Description

[Technical Field]

[0001] The present disclosure belongs to the technical field of vehicle seat belts, and particularly relates to a vehicle seat following seat belt assembly, a following adjustment method, a seat and a vehicle. [Background Art]

[0002] With the progress of society and the rapid development of the automobile industry, the occurrence of traffic accidents has attracted more and more attention. The use of seat belts can reduce the degree of personal injury in traffic accidents. As a main protective measure for passive safety of automobiles, according to statistics, in frontal crashes of passenger vehicles, seat belts reduce the fatality probability of vehicle occupants by 71% and the fatality probability of drivers by 77%; in side crashes of passenger vehicles, seat belts reduce the fatality probability of vehicle occupants by 67% and the fatality probability of drivers by 76%. In a frontal crash, the automobile stops rapidly, and the seat belt can ensure that the human body is fixed to the seat, preventing the human body from jerking forward due to inertia, while the airbag deploys to absorb the remaining impact energy. The deployment of an airbag occurs instantaneously, and an occupant cannot react at all. According to research, an impact force of about 180kg is generated during deployment. If a seat belt is not fastened before the crash, the huge impact force generated by the rapidly expanding airbag will directly hit the front of the head and chest of front-row occupants, causing serious injuries. The function of the seat belt is to fix the person to the seat during the deployment of the above-mentioned airbag, absorb part of the impact force, apply it to the hard chest and pelvis positions of the human body, and avoid early contact with the airbag.

[0003] Seat belts also play the role of restraining the movement of occupants. When a crashed car rotates, seat belts can well fix the position of occupants, reduce displacement injuries, and prevent occupants from being thrown out of the vehicle. When a crashed vehicle rolls over, the occupants in the vehicle lose their center of gravity. Seat belts can not only mitigate the impact process between occupants and the roof, but also restrain occupants to prevent them from being thrown out.

[0004] Currently, several automobile manufacturers are releasing integrated seats, meaning that components such as the seat belt retractor and lower anchor point have been changed from being attached to the vehicle body using conventional mounting methods to being attached to the seat itself, so that the proper fastening of the occupant's seat belt does not interfere when the seat moves forward or rotates. In conventional technology, when the lower anchor point structure of the seat belt is fixed to the seat slide rail, it can only be adjusted forward and backward according to the slide rail, and the height cannot be adjusted.

[0005] Currently, a seat cover is positioned over a seat belt that is fixed to the upper and lower anchor point structure of the seat slide rail, and the seat belt needs to extend from a slot in the seat cover. As the seat height is adjusted, the seat cover rises upward and rearward along with the seat frame, and the lower anchor point of the seat is fixed to the seat slide rail and does not change with the raising or lowering of the seat. As the seat is lowered, the front end of the slot in the seat cover approaches the seat belt, and in the event of a frontal collision with the vehicle, the seat belt, which is tied to the waist and abdomen of the dummy, will be tightened and extended forward as the dummy moves forward due to inertia. The front end of the seat belt and the seat cover are prone to interference friction during the collision, and there is a risk of the seat belt being cut and becoming ineffective, which could cause serious injury to the occupant. [Overview of the project]

[0006] To overcome the shortcomings of the prior art described above, this disclosure provides a vehicle seat-following seat belt assembly, a follow-up adjustment method, a seat, and a vehicle, and solves the problem that when a seat with an integrated lower anchor point moves downward, the seat belt is too close to the seat cover groove, which could cause the seat belt to rub against the front end of the groove and break during a collision, and reduces the possibility of the seat belt failing and injuring the occupant during a vehicle collision, by designing a seat belt assembly that can move up and down with the raising and lowering of the vehicle seat.

[0007] To achieve the above objectives, one or more embodiments of this disclosure provide the following technical solutions.

[0010] As an optional technical option, an anchor point end sheet is further included, the anchor point end sheet being connected to a second end of an outer rocker arm, a seat belt being threaded through the anchor point end sheet, and the seat belt passing through a groove in the seat cover.

[0011] As an alternative technical option, the outer rocker arm and inner rocker arm are installed on both sides of the anchor point bracket, respectively, and the angle between the second end of the outer rocker arm and the second end of the inner rocker arm is set to 20° to 120°.

[0012] As an alternative technical option, the anchor point bracket described above is fixed and connected to the seat slide rail.

[0013] As an alternative technical approach, the anchor point bracket is pre-drilled with anchor point mounting holes, and the rivets are drilled into the anchor point mounting holes.

