[0002] In many situations, the high risk necessitates the use of a hard hat. Hard hats are specifically designed to protect the human head, providing maximum protection from head impact. Made from a variety of materials, hard helmets not only withstand sudden blows, but also flying debris, particles, low-voltage electric shocks, or any combination of these three hazards. They also protect the head, face, and neck from acids, other chemicals, or high-temperature liquids pouring down from overhead. While the structural requirements for hard hats used in different hazardous locations vary, they all consist of a shell, a cushioning layer, and an inner lining.

[0003] In the prior art, the primary function of hard hats is to protect the head from impact. Consequently, the industry's design priorities are focused on high strength and impact resistance. Hard materials are typically used for the helmet shell, making it bulky and inconvenient to carry. Other manufacturers have developed integrated hats, but these typically serve only as pillows and lack any protective function, failing to effectively protect the wearer from a sudden fall. Furthermore, these hats do not block vision, covering only the top, sides, and back of the head, providing insufficient protection for the face and forehead. Summary of the Invention

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0021] Reference Figure 1 and Figure 2 Figure 1 is a schematic diagram of an embodiment of a double-opening head protection device according to the present invention. The protection device 100 comprises an airbag 10, a cap 20, and a securing portion 30. The cap 20 constrains the airbag 10 into a hat-like shape for shoulder wear. As the airbag 10 inflates, the protection device gradually expands and rises, covering the head from behind. As the airbag 10 continues to inflate, the protection device completely covers the head, providing protection. In order to prevent the brim 22 of the protective device from protruding too much, so that the brim 22 is blocked by the back of the head when the protective device is erected and cannot be erected to wrap the head, the present invention flips the brim 22 upward and uses the fixing part 30 to fix the brim 22 to the top of the protective device, so that the brim 22 will not expand immediately when inflation is first started. As the protective device covers the head, gas enters the airbag 10 in the brim 22, and the brim 22 expands in the direction away from the top of the protective device. As inflation continues, the brim 22 breaks free from the fixing part 30 and opens outward, covering the forehead and face, forming complete protection for the entire head.

[0022] Specifically, the hat skin 20 wraps the airbag 10 and restricts it to the shape of a hood 21, and the edge of the airbag 10 is fixedly connected to the hat skin 20. The provision of the hat skin 20, on the one hand, restricts the shape of the airbag 10 after inflation, reducing the processing technology of the airbag 10; on the other hand, it can protect the airbag 10. When a person falls, the hat skin 20 is the first to come into contact with the ground. Since there is friction at this time, the hat skin 20 is also damaged, thereby protecting the airbag 10 inside; at the same time, it is convenient to design the hat skin 20 to match the color of the top, etc., thereby increasing the aesthetics of the protective device of the present invention, making it suitable for daily wear, and not as abrupt as the protective gear in the prior art. In order to form complete protection for the face, the edges of the airbag 10 and the hat skin 20 extend outward to form a brim 22. Reference Figure 3As shown, the brim 22 can shield a person's forehead and face. The airbag 10 within the brim 22 is integrally connected to the airbag 10 within the protective device. As the airbag 10 is inflated, the brim 22 expands accordingly. Because the brim 22 extends outward, it can easily be blocked by the back of the head, preventing it from opening quickly. Therefore, the present invention provides a fixing portion 30. The fixing portion 30 includes a mother portion 31 and a child portion 32. The mother portion 31 is connected to the cap cover 20 at the top of the hood 21, and the child portion 32 is connected to the cap cover 20 at the top of the brim 22. The brim 22 is folded upward so that the child portion 32 and the mother portion 31 are fixed together. Because the brim 22 is folded, gas entering the protective device will not immediately enter the brim 22. Even if a small amount of gas does enter the brim 22, the brim 22 cannot be separated from the top of the hood 21 due to the fixation of the fixing portion 30, and remains folded. At this time, gas can smoothly enter the hood 21, propping it up and covering the head. As the amount of air entering increases, more gas enters the brim 22, causing the brim 22 to expand outward. The force generated by the expansion overcomes the clamping force of the mother portion 31 and the child portion 32, causing the fixing portion 30 to open. The brim 22 extends toward the forehead and face along the natural expansion direction of the airbag 10, providing protection for the entire head. To ensure that the protective device can be deployed in time when a person is about to fall and provide protection for the head, the airbag 10 is connected to an air inlet 11, which is connected to a gas generator, which is connected to a sensor chip. When the sensor chip detects that a person is about to fall, it activates the gas generator, which rapidly fills the airbag 10 with gas, thereby protecting the person before they fall and preventing injuries. In this embodiment, the air inlet 11 is located on one side of the lower portion of the airbag 20. In other embodiments of the present invention, the air inlet 11 can be located at a different location based on actual needs.

[0023] In the first embodiment of the present invention, the fixing portion 30 is a snap button. The female portion 31 of the snap button includes a panel and a female buckle, which clamp the cap 20 at the top of the hood 21. The sub-portion 32 of the snap button includes a sub-button and a foot, which clamp the cap 20 at the top of the brim 22. The female portion 31 and sub-portion 32 of the snap button are each connected only to the cap 20, without affecting the inflation of the airbag 10. This ensures that the airbag 10 can expand and break free from the snap button, thereby opening the brim 22. In other embodiments of the invention, the fixing portion 30 can also be a suture button, with the female portion 31 of the suture button sewn to the cap 20 at the top of the hood 21, and the sub-portion 32 of the suture button sewn to the cap 20 at the top of the brim 22. This facilitates the fastening of the female portion 31 and sub-portion 32, and after the airbag 10 inflates, the female portion 31 and sub-portion 32 can be stretched apart to ensure partial opening of the brim 22. In other embodiments of the present invention, the fixing portion 30 may also be a snap fastener with other similar fastening and opening methods.

