[0042] like Figure 1-Figure 12 As shown, the seat belt assembly 1 according to the embodiment of the utility model includes: a first seat belt structure 11 and a second seat belt structure 12 .

[0043] The first safety belt structure 11 includes two shoulder safety belts 111, which are suitable for being restrained on both sides of the shoulders of the passenger, that is, the two shoulder safety belts 111 respectively restrain and protect the left and right shoulders of the passenger, preventing the shoulder of the passenger from leaving the seat 13 too far to cause damage to the spine and head and neck, and the left and right shoulder safety belts 111 are symmetrically restrained on both sides of the shoulders of the passenger, so that the passenger can maintain balance and stability during the collision process. Among them, the two shoulder safety belts 111 can be respectively wrapped from the front side of the corresponding shoulder to the armpit, so as to achieve the restraint of the two shoulders, that is, during the collision process of the passenger, the two shoulder safety belts 111 can restrain the passenger from the armpit of the passenger, preventing the passenger from moving forward significantly under the action of inertia, especially for the passenger in the lying state, it has a good restraint effect.

[0044] The second safety belt structure 12 includes a safety belt connector 121 and a lap safety belt 122, two waist safety belts 123 and two front safety belts 124 which are selectively plugged into the safety belt connector 121. The safety belt connector 121 is suitable for being installed on the front side of the abdomen of the occupant, the two waist safety belts 123 are suitable for being restrained on both sides of the waist of the occupant, the two front safety belts 124 are suitable for being restrained on both sides of the front of the occupant, and the lap safety belt 122 is suitable for being restrained between the legs of the occupant on both sides.

[0045] Specifically, the seat belt connector 121 is provided with five plug interfaces, and the five plug interfaces can respectively correspond to the connection with the lap seat belt 122, the two waist seat belts 123 and the two front seat belts 124. The seat belt connector 121 is also provided with buckles, so that the ends of each seat belt can be plugged into the buckles for fixing and tightening, so as to prevent the seat belt from loosening and failing to form tension to restrain the body of the occupant.

[0046] After the passenger gets on the vehicle, the seat belt connector 121 can be taken out and placed on the front side of the abdomen for use. The seat belt connector 121 is located on the front side of the abdomen of the passenger, so that the seat belt connector 121 can be easily connected to each seat belt. Among them, two waist seat belts 123 extend from the bottom of the seat 13, stretch forward obliquely and plug into the seat belt connector 121 to restrain the waist of the passenger, and two front seat belts 124 extend from the rear of the seat 13, extend forward obliquely and plug into the seat belt connector 121 to restrain the shoulders, chest and the entire front of the passenger. The two front safety belts 124 and the two shoulder safety belts 111 form cross restraints on the shoulders of the occupants and reinforce each other, which can further increase the restraint on the shoulders of the occupants and improve the restraint protection on the upper body of the occupants to prevent the occupants from lying back and causing excessive damage to the spine and chest during a vehicle collision. The crotch safety belt 122 can extend upward from the bottom, and the occupants can stretch it upward and plug it into the safety belt connector 121 to restrain and protect the occupants' hips and prevent diving to cause damage to the occupants' spine during a vehicle collision, thereby further improving the protection of the upper body of the passengers.

[0047] It should be noted that when the vehicle is started and the occupant is in a normal sitting position, the occupant needs to plug the two waist safety belts 123 and the two front safety belts 124 into the safety belt connector 121, that is, to form a four-point safety belt to restrain the occupant. When the vehicle detects that the occupant is in a lying position, the crotch safety belt 122 and the two shoulder safety belts 111 pop out, that is, three restraint points are added to form a seven-point safety belt. At this time, the occupant can plug the crotch safety belt 122 into the safety belt connector 121 to restrain the hips, and at the same time, the two shoulder safety belts 111 are tied to both sides of the shoulders to enhance the restraint and protection of the occupant. As a result, the occupants in a lying position can be further restrained and protected by the crotch safety belt 122 and the two shoulder safety belts 111 when the vehicle collides, so that the occupants will not be greatly moved forward due to inertia, and the body can maintain balance and stability, reducing the occupants' spinal and chest injuries by more than 50%, greatly improving the safety of the occupants and reducing the risk of injury.

