Description

Technical Field

[0001] This invention relates to helmets, and more specifically to helmets in which a liner integrated with the interior of the helmet can be removed in an emergency. Background Technology

[0002] For two-wheeled vehicles, the risk of the impact being directly transmitted to passengers in the event of an accident is very high. Therefore, it is required that passengers of two-wheeled vehicles wear a helmet to protect their heads.

[0003] Typically, a helmet consists of: an outer shell that initially protects the wearer's head from external impacts; and a liner that integrates with the inside of the outer shell. In this way, the liner, located inside the outer shell, fits snugly against the wearer's head to provide stability and prevent the helmet from easily slipping off when worn.

[0004] On the other hand, in the event of an accident requiring rescue of the wearer, the helmet needs to be removed from the wearer's head. However, the padding that is pressed tightly against the wearer's head makes it difficult to separate the helmet, and secondary injuries to the wearer's neck can occur during the forced separation of the helmet.

[0005] Therefore, there is a current need to develop helmets that have padding that is stably fixed inside the helmet, providing a comfortable wearing experience, and that can be easily removed in an emergency in the event of an accident, so that the helmet can be easily detached from the wearer's head.

[0006] (Existing Documents) Korean Patent No. 1995947, "Helmet with Removable Padding in Emergency", granted on July 3, 2019. Summary of the Invention

[0007] Technical issues

[0008] The present invention addresses the problems of the prior art described above. The purpose of the present invention is to provide a helmet in which the padding disposed between the outer shell and the wearer's head in conjunction with the interior can be effectively removed by means of a force with a specific direction, and which can be easily separated from the wearer's head in an emergency.

[0009] Solution to the problem

[0010] According to one embodiment of the present invention, a helmet is provided comprising: a helmet body; a liner, which is combined with the interior of the helmet body; and a fastening unit that allows the helmet body and the liner to be separably combined. The fastening unit comprises: an outer fastening member disposed in one of the interior of the helmet body and the liner; and an inner fastening member disposed in the other of the interior of the helmet body and the liner, which is inserted to fix the outer fastening member. The outer fastening member has a first inclined surface in the portion inserted to fix the inner fastening member, and the inner fastening member has a second inclined surface corresponding to the first inclined surface. When an external force is applied to the liner in a first direction while the outer fastening member and the inner fastening member are combined, causing the outer fastening member to separate from the inner fastening member, the first inclined surface moves along the second inclined surface to separate the liner from the helmet body.

[0011] At this time, the aforementioned external fastening component may include: a base portion, which is attached to the interior of the helmet body or one of the aforementioned padding; an extension portion, which extends outward from one side of the base portion and has the aforementioned first inclined surface on one side; and an expansion end portion, which is provided at the end of the extension portion in the extension direction, at least a portion of which extends outward in a direction perpendicular to the extension direction of the extension portion.

[0012] Furthermore, the portion of the extension with the first inclined surface in the middle can protrude further outward than the expansion end in a direction perpendicular to the extension direction.

[0013] Furthermore, the helmet may also include a cover plate, which is configured to cover one side of the interior of the helmet body or one of the pads, so that the base portion is attached.

[0014] Furthermore, the cover plate may have a through hole of a size that prevents the base portion from passing through. The base portion may be disposed inside the helmet body or between the pad and the cover plate, and the extension portion extends through the through hole.

[0015] Furthermore, the aforementioned extension may include: a first extension extending through the aforementioned through hole; and a second extension disposed between the aforementioned first extension and the aforementioned expansion end, having the aforementioned first inclined surface on one side.

[0016] Furthermore, the helmet may also include: a fixing part fixed to the cover plate; and a movement prevention component, including a movement prevention part connected to the fixing part, so as to fasten to the extension part to prevent the movement of the external fastening component.

[0017] Furthermore, the second extension may include a fastening part for securing the anti-slip part, and the anti-slip part may be secured to the fastening part.