[0024] In order to facilitate the connection of the protective device of the present invention with the coat, a connector 23 connected to the coat is provided at the lower portion of the cap 20. Specifically, the connector 23 is a zipper, Velcro, button or snap fastener.

[0025] To further enhance the airbag 10's resistance to external friction and collision, in this embodiment, the airbag 10 comprises an inner liner 12 and an outer layer 13. The inner liner 12 is disposed within the outer layer 13. The inner liner 12 is made of an elastomeric film material, while the outer layer 13 is made of a fabric material. The expanded size of the outer layer 13 is smaller than that of the inner liner 12. The inner liner 12 is well sealed for inflation and can withstand a certain air pressure. The outer layer 13 has a strong structural strength, capable of withstanding external friction and strong internal pressure, protecting the inner liner 12 and effectively enhancing its resistance to external friction and collision. The inner liner 12 expands after inflation due to its own elasticity, and the expanded size of the outer layer 13 is smaller than the expanded size of the inner liner 12. Therefore, the inner liner 12 can support the outer layer 13. When the inner liner 12 inflates to the limit of the outer layer 13, the inner liner 12 cannot expand further due to the restriction of the outer layer 13, so that the inner liner 12 will not over-expand. Moreover, the wrapping of the outer layer 13 ensures that the expansion degree of each part of the inner liner 12 is uniform, and there will be no bulging. At this time, the outer layer 13 and the inner liner 12 are in close contact, and the outer layer 13 becomes hard due to the uniform pressure, providing support for the inner liner 12. When the protective airbag 10 is squeezed, the inner liner 12 and the outer layer 13 jointly bear the pressure, thereby ensuring sufficient cushioning and ensuring protection for the head.

[0026] Reference Figure 3 As shown, the airbag 10 of the present invention is an enveloping airbag, capable of wrapping the head from the back of the head forward. The enveloping airbag includes a main airway 14 and claw-shaped airbag columns 15 extending to either side of the main airway 14. The claw-shaped airbag columns 15 are symmetrically arranged along the central axis of the main airway 14. Furthermore, each of the claw-shaped airbag columns 15 has a different diameter, ensuring that each column bends at a different position and angle when wrapping the head, thereby better achieving the purpose of enveloping the head after inflation. When the inflator generates gas, it enters the airbag 10 from the main airway 14 and rapidly flows into the claw-shaped airbag columns 15 on both sides. The claw-shaped airbag columns 15 inflate, enveloping the head within the constraints of the hat cover 20. Simultaneously, the brim 22 opens, protecting the head from all directions: from behind, above, front, and sides. The claw-shaped airbag columns 15 wrap around the head like claws, providing a wide and comprehensive protection area. Since the airbag 10 columns are straight columns when inflated, in this embodiment, to enable the airbag 10 columns to form an arc structure to wrap around the head, the first and second airbag columns 151, 152 are provided with several convergence angles on their sides to ensure that the airbag 10 columns form a shape that fits the head.

[0027] Furthermore, two guide lines 16 are provided within the wraparound airbag, dividing the main airway 14 into three air inlet channels 17. These guide lines 16 divide the main airway 14 into multiple sections, preventing it from excessively expanding and potentially preventing the airbag 10 from wrapping around the head. Furthermore, these guide lines 16 reduce the amount of air entering the airbag 10, accelerating its inflation. The guide lines 16 also provide a connection point between the airbag 10 and the cap 20, further stabilizing the connection and maintaining the shape of the hood 21. In this embodiment, the two guide lines 16 are arranged in a figure-eight pattern, gradually narrowing the central air inlet channel 17. Thus, the gas flows in from the main airway 14 and passes through the "figure eight" shaped guide line 16. Under the condition that the gas pressure remains unchanged, the gas channel gradually narrows, the pressure increases, and the speed increases. Therefore, after being pressurized and accelerated by the "figure eight" shaped guide line 16, it continues to flow forward, which is conducive to the rapid expansion of the terminal airway.

[0028] To provide complete head protection while preventing head compression, in this embodiment, the claw-shaped airbag columns 15 on each side of the main airway 14 include a first airbag column 151 and a second airbag column 152 corresponding to the skull and frontal bone, a third airbag column 153 corresponding to the sphenoid bone, and a fourth airbag column 154 corresponding to the mandible. The first, second, and third airbag columns 153 provide all-round protection for the upper skull, while the fourth airbag column 154 protects the mandible. As the third and fourth airbag columns 153 and 154 expand and protrude outward, space is left between them for the ears, protecting them from compression. Furthermore, the expanded third and fourth airbag columns 153 and 154 ensure that the ears do not touch the ground, thus also protecting the ears.

[0029] The above embodiments are merely preferred embodiments for the purpose of fully illustrating the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are within the scope of protection of the present invention. The scope of protection of the present invention shall be subject to the claims.
