1. A knee protection equipment for a person kneeling on a ground comprising:

  • a left means for resting on the ground configured to be positioned at a level corresponding to the left tibia of the person, comprising a left element (50) configured to cover the left tibia of the person;

    a right means for resting on the ground configured to be positioned at a level corresponding with the right tibia of the person, comprising a right element (50

    ) configured to cover the right tibia of the person;

    a harness (3) configured to be positioned at a level corresponding with the pelvis of the person so that the person can sit in the harness,said harness (3) and said left element (50) is connected by a first left rigid arm (4) configured to be positioned laterally and externally to the left thigh of the person, wherein;

    said first left rigid arm (4) is connected to said harness (3) at a first proximal end by a first connection,said first left element (50) is connected to said first left rigid arm (4) at a distal end by a first articulation (6) via a second left rigid arm (5) secured to the left element (50), said first articulation (6) joining and articulating said first left rigid arm (4) and said second left rigid arm (5),said harness (3) and said right element (50

    ) is connected by a first right rigid arm (4

    ) configured to be positioned laterally and externally to the right thigh of the person, wherein;

    said first right rigid arm (4

    ) is connected to said harness (3) at a second proximal end by a second connection,said first right element (50

    ) is connected to said first right rigid arm (4

    ) at a distal end by a first articulation (6

    ) via a second right rigid arm (5

    ) secured to the right element (50

    ), said first articulation (6

    ) joining and articulating said first right rigid arm (4

    ) and said second right rigid arm (5

    ),the knee protection equipment being able to pass from a standing position by the person in which the left means for resting on the ground and the right means for resting on the ground are positioned at a level corresponding with the tibia of the person, to a kneeling position by the person in which the left means for resting on the ground and the right means for resting on the ground bear on the ground and are able to transmit at least part of a vertical load force applied by the person to the harness, and wherein;

    said first articulation (6) and said second articulation (6

    ) each have a stop that limits a bending motion to a locked position, in the kneeling position by the person, said first left element (50) and said first right element (50

    ) each bears on the ground and each is able to transmit the load force applied by the person to the harness,said first articulation (6) is configured to lock after bending by a first angle as measured between said first left rigid arm (4) and said second left rigid arm (5) of less than 90°

    , andsaid second articulation (6

    ) is configured to lock after bending by a second angle as measured between said first right rigid arm (4

    ) and said second right rigid arm (5

    ) of less than 90°

    to enable the person to maintain a seated position while resting on the harness (3).
