Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a seating device for a vehicle. Background Technology

[0002] For vehicles equipped with two rows of seats, the rear seats can be mounted on the vehicle floor via two guide rail assemblies, allowing the position of the rear seats to be adjusted as needed.

[0003] In some cases, the rear seats are typically one-piece seats with two or three seats. With such long rear seats, the seat belts exert a large pulling force on the rear seats during a vehicle collision, and the guide rail assembly is easily damaged due to the large tensile force. Summary of the Invention

[0004] To address the aforementioned technical problems, this application proposes a seat assembly for a vehicle. The seat assembly includes a seat assembly and a guide rail system. The seat assembly is adapted to slide along a first direction. The seat assembly includes multiple seat belts and a backrest extending along a second direction parallel to the length direction of the seat assembly. The backrest is provided with multiple belt outlets for the multiple seat belts, and the multiple belt outlets are spaced apart along the second direction. The guide rail system includes multiple guide rail assemblies extending along the first direction and spaced apart along the second direction. Each of the multiple guide rail assemblies corresponds to a multiple belt outlet. Each guide rail assembly includes a fixed rail and a movable rail slidably engaged with the fixed rail, and the seat assembly is connected to the movable rail.

[0005] In one embodiment, a locking element is provided on one of the fixed rail and the moving rail, and an engagement structure that matches the locking element is provided on the other. The locking element is adapted to engage with the engagement structure, thereby locking the corresponding guide rail assembly, or the locking element is adapted to disengage from the engagement structure, thereby unlocking the corresponding guide rail assembly.

[0006] In one embodiment, the engagement structure includes a plurality of locking windows constructed on a fixed rail, the plurality of locking windows being spaced apart along a first direction. A locking element is disposed on a moving rail and includes a locking tooth seat and locking teeth extending from the locking tooth seat toward the locking window. The locking teeth are adapted to engage with a corresponding locking window to lock the corresponding rail assembly, or to disengage from the locking window to unlock the corresponding rail assembly.

[0007] In one embodiment, the guide rail system comprises three guide rail assemblies spaced apart along a second direction, with the third guide rail assembly positioned between the first and second guide rail assemblies along the second direction. Lock teeth have a first width along a first direction, and each lock window has a second width along the first direction. In the third guide rail assembly, the first width is smaller than the second width.

[0008] In one embodiment, in the third guide rail assembly, the ratio of the first width to the second width is between 1.6 and 2.

[0009] In one embodiment, in the first guide rail assembly and the second guide rail assembly, the first width is equal to the second width.

[0010] In one embodiment, the locking element further includes a resilient reset element, the two ends of which are connected to the moving rail and the locking tooth seat, respectively. When the locking tooth disengages from the corresponding lock window, the reset element is tensioned; and the reset element is adapted to return to its original position to drive the locking tooth seat until the locking tooth engages with the corresponding lock window.

[0011] In one embodiment, the moving rail is configured with a receiving space, and a guide groove is formed on the side wall of the receiving space facing the fixed rail. The locking member is movably disposed within the receiving space, and locking teeth extend from the receiving space toward the lock window via the guide groove.

[0012] In one embodiment, the guide rail system comprises three guide rail assemblies spaced apart along a second direction, with the third guide rail assembly positioned between the first and second guide rail assemblies along the second direction. At least one of the first, second, and third guide rail assemblies has a moving rail provided with either a connecting seat or a connecting pin, and the seat assembly has the other connecting seat or a connecting pin. The connecting seat defines a receiving space, and the connecting pin passes through the receiving space and connects to the connecting seat.

[0013] In one embodiment, the connector includes a first arm and a second arm that are spaced apart from each other along a first direction, and a first connecting rod and a second connecting rod connected between the first arm and the second arm. The first connecting rod and the second connecting rod are spaced apart and together with the first arm and the second arm define a receiving space. A connecting pin is clamped between the first connecting rod and the second connecting rod and is spaced apart from the first arm and the second arm along the first direction.

[0014] In one embodiment, a first elastic pad is provided between the connecting pin and the first connecting rod, with the connecting pin in close contact with the first elastic pad; and / or a second elastic pad is provided between the connecting pin and the second connecting rod, with the connecting pin in close contact with the second elastic pad.

[0015] In one embodiment, connecting holes are provided on both the first and second arms. The second connecting rod is constructed as a bolt, which is adapted to pass through the two connecting holes to connect with the first and second arms.

