Abstract: The invention relates to a restraint bar for securing a person in vehicles, especially for amusement rides. Said restraint bar is hinged at the top end of a seat and the end of the restraint bar opposite the hinge can be folded up to allow a person to board and get off. The bar can be lowered onto the shoulder and breast side of the person for the purpose of securing the person. The inventive restraint bar is associated with auxiliary bars (2) that are fastened to the restraint bar and that can be introduced with their free ends in a plane below the zone of the restraint bar facing the shoulders, thereby allowing the restraint bar to be used also for smaller persons, especially for children. In a second embodiment, the hinge of the restraint bar can be vertically displaced relative to the seat.
