Seat runner with position sensor

A runner for a vehicle seat, the runner extending mainly in a longitudinal direction, and comprising:

• a female profiled section configured to be fixed to a vehicle floor,
• a male profiled section mounted to slide with respect to the female profiled section in the longitudinal direction, an internal runner space being delimited between the male profiled section and the female profiled section, the male profiled section comprising, in the longitudinal direction, a first end, and a second end, and having a web and first and second side walls, the web extending longitudinally substantially in the longitudinal direction and transversely in the transverse direction, said web being continued downwards by the first and second side walls,
• a position sensor, attached to the male profiled section, in the internal runner space, and configured so as to determine the position of the male profiled section with respect to the female profiled section, at least in the longitudinal direction of the runner, the position sensor comprising a sensor body and a sensitive portion extending projecting from the sensor body, the sensitive portion being arranged through a first opening of a first one of the first and second side walls,
• the position sensor further comprising a flexible portion with a fastening portion for fastening the flexible portion to the male profiled section,
• the flexible portion being configured to elastically stress the sensitive portion through the first opening towards the outside in a deployed position of the sensitive portion when the female profiled section is not opposite the first opening, said sensitive portion being configured to come into contact with the female profiled section by causing its retraction toward the internal runner space in a retracted position,
• the fastening portion being configured to fasten in a second opening arranged on a second wall of the first and second side walls, opposite the first wall having the first opening,
• the position sensor being configured to be joined to the runner by longitudinal assembly, during which the position sensor is inserted into the internal runner space via one of the first and second ends of the male profiled section.