[0016] In one embodiment, the first arm, the second arm, and the first connecting rod are integrally formed.

[0017] In one embodiment, the moving rail of at least one of the first guide rail assembly, the second guide rail assembly, and the third guide rail assembly is rigidly connected to the seat assembly.

[0018] In one embodiment, each guide rail assembly is provided with a locking motor, which is adapted to drive the corresponding locking element to engage or disengage with the corresponding engagement structure.

[0019] In one embodiment, each guide rail assembly is provided with a drive motor, which is adapted to drive the corresponding moving rail to slide relative to the fixed rail along a first direction.

[0020] In one embodiment, the guide rail system comprises three guide rail assemblies spaced apart along a second direction, with the third guide rail assembly positioned between the first and second guide rail assemblies along the second direction. A locking motor is provided on one of the third and first guide rail assemblies, and the locking motor drives a locking element on the third and first guide rail assemblies to engage or disengage synchronously with corresponding engagement structures via a first transmission member. A locking motor is provided on the second guide rail assembly, and the locking motor is adapted to drive the locking element on the second guide rail assembly to engage or disengage with corresponding engagement structures.

[0021] In one embodiment, a drive motor is provided on one of the third guide rail assembly and the first guide rail assembly, and the drive motor drives the moving rail of the third guide rail assembly and the moving rail of the first guide rail assembly to slide synchronously in a first direction via a second transmission member. A drive motor is provided on the second guide rail assembly, and the drive motor is adapted to drive the moving rail of the second guide rail assembly to slide in the first direction.

[0022] In one embodiment, the connecting pin is spaced apart from the circumferential wall of the receiving space.

[0023] The beneficial effects of this application are as follows: According to the technical solution of this application, the seat assembly is mounted on the vehicle floor via a guide rail system. The guide rail system has multiple guide rail assemblies, and these guide rail assemblies are respectively aligned with multiple strap outlets on the backrest. When the vehicle is impacted, these guide rail assemblies all bear the tension exerted on the seat assembly by the seat belt, and the tension borne by each guide rail assembly is relatively small, which makes these guide rail assemblies less prone to damage.

[0046] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] Figure 1 A vehicle 1 according to one embodiment of this application is schematically shown. Figure 1 As shown, vehicle 1 is equipped with a seating unit 101. The seating unit 101 is located near the trunk and serves as a rear seat. Vehicle 1 is also equipped with a front seat 102 located in front of the rear seat along a first direction D1 (the first direction is generally parallel to the length direction of the vehicle).

[0048] like Figure 2 As shown, the seat assembly 101 includes a seat assembly 2 and a guide rail system 3. The seat assembly 2 is mounted on the guide rail system 3 and can slide along a first direction D1 by means of the guide rail system 3 to facilitate adjustment of the position of the seat assembly 2 along the first direction D1. The guide rail system 3 will now be described.

[0049] The first embodiment of the guide rail system.

[0050] Figure 3 A first embodiment of the guide rail system is schematically shown. (As shown) Figure 3 As shown, a first embodiment of the guide rail system 3 includes three guide rail assemblies (i.e., a first guide rail assembly 301, a second guide rail assembly 302, and a third guide rail assembly 303) extending parallel to a first direction D1 and spaced apart along a second direction D2 (the second direction being generally parallel to the width direction of the vehicle). It should be noted that in this application, the first direction D1 and the second direction D2 are generally perpendicular. The third guide rail assembly 303 is positioned between the first guide rail assembly 301 and the second guide rail assembly 302 along the second direction D2. In one embodiment, the distance between the third guide rail assembly 303 and the first guide rail assembly 301 is less than the distance between the third guide rail assembly 303 and the second guide rail assembly 302.

[0051] like Figure 2As shown, the length direction of the seat assembly 2 is generally parallel to the second direction D2. The seat assembly 2 has a first end 201 and a second end 202 that are opposite to each other along the second direction D2, and also has a main body portion 203 located between the first end 201 and the second end 203. In one embodiment, the seat assembly 2 includes a seat body 21 and three adapter frames (i.e., a first adapter frame 221, a second adapter frame 222, and a third adapter frame 223).

