Description

Technical Field

[0001] This invention belongs to the field of vehicle seat belt technology, and particularly relates to a vehicle seat follow-up seat belt assembly, follow-up adjustment method, seat and vehicle. Background Technology

[0002] With societal progress and the rapid development of the automotive industry, traffic accidents have received increasing attention. Seat belts can reduce the severity of injuries in traffic accidents. When a car comes to a sudden stop, a seat belt ensures the body is held firmly in the seat, preventing forward lurch due to inertia. Simultaneously, the airbag deploys to absorb the remaining impact energy. Airbag deployment is instantaneous, leaving occupants no time to react. Studies indicate that deployment generates approximately 180 kg of impact force. If a seat belt is not worn before a collision, the rapid expansion of the airbag will directly impact the head and chest of the front-seat occupant, causing serious injury. The role of the seat belt is to hold the person in the seat during airbag deployment, absorb some of the impact force, and apply it to the hard areas of the chest and pelvis, preventing premature contact with the airbag.

[0003] Seat belts also play a role in restraining the movement of occupants. When a car is spun after a collision, they can effectively fix the position of the occupants, reduce displacement injuries, and prevent them from being thrown out of the car. When a vehicle is rolled over after a collision, the occupants inside the car lose their center of gravity. Seat belts can both mitigate the impact between the occupants and the roof and restrain the occupants to prevent them from being thrown out.

[0004] Currently, many automakers are introducing integrated seats, where components such as the seatbelt retractor and lower anchor point are no longer installed on the vehicle body but on the seat itself. This allows the seat to move forward or rotate without affecting the occupant's ability to wear the seatbelt. In existing technology, when the seatbelt lower anchor point structure is fixed to the seat rail, it can only be adjusted forward and backward with the rail, not vertically.

[0005] Currently, seat belts fixed to the upper and lower anchor points of the seat rail are equipped with seat covers, and the seat belts need to extend from the slots in the seat cover. As the seat height is adjusted, the seat cover rises upwards and backwards along with the seat frame, while the lower anchor points are fixed to the seat rails and do not change with the seat height. As the seat is lowered, the front end of the seat cover slots gets closer to the seat belt. In a frontal collision, the seat belt strapped to the dummy's waist and abdomen will tighten and stretch forward due to the dummy's forward inertia. The front end of the seat belt is prone to interference and friction with the seat cover during a collision, posing a risk of seat belt breakage and failure, which can cause serious injury to the occupant. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, the present invention provides a vehicle seat follow-up seat belt assembly, a follow-up adjustment method, a seat, and a vehicle. It designs a seat belt assembly that can rise and fall with the vehicle seat to solve the problem that when the lower anchor point integrated seat moves downward, the seat belt is too close to the seat cover groove, and the seat belt may break due to friction with the front end of the groove during a collision. This reduces the possibility of seat belt failure causing injury to occupants in the event of a car collision.

[0007] To achieve the above objectives, one or more embodiments of the present invention provide the following technical solutions:

[0008] The first aspect of the present invention provides a vehicle seat follow-up seat belt assembly.

[0009] A vehicle seat follow-up seat belt assembly includes a follow-up lower anchor point lifting mechanism, which includes a rivet, an outer rocker arm, and an inner rocker arm. The first end of the outer rocker arm and the first end of the inner rocker arm are fixed by a rivet, which is used to rotatably connect with the anchor point bracket. The second end of the outer rocker arm is used to connect the seat belt, and the second end of the inner rocker arm is used to connect the seat body reinforcement plate.

[0010] As an alternative technical solution, an anchor point end piece is also included, which is connected to the second end of the outer rocker arm. A seat belt is threaded through the anchor point end piece and extends out from the slot of the seat cover.

[0011] As an optional technical solution, the outer rocker arm and the inner rocker arm are respectively disposed on both sides of the anchor point bracket, 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°-120°.

[0012] As an optional technical solution, the anchor bracket is fixedly connected to the seat slide rail.

