The wire of a pillow of safety or натяжителя a seat belt is authorised to be repaired no more, than in two places (fig. 7.108).
Places where out repairs have been carried, increase electric resistance, and thus can cause failures in system self-diagnostics.
At repair of plaits of wires of the module of a pillow of safety and натяжителя a seat belt blooming connectors should be necessarily set not to admit corrosion.
At repair of cables use only wires of yellow colour.
Not to wind the repaired place with a standard insulating tape, it should be designated, having wound with a yellow insulating tape.

Together with a designation yellow изоляционной a tape it provides the easy review of the spent repair work.
Wires to пиропатронам (safety pillows) in a batch production have скрутку with step of 20 mm 5. Such step скрутки is designated in a batch production by numbers of standard details for pairs of wires, therefore at repair follows necessarily observe a step of twisted wires.

Fig. 7.110. A step скрутки


At wire repair to пиропатронам (safety pillows) should be identical length. At twisting of wires 1 and 2 the step скрутки A=20 mm (fig. 7.110) should be by all means sustained.
Thus the wire piece, for example, in the field of welded contacts more long B=100 mm without twisting of wires should not be formed.
