System for detecting the presence of a life vest and/or an opening of a life vest compartment

An assembly comprising:

• a life jacket;
• and
• a life jacket compartment delimiting an internal space for receiving the life jacket, said life jacket compartment comprising a first part and a second part, said life jacket compartment being capable of getting into a closed state in which the first part and the second part are pressed against each other and an open state in which the first part and the second part are moved apart from each other in order to allow extraction of the life jacket,
• wherein said assembly further comprises a detection system comprising:
• at least two electrical contacts respectively on the first part and the second part so as to establish an electrical connection between them when the life jacket compartment is in the closed state;
• and
• a detection module able to detect a break in the electrical connection between the electrical contacts,
• the life jacket further comprising an electrical contact arranged to establish an electrical connection with the electrical contacts on the parts, when the life jacket is inside the internal space in the life jacket compartment and the life jacket compartment is in the closed state.
