[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0021] As described in the background section, with the continuous increase in the popularity of private cars and the increasing frequency of long-distance inter-provincial travel, long-distance driving has become the norm for many drivers. On highways or national roads, drivers typically need to keep both hands on the steering wheel for several hours continuously to ensure the vehicle's stability and handling precision at high speeds. During this process, the driver's arms are in a continuously extended and slightly raised position, and multiple muscle groups in the shoulders and forearms must remain contracted for an extended period to maintain control of the steering wheel. According to human physiology, continuous isometric muscle contraction leads to restricted local blood circulation and lactic acid accumulation, causing muscle fiber fatigue, manifested as arm soreness and decreased grip strength. This can further lead to decreased attention and slowed reaction time, and in severe cases, directly affect driving safety and passenger comfort.

[0022] To address the aforementioned pain points, improvements have been made to automotive seat and interior structures in related technologies. For example, most models are equipped with a center armrest or door armrest in the driver's seat, and some high-end models also offer adjustable side armrests, allowing drivers to occasionally rest one arm on them during long journeys to temporarily relieve muscle tension. Specifically, the basic principle is to distribute the weight of the arm by providing a static support surface, allowing some muscle groups to rest.

[0023] However, the inventors of this application have discovered that such support devices are typically fixed in position and have a limited range of adjustment, failing to flexibly adapt to changes in driver height, seat position, and driving posture. Furthermore, they often only support part of the arm, leaving the rest of the arm suspended for extended periods while gripping the steering wheel, resulting in an uneven overall load-bearing effect. In addition, frequent use of armrests during driving can obstruct steering wheel rotation or restrict gear shifting and central control operations, thus posing potential safety hazards.

[0024] As can be seen, although the relevant technologies have alleviated arm fatigue to some extent, they still cannot systematically solve the problem of muscle load caused by holding the steering wheel for a long time: their support range is limited, their adaptability is insufficient, and their dynamic following is poor, making it difficult to continuously provide stable arm support without affecting normal operation.

[0025] To address the above problems, the inventors of this application propose a vehicle seat solution: Elastically retractable load-bearing straps 200 are provided on both sides of the car seat backrest 110. These straps 200 can adaptively adjust along their length and angle, providing continuous and stable support for the driver's arms and significantly reducing muscle load caused by prolonged steering wheel gripping. Furthermore, adjustable flexible supports can be added to the sides of the car seat body 100, forming a combined support with the load-bearing straps 200 through flexible contact surfaces. This allows the support position to change more flexibly according to the driver's body shape and seat posture, further dispersing local pressure. This structure ensures the driver's freedom of movement while maintaining normal steering wheel operation, and provides continuous and adjustable arm support, significantly reducing fatigue caused by prolonged shoulder and arm muscle contraction, thereby improving the safety and comfort of long-distance driving.

[0026] The following is in conjunction with the appendix Figures 1A-5 The embodiments of this application will be described in detail below.

[0027] In some embodiments, such as Figure 1A , Figure 1B and Figure 1C As shown, this application provides a vehicle seat, including: The seat body 100 includes a seat back 110 and a seat base 120; The load-bearing strap 200 is located on the side of the seat back 110 and includes a first end and a second end that are disposed opposite to each other along a first direction; the first end is movably connected to the side of the seat back 110 and is away from the seat base 120; the second end is close to the seat base 120 and is used for the user to wear to provide support and load reduction for their arms. The first direction is the direction extending along the height of the seat back 110.

[0028] For example, the vehicle seat is composed of a seat body 100 and a load-bearing belt 200 system. The seat body 100 (including a seat back 110 and a seat base 120) is the load-bearing base for the entire force transmission. Specifically, the seat back 110 provides the mounting surface for the load-bearing belt 200 (the side of the seat back 110), and can also have internally reserved reinforcement parts, 300 mounting slots, and wiring channels to ensure reliable connection with the vehicle frame and meet the human comfort requirements of the trim and padding layers. The seat base 120 bears the final load from the backrest, distributing the weight from the arms to the vehicle structure.

[0029] For example, the load-bearing strap 200 is arranged along the height direction (first direction) of the seat back 110, serving as the main support element. One end is movably connected to the side of the backrest near the upper end, and the other end is worn by the driver, thereby distributing the vertical load on the shoulder and arm muscles. The strap body needs to balance elasticity and tensile strength to adapt to different heights and sitting postures.

