1. an adjustable-pitch handrail, comprising:

  • Fixed part (2), described fixed part (2) is for being connected to the framework of described vehicle;

    Movable part (3), described movable part (3) is by articulated mounting (10,43) described fixed part (2) is articulated with around pivot center (X), to move between reduction angle position and rise angle position;

    AndSystem, described system is used between described raised position, regulating the degree of dip of described movable part (3) described dipping;

    It is characterized in that, described for regulating the system of degree of dip (α

    ) to comprise;

    At least one flywheel bearing (20), described at least one flywheel bearing (20) is selected from the flywheel bearing of Structure deformation type and the flywheel bearing of cam type, described at least one flywheel bearing (20) and described articulated mounting (10,43) are associated to allow described movable part (3) only rotating around described axis (X) on the rotation direction of described raised position from described dipping;

    AndReleasing device, described releasing device acts on described articulated mounting (10,43) and described movable part (3) can be discharged from described raised position to the described rotation dipped, described articulated mounting comprises the turning cylinder (10) aimed at along described axis (X)Wherein, described flywheel bearing (20) is connected to described fixed part (2) freely to rotate around described pivot center (X) with rotating manner, and wherein, described axle (10) is connected in described movable part (3) and is connected to described flywheel bearing (20) with rotating manner, described releasing device (40,

         41) the first operating position and the second operating position can alternately be presented, at described first operating position, described releasing device prevents described flywheel bearing (20) from rotating around described pivot center (X) relative to described fixed part (2), at described second operating position, described releasing device allows described bearing (20) freely to rotate relative to described fixed part (2),Wherein, described releasing device comprises band tooth ring part (40) and at least one movable ratchet (41), described band tooth ring part (40) is connected in described bearing (20) with one heart, at least one movable ratchet (41) described is connected to described fixed part (2) and keeps being engaged in described toothed portion (40) by springing (32)Wherein, described band tooth ring part (40) is formed on lining (43), utilizes described lining (43) described flywheel bearing (20) to be connected to described fixed part (2) with rotating manner.
