Description
TECHNICAL FIELD
[0001] Embodiments of the present disclosure relate to the technical field of safety belt protection pad, in particular, to a safety belt anti-choking abdominal protection pad. BACKGROUND
[0002] When traveling, safety belts are undoubtedly the key line of defense to protect our lives. It is like a loyal guard, which is ready to fix us firmly on the seat in the event of an emergency during vehicle travel, greatly reducing the harm caused to the human body in the accident. However, this "guard" sometimes also brings some troubles.
[0003] When emergency braking occurs, the vehicle will quickly stop from high-speed driving in a very short time. At this time, due to inertia, the body of the person in the vehicle will suddenly rush forward, and the safety belt will generate a strong pulling force in order to constrain the body. This pulling force will act on the chest and abdomen in contact with the safety belt. Since the abdomen has no skeletal protection, the instant strong pressure will cause the organs in the abdominal cavity, especially the small intestine and colon and their mesentery, to rupture, resulting in intestinal rupture (intestinal rupture causing diffuse peritonitis) and intra-abdominal hemorrhage (hemorrhagic shock), causing irreversible damage and life-threatening. In the case of long-term wearing of safety belts, even if the pressure is relatively small, the cumulative effect of long-term wearing will also make the abdomen gradually feel uncomfortable, affecting the comfort of travel.

[0037] Safety belts play an indispensable role in ensuring travel safety, but the strong force in an emergency braking moment and the cumulative pressure from long-term wearing can cause discomfort and even harm to the abdomen. The safety belt anti-pulling abdominal protection pad can effectively disperse the pressure of the safety belt on the abdomen by setting a clamping groove to fix the safety belt, protect the body, and avoid dangerous situations such as intestinal rupture in emergency systems, and also reduce discomfort and improve travel comfort and safety in daily use. The following is a specific embodiment.
[0038] As shown in Figures 1-2 , it shows a safety belt anti-pulling abdominal protection pad in an embodiment of the present disclosure, which includes a pad body 1, the pad body 1 has a first clamping groove 100 and / or a second clamping groove 200 on one side, the first clamping groove 100 is transversely used to clamp the transverse part of the safety belt, and the second clamping groove 200 is obliquely used to clamp the oblique part of the safety belt.
[0039] The overall design of the pad body 1 is an ergonomic shape that conforms to the curvature of the human abdomen, with a long axis length of about 25-30 cm and a short axis length of about 18-22 cm, to ensure that it can cover the area where the safety belt mainly contacts the abdomen. In terms of thickness, considering the balance between comfort and protection effect, the middle part is thicker, about 3-5 cm, and the edge part gradually thins to 1-2 cm, which can effectively disperse the pressure and not make the user feel too heavy.
[0040] The pad body 1 selects soft and elastic memory foam as the main material, which can automatically adjust the shape according to the pressure applied by the human body, fit the abdominal curve, and effectively disperse the pressure. The surface of the memory foam is covered with a skin-friendly and breathable fabric such as cotton mesh, ensuring comfort when in contact with the skin, while ensuring good breathability to avoid a stuffy feeling from long-term wearing. To enhance the durability of the pad body 1, a layer of wear-resistant leather material is added at the bottom to prevent the pad body from being worn during use.
[0041] The first clamping groove 100 is transversely arranged near the upper edge of the pad body 1, with a length of about 2 / 3 of the long axis of the pad body and a width slightly larger than the width of the transverse part of the safety belt, to ensure that the safety belt can be easily clamped and not easily come out. The depth of the clamping groove is about 0.3-0.6 cm, which can effectively fix the safety belt and not affect the normal function of the safety belt due to excessive depth. To make the safety belt clamped more smoothly, the edges of the clamping groove are rounded to avoid scratching the safety belt.
[0042] As an option, the second slot 200 is obliquely arranged on the pad 1, and the oblique angle is matched with the fitting angle of the oblique part of the vehicle safety belt on the human abdomen, generally 40°-60°. The length is about 1 / 2 of the long axis of the pad, the width is the same as the first slot 100, and the depth is also kept at 0.3-0.6 cm. Similarly, the edges of the second slot 200 are rounded to facilitate the clamping and fixing of the oblique part of the safety belt.
