Abstract

The invention relates to fall arrester for damping a falling body, which substantially comprises a fall arrester element (3) that is linked with connecting elements (1, 2) via load suspension means (1', 2'). The fall arrester element (3) consists of at least one fiber bundle of a thermoplastic polymer with a stress-elongation behavior that is characterized by a wide elongation range (.epsilon..sub.1, .epsilon..sub.2) in which a substantially continuous force transduction takes place. In a load situation, the fall arrester element (3) is subject to an elongation (.DELTA.L) from the instant when the load builds up to when the falling body comes to a stop. The decisive parameters for designing the fall arrester element (3) are the material used, the elongation behavior thereof and the length and number of fibers from which the material is made. The invention further relates to the use of said fall arrester in safety belts in vehicles, planes, high-speed trains, buses, motor bikes and in mountaineering.
