The present invention relates to an occupant protection device in which communication is performed between the occupant jacket and the vehicle so as to transmit and receive a signal for igniting the inflator in response.

  Patent Document 1 and the like are known in which an airbag is inflated by wireless communication of a pulse signal between an occupant jacket provided with an airbag and a vehicle provided with an acceleration sensor. .

International Publication No. 02/19850 Pamphlet

  However, Patent Literature 1 does not disclose what kind of wireless communication is performed between the occupant jacket and the vehicle. Thus, when performing wireless communication between the occupant jacket and the vehicle, a high frequency is desirable in order to increase the communication speed. However, the high frequency is weak against the shield, and the capacity of the battery mounted on the vehicle It is difficult to perform high-power wireless communication by the Radio Law.

  The present invention has been made in view of such circumstances, and provides an occupant protection device that reliably inflates an airbag when necessary by performing reliable wireless communication between a vehicle and an occupant jacket. For the purpose.

In order to achieve the above object, according to a first aspect of the present invention, an airbag device including an airbag and an inflator that deploys the airbag by ignition is provided in an occupant jacket worn by an occupant riding in a vehicle. In the occupant protection device, communication is performed between the occupant jacket and the vehicle so as to transmit and receive a signal for igniting the inflator in response to impact detection by an impact detection sensor provided in the vehicle. And a vehicle-side antenna and a jacket-side antenna for performing wireless communication between the occupant jackets are respectively disposed on the vehicle and the occupant jacket at positions facing each other when the occupant gets on the vehicle , The occupant jacket is a rigid component that faces the back or chest of the occupant. A protector extending comprises an outer fabric covering the outer surface of the protector, the jacket side antenna, and characterized in that covered by the outer cloth with mounted along the upper and lower direction on the outer surface of the protector you.

According to the present invention, when an occupant wearing an occupant jacket provided with an airbag device gets on the vehicle, the vehicle-side antenna and the jacket-side antenna face each other, and a low-output high-frequency signal is used. It makes it possible to perform high-speed and reliable wireless communication may be adapted to reliably expand when the air bag required.

Further , even when the jacket-side antenna is provided on the occupant jacket that follows the movement of the occupant, the position of the antenna can be fixedly maintained, and reliable wireless communication is possible.
