Description

[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to Chinese Patent Application No. 202211399612.3, entitled "SEAT BELT APPARATUS, VEHICLE SEAT, VEHICLE, AND ADJUSTMENT METHOD FOR SEAT BELT APPARATUS," filed with the State Intellectual Property Office of the People's Republic of China on November 9, 2022, which is incorporated herein by reference in its entirety.

[0002] The present application relates to the field of vehicle technology, and in particular to seat belt systems, vehicle seats, vehicles, and adjustment methods for seat belt systems. [Background technology]

[0003] Seat belts are active safety devices on vehicles and are important for the safety protection of drivers or passengers during the driving process of a vehicle. For example, a vehicle seat belt can restrain the passenger during a collision, avoiding secondary collisions with the steering wheel or dashboard, and avoiding injuries that may occur when the passenger is ejected from the vehicle during a collision.

[0004] Currently, seat belts installed in vehicle seats typically have a three-point seat belt structure and a diagonally extending belt portion. The belt portion extends diagonally downward from one shoulder of the occupant to the other waist of the occupant. When a driver or occupant sits in a seat and fastens the seat belt, the seat belt automatically tightens, which tends to cause pressure on protruding parts such as the shoulder, and can cause discomfort or even pain when worn for a long time, resulting in a poor user experience. Summary of the Invention [Problem to be solved by the invention]

[0005] The present application provides a seat belt device, a vehicle seat, a vehicle, and an adjustment method for a seat belt device to solve the problem that a seat belt causes a feeling of pressure on protruding parts such as the shoulders, so that when a user wears a seat belt, the user feels uncomfortable and has a bad use experience. [Means for solving the problem]

[0006] According to a first aspect, the present application provides a seat belt device, including a seat belt strap, a seat belt insertion board that passes through the seat belt strap, and a seat belt buckle that snaps into contact with the seat belt insertion board. The seat belt strap includes a seat belt body, and a pressure sensing component and a pressure adjusting component disposed in the seat belt body. In this manner, when the seat belt insertion board snaps into contact with the seat belt buckle, the pressure sensing component is configured to detect a pressure value of the seat belt strap, and the pressure adjusting component is configured to adjust a pressure value of the seat belt strap.

[0007] In the present application, the pressure detection component and the pressure adjustment component are disposed on the seat belt strap. In this case, during the wearing process, the seat belt device has the ability to identify the pressure value of the seat belt strap and can perform pressure adjustment for the area where the pressure value is greater than the threshold value of the human body. Therefore, when the seat belt device is worn, the pressure value of the seat belt strap can be adaptively adjusted based on different body shape characteristics to reduce the pressure feeling on the body parts of the driver or passenger wearing the seat belt and improve the comfort of the driver or passenger wearing the seat belt. In this way, the user experience is improved.

[0008] In a possible implementation of the first aspect, multiple pressure sensing components and multiple pressure adjusting components are arranged on the seat belt strap by region. The regional distribution rules of the multiple pressure sensing components and the multiple pressure adjusting components are related to the body parts that contact the seat belt device when worn. The distribution densities of the multiple pressure sensing components and the multiple pressure adjusting components are positively correlated with the sensitivity of the body parts to pressure. In this possible implementation, the multiple pressure sensing components and the multiple pressure adjusting components are arranged on the seat belt strap by region and related to the body parts that contact the seat belt strap. Therefore, pressure information of different body parts, such as the shoulders and waist, can be obtained, and pressure adjustment can be performed on demand, which can solve the current problem of driver or passenger discomfort when wearing a seat belt (e.g., seat belt tightness). Differences in pressure thresholds that can be borne by different body parts, such as the shoulders and waist, can be monitored and adjusted by region. This allows for differentiated pressure adjustment and control on the seat belt strap, improving comfort when wearing the seat belt.

[0009] In a possible implementation of the first aspect, the pressure detection component is further configured to transmit the pressure value to the first controller. The pressure adjustment component is further configured to receive an adjustment command from the first controller and adjust the pressure value of the seat belt strap based on the adjustment command, the adjustment command being determined by the first controller based on the received pressure value.

[0010] In this possible implementation, the pressure sensing component and the pressure adjusting component communicate separately with the first controller, and the first controller instructs the pressure adjusting component to perform pressure adjustment based on the acquired pressure value, thereby improving the accuracy of the pressure adjustment.

[0011] In one example, the first controller is located in an in-vehicle infotainment system of a vehicle to which the seat belt device belongs. In this example, the first controller reuses the controller located in the in-vehicle infotainment system to adjust the pressure value of the seat belt strap.

[0012] In another example, the first controller is located on a seat belt insertion board.

[0013] Optionally, the first controller is electrically connected to both the pressure sensing component and the pressure adjusting component. The first controller is configured to adjust the pressure value of the seat belt strap through the pressure adjusting component based on the pressure value received from the pressure sensing component and the position of the pressure sensing component. In this example, the first controller disposed on the seat belt insertion board can be electrically connected to the pressure sensing component and the pressure adjusting component on the seat belt strap. This further improves the control accuracy of the pressure adjustment.

[0014] Optionally, the first controller is particularly configured to determine a pressure threshold of the body part in contact with the pressure sensing component based on the position of the pressure sensing component, and adjust the pressure value at the position of the pressure sensing component on the seat belt strap by controlling the state of the pressure adjusting component when it is determined that the received pressure value is greater than the pressure threshold of the body part in contact with the pressure sensing component. In this example, the pressure value of the seat belt strap is detected for each region, and the pressure value of the seat belt strap is adjusted based on the pressure threshold of different body parts to achieve differentiated comfort adjustment and reduce the phenomenon of users not wanting to wear a seat belt.

[0015] Optionally, the first controller is further configured to transmit the pressure value obtained from the pressure sensing component and the state of the pressure adjusting component to a second controller disposed in an in-vehicle infotainment system of the vehicle to which the seat belt device belongs when the seat belt insertion board is snap-fitted with the seat belt buckle. In this manner, the first controller disposed in the seat belt insertion board can transmit the obtained pressure value and the state of the pressure adjusting component to the second controller of the in-vehicle infotainment system, so that the second controller can implement global control. This also lays the foundation for a user to subsequently adjust the strap pressure value or store the strap pressure value through the in-vehicle infotainment system.

[0016] Optionally, the first controller is further configured to send a guide adjustment request to the second controller when the pressure value at the position of the pressure sensing component on the seat belt strap is adjusted to the adjustment threshold of the pressure adjusting component but the pressure value is still greater than the pressure threshold of the human body portion in contact with the pressure sensing component, and the guide adjustment request is used to request adjustment of the position where the seat belt strap is connected to the guide plate adjuster. In this way, when the airbag pressure on the seat belt cannot meet the human body requirements, a request is sent to the second controller of the in-vehicle infotainment system, so that the second controller can adjust the position where the seat belt strap is fastened to the guide plate adjuster. This can meet the requirements for comfortable wearing of the seat belt in special scenarios.

[0017] In a possible implementation of the first aspect, the first controller is further configured to acquire a plurality of strap pressure values ​​detected by a plurality of pressure detection components of the seat belt strap, and, if the plurality of strap pressure values ​​are greater than a pressure threshold of a human body portion in contact with a corresponding pressure detection component and the distribution rule of the plurality of strap pressure values ​​does not match the pressure distribution rule of a seat belt device that is properly worn, determine that the seat belt device is not being worn correctly and output warning information.

[0018] In this possible implementation, the seat belt device may further send warning information about the phenomenon that some drivers or passengers do not wear the seat belt device correctly, for example, a scenario in which a vehicle owner only inserts the buckle and the seat belt does not circumvent the body, to remind the driver or passenger to wear the seat belt correctly, thereby effectively reducing the phenomenon that the driver or passenger does not wear the seat belt device correctly.

[0019] In a possible implementation of the first aspect, the pressure sensing component is disposed on a first surface of the seat belt body, the first surface being a surface that contacts the user's body when the seat belt device is worn. The pressure adjusting component includes an inflation component disposed on a second surface of the seat belt body and an airbag disposed between the seat belt body and the pressure sensing component. The seat belt body is further provided with an air hole that connects the inflation component to the airbag, and the air hole is used by the inflation component to inflate and deflate the airbag.

[0020] In this application, the pressure sensing component may be a pressure sensor, and the inflation component may be an air pump. The positional relationship between the pressure sensor, the air pump, and the air bag is set to lay the foundation for realizing differentiated comfort adjustment and control of the seat belt.

[0021] Optionally, a first line is disposed on the seat belt body, and the first line is configured to electrically connect the inflation component and a power supply component disposed on the seat belt insertion board. The inflation component and the power supply component are electrically connected to each other through the first line. In this way, when the seat belt device is released, the power supply component can charge the inflation component, thereby causing the pressure value of the seat belt strap to be deflated.

[0022] Optionally, the seat belt strap further comprises an airbag packaging layer, the pressure sensing component being disposed on the airbag packaging layer, and the airbag being disposed between the seat belt body and the airbag packaging layer.