[0048] The seat belt assembly 1 according to the embodiment of the utility model is provided with a first seat belt structure 11 including two shoulder seat belts 111, and a second seat belt structure 12 including a seat belt connector 121, a crotch seat belt 122, two waist seat belts 123 and two front seat belts 124. Thus, multiple parts of the occupant's body can be restrained and protected, and the restraining effect on the occupant's upper body is enhanced. In particular, it can prevent the spine, chest and cervical vertebrae of the occupant in a lying position from being injured during a collision of the vehicle, thereby effectively protecting the body safety of the occupant.

[0049] In some embodiments, the first safety belt structure 11 further includes a first retractor 112 and two first latching members 113 , and the two shoulder safety belts 111 are respectively distributed in a one-to-one correspondence with the two first latching members 113 .

[0050] Specifically, the first retractor 112 is used to reel in and tighten the two shoulder safety belts 111, and the two latches are used to respectively fix one end of the two shoulder safety belts 111. When the occupant does not need to use the two shoulder safety belts 111, the two shoulder safety belts 111 are both recovered in the first retractor 112. When the occupant needs to use the two shoulder safety belts 111, the two shoulder safety belts 111 can be pulled out of the first retractor 112, and the ends are respectively inserted into the two first latches 113 for fixation.

[0051] Among them, the first retractor 112 and the first latch 113 are both suitable for being installed on the seat back 135, one end of the shoulder safety belt 111 is retracted on the first retractor 112, and the other end is suitable for passing from the top of the corresponding shoulder to the front and extending to the bottom of the shoulder to be plugged into the first latch 113.

[0052] like Figure 6 As shown, the two first latch members 113 are respectively installed on the left and right side surfaces of the seat 13, the first retractor 112 is installed on the reinforcement plate 133 of the seat back 135, one end of the two shoulder safety belts 111 are both retracted in the first retractor 112, and the other end can be pulled out from the first retractor 112. After one of the shoulder belts 111 is pulled out from the first retractor 112, it passes over the shoulder from the top of the left shoulder to the front and extends to the bottom of the shoulder to be inserted into the first latch 113 on the left, that is, it is inserted into the armpit of the left shoulder, and the end of the left shoulder belt 111 is fixed; after the other shoulder belt 111 is pulled out from the first retractor 112, it passes over the shoulder from the top of the right shoulder to the front and extends to the bottom of the shoulder to be inserted into the first latch 113 on the right, that is, it is inserted into the armpit of the right shoulder, and the end of the right shoulder belt 111 is fixed, thereby achieving the tightening of the shoulder belt 111 and the restraint of the occupant's shoulders.

[0053] It should be noted that the first retractor 112 has a self-locking function. After the occupant fastens the seat belt and inserts the shoulder seat belt 111 into the first latch 113 and fixes it, the first retractor 112 automatically tightens it, thereby restraining the shoulders of the occupant on both sides in the two shoulder seat belts 111.

[0054] In some embodiments, the first safety belt structure 11 also includes a first guide member 114, which is installed at a position of the seat back 13 corresponding to the neck of the occupant. The first guide member 114 is provided with two guide holes 115. The two shoulder safety belts 111 are passed from the first retractor 112 to the first guide member 114 and are respectively led out from the two guide holes 115 toward the shoulders on both sides.

[0055] Specifically, Figure 2 , Figure 5 and Figure 6 As shown, the first guide member 114 is located above the first retractor 112 and is installed above the backrest of the seat 13 at a position corresponding to the neck of the occupant. After the shoulder safety belt 111 is pulled out from the first retractor 112, it can pass through the first guide member 114, and the two shoulder safety belts 111 are respectively guided out from the two guide holes 115 toward the shoulders on both sides, and then can be pulled out and extended to the left and right first latches 113 to restrain the entire shoulders of the occupant and ensure the stability of the occupant's body. When the shoulder safety belt 111 is not needed, the shoulder safety belt 111 can be pulled out from the first latch 113, so that the two shoulder safety belts 111 can be automatically retracted into the first retractor 112.

[0056] Therefore, by providing the first guide member 114 to guide the shoulder seat belt 111 , the two front seat belts 124 can be smoothly pulled out or smoothly retracted.

[0057] In some embodiments, the second seat belt structure 12 also includes a second retractor 125, which is used to reel in and tighten the two front seat belts 124. The second retractor 125 is suitable for being installed on the backrest of the seat 13, wherein one end of the two front seat belts 124 are respectively reeled in the second retractor 125, and the other ends of the two front seat belts 124 are suitable for being respectively passed from the shoulders of the occupant on both sides toward the front, around the shoulders and downwardly plugged into the seat belt connector 121.