[0052] like Figure 3 As shown, three adapter brackets are respectively mounted on three guide rail assemblies, and the seat body 21 is fixedly connected to the three adapter brackets. For example, as... Figure 5 As shown, the third adapter frame 223 is provided with multiple first mounting holes 211. Bolts (not shown in the figure) can be installed in these first mounting holes 211, and the seat body 21 can be fixedly connected to the third adapter frame 223 by the bolts. It should be noted that... Figure 3 The box in the image symbolically represents the seat body 21. Depending on the actual situation, the three adapter brackets may also be part of the seat body.

[0053] In one embodiment, each adapter includes two independent brackets. Each bracket is mounted on a corresponding guide rail assembly and is fixedly connected to the seat body. For example, as Figure 13 As shown, the two brackets 228 of the third adapter 223 are both mounted on the third guide rail assembly 303 and are fixedly connected to the seat body.

[0054] For example Figure 2 As shown, the seat body 21 has a backrest 23 extending along a second direction D2. The backrest 23 has a first edge 231 and a second edge 232 that are opposite to each other along the second direction D2, and also has a main body portion 233 located between the first edge 231 and the second edge 232. The first edge 231 corresponds to the first end 201 of the seat assembly 2, the second edge 232 corresponds to the second end 202 of the seat assembly 2, and the main body portion 233 of the backrest 23 corresponds to the main body portion 203 of the seat assembly 2. The seat body 21 has three seats. In this case, the seat assembly 2 also has three seat belts 204, and the backrest 23 is provided with three belt outlets 234 for the three seat belts 204. The three belt outlets 234 are spaced apart along the second direction D2. For example, the three belt outlets 234 are located at the first edge 231 of the backrest 23, the second edge 232 of the backrest 23, and the main body portion 233 of the backrest 23, respectively.

[0055] After the seat assembly 2 is installed onto the guide rail system 3, the first guide rail assembly 301 corresponds to the strap outlet at the first edge 231 of the backrest 23 along a third direction D3 (the third direction is generally parallel to the height direction of the vehicle) (e.g., the first guide rail assembly 301 is aligned with the corresponding strap outlet along the first direction D3), the second guide rail assembly 302 corresponds to the strap outlet at the second edge 232 of the backrest 23 along a third direction D3 (e.g., the second guide rail assembly 302 is aligned with the corresponding strap outlet along the first direction D3), and the third guide rail assembly 303 corresponds to the strap outlet at the main body 233 of the backrest 23 along a third direction D3 (e.g., the third guide rail assembly 303 is aligned with the corresponding strap outlet along the first direction D3). In the event of a vehicle impact, these seat belts 204 exert a pulling force on the seat assembly 2. Since the three guide rail assemblies correspond to the three belt outlets 234 on the backrest 23, each of the three guide rail assemblies bears the tension exerted by the three seat belts 204 on the seat assembly 2, and the tension borne by each guide rail assembly is relatively small, which makes these guide rail assemblies less prone to damage.

[0056] It should be understood that, depending on the actual situation, the guide rail system may also include four or more guide rail assemblies, which will not be elaborated here.

[0057] The three guide rail assemblies are similar. For simplicity, the following description will focus on the third guide rail assembly.

[0058] like Figure 4 As shown, the third guide rail assembly 303 includes a fixed rail 304 and a moving rail 305. The fixed rail 304 is, for example, fixedly mounted on the vehicle floor and extends along a first direction D1. The moving rail 305 is slidably engaged with the fixed rail 304. The third adapter frame 223 of the seat assembly 2 is connected to the moving rail 305 (e.g., Figure 5 (As shown). In this way, by sliding the moving rail 305 relative to the fixed rail 304 along the first direction D1, the seat body 21 (or seat assembly 2) can be slid along the first direction D1 and the position of the seat body 21 (or seat assembly 2) can be adjusted along the first direction D1.

[0059] For example Figure 4 As shown, a connecting structure 31 is provided on the fixed rail 304. For example, the connecting structure 31 includes a plurality of protrusions 311 formed on the fixed rail 304 and a plurality of locking windows 312 defined by these protrusions 311. For example, these protrusions 311 are arranged at intervals along a first direction D1, and the interval between adjacent protrusions 311 forms the locking window 312. In other words, these locking windows 312 are also arranged at intervals along the first direction D1.

