The invention provides a seat-mounted airbag device. A seat-mounted airbag device is provided with: an airbag main body having front and rear chambers that pass from the side of the head of an occupant and deploy toward the front side of a seat by means of gas ejected from an inflator operating on the basis of detection or prediction of a collision of a vehicle, and a tip chamber that opens toward the front side of the seat by means of gas ejected from an inflator operating on the basis of detection or prediction of the collision of the vehicle; and a front-rear chamber that expands inward in the seat width direction from a seat front-side end of the front-rear chamber and that is disposed on a seat front side of a face of the occupant, and that is disposed on a side of a head of the occupant, and that expands inward in the seat width direction from the seat front-side end of the front-rear chamber. During head restraint for restraining the head of the occupant, when a load applied to the airbag body toward the front side of the seat exceeds a predetermined threshold value, the airbag body and the seatback frame are connected by a force restriction mechanism that moves the airbag body toward the front side of the seat.
本公开提供一种座椅搭载型安全气囊装置。座椅搭载型安全气囊装置具备安全气囊主体,所述安全气囊主体具有前后腔室和顶端腔室,其中,所述前后腔室通过从根据检测或预测出车辆的碰撞来进工作的充气装置被喷出的气体而从乘员的头部的侧方通过并向座椅前方侧展开,且被配置在乘员的头部的侧方处,所述顶端腔室从前后腔室的座椅前方侧端部向座椅宽度方向内侧展开,并被配置在乘员的面部的座椅前方侧处。在对乘员的头部进行约束的头部约束时,当被施加在安全气囊主体上的朝向座椅前方侧的载荷超过预定的阈值时,通过使安全气囊主体向座椅前方侧移动的力限制机构,来对安全气囊主体和座椅靠背框架进行连结。
