[0034] Embodiments of the present application will be described in detail below with reference to the drawings, in which like reference numerals represent like elements or elements having the same or similar function throughout the drawings. The embodiments described below by way of example are intended to explain the present application, and are not to be understood as limiting the present application.

[0035] Reference will now be made to Figures 1-6 The airbag assembly 20 according to the first embodiment of the present application is described below.

[0036] As shown in Figs. Figure 1 , Figure 3 and Figure 4 The airbag assembly 20 according to the first embodiment of the present application includes an airbag cushion 21 and a gas generator 23. The airbag cushion 21 is arranged to be laid on the cushion framework 10 of a seat 100 of a vehicle. The airbag cushion 21 is provided with a plurality of pull straps 211 arranged at intervals around the periphery of the airbag cushion 21. The pull straps 211 are connected to the cushion framework 10. In the present embodiment, "a plurality of" means two or more, for example, the pull straps 211 can be two, four, five, eight or ten. The gas generator 23 is connected to the airbag cushion 21. The gas generator 23 is configured to inflate the airbag cushion 21 when the airbag assembly 20 is triggered. When a vehicle collides, a controller on the vehicle determines that the collision condition meets the condition for triggering the airbag assembly 20, and the controller sends an instruction to the gas generator 23. The gas generator 23 inflates the airbag cushion 21. The inflated airbag cushion 21 protects the occupant. Thus, the airbag cushion 21 can be deployed. The volume of the airbag cushion 21 increases after inflation. Thus, the airbag cushion 21 can provide cushioning for the occupant's downward movement on the occupant's lower side, thereby reducing the probability of the occupant colliding rigidly with the seat, and thus reducing the probability of the occupant being injured, and improving the safety of the vehicle.

[0037] At the same time, the airbag cushion 21 can provide support for the occupant on the occupant's lower side, lifting the occupant's thighs upward, and providing resistance on the front side of the occupant's thighs and hips. On the one hand, this can reduce the forward displacement of the occupant, and reduce the probability of the occupant colliding rigidly with the front side objects such as the steering wheel or instrument panel. On the other hand, when the occupant is in a lying position, the direction of the force between the airbag cushion 21 and the occupant after the thighs are lifted is at a small angle with the direction of the compression force on the occupant's spine. Thus, the airbag cushion 21 can better absorb the compression force on the occupant's spine. Thus, the probability of the occupant being injured can be further reduced, and the safety of the vehicle can be improved.

[0038] It can be understood that during the use of the vehicle, the long-term sitting of the occupant on the seat and the vibration of the vehicle itself will generate an acting force on the airbag bag 21, and will affect the shape and position of the airbag bag 21 on the seat cushion framework 10. In the embodiment, by arranging a plurality of spaced-apart pull belts 211 around the airbag bag 21, the pull belts 211 are connected to the seat cushion framework 10, and when the airbag bag 21 is subjected to an acting force, the plurality of pull belts 211 can pull the airbag bag 21 at a plurality of positions around the airbag bag 21, thereby preventing the airbag bag 21 from deforming and displacing, so as to reduce the probability of the airbag bag 21 being wrinkled or deviating from the designed position, improve the probability of the airbag bag 21 being deployed in the correct posture at the set position, and further improve the safety of the vehicle.

[0039] According to the airbag assembly 20 of the first aspect of the present application, when the vehicle is in a collision, the inflation of the airbag bag 21 can support and buffer the occupant, thereby improving the safety of the vehicle. By fixing the airbag bag 21 on the seat cushion framework 10 through the plurality of pull belts 211, the probability of the airbag bag 21 being deployed in the correct posture at the set position can be improved, and the safety of the vehicle can be further improved.

[0040] In some embodiments of the present application, as shown in Figure 1 , Figure 3 and Figure 4 , the airbag bag 21 is quadrangular when not filled with gas, and the airbag bag 21 is provided with a plurality of pull belts 211 on the left and right side edges. For example, the left side edge of the airbag bag 21 can be provided with two, three or four pull belts 211, and the right side edge of the airbag bag 21 can be provided with two, three or four pull belts 211. In this way, the plurality of pull belts 211 can pull the airbag bag 21 at a plurality of positions on the left and right side edges of the airbag bag 21, thereby preventing the airbag bag 21 from deforming and deviating, and meeting the need for limiting the airbag bag 21.