[0060] A locking element 32 is provided on the moving rail 305. For example... Figure 6As shown, the locking member 32 includes a locking tooth seat 321 and locking teeth 322 extending from the locking tooth seat 321 toward the lock window 312. There are multiple locking teeth 322, arranged along a first direction D1. The locking member 32 is also movable relative to the moving rail 305 (or the fixed rail 304) along a third direction D3. When the locking teeth 322 engage within the lock window 312, the moving rail 305 cannot slide relative to the fixed rail 304 along the first direction D1, thus the third guide rail assembly 303 is in a locked state. When the first guide rail assembly 301, the second guide rail assembly 302, and the third guide rail assembly 303 are all in a locked state, the seat assembly 2 connected to the moving rail 305 cannot slide along the first direction D1. After the locking member 32 moves downward along the third direction D3, causing the locking teeth 322 to disengage from the lock window 312, the moving rail 305 can slide relative to the fixed rail 304 along the first direction D1, thus the third guide rail assembly 303 is in an unlocked state. When the first guide rail assembly 301, the second guide rail assembly 302, and the third guide rail assembly 303 are all in the unlocked state, the seat assembly 2 connected to the moving rail 305 can slide along the first direction D1. After adjusting the seat assembly 2 to the desired position along the first direction D1, the locking member 32 moves upward along the third direction D3, causing the locking teeth 322 to engage within the lock window 312. Thus, the first guide rail assembly 301, the second guide rail assembly 302, and the third guide rail assembly 303 all return to the locked state.

[0061] For example Figure 6 As shown, the moving rail 305 is constructed with a receiving space (not shown in the figure). Guide grooves 306, matching the locking teeth 322, are constructed on the side wall of the receiving space facing the fixed rail 304. For example, there are five locking teeth and five guide grooves. These guide grooves 306 generally extend in a strip shape along the third direction D3. The locking member 32 is movably disposed within the receiving space, and the locking teeth 322 extend from the receiving space toward the lock window 312 via the guide grooves 306. This prevents the locking member 32 from accidentally disengaging from the moving rail 305, which could cause malfunction of the third guide rail assembly 303.

[0062] like Figure 4 As shown, the guide rail 304 is provided with two rows of lock windows 312 (or engaging structures 31), the two rows of lock windows 312 are parallel along the first direction D1 and there is a gap 313 between the two rows of lock windows 312. Lock teeth 322 are matched with the two rows of lock windows 312. When the locking member 32 moves downward along the third direction D3, so that the lock teeth 322 enter the gap 313 and engage with the corresponding lock windows in the two rows of lock windows 312, the third guide rail assembly 303 is in the locked state. When the locking member 32 moves upward along the third direction D3, so that the lock teeth 322 leave the gap 313 and disengage from the corresponding lock windows in the two rows of lock windows 312, the third guide rail assembly 303 is in the unlocked state.

[0063] For example Figure 6As shown, the locking member 32 also includes two resilient reset members 323. For example, the reset members are springs or other suitable elastic elements. After the locking member 32 is installed into the receiving space, each reset member 323 is connected at both ends to the moving rail 305 and the locking tooth seat 321, respectively. Furthermore, the locking member 32 also includes a drive rod 324 connected to the locking tooth seat 321. For example, the drive rod 324 extends generally upward along a third direction D3 to the outside of the receiving space. The drive rod 324 and the reset members 323 are used to jointly drive the locking tooth seat 321 (and the locking teeth 322) to move along the third direction D3.

[0064] When the first guide rail assembly 301, the second guide rail assembly 302, and the third guide rail assembly 303 are all locked, the reset member 323 is not tensioned. When it is necessary to adjust the position of the seat assembly 2 along the first direction D1, the occupant can manually press the drive rod 324 downwards along the third direction D3 directly or indirectly, and the two reset members 323 are tensioned. The locking tooth seat 321 and the locking tooth 322 move downwards along the third direction D3 until the locking tooth 322 disengages from the lock window 312, so that the third guide rail assembly 303 is in the unlocked state. When the first guide rail assembly 301, the second guide rail assembly 302, and the third guide rail assembly 303 are all unlocked, the occupant can manually push the seat assembly 2 directly or indirectly along the first direction D1. After the seat assembly 2 moves to the desired position, the occupant releases the pressure applied to the drive rod 324, the two reset members 323 return to their original position and drive the locking tooth seat 321 and the locking tooth 322 to move upwards along the third direction D3. After the locking teeth 322 move to engage with the locking window 312, the third guide rail assembly 303 returns to the locked state. Once the first guide rail assembly 301, the second guide rail assembly 302, and the third guide rail assembly 303 have all returned to the locked state, the seat assembly 2 is stably held in the desired position. It should be understood that, depending on the actual situation, the locking element can also be located on the fixed rail, and correspondingly, the engagement structure can be located on the moving rail; this will not be elaborated further here.

