A first fitting and a second fitting are driven by a common drive shaft. Each of the fittings has a first fitting part and a second fitting part that are connected to one another by a gear mechanism so that there can be a rolling movement of the second fitting part on the first fitting part, with an angle defined between the fitting parts being changed by the rolling movement. Each of the fittings has a driver rotatably mounted in its first fitting part and driving an eccentric arranged so that rotation of the driver causes the rolling movement of the second fitting part on the first fitting part, when the driver is driven by the drive shaft. A stopper is mounted on the first fitting for limiting the angle between the fitting parts. The driver of the first fitting is made of a material with a high mechanical strength and the driver of the second fitting is made of a material with a lower mechanical strength.