[0018] Furthermore, the aforementioned internal fastening component may include: a body having a receiving space for receiving at least a portion of the aforementioned extension and the aforementioned expanded end, having the aforementioned second inclined surface on one side of the inner wall of the receiving space; and an opening formed in communication with the aforementioned receiving space in the aforementioned body.

[0019] Furthermore, the opening may include: a first portion that surrounds the extension; and a second portion that is connected to the first portion and forms a slot that exposes the second inclined surface.

[0020] Furthermore, the aforementioned second inclined surface and the aforementioned second portion may be wider than the aforementioned expanded end.

[0021] Furthermore, in the helmet described above, the padding may also include a pulling part that can be pulled by an external force in the first direction, and the first inclined surface and the second inclined surface may be oriented toward an imaginary location extending toward the pulling part or the first direction.

[0022] The effects of the invention

[0023] According to the present invention, when an external force is applied in a specific direction based on the interaction of the first inclined surface and the second inclined surface, the padding can be easily separated from the inside of the helmet body, thereby allowing the helmet to be safely separated from the wearer's head in an emergency.

[0038] Figure 1 This is a perspective view of a helmet according to an embodiment of the present invention. Furthermore, Figure 2 This is an exploded perspective view of a helmet according to an embodiment of the present invention.

[0039] Reference Figure 1 and Figure 2 A helmet according to an embodiment of the present invention includes: a helmet body 100; a pad 200, which is combined with the interior of the helmet body 100; and a fastening unit 300, which combines the helmet body 100 and the pad 200 in a separable manner.

[0040] The helmet body 100 serves to protect the wearer's head. The helmet body 100 may be formed from an impact-absorbing material. For example, the helmet body 100 may include: an outer shell 110 formed from a rigid synthetic resin or the like, possessing high strength; and an impact absorber 120 disposed inside the outer shell 110. In this case, the impact absorber 120 may be formed from expanded polystyrene (EPS) or the like.

[0041] In one embodiment of the invention, the pad 200 may be attached to the inner wall of the impact absorber 120 using the fastening unit 300. However, the helmet body 100 does not necessarily need to include the impact absorber 120, and the pad 200 does not necessarily need to be attached to the inner wall of the impact absorber 120; it may be attached to any other part of the interior of the helmet body 100.

[0042] An open opening 130 may be provided at the front of the helmet body 100 to ensure the user's field of vision. Furthermore, the opening 130 can be opened and closed by means of a shield 140 that is rotatably combined with the helmet body 100.

[0043] The pad 200 is disposed between the inside of the helmet body 100 and the wearer's head, providing a stable wearing experience. In one embodiment of the invention, the pad 200 can be attached to the interior of the helmet body 100 (e.g., the inner wall of the shock absorber 120) in a manner detachable by the fastening unit 300. The pad 200, attached to the interior of the helmet body 100, can contact the helmet wearer's chin, cheeks, ears, etc.

[0044] The padding 200 provides cushioning between the wearer's head and the helmet body 100, and is elastic to adapt to the shape of the wearer's head. Furthermore, the cover 400 can be configured to cover either the interior of the helmet body 100 or one side of the padding 200. In one embodiment of the invention, the cover 400 is disposed on one side of the padding 200 (the side in contact with the helmet body 100). That is, the cover 400 can cover one side of the padding 200 and is disposed between the interior surface of the helmet body 100 and one side of the padding 200.

[0045] The fastening unit 300 includes: an outer fastening member 310 disposed in one of the interior of the helmet body 100 and the padding 200; and an inner fastening member 320 disposed in the other of the interior of the helmet body 100 and the padding 200, which is inserted to fix the outer fastening member 310.

[0046] Figure 3 The diagram shows the fastening state between the helmet body and the liner in a helmet according to an embodiment of the present invention. Figure 4 Show Figure 3 The exploded diagram. And, Figure 5 A perspective view of the outer fastening member of a helmet fastening unit according to an embodiment of the present invention is shown. Figure 6 A diagram is shown illustrating the fastening states of the outer and inner fastening components of a helmet fastening unit according to an embodiment of the present invention. Figure 6 The diagrams of the helmet body 100, padding 200, and cover plate 400 are omitted.

