[0035] In the related art, in order to ensure the safety of people in the car, the protection area of ​​the side air curtain inside the car is gradually enlarged. When it expands in the car, the side air curtain unfolds and protects the passengers. When the side air curtain unfolds, the interior trim panel body and the pillar cover plate will break. The breakage of the interior trim panel body and the pillar cover plate will cause hard objects to splash and cause harm to the passengers. Therefore, how to optimize the structure of the interior trim panel body to facilitate the popping out of the side air curtain while avoiding the splashing of hard objects has become a problem that needs to be solved urgently in this field.

[0036] Reference below Figure 1-Figure 7 A side curtain airbag assembly for a vehicle according to an embodiment of the present utility model is described.

[0037] According to the utility model, a side air curtain assembly 1 for a vehicle comprises: an interior panel body 11 and a side air curtain, wherein the interior panel body 11 is suitable for being installed on a pillar of a vehicle; the side air curtain is arranged between the interior panel body 11 and the pillar of the vehicle; wherein a weakened portion is formed on the interior panel body 11, and the weakened portion is on one side of the interior panel body 11 in the width direction and extends along the length direction of the pillar.

[0038] Specifically, the interior panel body 11 is arranged on the side of the vehicle pillar facing the vehicle interior to ensure the beauty of the vehicle interior. A side air curtain is arranged between the interior panel body 11 and the pillar. The side air curtain is usually in a folded or compressed state. When the vehicle collides, the side air curtain pops out from the interior panel body 11 to form a protective barrier to protect the passenger's body and head and reduce injuries. A weakened portion is formed on one side of the interior panel body 11 in the width direction and extends along the length direction of the pillar. When the vehicle collides, the weakened portion can be used as a predetermined rupture area, and the side air curtain can pop out from the weakened portion to protect the passenger. By arranging the weakened portion on the interior panel body 11, space is provided for the side air curtain to explode, which is convenient for the side air curtain to pop out, and it is ensured that the interior panel body 11 is only broken in the area limited by the weakened portion, reducing the broken area of ​​the interior panel body 11, avoiding the splashing of hard objects caused by the explosion of the side air curtain and causing damage to the passenger, thereby improving safety.

[0039] According to the utility model, a weakened portion is provided on the interior panel body 11 of the side air curtain assembly 1. When a collision occurs on the side of the vehicle, the side air curtain expands and pops out to open the weakened portion first, thereby reducing the damage range of the interior panel body 11, preventing other hard fragments from flying out, and ensuring the safety of passengers.

[0040] According to some embodiments of the present invention, the weakened portion is configured as a weakened groove 12 that is recessed on the surface of the interior trim panel body 11 on one side facing the pillar.

[0041] Specifically, the weakened portion is constructed as a weakened groove 12 that is recessed toward the pillar. When the vehicle is hit from the side, the weakened groove 12, as a preset rupture point, can guide the interior panel body 11 to deform or rupture preferentially in this area. When the side air curtain is inflated and deployed, the interior panel body 11 will not become an obstacle, thereby ensuring that the side air curtain can be deployed quickly and fully. The recessed design of the weakened groove 12 reduces the contact area between the interior panel body 11 and the side air curtain, and reduces the resistance that needs to be overcome when the side air curtain is deployed, which helps the side air curtain reach a fully deployed state faster and improves the protection effect.

[0042] According to some embodiments of the present invention, the width of the weakened groove 12 gradually decreases in the direction extending into the weakened groove 12 and the width of the bottom wall of the weakened groove 12 is d and satisfies: 0.1 mm≤d≤0.5 mm.

[0043] Specifically, when the vehicle collides from the side, the collision force acts on the interior panel body 11 and is transmitted to the weakened groove 12 area. As the width of the weakened groove 12 gradually decreases in the extension direction, the collision force is quickly concentrated in this area and causes the material to rupture. As the collision force is further transmitted and the side air curtain is inflated, the interior panel body 11 is deformed and ruptured at the weakened groove 12, providing space for the smooth deployment of the side air curtain. The bottom wall width d of the weakened groove 12 is set to meet 0.1mm≤d≤0.5mm, and d can be constructed to be 0.3mm, which reduces the processing difficulty while ensuring the weakening effect and reducing the resistance of the side air curtain to pop up.

[0044] According to some embodiments of the utility model, the side air curtain assembly 1 also includes a snap connector 13, the two ends of which respectively form a first snap connector 131 suitable for cooperating with the interior panel body 11 and a second snap connector 132 cooperating with the pillar; wherein a weakened connecting arm 133 is formed on the snap connector 13 and located between the first snap connector 131 and the second snap connector 132.

