Positioning devices with tolerance compensation, a set of automotive components comprising such a device and a positioning method with tolerance compensation

A positioning device with tolerance compensation, for positioning a first automotive component with respect to a second automotive component by fastening the first automotive component on an intermediate component, the positioning device with tolerance compensation comprising:

• a screw having at least:
• one driving portion configured to cooperate with a driving tool so as to rotatably drive the screw, the driving portion being located in an axial end portion of the screw,
• one primary external thread and one secondary external thread, the primary external thread being further from the driving portion than the secondary external thread, the direction of the secondary external thread being opposite to the direction of the primary external thread, and
• one abutment extending in protrusion between the primary external thread and the secondary external thread,
• a primary tightening member having a primary internal thread configured to cooperate with the primary external thread, the primary tightening member being intended to be secured to the first automotive component;
• and
• a secondary nut having a secondary internal thread configured to cooperate with the secondary external thread, the secondary nut and the abutment being configured to bear against the intermediate component so as to fasten the first automotive component on the intermediate component, wherein
• the primary external thread, the secondary external thread, the primary internal thread and the secondary internal thread are configured so that a secondary torque caused by the frictions between the secondary external thread and the secondary internal thread is higher than a primary torque induced by the frictions between the primary external thread and the primary internal thread.