[0023] When the first controller is disposed on the seat belt insertion board, a second line connecting the pressure sensing component and the first controller is further disposed on the airbag packaging layer, and the pressure sensing component is configured to transmit the sensed pressure value to the first controller through the second line.

[0024] In this example, the airbag packaging layer may encase the airbag and attach the airbag to the seat belt body, so that the inflation component can inflate and deflate the airbag through an air hole provided in the seat belt body. A second line disposed in the seat belt body may connect the plurality of pressure sensing components to the pressure sensing components disposed in the seat belt body and a first controller disposed on the seat belt insertion board to transmit pressure signals.

[0025] In a possible implementation of the first aspect, a first snap-fit ​​portion is disposed at an end of the seat belt insertion board, an electrical connection component is disposed in the first snap-fit ​​portion, and the seat belt buckle includes a second snap-fit ​​portion that mates with the first snap-fit ​​portion.

[0026] The electrical connection component is configured to electrically connect the seat belt insertion board and the seat belt buckle when the first snap fit portion snaps into contact with the second snap fit portion.

[0027] In this possible implementation, the second snap-fit ​​portion of the seat belt buckle may include an inner spring plate. When the metal tongue of the seat belt insertion board snaps into the seat belt buckle, the inner spring plate is connected to the electrical connection component, so that the first controller can transmit the acquired pressure value and the state of the pressure adjustment component to the in-vehicle infotainment system through the electrical connection. The structures of the seat belt insertion board and the seat belt buckle in this technical solution can implement a function to detect whether the seat belt device is fastened or unfastened, can implement a function to transmit an electrical signal, and can further implement a power supply function.

[0028] According to a second aspect, the present application provides a vehicle seat including a seat belt device according to the first aspect and any one of the possible implementations.

[0029] In a possible implementation of the second aspect, the vehicle seat further includes a first fastening portion located on a first side of a seat cushion of the vehicle seat, the first fastening portion configured to fasten a first end of a seat belt strap included in the seat belt device, a second end of the seat belt strap connected to a guide plate adjustment device of a vehicle pillar, the first side being a side closer to the vehicle pillar.

[0030] In a possible implementation of the second aspect, the vehicle seat further includes a second fastening portion located on a second side of a seat cushion of the vehicle seat, the second fastening portion being configured to fasten a seat belt buckle of a seat belt device, the second side being a side away from the vehicle pillar.

[0031] In a possible implementation of the present application, the first fastening portion and / or the second fastening portion configured to fasten the seat belt device may be arranged on the vehicle seat or the vehicle, and the seat belt device is used in cooperation with the vehicle seat or the vehicle through the first fastening structure and / or the second fastening portion, thereby improving the flexibility of arranging the seat belt device.

[0032] According to a third aspect, the present application provides a vehicle including a seat belt device according to the first aspect and any one of the possible implementations.

[0033] In a possible implementation of the third aspect, the vehicle further includes a guide plate adjuster, a first fastening portion, and a second fastening portion. The guide plate adjuster is disposed at a first position on a vehicle pillar, the first fastening portion is disposed at a second position on the vehicle pillar, and the second fastening portion is connected to a seat cushion, the first position being higher than a seat back and the second position being lower than or flush with the seat cushion. The guide plate adjuster is configured to fasten a first end of a seat belt strap included in a seat belt device, the first fastening portion is configured to fasten a second end of a seat belt strap included in the seat belt device, and the second fastening portion is configured to fasten a seat belt buckle of the seat belt device.

[0034] In this possible implementation, the guide plate adjustment device, the first fastening portion, and the second fastening portion for fastening the seat belt strap are all fastened to the vehicle. In this way, the seat belt device is not affected when the vehicle seat is adjusted. This improves the independence of the seat belt strap.

[0035] Optionally, the vehicle further includes a second controller disposed in the in-vehicle infotainment system, the second controller configured to receive the pressure value detected by the pressure detection component and the state of the pressure regulating component, and to adjust the pressure value of the seat belt strap based on the pressure value and the state of the pressure regulating component.

[0036] In this possible implementation, a second controller located in the in-vehicle infotainment system may adjust the pressure value of the seat belt strap through the pressure adjustment component based on the received pressure value and the state of the pressure adjustment component.

[0037] Optionally, the second controller is further configured to adjust a position at which the seat belt strap is fastened to the guide plate adjuster when the first condition is met.

In this example, when the second controller directly communicates with the pressure sensing component and the pressure adjusting component, the second controller adjusts the pressure value of the seat belt strap multiple times based on the received pressure value and the state of the pressure adjusting component. If the pressure value of the seat belt strap still cannot meet the requirement, the second controller may determine that this may be caused by an excessively high position at which the seat belt strap is fastened to the guide plate adjusting device. In this case, the second controller may adjust the position at which the seat belt strap is fastened to the guide plate adjusting device to meet the requirements of different scenarios.

[0039] In another example, the first condition is that a guide adjustment request is received, and the guide adjustment request is used to request an adjustment of the position where the seat belt strap is connected to the guide plate adjuster. In this example, after the seat belt insertion board snaps into the seat belt buckle, the second controller can communicate with the first controller disposed on the seat belt insertion board, so that when the guide adjustment request is received, the second controller can be triggered to adjust the position where the seat belt strap is fastened to the guide plate adjuster to meet the requirements of different scenarios.

[0040] In a possible implementation of the third aspect, the in-vehicle infotainment system is further configured to display a pressure adjustment control in at least one region on the seat belt strap. The second controller is further configured to adjust the pressure value of a corresponding region on the seat belt strap when an operation on the pressure adjustment control is detected. Optionally, the pressure adjustment control may include a pressure increase control and a pressure decrease control. The pressure increase control is used to increase the strap pressure value of the corresponding region, and the pressure decrease control is used to decrease the strap pressure value of the corresponding region. Therefore, in the present application, a driver or passenger can set the strap pressure state of each region on the in-vehicle infotainment system to meet the driver's or passenger's differentiated requirements.

[0041] Optionally, the in-vehicle infotainment system is further configured to display a seat belt strap pressure setting control. The second controller is further configured to determine whether to store the current seat belt strap pressure state and perform a corresponding operation when an operation on the pressure setting control is detected. Optionally, the pressure setting control may include a storage control and a cancel control. The storage control is used to store the current strap pressure value of the area, and the cancel control is used to end the current procedure. In the present application, after setting the strap pressure state of each area of ​​the in-vehicle infotainment system, the driver or passenger may use the memory function of the in-vehicle infotainment system. In this way, the driver's or passenger's personalized requirements can be improved, and the usage experience is improved.

[0075] In the embodiments of the present application, "plurality" refers to two or more. The term "and / or" describes an association relationship for describing related objects and represents that three relationships may exist. For example, A and / or B may represent the following three cases: when only A exists, when both A and B exist, and when only B exists. The character " / " typically indicates an "or" relationship between related objects.

[0076] Vehicle seat belts are an essential safety device in vehicles and an important tool used to protect the life safety of the driver or passenger (passenger and / or driver). When a vehicle crashes, the vehicle seat belt can reduce the damage to the driver or passenger by restraining the driver's or passenger's upper body. Therefore, the driver or passenger must use the seat belt as required by regulations.

[0077] Currently, the standard form of seat belts used in vehicles is a three-point seat belt structure, specifically shown in FIG. 1. FIG. 1 is a diagram of the configuration of a three-point seat belt. As shown in FIG. 1, a three-point seat belt includes a seat belt strap 1, a seat belt insertion board 2, and a seat belt buckle 3. The seat belt insertion board 2 is disposed on the seat belt strap 1. A first end of the seat belt strap 1 is fastened to a guide plate 4, and a second end of the seat belt strap 1 is fastened to a vehicle seat 5 or a fastening portion of the vehicle (not shown in FIG. 1). The guide plate 4 may be disposed on the vehicle seat 5 or on a B-pillar of the vehicle. The fastening portion and the guide plate 4 are located on the same side of the vehicle seat 5, and the position of the guide plate 4 is higher than the position of the fastening portion. When the three-point seat belt is worn, the seat belt insertion board 2 snaps into the seat belt buckle 3.

[0078] In practical application, the three-point seat belt further includes a retractor (not shown), which is hidden in the B-pillar of the vehicle.

[0079] Optionally, Figure 2 is a diagram of the entire process of using a seat belt. As shown in Figure 2, the entire process of using a seat belt may include three stages: a boarding stage, a driving or riding stage (driving or riding), and an exiting stage.

[0080] In the boarding stage, after getting into the vehicle and sitting in the vehicle seat, the driver or passenger reaches the head of the seat belt (seat belt insertion board), then pulls the seat belt strap to an appropriate length and inserts the head of the seat belt into the buckle (seat belt buckle). The seat belt will automatically tighten after being released.

[0081] During the driving or riding phase, the driver or passenger fastens their seat belt and once the seat belt is fastened, a "fasten seat belt" prompt is provided.

[0082] During the exit phase, the driver or passenger releases the seat belt by pressing the buckle, which automatically folds the seat belt strap.

