkages (P,R) having a common connecting member (6) having at least first, second and third pivot connections (A,B,C) said first and second pivot connection (A,B) being elevationally spaced from one another, said front parallelogramatic linkage (P) including first and second link members (7,9) pivotably connected to said connecting member (6) at said first and third pivot connections (A,C) respectively, said second link member (9) extending beyond said third pivot connection, said rear parallelogramatic linkage (R) including a third link member (8) pivotably connected to said connecting member (6) at said second pivot connection (B), said apparatus being movable from the unfolded position toward the folded position as said front parallelogramatic linkage (P) pivots about said first and third pivot connections (A,C) in a pivotal direction (F) to thereby effect elevation of said second link member (9) relative to said third pivot connection (C) while said second link member (9) and said third pivot connection (C) are generally lowered relative to said frame structure.