[0014] As an alternative technical option, an opening is provided at the second end of the inner rocker arm, and the opening at the second end of the inner rocker arm and the opening in the reinforcing plate of the seat body are fixedly connected via a pivot axis, a position-limiting hole is provided at the second end of the outer rocker arm, a position-limiting block is provided on the anchor point end seat, and the position-limiting hole fits into the position-limiting block.

[0015] As an alternative technical option, the maximum rearward displacement of the anchor point end seat corresponding to the maximum rotation angle when driven by the follow-type lower anchor point lifting mechanism is greater than the maximum rearward displacement of the seat cover.

[0016] This disclosure Examples It provides seats.

[0017] The seat includes a seat body, a seat height adjustment mechanism, and a vehicle seat-following seat belt assembly as described in the first embodiment, wherein a seat cover is installed on the seat body, the seat cover is provided with a groove, the seat belt of the vehicle seat-following seat belt assembly passes through the groove, the seat height adjustment mechanism is installed below the seat body and includes a seat slide rail connected to an anchor point bracket of the vehicle seat-following seat belt assembly, and the seat body includes a reinforcing plate of the seat body connected to an inner rocker arm of the vehicle seat-following seat belt assembly.

[0018] This disclosure Examples They provide vehicles.

[0019] The vehicle includes either a vehicle seat-following seat belt assembly as described in the first embodiment, or a seat as described in the second embodiment.

[0020] This disclosure Examples This provides a method for adjusting the follow-up of a vehicle seat-following seat belt assembly.

[0021] The method for adjusting the tracking of a vehicle seat-following seat belt assembly is as follows: When the vehicle seat is adjusted downwards from its highest position, the reinforcing plate of the seat body moves in a step that moves downwards and backwards, The reinforcing plate of the seat body is driven so that the inner rocker arm moves downward and rearward, the positions of the inner and outer rocker arms are relatively fixed, and further, the inner rocker arm drives the outer rocker arm, which drives the anchor point end seat and the seat belt at the anchor point end seat to move upward and rearward, The end of the seat belt moves rearward along a slot in the seat cover, which includes a step of the end of the seat belt moving away from the front end of the groove in the seat cover that moves rearward and downward.

[0022] The proposed technology provided in this disclosure includes at least the following beneficial effects:

[0023] The present disclosure provides a vehicle seat-following seatbelt assembly, a follow-up adjustment method, a seat and a vehicle. In the vehicle seat-following seatbelt assembly, a follow-up lower anchor point lifting mechanism including a rivet, an outer rocker arm and an inner rocker arm is provided, a first end of the outer rocker arm and a first end of the inner rocker arm are fixed by the rivet, the rivet is used for being rotatably connected to an anchor point bracket, a second end of the outer rocker arm is used for being connected to a seatbelt, and a second end of the inner rocker arm is used for being connected to a reinforcing plate of a seat body. Based on this principle, through the follow-up lower anchor point lifting mechanism, the lower anchor point structure (anchor point end seat structure) of the seatbelt originally fixed to the seat slide rail can lift along with the lifting of the seat body, and when the seat body descends, the lower anchor point structure (anchor point end seat structure) of the seatbelt can rotate and move backward, increasing the distance from the seatbelt to the foremost end of the seat cover notch, solving the problem that when the lower anchor point integrated seat moves downward, the seatbelt is too close to the seat cover notch, so that the seatbelt may rub against the front end of the notch and break during a collision, and reducing the possibility that the seatbelt fails and injures an occupant during an automobile collision.

[0024] The present disclosure can effectively improve the safety of a seat-type lower anchor point seatbelt, avoid the seatbelt interfering with and being cut by the seat cover notch during a collision, reduce injuries to occupants during a collision or a rollover accident, and improve user satisfaction and the market competitiveness of products.

[0025] According to the present disclosure, as the seat lifts, the anchor point end seat can be rotated by up to 80° and moved backward by 63 mm, the backward displacement is farther relative to the seat cover, which effectively avoids interference between the front end notch of the seat cover and the seatbelt during seat movement, and enables the seatbelt to fit closer to the occupant's waist when the seat is lowered, resulting in better comfort.

[0026] The present disclosure has a simple structure, is easy to operate, has relatively low cost, can be mounted and retrofitted to an original seat bracket, is easy to install, and has high reliability.

[0027] Additional aspects and advantages of the present disclosure will be provided in the following description, will be apparent from the following description in part, or will be understood through the implementation of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] To further clarify the purpose, technical proposal, and advantages of this disclosure, embodiments of this disclosure will be described in more detail below, in conjunction with the attached drawings.