[0030] Specifically, the movable connection at the first end serves as a force-bearing and adjustment node. Optionally, it can employ a rotating hinge, a vertical guide rail lock, or a retractable spring shaft, and be reinforced by pre-embedded steel or aluminum alloy reinforcing plates, bolts, or rivets.

[0031] The second end contacts the driver's arm and can optionally be designed as a loop, buckle, or padded arm sleeve, and can be combined with a length adjustment and quick release mechanism to achieve comfortable wearing and emergency disengagement. All tension is transmitted to the seat back 110 and seat base 120 via the backrest reinforcement, ensuring a stable and reliable force path.

[0032] For example, the weight-reducing strap 200 can be a single strap arranged longitudinally, or a V-shaped (U-shaped) strap, a combination of two straps, etc., and can be made of high-strength polyester, aramid, or composite elastic webbing. It can also contain an elastic layer to control the elongation rate. The support part that contacts the arm can be fitted with memory foam or gel pads and covered with a removable and washable cover to improve comfort and durability.

[0033] For example, the embodiments of this application will be further described below in conjunction with the use of the load-reducing belt 200 in daily driving.

[0034] The load-bearing strap 200, when in use, achieves adaptive angle and height by being movably connected to the seat back 110, ensuring that the load-bearing strap 200 maintains a suitable support point regardless of seat adjustment or changes in driver body shape. Specifically, the first end of the load-bearing strap 200 is connected to the seat back 110 via a multi-degree-of-freedom movable connection (e.g., through the installation of a rotating hinge, vertical guide rail, or reel). Taking a rotating connection as an example, due to the rotating connection, the load-bearing strap 200 allows the strap to swing within a certain angle range around the hinge point on the side of the seat back 110. Regardless of whether the driver adjusts the backrest angle or makes a large forward or backward movement of the upper body, the strap can automatically adjust its angle accordingly, maintaining a pulling direction close to the natural vertical line of the arm, thus avoiding the generation of reverse torque.

[0035] Based on this, since the strap body of the weight relief belt 200 itself is elastic and can deform within a certain length range (e.g., 15-30cm), a vertical guide rail or a sliding locking mechanism with a roller can be set to allow the weight relief belt 200 to move up and down in the first direction of the seat back 110. Optionally, the user can quickly select between multiple positioning points by pressing the quick buckle, pulling the adjustment handle or the electric button, so that the support point can accurately match different heights and sitting postures.

[0036] In addition, the strap body of the weight-reducing belt 200 can be made of multi-layer composite webbing with built-in micro-elastic core material and fine-tooth ratchet or trapezoidal buckle, which can be finely tensioned after the driver wears it, so that it always maintains proper support when the backrest is adjusted, the body shape changes or the arm moves slightly up and down, and will not become loose or too tight due to changes in seat posture.

[0037] Furthermore, a seat support 500 (such as a foldable soft cushion on the backrest or a height-adjustable armrest) can be added in conjunction with the load-bearing belt 200. In this case, the seat support 500 and the load-bearing belt 200 form a "surface-belt" collaborative support. The seat support 500 provides a larger contact area to bear part of the vertical force on the underside of the arm, while the load-bearing belt 200 provides longitudinal suspension and tension. The installation points of both are independent but ergonomically calibrated: the support (seat support 500) is slightly lower than the support line of the belt (load-bearing belt 200). During use, the arm is first lightly placed on the support, and the load-bearing belt 200 uses slight pulling force to draw the arm inward against the support, achieving zoned force distribution—the support disperses local pressure, while the belt maintains overall stability. Optionally, the support may be equipped with a folding / rotating or sliding rail adjustment mechanism, which can be folded up when not in use to avoid interference; when in use, it can be finely adjusted in sync with the belt tension to ensure that there is no collision or constraint when the steering wheel is turned at large angles, shifting gears or operating the central control.

[0038] Through the above design, the vehicle seat in this embodiment can maintain a stable, comfortable and sustainable support effect during changes in the angle of the backrest (seat backrest 110), forward and backward movement of the seat, differences in driver body size, and even long-term driving. It smoothly transmits the weight of the arms to the seat frame and vehicle structure, significantly reducing the continuous load on the shoulder and arm muscles and delaying fatigue.

