[0059] It should be noted that these and subsequent other drawings are only examples, and they are not drawn under the condition of equal proportion, and should not be used to limit the actual scope of protection required by the present utility model.

[0060] The terms "first", "second", etc. can be used interchangeably to distinguish one feature from another, and are not intended to indicate that the respective features must be located in the positions shown in the drawings in each embodiment.

[0061] Figure 1 The end face of an unfolded airbag 1 of an automotive airbag (hereinafter simply referred to as airbag 1) is shown. Figure 2 The cross-section of the folded airbag 1 inserted into the protective sleeve 2 is shown. The airbag 1 has an elongated structure. If the Figure 1 airbag 1 in Figure 2 is folded into the state in

[0062] and then the folded airbag 1 is inserted into the protective sleeve 2, during the process of inserting the folded airbag 1 into the protective sleeve 2, the part of the airbag 1 that has not been inserted into the protective sleeve 2 will automatically unfold, causing inconvenience. Figures 4 to 6 As shown in Figure 3 , the automotive airbag folding and sleeving tooling includes a rolling disc 3. Further referring to

[0063] As shown in Figures 4 to 6 , the automotive airbag folding and sleeving tooling further includes a groove member 5. The groove member 5 is provided with an airbag groove 6. Further referring to Figure 10 and Figure 11 , the two ends of the airbag groove 6 in the extending direction are respectively provided with a first end opening 7 and a second end opening 8, and a side opening 9 is provided on one side in the extending direction. Further referring to Figure 4 and Figure 6 , the side opening 9 faces the pressing edge 4, and the pressing edge 4 is arranged on the side where the side opening 9 of the airbag groove 6 is located.

[0064] As shown in Figures 4 to 6As shown, the airbag folding and sleeving tooling for vehicle airbags further includes a sleeve 10. Further referring to Figure 7 , the sleeve is respectively provided with an airbag inlet 11 and an airbag outlet 12 at both ends. Further referring to Figure 4 and Figure 6 , the airbag inlet 11 faces the second end opening 8, and the second end opening 8 and the airbag inlet 11 at least partially overlap.

[0065] As Figure 3 , Figure 4 and Figure 6 shown, the unfolded airbag 1 enters the airbag groove 6 from the first end opening 7. The side opening 9 enables the crimping edge 4 of the rolling disc 3 to contact the side of the airbag 1. The crimping edge 4 squeezes the side of the airbag 1 to fold the airbag 1 inward. As the airbag 1 is continuously fed in, the rolling disc 3 is pushed by the side of the airbag 1 to rotate, so that the crimping edge 4 continuously rolls and squeezes the side of the airbag 1. And the partially folded airbag 1 exits the airbag groove 6 from the second end opening 8, enters the sleeve 10 from the airbag inlet 11. The sleeve 10 blocks the outward expansion of the partially folded airbag 1. As the airbag 1 is continuously fed in, the folded airbag 1 in the sleeve 10 exits the sleeve 10 from the airbag outlet 12, and enters the protective sleeve 2 sleeved on the outer peripheral side of the sleeve 10. The folded airbag 1 is sleeved by the protective sleeve 2.

[0066] Figures 4 to 6 There are two groove members 5 in Figure 10 . The two groove members 5 do not act simultaneously, but are two different embodiments. As Figure 11 shown, in one embodiment, the cross-section of the airbag groove 6 perpendicular to the extending direction can be a right-angled shape. The right-angled airbag groove 6 conforms to the inward folding trend of the airbag 1, facilitating the inward folding of the airbag 1. As

[0067] shown, in another embodiment, the cross-section of the airbag groove 6 perpendicular to the extending direction can be an arc shape. The arc-shaped airbag groove 6 fits the contour of the airbag 1. When the airbag 1 is folded inward, the support for the airbag 1 is uniform and sufficient, facilitating the inward folding of the airbag 1. Figure 3 As

[0068] shown, the crimping edge 4 can have an arc-shaped outer peripheral wall 13. The arc-shaped outer peripheral wall 13 conforms to the inward folding contour of the airbag 1, avoiding the sharp edges from damaging the airbag 1 when squeezing the airbag 1. Figures 4 to 6 As

[0069] shown, the airbag groove 6 can extend along a straight line, the sleeve 10 can extend along a straight line, the extending direction of the sleeve 10 can be parallel to the extending direction of the airbag groove 6, and the airbag inlet 11 is aligned with the second end opening 8. This enables the airbag 1 to be fed into the airbag groove 6 and the sleeve 10 along a straight line during folding and sleeving, which is simple and convenient, and the airbag 1 smoothly enters the sleeve 10 from the airbag groove 6. Figures 4 to 6As shown, the rolling disc 3 can be configured with a planar linkage mechanism 14. The planar linkage mechanism 14 includes an input rod 15 and an output rod 16. The rolling disc 3 is arranged on the output rod 16 and can rotate relative to the output rod 16. When the input rod 15 is lifted, it drives the output rod 16 away from the side opening 9, and when the input rod 15 is pressed down, it drives the output rod 16 close to the side opening 9. This enables, during the folding and sleeving process, the distance between the rolling disc 3 and the side opening 9 to be adjusted by lifting and pressing down the input rod 15, thereby adjusting the force and depth at which the bead 4 presses the side of the airbag 1. Moreover, the operator can feed the airbag 1 with one hand and operate the input rod 15 with the other hand, completing the folding and sleeving of the airbag 1 alone. The operation is simple and convenient, saving manpower. The planar linkage mechanism 14 further includes a sliding sleeve 17. The sliding sleeve 17 is sleeved on the outer peripheral side of the output rod 16, enabling the output rod 16 to translate when moving away from and approaching the side opening 9, preventing the output rod 16 from rotating and causing a change in the position where the rolling disc 3 presses the airbag 1.