[0047] Reference Figures 3 to 6 The outer fastening member 310 has a first inclined surface 311 at the portion inserted into and fixed to the inner fastening member 320, and the inner fastening member 320 has a second inclined surface 321 corresponding to the first inclined surface 311. When the outer fastening member 310 and the inner fastening member 320 are engaged, and an external force is applied to the pad 200 in a first direction to facilitate the separation of the outer fastening member 310 from the inner fastening member 320, the first inclined surface 311 moves along the second inclined surface 321, releasing the engagement of the outer fastening member 310 and the inner fastening member 320, allowing the pad 200 to be easily separated from the helmet body 100.

[0048] The external fastening member 310 may include: a base portion 312, which is attached to the interior of the helmet body 100 or the padding 200; an extension portion 313, which extends outward from one side of the base portion 312 and has a first inclined surface 311 on one side; and an expansion end portion 314, at least a portion of which is provided at the extension end portion 313 in the extension direction direction, which expands outward from the extension portion 313 in a direction perpendicular to the extension direction of the extension portion 313.

[0049] In one embodiment of the invention, the base portion 312 is attached to the side of the pad 200 by means of a cover plate 400. For example, the base portion 312 may be formed of a plate, and the cover plate 400 may have a through hole 410 of a size formed to prevent the base portion 312 from passing through, with the base portion 312 disposed between the pad 200 and the cover plate 400. On the other hand, in another embodiment where the external fastening member 310 is provided on the side of the helmet body 100, the base portion 312 may be attached to the interior of the helmet body 100.

[0050] Extension 313 can extend through through hole 410 (see reference) Figure 3 and Figure 4 More specifically, the extension 313 may include: a first extension 313a extending through the through hole 410; and a second extension 313b disposed between the first extension 313a and the expansion end 314, having a first inclined surface 311 on one side.

[0051] The first extension 313a may be shaped to correspond to the shape of the through hole 410 and extend to one side of the base portion 312. When the first extension 313a and the through hole 410 have corresponding shapes, it is beneficial for the external fastening member 310 to be stably attached to the cover plate 400.

[0052] The second extension 313b may include: a fastening portion 3131 for fastening the anti-slip member 500; and an additional extension 3132 that extends further from the fastening portion 3131 in the extension direction and has a first inclined surface 311 on one side. The first inclined surface 311 may be formed inclined from the outside to the inside in a direction perpendicular to the extension direction along the extension direction of the extension 313b. Furthermore, the fastening portion 3131 of the second extension 313b has a cross-sectional area smaller than that of the additional extension 3132 and the first extension 313a of the second extension 313b. When the anti-slip member 500 is engaged with the fastening portion 3131, movement in the extension direction can be restricted by the first extension 313a and the additional extension 3132.

[0053] In one embodiment of the invention, the outer fastening member 310 is attached to the side of the pad 200, which is elastic. Therefore, when the outer fastening member 310 is engaged with the inner fastening member 320, the outer fastening member 310 can apply pressure to the side of the pad 200 and move. This may hinder a smooth fastening between the outer fastening member 310 and the inner fastening member 320. The movement prevention member 500 is provided to prevent such movement of the outer fastening member 310.

[0054] The anti-move component 500 may include: a fixing portion 510 fixed to the cover plate 400; and an anti-move portion 520 connected to the fixing portion 510 to secure it to the extension portion 313 to prevent the outer fastening component 310 from moving. More specifically, the fixing portion 510 may be formed by a hook that is attached to a hook hole 420 formed in the cover plate 400, and the anti-move portion 520 may be formed by a C-ring that is fastened in a manner surrounding the fastening portion 3131.