[0039] This embodiment provides a vehicle seat, including: a seat body 100, including a seat back 110 and a seat base 120; a weight-relief strap 200, located on the side of the seat back 110, including a first end and a second end disposed opposite to each other along a first direction; the first end is movably connected to the side of the seat back 110 away from the seat base 120, and the second end is for a user to wear to provide support and weight relief for their arms; wherein, the first direction is the direction of extension along the height of the seat back 110. This embodiment features a weight-relief belt 200 arranged along the height direction on the side of the seat back 110, with its first end movably connected to the end of the backrest away from the seat base 120. This allows the weight-relief belt 200 to adjust its position and swing accordingly in the height direction as the backrest angle or seat position changes, thus maintaining a natural fit with the arm regardless of the user's body shape or sitting posture. When the user places their arm on the second end of the weight-relief belt 200, the arm weight is transferred to the seat back 110 and base through the weight-relief belt 200, effectively supporting the shoulder and upper arm. This reduces the continuous stress and fatigue on the shoulder and arm muscles during long-distance driving, while improving overall comfort and durability without affecting steering wheel rotation, gear shifting, and central control operation.

[0040] In some embodiments, such as Figure 1A , Figure 1B and Figure 1C As shown, the side of the seat back 110 is provided with a mounting groove 300, the load-bearing belt 200 is located in the mounting groove 300, and is moved and positioned relative to the mounting groove 300 by the positioning component 400.

[0041] For example, the mounting groove 300 is located on the side of the seat back 110 and is used for the installation, guidance, and storage of the load-bearing strap 200. The mounting groove 300 can be firmly connected to the frame of the seat back 110 by means of an internally embedded steel reinforcing plate and by bolts or rivets, ensuring that the force path is directly transmitted to the seat base 120 and the vehicle body. Optionally, the edge of the mounting groove 300 is rounded and equipped with a wear-resistant bushing, which not only prevents the load-bearing strap 200 from being worn or cut during movement, but also takes into account the overall aesthetics and safety, while leaving an inspection channel between the surface and the groove body for easy maintenance and replacement in the future.

[0042] For example, the load-bearing strap 200 is arranged within the mounting groove 300 and is movable along the backrest height direction to accommodate different driver heights and sitting postures. The mounting groove 300 is equipped with a positioning component 400 that slides within it, allowing for smooth movement along the groove guide rail or slide and locking at the desired position. Specifically, the positioning method can employ mechanical multi-position locking, rack and pinion pawl, or lead screw fine-tuning, etc., to achieve continuous or graded adjustment of height and tension as needed.

[0043] For example, during driving, the driver places their arm on the support position at the second end of the belt, stretches or adjusts the belt to a suitable height, and then the positioning component 400 locks the position and transmits tension to the backrest frame and seat base 120, forming a complete force closed loop. Furthermore, the belt's length and tension can be finely adjusted according to the user's posture during use. Optionally, a soft support or removable and washable padding can be added to the outside of the belt to further distribute contact pressure and improve wearing comfort.

[0044] In this embodiment, by setting an installation groove 300 on the side of the seat back 110 and cooperating with the positioning component 400, the load-bearing belt 200 can be hidden and stably guided, so that the belt can move smoothly along the height direction during use and be reliably locked in the required position. This not only ensures a neat appearance, but also forms a complete force closed loop from the belt to the backrest frame, reducing the wear and tear caused by the force on the load-bearing belt 200.

[0045] In some embodiments, such as Figure 2A and Figure 2B As shown, the positioning component 400 includes a positioning button 410 and a slider 420. The slider 420 is located in the mounting groove 300 and is slidably connected to the mounting groove 300. The slider 420 has a first limiting position 421, and the mounting groove 300 is provided with a plurality of second limiting positions 310 in its length extension direction. When the positioning button 410 passes through the first end of the load-reducing band 200 and connects with the first limiting position 421, the slider 420 can drive the positioning button 410 and the load-reducing band 200 to move relative to the mounting groove 300; when the positioning button 410 passes through the first end of the load-reducing band 200 and connects with the first limiting position 421 and a second limiting position 310, the position of the load-reducing band 200 relative to the mounting groove 300 is fixed.

[0046] Exemplarily, the positioning component 400 is used to achieve smooth movement and reliable locking of the load-bearing belt 200 within the mounting groove 300. Specifically, it consists of a slider 420 and a positioning button 410, and cooperates with the mounting groove 300, which has multiple second limiting positions 310: the slider 420 provides guidance and force, driving the load-bearing belt 200 to move up and down within the groove; the positioning button 410 passes through the first end of the load-bearing belt 200 and cooperates with the first limiting position 421 of the slider 420, and can move with the slider 420 when unlocked; when the head of the positioning button 410 is simultaneously inserted into one of the second limiting positions 310 of the mounting groove 300, the three components are engaged and fixed, achieving final fixation of the belt at the selected height. This arrangement ensures smooth adjustment of the load-bearing belt 200 and provides high-strength discrete locking.

