Description
Technical Field
[0001] This utility model relates to the field of helmet technology, specifically to a helmet liner with quick-release straps. Background Technology
[0002] Helmets are essential personal protective equipment for activities such as cycling, skiing, and construction work. Traditional helmets primarily provide protection through a tight fit between the internal cushioning liner and the head. However, in the event of an accident, especially in emergencies that may involve cervical spine injuries, safely and quickly removing the helmet becomes a critical challenge. The conventional method of removing a helmet requires prying open the sides and lifting it forcefully forward and upward or backward and upward. This process inevitably exerts significant torsional and bending stress on the user's head and neck. If the injured person already has a cervical spine injury, this method can easily cause serious secondary injuries, or even lead to permanent functional impairments such as paralysis. A typical helmet quick-release strap consists of a double-layered cord. One end of the cord is attached to the liner. After the liner is installed in the helmet, the other end of the cord extends beyond the gap between the liner and the helmet. To use it, pinch one end of the cord and pull it downwards to remove the liner.
[0003] However, the tight connection between the liner and the helmet, and the unclear quick-release path of the rope, result in excessive friction when pulling, which can easily cause operational jamming and may cause secondary injury to the neck of the injured person at critical moments.
[0004] Based on this, the present invention designs a helmet liner with quick-release straps to solve the above problems. Utility Model Content
[0005] To achieve the above objectives, this utility model provides the following technical solution: a limiting component is provided on the inner lining body, the limiting component includes a positioning post and a limiting plate, the positioning post is vertically arranged on the inner lining body, the positioning post is provided with a positioning groove around its circumference, one end of the limiting plate is fixedly connected to the positioning post, and the other end extends toward the inner lining body and is fixed, the inner lining body is provided with a disassembly part, and two quick-release straps are fixedly arranged on the disassembly part, the starting ends of the two quick-release straps are respectively located on both sides of the disassembly part, after the straps of the two quick-release straps cross, their crossing parts are respectively embedded into the positioning grooves of the positioning post from both sides, and finally extend away from the disassembly part and converge at an operating end.
[0006] By adopting the above technical solution, the structure is simple and reliable. The inner liner can be loosened by simply pulling the operating end through the linkage mechanism, which greatly facilitates the safe and quick removal of the helmet in emergency situations. The cross-set quick-release straps can pull out the inner liner more smoothly, so that the inner liner is evenly stressed. The positioning groove further limits the sliding path of the limiting strap, effectively reducing secondary injuries caused by improper helmet removal.
[0007] Preferably, the operating end is a pull ring.
[0008] By adopting the above technical solution, the pull ring provides a conspicuous and easy-to-grip operating point. In emergency situations, rescuers can quickly identify and pull the ring with one hand, significantly improving the speed and reliability of the operation and avoiding delays caused by searching for or grabbing scattered straps.
[0009] Preferably, a support block is provided at the top of the positioning column.
[0010] By adopting the above technical solution, the support block can create a space between the helmet and the inner liner body for the quick-release strap to slide. This effectively reduces the friction between the quick-release strap and the inner liner surface during the sliding process, ensuring a smooth and fluid pulling process without jamming, and guaranteeing the reliability of the quick-release function.
[0011] Preferably, the limiting plate is an arc-shaped plate that arches away from the inner lining body.
[0012] By adopting the above technical solution, the limiting plate can limit the sliding trajectory of the quick-release belt, while providing space for the limiting belt to slide.
[0013] Preferably, the disassembly part includes a base layer fixed to the inner lining body, a foldable folding layer, and a storage compartment for accommodating the folding layer, wherein the folding layer is connected to the base layer through multiple fixed connection points.
[0014] By adopting the above technical solution, the folding layer is folded in the storage compartment. When the quick-release strap is pulled in an emergency, the folding layer needs to move accordingly to release the fixation on the inner lining, reducing the internal entanglement problem that may occur after multiple uses or long-term storage.
[0015] Preferably, the edge of the folded layer is provided with an inclined bevel that converges towards the inside of the storage compartment.
[0016] By adopting the above technical solution, the beveled edges of the folded layer serve a guiding function. When the folded layer is folded and inserted into the storage compartment, the beveled edges effectively prevent the edges from curling up or getting stuck at the opening of the storage compartment, making the folding and storage actions smoother.
[0017] Preferably, the surface of the folded layer is coated with a smooth coating that reduces the coefficient of friction.
[0018] By adopting the above technical solution, the smooth coating significantly reduces the friction between the surface of the folded layer and the inner wall of the storage compartment. This makes it easier to insert and remove the folded layer from the storage compartment, further improving the convenience of disassembly and maintenance, while reducing wear and tear on the material caused by repeated folding and extending its service life.