[0013] As an optional technical solution, the anchor bracket has pre-drilled anchor mounting holes, and the rivets are inserted into the anchor mounting holes.

[0014] As an optional technical solution, the second end of the inner rocker arm is provided with an opening, and the opening at the second end of the inner rocker arm is fixedly connected to the opening on the reinforcing plate of the seat body by a rotating shaft; the second end of the outer rocker arm is provided with a limiting hole, and the anchor point end piece is provided with a limiting block, and the limiting hole and the limiting block are adapted to each other.

[0015] As an alternative technical solution, the maximum rearward displacement corresponding to the maximum angle of rotation of the anchor point end piece under the drive of the follow-up lower anchor point lifting mechanism is greater than the maximum rearward displacement of the seat cover.

[0016] A second aspect of the present invention provides a seat.

[0017] The seat includes a seat body, a seat height adjustment mechanism, and a vehicle seat follow-up seat belt assembly as described in the first aspect. The seat body has a seat cover with a slot through which the seat belt of the vehicle seat follow-up seat belt assembly extends. The seat height adjustment mechanism includes a seat rail located below the seat body and connected to an anchor point bracket of the vehicle seat follow-up seat belt assembly. The seat body includes a seat body reinforcement plate connected to an inner rocker arm of the vehicle seat follow-up seat belt assembly.

[0018] A third aspect of the present invention provides a vehicle.

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

[0020] The fourth aspect of the present invention provides a method for adjusting a vehicle seat-following seat belt assembly.

[0021] The method for adjusting a vehicle seatbelt with adaptive function includes the following steps:

[0022] When the vehicle seat is adjusted downwards from its highest position, the seat body reinforcement plate moves backwards and downwards.

[0023] The seat body reinforcement plate drives the inner rocker arm to move backward and downward. The inner rocker arm and the outer rocker arm are relatively fixed in position. Then the inner rocker arm drives the outer rocker arm, the outer rocker arm drives the anchor point end piece, and the seat belt on the anchor point end piece to move backward and upward.

[0024] The end of the seat belt moves backward along the seat cover slot, so that the end of the seat belt moves away from the front end of the seat cover slot that moves backward and downward.

[0025] The above one or more technical solutions have the following beneficial effects:

[0026] This invention provides a vehicle seat follow-up seat belt assembly, a follow-up adjustment method, a seat, and a vehicle. The follow-up seat belt assembly includes a follow-up lower anchor point lifting mechanism, comprising a rivet, an outer rocker arm, and an inner rocker arm. The first end of the outer rocker arm is fixed to the first end of the inner rocker arm by the rivet, which is used for rotatable connection with the anchor point bracket. The second end of the outer rocker arm is used to connect to the seat belt, and the second end of the inner rocker arm is used to connect to the seat body reinforcement plate. Based on this principle, the seat belt lower anchor point structure (anchor point end piece structure), originally fixed to the seat rail, can rise and fall with the seat body. When the seat body is lowered, the seat belt lower anchor point structure (anchor point end piece structure) can rotate backward, increasing the distance between the seat belt and the foremost edge of the seat cover groove. This solves the problem of the seat belt being too close to the seat cover groove when the seat with an integrated lower anchor point moves downward, potentially causing breakage due to friction between the seat belt and the front end of the groove during a collision, thus reducing the possibility of injury to occupants due to seat belt failure in a car collision.

[0027] This invention can effectively improve the safety of seat anchor point seat belts, prevent the seat belt from interfering with the seat cover groove and breaking during a collision, reduce the injury to the occupant during a collision or rollover, and increase user satisfaction and product market competitiveness.

[0028] As the seat is raised and lowered, the anchor point end piece can rotate up to 80° and move backward by 63mm, which is farther than the rearward displacement of the seat cover. This effectively avoids interference between the front groove of the seat cover and the seat belt during seat movement, and makes the seat belt fit the waist of the driver and passenger more closely when the seat is lowered, resulting in better comfort.

