  "textContent": "There is disclosed an airbag control arrangement for a steering-wheel mounted airbag in a motor vehicle having a steering-wheel mounted function switch, such as horn-switch. The arrangement comprises an airbag control circuit mounted to the steering wheel and including a first acceleration sensor, a second acceleration sensor, and a controller. The airbag control circuit is electrically connected to an auxiliary function circuit (e.g. a horn circuit) incorporating said function switch so as to derive operative electric power from the auxiliary function circuit. The controller is configured to output an actuating signal only in response to the receipt of signals from both acceleration sensors. The airbag control circuit is configured to switch from a sleep mode to an operative mode in dependence on an output signal from the first acceleration sensor; the second acceleration sensor being off and the controller drawing a low sleep-current current in said sleep mode, but both being energised and operable in said operative mode.",