[0019] In summary, this application has the following beneficial technical effects: the structure is simple and reliable, and the inner liner can be loosened by pulling the operating end through the linkage mechanism, which greatly facilitates the safe and quick removal of the helmet in emergency situations. The cross-set quick-release straps can pull out the inner liner more smoothly, so that the inner liner is evenly stressed. The positioning groove further limits the sliding path of the limiting strap, effectively reducing secondary injuries caused by improper helmet removal. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0025] A helmet liner with quick-release straps includes a liner body 1. A limiting component is provided on the liner body 1. The limiting component includes a positioning post 8 and a limiting plate 6. The positioning post 8 is vertically arranged on the liner body 1 and has a positioning groove 9 around it. One end of the limiting plate 6 is fixedly connected to the positioning post 8, and the other end extends toward the liner body 1 and is fixed. The liner body 1 is provided with a disassembly part. Two quick-release straps 4 are fixedly arranged on the disassembly part. The starting ends of the two quick-release straps 4 are located on both sides of the disassembly part. After the straps of the two quick-release straps 4 cross, their crossing parts are respectively embedded into the positioning grooves 9 of the positioning post 8 from both sides, and finally extend away from the disassembly part and converge at an operating end.
[0026] When in use, the helmet is worn normally. The limiting component and positioning groove 9 reliably restrain the quick-release strap 4 system to the inner liner. In case of an emergency requiring the helmet to be removed, the rescuer only needs to pull the operating part backward and downward with one hand. The pulling force is transmitted through the quick-release strap 4. Because the strap body is crossed and restrained by the positioning groove 9, the quick-release strap 4 moves downward along the restraint trajectory. This pulling force is converted into a force that expands to both sides, quickly loosening the rear structure of the inner liner, including the disassembly part, expanding the space between the inner liner and the head. This allows the helmet to be removed more smoothly and quickly, effectively avoiding secondary injury to the neck of the injured person.
[0027] The operating end is set as a pull ring 7, which is a semi-circular structure formed by folding and weaving a high-strength braided rope. The ends of the two quick-release straps 4 are firmly fixed to the inside of the pull ring 7 by folding and sewing or riveting. When an emergency occurs and the helmet needs to be removed, the rescuer can quickly identify and grab the pull ring 7 with one hand and pull it backward and downward to quickly remove the inner liner body 1.
[0028] A support block 5 is provided on the top of the positioning post 8. The support block 5 effectively avoids large-area friction of the strap inside the helmet by physically raising the sliding space of the quick-release strap 4, making the pulling operation smoother and reducing the risk of jamming due to excessive friction. The limiting plate 6 is an arc-shaped plate that is recessed towards the inner liner body 1, so that the limiting plate 6 can press against the upper surface of the quick-release strap 4, further limiting the quick-release strap 4 and reducing the possibility of the quick-release strap 4 folding.
[0029] The disassembly part includes a base layer 3 fixed to the inner liner body 1, a foldable folding layer 10, and a storage compartment 2 for accommodating the folding layer 10. The folding layer 10 is connected to the base layer 3 through multiple fixed connection points 11. The edge of the folding layer 10 is provided with an inclined bevel angle that converges towards the inside of the storage compartment 2. The surface of the folding layer 10 is coated with a smooth coating that reduces the coefficient of friction.
[0030] When the folded layer 10 is inserted into the storage compartment 2, the inclined bevel can act like a wedge to guide the edge to slide smoothly into the compartment, effectively preventing the edge from getting stuck at the compartment opening due to curling or flipping. The smooth coating provides a lubricating function, which greatly reduces the friction between the surface of the folded layer 10 and the inner wall of the storage compartment 2 as well as between its own stacked layers. This makes the folding and insertion operation extremely effortless. When under force, multiple connection points 11 enhance the connection between the liner and the folded layer 10, ensuring the stability of the connection between the folded layer 10 and the liner.
[0031] The implementation principle of this embodiment is as follows: When the rescuer pulls the pull ring 7 backward and downward, the pulling force is transmitted to the intersection of the two quick-release straps 4. The intersection is constrained in the positioning groove 9 of the positioning post 8, which acts like a fixed pulley, efficiently converting the applied longitudinal pulling force into a lateral component force that is perpendicular to the direction of the pulling force and expands to both sides. This lateral component force acts directly on the disassembly part connected to the inner liner body 1, thereby quickly pulling the inner liner downward, so that the inner liner is detached from the helmet. Finally, the entire helmet can be safely axially removed without bending the injured person's neck, effectively avoiding secondary injury.
