[0002] As a very important passive safety device in an automobile, a safety belt can effectively protect the life safety of a person in the vehicle when the vehicle collides or brakes in an emergency. With the development of the automobile industry, users have higher and higher requirements for the comfort of automobile seats.

[0003] The position of a traditional safety belt is usually not adjustable, especially for rear seats. Due to the vehicle type, interior design, and other reasons, the safety belts of many vehicles are led out from behind the seats. When a passenger sits in the rear row, due to different body types of passengers, the safety belt at the same position cannot meet the best comfort and the highest safety of all passengers. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the present application provides a safety belt adjusting device and a vehicle to solve the problem that the safety belt of the rear seat of the vehicle in the prior art is not adjustable.

[0005] In order to achieve the above purpose, the present application provides the following technical solutions:

[0006] A safety belt adjusting device comprises:

[0007] A lower seat assembly capable of being fixed on a seat, wherein the lower seat assembly has a clamping groove extending along a first horizontal direction, and the clamping groove has multiple clamping positions;

[0008] An upper seat assembly connected to the lower seat assembly in sliding mode along the first horizontal direction, and the upper seat assembly has a guide ring for a safety belt to pass through;

[0009] A clamping structure comprising a sliding member and an elastic member, wherein the sliding member is connected to the upper seat assembly in sliding mode along a vertical direction, and the elastic member applies a compression force to the sliding member along the vertical direction to compress the clamping groove;

[0010] When the upper seat assembly is subjected to a pushing and pulling force applied by a user, the sliding member can overcome the compression force and slide along the clamping groove to make the upper seat assembly slide along the lower seat assembly. When the pushing and pulling force is removed, the sliding member can be clamped with the clamping groove at the clamping position to fix the upper seat assembly relative to the lower seat assembly.

[0011] Optionally, the sliding member comprises:

[0012] A main body;

[0013] a plug body connected with the main body and extending along the vertical direction, the plug body being slidably plugged with the upper seat assembly;

[0014] a latch connected with the main body and extending along a second horizontal direction, the second horizontal direction being perpendicular to the first horizontal direction, the latch being slidably connected with the latch slot and being latched with the latch slot at the latching position.

[0015] Optionally, the main body comprises:

[0016] a horizontal portion spanning the latch slot and being above the latch slot along the second horizontal direction;

[0017] vertical portions connected with both ends of the horizontal portion and being on both sides of the latch slot;

[0018] wherein the horizontal portion and the vertical portions enclose a semi-enclosed space, the latch being in the semi-enclosed space and connected with the vertical portions.

[0019] Optionally, the elastic member is a compression spring and exerts pressure on the upper seat assembly and the sliding member respectively.

[0020] Optionally, the latch slot comprises a plurality of concave portions and a plurality of convex portions, the concave portion being between two adjacent convex portions, both ends of the latch slot being the concave portions, and any of the concave portions being the latching position.

[0021] Optionally, the top end of the convex portion is a flat surface or an arc surface.

[0022] Optionally, the distance between two adjacent concave portions is 15 mm; and / or,

[0023] the span of the latch slot in the first horizontal direction is 45 mm.

[0024] Optionally, the lower seat assembly comprises:

[0025] a lower seat body slidably connected with the upper seat assembly;

[0026] a track body connected with the lower seat body and extending along the first horizontal direction, the track body forming the latch slot.

[0027] Optionally, the guide ring is provided with a notch.

[0028] A vehicle, the rear seat of the vehicle being provided with the safety belt adjusting device according to any one of the above.

[0029] The safety belt adjusting device provided by the application comprises a lower seat assembly, an upper seat assembly and a locking structure. The lower seat assembly can be fixed on a seat. The lower seat assembly has a clamping groove extending along a first horizontal direction. The clamping groove has multiple locking positions. The upper seat assembly is connected with the lower seat assembly in sliding mode along the first horizontal direction. The upper seat assembly has a guide ring for the safety belt to pass through. The locking structure comprises a sliding member and an elastic member. The sliding member is connected with the upper seat assembly in sliding mode along a vertical direction. The elastic member applies a pressing force to the sliding member along the vertical direction to press the clamping groove. When the upper seat assembly is subjected to a pushing and pulling force applied by a user, the sliding member can overcome the pressing force and slide along the clamping groove to make the upper seat assembly slide along the lower seat assembly. When the pushing and pulling force is removed, the sliding member is locked with the clamping groove at the locking position to fix the upper seat assembly relative to the lower seat assembly. In this way, the upper seat assembly and the lower seat assembly have a position adjusting relationship. The triggering condition of the adjustment is the left and right pushing and pulling force applied by the user. When the user does not perform any operation, the elastic member presses the sliding member in the locking structure to make the sliding member be locked at the locking position, that is, the relative position between the upper seat assembly and the lower seat assembly is fixed. When the pushing and pulling force applied by the user reaches a certain degree, the pushing and pulling force provides a force to the sliding member to overcome the pressing force of the elastic member and make the sliding member slide along the clamping groove. During the sliding process of the upper seat assembly, the sliding member moves in the vertical direction and the elastic member deforms. When the upper seat assembly slides to the required position, the pushing and pulling force is removed. At the same time, the upper seat assembly is affected by the locking structure to fix the relative position between the upper seat assembly and the lower seat assembly again. When the safety belt adjusting device provided by the application is applied to the rear seat of a vehicle, the safety belt of the rear seat passes through the guide ring. Since the upper seat assembly can slide along the lower seat assembly and be locked and fixed, the safety belt is driven by the upper seat assembly to complete the position adjustment, thereby solving the problem that the safety belt of the rear seat of the vehicle cannot be adjusted in the prior art.

