The invention relates to a barrier with a barrier bar which can be pivoted electromotively about an axis (16) between two limit positions. The invention proposes to provide in such a barrier a damping element (10) which is operatively connected to the barrier bar. In a particular embodiment according to the invention which is based on a barrier bar which can be pivoted about a horizontally arranged axis (16) between a vertical and a horizontal position, the kinematics between a crank drive (9) which is connected fixed in terms of rotation to the barrier bar and the damping element (10) which is operatively connected thereto are configured such that the damping of the barrier bar takes place as a function of its pivot angle-dependent load moment. <IMAGE>