[0047] For example, the slider 420 slides along the guide structure (e.g., groove, rail) of the mounting groove 300. Its surface or edge may be provided with a low-friction bushing or self-lubricating layer to maintain a reasonable fit clearance of 0.1–0.5 mm, ensuring smooth movement without lateral sway. Furthermore, the first end of the load-reducing belt 200 may be provided with a reinforcing hole or a reinforcing ring. The positioning button 410 passes through this hole and is embedded in the first limiting position 421 (e.g., through hole, recess, or serration) on the slider 420, allowing the belt tension to be transmitted to the slider 420 via the positioning button 410.

[0048] The mounting groove 300 is provided with multiple second limiting positions 310 (such as through holes, recesses, or serrations) along its length, the size of which matches the head of the positioning button 410. During adjustment, the user presses (the positioning button 410 is equipped with a spring or self-resetting mechanism, which pops it out under its action) or pulls out the positioning button 410 to unlock it, and the slider 420 can move along the groove. When it moves to the target second limiting position 310, it is aligned and inserted to fix it, thus achieving final locking.

[0049] This embodiment uses a structure of "slider 420 + positioning button 410 + multiple limiting positions" to allow the load-bearing belt 200 to be smoothly adjusted and forcefully locked along the first direction. Users can quickly complete the adjustment and fixation with one hand, which is very suitable for driving scenarios. In addition, the positioning component 400 and the mounting slot 300 fit together tightly, resulting in a clean appearance and reducing the interference of exposed parts to the occupants, while ensuring a rigid load-bearing path and improving safety and durability.

[0050] In some embodiments, such as Figure 1A As shown, the second end of the weight-reducing belt 200 is provided with a magnetic component 220, and the corresponding area on the side of the seat back 110 is provided with a magnetic attraction position 111 that magnetically engages with it.

[0051] For example, the second end of the weight-reducing strap 200 is provided with a magnetic component 220, and a corresponding magnetic attraction position 111 is provided on the side of the seat back 110 to achieve quick fixing and release of the strap. Specifically, the magnetic component 220 at the second end of the weight-reducing strap 200 can quickly attract to the side of the backrest when the user's arm is removed from the strap, so that the strap is securely stored when not in use. The magnetic component 220 needs to have suitable attraction force, that is, it can be smoothly released when the user pulls the weight-reducing strap 200, and the surface of the component should be smooth or coated with plastic to avoid friction damage to the arm or the webbing.

[0052] Specifically, the magnetic component 220 is fixed to the second end of the weight-reducing strap 200 by sewing, clamping or molding to ensure that it does not come loose during use, and forms a controllable adsorption at the magnetic adsorption position 111 on the side of the backrest, which is convenient for arm support and also facilitates neat storage.

[0053] For example, the magnetic attachment point 111 on the side of the seat back 110 provides a reliable attachment point for the magnetic component 220, ensuring that the weight-reducing strap 200 is stably positioned on the side of the backrest. The material and magnetism of the magnetic attachment point 111 need to match the magnetic component 220 so that the attraction force is both strong enough and does not affect the user's operation. Optionally, it can also be coordinated with the internal structure and finish of the seat to maintain aesthetics and avoid interfering with the seat frame.

[0054] This embodiment avoids the use of mechanical locking devices by setting up mutually cooperating magnetic components 220 and magnetic attraction positions 111, reducing the overall structural complexity and weight, while ensuring that the load-bearing belt 200 is securely stored when not in use, thus avoiding interference with driving.

[0055] In some embodiments, such as Figure 3A and Figure 3B As shown, the vehicle seat also includes a seat support 500; the seat support 500 is located on the side of the seat back 110 near the seat base 120, and the seat support 500 is rotatably connected to the seat back 110 so that the seat support 500 has a use state and a storage state relative to the seat back 110. When the seat support 500 is in use, the orthographic projection of the seat support 500 on the side of the seat body 100 is perpendicular to the seat back 110; when the seat support 500 is in storage, the orthographic projection of the seat support 500 on the center plane is located within the orthographic projection of the seat back 110 on the center plane; the center plane is the center section of the seat body 100 along the first direction.

