The purpose is to provide a composite cushion and a protector that helps stress to quickly spread to the periphery from the stress concentrated part, increases the buffering area, enhances the buffering effect, maintains the shape without collapse, avoids direct contact of the user with the hard impact object, and better reduces the risk of injury.

[0007] According to one aspect of the present application, the protector includes a composite cushion, which includes: a first cushion; and a second cushion connected to one side of the first cushion, so that the first cushion and the second cushion are detachably connected or integrally formed, the first cushion is closer to the user relative to the second cushion, and the impact absorption capacity of the first cushion is smaller than that of the second cushion.

[0008] The present application is based on the above problems. According to one aspect of the present application, it can help stress to quickly spread to the periphery from the stress concentrated part, increase the buffering area, enhance the buffering effect, maintain the shape without collapse, avoid direct contact of the user with the hard impact object, and better reduce the risk of injury.

[0022] The technical solutions in the embodiments of the present application will be described in detail below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0023] The specific embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

[0024] FIRST EMBODIMENT

[0025] As shown below, in conjunction with Figs. 1 to 7, the protector 100 according to the first embodiment of the present application will be described. The protector 100 is used to protect a user from direct contact with a contact object (e.g., the ground, an obstacle, etc.), absorb impact energy between the user and the contact object, and reduce the risk of injury.

[0026] The protector 100 is formed in a planar shape and can be formed to conform to a portion of the user to which the protector 100 is fixed. For example, when the protector 100 is fixed to a joint, the protector 100 can follow the curvature of the joint, and the protector 100 can be curved away from the joint to form a curved surface. When the protector 100 is fixed to the chest or back, the protector 100 can follow the flatness of the back, and the protector 100 can be formed in a planar shape.

[0027] The protector 100 includes a composite cushion 30 and a fixing member 40.

[0028] The composite cushion 30 is used to absorb impact energy and includes a first cushion 10 and a second cushion 20 that are stacked. In the present embodiment, the first cushion 10 and the second cushion 20 are curved toward the same side and have a curved inner concave surface facing the user and a curved outer convex surface facing the outside. The first cushion 10 is disposed inward of the second cushion 20. In addition, the impact absorption capacity of the first cushion 10 is less than that of the second cushion 20, and the support stress of the second cushion 20 is greater than that of the first cushion 10.

[0029] The first cushion 10 has a first surface 10a and a second surface 10b that face each other, and in the present embodiment, the first cushion 10 is convex with the first surface 10a facing the user. The first cushion 10 is, for example, an airbag cushion, and a gas such as air is enclosed between the first surface 10a and the second surface 10b. More specifically, the first cushion 10 includes an airbag portion 1 in which the gas is enclosed.

[0030] The airbag portion 1 is formed by overlapping and joining a first pad body 110 (e.g., a combination of TPU and a Lycra portion, TPU, PVC, EVA, silicone, rubber, etc.) that constitutes the first surface 10a and a second pad body 120 (e.g., a combination of TPU and a Lycra portion, TPU, PVC, EVA, silicone, rubber, etc.) that constitutes the second surface 10b, and a plurality of airbags 101 are formed by protruding at positions where the first pad body 110 and the second pad body 120 are separated. As shown in Fig. 4, the airbags 101 are formed to protrude and stand only on the first surface 10a, and the second surface 10b is not formed with airbags 101 that protrude and stand. However, the airbags 101 can protrude toward at least one of the first surface 10a and the second surface 10b from the interface where the first pad body 110 and the second pad body 120 are joined.

[0031] Further, the plurality of air bags 101 can be in a sealed air bag form. That is, the air bags 101 do not exchange gas with the outside. Moreover, adjacent air bags 101 can be independent of each other or can be connected via the air passage 105.

[0032] In addition, the plurality of air bags 101 can be in an adjustable air bag form. That is, the air bags 101 exchange gas with the outside, thereby adjusting the degree of fullness of the gas in each air bag 101, adapting to the physical condition of different users, and providing a better use experience. For example, in the air bag portion 1 of the present embodiment, the air bag portion 1 can include a vent (not shown) and a venting member 90 provided at the vent.

[0033] One end of the vent communicates with one air bag 101 of the air bag portion 1, and the other end communicates with the outside of the air bag portion 1, so that the gas in the inside and outside of the air bag portion 1 can exchange via the vent.

[0034] As follows, referring to FIGS. 5 to 7, the venting member 90 used by the first cushion 10 of the protector 100 is described. The venting member 90 is provided at the vent, the venting member 90 prevents the exchange of gas between the inside and outside of the air bag portion 1, and can allow external devices to communicate with the inside of the air bag portion 1, and according to the function of the external devices, the gas in the inside of the air bag portion 1 can be inflated or deflated from the outside.