[0083] However, the above-mentioned process of using a seat belt has several problems. For example, during the boarding stage, when the driver or passenger reaches the head of the seat belt, the driver or passenger must lean to one side to reach the buckle on the upper left or upper right side, which is inconvenient. Pulling the seat belt strap to the appropriate length is inconvenient for the driver or passenger, requires a certain amount of strength, and may require multiple pulls to adjust the seat belt strap to the appropriate length. Once the head of the seat belt is inserted into the buckle, it is inconvenient for the driver or passenger to find the seat belt buckle, and inserting and aligning the buckle is inconvenient. During automatic seat belt tightening, the seat belt tightens suddenly, causing discomfort. In addition, during the driving or boarding stage, the process of fastening the seat belt also has the problem of uncomfortable seat belt fastening, as the seat belt tightens quickly and abruptly, which is likely to cause tension for the driver and passenger.

[0084] In general, discomfort in wearing a seat belt can include issues such as seat belts being too stiff, being more uncomfortable to wear in winter, feedback from drivers and passengers that the stomach of pregnant women is constricted when the seat belt is worn, and pressure on protruding parts such as the shoulders while wearing the seat belt, and discomfort or even pain when worn for long periods of time.

[0085] From the above analysis, it can be learned that most passengers and drivers do not want to wear seat belts because the above problems exist in the process of using seat belts.

[0086] However, in practical applications, seat belts are important for driving safety. For example, wearing a seat belt can reduce the fatality rate by 45% when a vehicle experiences a frontal collision, and can reduce the fatality rate by 75% when a vehicle rolls over. Therefore, based on safety protection, how to improve the comfort of the driver or passengers needs to be further considered.

[0087] Currently, seat belts tend to cause problems such as pressure, discomfort, and even pain when worn for a long time on protruding parts of the body such as the shoulders of a driver or passenger. Therefore, drivers or passengers try to improve the pressure when wearing a seat belt by adding a device such as a seat belt sheath or clamp to assist in fastening the seat belt.

[0088] For example, FIG. 3 shows a seat belt strap with an added seat belt sheath. As shown in FIG. 3, the seat belt sheath is sleeved onto the seat belt strap. The soft feature of the seat belt sheath can be used to some extent to improve the feeling of pressure of the seat belt on the driver or passenger, especially the pressure feeling on the protruding portion. However, the amount of pressure is not improved from the design of the seat belt, and the problem of discomfort when wearing it still exists. In addition, a separate device must be added for support, and it is not integrated with the seat belt, resulting in a poor user experience.

[0089] One embodiment of the present application provides a seat belt device, including a seat belt strap, a seat belt insertion board that passes through the seat belt strap, and a seat belt buckle that snaps into contact with the seat belt insertion board. The seat belt strap includes a seat belt body and a pressure detection component and a pressure adjustment component that are disposed on the seat belt body. In this manner, when the seat belt insertion board snaps into contact with the seat belt buckle, the pressure detection component can be configured to detect the pressure value of the seat belt strap, and the pressure adjustment component can be configured to adjust the pressure value of the seat belt strap. This technical solution improves the structure of the seat belt, thereby reducing the pressure sensation experienced by a driver or passenger during the process of fastening the seat belt device. For example, pressure detection technology and pressure adjustment technology are applied to the seat belt strap. In this case, during the wearing process, the seat belt device has the ability to identify the pressure value of the seat belt strap, and can perform pressure adjustment for the area where the pressure value is greater than the threshold of the human body, so that when the seat belt device is worn, the pressure value of the seat belt strap can be adaptively adjusted according to different body shape characteristics, so as to reduce the feeling of pressure on the body parts of the driver or passenger wearing the seat belt and improve the comfort of the driver or passenger wearing the seat belt, thereby reducing to a certain extent the probability of not wanting to wear the seat belt.

[0090] The technical solutions of the present application are described in detail below with reference to specific embodiments. It should be noted that some of the following specific embodiments may be combined with each other, and some embodiments may not repeatedly describe the same or similar concepts or processes.

[0091] Fig. 4 is a diagram of a structure of a seat belt device according to an embodiment of the present application. Fig. 5 is a side view of the seat belt strap of Fig. 4. Fig. 6 is a diagram of the seat belt device being worn by a driver or passenger. As shown in Figs. 4 to 6, the seat belt device includes a seat belt strap 1, a seat belt insertion board 2 that passes through the seat belt strap 1, and a seat belt buckle 3 that snaps into the seat belt insertion board 2.

[0092] See Figures 4 and 5. The seat belt strap 1 includes a seat belt body 11, a pressure sensing component 12 and a pressure adjusting component 13 disposed in the seat belt body 11.

[0093] When the seat belt insertion board 2 is snap-fit ​​with the seat belt buckle 3, the pressure detection component 12 is configured to detect the pressure value of the seat belt strap 1, and the pressure adjustment component 13 is configured to adjust the pressure value of the seat belt strap 1.

[0094] See Figure 6. When the seat belt device is worn, the seat belt strap 1 is divided into an obliquely extending portion and an abdominal restraining portion by the seat belt insertion board 2. The obliquely extending portion located on one side of the seat belt insertion board 2 extends obliquely from the shoulder on one side of the driver or passenger (the left side in the example of Figure 6) to approach the seat belt insertion board 2 at the waist on the other side of the driver or passenger (the right side in the example of Figure 6). The waist and abdominal restraining portion located on the other side of the seat belt insertion board 2 extends in the left-right direction from the waist on one side of the driver or passenger (the seat belt insertion board 2) to the waist on the other side of the driver or passenger. Optionally, a first end of the obliquely extending portion is fastened to the guide plate adjustment device 301.

[0095] It can be understood that the material of the seat belt strap 1 can be woven fabric or other materials, which is not limited in this application.

[0096] In an embodiment of the present application, in order to solve the pressure sensation caused to the human body part by the seat belt strap 1 when the driver or passenger is wearing the seat belt device, the pressure sensing component 12 and the pressure adjusting component 13 may be separately arranged on the seat belt strap 1.

[0097] When wearing the seat belt device, the pressure detection component 12 detects the pressure value of the seat belt strap 1, i.e., the pressure value of the seat belt strap 1 against the human body part. When the pressure value of the seat belt strap 1 is greater than the pressure threshold of the human body part, the pressure adjustment component 13 adjusts the pressure value of the seat belt strap 1 to reduce the pressure feeling of the seat belt strap 1 against the human body part and improve the comfort of the driver or passenger wearing the seat belt device.

[0098] Conceptually, it can be understood that in addition to the seat belt strap 1, the seat belt insertion board 2, and the seat belt buckle 3, the seat belt device may further include structural elements such as a retractor for storing the seat belt strap 1. Details will not be described herein.

[0099] Optionally, in an optional embodiment of the present application, multiple pressure sensing components 12 and multiple pressure regulating components 13 are disposed on the seat belt strap 1 for each region.

[0100] The area distribution rule of the plurality of pressure sensing components 12 and the area distribution rule of the plurality of pressure adjusting components 13 relate to the body part that comes into contact with the seat belt device when worn. The distribution density of the plurality of pressure sensing components 12 and the distribution density of the plurality of pressure adjusting components 13 are positively correlated with the pressure sensitivity of the body part.

[0101] Optionally, in one example, the pressure sensing component 12 and the pressure adjusting component 13 may be arranged in pairs, as shown in Fig. 5. In another example, the pressure sensing component 12 and the pressure adjusting component 13 may alternatively be arranged in a non-pair manner. For example, at least two pressure adjusting components 13 are configured for one pressure sensing component 12. This is not limited to the embodiments of the present application. The arrangement method may be set based on actual requirements.

[0102] For example, Figure 7 is a diagram of the distribution of pressure sensing components and pressure regulating components on a seat belt strap. As shown in Figure 7, the pressure sensing components 12 and the pressure regulating components 13 may be designed in a differentiated manner according to the region on the seat belt strap 1. This is because different parts of the human body may have different pressure sensing and discrimination capabilities and different pressure thresholds.

[0103] In daily life, in the process of wearing a seatbelt device, a driver or a passenger usually has a more obvious sense of compression on the shoulders and waist than other positions. Therefore, the area distribution rules and distribution densities of the pressure detection component 12 and the pressure adjustment component 13 can be determined based on the differences between the load-bearing threshold values of different parts of the human body. For example, at the position where the seatbelt strap 1 contacts sensitive parts of the human body such as the shoulders or waist, more pressure detection components 12 and pressure adjustment components 13 may be provided than at other positions of the seatbelt strap 1, and the pressure detection components 12 arranged at the position where the seatbelt strap 1 contacts sensitive parts of the human body such as the shoulders or waist have different pressure thresholds.

[0104] For example, different pressure thresholds, such as a pressure threshold of <aN for the shoulders, a pressure threshold of <bN for the waist, a pressure threshold of <cN for the abdomen, and a pressure threshold of <dN for the legs, are set for different parts of the human body such as the shoulders, abdomen, waist, and legs. It can be understood that the pressure threshold that can be borne by a human body part is not limited in the embodiments of the present application and can be determined based on the actual scenario. Details are not described in this specification.