[0046] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0047] The applicant finds that in the related art, after the rear seat safety belt is buckled by the occupant after sitting, due to the difference in body size, the following problems may occur for some occupants: the safety belt is too close to the neck, the edge of the safety belt repeatedly presses the human body, giving the occupant the feeling of being choked, and the experience is not good; or the safety belt is too far from the shoulder, the safety belt is at the edge of the human shoulder, and the shoulder may slip, so the occupant cannot be fixed stably, and the safety is reduced.

[0048] As Figures 1-6As shown, the embodiment of the present application provides a safety belt adjusting device applied to a rear seat of a vehicle, which comprises a lower seat assembly 100, an upper seat assembly 200 and a locking structure 300; the lower seat assembly 100 is fixed on the seat, and the lower seat assembly 100 has a clamping groove 121 extending along a first horizontal direction, and the clamping groove 121 has multiple locking positions; the upper seat assembly 200 is slidingly connected with the lower seat assembly 100 along the first horizontal direction, and the upper seat assembly 200 has a guide ring 210 for the safety belt to pass through; the locking structure 300 comprises a sliding piece 310 and an elastic piece 320, the sliding piece 310 is slidingly connected with the upper seat assembly 200 along a vertical direction, and the elastic piece 320 applies a pressing force to the sliding piece 310 along the vertical direction to press the clamping groove 121; when the upper seat assembly 200 is subjected to a pushing and pulling force applied by a user, the sliding piece 310 can overcome the pressing force and slide along the clamping groove 121 to make the upper seat assembly 200 slide along the lower seat assembly 100; when the pushing and pulling force is removed, the sliding piece 310 can be clamped with the clamping groove 121 at the locking position to fix the upper seat assembly 200 relative to the lower seat assembly 100. The first horizontal direction is the transverse direction of the rear seat.

[0049] In this way, the upper seat assembly 200 and the lower seat assembly 100 have a position adjusting relationship, and the triggering condition of the adjustment is the left and right pushing and pulling force applied by the user; when the user does not perform any operation, the elastic piece 320 in the locking structure 300 presses the sliding piece 310 to make the sliding piece 310 clamped at the locking position, that is, the relative position between the upper seat assembly 200 and the lower seat assembly 100 is fixed; when the pushing and pulling force applied by the user reaches a certain degree, the pushing and pulling force provides a force for the sliding piece 310 to overcome the pressing force of the elastic piece 320 and slide along the clamping groove 121; during the sliding process of the upper seat assembly 200, the sliding piece 310 moves in the vertical direction, and the elastic piece 320 deforms; when the upper seat assembly 200 slides to the required position and the pushing and pulling force is removed, the upper seat assembly 200 is again fixed relative to the lower seat assembly 100 under the influence of the locking structure 300; when the safety belt adjusting device provided by the present application is applied to the rear seat of the vehicle, the safety belt of the rear seat passes through the guide ring 210; since the upper seat assembly 200 can slide along the lower seat assembly 100 and be clamped and fixed, the safety belt completes the position adjustment under the driving of the upper seat assembly 200, thereby solving the problem that the safety belt of the rear seat of the vehicle cannot be adjusted in the prior art.

[0050] As to the connection between the upper seat assembly 200 and the sliding piece 310, specifically, the upper seat assembly 200 has a cavity with an opening facing the lower seat assembly 100, and the cavity can accommodate the sliding piece 310 and allow the sliding piece 310 to move up and down under force.

[0051] It should also be noted that the upper assembly 200 and the lower assembly 100 are in a limiting connection relationship. One of the upper assembly 200 and the lower assembly 100 is provided with a limiting groove extending along the first horizontal direction, and the other is provided with a limiting slide bar that mates with the limiting groove. The limiting groove and the limiting slide bar can only be assembled and connected from the first horizontal direction to form a limit in the vertical direction. Figure 2 An example is shown of a configuration in which the upper assembly 200 is provided with a limiting slide bar and the lower assembly 100 is provided with a limiting slide groove.

[0052] Regarding the structural design of the slider 310, in some specific embodiments, the slider 310 includes a main body 311, a connector 312, and a locking pin 313; the connector 312 is connected to the main body 311 and extends vertically, and the connector 312 is slidably inserted into the upper seat assembly 200; the locking pin 313 is connected to the main body 311 and extends along a second horizontal direction, which is perpendicular to the first horizontal direction, and the locking pin 313 can slide along the slot 121 and can form a locking engagement with the slot 121 at the locking position. Preferably, the connector 312 and the main body 311 are designed as an integral structure, which can be made of plastic, allowing for integral injection molding production; the locking pin 313 is made of a different material than the main body 311, and the locking pin 313 is assembled onto the main body 311, allowing the locking pin 313 to be made of a high-strength metal material, and facilitating the assembly of the slider 310. The elastic member 320 applies a clamping force to the main body 311 in a vertical direction, pressing against the slot 121.