[0065] In the guide rail system 3, each locking tooth 322 of the locking member 32 has a first width along the first direction D1. Each locking window 312 of the engagement structure 31 has a second width along the first direction D1. For the first guide rail assembly 301 and the second guide rail assembly 302, the first width and the second width are equal or substantially equal. However, for the third guide rail assembly 303, the first width is smaller than the second width. For example, the ratio of the first width to the second width is between 1.6 and 2. In a specific embodiment, the first width is approximately 5 mm and the second width is approximately 9 mm. In other words, when the third guide rail assembly 303 is in the locked state, the locking teeth 322 of the third guide rail assembly 303 can move along the first direction D1 within the corresponding locking window 312.

[0066] In some cases, when adjusting the position of the seat assembly 2 along the first direction D1, the first guide rail assembly 301 and the second guide rail assembly 302 may move asynchronously. For example... Figure 7 As shown, after the first guide rail assembly 301 and the third guide rail assembly 303 of the guide rail system 3 are in the locked state, the second guide rail assembly 302 does not enter the locked state. Figure 8 As shown, in the first guide rail assembly 301 and the third guide rail assembly 303, the locking teeth 322 engage with the corresponding lock windows 312. However, in the second guide rail assembly 302, the locking teeth 322 do not engage with the corresponding lock windows 312. In this case, the occupant can push the seat assembly 2 generally along the first direction D1. The difference between the first width of the locking teeth 322 of the third guide rail assembly 303 and the second width of the corresponding lock window 312 provides the seat assembly 2 with movement space along the first direction D1, allowing the second end 202 of the seat assembly 2 to move an appropriate distance along the first direction D1. Driven by the second end 202 of the seat assembly 2, the locking teeth 322 of the second guide rail assembly 302 can move along the first direction D1 and engage with the corresponding lock windows 312, causing the second guide rail assembly 302 to enter a locked state (e.g., Figure 9 and Figure 10 (As shown).

[0067] Reference Figure 5 and Figure 6 The moving rail 305 of the third guide rail assembly 303 is provided with a connecting seat 33. For example, a connecting seat 33 is provided at both ends of the moving rail 305 along the first direction D1. The two connecting seats have the same structure, and for simplicity, only one connecting seat will be described below.

[0068] Reference Figure 11a and Figure 12a The connecting seat 33 defines a receiving space 335. For example, the circumferential wall of the receiving space 335 includes a first arm 331, a second arm 332, a first connecting rod 333, and a second connecting rod 334. The first arm 331 and the second arm 332 are opposite to and spaced apart from each other along a first direction D1. The first connecting rod 333 and the second connecting rod 334 connect between the first arm 331 and the second arm 332 and are generally spaced apart from each other along a third direction D3. Thus, the first arm 331, the second arm 332, the first connecting rod 333, and the second connecting rod 334 collectively define the receiving space 335. In one embodiment, the first arm 331 and the second arm 332 extend generally upward toward the seat assembly 2 along a third direction D3. The first connecting rod 333 and the second connecting rod 334 extend generally along the first direction D1. It should be understood that the first arm and the second arm may also extend in other directions, which are not limited here.

[0069] For example Figure 11aAs shown, connecting holes 338 are constructed on both the first arm 331 and the second arm 332. The second connecting rod 334 is implemented as a bolt. The bolt is installed in the two connecting holes 338, thereby fixing it to the first arm 331 and the second arm 332. This facilitates the installation and removal of the connecting pin 225 (described below) on the seat assembly 2 within the receiving space 335 as needed.

[0070] Reference Figure 6 and Figure 12a The third adapter 223 is provided with connecting pins 225 corresponding to the connecting seat 33 (for example, connecting pins 225 are provided at both ends of the third adapter 223 along the first direction D1). Depending on the actual situation, the connecting pins are detachably mounted on the third adapter. The connecting pins can be implemented as bolts (e.g., stepped bolts) or wires (e.g., wires with a diameter of approximately 8mm to 12mm). Of course, the connecting pins can also be in other forms, which will not be elaborated here. In one embodiment, such as... Figure 6 As shown, the third adapter 223 is constructed with two connecting arms 229 extending toward the connecting seat 33. The two connecting arms 229 are spaced apart and each has a second mounting hole 212. When assembling the third bogie 223 with the moving rail 305, as... Figure 5 As shown, the connector 33 is positioned between the two connector arms 229, and the receiving space 335 is aligned with the two second mounting holes 212. The connecting pin 225 extends generally along the second direction D2 through the receiving space 335 and the two second mounting holes 212, thereby connecting the third adapter 223 to the moving rail 305.