[0029] This invention has a simple structure, is easy to operate, and has a relatively low cost. It can be installed and modified on the original seat frame, and is easy to install and highly reliable.

[0030] Advantages of additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0041] It should be noted that the following detailed descriptions are exemplary and intended to provide further illustration of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0042] It should be noted that the terminology used herein is for the purpose of describing particular implementations only and is not intended to limit the exemplary implementations of the present invention.

[0043] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0044] Example 1

[0045] This invention addresses the problem in existing technologies where the lower anchor point structure of the seat belt 7 is fixed to the seat slide rail 9, allowing only forward and backward adjustment with the slide rail, but not height adjustment. When the driver or passenger adjusts the seat height, the seat cover 8 rises along with the seat frame towards the rear and upper part of the seat, while the lower anchor point remains fixed to the seat slide rail 9 and does not change with the seat height. Conversely, when the seat height decreases, the front end of the slotted section of the seat cover 8 gets closer to the seat belt 7. In the event of a frontal collision, the seat belt 7 will tighten and stretch forward due to forward inertia. The front end of the seat belt 7 and the seat cover 8 are prone to interference and friction during the collision, posing a risk of the seat belt 7 breaking and failing, which could cause significant injury to the driver or passenger.

[0046] Therefore, the existing design of the non-adjustable lower anchor point of the seat belt 7 still poses certain safety hazards and risks. Based on this, a specific embodiment of the present invention discloses a vehicle seat-following seat belt assembly. The lower anchor point of the seat belt 7 is designed as a follow-up structure that rises and falls with the seat. Through a clever and simple structural design, when the seat is adjusted downwards from a high position, the lower anchor point of the seat belt 7 rotates backwards, increasing the distance between the seat belt 7 and the foremost edge of the seat cover 8 slot. This solves the problem in the existing technology where the seat belt 7 is too close to the seat cover 8 slot when the seat moves downwards, potentially causing it to break due to friction with the front edge of the slot during a collision. This reduces the possibility of injury to occupants due to seat belt 7 failure during a collision.

[0047] Please see Figures 1-3 As shown, where Figures 1-3 These are, respectively, an axonometric view, a front view, and a left view of the follow-up lower anchor point lifting mechanism 101 of the vehicle seat follow-up seat belt assembly in this embodiment. The follow-up 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 is fixed to the first end of the inner rocker arm 2 by the rivet 3, which is used for rotatable connection with the anchor point bracket 4. The second end of the outer rocker arm 1 is used to connect to the seat belt 7, and the second end of the inner rocker arm 2 is used to connect to the seat body reinforcing plate 6. The outer rocker arm 1 and the inner rocker arm 2 are fixed by the rivet 3, and their relative positions do not change during rotation. Therefore, during follow-up, the movement of the inner rocker arm 2 can drive the movement of the outer rocker arm 1, thereby causing the position of the seat belt 7 connected to the outer rocker arm 1 to move.

[0048] In this embodiment, the second end of the inner rocker arm 2 is the end that is far away from the first end of the inner rocker arm 2, and the second end of the outer rocker arm 1 is the end that is far away from the first end of the outer rocker arm 1. The second end of the outer rocker arm 1 is square, and the second end of the inner rocker arm 2 is arc-shaped. The square second end of the outer rocker arm 1 is provided with rounded corners, and holes are provided at the positions of the inner rocker arm 2 and the outer rocker arm 1 near the second end, so that it can be easily connected to other components.

[0049] like Figures 1-3 As shown, the angle between the second end of the outer rocker arm 1 and the second end of the inner rocker arm 2 can be set to 20°-120°, and in this embodiment, it is set to 30°. It can be understood that the first ends of the outer rocker arm 1 and the first ends of the inner rocker arm 2 are overlapped, specifically as shown... Figure 3 As shown, it is easy to fix with rivets 3.

