Schalteinrichtung zur Anzeige der Belastung der Sitzfläche eines Kraftfahrzeugsitzes

摘要

A device for indicating a load on a seat such as whether it is occupied by a passenger of a motor vehicle, comprises a seat having an interior spring suspension which flexes downwardly on the load when it is occupied. An indicator pull switch is mounted on a bracket within the interior frame of the seat spring suspension and it includes an actuating member which is engaged by a cable which extends to the spring suspension. The cable is advantageously held under tension produced by a draw spring and it holds the actuating member of the switch in one switch position. When the spring suspension is loaded the tension on the cable is relaxed and the spring actuating member is shifted to another spring position by an internal spring carried by the switch. In another embodiment the cable which is connected to the actuating member is guided through a sleeve guide secured to the spring suspension and its opposite end is looped on an opposite end portion of the seat frame.