[0105] For example, in the figure shown in FIG. 7, three pairs of pressure detection components 12 and pressure adjustment components 13 may be arranged at the position where the seatbelt strap 1 contacts the shoulders, and three pairs of pressure detection components 12 and pressure adjustment components 13 as well as two pairs of pressure detection components 12 and pressure adjustment components 13 may be arranged at the position where the seatbelt strap 1 contacts the waist 1, and two pairs of pressure detection components 12 and pressure adjustment components 13 may be arranged at the position where the seatbelt strap 1 contacts the waist 2. The quantity of the pressure detection components 12 and the pressure adjustment components 13 arranged at the positions where the seatbelt strap 1 contacts different parts may be set based on actual requirements. This is not limited in this specification.

[0106] In the embodiment of the present application, the distributed pressure monitoring method for the seat belt strap 1 is different from the overall pressure identification. The distributed pressure monitoring method can be used to monitor the pressure distribution in different regions and set a differential pressure standard value, for example, to mainly control pressure in areas where high pressure is felt, such as the shoulders. Regarding the distributed pressure adjustment method for the seat belt strap, the distributed pressure adjustment can ensure the independence of different regions, and the pressure adjustment by region can meet the pressure requirements of different parts and is easy to control.

[0107] The pressure sensing components and pressure adjusting components are arranged on the seat belt strap by region and associated with the body parts that contact the seat belt strap, so that pressure information of different body parts such as the shoulders and waist can be obtained, and pressure adjustment can be performed on demand to solve the current problem of drivers or passengers feeling uncomfortable wearing a seat belt (e.g., the seat belt is tightened). Differences in pressure thresholds that can be borne by different body parts such as the shoulders and waist can be monitored and adjusted by region, thereby enabling differentiated pressure adjustment and control on the seat belt strap and improving comfort when wearing the seat belt.

[0108] In an optional embodiment of the present application, the pressure sensing component 12 and the pressure adjusting component 13 may further communicate with a first controller. The first controller may be a controller disposed on the seat belt insertion board 2 or a controller disposed on the in-vehicle infotainment system of the vehicle to which the seat belt device belongs. This is not limited to the embodiment of the present application.

[0109] Correspondingly, the pressure sensing component 12 is further configured to send the pressure value to the first controller. The pressure adjusting component 13 is further configured to receive an adjustment command from the first controller and adjust the pressure value of the seat belt strap 1 based on the adjustment command, the adjustment command being determined by the first controller based on the received pressure value.

[0110] In an embodiment, after detecting the pressure value of the seat belt, the pressure detection component 12 may transmit the pressure value to the first controller, which may then adjust the pressure value of the seat belt strap 1 through the pressure adjustment component 13 based on the received pressure value.

[0111] In one example, the first controller is located in an in-vehicle infotainment system of the vehicle to which the seat belt device belongs, in which case the first controller may communicate with the pressure sensing component 12 and the pressure regulating component 13 in a wireless manner.

[0112] In another example, the first controller is located on the seat belt insertion board 2. In this case, the first controller may be electrically connected to both the pressure sensing component 12 and the pressure regulating component 13.

[0113] For example, Fig. 8 is a diagram showing the signal flow direction when the seat belt device is worn. In Fig. 8, as shown in Fig. 8, a circuit board 22 is disposed on the seat belt insertion board 2, and a first controller 220 is deployed on the circuit board 22. The first controller 220 is configured to receive a pressure value from the pressure detection component 12, and adjust the pressure value of the seat belt strap 1 through the pressure adjustment component 13 based on the pressure value received from the pressure detection component 12 and the position of the pressure detection component 12, i.e., to send an adjustment command to the pressure adjustment component 13 to adjust the state of the pressure adjustment component 13.

[0114] In practical applications, when the pressure sensing component 12 and the pressure adjusting component 13 are arranged on the seat belt strap 1 by region, the first controller 220 may be particularly configured to determine a pressure threshold of the part of the human body in contact with the pressure sensing component 12 based on the position of the pressure sensing component 12, and adjust the pressure value at the position of the pressure sensing component 12 on the seat belt strap 1 by controlling the state of the pressure adjusting component 13 when it is determined that the received pressure value is greater than the pressure threshold of the part of the human body in contact with the pressure sensing component 12.

[0115] In the embodiment, the pressure values ​​of different regions on the seat belt strap are detected through pressure detection components arranged in each region, and the pressure values ​​of the seat belt strap are adjusted for each region based on the pressure threshold of the human body part that is in contact with the seat belt strap when the seat belt device is fastened, so that the comfort of the driver or passenger wearing the seat belt device can be adjusted in a differentiated manner, thereby reducing the phenomenon that users do not want to fasten the seat belt.

[0116] 8. In this embodiment, the first controller 220 is further configured to transmit the pressure value obtained from the pressure sensing component 12 and the state of the pressure regulating component 13 to the second controller 401 when the seat belt insertion board 2 is snap-fit ​​with the seat belt buckle 3. The second controller 401 is disposed in an in-vehicle infotainment system 400 of the vehicle to which the seat belt device belongs.

[0117] In practical application, when the seat belt insertion board 2 is snap-fit ​​with the seat belt buckle 3, the seat belt device is electrically connected to the in-vehicle infotainment system 400. The first controller 220 may transmit the acquired pressure values ​​and the status of the pressure adjustment component 13 to the second controller 401 of the in-vehicle infotainment system 400 to enable the in-vehicle infotainment system 400 to display the pressure values ​​of each area on the seat belt strap 1 and / or perform pressure adjustment.

[0118] In one example, the first controller 220 is further configured to send a guide adjustment request to the second controller 401 when the pressure value at the position of the pressure sensing component 12 on the seat belt strap 1 has been adjusted to the adjustment threshold of the pressure adjusting component 13 but the pressure value is still greater than the pressure threshold of the human body part in contact with the pressure sensing component 12. The guide adjustment request is used to request adjustment of the position where the seat belt strap 1 is connected to the guide plate adjusting device 301. The guide plate adjusting device 301 is disposed on the vehicle pillar 300.

[0119] In practical applications, for special groups (e.g., based on group shape differences, the special groups account for approximately 5% of all groups) and / or special scenarios (e.g., special wearing situations), the fastening position of the seat belt device may not meet the requirements of the driver or passenger. In this case, a guide adjustment request may be sent to the second controller 401 of the in-vehicle infotainment system 400, so that the second controller 401 of the in-vehicle infotainment system 400 adjusts the position where the seat belt strap is connected to the guide plate adjuster 301 to meet the comfortable wearing of the seat belt in the special scenario.

[0120] In an embodiment of the present application, a second controller is used to adjust the position where the seat belt strap is connected to the guide plate adjustment device. As an auxiliary means for improving comfort when wearing the seat belt device, the second controller can adjust the position of the seat belt strap to help improve wearing comfort.

[0121] Optionally, in an optional embodiment of the present application, the first controller 220 obtaining a plurality of strap pressure values ​​sensed by a plurality of pressure sensing components 12 of the seat belt strap 1; If the plurality of strap pressure values ​​are greater than the pressure threshold of the human body part in contact with the corresponding pressure detection component 12, and the distribution rule of the plurality of strap pressure values ​​is not consistent with the pressure distribution rule of a properly worn seat belt system, determine that the seat belt system is not properly worn and output warning information. It is further configured as follows.

[0122] In practical applications, the seat belt device in the embodiment may further implement safety warnings in special scenarios by using pressure monitoring technology implemented by pressure sensing component 12 on seat belt strap 1. For example, when a driver or passenger is not wearing a seat belt properly (a scenario in which some vehicle owners only insert the buckle and the seat belt does not bypass the body), multiple strap pressure values ​​in multiple areas on seat belt strap 1 may be identified through pressure sensing component 12 disposed on seat belt strap 1.

[0123] Optionally, if the multiple strap pressure values ​​are greater than the pressure thresholds of the human body parts in contact with the corresponding pressure detection components, and the distribution rule of the multiple strap pressure values ​​does not match the pressure distribution rule of a seat belt device that is normally worn, for example, during normal wearing, when the shoulder pressure value is greater than the abdominal pressure value, but the shoulder strap pressure value is greater than the shoulder pressure threshold, the waist strap pressure value is greater than the waist pressure threshold, and the abdominal strap pressure value is greater than the shoulder strap pressure value (in normal cases, the abdominal strap pressure value is smaller than the shoulder strap pressure value), it is determined that the seat belt device is not worn correctly, and alarm information is output to remind the vehicle owner to wear the seat belt device correctly, so that the driver or passenger is monitored to wear the seat belt properly.

[0124] The above description optionally describes the overall function of the seat belt device. Below, the principle of how the seat belt device improves the comfort of the driver or passenger wearing the seat belt device will be described with reference to the structure of the seat belt strap 1.

[0125] Figure 9 is a diagram of the structure of a seat belt strap, where Figure 9(a) is a diagram of the first surface of the seat belt main body, Figure 9(b) is a diagram of the second surface of the seat belt main body, Figure 9(c) is a diagram of the cross section A-A' on the first surface of the seat belt main body, and Figure 9(d) is an exploded view of the seat belt main body.

