The invention relates to a safety device for stairway elevator systems (10) used for transporting apparatus and goods, especially wheelchairs (9) with persons who are unable to walk. The device is characterized in that the stairway elevator (10) or wheelchair (9) is fitted with a mounting device (20) equipped with a rotation pin (21). A support bracket (30) is mounted on the rotation pin (21) and a braking and blocking device (40) is attached to both the support bracket (30) and mounting device (20). A sensor (70) controls the braking and blocking device (40) in such a way that it blocks the support bracket (30) as soon as the stairway elevator (10) is at risk of tipping over and down the stairs (1) and releases the support bracket (30) when the stairway elevator (10) is placed at a correct angle to the stairs (1).

L'invention concerne un dispositif de sécurité utilisé avec des systèmes monte-escalier (10) pour le transport d'appareils et de marchandises, notamment de fauteuils roulants (9) avec personnes ne pouvant se déplacer, caractérisé en ce qu'il est prévu sur le système monte-escalier (10) ou sur le fauteuil roulant (9), un dispositif de montage (20) équipé d'un axe de rotation (21), en ce qu'un bras support (30) est monté sur l'axe de rotation (21), un dispositif de freinage et d'arrêt (40) est fixé, d'une part sur le bras support (30) et, d'autre part, sur le dispositif de montage (20), et en ce qu'un détecteur (70) commande le dispositif de freinage et d'arrêt (40) de façon qu'il bloque le bras support (30), dès que le système monte-escalier (10) au-dessus de l'escalier (1) menace de basculer et qu'il libère le bras support (30) lorsque ledit système monte-escalier (10) est incliné correctement par rapport à l'escalier (1).
