A vehicle seat suspension mat (12) comprises suspension springs (14) for supporting a seat cushion (16) and a pressure sensor module (18) arranged on the springs for being applied against a bottom surface of the seat cushion. The pressure sensor module produces an electrical signal responsive to pressure acting on it. The pressure sensor module comprises a base plate (20) and a film-type pressure sensor (22) arranged on the base plate. The pressure sensor includes a pressure-sensitive cell (36). The base plate comprises a frame (26) and an actuator (28) that is linked to the frame in such a way that it is capable of movement relative to the frame. The actuator is arranged against the pressure-sensitive cell of the film-type pressure sensor and comprises a fixation element (48) fixing the base plate to the springs. The fixation element provides a spacing between the base plate and the springs.
