ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to an open roof construction for a vehicle in accordance with the preamble of the independent claims.
Open roof constructions of this kind are known in various versions thereof. Generally, a closure panel includes a link having a rib extending along a length thereof. A guiding head mates with the rib. The guiding head moves along the rib to open and close the closure panel.
The object of the invention is to provide an open roof construction, which embodies an improved construction of the guide head.
SUMMARY OF THE INVENTION
A broad aspect of the invention provides a guide head operable with guideways of a link that allows remarkably smooth movement of the guide head along guideways of the link. The engagement between guide head and link ribs allows minor misalignments without this leading to an accumulation of shearing forces. Production tolerances can be increased without this leading to undesirable play or endangering the functioning of the mechanism in any other manner. In case of incorrect alignment of the link ribs in the longitudinal direction of the panel, negative play will develop, which will quickly lead to the required running fit as a result of the use of plastic material in one embodiment. Shearing forces are more precisely determined and wear characteristics are improved. The wear-in times are reduced.