[0035] The venting member 90 is, for example, sandwiched between the first pad body 110 and the second pad body 120, and is installed by means of an adhesive, high-frequency voltage, laser, or the like.

[0036] Specifically, the venting member 90 has a gas nozzle 91 and a sleeve portion 92.

[0037] The air nozzle 91 is flexible, for example, made of TPU, PVC, rubber, silicone, EVA plastic, etc., and can be deformed when the air nozzle 91 is pressed. The air nozzle 91 extends in a long strip shape, and is provided with a closing part 915 at one end, which is arranged inside the air bag part 1. In addition, the air nozzle 91 can be provided with a flange part 916 on the outer peripheral surface away from the closing part 915. The flange part 916 is closer to the outside of the air bag part 1 than the closing part 915. When the sleeve part 92 is sleeved on the air nozzle 91, if the sleeve part 92 is properly fitted, the end surface of the sleeve part 92 is in contact with the flange part 916 of the air nozzle 91. Thus, the air leakage caused by improper fitting can be inhibited. The air nozzle 91 is provided with a closable channel 910 inside along the length direction, which can communicate and close the inside and outside of the air bag part 1. Along the direction from the outside to the inside of the air bag part 1, the closable channel 910 includes an insertion hole part 911, a contraction hole part 912 and a closing hole part 913 in sequence. The diameter of the insertion hole part 911 is the largest, and the diameter of the contraction hole part 912 is smaller than that of the insertion hole part 911. The diameter can be gradually narrowed from the insertion hole part 911 to the contraction hole part 912. The closing hole part 913 can be a slit cut. The closing hole part 913 can be arranged on the closing part 915 or next to the closing part 915. The closing hole part 913 is closed in the natural state, preventing gas from passing through; when the wall of the slit is pressed towards the outside, the closing hole part 913 can be opened.

[0038] The sleeve part 92 has a U-shaped structure in cross section, which is sleeved on the outer peripheral surface of the air nozzle 91 and is used to maintain the shape of the air nozzle 91. The bottom surface of the sleeve part 92 is provided with a vent hole 921. The vent hole 921 on the bottom surface of the vent hole 921 and the U-shaped opening of the sleeve part 92 expose both ends of the closable channel 910. By installing the sleeve part 92 between the first pad 110 and the second pad 120, the venting member 90 is installed in the vent hole of the air bag part 1 of the first cushion pad 10. The sleeve part 92 has supporting property and can have a certain flexibility, so the sleeve part 92 is less likely to be deformed than the air nozzle 91. The sleeve part 92 is made of TPU, PVC plastic, etc. The vent hole 921 of the sleeve part 92 is arranged opposite to the closing part 915.

[0039] In addition, the above-mentioned closing part 915 can be provided as a protrusion, which can remind personnel to fit in place on the one hand, and on the other hand, avoid the closing part 915 from being pressed and displaced when opened, so that the air leakage caused by improper recovery cannot be avoided.

[0040] When inflating, the external device such as the inflator pump with the needle 94 can be used to inflate the airbag 1 by inserting the needle 94 into the closable passage 910, and then the needle 94 is inserted into the insertion hole 911, and then squeezed through the contraction hole 912 and the closing hole 913, and then enters the inside of the airbag 1. The external gas is pumped into the inside of the airbag 1 by the inflator pump through the needle 94.

[0041] When deflating, the external device such as the needle 94 can be used to deflate the airbag 1 by inserting the needle 94 into the closable passage 910, and then the needle 94 is inserted into the insertion hole 911, and then squeezed through the contraction hole 912 and the closing hole 913, and then enters the inside of the airbag 1. The gas stored in the inside of the airbag 1 can be discharged to the outside through the closable passage 910 by squeezing the airbag 1 or using the external device such as the deflator pump connected to the needle 94.

[0042] According to the present embodiment, the airbag 1 can be inflated and deflated simultaneously by the venting member 90. In addition, the venting member 90 is flexible as a whole, which can avoid causing damage to the user when the user contacts the first cushion 10 of the protector 100.

[0043] In addition, the first cushion 10 can also be foamed by foaming material, or can also be pressed and shaped (shaped) by sponge, so that the airbag part protruding and standing on the first surface 10a can also be formed.

[0044] The second cushion 20 has a third surface 20a and a fourth surface 20b opposite to each other, and the second cushion 20 is stacked with the first cushion 10, and the second cushion 20 is recessed with the fourth surface 20b facing the second surface 10b of the first cushion 10, and the third surface 20a is the side surface of the second cushion 20 away from the first cushion 10. The second cushion 20 can include a protective member formed along the thickness direction of the third surface 20a to the fourth surface 20b. The second cushion 20 can be a resilient protective member (also referred to as a resilient protective member) made of foaming material, and the foaming material can be polyurethane (PU), and the foaming density and thickness distribution can be appropriately set as needed, and different kinds of foaming materials can be combined to form. But not limited to this, the second cushion 20 can also be a non-deformable hard protective member such as a plastic member, a metal-containing composite material, a carbon fiber composite material, etc.

