Claim:
Roll-over protection device for a motor vehicle, said device comprising: a roll bar provided with an at least nearly U-shaped design having a transverse yoke and lateral limbs leaving a loading opening unobstructed and extending to span substantially the width of the vehicle, the lateral limbs being displaceable along fixed guiding devices in order to transfer the roll bar out of a lowered non-operational position into a raised supporting position; a central retaining and activating device for the roll bar, said central retaining and activating device being controlled by an actuator; and a synchronizing device connected to both limbs of the roll bar to synchronize the displacement of the limbs along the guiding devices; wherein the synchronizing device is provided with a synchronization shaft that is mounted fixedly parallelly to the transverse yoke and is connected to each of the limbs by means of a tooth profile that meshes with a notched strip that is arranged on the assigned limb.
