Abstract: The proposed fastening system for adjustably holding a face-protection shield and/or hearing-protection caps is distinguished by the use of efficiently producible and mountable plastics parts. The carrying straps (110) are latched onto coupling cams, whereby at least two positions--face-protection shield lowered or raised--can be stably set. The holding straps (150) bearing the hearing-protection caps can be clamped and unclamped. The locked adjustment positions are made possible by a combination of a crook (152) located at the end of the holding strap (150) and a counteracting spring bar having a boss profile (149), which combination acts as a switch. If no use of the hearing-protection caps is to be made for some time, the holding straps (150) can be swivelled towards the rear. The system is well protected against dirt contamination, loose parts are avoided and, as a result of the sole use of plastic, the system is also suitable for the electrical field.
