The invention discloses a vehicle safety airbag door hinge, which comprises a fabric layer, wherein the fabric layer comprises an extensible part, the extensible part comprises first areas and secondareas based on the direction perpendicular to the extension direction of the extensible part, the first areas and the second areas are arranged alternately, and each first area comprises meshes arranged at intervals. According to the vehicle safety airbag door hinge provided by the invention, the extensible part has higher ductility so as to prevent a safety airbag door from being separated from abearing member; and due to the arrangement of the multiple meshes, the extensible part can be structurally deformed to further increase the ductility of the extensible part, so that the tensile forceborne by the extensible part in the opening process of the safety airbag door can be reduced, and the risk that the fabric layer is broken due to the fact that the fabric layer is subjected to too large shearing tensile force is avoided.
本发明公开了一种车辆安全气囊门铰链,车辆安全气囊门铰链包括:织物层,所述织物层包括可延展部分,基于与所述可延展部分的延展方向垂直的方向,所述可延展部分包括交替排列的第一区域和第二区域,各个所述第一区域包括间隔设置的网孔。根据本发明的车辆安全气囊门铰链,其中可延展部分具有较高的延展性,以防止安全气囊门与承载部件分离。同时由于多个网孔的设置,使得可延展部分可以发生结构变形,进一步增加了可延展部分的延展性,可以降低可延展部分在安全气囊门打开过程中受到的拉力,避免织物层受剪切拉力过大而造成断裂的风险。