[0045] Specifically, the snap connector 13 includes a first snap connector 131 and a second snap connector 132. The first snap connector 131 is suitable for connecting to the interior trim panel, and its connection form can be a snap or a thread. The second snap connector 132 is connected to the pillar. The pillar is connected to the interior trim panel body 11 through the snap connector 13, which ensures the beauty of the interior while preventing the interior trim panel body 11 from falling off during vehicle driving. A matching hole for accommodating the snap connector 13 can be provided on the interior trim panel body 11 to fix the snap connector 13.

[0046] A weakened connecting arm 133 is provided between the first clamping part 131 and the second clamping part 132. When a collision occurs on the side of the vehicle, the side air curtain expands and pops out, and the weakened connecting arm 133 is deformed or broken under the push of the side air curtain, thereby preventing the interior panel body 11 or the pillar from generating sharp fragments or edges during the collision, reducing the potential risk of injury to passengers and improving safety.

[0047] According to some embodiments of the utility model, a first connecting end face is formed on the first clamping member 131, a second connecting end face is formed on the second clamping member 132, the weakened connecting arm 133 is bent, and the two ends of the weakened connecting arm 133 are respectively connected to the first connecting end face and the second connecting end face; wherein, the cross-sectional area of ​​the weakened connecting arm 133 is respectively smaller than the first connecting end face and the second connecting end face.

[0048] Specifically, the first clip 131 is connected to the interior panel body 11 through the first connection end face, the second clip 132 is connected to the vehicle pillar through the second connection end face, and the weakened connection arm 133 is arranged between the first connection end face and the second connection end face. The weakened connection arm 133 is bent, which not only helps to increase the flexibility and deformation capacity of the connection arm, but also disperses the stress concentration generated during the collision to a certain extent, thereby improving the durability and safety of the entire buckle connector 13. The cross-sectional area of ​​the weakened connection arm 133 is smaller than that of the first connection end face and the second connection end face, respectively, so that the weakened connection arm 133 is relatively weak in structure, and is therefore more likely to deform or break when a collision occurs, thereby reducing resistance and facilitating the ejection of the side air curtain.

[0049] According to some embodiments of the present invention, the side curtain airbag assembly 1 further includes: a first covering member 141 , a protection cavity is formed inside the first covering member 141 , and the snap connector 13 is accommodated in the protection cavity.

[0050] Specifically, the first covering component 141 accommodates the snap connector 13 in the protective cavity. When the side air curtain pops out, the weakened connecting arm 133 will be deformed or broken. The first covering component 141 can wrap the fragments to prevent the fragments from splashing to the outside and causing harm to the passengers. The first covering component 141 can be constructed as a non-woven fabric, which is coated on the outer periphery of the snap connector 13. The non-woven fabric has better airtightness and can effectively prevent the fragments from popping out.

[0051] According to some embodiments of the utility model, the side air curtain assembly 1 also includes: a pillar cover plate 15, a first connector 151 is formed on the pillar cover plate 15, and a second connector 111 which is plugged and matched with the first connector 151 is formed on the interior trim panel body 11; wherein the first connector 151 and the second connector 111 are plugged and matched with each other in the expansion direction of the side air curtain.

[0052] Specifically, a first connector 151 is formed on the pillar cover 15, and a second connector 111 that is plugged into and cooperates with the first connector 151 is formed on the interior panel body 11. By providing the first connector 151 and the second connector 111, the pillar cover 15 and the interior panel body 11 will not break when the side air curtain expands and pops out, thereby preventing the pillar cover 15 fragments from popping out and causing harm to the passengers, and can reduce the resistance of the interior panel body 11 to the side air curtain, making it convenient for the side air curtain to pop out in time to protect the passengers, thereby improving safety.

[0053] According to some embodiments of the present invention, at least a portion of the column cover 15 is recessed, and the first connector 151 is constructed as a plug hole penetrating the column cover 15 . The plug hole is adjacent to the recess, and a reinforcing rib 112 is disposed in the recess.

[0054] Specifically, at least part of the column cover plate 15 is designed to be concave, which is conducive to improving the rigidity and anti-deformation ability of the column cover plate 15. The reinforcing ribs 112 are arranged in the concave part to increase the thickness of the concave part to improve the structural strength. The reinforcing ribs 112 are arranged in the concave part of the column cover plate 15, which can significantly improve the anti-deformation ability and bearing capacity of the area, and ensure that the column cover plate 15 is not easily damaged when subjected to external impact.

[0055] The first connector 151 is configured as a plug-in hole, and the second connector 111 can be configured as a limiting rib that cooperates with the plug-in hole. The limiting rib can be configured as a sheet. The limiting rib passes through the plug-in hole to connect the pillar cover 15 with the interior panel body 11 and limit the movement of the pillar cover 15 to prevent the pillar cover 15 from shaking or falling off.

[0056] In some embodiments, reinforcement structures such as blasting reinforcement ribs 153, reinforcement triangular ribs 154, and reinforcement connecting ribs 155 are provided on the depression to improve the structural strength.

[0057] In some embodiments, a plurality of positioning ribs 114 are disposed on the interior trim panel body 11 .
