A device includes a series of force sensors (11, 12, 13) with an electrical resistance that varies with the force exerted thereon by the weight of the seat occupant. Individual sensors (11, 12, 13) are connected in parallel between two electrical leads (A, B), thus forming a network overlying a predetermined responsive surface and arranged into a plurality of networks (10, 20, 30) for detecting as many different weight thresholds as there are networks. The collected signals are used to control an airbag as a function of the weight and/or the position of the seat occupant. |
