Abstract

A safety belt arrangement is provided that has a belt retractor that includes a force-limiting device. When triggered in a collision, the belt retractor is associated with limited belt release therefrom. Associated with the belt retractor is a tensioning device that is actuated subsequent to the primary collision and that eliminates slack in a belt that occurs when the force-limiting device is triggered during the primary collision.