[0071] It should be noted that the connecting pin 225 and the connecting seat 33 will not or substantially not move relative to each other, and thus the third adapter 223 and the moving rail 305 will also not or substantially not move relative to each other. For example, the connecting pin 225 is clamped between the first connecting rod 333 and the second connecting rod 334. In one embodiment, the connecting pin abuts against the first and second connecting rods. Thus, the connecting pin 225 is prevented from moving relative to the connecting seat 33 generally along a third direction D3. When the connecting pin 225 is subjected to a driving force along a first direction D1, the first connecting rod 333 and the second connecting rod 334 exert resistance on the connecting pin 225 opposite to the driving force and prevent the connecting pin 225 from moving relative to the connecting seat 33 along the first direction D1.

[0072] like Figure 12aAs shown, a first elastic pad 336 is provided between the connecting pin 225 and the first connecting rod 333 of the connecting seat 33. For example, the first elastic pad is an elastic rubber pad and has two connecting legs. The first connecting rod has two connecting notches corresponding to the two connecting legs. By engaging the two connecting legs into the two connecting notches, the first elastic pad is stably mounted on the first connecting rod. The connecting pin 225 is in close contact with the first elastic pad 336 and abuts against the second connecting rod 334 of the connecting seat 33. Thus, when the connecting pin 225 is subjected to a driving force along the first direction D1, the first elastic pad 336 and the second connecting rod 334 exert resistance on the connecting pin 225 opposite to the driving force, preventing the connecting pin 225 from moving relative to the connecting seat 33 along the first direction D1.

[0073] Reference Figure 12b and Figure 12c A second elastic pad 337 is provided between the connecting pin 225 and the second connecting rod 334 of the connecting seat 33. For example, the second elastic pad is also an elastic rubber pad. Figure 12b As shown, an elastic rubber layer is wrapped around the circumferential surface of the connecting pin 225, forming the second elastic pad described herein. Figure 12c As shown, an elastic rubber layer is wrapped around the circumferential surface of the second connecting rod 334 (or the bolt serving as the second connecting rod 334), forming the second elastic pad described herein. The connecting pin 225 is in close contact with the second elastic pad 337 and abuts against the first connecting rod 333 of the connecting seat 33. Thus, the second elastic pad 337 and the first connecting rod 333 also prevent the connecting pin 225 from moving relative to the connecting seat 33 along the first direction D1 and the third direction D3.

[0074] It should be understood that, depending on the actual situation, the first elastic pad and the second elastic pad mentioned above can coexist between the connecting pin and the connecting seat, which will not be elaborated here.

[0075] like Figure 11bAs shown, the connecting seat 33 can also be integrally formed. For example, the connecting seat 33 is formed as a through hole 339 defining a receiving space 335, and the axial direction of the through hole 339 is generally parallel to the second direction D2. In this way, the connecting seat eliminates the need for a second connecting rod, reducing the manufacturing difficulty of the moving rail. When assembling the third bogie 223 with the moving rail 305, the connecting seat 33 is also disposed between the two connecting arms 229 of the third bogie 223, and the receiving space 335 (or through hole 339) is aligned with the second mounting holes 212 on the two connecting arms 229. The connecting pin 225 extends generally along the second direction D2 through the receiving space 335 and the two second mounting holes 212, thereby connecting the third adapter 223 with the moving rail 305. It should be noted that the connecting pin 225 is still held by the corresponding side wall of the through hole 329 along the third third direction D3, and is spaced apart from the corresponding side wall of the through hole 329 along the first direction D1. For example, the cross-section of the connecting pin or the cross-section of the through hole is elliptical, which will not be elaborated here.

