Description

Technical Field

[0001] This invention belongs to the field of automotive parts technology, specifically relating to a seat belt assembly and a vehicle. Background Technology

[0002] Among automotive safety devices, the seat belt is one of the most important and commonly used safety equipment used to protect the safety of drivers and passengers.

[0003] In related technologies, seat belts are installed on the side of the vehicle body, that is, the seat belts are installed on the side of the seat. However, in related technologies, the guide opening of the seat belt is arranged parallel to the length direction of the vehicle body. When the seat is adjusted forward, it will block the guide opening of the seat belt, which will reduce the space for the seat belt to be pulled out and affect the smoothness of the seat belt being pulled out. Summary of the Invention

[0004] This invention aims to at least partially address one of the technical problems in related technologies. To this end, embodiments of this invention provide a seatbelt assembly that improves the smoothness of seatbelt deployment.

[0005] An embodiment of the present invention also proposes a vehicle.

[0007] The seatbelt assembly of this invention, by installing a guide ring on the car seat, allows the seatbelt webbing to adhere to the side back of the car seat 300, facilitating the user to pull out the seatbelt and thus making it easier to put on. Even after the car seat is adjusted forward, the seatbelt can still be pulled out from the side back to complete the wearing process, avoiding the inability to pull out the seatbelt due to the seat obstructing the seatbelt guide opening, thereby improving the smoothness of seatbelt pull-out. Furthermore, the guide ring extends along the width of the vehicle body, allowing the seatbelt to be pulled out in the fore-and-aft direction, consistent with the fore-and-aft adjustment direction of the seat. Compared to seatbelt guide devices in related technologies that extend in the fore-and-aft direction, this avoids the seatbelt webbing twisting at the guide device, further improving the smoothness of seatbelt pull-out.

[0008] In some embodiments, the guide ring includes a guide portion and a fixing portion, the fixing portion being detachably connected to the vehicle seat, the guide portion having a guide hole through which the seat belt passes.

[0011] In some embodiments, the guide ring further includes an elastic portion connected to the first guide segment or the second guide segment, the elastic portion being disposed within the guide hole, the elastic portion and the fixing portion being arranged at intervals in the height direction of the vehicle body, and the elastic portion extending along the width direction of the vehicle body.

[0012] In some embodiments, the seat belt assembly further includes a housing disposed on the rear side of the seat and connected to the side body of the vehicle. The retractor is located inside the housing, and a guide opening is provided on the housing and extends along the width direction of the vehicle body. One end of the seat belt extends out of the guide opening.

[0013] In some embodiments, the housing has a pressing part on the side adjacent to the seat belt, the pressing part extends along the width direction of the vehicle body, and the end face of the pressing part adjacent to the seat belt is an arc-shaped surface.

[0014] In some embodiments, the seat belt assembly further includes a guide frame located between the retractor and the guide ring, and the guide frame is arranged adjacent to the seat relative to the retractor, the guide frame having a guide groove through which the seat belt passes.

[0015] In some embodiments, the side end face of the guide groove adjacent to the guide opening is an upwardly convex arc-shaped surface, and the seat belt contacts the arc-shaped surface.

[0016] In some embodiments, the seat belt includes a first belt segment, a second belt segment, and a third belt segment connected in sequence. The first belt segment is located between the retractor and the guide frame, the second belt segment is located between the housing and the guide ring, and the third belt segment passes through the guide ring and extends along a side away from the guide ring.

[0042] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0043] like Figures 1 to 13 As shown, the seat belt assembly 100 of this embodiment includes a retractor 1, a guide ring 2, and a seat belt 3. The retractor 1 is adapted to be connected to the side body 200, and the guide ring 2 is adapted to be connected to the car seat 300. The guide ring 2 is along the width direction of the vehicle body (e.g., ...). Figure 1 As shown in the left-right direction, one end of the seat belt 3 is connected to the retractor 1, and the other end of the seat belt 3 passes through the guide ring 2. The extension direction of the guide ring 2 and the extension direction of the seat belt 3 have a first preset angle A, and 75°≤A≤105°.

[0044] like Figures 1 to 5As shown, the retractor 1 is installed on the side body 200 of the vehicle body, and the retractor 1 is located on the rear side of the car seat 300. The guide ring 2 is installed on the back of the car seat 300, and the guide ring 2 and the retractor 1 are on the same side of the same seat. The guide ring 2 extends in the left and right direction. One end of the seat belt 3 is connected to the retractor 1, and the other end of the seat belt 3 passes through the guide ring 2. A locking tongue (not shown) is provided on the side of the seat belt 3 that passes through the guide ring 2. A buckle is installed on the side of the car seat 300 opposite to the guide ring 2. The locking tongue can be inserted into the buckle to form the wearing of the three-point seat belt 3.