[0058] Specifically, Figure 2-Figure 3As shown, the second retractor 125 is located above the first retractor 112 to avoid interference between the two. The second retractor 125 is installed on the reinforcing plate 133 of the seat back 13. One end of the two front safety belts 124 are both retracted in the second retractor 125, and the other end can be pulled out from the second retractor 125. After one of the front safety belts 124 is pulled out from the second retractor 125, it passes over the shoulder from above the left shoulder to the front and extends downward to be plugged into the safety belt connector 121 to fix the end of the left front safety belt 124. After the other front safety belt 124 is pulled out from the second retractor 125, it passes over the shoulder from above the right shoulder to the front and extends downward to be plugged into the safety belt connector 121 to fix the end of the right front safety belt 124. In this way, the front safety belts 124 are tightened and the front of the occupant is restrained.

[0059] It should be noted that the second retractor 125 also has a self-locking function. After the occupant fastens the seat belt and inserts the front seat belt 124 into the seat belt connector 121 and fixes it, the second retractor 125 automatically tightens it, thereby restraining the occupant's shoulders and the front of the body in the two front seat belts 124.

[0060] In some embodiments, the seat belt assembly 1 further includes two second guide members 126, which are suitable for being installed at positions corresponding to the backrest of the seat 13 and above the shoulders of the occupants on both sides, and the two front seat belts 124 are respectively passed through the two second guide members 126 in a one-to-one correspondence.

The second guide member 126 is provided with a front-to-back through-guide hole 115 for the front seat belt 124 to pass through. When the two front seat belts 124 are pulled out from the second retractor 125, they pass through the corresponding two second guide members 126 respectively. The second guide members 126 have a plurality of guide holes 115 extending from front to back for the front seat belts 124 to pass through. 124 is guided so that the two front seat belts 124 are respectively led out from the corresponding guide holes 115 toward the shoulders on both sides, and then can be stretched and extended to be inserted into the front seat belt connector 121 to restrain the shoulders, chest and the entire upper body of the occupant to ensure the stability of the occupant's body. When the front seat belts 124 are not needed, the front seat belts 124 can be pulled out from the seat belt connector 121, so that the two front seat belts 124 can be automatically retracted into the second retractor 125.

[0062] Therefore, by providing the second guide member 126 to guide the front seat belts 124 , the two front seat belts 124 can be smoothly pulled out or smoothly retracted.

When the occupant's seat is adjusted rearward, the airbag body 1291 is still deployed along the front of the occupant, and the protective effect of the airbag body 1291 on the occupant will not be affected by the change in the occupant's position.

[0072] When the occupant is in a lying position, the seat 13 is facing backward and the occupant is more comfortable, but the occupant is not lying at 180 degrees to the horizontal plane. Therefore, when the airbag body 1291 in the airbag box 1292 is deployed, the whole is toward the front of the occupant and tilted upward, and after deployment, it may include a first airbag portion 1293 and a second airbag portion 1294 connected to each other. That is to say, after the airbag body 1291 is deployed at the airbag box 1292, it is toward the front of the occupant and It deploys toward the leg position and also deploys upward toward the occupant. The first airbag portion 1293 can support the occupant's legs while also supporting the second airbag portion 1294. The second airbag portion 1294 deploys upward along the first airbag portion 1293, and the positions of the seat belt connector 121 and the airbag box 1292 vary with the occupant's sitting posture. The airbag body 1291 pops out of the airbag box 1292 to protect the front of the occupant's body and the occupant's head.

[0073] like Fig.10 and Fig.11 As shown, the lower part of the airbag component 129 is the first airbag part 1293, and the upper part of the airbag component 129 is the second airbag part 1294. The first airbag part 1293 is connected to the second airbag part 1294. When the airbag body 1291 is not in use, the airbag body 1291 is stored in the airbag box 1292, wherein the shape of the airbag box 1292 is constructed to be the same as the shape of the seat belt connector 121, which is conducive to connecting with the seat belt connector 121 to form an integral structure, maintain a certain aesthetics, improve the integrity of the airbag box 1292 and the seat belt connector 121, and also make the airbag box 1292 and the seat belt connector 121 more integrated after connection. The airbag box 1292 and the seat belt connector 121 occupy the same area on the front side of the occupant's abdomen along the transverse direction of the vehicle, saving space on the front side of the occupant's abdomen along the transverse direction of the vehicle, and facilitating the protection of the front side of the occupant's body after the airbag body 1291 is deployed.