[0055] Of course, the structure of the anti-slip member 500 is not limited to this. The fastening structure between the fixing part 510, the anti-slip part 520 and the fastening part 3131 fixed to the cover plate 400 can be deformed in various forms. For example, the anti-slip part 520 can be formed by an outer fastening part and the fastening part 3131 can be formed by an inner fastening part.

[0056] With the outer fastening member 310 fastened to the inner fastening member 320, the expansion end 314 is attached to the receiving space S of the inner fastening member 320. When no force is applied in the first direction, but a force is applied in another direction so that separation between the outer fastening member 310 and the inner fastening member 320 can be achieved by moving only along the path of the first inclined surface 311 of the outer fastening member 310 along the second inclined surface 321 of the inner fastening member 320, the expansion end 314 may be in a shape that interferes with the opening 323 of the inner fastening member 320.

[0057] The expansion end 314 can be shaped such that its cross-sectional area can be deformed by means of elasticity. Thus, when passing through the opening 323 of the inner fastening member 320, the expansion end 314 can deform its cross-sectional area by means of elasticity, enter the receiving space S, and restore its expanded cross-sectional area within the receiving space S.

[0058] On the other hand, in one embodiment of the invention, the portion of the extension 313 having the first inclined surface 311 in the middle can protrude further outward than the expansion end 314 in a direction perpendicular to the extension direction of the extension 313. In this way, when the first inclined surface 311 protrudes further to one side than the expansion end 314, if an external force is applied in the first direction, the first inclined surface 311 can move smoothly along the second inclined surface 321 of the inner fastening member 320 without interference from the expansion end 314.

[0059] Reference Figure 4 and Figure 6 The internal fastening component 320 may include: a body 322 having a receiving space S to receive at least a portion of the extension 313 and the expanded end 314, and having a second inclined surface 321 on one side of the inner wall of the receiving space S; and an opening 323 formed in communication with the receiving space S in the body 322. In this case, the second inclined surface 321 has a shape corresponding to the first inclined surface 311.

[0060] The opening 323 may include: a first portion 323a, which surrounds the extension 313; and a second portion 323b, which is connected to the first portion 323a and forms a slot that exposes the second inclined surface 321. More specifically, in one embodiment of the invention, the first portion 323a may be arched and the second portion 323b may be rectangular.

[0061] Figure 7 This diagram illustrates the process by which the first inclined surface of the outer fastening member of a helmet fastening unit according to an embodiment of the present invention moves along the second inclined surface of the inner fastening member, causing the outer fastening member to separate from the inner fastening member. Figure 8 This diagram illustrates the state in which the outer fastening member of the helmet's fastening unit is separated from the inner fastening member according to an embodiment of the present invention. Figure 7 and Figure 8 The helmet body 100, padding 200 and cover plate 400 are omitted from the diagram.

[0062] Reference Figure 7 and Figure 8 In the state where the outer fastening member 310 and the inner fastening member 320 of the helmet fastening unit 300 according to an embodiment of the present invention are fastened, the expansion end 314 of the outer fastening member 310 is attached to the receiving space S of the inner fastening member 320. Unless an external force is applied to the first inclined surface 311 in the direction that can move along the second inclined surface 321, i.e., the first direction, the expansion end 314 cannot pass through the opening 323 of the inner fastening member 320. Thus, the outer fastening member 310 and the inner fastening member 320 maintain the coupled state, and the pad 200 is stably fixed to the inner surface of the helmet body 100.

[0063] When the outer fastening member 310 and the inner fastening member 320 are fastened, and an external force is applied in the first direction, i.e., the direction in which the first inclined surface 311 can move along the second inclined surface 321, the first inclined surface 311 moves along the second inclined surface 321, thereby allowing the expansion end 314 to detach from the receiving space S through the second portion 323b of the opening 323 of the inner fastening member 320. As a result, the engagement of the outer fastening member 310 and the inner fastening member 320 is released, and the pad 200 separates from the helmet body 100.