[0050] Set a certain angle between the second end of the outer rocker arm 1 and the second end of the inner rocker arm 2, such as... Figure 4 and Figure 5 As shown, when the vehicle seat follow-up seat belt assembly of this embodiment is installed on the seat, the driver or passenger adjusts the height of the seat, causing the seat body reinforcement plate 6 to shift. The seat body reinforcement plate 6 will drive the inner rocker arm 2 to shift. Since the first end of the inner rocker arm 2 is riveted and fixed to the first end of the outer rocker arm 1 by the rivet 3, and the rivet 3 is rotatably connected to the anchor point bracket 4, the outer rocker arm 1 will also rotate along the anchor point bracket 4 under the drive of the inner rocker arm 2. There is a certain angle between the two, which can effectively change the moving direction of the seat belt 7 and the moving direction of the groove on the seat cover 8 of the seat body 14. This ensures that the moving direction of the seat belt 7 is different from the moving direction of the groove on the seat cover 8 of the seat body 14, thereby increasing the distance between the seat belt 7 and the front end of the groove of the seat cover 8. This solves the problem that the seat belt 7 is too close to the groove of the seat cover 8 when the seat moves downward, and the seat belt 7 may break due to friction with the front end of the groove during a collision.

[0051] For example, as a specific implementation, since there is a 30° angle between the second end of the outer rocker arm 1 and the second end of the inner rocker arm 2, when the driver and passenger adjust the seat to the highest position (or a higher position) and then adjust the seat height downward from the highest position, due to the existence of the included angle, the direction of movement of the seat body 14 connected to the inner rocker arm 2 is not the same as the direction of movement of the seat belt 7 connected to the outer rocker arm 1. That is to say, the position of the slot through which the seat belt 7 passes on the seat body 14 is different from the direction of movement of the seat belt 7 passing through it. Therefore, the seat belt 7 and the front end of the slot will not fit or interfere with each other, thereby avoiding serious consequences in the event of a collision or accident.

[0052] Furthermore, to better prevent the seat belt 7 from fitting too tightly or interfering with the front end of the slot, the maximum rearward displacement corresponding to the maximum angle of rotation of the anchor point end piece 5 under the drive of the follow-up lower anchor point lifting mechanism 101 is greater than the maximum rearward displacement of the seat cover 8. This facilitates the creation of a certain gap between the seat belt 7 and the front end of the slot, better ensuring the safety of the driver and passengers.

[0053] As a further technical solution, in order to better ensure that the moving position of the slot through which the seat belt 7 passes on the seat body 14 is different from the moving direction of the seat belt 7 passing through it, this embodiment can further define the specific positions of the outer rocker arm 1 and the inner rocker arm 2 in the highest position of the seat body 14:

[0054] Please refer to details. Figure 6 and Figure 7 As shown, where Figure 6 This is a schematic diagram of the vehicle's seatbelt assembly when the seat is in its highest position. Figure 7 This is a schematic diagram of the vehicle's seatbelt assembly in its lowest configuration. Figure 6 As can be seen, when the seat is in its highest position, the inner rocker arm 2, driven by the upward movement of the seat body 14, has rotated along the anchor bracket 4 to the 12 o'clock position, which is offset from the vertical direction, while the anchor end piece 5 driven by the outer rocker arm 1 has not yet reached the 12 o'clock position in the vertical direction between the anchor points.

[0055] From Figure 6 The state in Figure 7 When the seat changes position, i.e., when the driver or passenger adjusts the seat from the highest position to the lowest position, the seat body 14 moves to the lower right, and therefore, the seat body reinforcement plate 6 also moves to the lower right. Figure 6 The inner rocker arm 2 has already exceeded the 12 o'clock position in the vertical direction, so under the action of the seat body reinforcement plate 6, the inner rocker arm 2 also moves to the lower right.

[0056] At this time, 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 to the lower right, the actual direction of movement of the outer rocker arm 1 is to the upper right. Therefore, the anchor end piece 5 connected to the outer rocker arm 1 and the safety belt 7 passing through the anchor end piece 5 will also move to the upper right, thereby ensuring the difference in the direction of movement between the safety belt 7 and the safety belt 7 slot, and better ensuring the distance of the gap between the safety belt 7 and the front end of the slot.

