A safety device for an automobile vehicle includes a first integration circuit for integrating an output value generated from a G sensor and a decision circuit for comparing the integrated value with a predetermined decision level to determine whether the safety device should be activated. In the first integration circuit, a previously integrated value is incrementally reduced to provide a current integrated value.

Safety device for an automobile vehicle

An electric connecting device which is arranged midway of a signal line which issues signals to a plurality of electrical appliances. This electric connecting device includes a combination of a plurality of connectors and a connector joining member having a plurality of connector joining parts which are joined electrically to each of the connectors. If at least one of the connectors is not joined normally, the joining of the remaining connectors is regulated by a regulating device which prevents the remaining connectors from being joined to the connector joining member. With the device it is possible to call the attention of an operator to any abnormal joining and to effect the joining of each connector accurately. By making one of the signal lines an airbag circuit for actuating an inflator in an airbag device of a vehicle and making the other of the signal lines a signal line for detecting the abnormality of the inflator and a collision sensor and a horn circuit for tooting a horn, these electrical appliances are connected electrically and accurately and the reliability thereof is improved.