[0053] With this configuration, different parts of the slider 310 are designed with different materials according to the different mating relationships between the slider 310 and other components. The parts that engage with the slot 121, namely the locking pin 313, are wear-resistant and have sufficient strength, while other parts can be designed to be as lightweight as possible.

[0054] It should be noted that there is no limit to the number of connectors 312. Figure 3 and Figure 4 The design of two connectors 312 is shown as an example.

[0055] In some other specific embodiments, some irregular designs of the main body 311 were obtained through exploration. The main body 311 includes a horizontal part 3111 and a vertical part 3112. The horizontal part 3111 spans the slot 121 along the second horizontal direction and is located above the slot 121. The vertical part 3112 is connected to both ends of the horizontal part 3111 and is located on both sides of the slot 121. The horizontal part 3111 and the vertical part 3112 enclose a semi-enclosed space, and the latch 313 is located in the semi-enclosed space and connected to the vertical part 3112.

[0056] With this configuration, the main body 311 is semi-enclosed in the shape of a door frame and is fastened to the slot 121. In this way, the main body 311 has a structure distributed on both sides of the slot 121, making it less likely for the sliding member 310 to tip over. This facilitates a smoother sliding of the sliding member 310 along the slot 121 and enhances the structural reliability.

[0057] In some alternative embodiments, the elastic element 320 is a compression spring with its two ends applying pressure to the upper seat assembly 200 and the slider 310, respectively. In conjunction with the foregoing embodiments, the elastic element 320 is located above the horizontal portion 3111 of the slider 310 and between the two inserts 312, applying a clamping force to the horizontal portion 3111. This design facilitates the assembly of the locking structure 300.

[0058] It should be noted that by selecting compression springs with different stiffness coefficients, the required pushing and pulling force of the push-pull upper seat assembly 200 can be adjusted. For example, it can be set to require a force of at least 10N to trigger the push-pull upper seat assembly 200. After testing and verification, it was found that under normal use, the pulling force of the seat belt on the guide ring 210 does not cause the seat belt to slide the upper seat assembly 200.

[0059] Of course, in addition to the above methods, it is also feasible to design the elastic element 320 as a tension spring and connect it between the sliding block and the lower seat assembly 100.

[0060] In some other specific embodiments, the slot 121 includes multiple recesses and multiple protrusions, with the recesses and protrusions spaced apart and continuously distributed. A recess is located between two adjacent protrusions, and both ends of the slot 121 are recesses, with any recess serving as a locking position. This ensures that the sliding limit position of the upper assembly 200 relative to the lower assembly 100 is also the locking and fixing position of the upper assembly 200, conforming to human usage habits.

[0061] Furthermore, in some preferred embodiments, the top of the protrusion is a flat or curved surface. This design facilitates the sliding block's passage through the protrusion, resulting in smoother user operation and a better user experience.

[0062] In some other specific embodiments, the distance between two adjacent recesses is 15 mm;

[0063] Alternatively, the span of the card slot 121 in the first horizontal direction is 45mm;

[0064] Alternatively, the distance between two adjacent recesses is 15mm, and the span of the slot 121 in the first horizontal direction is 45mm. In this design, the locking distance between the upper assembly 200 and the lower assembly 100 includes at least 0, 15mm, 30mm, and 45mm, where 0mm means the upper assembly 200 and the lower assembly 100 are directly opposite each other. This design, after testing and verification, can meet the adjustment needs of most users.

[0065] In some other specific embodiments, the lower seat assembly 100 includes a lower seat body 110 and a track body 120; the lower seat body 110 can be fixed to the rear seat, and the lower seat body 110 is slidably connected to the upper seat body of the upper seat assembly 200; the track body 120 is connected to the lower seat body 110 and extends along a first horizontal direction, and the track body 120 forms a slot 121. The lower seat body 110 can be designed as a lightweight and comfortable plastic material, and the track body 120 can be designed as a high-strength metal material, so that the track body 120 and the locking pin 313 of the sliding member 310 are made of the same material to meet wear resistance requirements.

[0066] In some other specific embodiments, the upper assembly 200 includes an upper body with a through hole to form a guide ring 210.

[0067] In some other preferred embodiments, the guide ring 210 is provided with a notch 2101 so that the seat belt can be inserted into the guide ring 210 through the notch 2101, which simplifies the assembly process and is also convenient for later disassembly and maintenance.

[0068] Based on the aforementioned seatbelt adjustment device, this application embodiment also provides a vehicle in which the rear seats are equipped with the aforementioned seatbelt adjustment device, that is, one seatbelt adjustment device is provided for each rear seatbelt. Figures 5-6 As shown. Since this vehicle has the aforementioned seatbelt adjustment device, the beneficial effects of the seatbelt adjustment device are described above and will not be repeated here.