[0045] Specifically, such as Figure 9 As shown, the guide ring 2 extends in the left-right direction, and the seat belt 3 extends in the front-back direction. The first preset angle A between the extension direction of the guide ring 2 and the extension direction of the seat belt 3 can be 75°, 80°, 85°, 90°, 95°, 100°, or 105°. When the first preset angle is too small, the seat belt 3 is prone to excessive offset from one side of the guide ring 2 during the pulling process, causing the seat belt 3 to twist or fold within the guide ring 2, affecting the smoothness of the seat belt 3 being pulled out. When the first preset angle is too large, it is easy for the seat belt to shift towards the side of the vehicle body 200, affecting the fit between the seat belt 3 and the user, and affecting the comfort and safety of wearing the seat belt 3.

[0046] The seat belt assembly 100 of this embodiment of the invention, by installing a guide ring 2 on the car seat 300, allows the webbing of the seat belt 3 to be attached to the side back of the car seat 300, making it easier for the user to pull out the seat belt 3, thus facilitating the wearing of the seat belt 3. After the car seat 300 is adjusted forward, the seat belt 3 can still be worn by pulling out the seat belt 3 from the side back, avoiding the inability to pull out the seat belt 3 due to the seat obstructing the guide opening 51 of the seat belt 3, thereby improving the smoothness of pulling out the seat belt 3. Furthermore, the guide ring 2 extends along the width direction of the vehicle body, allowing the seat belt 3 to be pulled out in the front-back direction, consistent with the front-back adjustment direction of the seat. Compared with the seat belt 3 guide device in related technologies that extends in the front-back direction, this can prevent the webbing of the seat belt 3 from twisting at the guide device, further improving the smoothness of pulling out the seat belt 3.

[0047] In some embodiments, the guide ring 2 includes a guide portion 21 and a fixing portion 22. The fixing portion 22 is detachably connected to the car seat 300. The guide portion 21 is provided with a guide hole 211 through which the seat belt 3 passes.

[0048] Specifically, such as Figure 7 and Figure 8As shown, the lower end of the guide portion 21 is connected to the fixing portion 22. The guide portion 21 has an annular guide hole 211 that extends in the left-right direction. The end of the seat belt 3 away from the retractor 1 passes through the guide hole 211. The fixing portion 22 is detachably mounted on the frame of the car seat 300, which facilitates the installation and removal of the guide ring 2. Furthermore, the installation angle and position of the guide ring 2 can be adjusted according to the vehicle model.

[0049] In some embodiments, the seat belt assembly 100 further includes a connector 4, and the fixing part 22 is provided with a countersunk hole 221, the countersunk hole 221 being along the height direction of the vehicle body (e.g., Figure 8 The connecting member 4 passes through the fixed part 22 in the vertical direction shown in the figure and is inserted into the countersunk hole 221 to connect the guide ring 2 to the car seat 300, and the connecting member 4 is completely placed in the countersunk hole 221.

[0050] Specifically, such as Figure 8 As shown, the connector 4 extends downward through the fixing part 22 and into the frame of the car seat 300 to connect the guide ring 2 and the car seat 300. The upper end of the connector 4 is located in the countersunk hole to prevent the upper end of the connector 4 from protruding from the countersunk hole 221 and scratching the seat belt 3.

[0051] For example, there are multiple connectors 4, and the number of countersunk holes 221 is the same as the number of connectors 4. Multiple connectors 4 correspond one-to-one with multiple countersunk holes 221. By setting multiple connectors 4, the connection stability between the guide ring 2 and the car seat 300 can be improved.

[0052] Alternatively, the fixing part 22 can be connected to the car seat 300 frame by a snap-fit ​​mechanism. For example, a buckle is provided at the lower end of the fixing part 22, and a slot is provided on the car seat 300 frame. The buckle snaps into the slot to connect the guide ring 2 to the car seat 300.

[0053] In some embodiments, the guide portion 21 includes a first guide segment 212 and a second guide segment 213, the first guide segment 212 and the second guide segment 213 being connected to the fixing portion 22 respectively, the first guide segment 212, the second guide segment 213 and the fixing portion 22 forming a guide hole 211, and the side of the first guide segment 212 away from the fixing portion 22 and the side of the second guide segment 213 away from the fixing portion 22 have a gap in the width direction of the vehicle body.

