  • Patent number: 4731882
    Abstract: A garment that is connectable to a safety line or the like and which includes at least one band, which is intended to take up the weight of a person wearing the garment. The band is disposed to move substantially freely in channels (a-c) in the garment (1), the channels being oriented such that a tensional force in the band, applied at the connection point (21) between it and the safety line, achieves tightening of the band and thereby the garment round the person.