[0057] In other embodiments, the above limitations may not be imposed; 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 the moving direction of the seat belt 7 differs somewhat from the moving direction of the slot. This embodiment does not impose any limitations in this regard.

[0058] In this embodiment, as the seat is raised or lowered, the anchor point end piece 5 can rotate up to 80° and move backward by 63mm, which is farther than the rearward displacement of the seat cover 8. This effectively avoids interference between the front groove of the seat cover 8 and the seat belt 7 during seat movement, and makes the seat belt 7 fit more snugly against the waist of the driver and passenger when the seat is lowered. This effectively improves the safety of the seat-type lower anchor point seat belt 7, prevents the seat belt 7 from interfering with the groove of the seat cover 8 and breaking during a collision, and reduces the injury to the occupant in the event of a collision or rollover.

[0059] Please see Figure 4 and Figure 5 As shown, as a further technical solution, the outer rocker arm 1 and the inner rocker arm 2 are respectively disposed on both sides of the anchor point bracket 4. The anchor point bracket 4 has pre-reserved anchor point mounting holes, and the rivet 3 passes through the anchor point mounting holes. In this embodiment, the anchor point end piece 5 is connected to the second end of the outer rocker arm 1. A seat belt 7 is passed through the anchor point end piece 5, and the seat belt 7 passes through the slot of the seat cover 8. The anchor point bracket 4 is fixedly connected to the seat slide rail 9.

[0060] The second end of the inner rocker arm 2 is provided with an opening 10, and the opening 10 at the second end of the inner rocker arm 2 is fixedly connected to the opening on the seat body reinforcing plate 6 through a rotating shaft 11; the second end of the outer rocker arm 1 is provided with a limiting hole 12, and the anchor point end piece 5 is provided with a limiting block 13, and the limiting hole 12 and the limiting block 13 are adapted to each other.

[0061] Furthermore, in this embodiment, the seat body reinforcement plate 6 is the left side reinforcement plate of the seat body.

[0062] Detailed installation method:

[0063] During installation, the outer rocker arm 1 and the inner rocker arm 2 can be riveted to the original seat anchor point fixing bracket using rivets 3. The two rocker arms can rotate around the holes in the seat fixing bracket. The outer rocker arm 1 is used to install the anchor point end piece 5, while the inner rocker arm 2 is riveted to the left reinforcing plate of the seat body. The seat can be adjusted up and down under the action of the four-bar linkage and the motor. When the seat is adjusted up and down, the inner rocker arm 2, because it is riveted to the left reinforcing plate of the seat body, moves with the reinforcing plate, driving the outer rocker arm 1 and the anchor point end piece 5 fixed on the outer rocker arm 1 to move. When the seat is adjusted down, the anchor point end piece 5 can pull the end of the seat belt 7 to move backward along the slot of the seat cover 8, so that the end of the seat belt 7 is away from the front end slot of the seat cover 8 that moves backward and downward.

[0064] For a more specific installation method in this embodiment, please refer to [link / reference]. Figure 4 As shown, the outer rocker arm 1 and the inner rocker arm 2 are installed on the seat anchor 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 ​​together at a 30° angle between the outer rocker arm 1 and the inner rocker arm 2. They are then installed in the original anchor mounting hole of the seat anchor bracket 4 and fixed with rivets 3, so that the outer rocker arm 1 and the inner rocker arm 2 can rotate around the seat anchor bracket 4.

[0065] The opening 10 on the inner rocker arm 2 is fixedly connected to the opening 10 on the seat body reinforcing plate 6 via a rotating shaft 11;

[0066] Next, align the limiting block 13 of the anchor end piece 5 with the limiting hole 12 of the outer rocker arm 1, and fix it with bolts;

[0067] Finally, install the seat belt 7 onto the anchor bracket 4 and install the seat cover 8, as follows. Figure 6 As shown, the installation of the entire vehicle seat follow-up seat belt assembly is completed.

