The invention provides a main driving safety air bag device. A modeling surface of an air bag cover in the main driving safety air bag device is concave inwards or deflects inwards to form an included angle relative to a plane formed by a steering wheel handle ring; the modeling surface of the airbag cover extends to form a three-dimensional space with the edge of the steering wheel ring; the air bag is three-dimensionally sewed into a three-dimensional shape; the unfolding direction of the air bag is not perpendicular to the plane formed by the steering wheel handle ring, the main body part of the air bag and the connecting part of the thickened part are located on the same plane, the air bag is naturally in an unequal-thickness state from top to bottom and from thick to thin after being inflated, and the thickened part of the air bag fills the three-dimensional space. The distance loss caused by an included angle in the unfolding process of the air bag is made up; the main body part and the steering wheel handle ring support each other. The modeling surface of the air bag cover deflects by a certain angle relative to the steering wheel handle ring and is matched with the specific shape of the air bag, so that adjustment and installation of the internal structure of a vehicle are achieved, and good safety protection for a main driver after the air bag is unfolded is achieved.
本申请提供一种主驾驶安全气囊装置,主驾驶安全气囊装置中气囊盖的造型面相对于方向盘把圈形成的平面内凹或向内偏转形成一夹角;气囊盖的造型面延伸与方向盘把圈边缘形成立体空间;气袋立体缝制呈立体状;气袋展开方向与方向盘把圈形成的平面不垂直,气袋的主体部分与加厚部分的连接部分在同一平面,气袋充气后自然形成自上而下、由厚至薄的非等厚状态,气袋的加厚部分填补立体空间,用于弥补气袋展开过程中由于夹角造成的距离损失;主体部分与方向盘把圈相互支撑。通过将气囊盖的造型面相对方向盘把圈偏转一定角度并配合气袋特定型体,不仅实现车辆内部结构的调整安装,而且实现气袋展开后对主驾驶乘员较佳的安全保护。