[0031] The embodiments of this disclosure are described in detail below, and examples of these embodiments are shown in the drawings, where the same or similar reference numerals throughout the text indicate the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are illustrative and are intended to be used to interpret this disclosure and should not be understood as limiting this disclosure.

[0032] In related technologies, the lower anchor point structure of the seat belt 7 is fixed to the seat slide rail 9 and can only be adjusted forward and backward according to the slide rail, but the height cannot be adjusted. When the driver or passenger adjusts the seat height, as the seat height increases, the seat cover 8 rises upward and rearward with the seat frame, and the seat belt 7 is fixed to the seat slide rail 9 and does not change with the raising and lowering of the seat. On the other hand, as the seat height decreases, the front end of the slot in the seat cover 8 comes closer to the seat belt 7, and in the event of a frontal collision with the vehicle, the seat belt 7 is tightened and extended forward due to the forward inertial movement, and interference friction is likely to occur between the front end of the seat belt 7 and the seat cover 8 during the collision, creating a risk of the seat belt 7 being cut and becoming ineffective, which could cause serious injury to the driver or passenger.

[0033] Therefore, in related technologies, designs in which the height of the lower anchor point of the seat belt 7 cannot be adjusted still present certain safety hazards and risks. Based on this, one specific embodiment of the present disclosure discloses a vehicle seat-following seat belt assembly in which the lower anchor point of the seat belt 7 is designed to be a follow-up structure that can move up and down with the raising and lowering of the seat. Through a clever and simple specific structural design, when the seat is adjusted down from a high position, the lower anchor point of the seat belt 7 rotates backward, increasing the distance from the seat belt 7 to the foremost edge of the groove in the seat cover 8. This solves the problem in the prior art where, when the original seat with an integrated lower anchor point moves downward, the seat belt 7 is too close to the groove in the seat cover 8, and there is a possibility that the seat belt 7 may rub against the front edge of the groove and break during a collision, thus reducing the possibility of the seat belt 7 failing and injuring the occupant during a vehicle collision.

[0034] In this embodiment, the vehicle seat-following seat belt assembly is applied to a vehicle seat. As shown in Figures 1 and 2, the seat includes a seat body 14 and a seat slide rail 9, the seat slide rail 9 being located below the seat body 14, and the seat body 14's height can be adjusted on the seat slide rail 9. Furthermore, when the height of the seat body 14 is lowered, the seat body 14 moves further rearward. The seat-following seat belt assembly includes an anchor point bracket 4 fixed to the seat slide rail 9 and a seat belt 7. The seat body 14 has a seat cover 8 that can move along with the movement of the seat body 14. The seat belt 7 is rotatably connected to the anchor point bracket 4 and passes through the seat cover 8.

[0035] Referring to Figures 3 to 7, the vehicle seat-following seat belt assembly further includes a following lower anchor point lifting mechanism 101, where Figures 5 to 7 are schematic axial, front, and left side views of the following lower anchor point lifting mechanism 101 of the vehicle seat-following seat belt assembly in this embodiment. The following lower anchor point lifting mechanism 101 may include a rivet 3, an outer rocker arm 1, and an inner rocker arm 2, the first end of the outer rocker arm 1 and the first end of the inner rocker arm 2 being fixed by the rivet 3, the rivet 3 being used to rotatably connect to an anchor point bracket 4, the second end of the outer rocker arm 1 being used to connect to a seat belt 7, and the second end of the inner rocker arm 2 being used to connect to a reinforcing plate 6 of the seat body. The outer rocker arm 1 and the inner rocker arm 2 are fixed together by rivets 3, and their relative positions do not change during the rotation process. Therefore, the movement of the inner rocker arm 2 during the tracking process can drive the movement of the outer rocker arm 1, and further move the position of the seat belt 7 connected to the outer rocker arm 1.

[0036] In this embodiment, the second end of the inner rocker arm 2 is the end that separates from the first end of the inner rocker arm 2, the second end of the outer rocker arm 1 is the end that separates from the first end of the outer rocker arm 1, the second end of the outer rocker arm 1 is rectangular, the second end of the inner rocker arm 2 is arc-shaped, a rounded corner is provided at the second end of the rectangular outer rocker arm 1, and holes are provided at positions close to the second ends of both the inner rocker arm 2 and the outer rocker arm 1, thus making connection with other parts very easy.

