摘要

The waistbelt has a band, which is placed around the lumbar and a buckle, which is fastened to an end (1) of the band. Another end (3) of the band is fixed in the buckle. The buckle is designed such that the latter end of the band is fixed if the strain of the band relative to the buckle does not exceed a predetermined parameter and the buckle slides the latter end of the band relative to the buckle if the strain exceeds the parameter. The belt is equipped with a unit for regulating the predetermined parameter.