[0054] Specifically, such as Figure 7As shown, the lower ends of the first guide section 212 and the second guide section 213 are respectively connected to the fixing part 22. The upper ends of the first guide section 212 and the upper ends of the second guide section 213 have a gap in the left and right direction. By setting the gap, it is easy for the seat belt to disengage from the guide ring 21. Due to the existence of this gap, the first guide section 212 and the second guide section 213 can have a certain amount of elastic displacement in the left and right direction. When the seat belt is dragged, the guide ring 21 can be elastically displaced with the left and right movement of the seat belt, thereby reducing the twisting and deformation of the seat belt.

[0055] For example, the first guide section 212, the second guide section 213 and the fixing part 22 are integrally formed, which improves the structural strength of the guide ring 21.

[0056] In some embodiments, the guide ring 2 further includes an elastic portion 23, which is connected to the first guide segment 212 or the second guide segment 213. The elastic portion 23 is disposed in the guide hole 211. The elastic portion 211 and the fixing portion 22 are arranged at intervals in the height direction of the vehicle body, and the elastic portion 23 extends along the width direction of the vehicle body.

[0057] Specifically, such as Figure 3 As shown, the elastic part 23 is provided inside the guide hole 211. For example, the left end of the elastic part 23 can be connected to the first guide section 212. The elastic part 23 extends in the left-right direction, and there is a gap between the right end of the elastic part 23 and the second guide section 213. The elastic part 23 also has a gap with the fixing part 22 in the up-down direction. The seat belt 3 is located between the elastic part 23 and the first guide section 212 and the second guide section 213, which reduces the jumping of the seat belt 3 in the up-down direction and improves the smoothness of pulling out the seat belt 3.

[0058] In some embodiments, the seat belt assembly 100 further includes a housing 5 located on the rear side of the seat and connected to the side body 200. The retractor 1 is located inside the housing 5. A guide opening 51 is provided on the housing 5 and extends along the width direction of the vehicle body. One end of the seat belt 3 extends out of the guide opening 51.

[0059] Specifically, such as Figure 1 , Figure 4 , Figure 6 and Figure 10 As shown, the housing 5 is connected to the side body 200. The guide opening 51 is located at the front end of the housing 5 and extends in the left-right direction. The rear end of the seat belt 3 extends into the housing 5 and is connected to the retractor 1. The front end of the seat belt 3 passes through the guide opening 51. It should be noted that the housing 5 and the seat are spaced apart in the front-rear direction, and the housing 5 is located behind the seat. The width of the seat belt 3 is in the left-right direction, and the width of the seat belt 3 is smaller than the dimension of the guide opening 51 in the left-right direction.

[0060] Optionally, when the seat belt assembly 100 is installed on the right side of the vehicle body 200, the housing 5 is connected to the right side of the vehicle body 200.

[0061] For example, the housing 5 can be made of plastic or metal.

[0062] In this embodiment of the invention, the pull-out direction of the seat belt 3 is the front-to-back direction, and the extension direction of the guide opening 51 is the left-to-right direction. The pull-out direction of the seat belt 3 is nearly perpendicular to the guide opening 51. Compared with the related technology where the guide opening 51 extends in the front-to-back direction so that the pull-out direction of the seat belt 3 is nearly parallel to the guide opening 51, the seat belt 3 in this embodiment of the invention avoids twisting at the position of the guide opening 51 when pulled out, thus improving the smoothness of the seat belt 3 being pulled out.

[0063] In this embodiment of the invention, the pull-out direction of the seat belt 3 is set almost perpendicularly to the guide opening 51, so that the size of the guide opening 51 in the left-right direction is smaller than the size of the guide opening 51 in the front-back direction in the related art. By reducing the opening size of the guide opening 51, the problem of the internal structure of the seat belt assembly 100 being seen through is avoided, and the aesthetics of the seat belt assembly 100 are improved.

[0064] It is understood that, in this embodiment of the invention, the seat belt assembly 100, by providing a housing 5 behind the seat and opening a guide opening 51 on the housing 5, with the guide opening 51 extending in the left-right direction, compared to the related art where the guide opening 51 extends in the front-back direction, ensures that the seat belt assembly 100 does not reduce the pull-out space of the seat belt 3 when the seat moves back and forth, thus facilitating the pull-out of the seat belt 3 and improving the smoothness of the pull-out of the seat belt 3.

[0065] In some embodiments, the housing 5 is provided with a pressing part 52 on the side adjacent to the seat belt 3. The pressing part 52 extends along the width direction of the vehicle body, and the end face of the pressing part 52 adjacent to the seat belt 3 is an arc-shaped surface.

