Claim 0:
1. A safety belt, in particular to be installed on an aircraft seat, comprising:
a closing buckle comprising a male element and a female element,
a first strap connected to the male element and a second strap connected to the female element,
the first strap and the second strap being adapted to be fastened together by means of the closing buckle which can pass from an open state to a closed state by causing the male element and the female element to cooperate with one another, wherein said safety belt further comprises:
a system for detecting the closing state of the safety belt and generating a bit of information relating to a closing state of the safety belt, and
a system for detecting a mechanical tension state of the safety belt and generating a bit of information relating to the mechanical tension state of at least one strap of the safety belt,
the system for detecting the closing state comprising:
a magnetic element arranged on one of the elements among the female element and the male element of the closing buckle, and
a magnetic field sensor placed on the other of the elements among the female element and the male element of the closing buckle,
the magnetic sensor of the system for detecting the closing state of the safety belt and the system for detecting the mechanical tension state of the safety belt being arranged on the same male or female element of the safety belt,
the system for detecting the mechanical tension state comprising an elastic member and a switch arranged between a portion of a strap buckle and a portion of a male element or a female element in such a way that, when a mechanical tension applied to a strap exceeds a threshold, the strap deforms the elastic member and activates the switch to indicate that the safety belt is sufficiently tight around a portion of a passenger's body.
