  • Patent number: 11396138
    Abstract: A tension member with at least one loop made from fiber-reinforced plastic, which tension member has a plurality of fibers that run substantially parallel to each other, so that the loop is formed by the plurality of fibers, wherein a first group of fibers is turned over along the loop in a first turning direction, while a second group of fibers is turned over along the loop in a second turning direction, which is opposed to the first turning direction. Some of the turned-over fibers of both groups end in a different distance from the vertex of the loop than others of the turned-over fibers, so that a cross-section of the tension member that results from the respective number of fibers that run approximately parallel to each other outside the turning-over area of the fibers approximately continuously decreases until it reaches the cross-section size of the tension member.