[0076] In one embodiment, the moving rail of the first guide rail assembly 301 is rigidly connected to the first adapter frame 221, and the moving rail of the second guide rail assembly 302 is rigidly connected to the second adapter frame 222. Figure 14 The structure of the rigid connection between the moving rail of the first guide rail assembly and the first adapter frame is schematically shown. At each end of the moving rail 305 along the first direction D1, a first connecting plate 307 is constructed at an appropriate angle relative to a third direction D3. The first adapter frame 221 is constructed with a second connecting plate 227 that matches the first connecting plate 307. The first connecting plate 307 and the second connecting plate 227 are fitted together and connected using connecting bolts 226, thereby achieving a rigid connection between the first adapter frame 221 and the moving rail 305. The structure of the rigid connection between the moving rail of the second guide rail assembly and the second adapter frame is similar. Figure 14 The rigid connection shown has the same structure, so it will not be described again here.

[0077] When the three guide rail assemblies are locked, the three adapter frames are prevented from moving along the first direction D1 by the three moving rails, and the seat assembly 2 cannot move along the first direction D1. When the three guide rail assemblies are unlocked, pushing the seat assembly 2 along the first direction D1 allows the three adapter frames to move along the first direction D1 via the three moving rails, and the seat assembly 2 can then move along the first direction D1.

[0078] It should also be noted that after the seat assembly 2 and the guide rail system 3 are assembled together, the first adapter 221 is rigidly connected to the moving rail of the first guide rail assembly 301, and the second adapter 222 is also rigidly connected to the moving rail of the second guide rail assembly 302 (as described above). In this case, the position of the connecting pin 225 on the third adapter 223 within the receiving space 335 on the moving rail of the third guide rail assembly 303 and / or the angle of the connecting pin 225 can be adjusted as needed along the first direction D1, because the connecting pin 225 is spaced apart from the first arm 331 and the second arm 332 along the first direction D1 (e.g., Figure 12a , Figure 12b and Figure 12c (As shown). In this way, not only can the third adapter 223 and the third guide rail assembly 303 be stably connected together, but the moving rail of the third guide rail assembly 303 can also be prevented from being stressed or even deformed. When adjusting the position of the seat assembly 2 along the first direction D1, the moving rails of the first guide rail assembly 301, the second guide rail assembly 302, and the third guide rail assembly 303 can all slide smoothly along the first direction D1, and the seat assembly 2 can also slide smoothly along the first direction D1.

[0079] A second embodiment of the guide rail system.

[0080] The second embodiment of the guide rail system is similar to the first embodiment of the guide rail system; the differences between the two are described below.

[0081] like Figure 15 As shown, a connecting seat 33 is provided on the moving rail of the third guide rail assembly 303, and a connecting pin 225 is provided on the third adapter frame 223. The connecting pin 225 is connected to the connecting seat 33 (that is, the connection method between the third adapter frame and the moving rail of the third guide rail assembly is the same as that in the first embodiment of the guide rail system). The connection method between the first adapter frame 221 and the moving rail of the first guide rail assembly 301, and the connection method between the second adapter frame 222 and the moving rail of the second guide rail assembly 302 are also the same, and will not be described again here.

[0082] With all three guide rail assemblies locked, the three connecting pins are prevented from moving along the first direction D1 (as described in the first embodiment of the guide rail system). Thus, the position of the seat assembly 2 remains fixed or substantially fixed.

[0083] When the three guide rail assemblies are in the unlocked state, the three adapter frames can move along the first direction D1 via the three moving rails, and the seat assembly 2 can also move along the first direction D1.

[0084] As described above, each connecting pin is spaced apart from the first and second arms of the connecting seat along a first direction D1 within its corresponding receiving space. In the event of a vehicle collision and when the seat body is pulled by the seatbelt, the connecting pin can move generally along the first direction D1 within the receiving space. The circumferential walls of the receiving space limit the range of motion of the connecting pin to a small area, thus minimizing the movement of the seat body. This helps maintain a safe posture for the occupant seated in the seat body, improving occupant safety.

[0085] The third embodiment of the guide rail system.

[0086] The third embodiment of the guide rail system is similar to the first embodiment; only the differences between the two are described below. (Refer to...) Figure 16 and Figure 17 Each guide rail assembly is equipped with a locking motor 341 and a drive motor 342.

[0087] Each locking motor 341 is used to drive the corresponding locking member 32 to engage or disengage with the corresponding engagement structure 31. For example, each locking motor 341 is connected to the drive rod 324 of the corresponding locking member 32. In this way, the locking motor 341 can drive the locking member 32 to move along a third direction D3 to engage or disengage with the corresponding engagement structure 31. It should be noted that in this case, the locking member may not have a reset member.