[0037] As shown in Figures 5 and 6, the angle between the second end of the outer rocker arm 1 and the second end of the inner rocker arm 2 may be set to 20° to 120°, and in this embodiment, it is set to 30°. Specifically, as shown in Figure 7, the first end of the outer rocker arm 1 and the first end of the inner rocker arm 2 are installed overlapping, which facilitates fixing with rivets 3.

[0038] As shown in Figures 1 to 4, setting a certain angle between the second end of the outer rocker arm 1 and the second end of the inner rocker arm 2 is necessary because, when the vehicle seat-following seat belt assembly of this embodiment is attached to the seat, the driver or passenger adjusts the seat height, displacing the reinforcing plate 6 of the seat body, which in turn drives the displacement of the inner rocker arm 2, causing the inner rocker arm 2 to rotate. The first end of the inner rocker arm 2 and the first end of the outer rocker arm 1 are riveted together and fixed by a rivet 3, and the rivet 3 is rotatably connected to the anchor point bracket 4. Therefore, when the inner rocker arm 2 is driven, the rivet 3 rotates along the anchor point bracket 4, causing the outer rocker arm 1 to also rotate along the anchor point bracket 4, thereby driving the lower anchor point of the seat belt 7 to move. A certain angle exists between the outer rocker arm 1 and the inner rocker arm 2, which effectively changes the direction of movement of the seat belt 7 and the direction of movement of the groove in the seat cover 8 of the seat body 14. This ensures that the direction of movement of the seat belt 7 and the direction of movement of the groove in the seat cover 8 of the seat body 14 are different, thereby increasing the distance from the seat belt 7 to the foremost end of the groove in the seat cover 8. This solves the problem that when the seat moves downward, the seat belt 7 is too close to the groove in the seat cover 8, and may break due to friction with the front end of the groove during a collision.

[0039] For example, in one specific implementation, a 30° angle exists between the second end of the outer rocker arm 1 and the second end of the inner rocker arm 2. Therefore, when the driver and passenger adjust the seat height downwards from the highest position after adjusting it to the highest position, the direction of movement of the seat body 14 connected to the inner rocker arm 2 and the direction of movement of the seat belt 7 connected to the outer rocker arm 1 are different. That is, the position of the groove through which the seat belt 7 passes in the seat body 14 (the groove in the seat cover 8) is different from the direction of movement of the seat belt 7 passing through it. Consequently, the seat belt 7 and the front end of the groove do not come into close contact or interfere with each other, thereby avoiding serious consequences in the event of a collision or accident.

[0040] The outer rocker arm 1 and the seat belt 7 are connected by an anchor point end sheet 5, which is connected to the second end of the outer rocker arm 1. The seat belt 7 is threaded through the anchor point end sheet 5 and passes through a groove in the seat cover 8. Furthermore, to better prevent the seat belt 7 from being in close contact or interfering with the front end of the groove, the maximum rearward displacement of the anchor point end sheet 5, corresponding to the maximum rotation angle when the follow-type lower anchor point lifting mechanism 101 is driven, is greater than the maximum rearward displacement of the seat cover 8. In this way, it is easy to create a certain gap between the seat belt 7 and the front end of the groove, thereby better ensuring the safety of the driver and passengers.

[0041] As a further technical consideration, in order to better ensure that the movement position of the groove through which the seat belt 7 passes in the seat body 14 is different from the direction in which the seat belt 7 passes through it, in this embodiment, the specific positions of the outer rocker arm 1 and the inner rocker arm 2 can be further limited when the seat body 14 is in its highest position.

[0042] Specifically, refer to Figures 1 and 2, where Figure 1 is a schematic diagram of the vehicle seat-following seat belt assembly in its highest position, and Figure 2 is a schematic diagram of the vehicle seat-following seat belt assembly in its lowest position. As can be seen from Figure 1, in the highest position, the inner rocker arm 2 has already rotated along the anchor point bracket 4 in a direction offset from 12 o'clock vertically, driven by the upward movement of the seat body 14, and the anchor point end seat 5 driven by the outer rocker arm 1 at this time has not yet reached the 12 o'clock vertical direction along the space between the anchor points. When switching from the state in Figure 1 to the state in Figure 2, that is, when the driver or passenger adjusts the seat from the highest to the lowest position, the seat body 14 moves downward to the right, and therefore the reinforcing plate 6 and seat cover 8 of the seat body also move downward to the right, as shown in Figure 1. 1 Since the inner rocker arm 2 has already moved beyond the 12 o'clock position in the vertical direction, the inner rocker arm 2 also moves downward to the right due to the drive of the reinforcing plate 6 of the seat body. In this case, since the outer rocker arm 1 has not yet reached the 12 o'clock position in the vertical direction, as the inner rocker arm 2 drives the outer rocker arm 1 to rotate downward to the right, the actual direction of movement of the outer rocker arm 1 is upward to the right. Consequently, the anchor point end sheet 5 connected to the outer rocker arm 1 and the seat belt 7 drilled in the anchor point end sheet 5 also move upward to the right, thereby ensuring a difference in the direction of movement between the seat belt 7 and the groove of the seat cover 8, and better ensuring the gap distance between the seat belt 7 and the front end of the groove.

