Description

Airbag device and seat assembly Technical Field The application relates to the technical field of safety airbags, in particular to an air bag device, and particularly relates to a far-end air bag device. The application further relates to a seat assembly provided with said airbag device. Background Along with the continuous improvement of the safety performance requirements of automobiles, the far-end air bags are used as key components for guaranteeing the safety of passengers in automobiles, and are increasingly widely applied to automobile safety systems. The distal airbag is typically located on the side of the main drive seat near the neutral position (depending on the type of rudder car, position difference), and contains two bulky airbag cavities for the abutment head and chest. When the vehicle collides, the far-end air bag can be rapidly inflated to form a soft cushion, so that the impact force on the head and the chest of the passenger is effectively reduced, the collision risk between the passengers in front row is reduced, the contact risk between the passengers and the central control armrests, the seats, the door inner decoration parts and the like is reduced, the possibility of injury of the passengers is greatly reduced, and the safety of the passengers is protected. Currently, the distal end balloon on the market mainly exists in two forms, namely a soft-covered balloon and a hard-shell balloon. As the hard-shell airbag, that is, the distal airbag using a box-shaped hard plastic housing, the components such as the gas generator, the airbag, etc. are integrated into the hard plastic housing to form a module whole. In order to ensure smooth ejection of the air bag during ignition, a tearing line and a closing buckle are required to be designed, but the design makes the structure extremely complex, high failure risk exists, and in the process of ejecting the air bag, fragments are extremely easy to generate and fly out of the hard plastic shell, so that potential threat is formed to the safety of passengers. As the soft package air bag, namely the far-end air bag in the soft package cloth form is adopted, the whole module is wrapped by soft cloth, but the soft package air bag is limited by arrangement factors such as seat foaming requirements (for example, the foaming space is too small), framework design and the like due to the difference of seat designs of different manufacturers, and cannot be adopted in many cases, otherwise, the local collapse of the seat can be caused, and the appearance is seriously influenced. In addition, the soft bag air bag is usually wrapped outside the air bag by adopting non-woven fabrics to fix the bag and prevent dust, however, the design needs to additionally increase a bag type guiding structure on the seat to be used for expanding and guiding the air bag, and under the conditions that the surface of the seat framework for installing the air bag is uneven and the installation space is extremely limited, the convex hull or the concave hull of the seat surface is easily caused on the uneven seat framework, and the requirement of an automobile user on the appearance is difficult to meet. The hard shell air bag is wrapped by the plastic shell, so that a better appearance effect can be achieved after the seat is assembled, a bag type guide structure is not needed, but because the assembly structure is complex, more failure risk points exist at the positions of the buckle, the hinge, the tearing line and the like, and the reliability is difficult to guarantee. In view of the above, the conventional distal airbag has disadvantages in terms of reducing failure risk points, improving safety, ensuring seat appearance, reducing manufacturing costs, and/or improving assembly efficiency. Disclosure of utility model It is therefore an object of the present application to provide an airbag device which overcomes at least one of the drawbacks of the prior art, whereby it is possible to provide targeted advantages in terms of reduced risk of failure, improved safety, ensured seat appearance, reduced manufacturing costs, and/or improved assembly efficiency. Furthermore, the application provides a seat assembly equipped with the airbag device. According to a first aspect of the present application there is provided an airbag device comprising a housing body comprising a first housing portion and a second housing portion which transitions into the first housing portion at an angle to the first housing portion, wherein a four-sided open housing structure is defined by the first housing portion and the second housing portion and a receiving space is defined by the four-sided open housing structure, and an airbag module comprising an airbag and a gas generator, the airbag module being arranged within the receiving space and being secured to the housing body via fastening means. According to the application, through the shell structure with four open sides, the design of the tearing