[0088] Each drive motor 342 is used to drive the corresponding moving rail to slide along the first direction D1, which facilitates the occupant to adjust the position of the seat assembly 2 along the first direction D1. The drive motors are well known to those skilled in the art and will not be described in detail here.

[0089] like Figure 18 As shown, in the third guide rail assembly 303 of the third embodiment of the guide rail system, the connecting pin 225 extends through the receiving space 335 defined by the connecting seat 33 on the moving rail 305 and is spaced apart from the circumferential walls of the receiving space 335 (i.e., the first arm 331, the second arm 332, the first connecting rod 333, and the second connecting rod 334).

[0090] When adjusting the position of the seat assembly 2 along the first direction D1, the drive motors on the three guide rail assemblies drive the moving rails of the three guide rail assemblies to move approximately synchronously along the first direction D1. Driven by the moving rails of the first and second guide rail assemblies, the seat assembly and the moving rail of the third guide rail assembly move synchronously along the first direction D1. The connecting seat on the moving rail of the third guide rail assembly and the connecting pin of the third adapter frame of the seat assembly also move approximately synchronously, keeping the connecting pin spaced apart from the circumferential wall of the receiving space.

[0091] In the event of a vehicle collision, the seatbelt applies tension to the seat body, causing it to move. The connecting pin moves accordingly within the receiving space as the seat body moves. The circumferential walls of the receiving space limit the range of motion of the connecting pin to a small area, thus minimizing the overall movement of the seat body. This helps maintain a safe posture for the occupant, improving occupant safety.

[0092] It should be understood that, depending on the actual situation, the connecting pin can also abut against the first connecting rod and the second connecting rod, which will not be elaborated here.

[0093] The fourth embodiment of the guide rail system.

[0094] The fourth embodiment of the guide rail system is similar to the third embodiment of the guide rail system; the differences between the two are described below.

[0095] Reference Figure 19 and Figure 20 The distance between the third guide rail assembly 303 and the first guide rail assembly 301 is less than the distance between the third guide rail assembly 303 and the second guide rail assembly 302. A locking motor 341 is provided on the first guide rail assembly 301, and a drive motor 342 is provided on the third guide rail assembly 303. The locking motor 341 is connected to the locking element on the first guide rail assembly 301 and is also connected to the locking element on the third guide rail assembly 303 via a first transmission member 343. Thus, the locking motor 341 on the first guide rail assembly 301 can drive the locking elements on both the first and third guide rail assemblies to move synchronously. The drive motor 342 is connected to the moving rail of the third guide rail assembly 303 and is also connected to the moving rail of the first guide rail assembly 301 via a second transmission member 344. Thus, the drive motor 342 on the third guide rail assembly 303 can drive both the moving rail of the first and third guide rail assemblies to move synchronously.

[0096] The second guide rail assembly 302 is also equipped with a locking motor 341 and a drive motor 342. The locking motor 341 drives the locking element on the second guide rail assembly 302 to move, and the drive motor 342 drives the moving rail of the second guide rail assembly 302 to move.

[0097] In this way, the guide rail system uses only two locking motors and two drive motors, which helps to reduce the cost of the seat assembly.

[0098] In addition, the distance between the third guide rail assembly 303 and the first guide rail assembly 301 is small, which reduces the length of the first transmission member 343 and the second transmission member 344, thereby reducing the torque attenuation of the first transmission member 343 and the second transmission member 344 during the transmission process. This helps to make the locking members on the third guide rail assembly 303 and the locking members on the first guide rail assembly 301 move synchronously, and also makes the moving rail of the third guide rail assembly 303 and the moving rail of the first guide rail assembly 301 move synchronously.

[0099] The fifth embodiment of the guide rail system.

[0100] The fifth embodiment of the guide rail system is similar to the third embodiment of the guide rail system; the differences between the two are described below.

[0101] In the fifth embodiment of the guide rail system, each guide rail assembly does not have locking elements or engagement structures, but each guide rail assembly is equipped with a drive motor with a locking function, which is connected to the corresponding moving rail. This type of drive motor is well known to those skilled in the art and will not be described in detail here. When it is necessary to adjust the position of the seat assembly along the first direction D1, the drive motor drives the corresponding moving rail to move along the first direction D1, and the seat assembly moves along the first direction D1. When the seat assembly moves to the desired position along the first direction D1, the drive motor stops rotating and locks. In this way, the moving rail cannot move along the first direction D1, and the seat assembly remains in the desired position.