[0074] like Fig. 9 As shown, the cross-section of the seat belt connector 121 is a pentagonal structure, and five plug interfaces can be respectively set on the faces corresponding to the five sides of the pentagonal structure. The five plug interfaces can respectively correspond to one end of a lap seat belt 122, two lap seat belts 123 and two front seat belts 124. The seat belt connector 121 is set on the front side of the occupant's body to facilitate the connection of the lap seat belt 122, two lap seat belts 123 and two front seat belts 124, and also to facilitate the integrated setting of the airbag box 1292, so that the airbag body 1291 pops out from the airbag box 1292 on the front side of the occupant's body.

[0075] Of course, the cross-section of the seat belt connector 121 is not limited to being set as a pentagonal structure, but can also be set as a hexagonal structure, a heptagonal structure or other structures that are convenient for setting five connecting parts, as long as the crotch seat belt 122, two waist seat belts 123 and two front seat belts 124 can be connected to different positions of the seat belt connector 121 and the airbag box 1292 can be connected to the front side of the seat belt connector 121.

[0076] For example, the airbag box 1292 is located on the front side of the seat belt connector 121, forming a two-layer structure, that is, the front layer structure is the airbag box 1292, and the back layer structure is the seat belt connector 121, so that the connection of the seat belt and the storage and ejection of the airbag body 1291 do not affect each other.

[0077] In actual design, Fig.12 As shown, a first pull strap 1295 may be provided between the front and rear inner walls at the connection between the first cavity inside the first airbag portion 1293 and the second cavity inside the second airbag portion 1294, and a second pull strap 1296 may be provided on the front and rear inner walls of the second cavity inside the second airbag portion 1294. Thus, when the airbag body 1291 is deployed, driven by the first pull strap 1295 and the second pull strap 1296, the airbag body 1291 is deployed along the front side. The first pull strap 1295 and the second pull strap 1296 may respectively control the deployment degree of the first airbag portion 1293 and the second airbag portion 1294, thereby controlling the deployment degree of the entire airbag body 1291 in front of the occupant, which is beneficial to protecting the occupant.

[0078] Therefore, on the basis of the seven-point safety belt, with the airbag body 1291 embraced in the front, when a collision occurs, the occupant will have a forward posture under the action of the seven-point safety belt, and will not produce a large displacement in other directions. At this time, the airbag body 1291 inflates rapidly to provide additional cushioning and protection for the occupant's head and neck. That is to say, the airbag body 1291 combined with the seven-point safety belt can provide better protection for the occupant.

[0079] The utility model also provides a seat assembly 100 .

[0080] The seat assembly 100 according to the embodiment of the present invention comprises a seat 13 and the safety belt assembly 1 of any one of the above-mentioned embodiments. The seat 13 is formed with a storage groove 131 , and the safety belt connector 121 is suitable for being placed in the storage groove 131 .

[0081] Specifically, Figure 5As shown, the storage groove 131 is arranged on the side of the seat 13. After the seat belt connector 121 and the air bag box 1292 are arranged as a whole, when the seat belt assembly 1 is not needed, that is, when the occupant does not need to wear a seat belt, the overall structure formed by the seat belt connector 121 and the air bag box 1292 is placed in the storage groove 131 on the side of the seat 13 for storage, which does not take up space and is placed on the side of the seat 13, which is convenient for the occupant to place and take at hand, and is flexible and convenient. And the seat belt connector 121 and the air bag box 1292 can be retracted together at the third retractor 127 through a waist seat belt 123, that is, one waist seat belt 123 can always be connected to one connecting portion of the seat belt connector 121, that is, it is equivalent to that one waist seat belt 123 is always connected to the seat belt connector 121 and the air bag box 1292. Then, when in use, the seat belt connector 121 and the air bag box 1292 are taken out of the storage box and one end is pulled out along one side of the third retractor 127. At this time, only the other waist seat belt 123, the two front seat belts 123 and the air bag box 1292 need to be retracted. The belt 124 and a crotch seat belt 122 can continue to be connected to the other four plug interfaces of the seat belt connector 121, so that the seat belt connector 121 and the airbag box 1292 can be pulled just to the front of the occupant's body, and the seat belt connector 121 and the airbag box 1292 are reeled up on the third reel 127, thereby connecting with the seat 13, so as to avoid the seat belt connector 121 and the airbag box 1292 being placed in other places and difficult to take out when in use, and to ensure that the seat belt connector 121 and the airbag box 1292 are always a whole with the seat 13, so as to facilitate the protection of the occupant by the seat belt and the airbag body 1291.

