The main bag 112 and the support bag 114 each have a bag shape and are reduced in size and stored in the housing 120 in a stored form 130 such that the support bag 114 is placed on the main bag 112 on the side of the opening 132.
Claims18
An airbag device configured to restrain an occupant of a front seat in a vehicle from a front side of the vehicle, comprising:
- a housing having an opening openable at a prescribed surface and provided in a prescribed location in a vicinity of the front seat;
- a main bag stored in the housing and inflated and deployed from the opening toward a front side of the front seat;
- and
- a support bag provided more inside in a vehicle-widthwise direction than the main bag and stored in the housing together with the main bag to be inflated and deployed from the opening toward a rear side of a center console,
- wherein the main bag and the support bag each are reduced in size and stored in the housing in a stored form as the main bag and the support bag are formed into respective separated masses,
- wherein the support bag is positioned closer to an opening side than the main bag for deploying the support bag before the main bag when the airbag is deployed, and
- wherein a coupling portion between the main bag and the support bag is configured to deploy before the main bag when the airbag is deployed.
An airbag device configured to restrain an occupant of a front seat in a vehicle from a front side of the vehicle, comprising:
- a housing having an opening openable at a prescribed surface and provided in a prescribed location in a vicinity of the front seat;
- a main bag stored in the housing and inflated and deployed from the opening toward a front side of the front seat;
- a support bag provided more inside in a vehicle-widthwise direction than the main bag and stored in the housing together with the main bag to be inflated and deployed from the opening toward a rear side of a center console;
- and
- a coupling portion formed between the main bag and the support bag,
- wherein the main bag and the support bag each are stored in the housing as respective separated masses, and the support bag is reduced in size and stored in the housing beside the main bag on an inner side in the vehicle-widthwise direction, and
- wherein the support bag with the coupling portion is deployed earlier than the main bag when the airbag is deployed because the support bag has a smaller capacity than the main bag.

- a main bag stored in the housing and inflated and deployed from the opening toward a front side of the front seat;
- and
- a support bag provided more inside in a vehicle-widthwise direction than the main bag and stored in the housing together with the main bag to be inflated and deployed from the opening toward a rear side of a center console,
- wherein the support bag protrudes beyond the main bag in a rearward direction in the vehicle when the airbag is deployed,
- wherein the main bag and the support bag each are reduced in size and stored in the housing in a stored form such that the support bag is placed on the main bag on an opening side, and
- wherein a coupling portion between the main bag and the support bag is configured to deploy before the main bag when the airbag is deployed.
