Definitions
- the present invention relates to a driver airbag device housed in a steering wheel of a vehicle.
- one or more airbag devices are installed in a vehicle to protect occupants in the event of a vehicle accident.
- the airbag device include a so-called driver airbag device that deploys from near the center of the steering wheel to protect the driver, and a driver airbag device that deploys downward inside the window to cause lateral impact, rollover, or overturning of the vehicle.
- a curtain airbag device that sometimes protects the occupant
- a side airbag device that is deployed on the side of the occupant (the side of the seat) to protect the occupant in the event of a lateral impact of the vehicle.
- the driver airbag device housed in the steering wheel it is required to reliably restrain the occupant by promptly deploying the airbag cushion.
- Some airbag cushions used in driver airbag devices are formed by sewing the outer edges of two substantially circular (elliptical) panels together. With such a panel configuration, the structure of the airbag cushion is simplified, and the manufacturing cost can be reduced.
- the expanded and expanded airbag cushion has a shape close to a sphere due to the dispersion of the internal pressure. For this reason, the head of the occupant (driver) comes into contact with the curved airbag cushion, and the head rotates, making it difficult to properly protect the occupant (head).
- an airbag cushion having a conical trapezoidal shape in an expanded and deployed state is adopted by the occupant side panel, the steering side panel, and the side panel connecting these panels.
- the occupant facing surface can have a shape close to a flat surface.
- the internal pressure of the airbag cushion increases, the occupant-side panel actually bends, and the head of the occupant in contact with the airbag tends to rotate, so that the restraint cannot be sufficiently improved.
- the present invention has been made in view of the above circumstances, and an object of the present invention is to provide an airbag device having excellent occupant head restraint performance.
- the present invention is an airbag device mounted on the steering wheel of a vehicle, the gas generator fixed to the steering wheel and generating an expansion gas; and the occupant side by the expansion gas. It is equipped with an airbag cushion that expands and expands toward.
