Abstract
Abstract Safety apparatus connectible between a human and an electrically conductive terminal includes an electrical part connectible to the terminal, a first electrical cable having one end adapted for electrical connection to the human, and an electromechanical device interconnecting the opposite end of the cable and the electrical part, such electromechanical device including releasably interconnected plug and socket elements and an elongated flexible connection located between the elements and part, the elements being releasable in response to tension exertion transmitted between the cable and the flexible connection.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
126 words
In safety apparatus connectible between a human and an electrically conductive terminal, the combination comprising (a) an electrical part connectible to said terminal, (b) a first electrical cable having one end adapted for electrical connection to said human, (c) means interconnecting the opposite end of the cable and said part, said means including releasably interconnected plug and socket elements and an elongated flexible connection located between said elements and said part, said elements being releasable in response to tension exertion transmitted between said cable and said flexible connection, (d) and a second electrical cable coiled about said flexible connection and connected between one of said elements and said part to transmit electrical current therebetween, and to be free of tension when the flexible connection is tensioned.
Claim 2
Dependent Claim
126 words
In safety apparatus connectible between a human and an electrically conductive terminal, the combination comprising (a) an electrical part connectible to said terminal, (b) a first electrical cable having one end adapted for electrical connection to said human, (c) means interconnecting the opposite end of the cable and said part, said means including releasably interconnected plug and socket elements and an elongated flexible connection located between said elements and said part, said elements being releasable in response to tension exertion transmitted between said cable and said flexible connection, (d) and a second electrical cable coiled about said flexible connection and connected between one of said elements and said part to transmit electrical current therebetween, and to be free of tension when the flexible connection is tensioned.