[0043] In use, the pad 1 is placed on the abdominal position, with the center of the pad aligned with the center of the abdomen. Then, the transverse part of the safety belt is clamped into the first slot 100, and the oblique part is clamped into the second slot 200. In this way, the pressure of the safety belt is evenly distributed on the pad 1, and then distributed to a larger area of the abdomen by the pad 1, thereby reducing the pressure on the local abdomen.
[0044] The protective pad can be easily used without complex modification of the vehicle safety belt system. It can be used on private cars, buses and other vehicles as long as there is a regular three-point safety belt. Moreover, it can be easily removed when not in use, making it easy to store and carry.
[0045] When the vehicle is in emergency braking or long driving, the tension of the safety belt is transmitted to the pad 1 through the first slot 100 and the second slot 200. The memory foam material of the pad 1 automatically deforms according to the pressure, evenly distributing the pressure concentrated at the contact point of the safety belt and the abdomen to the entire contact surface of the pad and the abdomen. Due to the increase in contact area, the pressure per unit area is reduced, effectively reducing the pain felt by the abdomen and protecting the human body, and avoiding the risk of intestinal rupture in emergency braking.
[0046] The oval design that conforms to the curve of the human abdomen and the self-adaptive properties of the memory foam enable the pad 1 to closely fit the abdomen, ensuring user comfort while dispersing pressure. Even if the human posture changes during vehicle driving, the pad 1 can still better fit the abdomen and continuously play a role in dispersing pressure.
[0047] Through the clamping of the slot and the dispersion of the pad, the pain felt by the abdomen during emergency braking is significantly reduced. Through actual testing, the peak pressure on the abdomen during emergency braking is reduced after using the protective pad, effectively relieving the pain caused by the tension of the safety belt and avoiding the risk of intestinal rupture in emergency braking.
[0048] During long-term driving, the protective pad continuously and evenly disperses the pressure of the safety belt, effectively reducing the tightness and soreness of the abdomen. Users have feedback that after wearing the protective pad, they can maintain a relatively comfortable state during a long journey, improving the overall comfort of travel.
[0049] The simple design of the protective pad makes it suitable for various three-point seat belt equipped vehicles, without complex installation, convenient to carry and use. Whether it is daily commuting, long-distance travel or riding different types of vehicles, it can be used at any time, providing convenient protection against choking for the majority of travelers.
[0050] The selected memory foam, skin-friendly breathable fabric and wear-resistant leather material ensure that the protective pad has good durability and can withstand long-term use. At the same time, the relatively simple structure and material selection make the protective pad have a lower cost and a higher cost performance, easy to promote and use.
[0051] In some examples, as shown in Figure 2 The two sides of the first clamping groove 100 and the two sides of the second clamping groove 200 are provided with a stop edge 102, which makes the first clamping groove 100 and the second clamping groove 200 T-shaped clamping grooves.
[0052] The stop edge 102 is provided on both sides of the first clamping groove 100 and the second clamping groove 200 and is integrally formed with the pad body 1, and the material is also selected as memory foam to ensure the overall softness and elasticity. The appropriate size is designed to effectively prevent the seat belt from coming out of the clamping groove from the side, ensure that the seat belt is always in a stable position in the clamping groove, and also will not affect the fit of the seat belt and the pad body and the comfort of the user due to being too high and too wide.
[0053] The first clamping groove 100 and the second clamping groove 200 form T-shaped clamping grooves due to the stop edge 102, which enhances the fixing effect of the seat belt. During vehicle driving, especially when encountering bumps, sudden braking, etc., the seat belt is easily displaced laterally due to external force. The structure of the T-shaped clamping groove makes the seat belt limited by the stop edge 102 in the clamping groove, effectively reducing the possibility of lateral sliding, always maintaining in the predetermined position, ensuring that the pressure can be stably dispersed by the pad body 1 to the abdomen.