[0126] See Figures 9(a) to 9(d). The pressure sensing component 12 is disposed on a first surface of the seat belt body 11. The first surface is the surface that comes into contact with the user's body when wearing the seat belt device. The pressure adjusting component 13 includes an inflation component 131 disposed on a second surface of the seat belt body 11 and an airbag 132 disposed between the seat belt body 11 and the pressure sensing component 12.

[0127] The seat belt body 11 is further provided with air holes 133 that connect the inflation component 131 to the airbag 132 , and the air holes 133 are used by the inflation component 131 to inflate and deflate the airbag 132 .

[0128] In an embodiment of the present application, as shown in Fig. 9(a), the pressure sensing component 12 may be implemented through a pressure sensor and is arranged on a first surface of the seat belt body 11 by region. From the driver's or passenger's perspective, the pressure sensing component 12 is located inside the seat belt body 11 and may be in direct contact with the user's body to perform pressure monitoring. In other words, the pressure sensing component 12 may perform signal transmission through an electrical connection.

[0129] Optionally, the pressure sensing component 12, e.g., a pressure sensor, can be made of a flexible printed circuit (FPC) material, which has characteristics such as light weight, thin profile, free bending and folding, and can be embedded on the surface of the strap to perform pressure sensing through capacitance change after deformation.

[0130] See (b), (c), and (d) of Figure 9. The inflation component 131 may be an air pump, for example, a micro air pump. The inflation components 131 are arranged in regions on the second surface of the seat belt body 11. From the driver's or passenger's point of view, the inflation components 131 are located outside the seat belt body 11. Airbags 132 are arranged in regions on the seat belt body 11. The airbags 132 are filled with air to relieve body pressure, and the airbags 132 may be returned to the seat state after being deflated. Optionally, the airbags 132 may be inflated and deflated after a signal corresponding to an adjustment command is transmitted to the inflation component 131.

[0131] For example, the expansion component 131 is implemented by a pressure principle, has a simple control function, and does not consume power. A check valve (not shown) can be disposed on the expansion component 131 to ensure no leakage after expansion.

[0132] Optionally, as shown in Fig. 8, a power supply component 23 may be further disposed on the seat belt insertion board 2. As shown in Figs. 9(c) and 9(d), a first line 14 is disposed on the seat belt body 11. The first line 14 is configured to electrically connect the inflation component 131 and the power supply component 23 disposed on the seat belt insertion board 2.

[0133] In an embodiment of the present application, the power supply component 23 disposed on the seat belt insertion board 2 is configured to supply power to the pressure adjustment component 13 disposed on the seat belt body 11. See (d) of FIG. 9. The first line 14 may electrically connect the inflation component 131 disposed on the seat belt body 11 and the power supply component 23 disposed on the seat belt insertion board 2.

[0134] Optionally, the power supply component 23 may be a rechargeable battery. The rechargeable battery may be charged through the in-vehicle infotainment system 400 when the seat belt insertion board 2 is snap-fit ​​with the seat belt buckle 3, and an electrical connection is made between the inflation component 131 and the power supply component.

[0135] Optionally, as shown in Figure 9(c), the seat belt strap 1 further includes an airbag packaging layer 15, and the pressure sensing component 12 is disposed on the airbag packaging layer 15. The airbag 132 is disposed between the seat belt body 11 and the airbag packaging layer 15.

[0136] For example, when the first controller is disposed on the seat belt insertion board 2, a second line 16 connecting the pressure sensing component 12 and the first controller is further disposed on the airbag packaging layer 15.

[0137] The pressure sensing component 12 is configured to transmit the sensed pressure value over a second line 16 to the first controller.

[0138] In an embodiment of the present application, the airbag packaging layer 15 may encase the airbag 132 and attach the airbag 132 to the seat belt body 11, so that the inflation component 131 can inflate and deflate the airbag 132 through air holes provided in the seat belt body 11. Optionally, a second line 16 disposed in the seat belt body 11 may connect the plurality of pressure sensing components 12 with the pressure sensing components 12 disposed in the seat belt body 11 and a first controller disposed in the seat belt insertion board 2 to transmit pressure signals.

[0139] For example, FIG. 10 is a diagram of the structure of a seat belt insertion board and a seat belt buckle. In this specification, FIG. 10(a) is a diagram of the second surface when the seat belt insertion board 2 is not snapped to the seat belt buckle 3, FIG. 10(b) is an exploded view of the seat belt insertion board 2, FIG. 10(c) is an enlarged view of region B in FIG. 10(a), and FIG. 10(d) is a diagram of the first surface when the seat belt insertion board 2 is snapped to the seat belt buckle 3. From the driver's or passenger's perspective, it can be understood that the first surface is the inside of the seat belt body 11. When the seat belt device is worn correctly, the first surface may be in direct contact with the user's body. The second surface is the outside of the seat belt body 11. When the seat belt device is worn correctly, the second surface usually does not come into direct contact with the user's body.

[0140] 10(a) to 10(d), a first snap-fit ​​portion 21 is disposed on an end of the seat belt insertion board 2, and an electrical connection component 211 is disposed on the first snap-fit ​​portion 21. The seat belt buckle 3 includes a second snap-fit ​​portion (not shown) that matches the first snap-fit ​​portion 21. When the first snap-fit ​​portion 21 snaps into contact with the second snap-fit ​​portion, the electrical connection component 211 is configured to electrically connect the seat belt insertion board 2 and the seat belt buckle 3.

[0141] 10(b) and (c). The first snap-fit ​​portion 21 may include a tongue connector 210, a metal tongue 212 fastened to the tongue connector 210, and an electrical connection component 211 disposed on the metal tongue 212. The tongue connector 210 may be disposed on the seat belt insertion board 2, for example, enclosed between the housings 241 and 242. In addition, the circuit board 22 and the power supply component 23 may be further disposed on the seat belt insertion board 2 between the housings 241 and 242, and devices and / or components for realizing the functions of the first controller 220 are deployed on the circuit board 22.

[0142] Optionally, the second snap-fit ​​portion of the seat belt buckle 3 may include an inner spring plate. See (d) of Figure 10. When the metal tongue 212 of the seat belt insertion board 2 snaps into the seat belt buckle 3, the inner spring plate is connected to the electrical connection component 211, so that the first controller 220 can transmit the acquired pressure value and the state of the pressure regulating component 13 to the in-vehicle infotainment system through the electrical connection.

[0143] In the embodiment of the present application, the structure of the seat belt insertion board 2 and the seat belt buckle 3 shown in FIG. 10 can implement the function of detecting whether the seat belt device is fastened or unclasped, can implement the function of transmitting an electrical signal, and can further implement a power supply function.

[0144] For example, when it is detected that a seat belt is fastened, the pressure detection components 12 arranged on the seat belt strap 1 for each region may be triggered to perform pressure detection, detect pressure values ​​of the regions on the seat belt strap 1 that are in contact with different parts of the human body, and determine whether the pressure threshold for each region has been reached. A monolithic processor and / or chip, i.e., a first controller, is arranged on the seat belt insertion board 2. As a control unit of the seat belt system, upon receiving the pressure values ​​transmitted by the pressure detection components 12, the first controller may transmit an adjustment command to the inflation component 131 based on the pressure values ​​to control the inflation component 131 to start filling the airbag 132 with air.

[0145] Optionally, the first controller 220 may further communicate with the second controller 401 of the in-vehicle infotainment system 400 to adjust the position where the seat belt strap 1 is connected to the guide plate adjuster 301. Specifically, when the pressure sensing component 12 and the pressure adjusting component 13 cooperate to operate for a certain period of time, if the strap pressure value detected by the pressure sensing component 12 still does not reach the standard value after the pressure adjusting component 13 performs adjustment multiple times, a guide adjustment request may be sent to the second controller 401 of the in-vehicle infotainment system 400 to adjust the position where the seat belt strap 1 is connected to the guide plate adjuster 301.

[0146] Optionally, when the seat belt device is released, the power supply component 23 of the seat belt insertion board 2 may supply power to the connected inflation component 131, so that the inflation component 131 controls the airbag 132 to deflate. After the airbag 132 is deflated, the thickness of the seat belt strap 1 is restored to its normal size and the retractor is retracted.

[0147] From the above analysis, it can be learned that the seat belt device provided in the embodiment of the present application includes a seat belt strap, a seat belt insertion board passing through the seat belt strap, and a seat belt buckle snap-fitted with the seat belt insertion board. A pressure detection component and a pressure adjustment component are disposed on the seat belt body of the seat belt strap. When the seat belt insertion board snap-fits with the seat belt buckle, the pressure detection component is configured to detect the pressure value of the seat belt strap, and the pressure adjustment component is configured to adjust the pressure value of the seat belt strap. In this way, the pressure value of the seat belt strap is adaptively adjusted based on different body shape characteristics to reduce the pressure feeling on the body parts when the driver and passenger wear the seat belt and improve the comfort of the driver or passenger wearing the seat belt, so as to reduce to a certain extent the probability that the driver or passenger will not want to wear the seat belt.

[0148] Referring to the seat belt device provided in the above embodiment, an embodiment of the present application further provides a vehicle seat.

