The control unit 2 may be an air-bag control unit (ACU) or an electronic control unit (ECU) integrated with the ACU.

An air inflator 1 is provided with an inflator (not shown) for generating gas by receiving a control command from the control unit 2 when the vehicle collides, and an air cushion (not shown) is inflated by receiving gas from the inflator. Will be protected.

In addition, the control unit 2 is connected to the airbag 1 through the wiring 3 to transmit a control command to the airbag 1, the wiring 3 is connected to the collision detection sensor, passenger detection sensor, pretensioner, etc. A plurality of connectors 4, 5, 6 are arranged.

The airbag system of the vehicle according to the present invention configured as described above, when a vehicle collision occurs, transmits a collision detection signal from the collision detection sensor to the control unit (2), and whether the passenger is seated in the passenger seat from the passenger detection sensor and By transmitting to the control unit 2 whether the seated passenger is a child or an adult, the control unit 2 operates the air bag 1 and the pretensioner when the deployment condition of the air bag 1 is satisfied.

The plurality of connectors 4, 5, 6 comprise a control unit 2, an air bag 1, a number corresponding to the number of peripheral devices such as the collision detection sensor, the passenger detection sensor and the pretensioner. Hereinafter, the plurality of connectors 4, 5, 6 include a control unit connector 4 for connecting the control unit 2 and the wiring 3, and an airbag connector for connecting the airbag 1 and the wiring 3 ( 6) and a peripheral device connector 5 disposed between the control connector 4 and the airbag connector 6 and connected to any one of the collision detection sensor, the passenger detection sensor, and the pretensioner, the wiring 3 Only three will be arranged in the following description.

On the other hand, the vehicle is provided with an airbag warning lamp (not shown) indicating whether the wiring 3 is interrupted by the plurality of connectors 4, 5, 6, so that any one of the plurality of connectors 4, 5, 6 is provided. When is disconnected, the airbag warning lamp is turned on to inform the user that the airbag system needs maintenance.

In addition, when any one of the plurality of connectors 4, 5, 6 is disconnected from the plurality of connectors 4, 5, 6, different resistance signals are transmitted to the control unit 2, Through the airbag warning lamp, resistance signal means 10 for informing the disconnected connector are respectively arranged.

That is, three airbag warning lamps corresponding to the number of the connector are disposed in the vehicle, and the control unit 2 matches the resistance signal among the three airbag warning lamps according to the different resistance signals. Can be turned on. In addition, the user may be informed of the disconnected connector by changing the color of the airbag warning lamp which is lit according to the different resistance signals, without having to arrange three airbag warning lamps.

The plurality of connectors 4, 5, 6 are intermittently interposed with the first connectors 4a, 5a, 6a and the first connectors 4a, 5a, 6a connected to the control unit 2, and the airbag 1 It comprises a second connector (4b, 5b, 6b) to be connected.

A terminal 3a, which is a rear end of the wiring 3, is disposed in the first connectors 4a, 5a, and 6a, and a tip of the wiring 3 that is fitted to the terminal 3a in the second connectors 4b, 5b, and 6b. The in pin 3b is arranged so that the terminal 3a and the pin 3b are connected when the first connector 4a, 5a, 6a and the second connector 4b, 5b, 6b are connected or disconnected. By disconnecting, the wiring 3 is interrupted.