[0041] In some embodiments of the present application, as shown in Figure 3 , Figure 4 and Figure 6 , the pull belts 211 are provided in four, including a first pull belt 211a, a second pull belt 211b, a third pull belt 211c and a fourth pull belt 211d, and the first pull belt 211a, the second pull belt 211b, the third pull belt 211c and the fourth pull belt 211d are arranged at intervals on the left and right side edges of the airbag bag 21. Among them, the first pull belt 211a and the second pull belt 211b are symmetrically arranged relative to the longitudinal center line of the automobile seat 100, and the third pull belt 211c and the fourth pull belt 211d are symmetrically arranged relative to the longitudinal center line of the automobile seat 100. In this way, the pull belts on the left and right sides are symmetrically arranged, which can not only better ensure the limiting of the pull belts 211 on the airbag bag 21, prevent the airbag bag 21 from deforming and deviating, but also will not cause the structure to be complex and the cost to rise due to too many pull belts 211.

[0042] In some embodiments of the utility model, as shown in Figure 6 The outer end of the first pull strap 211a and the second pull strap 211b is 32mm-36mm away from the X direction of the seat R point, preferably 34mm; the outer end of the first pull strap 211a and the second pull strap 211b is 206mm-218mm away from the Y direction of the seat R point, preferably 212mm.

[0043] The outer end of the third pull strap 211c and the fourth pull strap 211d is 244mm-250mm away from the X direction of the seat R point, preferably 247mm; the outer end of the third pull strap 211c and the fourth pull strap 211d is 195mm-207mm away from the Y direction of the seat R point, preferably 201mm.

[0044] The angle between the extension direction of the first pull strap 211a and the second pull strap 211b and the Y direction is 26°-34°, preferably 30°.

[0045] The applicant finds that through the design and optimization of the arrangement parameters of the above-mentioned pull strap 211, the pull strap 211 can better limit the airbag bag 21, further prevent the airbag bag 21 from deforming and deviating, and better meet the limiting needs of the airbag bag 21.

[0046] In some embodiments of the utility model, as shown in Figure 4 And Figure 5 The airbag bag 21 includes a first bag body 212 and a second bag body 213, the first bag body 212 is connected to the front side of the second bag body 213, and the airbag bag 21 is configured to have a height greater than that of the second bag body 213 when the airbag assembly 20 is triggered.

[0047] Therefore, when the vehicle collides, on the one hand, the blocking effect of the airbag bag 21 on the occupant in the front-rear direction can be improved, further reducing the forward movement of the occupant when the vehicle collides, and on the other hand, the absorption degree of the compression force of the airbag bag 21 on the occupant's spine can be improved, thereby further reducing the probability of injury to the occupant when the vehicle collides, and improving the safety of the vehicle.

[0048] The inner pull strap 214 is arranged in the airbag bag 21, and the inner pull strap 214 defines a gas passage arranged left and right and extending front and back in the airbag bag 21; when the airbag assembly 20 is triggered, the gas generated by the gas generator 23 gradually fills the airbag bag 21 through the two gas passages, so that the airbag bag 21 can be more evenly unfolded.

[0049] In some embodiments of the utility model, as shown in Figure 5As shown in the first aspect of the present application, the upper side surface of the first bag body 212 is a circular arc column surface that protrudes upward and extends left and right when the airbag assembly 20 is triggered. Thus, the upper side surface of the first bag body 212 is more suitable for the posture of the thighs and calves of the occupant, so that the airbag bag 21 is more ergonomic when it is deployed, and the airbag bag 21 can better absorb the force of the occupant's legs, further reducing the probability of injury to the occupant when the vehicle collides, and improving the safety of the vehicle.

[0050] As shown in the first aspect of the present application, the upper side surface of the second bag body 213 is a plane, or the upper side surface of the second bag body 213 is a circular arc column surface that is concave downward and extends left and right when the airbag assembly 20 is triggered. Thus, the upper side surface of the airbag bag 21 can be more ergonomic, and the airbag bag 21 can better transmit the impact force from the occupant, thereby further reducing the probability of injury to the occupant when the vehicle collides, and improving the safety of the vehicle.

[0051] According to the second aspect of the present application, the automobile seat 100, as shown in Figure 1 , Figure 3 and Figure 4 , comprises a cushion framework 10, a first fastener 22 and the airbag assembly 20 of the first aspect of the present application, the pull belt 211 is formed with a first fixing hole 2111, the cushion framework 10 is formed with a first mounting hole, and the first fastener 22 passes through the first fixing hole 2111 and the first mounting hole to connect the pull belt 211 with the cushion framework 10. Thus, in the process of connecting the pull belt 211 and the cushion framework 10, the operation is relatively simple, and the fastener connection strength and reliability are relatively high, and it is relatively easy to make the connection strength and reliability of the pull belt 211 and the cushion framework 10 meet the use needs. Preferably, the first fastener 22 is a fastening bolt. Of course, in other embodiments, the first fastener 22 can also be other forms of fasteners, such as rivets, as long as it can fix the pull belt 211 to the cushion framework 10.