[0068] Working principle:

[0069] The effect after installation in this embodiment is as follows: Figure 7 As shown, the seat's highest position is as follows: Figure 6 As shown. When the seat mechanism is adjusted downwards, the seat cover 8 fixed to the seat body 14 will also move backwards and downwards. The seat anchor bracket 4 is fixed to the seat slide rail 9. The up and down movement of the seat will not change the state of the anchor bracket 4. At this time, the seat body reinforcing plate 6 moves backwards and downwards, driving the inner rocker arm 2 to move backwards and downwards. The rectangular boss in the inner rocker arm 2 and the outer rocker arm 1 fixes the position of the two rocker arms relative to each other. The outer rocker arm 1 and the anchor end piece 5 fixed on it move backwards and upwards, pulling the end of the seat belt 7 to move backwards along the slot of the seat cover 8, so that the end of the seat belt 7 moves away from the front end slot of the seat cover 8 that moves backwards and downwards, realizing the movement of the lower anchor point of the seat belt 7 for adjustment.

[0070] As the seat is raised and lowered, from its highest to its lowest position, the mechanism allows the anchor point end piece 55 to rotate up to 80° and move backward by 63mm, which is further than the rearward displacement of the seat cover 8. This effectively prevents the front groove of the seat cover 8 from interfering with the seat belt 7 during seat movement, and ensures that the seat belt 7 fits more snugly against the occupant's waist when the seat is lowered, preventing the seat belt 7 from becoming too loose. In the event of a collision, insufficient restraint on the occupant's waist could cause the occupant to lurch forward, resulting in additional injury.

[0071] Example 2

[0072] This embodiment discloses a seat.

[0073] A seat includes a seat body 14, a seat height adjustment mechanism, and a vehicle seat follow-up seat belt assembly as described in Embodiment 1. The seat body 14 is provided with a seat cover 8, which has a slot through which the seat belt 7 of the vehicle seat follow-up seat belt assembly passes. The seat height adjustment mechanism includes a seat slide rail 9, which is disposed below the seat body 14 and is connected to an anchor point bracket 4 of the vehicle seat follow-up seat belt assembly. The seat body 14 includes a seat body reinforcement plate 6, which is connected to an inner rocker arm 2 of the vehicle seat follow-up seat belt assembly.

[0074] In this embodiment, the seat height adjustment mechanism also includes a motor and a four-bar linkage. The motor drives the four-bar linkage to move, thereby moving the seat body 14 along the seat slide rail 9 to raise or lower the seat.

[0075] Example 3

[0076] This embodiment provides a vehicle.

[0077] A vehicle includes a vehicle seat-following seat belt assembly as described in Embodiment 1, or includes a seat as described in Embodiment 2.

[0078] Example 4

[0079] This embodiment provides a method for adjusting a vehicle seatbelt assembly that follows the user's movements.

[0080] A method for adjusting a vehicle seatbelt assembly that follows the user's movements includes the following steps:

[0081] When the vehicle seat is adjusted downward from its highest position, the seat body reinforcement plate 6 moves backward and downward;

[0082] The seat body reinforcement plate 6 drives the inner rocker arm 2 to move backward and downward. The inner rocker arm 2 and the outer rocker arm 1 are relatively fixed in position. Then the inner rocker arm 2 drives the outer rocker arm 1, the outer rocker arm 1 drives the anchor end piece 5, and the seat belt 7 on the anchor end piece 5 to move backward and upward.

[0083] The end of the seat belt 7 moves backward along the slot of the seat cover 8, so that the end of the seat belt 7 moves away from the front end of the slot of the seat cover 8 which is moving backward and downward.

[0084] In fact, the following adjustment method of the vehicle seat following seat belt assembly in this embodiment is to ensure that the moving direction of the seat belt 7 is different from the moving direction of the seat belt 7 slot on the seat cover 8 when the seat is lowered, so as to achieve the purpose of moving the seat belt 7 away from the front end of the slot.

[0085] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