[0056] For example, the seat support 500 is located on the side of the seat back 110 near the seat base 120. Specifically, it can be connected to the backrest via a pivot or hinge to achieve a rotatable folding structure. In use, the support (seat support 500) forms a natural arm support surface, bearing the weight of the arm. The pivot transmits torque to the backrest frame and seat base 120, distributing shoulder and arm muscle load and improving driver comfort during long drives. Simultaneously, in the folded state, the support can rotate back to the side of the backrest, maintaining a neat backrest profile without interfering with the driver's entry / exit or seat adjustment.

[0057] For example, the support surface of the seat support 500 can be filled with foam and covered with fabric or leather to provide a soft and comfortable feel; the internal load-bearing frame uses metal or high-strength plastic to ensure that it does not deform when bearing the weight of the arm. In addition, the rotating connection can adopt single-axis rotation, bearing rotation, or hinge with limit baffle to ensure smooth and stable switching between the use state and the storage state of the support. At the same time, the position of the support can be controlled by spring return, friction locking, or locking limit structure to prevent the support from falling or shaking during vibration.

[0058] For example, the seat support 500 and the load-bearing strap 200 work together to form a rigid-flexible arm support system. In use, the support provides a fixed support surface, while the load-bearing strap 200 provides flexible support on one side, allowing the shoulder and arm load to be distributed more evenly. When the support is stowed, it does not interfere with the adjustment, magnetic fixation, or other operations of the load-bearing strap 200, ensuring the integrity of the seat's function and its aesthetic appearance.

[0059] This embodiment achieves dual functions of use and storage by setting a rotatable and foldable seat support 500 structure, providing stable and comfortable arm support while saving space and not affecting daily driving operations or seat appearance; in addition, it can be used in conjunction with the load-bearing belt 200 to form a rigid-flexible dual-end support system, further improving the comfort and shoulder and arm support effect of long-distance driving.

[0060] In some embodiments, such as Figure 4A and Figure 4B As shown, the vehicle seat also includes a seat support 500; the seat support 500 is located on the side of the seat base 120 and is rotatably connected to the seat base 120 so that the seat support 500 has a use state and a storage state relative to the seat base 120. When the seat support 500 is in use, the orthographic projection of the seat support 500 on the side of the seat body 100 is perpendicular to the seat base 120; when the seat support 500 is in storage, the orthographic projection of the seat support 500 on the center plane is located within the orthographic projection of the seat base 120 on the center plane; the center plane is the center section of the seat body 100 along the first direction.

[0061] The beneficial effects of this embodiment are the same as those of the seat support 500 in the above embodiment being disposed on the side of the seat back 110, and will not be repeated here.

[0062] In some embodiments, the vehicle seat further includes a displacement mechanism connected to the seat support 500 to control the relative movement of the seat support 500 along a first direction / length direction of the seat base 120.

[0063] For example, the displacement mechanism is located inside the seat back 110 or seat base 120 and is reliably connected to the seat support 500. It is used to adjust the position of the seat support 500 so that it can move along the height direction of the seat back 110 or the length direction of the seat base 120, thereby meeting the needs of different driver arm heights and fore-and-aft positions.

[0064] It should be noted that the displacement mechanism must be stable and reliable, capable of withstanding the weight of the support and arm, and ensuring that it does not slip unexpectedly under vehicle vibration conditions. The seat support 500 is then mounted on the side of the seat via the displacement mechanism. The connection method can be a sliding guide rail, roller, rack and pinion, lead screw, or electric push rod, etc., to ensure stability and prevent shaking during use, and to allow for manual or electric adjustment.

[0065] For example, the displacement mechanism can employ different methods such as linear guide rails + rollers, rack and pinion + gears, or lead screw drives, selecting a suitable solution in terms of smoothness, load-bearing capacity, and precision based on the vehicle model's positioning and functional requirements. Furthermore, the combination of the support's rotation and displacement functions ensures that the arm support is both height-adjustable and foldable for storage, while the adjustment range covers the natural arm placement area for drivers of different heights, maintaining the support surface angle consistent with the backrest curve, thus improving ergonomics. In addition, regarding load-bearing capacity and safety, all load-bearing structures are transmitted through the seat frame, the slide rails and guide surfaces are wear-resistant and corrosion-resistant, and the displacement mechanism layout does not interfere with the airbag or seatbelt system.

[0066] This embodiment achieves adjustable fore-and-aft position of arm support through the reasonable cooperation of displacement mechanism, seat support 500, and seat body 100; at the same time, it can be combined with the synergistic effect of rotating and storing seat support 500 and freely adjusting load-bearing belt 200 to form a support system that combines flexibility and rigidity, thereby improving the comfort of long-distance driving, reducing shoulder and arm fatigue, and ensuring that daily driving operation is not affected. The structure is safe and reliable, and the operation is smooth and convenient.