[0070] As Figure 4 and Figure 6 shown, the planar linkage mechanism 14 may further include an intermediate rod 18 and a seat plate 19. The input rod 15 is rotatably connected to the seat plate 19 at its root and is provided with a handle 20 at its head for the operator to hold. Taking Figure 4 the direction as a reference, the left end of the intermediate rod 18 is rotatably connected to the middle part of the input rod 15, the right end of the intermediate rod 18 is rotatably connected to the left end of the output rod 16, the rolling disc 3 is arranged at the right end of the output rod 16, and the sliding sleeve 17 enables the output rod 16 to translate left and right when moving away from and approaching the side opening 9.

[0071] As Figures 4 to 6 shown, the airbag folding and sleeving tooling for vehicle safety airbags may further include a base 21. Further combined with Figure 12, a top chute 22 extending along a straight line is provided on the top surface of the base 21, and the extending direction of the top chute 22 is perpendicular to the extending directions of the airbag groove 6 and the sleeve 10. The groove member 5 is arranged on the top surface of the base 21 and is detachably connected to the top chute 22 through a threaded fastener. When folding and sleeving the airbag 1, the threaded fastener is threadedly connected to the top chute 22 to press the groove member 5 against the top surface of the base 21, so as to prevent the movement of the groove member 5. When preparing to fold and sleeve the airbag 1, by loosening or removing the threaded fastener, the position of the groove member 5 can be freely adjusted so that the second end opening 8 of the airbag groove 6 is aligned with the airbag inlet 11 of the sleeve 10. The rolling disc 3 is arranged on a top slider 23 that is slidably engaged with the top chute 22. The top slider 23 is arranged on the top surface of the base 21 and is detachably connected to the top chute 22 through a threaded fastener. When folding and sleeving the airbag 1, the threaded fastener is threadedly connected to the top chute 22 to press the top slider 23 against the top surface of the base 21, so as to prevent unnecessary translation of the rolling disc 3. When preparing to fold and sleeve the airbag 1, by loosening or removing the threaded fastener, the position of the top slider 23 can be adjusted to adjust the distance between the rolling disc 3 and the side opening 9, thereby adjusting the force and depth of the pressing edge 4 pressing the side of the airbag 1. Further combined with Figure 8 , the top slider 23 can be provided with a protruding bottom slide bar 24 on the bottom surface, and the bottom slide bar 24 is inserted into the top chute 22 to limit the sliding of the top slider 23 along the top chute 22.

[0072] As Figures 4 to 6 shown, the translation directions of the output rod 16 when moving away from and approaching the side opening 9 can be parallel to the extending direction of the top chute 22, and thus perpendicular to the extending directions of the airbag groove 6 and the sleeve 10. This enables the output rod 16 to drive the rolling disc 3 to vertically press the side of the airbag 1, facilitating the inward folding of the airbag 1. The planar link mechanism 14 can be arranged on the top surface of the top slider 23 and is detachably connected to the top slider 23 through a threaded fastener. The aforementioned seat plate 19 can be detachably fixed on the top surface of the top slider 23, and the rolling disc 3 is thus installed on the top slider 23. A cushion plate 25 can be arranged between the top surface of the top slider 23 and the bottom surface of the seat plate 19 to adjust the height position of the rolling disc 3, and thus adjust the height position of the pressing edge 4 pressing the side of the airbag 1.

[0073] As Figure 5 and Figure 6As shown, side chute 26 can be provided on the side of base 21. The extending direction of side chute 26 is parallel to that of top chute 22. Sleeve 10 is provided with side slider 27 which is slidably engaged with side chute 26. Side slider 27 is arranged on the side of base 21 and is detachably connected to side chute 26 by a threaded fastener. When folding and sleeving airbag 1, the threaded fastener is threadedly connected to side chute 26 to press side slider 27 against the side of base 21, so as to prevent side slider 27 from moving. When preparing to fold and sleeve airbag 1, by loosening or removing the threaded fastener, the position of side slider 27 can be adjusted, and thus the position of sleeve 10 can be adjusted. Further combined with Figure 9 , side slider 27 can be provided with protruding side slide bar 28 on the side. Side slide bar 28 is inserted into side chute 26 to limit side slider 27 from sliding along side chute 26. Sleeve 10 can be detachably connected to side slider 27 by a threaded fastener at the end where airbag inlet 11 is provided.

[0074] As Figures 4 to 6 and Figure 12 shown, mounting holes penetrating up and down can be provided in top chute 22 of base 21. Base 21 can be horizontally fixed by threaded fasteners, so that the folding and sleeving tooling for automotive airbag can be horizontally arranged, which is convenient for the operator to fold and sleeve airbag 1. Base 21 can be made of aluminum profile.

[0075] Although the present utility model is disclosed as above with embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make possible changes and modifications without departing from the spirit and scope of the present utility model.