[0043] In other embodiments, the above limitations do not need to be imposed, and it is sufficient to ensure that the angle difference between the inner rocker arm 2 and the outer rocker arm 1 is appropriate, and that there is a certain difference between the direction of movement of the seat belt 7 and the direction of movement of the groove. In contrast, this embodiment does not impose any limitations.

[0044] In this embodiment, as the seat is raised or lowered, the anchor point end seat 5 can be rotated up to 80° and moved 63mm backward. This displacement is further backward than the seat cover 8, effectively avoiding interference between the front end groove of the seat cover 8 and the seat belt 7 during seat movement. Furthermore, when the seat is lowered, the seat belt 7 is brought into closer contact with the occupant's waist, effectively improving the safety of the seat-type lower anchor point seat belt 7. This prevents the seat belt 7 from interfering with the groove of the seat cover 8 and being cut during a collision, thereby reducing injuries sustained by the occupant during a collision or runaway rollover.

[0045] Referring to Figures 3 and 4, as a further technical proposal, the outer rocker arm 1 and the inner rocker arm 2 are installed on both sides of the anchor point bracket 4, the anchor point mounting holes are pre-drilled in the anchor point bracket 4, the rivets 3 are drilled into the anchor point mounting holes, the anchor point end sheet 5 of this embodiment is connected to the second end of the outer rocker arm 1, the seat belt 7 is drilled into the anchor point end sheet 5, the seat belt 7 passes through the groove of the seat cover 8, and the anchor point bracket 4 is fixedly connected to the seat slide rail 9.

[0046] An opening 10 is provided at the second end of the inner rocker arm 2, and the opening 10 at the second end of the inner rocker arm 2 and the opening in the reinforcing plate 6 of the seat body are fixedly connected via a rotating shaft 11. A position limiting hole 12 is provided at the second end of the outer rocker arm 1, and a position limiting block 13 is provided on the anchor point end seat 5. The anchor point end seat 5 is fixedly connected to the second end of the outer rocker arm 1 by fitting the position limiting hole 12 into the position limiting block 13.

[0047] Furthermore, in this embodiment, the reinforcing plate 6 of the seat body is the left reinforcing plate of the seat body.

[0048] The specific installation method is as follows:

[0049] Specifically, when installing, the outer rocker arm 1 and inner rocker arm 2 can be attached to the original seat anchor point fixing bracket (anchor point bracket 4) by riveting them together with rivets 3. The outer rocker arm 1 and inner rocker arm 2 can rotate around the seat fixing bracket hole. The outer rocker arm 1 is used to attach the anchor point end seat 5, and the inner rocker arm 2 is riveted to the left reinforcing plate of the seat body (seat body reinforcing plate 6). The seat can be adjusted up and down by the action of a four-link mechanism and motor. When the seat is adjusted up and down, the inner rocker arm 2 is riveted to the left reinforcing plate of the seat body and moves with the reinforcing plate, driving the movement of the outer rocker arm 1 and the anchor point end seat 5 fixed to the outer rocker arm 1. When the seat is adjusted down, the anchor point end seat 5 pulls the end of the seat belt 7 and moves rearward along the slot of the seat cover 8, moving the end of the seat belt 7 away from the front end groove of the seat cover 8 which moves rearward and downward.