[0149] For example, Fig. 11 is a diagram of a structure of a vehicle seat according to an embodiment of the present application. As shown in Fig. 11, the vehicle seat may include the seat belt device 100 in the embodiment shown in Fig. 4 to Fig. 10. For the structure and implementation principle of the seat belt device 100, please refer to the description of the embodiment shown in Fig. 4 to Fig. 10. Details of this embodiment will not be described again.

[0150] Optionally, see FIG. 11 . The vehicle seat includes a cushion 101 (which may also be called a bolster), a backrest 102, and a headrest 103. The cushion 101 is configured to primarily support the buttocks of a driver or passenger. The backrest 102 is connected to the rear of the cushion 101 in a forward / backward tilting manner and is configured to primarily support the back of the driver or passenger. In addition, the angle of the backrest 102 relative to the cushion 101 may be adjusted through a back angle adjustment mechanism (not shown), such as by tilting the backrest 102 forward, backward, or upside down. The headrest 103 is attached to an upper portion of the backrest 102 and is configured to primarily support the head and neck of the driver or passenger.

[0151] It can be understood that the cushion 101, the backrest 102, and the headrest 103 belong to the seat body. In addition to the seat body, the vehicle seat may further include another structural element, for example, a seat guide rail disposed between the vehicle floor and the seat body. This is not limited to the embodiment of the present application.

[0152] It can be understood that the vehicle seat may be a driver's seat, a passenger seat located behind the driver's seat or passenger seat, or another seat, for example, a second-row seat or a third-row seat. When the vehicle seat is a seat formed by connecting multiple seats, structural elements used to configure a seat belt device may be set by using the seats as a unit, and a corresponding seat belt device is configured by using the seats as a unit. The structures of the seat belt devices of the units may be the same or different. This description will not be described in detail.

[0153] In a possible implementation design of this embodiment, the vehicle seat may further include a first fastening portion located on a first side of a seat cushion of the vehicle seat and configured to fasten a first end of a seat belt strap 1 included in the seat belt device, the second end of the seat belt strap 1 being connected to a guide plate adjusting device 301 on a vehicle pillar 300. The first side is the side closer to the vehicle pillar 300.

[0154] In a possible implementation design of this embodiment, the vehicle seat may further include a second fastening portion located on a second side of the cushion of the vehicle seat and configured to fasten a seat belt buckle 3 of the seat belt device. The second side is a side away from the vehicle pillar 300.

[0155] It can be understood that when the vehicle seat is a driver's seat or a passenger seat, the vehicle pillar 300 connected to the second end of the seat belt strap 1 is the B-pillar of the vehicle. When the vehicle seat is a second-row seat or a third-row seat, the vehicle pillar 300 connected to the second end of the seat belt strap 1 is the C-pillar of the vehicle.

[0156] In one embodiment of the present application, the first fastening portion and the second fastening portion configured to fasten the seat belt device may be disposed in a vehicle, and the seat belt device is used with a vehicle seat or a vehicle through a fastening structure of the vehicle.

[0157] In another embodiment of the present application, in the view shown in Figure 11, the vehicle seat includes a seat belt system. However, it can be understood that as an intermediate product form, the vehicle seat may alternatively not include a seat belt system, but must be used in conjunction with a seat belt system in a vehicle.

[0158] Furthermore, an embodiment of the present application further provides a vehicle, including a seat belt device 100 shown in any one of the embodiments of Figures 4 to 10. For the structure and implementation principle of the seat belt device 100, please refer to the description of the embodiments shown in Figures 4 to 10. Details of this embodiment will not be described again.

[0159] Optionally, Figure 12 is a diagram of a structure of a vehicle pillar. As shown in Figure 12, the vehicle further includes a guide plate adjustment device 301, a first fastening portion 302, and a second fastening portion (not shown). The guide plate adjustment device 301 is disposed at a first position on the vehicle pillar 300, the first fastening portion 302 is disposed at a second position on the vehicle pillar 300, and the second fastening portion is connected to a seat cushion. The first position is higher than the seat backrest, and the second position is lower than or flush with the seat cushion.

[0160] The guide plate adjustment device 301 is configured to fasten a first end of a seat belt strap 1 included in the seat belt device 100, and the first fastening portion 302 is configured to fasten a second end of the seat belt strap 1 included in the seat belt device 100. The second fastening portion is configured to fasten a seat belt buckle 3 of the seat belt device 100.

[0161] In an embodiment of the present application, the guide plate adjusting device 301, the first fastening portion 302, and the second fastening portion may be disposed in the vehicle, so that the connection position of the seat belt device is not affected when the vehicle seat is adjusted.

[0162] In a possible implementation of the present application, the vehicle further includes a second controller 401 disposed in the in-vehicle infotainment system 400. The second controller 401 is configured to receive the pressure value detected by the pressure detection component 12 and the state of the pressure adjustment component 13, and to adjust the pressure value of the seat belt strap 1 based on the pressure value and the state of the pressure adjustment component 13.

[0163] In an embodiment of the present application, the second controller 401 may directly wirelessly communicate with the pressure sensing component 12 and the pressure adjusting component 13 disposed on the seat belt strap 1. In this way, when the seat belt insertion board 2 snaps into the seat belt buckle 3, the pressure sensing component 12 may directly send the detected pressure value to the second controller, and the pressure adjusting component 13 may send the current status of the pressure adjusting component 13 to the second controller. Correspondingly, the second controller may receive the pressure value and status of the pressure adjusting component 13 and adjust the pressure value of the seat belt strap 1 via the pressure adjusting component 13.

[0164] It can be understood that the implementation principles of the pressure regulating component 13 and the pressure sensing component 12 can be referred to the description of the preceding embodiments, and the details will not be described again in this specification.

[0165] In this possible implementation of the present application, the second controller 401 is further configured to adjust the position at which the seat belt strap 1 is fastened to the guide plate adjustment device 301 when the first condition is met.

[0166] In one example, the first condition is that the pressure value at the position of the pressure sensing component 12 on the seat belt strap 1 is adjusted to the adjustment threshold of the pressure adjusting component 13 and the pressure value is greater than the pressure threshold of the part of the human body in contact with the pressure sensing component 12.

[0167] In this example, when the second controller 401 directly communicates with the pressure sensing component 12 and the pressure adjusting component 13, the second controller adjusts the pressure value of the seat belt strap 1 multiple times based on the received pressure value and the state of the pressure adjusting component 13. However, if the pressure value of the seat belt strap 1 still cannot meet the requirements, specifically, if the pressure value at the position of the pressure sensing component 12 on the seat belt strap 1 is adjusted to the adjustment threshold of the pressure adjusting component 13 but the pressure value is still greater than the pressure threshold of the human body part in contact with the pressure sensing component 12, this may be caused by an excessively high position at which the seat belt strap 1 is fastened to the guide plate adjusting device. In this case, the second controller may be triggered to adjust the position at which the seat belt strap 1 is fastened to the guide plate adjusting device to meet the requirements of different scenarios.

[0168] In another example, the first condition is that a guide adjustment request is received, and the guide adjustment request is used to request an adjustment of the position where the seat belt strap is connected to the guide plate adjuster.

[0169] In this example, after the seat belt insertion board 2 snaps into place with the seat belt buckle 3, the second controller may communicate with the first controller located on the seat belt insertion board 2, for example, receive from the first controller the pressure value and status of the pressure adjustment component 13 acquired by the first controller, and receive a guide adjustment request from the first controller, so that when the guide adjustment request is received, the second controller may be triggered to adjust the position at which the seat belt strap 1 is fastened to the guide plate adjustment device to meet the requirements of different scenarios.

[0170] It can be understood that the trigger condition for the first controller to send a guide adjustment request to the second controller is that the first controller determines that the pressure value at the position of the pressure detection component 12 on the seat belt strap 1 has been adjusted to the adjustment threshold of the pressure adjustment component 13 and that the pressure value is greater than the pressure threshold of the part of the human body in contact with the pressure detection component 12.

[0171] In an embodiment of the present application, the seat belt device of the vehicle cooperates with the second controller of the vehicle to automatically adjust the pressure value of the seat belt strap 1 without manual operation by the driver or passenger, thereby reducing the pressure of the seat belt strap 1 on different parts of the driver's or passenger's body and improving the comfort of wearing the seat belt.

[0172] 13 is a diagram of the location of an in-vehicle infotainment system in a vehicle. As shown in FIG. 13, in an embodiment, the vehicle may further include an in-vehicle infotainment system 400.

[0173] In one embodiment of the present application, the in-vehicle infotainment system 400 of the vehicle is further configured to display a pressure adjustment control in at least one region on the seat belt strap 1. Correspondingly, the second controller is further configured to adjust the pressure value in the corresponding region on the seat belt strap 1 when an operation on the pressure adjustment control is detected.

[0174] See FIG. 13 . The in-vehicle infotainment system 400 may display a pressure adjustment control for the strap pressure value of each region, for example, a pressure adjustment control for the strap pressure value of region 1. Optionally, the pressure adjustment control may include a pressure increase control and a pressure decrease control. The pressure increase control is used to increase the strap pressure value of region 1, and the pressure decrease control is used to decrease the strap pressure value of region 1. In other words, in an embodiment, the driver or passenger may set the strap pressure status of each region on the in-vehicle infotainment system 400 to meet the differentiated requirements of the driver or passenger.