[0066] Specifically, such as Figure 11 As shown, the pressing part 52 is located at the lower end of the housing 5. The rear side of the pressing part 52 is connected to the housing 5. The lower end of the pressing part 52 is an arc-shaped surface. By setting the pressing part 52, the height of the seat belt 3 when it is pulled out can be reduced, thereby improving the smoothness of pulling out the seat belt 3.

[0067] In some embodiments, the seat belt assembly 100 further includes a guide frame 6 located between the retractor 1 and the guide ring 2, and the guide frame 6 is arranged adjacent to the seat relative to the retractor 1. The guide frame 6 has a guide groove 61 through which the seat belt 3 passes.

[0068] Specifically, such as Figure 11 and Figure 13 As shown, the guide frame 6 is located in front of the retractor 1 and is arranged near the seat. The seat belt 3 extends out of the retractor 1 and passes through the guide groove 61 and the guide opening 51 in sequence. The guide frame 6 guides the pull-out direction of the seat belt 3, changes the movement path of the seat belt 3, reduces the friction between the seat belt 3 and the guide opening 51, and improves the smoothness of the seat belt 3 pull-out.

[0069] In some embodiments, the side end face of the guide groove 61 adjacent to the guide port 51 is an upwardly convex arc-shaped surface, and the safety belt 3 is in contact with the arc-shaped surface.

[0070] Specifically, such as Figure 11 and Figure 13 As shown, the upper surface of the front side of the guide groove 61 is an upwardly convex arc surface. The lower surface of the seat belt 3 is in contact with the arc surface, which can reduce the friction between the seat belt 3 and the guide groove 61, so that the seat belt 3 can smoothly extend out of the guide groove 61.

[0071] In some embodiments, the guide frame 6 includes a frame 62, a first baffle 63, and a second baffle 64. The first baffle 63 and the second baffle 64 are respectively connected to the frame 62, and the first baffle 63 and the second baffle 64 are arranged opposite to each other in the width direction of the vehicle body, and the first baffle 63 and the second baffle 64 are arranged along the height direction of the vehicle body (e.g., along the height direction of the vehicle body). Figure 11 Extending in the vertical direction (as shown), the first baffle 63, the second baffle 64, and the frame 62 form a guide groove 61.

[0072] Specifically, such as Figure 13 As shown, the frame 62 extends in the left-right direction, and the first baffle 63 and the second baffle 64 both extend in the up-down direction. The first baffle 63 and the second baffle 64 are arranged at intervals in the left-right direction, and the left end of the frame 62 is connected to the front end of the first baffle 63, and the right end of the frame 62 is connected to the front end of the second baffle 64. The first baffle 63, the second baffle 64 and the frame 62 form a guide groove 61 that opens towards the retractor 1, so that the safety belt 3 can pass through the guide groove 61.

[0073] In some embodiments, the frame 62, the first baffle 63, and the second baffle 64 are integrally formed.

[0074] Specifically, the integral molding of the first baffle 63, the second baffle 64 and the frame 62 can improve the structural strength of the guide frame 6, thereby improving the structural strength of the seat belt assembly 100.

[0075] In some embodiments, the seat belt 3 includes a first belt segment 31, a second belt segment 32, and a third belt segment 33 connected in sequence. The first belt segment 31 is located between the retractor 1 and the guide frame 6. The second belt segment 32 is located between the housing 5 and the guide ring 2. The third belt segment 33 passes through the guide ring 2 and extends along the side away from the guide ring 2. The first belt segment 31 has a second preset angle with the length direction of the vehicle body, and the second belt segment 32 has a third preset angle with the length direction of the vehicle body.

[0076] Specifically, such as Figure 11 and Figure 12 As shown, the first belt segment 31 is located within the receiving cavity and between the retractor 1 and the guide frame 6. The extension direction of the first belt segment 31 has a second preset angle with the longitudinal direction of the vehicle body. The second belt segment 32 is located between the housing 5 and the guide ring 2, and the extension direction of the second belt segment 32 has a third preset angle with the longitudinal direction of the vehicle body. The angle between the extension direction of the first belt segment 31 and the longitudinal direction of the vehicle body facilitates the guide frame 6 in guiding the pull-out direction of the seat belt 3. Similarly, the angle between the extension direction of the second belt segment 32 and the longitudinal direction of the vehicle body facilitates the guide ring 2 and the guide opening 51 in guiding the pull-out direction of the seat belt 3.