[0067] In some embodiments, such as Figure 5 As shown, the load-bearing belt 200 includes two telescopic belts extending from a first end to a second end, the two telescopic belts converging at the second end to form a support portion; or, The load-bearing belt 200 includes a telescopic belt body, the two ends of which meet and are fixed at the first end, so that the telescopic belt body forms a support portion at the second end.

[0068] For example, the load-bearing strap 200 is used to provide flexible support for the driver's arm, absorbing the weight of the arm through the support portion and distributing the load on the shoulder and arm muscles. Optionally, depending on the design, the load-bearing strap 200 can be in the form of two elastic straps converging or a single elastic strap intersecting: the two straps converge at the support portion to form a flexible ring structure, which can evenly distribute pressure and adapt to different arm sizes; the single strap intersecting to form a ring support portion can be easily slipped onto the arm or support, ensuring convenient wearing and flexible support effect.

[0069] The first end of the weight-reducing strap 200 is fixed to the connection point of the slider 420 / positioning component 400 by means of perforation, stitching, or buckle, so that it moves synchronously with the height or angle adjustment to ensure stable support. The support part of the second end is free to move, allowing the user to wear the armband, and can be combined with the seat support 500 to achieve the cooperation of flexible and rigid support.

[0070] In addition, in terms of structural design, the weight-reducing belt 200 must ensure that the belt body does not twist or knot during adjustment, and that the supporting part conforms to the natural shape of the arm. If necessary, soft pads, silicone layers or fabric coverings can be added to improve comfort and prevent slippage.

[0071] For example, the junctions of the double-stripe joints and the single-stripe intersections require reinforcement. Optionally, this can be achieved through stitching, heat fusion, or molding to ensure they do not detach under long-term tensile use. The material of the weight-reducing strap 200 can be elastic webbing, nylon webbing, polyester fiber, or elastic composite material, taking into account comfort, wear resistance, tensile strength, and environmental adaptability. The support portion can be designed in a ring or U-shape to conform to the natural curve of the arm and distribute pressure, achieving flexible support.

[0072] This embodiment, through the flexible support design of the load-bearing belt 200, can work in conjunction with the seat support 500, slider 420 and other structures to form an adjustable arm support system that is height and angle adaptive, so as to distribute arm pressure, reduce shoulder and arm fatigue, improve the comfort of long-distance driving, and at the same time ensure the flexibility and safety of arm operation. The structure is reliable and easy to operate.

[0073] In some embodiments, such as Figure 5 As shown, the support portion of the telescopic belt is provided with a support member 210 of an auxiliary support arm, and the support member 210 is a soft pad or a buffer pad.

[0074] For example, the support portion of the telescopic belt serves as the main contact area between the load-bearing belt 200 and the driver's arm, bearing the weight of the arm and transferring the load to the positioning mechanism and even the seat body 100. Specifically, the design of the support portion needs to balance flexibility and support force to ensure that it does not deform excessively or slip when the arm is under load, thus ensuring the stability and comfort of arm support. To this end, an auxiliary arm support member 210 needs to be added to the support portion to further distribute shoulder and arm pressure and enhance user comfort.

[0075] Optionally, the support member 210 may be made of elastic materials such as foam, silicone or EVA, with a smooth and soft surface, and must be firmly connected to the telescopic belt to ensure that it does not shift under tension, load and vehicle vibration conditions.

[0076] For example, the connection between the support member 210 and the support part of the telescopic belt can be achieved by sewing, heat fusion, bonding or bagging to ensure that it does not fall off under load or tension, while keeping the support surface flat.

[0077] For example, the support member 210 can be designed as a long strip or an oval shape, covering the natural contact area of ​​the arm, and its thickness and hardness need to balance support and comfort. Furthermore, the surface of the support member 210 can be covered with fabric or leather to improve tactile feel and abrasion resistance. Its fixing method can be selected according to the material and usage requirements, such as sewing, heat fusion, or a pouch, to ensure that the support member 210 is secure and reliable during use, while also facilitating cleaning or replacement.

[0078] This embodiment, through the design of setting the support member 210 in the support part of the telescopic belt, ensures that the weight of the arm is evenly distributed by the synergistic effect of the telescopic belt and the support member 210, reduces local pressure points, achieves flexible, comfortable and stable arm support, reduces fatigue during long-distance driving, and adapts to different arm sizes and body shapes of drivers, ensuring operational flexibility and safety.
