Abstract
A vehicle airbag device includes an inflator, a bag shaped airbag cushion, and a rectifying member on the inside of the airbag cushion. The rectifying member includes a bottom surface part into which the inflator is inserted, a roof part that, when a rim of a steering wheel is likened to a dial of a clock, extends in a 12 o'clock and 6 o'clock direction on the clock when seen from a driver regularly seated in a driver seat with the steering wheel in a neutral position, and opening parts and formed in the 12 o'clock and 6 o'clock positions. The roof part includes, when seen from a 9 o'clock direction, a top part that protrudes convexly toward a driver side, and ridge line parts and that extend in both the 12 o'clock and 6 o'clock directions of the clock from the top part in an inverted arch shape.
Claims11
A vehicle airbag device installed in a vehicle steering wheel, comprising:
- a stowing part provided further to a center side than a rim of the steering wheel, that opens on a driver side;
- an inflator secured to a bottom of the stowing part;
- a bag-shaped airbag cushion that is stowed in the stowing part with a portion of the inflator stowed therein, that receives gas from the inflator, and expands and deploys toward a driver;
- and
- a rectifying member that is attached to the inside of the airbag cushion, and that covers the inflator, wherein
- the rectifying member includes a bottom surface part installed at the bottom of the stowing part, and has an insertion hole into which the inflator is inserted;
- a roof part positioned on the driver side of the bottom surface part, that, if a virtual disk along the rim of the steering wheel is likened to a clock dial, extends in a direction that connects 12 o'clock and 6 o'clock on the clock, when seen from the driver regularly seated in a driver seat with the steering wheel in a neutral position;
- a side surface part that connects the bottom surface part and the roof part;
- and
- a plurality of opening parts formed in locations corresponding to the 12 o'clock and 6 o'clock positions, respectively, on the clock on the side surface part, and the roof part includes, when seen from a 3 o'clock or 9 o'clock direction of the clock, a top part and ridge line parts formed by stitching triangular edges of the roof part together such that, when the vehicle airbag device is deployed, the top part protrudes convexly toward the driver side, and the ridge line parts extend in both the 12 o'clock and the 6 o'clock directions of the clock from the top part in concave curves toward the inflator to form inverted arch shapes.