[0077] Optionally, the guide frame 6 and the retractor 1 are arranged at intervals in the vertical direction, and the guide frame 6 is positioned above the retractor 1 so that there is a height difference between the guide frame 6 and the retractor 1. This creates an angle between the first belt segment 31 located between the retractor 1 and the guide frame 6 and the front-rear direction of the vehicle body. The guide frame 6 guides the pull-out direction of the seat belt 3, further improving the smoothness of the seat belt 3 pull-out.

[0078] In some embodiments, the second preset included angle is B, and 0°≤B≤30°, and / or the third preset included angle is C, and 0°≤C≤30°.

[0079] For example, the range of the second preset included angle B can be 0°, 15°, 20°, 25° or 30°, and the range of the third preset included angle C can be 0°, 15°, 20°, 25° or 30°.

[0080] It should be noted that the values ​​of the second preset angle and the third preset angle can be the same or different.

[0081] For example, when the second preset angle is equal to 0°, the guide frame 6 and the retractor 1 are at the same height. When the second preset angle is greater than 30°, the height difference between the guide frame 6 and the retractor 1 is too large, and the friction between the seat belt 3 and the guide frame 6 increases. When the second preset angle is set between 0° and 30°, it ensures that the guide frame 6 guides the pull-out direction of the seat belt 3 while improving the smoothness of the pull-out of the seat belt 3.

[0082] Similarly, when the third preset angle is equal to 0°, the housing 5 and the guide ring 2 are at the same height. When the third preset angle is greater than 30°, the height difference between the housing 5 and the guide ring 2 is too large, and the friction between the seat belt 3 and the housing 5 or between the seat belt 3 and the guide ring 2 increases. When the third preset angle is set between 0° and 30°, it ensures that the guide ring 2 and the guide opening 51 guide the pull-out direction of the seat belt 3 while improving the smoothness of the pull-out of the seat belt 3.

[0083] In some embodiments, the extension direction of the seat belt 3 and the extension direction of the guide port 51 have a fourth preset angle D, and 80°≤D≤100°.

[0084] Specifically, as shown in the figure, when the second preset angle is less than 80° or greater than 100°, the friction between the seat belt 3 and the guide opening 51 will increase. In this embodiment of the invention, by setting the fourth preset angle between 80° and 100°, the friction between the seat belt 3 and the guide opening 51 is reduced, and the smoothness of pulling out the seat belt 3 is improved.

[0085] In some embodiments, the guide opening 51 has a dimension of F in the vehicle width direction, the seat belt 3 has a width of E, and 6mm≤FE≤10mm.

[0086] Specifically, such as Figure 9 As shown, the guide opening 51 has a dimension of F in the left-right direction, and the seat belt 3 has a width of E. The dimension of the guide opening 51 in the left-right direction is larger than the width of the seat belt 3 to facilitate the pulling out of the seat belt 3. Moreover, by limiting the difference between the dimension of the guide opening 51 in the left-right direction and the width of the seat belt 3, this embodiment of the invention ensures that the seat belt 3 can be pulled out smoothly while reducing the size of the guide opening 51, avoiding the problem of the internal structure of the seat belt assembly 100 being seen through, thereby improving the aesthetics of the seat belt assembly 100.

[0087] Optionally, when the difference between the left-right dimension of the guide opening 51 and the width of the seat belt 3 is less than 6mm, the gap between the seat belt 3 and the guide opening 51 is too small, which easily increases the friction between the seat belt 3 and the guide opening 51, making it difficult for the seat belt 3 to be pulled out smoothly. When the difference between the left-right dimension of the guide opening 51 and the width of the seat belt 3 is greater than 10mm, the seat belt 3 is prone to sliding and twisting within the guide opening 51, reducing the smoothness of pulling out the seat belt 3. This embodiment of the invention sets the difference between the left-right dimension of the guide opening 51 and the width of the seat belt 3 between 6mm and 10mm to ensure smooth pulling out of the seat belt 3 while reducing the size of the guide opening 51.

[0088] In this embodiment of the invention, the guide opening 51 extends in the left-right direction, and the pull-out direction of the seat belt 3 is set in the front-back direction. This makes the size of the guide opening 51 in the left-right direction smaller than the size of the guide opening 51 in the front-back direction in the related art. Furthermore, by limiting the difference between the size of the guide opening 51 in the left-right direction and the width of the seat belt 3, the size of the guide opening 51 is reduced while ensuring that the seat belt 3 can be pulled out smoothly, thereby improving the aesthetics of the seat belt assembly 100.