[0054] When the seat belt is clamped into the first clamping groove 100 and the second clamping groove 200, the trapezoidal structure of the stop edge 102 guides the seat belt to smoothly enter the clamping groove. When the seat belt is subjected to external force during vehicle driving, the stop edge 102 limits the seat belt from both sides, preventing it from coming out of the side of the clamping groove. Even if it encounters severe bumps or emergency braking, the seat belt can be stably fixed in the T-shaped clamping groove and maintained in the appropriate position.
[0055] Through the design of the T-shaped clamping groove, in the test of simulating various complex road conditions and emergency braking, the seat belt can be more stably fixed in the predetermined position, providing reliable protection for effectively dispersing pressure. Since the seat belt is stably positioned in the T-shaped clamping groove, the pressure is more evenly dispersed.
[0056] In some examples, as shown in Figure 2As shown, the end of the blocking edge 102 close to the first clamping groove 100 is a right-angle structure 103, and the end away from the first clamping groove 100 is a rounded structure 104.
[0057] In actual use, for example, when the safety belt is clamped into the first clamping groove 100, the right-angle structure 103 can closely fit with the safety belt, providing stable support and restriction to prevent the safety belt from moving horizontally in the first clamping groove 100. The rounded structure 104 reduces the scratching and discomfort that the end of the blocking edge 102 may cause to the human body, improving the comfort of wearing.
[0058] The advantages of this design are: first, the right-angle structure 103 enhances the fixing effect of the safety belt, ensuring the stability of the protective pad in use. Second, the rounded structure 104 improves the comfort when the human body is in contact, avoiding the harm and discomfort that sharp edges may cause.
[0059] For example, during a long car ride, the reliable fixation of the safety belt can be ensured, and the passenger can hardly feel the existence of the blocking edge 102.
[0060] In terms of technical effects, it realizes the optimization of the human body contact experience while ensuring the protection function. Overall working principle: the right-angle structure 103 closely fits with the safety belt, and the rounded structure 104 reduces friction and discomfort with the human body. Overall technical effect: through the structural design of the end of the blocking edge 102, the functionality and comfort of the protective pad are improved.
[0061] In some examples, as shown in Figure 3 The pad body 1 also has a plurality of air holes 101 to improve the air permeability of the pad body 1 and avoid discomfort caused by poor air permeability.
[0062] In some examples, as shown in Figures 4-7 The pad body 1 includes a soft pad body 105; a connecting plate 106 is arranged on one side of the soft pad body 105; a clamping plate 107 is arranged on the connecting plate 106, and the clamping plate 107 has a first clamping groove 100.
[0063] In the present safety belt anti-pinch abdominal protective pad: the pad body 1 is composed of a soft pad body 105, a connecting plate 106 and a clamping plate 107. The soft pad body 105 directly contacts the abdomen, and its soft material can provide a comfortable touch and good cushioning effect, reducing the pressure of the safety belt on the abdomen. The connecting plate 106 is arranged on one side of the soft pad body 105, serving as a connection and support. The clamping plate 107 is arranged on the connecting plate 106, and the clamping plate 107 has a first clamping groove 100 for clamping the safety belt.
[0064] In actual use, for example, when the passenger wears the protective pad, the soft pad body 105 is attached to the abdomen, the connecting plate 106 connects the soft pad body 105 and the clamping plate 107 into a whole, and the clamping plate 107 is stably clamped to the safety belt through the first clamping slot 100, thereby realizing the overall function of the protective pad.
[0065] The advantages of this design are: first, the soft pad body 105 can effectively alleviate the pressure on the abdomen and improve comfort. Second, the combined structure of each component is reasonable, making the installation and use of the protective pad more convenient and reliable.
[0066] For example, when passengers of different sizes use it, the adaptability of the soft pad body 105 and the stability of the clamping plate 107 can achieve good protection effect.