[0082] According to the seat assembly 100 of the embodiment of the utility model, by providing a storage groove 131, the integrated safety belt connector 121 and the airbag box 1292 can be placed in the storage groove 131 for storage, and can be always connected to a waist safety belt 123 through one end of the safety belt connector 121, and the waist safety belt 123 can be reeled or pulled out of the third reel 127 by utilizing the pulling force of the third reel 127, so that the safety belt connector 121 is pulled close to the side of the seat 13 and placed in the storage groove 131 or pulled to the front side of the occupant, which is convenient and flexible for the occupant to place and take at hand.

[0083] The utility model also provides a vehicle.

[0084] The vehicle according to the embodiment of the utility model comprises the seat assembly 100 of any one of the above-mentioned embodiments. When the occupant is in a lying position, the occupant is restrained and protected by a seven-point safety belt, which comprises a first safety belt structure 11 of two shoulder safety belts 111, and a second safety belt structure 12 of a safety belt connector 121, a crotch safety belt 122, two waist safety belts 123 and two front safety belts 124, which can restrain and protect multiple parts of the occupant's body, enhance the restraint effect on the occupant's upper body, prevent the vehicle from causing damage to the occupant's spine, chest and cervical spine during a collision, and effectively protect the occupant's body safety. When the vehicle is hit, under the action of the seven-point safety belt, the occupant will have a forward posture, and at this time, the airbag will quickly inflate from the airbag box 1292 located in front of the occupant's body toward the front of the occupant's body, providing additional cushioning and protection for the occupant's head and neck.

[0085] In addition, based on the seat belt assembly 1 and the airbag, the embodiment of the utility model is also provided with a safety detection system, such as the seat 13 includes a seat 13 backrest occupant detection sensor, a seat 13 backrest angle measurement sensor, and the vehicle is also provided with a seat belt unfastened reminder system and an in-vehicle occupant detection camera.

[0086] When the vehicle is initially started, the vehicle is in gear "on". When the vehicle speed is > 0, the occupant needs to wear the four-point safety belt in a normal sitting position. If the occupant does not wear the four-point safety belt, the vehicle starts to give an audible and visual reminder until the occupant fastens the safety belt. The four-point safety belt, namely the two waist safety belts 123 and the two front safety belts 124 mentioned above, can protect the occupant in a normal sitting position.

[0087] During the operation of the vehicle, the occupant changes from a sitting position to a lying position, and the system continuously detects that when the seat 13 backrest occupant detection sensor detects that there is an occupant sitting, and the in-vehicle occupant monitoring camera determines that the occupant is in a lying position, the seat 13 backrest angle measurement sensor detects that the seat 13 backrest angle is greater than a preset angle (such as 35 degrees), where the seat 13 backrest angle is the angle between the seat 13 backrest and the vertical direction of the vehicle, the system determines that the occupant is in a lying position. Multi-dimensional judgment can ensure the stability of the system. When the system determines that the occupant is in a lying position, the system pops up the shoulder safety belt 111 and the hip safety belt 122, and prompts the occupant to fasten the seven-point safety belt. If the occupant does not fasten the seven-point safety belt, the system will continue to prompt for more than 2s to ensure that the occupant is in a safe state.

[0088] When the vehicle's front-end camera and radar detect that the vehicle is in a dangerous state, the AEB (automatic emergency braking system) is activated and the system continues to detect whether there is a collision signal. If so, the airbag body 1291 in the front airbag box 1292 will pop out quickly and be located in front of the occupant. The airbag body 1291 explodes forward and upward, and relies on the first and second straps 1295 and 1296 to adjust the length of the explosion in front of the occupant. During the collision, the occupant is restrained by the seven-point seat belt and rotates forward, and the airbag body 1291 protects the head and neck.