[0175] In another embodiment of the present application, the in-vehicle infotainment system 400 of the vehicle is further configured to display a pressure setting control for the seat belt strap 1. Correspondingly, the second controller is further configured to determine whether to store the current pressure state of the seat belt strap 1 and perform a corresponding operation when an operation on the pressure setting control is detected.

[0176] See FIG. 13. The in-vehicle infotainment system 400 may further display the strap pressure status of each region. For example, after the driver or passenger adjusts the strap pressure value of a region, a pop-up window may be displayed on the in-vehicle infotainment system 400. The pop-up window may include a pressure setting control. Optionally, the pressure setting control may include a store control and a cancel control. The store control is used to store the current strap pressure value of the region, and the cancel control is used to end the current action.

[0177] In other words, in the embodiment, after setting the strap pressure state of each area of ​​the in-vehicle infotainment system, the driver or passenger can use the memory function of the in-vehicle infotainment system, thus improving the personalized requirements of the driver or passenger and improving the usage experience.

[0178] For example, when a driver or passenger fastens a seat belt for the first time, strap pressure values ​​for different regions may be set through the in-vehicle infotainment system. If the passenger experiences discomfort during the process of fastening the seat belt device, the driver or passenger may actively stretch the strap. In this case, the pressure detection component may detect that the strap pressure value has decreased, and the in-vehicle infotainment system provides a memory setting function.

[0179] The vehicle provided in the embodiments of the present application can meet the differentiated detection requirements of different drivers and passengers. If the driver or passenger feels uncomfortable during the wearing process and wants to adjust it again, the adjustment can be made through a pressure adjustment component displayed on the in-vehicle infotainment system. When the pressure detection component detects a change in the pressure value of the seat belt strap, the in-vehicle infotainment system can provide a function for whether to perform storage, i.e., display a pressure setting control to prompt the driver or passenger to store the current state of the seat belt. When the driver or passenger operates the storage control, the vehicle stores the current pressure state of the strap and stores the current pressure state in the current vehicle owner account. In other words, the driver or passenger can set the strap pressure value for each area through the in-vehicle infotainment system, and the in-vehicle infotainment system can store the strap pressure value after self-adjustment during the driving process. This further meets individual needs for self-defined adjustment and storage.

[0180] The above describes a seat belt device, a vehicle seat, and a vehicle. The following describes a solution for adjusting a seat belt device by using a vehicle controller as an execution body. For contents not mentioned in the seat belt device, the vehicle seat, and the vehicle, please refer to the description of the above embodiments. The details will not be described again below.

[0181] For example, Figure 14 is a schematic flowchart of an adjustment method for a seat belt device according to one embodiment of the present application. The method is applied to a controller of a vehicle, and the controller is communicatively connected to the seat belt device in the above-mentioned embodiment. As shown in Figure 14, the method may include the following steps:

[0182] S1401: When the seat belt insertion board is snap-fitted with the seat belt buckle, the pressure value detected by the pressure detection component and the state of the pressure adjustment component are obtained.

[0183] In an embodiment of the present application, when a driver or passenger wears a seat belt device, i.e., the seat belt insertion board is snap-fitted with the seat belt buckle, the pressure detection component disposed on the seat belt strap can be triggered to start detecting the strap pressure value in the area where the pressure detection component is located. Correspondingly, after detecting the pressure value in the area where the pressure detection component is located, the pressure detection component transmits the pressure value to the vehicle controller. In this way, the controller can obtain the pressure value detected by the pressure detection component when the seat belt insertion board is snap-fitted with the seat belt buckle.

[0184] It may be understood that when the seat belt insertion board snaps into the seat belt buckle, the controller may determine the status of the pressure adjustment component based on adjustment instructions delivered to the pressure adjustment component, or, if the pressure adjustment component and the controller are able to communicate directly with each other, the controller may alternatively receive the status of the pressure adjustment component reported by the pressure detection component.

[0185] S1402: The controller detects for each region whether the pressure value is less than the pressure threshold of the corresponding region. If the pressure value is less than the pressure threshold of the corresponding region, no response is made. Or, if the pressure value is equal to or greater than the pressure threshold of the corresponding region, S1403 is executed.

[0186] S1403: When it is determined that the pressure value of the first region is greater than the pressure threshold, adjust the pressure value of the first region on the seat belt strap through the first region pressure adjusting component.

[0187] Upon obtaining the pressure value of each region from the pressure sensing component and the status of the pressure regulating component of each region, the controller may determine whether the pressure value of each region meets the comfort requirements of the user.

[0188] In one example, if the pressure value of each region on the seat belt strap is less than the pressure threshold of the corresponding region, it indicates that the pressure value of the seat belt strap meets the user's comfort requirement, in which case no response is made because no pressure adjustment needs to be made.

[0189] In another example, if the pressure values ​​of some regions on the seat belt strap are greater than the pressure threshold value for the corresponding region, for example, if the pressure value of a first region is greater than the pressure threshold value, the controller may adjust the pressure value of the seat belt strap through the pressure adjustment component based on the pressure value. For example, the controller sends an adjustment command to the pressure adjustment component to change the current state of the pressure adjustment component to adjust the pressure value of the first region on the seat belt strap.

[0190] It can be understood that the first region may be any region on the seat belt strap, which is not limited in this embodiment.

[0191] Optionally, the controller may determine a pressure threshold for the body part in contact with the pressure sensing component based on the position of the pressure sensing component, and adjust the pressure value at the position of the pressure sensing component on the seat belt strap by controlling the state of the pressure adjustment component when it determines that the received pressure value is greater than the pressure threshold for the body part in contact with the pressure sensing component.

[0192] In practical applications, different parts of the human body have different capabilities for detecting pressure distribution, so the maximum comfortable pressure that can be borne also differs. For example, the shoulders and waist may feel more pressure. Therefore, pressure thresholds for different parts of the human body may be set separately in the controller, and multiple pressure detection components and multiple pressure adjustment components may be arranged on the seat belt strap for each region. Therefore, when the seat belt insertion board is snap-fitted with the seat belt buckle, the pressure detection component in each region can detect the strap pressure value of the region where the pressure detection component is located.

[0193] In this embodiment, upon obtaining the pressure value of the pressure sensing component, the controller may determine the position of the pressure sensing component, determine the pressure threshold of the body part in contact with the pressure sensing component based on the position of the pressure sensing component, and determine whether the pressure value is less than the pressure threshold of the body part in contact with the pressure sensing component. If the pressure value is less than the pressure threshold of the body part in contact with the pressure sensing component, the controller begins to control the pressure adjusting component to adjust the pressure value at the position of the pressure sensing component on the seat belt strap. If the pressure value is equal to or greater than the pressure threshold of the body part in contact with the pressure sensing component, the controller does not respond.

[0194] S1404: Determine whether the pressure value of the first region is less than the pressure threshold, and if the pressure value of the first region is less than the pressure threshold, execute S1405, or if the pressure value of the first region is greater than or equal to the pressure threshold, execute S1406.

[0195] S1405: Stop adjusting the pressure adjusting component of the first region and keep the pressure value of the first region unchanged.

[0196] For example, the pressure regulating component may include an inflation component and an airbag, and when the pressure value of the first region is less than the pressure threshold of the first region, the controller may inflate the airbag of the first region through the inflation component of the first region, stop the inflation when the pressure value of the first region is less than the pressure threshold, and keep the filling amount of the airbag of the first region unchanged.

[0197] S1406: Continue adjusting the pressure value of the first region through the pressure adjusting component of the first region.

[0198] S1407: If the pressure value of the first region has been adjusted to the adjustment threshold of the pressure adjusting component but the pressure value of the first region is still greater than the pressure threshold, adjust the position where the seat belt strap is connected to the guide plate adjusting device.

[0199] It can be understood that in the process of adjusting the pressure value of the first region through the pressure adjustment component, the controller can periodically or in real time detect whether the pressure value of the first region is below the pressure threshold. When the pressure value of the first region is below the pressure threshold, the controller stops adjusting the pressure adjustment component in the first region and maintains the pressure value of the first region unchanged. Otherwise, the controller continues to adjust the pressure value of the first region until the pressure value of the first region is adjusted to the adjustment threshold of the pressure adjustment component.

[0200] Optionally, when the pressure value of the first region is adjusted to the adjustment threshold of the pressure adjusting component, if the pressure value of the first region still cannot meet the comfort requirements of the driver or passenger, the position at which the seat belt strap is connected to the guide plate adjusting device may be adjusted through the guide plate adjusting device attached to the vehicle pillar.

[0201] In this embodiment of the present application, when the seat belt insertion board is snap-fitted with the seat belt buckle, a pressure detection component disposed on the seat belt strap detects the pressure value of the seat belt strap, and a controller detects for each region whether the pressure value is below the pressure threshold for the corresponding region. If the pressure value of a first region is below the pressure threshold, the controller stops adjusting the pressure adjustment component in the first region and maintains the pressure value of the first region unchanged. If the pressure value of the first region is greater than the pressure threshold, the controller adjusts the pressure value of the first region on the seat belt strap through the pressure adjustment component for the first region. If the pressure value of the first region has been adjusted to the adjustment threshold of the pressure adjustment component but is still greater than the pressure threshold, the controller adjusts the position where the seat belt strap is connected to the guide plate adjustment device. In this technical solution, the pressure value of the seat belt strap can be adjusted based on the requirements of different drivers and passengers and different parts. This improves the comfort of the driver or passenger wearing the seat belt device.

