Abstract

A device for indicating the loading of a seat, particularly an automobile passenger seat, comprises a seat having a spring suspension with a pull switch mounted on a rigid plate held to the underside of the suspension. The pull switch includes an actuating member which is biased in a first switch position by a resilient element which is secured to a laterally remote part of the spring suspension and it operates on the actuating element to move it to a second switch position when the seat is loaded and the switch is moved with the spring suspension as it is flexed on the load.
