A driver's seat airbag apparatus for vehicles, comprising:
- a driver airbag which is deployed and expanded from a hub region towards a driver's seat via an inner peripheral side of a rim of a steering wheel surrounding the hub region, wherein:
- the driver airbag is configured so as to comprise:
- a back panel which is attached and fixed to an inflator provided in the hub region, and a bag body which is provided so as to be bonded to the back panel and deployed and expanded from the back panel towards the driver's seat, and
- an attachment center of the inflator to the back panel is set with respect to a center of the back panel so that the attachment center is closer to a bottom of the rim of the steering wheel than to a top of the rim of the steering wheel,
- wherein an upper surface of the driver airbag abuts the inner peripheral side of the top of the rim and a bottom surface of the driver airbag does not abut the inner peripheral side of the bottom of the rim.
A driver's seat airbag apparatus for vehicles, comprising:
- a driver airbag which is deployed and expanded from a hub region towards a driver's seat via an inner peripheral side of a rim of a steering wheel surrounding the hub region, wherein:
- the driver airbag is configured so as to comprise:
- a back panel which is attached and fixed to an inflator provided in the hub region, and a bag body which is provided so as to be bonded to the back panel and deployed and expanded from the back panel towards the driver's seat,
- an attachment center of the inflator to the back panel is set with respect to a center of the back panel so that the attachment center is closer to a bottom of the rim of the steering wheel than to a top of the rim of the steering wheel,
- the center of the back panel is set on a center line of the deployed and expanded bag body which extends in a deployment and expansion direction, and
- a center line on the inner peripheral side of the rim of the steering wheel passes between the center of the back panel and the attachment center of the inflator,
- wherein an upper surface of the driver airbag abuts the inner peripheral side of the top of the rim and a bottom surface of the driver airbag does not abut the inner peripheral side of the bottom of the rim.