[0052] In some embodiments of the present application, as shown in Figure 1 and Figure 3 , the cushion framework 10 is formed with a mounting groove 11, and the airbag assembly 20 is arranged in the mounting groove 11. In the process of assembly, the mounting groove 11 can quickly position the airbag assembly 20, thereby improving the assembly speed of the airbag assembly 20, and after assembly, the assembly accuracy of the airbag assembly 20 can be improved. In the process of use of the vehicle, the mounting groove 11 makes the position of the airbag assembly 20 more downward, which can reduce the probability of the occupant contacting the gas generator 23 of the hard material in the airbag assembly 20, and improve the riding experience of the occupant. When the airbag assembly 20 is triggered, the mounting groove 11 can limit the displacement of the airbag bag 21, further improve the probability of the airbag bag 21 being deployed at the set position, and improve the safety of the vehicle.

[0053] AsFigure 3 As shown in the figure, the height of the bottom wall of the mounting groove 11 increases in the direction from back to front. Thus, on the one hand, it is easier to realize that the seat cushion is higher in front and lower in back, so that the posture of the automobile seat 100 is more in line with ergonomics, and the riding experience of the occupant is improved. On the other hand, when the airbag assembly 20 is triggered, the bottom wall of the mounting groove 11 can better block the airbag bag 21 and the occupant, thereby further reducing the forward movement of the occupant during vehicle collision and improving the safety of the vehicle.

[0054] In some embodiments of the present application, as shown in Figure 4 and Figure 5 , the gas generator 23 is connected to the rear side of the airbag bag 21, wherein the height of the rear side of the mounting groove 11 is lower, which can reduce the probability of contact between the gas generator 23 and the occupant, further improve the riding experience of the occupant, and the gas generator 23 can pull the airbag bag 21 from the rear side, further improving the probability of the airbag bag 21 being deployed in the correct posture at the set position.

[0055] In some embodiments of the present application, as shown in Figure 3 , the automobile seat 100 further comprises a protective pad 30 arranged between the airbag bag 21 and the cushion framework 10. By arranging the protective pad 30, the protective pad 30 can provide protection between the airbag bag 21 and the cushion framework 10 during the deployment of the airbag bag 21, reducing the probability of the cushion framework 10 cutting the airbag bag 21, and improving the reliability of the airbag bag 21 during deployment.

[0056] In some embodiments of the present application, as shown in Figure 1 , Figure 2 , Figure 4 and Figure 5 , the gas generator 23 is provided with a second fastener 231, and the cushion framework 10 is further provided with a second mounting hole 13, and the second fastener 231 is fitted into the second mounting hole 13 to connect the gas generator 23 with the seat framework. Thus, during the connection of the gas generator 23 and the cushion framework 10, the operation is simple, and the fastener connection strength and reliability are high, and it is easier to make the connection strength and reliability of the gas generator 23 and the cushion framework 10 meet the use needs. Preferably, the second fastener 231 is a fastening bolt. Of course, in other embodiments, the second fastener 231 can also be other forms of fasteners, such as rivets, as long as it can fix the gas generator 23 to the cushion framework 10.

[0057] In some embodiments of the present application, as shown in Figures 1-3As shown, the rear end of the cushion framework 10 is provided with left and right extending support shafts 12, the support shafts 12 are provided with mounting plates 121, the mounting plates 121 have downwardly folded mounting folded edges 1211, and the second mounting holes 13 are formed on the mounting folded edges 1211. In this way, the damage to the support structure on the cushion framework 10 is less during production, the thickness of the mounting plates 121 is thinner, and the second mounting holes 13 are easier to open, thereby the production difficulty of the automobile seat 100 can be reduced, and the yield of the automobile seat 100 can be improved.

[0058] During product design, the installation needs of different models of the airbag assembly 20 can be met by adjusting the position of the mounting plate 121, the folding angle or size of the mounting folded edge 1211 and other parameters, thereby the product design difficulty can be reduced.

[0059] In some embodiments of the present application, as shown in Figure 1 and Figure 3 As shown, the automobile seat 100 further comprises a backrest framework 40, the backrest framework 40 is rotatably connected with the rear end of the cushion framework 10, and the backrest framework 40 is used for supporting a seat backrest. During product design, the size or shape of the backrest framework 40 and the cushion framework 10 can be adjusted, thereby more product design needs can be met.
