Motion assembly and open roof assembly provided therewith

A motion assembly is provided for moving a number of panels between a coplanar position in which the panels are positioned adjacent each other and extend in the same plane, and a stacked position in which the panels are positioned one on top of the other. Each panel at each of its longitudinal sides is provided with a forward guide pin and a rearward guide pin which are guidingly housed in guides extending in parallel to said longitudinal sides. The guide for the forward guide pin ends in a first inclined guide section enclosing an angle with the remainder of said guide. The guide for the rearward guide pin ends in a second correspondingly inclined guide section enclosing an angle with the remainder of said guide. The distance between the first inclined guide section and the second inclined guide section substantially corresponds with the distance between the forward and rearward guide pins. Connecting devices are provided for connecting each panel with an adjacent panel. The first inclined guide section comprises alternating inclined parts and parts extending in parallel to the guide, wherein the spacing between two successive parallel parts substantially corresponds with the spacing of the panels in the stacking direction.
