Abstract

A guide crank for the cover of an openable motor vehicle roof comprises a crank body connected to the cover and including at least one slotted opening. The opening itself either forms a guideway or is used as the receiver of a guide body which has a guideway. At least one stiffening element is provided for bridging the opening at least in one partial area and joining the material areas of the crank body to one another on either side of the opening. The stiffening element makes the guide crank economical with high stiffness and with low material thickness and narrow crosspieces above and below the opening.