[0064] Related to it, such as Figure 9 As shown, the second inclined surface 321 and the second portion 323b may be wider than the expansion end 314. Specifically, the width W2 of the second inclined surface 321 and the second portion 323b of the opening 323 is greater than the width W1 of the expansion end 314 of the outer fastening member 310. Therefore, when a force is applied in the first direction while the outer fastening member 310 and the inner fastening member 320 are fastened, the expansion end 314 attached to the receiving space S can easily detach through the second portion 323b of the opening 323 as the first inclined surface 311 moves along the second inclined surface 321.

[0065] On the other hand, when the width W2 of the second inclined surface 321 and the second part 323b of the opening 323 is greater than the width W1 of the expansion end 314 of the outer fastening member 310, the expansion end 314 of the outer fastening member 310 can be allowed to enter the receiving space S through the second part 323b of the opening 323 while the outer fastening member 310 and the inner fastening member 320 are separated, and the fastening between the outer fastening member 310 and the inner fastening member 320 can be easily achieved.

[0066] Figure 10This diagram illustrates the arrangement and orientation of the internal fastening components of a helmet fastening unit according to an embodiment of the present invention.

[0067] In one embodiment of the present invention, pads 200 are respectively disposed on the left and right sides of the interior of the helmet body 100. Furthermore, to enable the helmet body 100 to be coupled with the pads 200, multiple fastening units 300 are provided on each of the left and right sides. To remove the pads 200, it is necessary to release the coupling between the outer fastening member 310 and the inner fastening member 320 of each fastening unit 300. This means that the first inclined surface 311 of the outer fastening member 310 of each fastening unit 300 needs to move along the second inclined surface 321 of the inner fastening member 320. Therefore, preferably, the first inclined surface 311 and the second inclined surface 321 of each fastening unit 300 are oriented in such a way that the first inclined surface 311 can move along the second inclined surface 321 by means of a force in one direction.

[0068] Reference Figure 10 It can be confirmed that the second inclined surface 321 of each inner fastening member 320 is oriented toward the point of application of the force or the extension line of the direction of application of the force, so that the engagement state of multiple fastening units 300 can be simultaneously released by a force acting in the downward direction in the figure (indicated by the arrow). Of course, the first inclined surface 311 of each outer fastening member 310 is also configured to correspond to the orientation of each second inclined surface 321.

[0069] Figure 11 The figure illustrates a method for removing the emergency liner of a helmet according to an embodiment of the present invention.

[0070] Reference Figure 11 In a helmet according to an embodiment of the present invention, the pad 200 may include a pull portion 210 that can be pulled by an external force in a first direction. More specifically, the pull portion 210 is provided on the lower part of the pad 200 such that the pad 200 can be pulled from the wearer's head toward the body. The force in the first direction that moves the first inclined surface 311 of the outer fastening member 310 of each fastening unit 300 along the second inclined surface 321 of the inner fastening member 320 becomes a force acting from the wearer's head toward the body.

[0071] In one embodiment of the invention, the first inclined surface 311 of the outer fastening member 310 and the second inclined surface 321 of the inner fastening member 320 are oriented toward an imaginary location extending toward the pulling portion 210 or a first direction. This allows the fastening of the outer fastening members 310 and the inner fastening members 320 of multiple fastening units 300 to be released simultaneously with a single external force. As a result, the helmet can be easily separated from the wearer's head in an emergency, preventing secondary injuries that may occur during forced helmet removal.

[0072] The helmets according to embodiments of the present invention are generally applicable to helmets used for passenger vehicles such as two-wheeled vehicles and racing cars. However, they are not limited to this; embodiments of the present invention are applicable to all types of helmets worn during sports competitions, including skiing, sledding, and skeleton.

[0073] This invention describes one embodiment, but the concept of the invention is not limited to the embodiment presented in this specification. Those skilled in the art to which this invention pertains can easily propose another embodiment by adding, modifying, deleting, or supplementing structural elements within the same scope of the concept, which also falls within the scope of the invention.