[0050] More specifically, the specific mounting method of this embodiment is shown in Figure 3. The outer rocker arm 1 and the inner rocker arm 2 are attached to the seat anchor point bracket 4. The square block on the outer rocker arm 1 and the square groove of the circular boss on the inner rocker arm 2 are spliced ​​so that the outer rocker arm 1 and the inner rocker arm 2 form a 30° angle, and are mounted in the original anchor point mounting hole of the seat anchor point bracket 4. They are further secured by rivets 3, allowing the outer rocker arm 1 and the inner rocker arm 2 to rotate around the seat anchor point bracket 4. The opening 10 in the inner rocker arm 2 and the opening 10 in the reinforcing plate 6 of the seat body are fixed and connected by the rotating shaft 11. Furthermore, the position limiting block 13 of the anchor point end seat 5 is aligned with the position limiting hole 12 of the outer rocker arm 1 and fixed with a bolt. Finally, the seat belt 7 is attached to the anchor point bracket 4 and the seat belt 7 is threaded through the anchor point end seat 5. The seat cover 8 is then attached, and the seat belt 7 is passed through the groove in the seat cover 8, completing the installation of the entire vehicle seat-following seat belt assembly as shown in Figures 1 and 2.

[0051] Operating principle: The effects of this embodiment after installation are shown in Figures 1 and 2, with the seat in its highest position shown in Figure 1. When the seat mechanism is adjusted downward, the seat cover 8 fixed to the seat body 14 also moves downward and rearward accordingly, and the seat anchor point bracket 4 is fixed to the seat slide rail 9. The vertical movement of the seat does not change the state of the anchor point bracket 4. At this time, the reinforcing plate 6 of the seat body moves downward and rearward, driving the inner rocker arm 2 to move downward and rearward. The inner rocker arm 2 and the outer rocker arm 1 are connected by rivets 3, so the positions of the inner rocker arm 2 and the outer rocker arm 1 are relatively fixed. The outer rocker arm 1 and the anchor point end seat 5 fixed on it move upward and rearward, pulling the end of the seat belt 7 and moving it backward along the slot of the seat cover 8, moving the end of the seat belt 7 away from the front end groove of the seat cover 8 that is moving downward and rearward, thereby realizing the movement of the lower anchor point of the seat belt 7.

[0052] The mechanism, in the process of adjusting the seat from its highest to lowest position as the seat is raised or lowered, uses an anchor point end seat. 5 It can be rotated up to 80° and moved 63mm backward, and the displacement is further backward than the seat cover 8, effectively avoiding interference between the front groove of the seat cover 8 and the seat belt 7 during seat movement, and when lowering the seat, the seat belt 7 is more tightly attached to the occupant's waist, preventing the seat belt 7 from becoming too loose or sliding downward due to insufficient restraint of the occupant's waist during a collision, which could further injure the occupant.

[0053] This embodiment discloses a seat.

[0054] The seat, as shown in Figures 1 and 2, includes a seat body 14, a seat height adjustment mechanism, and a vehicle seat-following seat belt assembly. A seat cover 8 is installed on the seat body 14, and a groove is provided in the seat cover 8. The seat belt 7 of the vehicle seat-following seat belt assembly passes through the groove. The seat height adjustment mechanism is installed below the seat body 14 and includes a seat slide rail 9 connected to an anchor point bracket 4 of the vehicle seat-following seat belt assembly. The seat body 14 includes a reinforcing plate 6 of the seat body connected to an inner rocker arm 2 of the vehicle seat-following seat belt assembly.

[0055] In this embodiment, the seat height adjustment mechanism further includes a motor and a four-link mechanism, the motor drives the displacement of the four-link mechanism, thereby driving the seat body 14 to move along the seat slide rail 9, and achieving the objective of raising or lowering the seat.

[0056] This embodiment provides a vehicle.

[0057] A vehicle that includes the above-mentioned vehicle seat-following seat belt assembly, or a vehicle that includes the above-mentioned seat.

[0058] This embodiment provides a method for adjusting the tracking of a vehicle seat-following seat belt assembly.

[0059] A method for adjusting the tracking of a vehicle seat-following seat belt assembly, the following: When the vehicle seat is adjusted downwards from its highest position, the reinforcing plate 6 of the seat body moves in a step that moves downwards and rearwards, The reinforcing plate 6 of the seat body drives the inner rocker arm 2 to move downward and rearward, fixing the relative positions of the inner rocker arm 2 and the outer rocker arm 1. Furthermore, the inner rocker arm 2 drives the outer rocker arm 1, causing the outer rocker arm 1 to drive the anchor point end seat 5 and the seat belt 7 at the anchor point end seat 5 to move upward and rearward. The end of the seat belt 7 moves rearward along a slot in the seat cover 8, which includes a step of the end of the seat belt 7 moving away from the front end of the groove in the seat cover 8 that moves rearward and downward.