[0202] In an optional embodiment of the present application, the adjustment method for a seat belt device may further include the following steps: obtaining a plurality of strap pressure values ​​sensed by a plurality of pressure sensing components of the seat belt strap; and If the plurality of strap pressure values ​​are greater than the pressure threshold of the human body part in contact with the corresponding pressure detection component and the distribution rule of the plurality of strap pressure values ​​does not match the pressure distribution rule of a properly worn seat belt device, determine that the seat belt device is not properly worn and output warning information.

[0203] Optionally, multiple pressure detection components (e.g., arranged by region) are arranged on the seat belt strap, and each pressure detection component can detect the strap pressure value of a corresponding region or position and transmit the strap pressure value to the controller. Correspondingly, the controller can obtain the strap pressure values ​​of multiple regions on the seat belt strap and analyze the distribution rule of the pressure values.

[0204] For example, in a scenario where a driver or passenger does not wear a seat belt device correctly, the controller may implement a safety warning in a special scenario through seat belt strap pressure monitoring. For example, in a scenario where some drivers or passengers only insert the buckle and the seat belt strap does not bypass the body, the multiple strap pressure values ​​are greater than the pressure threshold of the human body part in contact with the corresponding pressure detection component, and the distribution rule of the multiple strap pressure values ​​does not match the pressure distribution rule of a normally worn seat belt device (for example, the pressure value of the abdomen is usually smaller than the pressure value of the shoulder). In this case, the seat belt device may be deemed to be not worn correctly, and warning information may be output to remind the driver or passenger to wear the seat belt device correctly.

[0205] In a possible implementation of this embodiment of the present application, the controller may be disposed on the seat belt insertion board. In this case, the controller's obtaining the pressure value detected by the pressure detection component and the status of the pressure adjustment component specifically refers to receiving the pressure value from the pressure detection component and the status from the pressure adjustment component. In other words, the controller may obtain the status of the pressure adjustment component through a first line disposed on the seat belt strap and the status of the pressure detection component through a second line disposed on the seat belt strap at the seat belt insertion board.

[0206] Correspondingly, in this possible implementation, when the pressure value at the position of the pressure detection component on the seat belt strap has been adjusted to the adjustment threshold of the pressure adjustment component but the pressure value is still greater than the pressure threshold of the human body part in contact with the pressure detection component, the controller sends a guide adjustment request to a second controller, the guide adjustment request is used to request adjustment of the position where the seat belt strap is connected to the guide plate adjuster, and the second controller is a controller disposed in the vehicle's in-vehicle infotainment system.

[0207] It can be understood that if the seat belt device cannot enable the pressure value of the seat belt strap to meet the comfort requirements of the driver or passenger based on the adjustment function of the seat belt device, i.e., if the pressure value at the position of the pressure detection component on the seat belt strap is adjusted to the adjustment threshold of the pressure adjustment component, but the pressure value is still greater than the pressure threshold of the human body part in contact with the pressure detection component, auxiliary adjustment may be performed through a second controller in the in-vehicle infotainment system and a guide plate adjustment device arranged on the vehicle pillar.

[0208] For example, after receiving a guide adjustment request, the second controller may adjust the position where the seat belt strap is connected to the guide plate adjuster to meet the comfort requirements of different people or in special scenarios, for example, automatically lower or raise the position where the seat belt strap is connected to the guide plate adjuster.

[0209] In a possible implementation of this embodiment of the present application, the controller is disposed in an in-vehicle infotainment system of the vehicle. In this case, the controller acquiring the pressure value detected by the pressure detection component and the state of the pressure regulating component is specifically a step of receiving the pressure value from the pressure detection component and the state from the pressure regulating component, or a step of receiving the pressure value of the pressure detection component and the state of the pressure regulating component from a first controller, where the first controller is a controller disposed on a seat belt insertion board.

[0210] In one example, a controller located in an on-board infotainment system of a vehicle may communicate wirelessly with the pressure sensing component and the pressure regulating component, such that the controller may receive pressure values ​​sensed by the pressure sensing component directly from the pressure sensing component and may receive the current state of the pressure regulating component from the pressure regulating component.

[0211] In another example, when the first controller is disposed on the seat belt insertion board, a controller disposed on the vehicle's in-vehicle infotainment system may communicate with the first controller. In this manner, after obtaining the pressure value of the pressure sensing component and the state of the pressure regulating component, the first controller may transmit the pressure value of the pressure sensing component and the state of the pressure regulating component to the controller of the in-vehicle infotainment system, so that the controller can receive the pressure value of the pressure sensing component and the state of the pressure regulating component from the first controller.

[0212] In this possible implementation, when the first condition is met, the controller may adjust the position at which the seat belt strap is fastened to the guide plate adjuster based on the pressure value and the state of the pressure adjustment component.

[0213] In one example, the first condition is that the pressure value at the location of the pressure sensing component on the seat belt strap is adjusted to the adjustment threshold of the pressure adjustment component and the pressure value is greater than the pressure threshold of the part of the human body in contact with the pressure sensing component.

[0214] Optionally, the controller may determine whether the position at which the seat belt strap is connected to the guide plate adjuster needs to be adjusted based on the received pressure value and the state of the pressure adjustment component. For example, when the pressure value at the position of the pressure sensing component on the seat belt strap is adjusted to the adjustment threshold of the pressure adjustment component and the pressure value is greater than the pressure threshold of the body part in contact with the pressure sensing component, the controller may adjust the position at which the seat belt strap is fastened to the guide plate adjuster based on the pressure value and the state of the pressure adjustment component.

[0215] In another example, the first condition is that a guide adjustment request is received, and the guide adjustment request is used to request an adjustment of the position where the seat belt strap is connected to the guide plate adjuster.

[0216] Optionally, when determining that the adjustment of the seat belt device cannot meet the comfort requirements of the driver or passenger, the first controller disposed on the seat belt insertion board may send a guide adjustment request to the controller disposed on the in-vehicle infotainment system. Thus, upon receiving the guide adjustment request from the first controller, the controller may trigger an adjustment of the position at which the seat belt strap is fastened to the guide plate adjuster.

[0217] In an optional embodiment of the present application, the adjustment method for a seat belt device may further include the following steps: adjusting a pressure value of a corresponding area on the seat belt strap when an operation on the pressure adjustment control is detected, the pressure adjustment control being displayed through the vehicle's in-vehicle infotainment system; and / or determining whether to store a current pressure state of the seat belt strap and performing a corresponding operation when an operation on the pressure setting control is detected, the pressure setting component being displayed through the vehicle's in-vehicle infotainment system.

[0218] Optionally, refer to the diagram shown in FIG. 13. During the pressure adjustment process, a pressure adjustment control for at least one region on the seat belt strap may be displayed through the in-vehicle infotainment system. Correspondingly, the driver or passenger may operate the pressure adjustment component based on the driver's or passenger's request. For example, if the driver or passenger touches or taps a pressure increase control, the controller increases the strap pressure value for the corresponding region. If the driver or passenger touches or taps a pressure decrease control, the controller decreases the strap pressure value for the corresponding region.

[0219] In an embodiment, the driver or passenger may set the strap pressure conditions for each area on the in-vehicle infotainment system to meet the differentiated requirements of the driver or passenger.

[0220] Optionally, see the diagram shown in Figure 13. After the pressure adjustment process is completed, a seat belt strap pressure setting control may further be displayed through the in-vehicle infotainment system to prompt the driver or passenger whether to store the seat belt strap pressure setting information. For example, if the driver or passenger touches or taps the store control, the controller stores the current strap pressure value of the seat belt strap. If the driver or passenger touches or taps the cancel control, the controller ends the current process and does not store the current strap pressure value of the seat belt strap.

[0221] In an embodiment, after setting the strap pressure state of each area of ​​the in-vehicle infotainment system, the driver or passenger can use the memory function of the in-vehicle infotainment system, thus improving the driver's or passenger's personalized requirements and improving the usage experience.

[0222] In an embodiment of the present application, the device for implementing the adjustment method for a seat belt device shown in Fig. 14 may be divided into functional modules. For example, each functional module may be obtained through division based on each function, or two or more functions may be integrated into one processing module. The integrated module may be implemented in the form of hardware or in the form of a software functional module. It should be noted that in the embodiment of the present application, the division into modules is merely an example and a division of logical functions, and other divisions may be used in actual implementation.

[0223] For example, Figure 15 is a diagram of the structure of a seat belt device adjuster according to one embodiment of the present application. The seat belt device adjuster may be realized through a controller in an in-vehicle infotainment system or through a controller located on a seat belt insertion board. In this embodiment of the present application, the seat belt device adjuster is communicatively connected to the seat belt device of the previous embodiment.
