Abstract: The present invention relates to a roll-over protection device for a motor vehicle, particularly for a convertible, comprising a roll bar (2). This roll bar is provided with an at least nearly U-shaped design having a transverse yoke (3) and lateral limbs (4A, 4B) while leaving a loading opening (11) unobstructed, and extending such that it essentially spans the width of the vehicle. The lateral limbs (4A, 4B) can be displaced along fixed guiding devices (6, 7) in order to transfer the roll bar (2) out of a lowered non-operational position and into a raised supporting position. To this end, a central retaining and activating device (12) for the roll bar (2), said device being controlled by an actuator (18), is provided and/or a device (17) that synchronizes the displacement of the limbs (4A, 4B) of the roll bar (2) along the guiding devices (6, 7) is provided.
