Vehicle seat with monitoring system

A seat comprising:

• a backrest;
• a seating portion connected to the backrest;
• and
• at least one measurement area defined on the backrest and/or on the seating portion, the at least one measurement area comprising at least one interdigital capacitive sensor capable of measuring a distance or a movement of a user occupying the seat,
• wherein the seat comprises four measurement areas, the first and second of the measurement areas being formed on the backrest and one to each side of a horizontal central plane of the backrest, the third and fourth of the measurement areas being formed on the seating portion and one to each side of a transverse central plane of the seating portion and wherein:
• the first measurement area comprises, on each side of a vertical central plane of the backrest, an interdigital capacitive sensor and a resistive electrode;
• the second measurement area comprises an interdigital capacitive sensor and a resistive electrode which are located substantially along the vertical central plane;
• the third measurement area comprises an interdigital capacitive sensor and a resistive electrode which are located substantially along a longitudinal central plane of the seating portion;
• and
• the fourth measurement area comprises, on each side of the longitudinal central plane, an interdigital capacitive sensor and a resistive electrode.
