Description

Technical Field

[0001] The utility model belongs to the technical field of automotive airbags, and particularly relates to a folding device for automotive airbags. Background Art

[0002] Automotive airbags are a key safety device in modern vehicles. Their main function is to protect the occupants by rapidly inflating gas bags during a vehicle collision, reducing the direct impact between the occupants and hard objects inside the vehicle, thereby reducing the risk of injury. An airbag system usually includes components such as an integrated airbag module, a collision sensor, and a signal harness. When manufacturing automotive airbags, they need to be transported to a folding mechanism for folding. The folding method of automotive airbags includes: placing the airbag on a plane so that the part in contact with the co-pilot forms an upper airbag part and a lower airbag part arranged in an up-and-down stacked manner. Then, through a series of folding and winding folds, the airbag finally forms a compact and effectively deployable state. However, the existing device for transporting automotive airbags to the folding mechanism has poor fixity, resulting in the airbag deviating from the predetermined position, so that the folding process cannot be fully executed. For example, some folding or folding steps are missing, and the airbag fails to form a compact and effectively deployable state. Once this happens, during subsequent use, it will affect the protective effect of the automotive airbag and seriously threaten the lives of passengers. Summary of the Utility Model

[0009] In some embodiments, the third through hole is inclined with respect to the column, and the extrusion column can slide along the inclined direction of the third through hole.

[0010] In some embodiments, the pull rod is slidably arranged inside the second through hole. When the pull rod slides up and down, it drives the connecting rod and the pulling frame to approach or move away from the sliding seat, and further drives the extrusion column to slide along the inclined direction of the third through hole, so that the clamping block buckles or releases the mounting plate.