[0067] In terms of technical effects, through reasonable structure division, the comfort and functionality of the protective pad are unified. The overall working principle: the soft pad body 105 contacts the abdomen, the connecting plate 106 connects each component, and the first clamping slot 100 of the clamping plate 107 clamps the safety belt to work cooperatively. Through the division of labor of the components, the performance and effect of the protective pad are improved.
[0068] In some examples, as shown in Figures 4-7 The connecting plate 106 has a sliding slot 108, and the length direction of the sliding slot 108 is perpendicular to the length direction of the first clamping slot 100, and the clamping plate 107 is slidingly arranged in the sliding slot 108.
[0069] In actual application, for example, when passengers of different sizes use it, by sliding the clamping plate 107 in the sliding slot 108, the position of the clamping plate 107 and the first clamping slot 100 can be adjusted to adapt to safety belts of different positions and angles, ensuring that the protective pad can accurately cooperate with the safety belt.
[0070] The advantages of this design are: first, it increases the flexibility of the protective pad, which can meet the needs of different individuals and use scenarios. Second, it improves the matching degree of the protective pad and the safety belt, so that it can provide effective protection in various situations.
[0071] For example, for passengers with higher or shorter body, or in the case of different seat positions resulting in changes in the angle of the safety belt, the position of the protective pad can be adjusted by sliding the clamping plate 107 to achieve the best protection effect.
[0072] In terms of technical effects, the versatility and adaptability of the protective pad are significantly improved. The overall working principle: according to the actual use, the relative position of the protective pad and the safety belt is adjusted by sliding the clamping plate 107 in the sliding slot 108. The overall technical effect: through the sliding structure, the use experience of the protective pad is optimized, and the application range and protection effect are enhanced.
[0073] In some examples, as Figures 4-7 As shown in the figure, the groove wall of the sliding groove 108 has a plurality of limiting grooves 109, the side wall of the clamping plate 107 close to the first clamping groove 100 has a guide groove 110, the length direction of the guide groove 110 is perpendicular to the length direction of the sliding groove 108, and further includes a moving clamping piece 111, the moving clamping piece 111 is slidingly arranged in the guide groove 110, and the end portion has a clamping head 112 for clamping in one of the plurality of limiting grooves 109; the elastic piece 113 acts on one end of the moving clamping piece 111 and on the other end of the groove bottom of the guide groove 110, providing a force for the clamping head 112 to be clamped in the limiting groove 109.
[0074] In the safety belt anti-pulling abdominal protection pad, the groove wall of the sliding groove 108 is provided with a plurality of limiting grooves 109, and the side wall of the clamping plate 107 close to the first clamping groove 100 has a guide groove 110. The moving clamping piece 111 is slidingly arranged in the guide groove 110, and the clamping head 112 at the end portion is used for clamping in one of the plurality of limiting grooves 109. The elastic piece 113 acts on one end of the moving clamping piece 111 and on the other end of the groove bottom of the guide groove 110.
[0075] In actual use, for example, when it is necessary to adjust the position of the clamping plate 107 in the sliding groove 108, an external force is applied to the clamping plate 107 to overcome the elastic force of the elastic piece 113, so that the clamping head 112 of the moving clamping piece 111 is detached from the current limiting groove 109, and at this time the clamping plate 107 can be slid. When adjusted to the appropriate position, the external force is released, and the elastic force of the elastic piece 113 makes the clamping head 112 re-enter the corresponding limiting groove 109, thereby fixing the position of the clamping plate 107.
[0076] The advantages of this design are: first, the convenience and fixability of the position adjustment of the clamping plate 107 are realized, which can be flexibly adjusted and stably maintained. Second, through the cooperation of the limiting groove 109 and the clamping head 112, the position accuracy and stability after adjustment are ensured.
[0077] For example, during vehicle driving, even if affected by vibration and the like, the clamping plate 107 can be maintained at the set position to provide continuous and stable protection.
[0078] In terms of technical effects, the convenience of adjustment and the reliability of use of the protection pad are significantly improved. The overall working principle is that the position of the clamping plate 107 is adjusted by an external force, and the elastic piece 113 makes the clamping head 112 cooperate with the limiting groove 109 to fix the position. The overall technical effect is that through the ingenious structure design, the adjustment and fixing mechanism of the protection pad is optimized, and the performance and practicality of the product are improved.
