    le dispositif de blocage (8) comportant un élément de blocage (9) qui est couplé en déplacement par l'intermédiaire d'un élément de liaison (14) avec le dispositif de couplage (7) mécanique de telle sorte que par un déplacement en pivotement du dispositif de couplage (7) mécanique, l'élément de blocage (9) soit rotatif autour d'un axe de rotation (10), l'élément de blocage (9) comportant au moins un organe de blocage (18) monté sur celui-ci, par lequel le mouvement en rotation de l'élément de blocage (9) est conçu de manière à bloquer, suite à un dépassement d'une vitesse de déviation fixée de la manette (4),
    l'au moins un organe de blocage (18) étant conçu en forme de levier et par l'une de ses deux extrémités étant logé en étant rotatif en déport radial par rapport à l'axe de rotation (10) de l'élément de blocage (9) dans un point de rotation (19) se déplaçant avec l'élément de blocage (9) entre une position de service normale, libérant un déplacement en rotation de l'élément de blocage (9) et une position de blocage, bloquant un déplacement en rotation de l'élément de blocage (9), et
    un élément à ressort (23) élastique étant prévu, lequel applique sur l'organe de blocage (18) une force le forçant dans la position de service normale, lors du dépassement de la vitesse de déviation fixée de la manette (4), l'au moins un organe de blocage (18) étant conçu pour se déplacer à l'encontre de la force de l'élément à ressort (23) élastique, en s'éloignant en direction radiale de l'axe de rotation (10) et vers un contour de blocage (28), dans sa position de blocage, caractérisé en ce que
    l'élément à ressort (23) élastique est un ressort à branches (24) s'appuyant sur l'élément de blocage (9) et sur l'organe de blocage (18), à la manière d'un ressort basculant qui applique une force forçant l'au moins un organe de blocage (18) soit dans la position de service normale ou dans la position de blocage et qui est placé avec un déport par rapport au point de rotation (19) de l'organe de blocage (18),
    en ce qu'il est prévu un élément de rappel (36) en forme de ressort, lequel applique une force de rappel forçant en retour l'élément de blocage (9) dans une position initiale, dans laquelle la manette (4) n'est pas déviée, la force de rappel de l'élément de rappel (36) étant supérieure à la force de l'élément à ressort (23) élastique, et
    en ce qu'il est prévu un contour de rappel (35), lequel lors du rappel de l'élément de blocage (9) dans sa position initiale, guide l'au moins un organe de blocage (18) de la position de blocage dans la position de service normale.
  2. Agencement de poignée de portière selon la revendication 1, caractérisé en ce qu'une première extrémité longitudinale (13) de l'élément de liaison (14) s'engage sur l'axe de rotation (10) de l'élément de blocage (9) et l'autre deuxième extrémité longitudinale (16) de l'élément de liaison (14) est montée sur le dispositif de couplage (7) mécanique, avec un écart par rapport à l'axe de pivotement (17) de celui-ci.
  3. Agencement de poignée de portière selon la revendication 1, caractérisé en ce que le dispositif de blocage (8) comporte un pot de boîtier (11) fixé sur le support de poignée (6) dans lequel l'élément de blocage (9) est logé de manière rotative, le contour de blocage (28) étant conçu dans la paroi périphérique (29) du pot de boîtier (11), sous la forme d'au moins une protubérance (31) débordant vers l'extérieur en direction radiale et placée à l'extérieur de la trajectoire de l'élément de blocage (9).
  4. Agencement de poignée de portière selon la revendication 3, caractérisé en ce que l'élément de blocage (9) est conçu sous forme de levier avec deux organes de blocage (18) mutuellement opposés en direction radiale.
  5. Agencement de poignée de portière selon l'une quelconque des revendications précédentes, caractérisé en ce qu'un dispositif à câble Bowden actionnant l'agencement de fermeture (5) situé sur le véhicule est en liaison fonctionnelle soit avec l'élément de blocage (9) ou avec le dispositif de couplage (7) mécanique.
  6. Agencement de poignée de portière selon l'une quelconque des revendications précédentes, caractérisé en ce que la vitesse de déviation fixée de la manette (4) est d'au moins 2 m/s.
  7. Agencement de poignée de portière selon l'une quelconque des revendications précédentes, caractérisé en ce que l'axe de rotation (10) est orienté sensiblement à la transversale de l'axe de pivotement (17) du dispositif de couplage (7) mécanique.