[0079] In some examples, as Figures 4-7As shown, the clamping head 112 is a trapezoidal clamping head, and the limiting groove 109 is a trapezoidal limiting groove. In actual application, for example, when adjusting the position of the clamping plate 107, the trapezoidal clamping head 112 and the trapezoidal limiting groove 109 have unique advantages when cooperating with each other. The trapezoidal shape makes the clamping head 112 more smooth when entering and exiting the limiting groove 109, and can provide stable clamping force after clamping to prevent the clamping head 112 from easily coming out.
[0080] The advantages of this design are: first, it improves the smoothness of the adjustment operation and reduces the jamming and resistance. Second, it enhances the stability after clamping to ensure that the clamping plate 107 does not accidentally slide during use. For example, in the case of frequent adjustment of the position of the protective pad, the trapezoidal structure can maintain good performance and is not prone to failure.
[0081] In terms of technical effects, the performance of the clamping plate 107 adjustment and fixation is further optimized. Overall working principle: The trapezoidal clamping head 112 and the limiting groove 109 facilitate relative sliding during adjustment and provide reliable fixation during clamping. Overall technical effect: Through the trapezoidal shape, the reliability of the protective pad structure and the convenience of operation are improved.
[0082] In some examples, as shown in Figures 4-7 As shown, the soft pad body 105 has an arc surface 114 on the side that contacts the abdomen. In actual use, for example, when the passenger wears the protective pad, the arc surface 114 can better fit the curve of the abdomen, increase the contact area, and thus more evenly distribute the pressure of the seat belt, improving comfort.
[0083] The advantages of this design are: first, the arc surface 114 can adapt to the shape changes of the abdomen under different body types and sitting postures, providing more comfortable support. Second, it increases the contact area and reduces the pressure per unit area, further reducing the discomfort of the abdomen.
[0084] For example, whether the passenger is thin or obese, the arc surface 114 can provide good fitting effect and effectively avoid local pressure concentration.
[0085] In terms of technical effects, the fit and pressure dispersion effect of the protective pad and the abdomen are significantly improved. Overall working principle: The shape of the arc surface 114 naturally fits the abdomen, achieving uniform pressure dispersion. Overall technical effect: By optimizing the shape of the contact surface of the soft pad body 105, the comfort and protection performance of the protective pad are improved.
[0086] In some examples, the soft pad body 105 has a smooth transition type 115 around it. In actual use, for example, after the passenger wears the protective pad, the smooth transition type 115 around it can reduce friction with clothing or skin, avoiding discomfort or even scratches.
[0087] The advantages of this design are: first, it improves the wearing comfort, making the protective pad more smooth in contact with the body; second, it enhances the safety of the protective pad, reducing the risk of accidental injury caused by sharp or rough edges.
[0088] For example, during a long ride, the passenger's body movement will not be hindered by the soft pad body 105, and the clothes will not be caught or worn out.
[0089] In terms of technical effects, the use experience of the protective pad is significantly improved, and its safety and comfort are enhanced. Overall working principle: thanks to the smooth transition type 115 around, the friction and obstruction with the surrounding are reduced. Overall technical effect: by optimizing the edge design of the soft pad body 105, the comprehensive performance of the protective pad is improved.
[0090] In some examples, the connecting plate 106 is a rounded rectangle. In this seat belt anti-choking abdominal protective pad, the connecting plate 106 is designed as a rounded rectangle, which has multiple meanings. In terms of comfort, the rounded design can reduce the sharpness when the protective pad is in contact with the body, avoiding pressure or discomfort to the body, especially when wearing for a long time, which can improve the comfort of use. In terms of safety, it avoids the scratches or bruises that right angles may cause, reducing the risk of accidental injury. In terms of aesthetics, the rounded rectangular shape is more soft and smooth, which meets the aesthetic concept of the public, can improve the overall appearance quality of the product, and increase the attractiveness of the product.