[0045] In addition, the second cushion 20 can also cover a protective layer (not shown) on the third surface 20a away from the first cushion 10 by coating or bonding, which can increase the service life of the protector 100. The protective layer can be a high-performance elastomer TPU film, which can prevent the second cushion 20 from cracking. In addition, the protective layer can be a super wear-resistant polymer nano coating, which can inhibit the wear of the second cushion 20.

[0046] In addition, in order to avoid the first cushion 10 and the second cushion 20 from being displaced to affect the cushioning effect during use, the first cushion 10 and the second cushion 20 can be detachably connected via a connection mode such as magic tape, buckle fastening or magnetic attraction. The first cushion 10 which is often in contact with the user can be conveniently cleaned. It can be understood that the first cushion 10 and the second cushion 20 can also be integrally formed. For example, they can be respectively independently arranged elements, fixedly connected to each other to be integrally connected, and the connection mode can be listed as glue bonding, sewing thread sewing, high temperature or ultrasonic based welding and the like. Or by foaming the raw material of the foaming material directly on the second surface 10b of the first cushion 10 when forming the second cushion 20, the raw material of the foaming material can be foamed and formed to be connected with the first cushion 10, so that the first cushion 10 and the second cushion 20 are integrally connected by directly forming the second cushion 20 on the first cushion 10. In addition, the first cushion 10 and the second cushion 20 can also be connected via the fixing member 40.

[0047] The fixing member 40 is fixedly connected with one or both of the first cushion 10 and the second cushion 20, which can be a belt buckle, a strap and the like, but can also be, for example, a sleeve, a knee sleeve, a garment, an elastic band and the like. In addition, the present embodiment is not limited thereto, and as shown in FIG. 12, the fixing member 40 provided on the protector 100a is a sleeve, a knee sleeve, a garment and the like, which is a textile containing a pocket 410, the pocket 410 can be sewn by two separate pieces of cloth along the sewing line 41, and the unsewn part becomes the opening 411. In order to facilitate the opening and closing of the opening 411, an opening and closing structure (not shown) is provided at the opening 411, which is, for example, a buckle, a strap, a magic tape, a magnetic attraction member or a zipper. The installation, removal and the like of the composite cushion 30 relative to the fixing member 40 are more convenient and easy to operate. Therefore, the composite cushion 30 can be placed into the specified position 50 in the pocket 410 through the opening 411, so that it is convenient for the user to fix it on the body. In addition, it can be understood that the sewing line 41 can be appropriately changed, by arranging the sewing line 41 to be substantially consistent with the shape of the composite cushion 30, in other words, the sewing line 41 is sewn along the edge of the specified position 50, which can well position the composite cushion 30 and effectively inhibit the displacement of the composite cushion 30. Therefore, by embedding the composite cushion 30 in the pocket, the function of fixing the composite cushion 30 can also be achieved. It can be understood that the form of the fixing member 40 can be arbitrarily set, as long as it can fix the composite cushion to the specified position of the user and inhibit displacement.

[0048] In the case of comparing the performance of the first cushion 10 and the second cushion 20 in dynamic compression alone, the first cushion 10 absorbs less energy during impact than the second cushion 20. That is, the impact absorption capacity of the first cushion 10 is less than that of the second cushion 20. Therefore, the use of the protector 100 having the first cushion 10 and the second cushion 20 can achieve good impact absorption performance.

[0049] In addition, in the case of comparing the performance of the first cushion 10 and the second cushion 20 in static compression alone, the first cushion 10 generates less compression stress than the second cushion 20 generates when subjected to the same deformation amount (i.e., a certain strain, such as 10%, 25%, etc.). That is, the support stress of the second cushion 20 is greater than that of the first cushion 10.

[0050] Therefore, in the case of impact with a hard object, the first cushion 10 having a small support stress is more likely to deform under a small stress. Thus, when the protector 100 of the present embodiment is fixed to a prescribed part of a user, in the case of impact with a hard object, the first cushion 10 is more likely to deform quickly under stress first, and quickly spread from the stress concentrated part of the air bag part 1 to the outer periphery, and more air bags 101 are compressed and deformed, while the second cushion 20 on the back of the air bag part 1 receives the stress transmitted from the first cushion 10, and since the stress quickly spreads from the stress concentrated part to the outer periphery, the second cushion 20 is compressed over a large area, which can increase the cushioning effect, and can provide further cushioning while supporting the first cushion 10 from collapsing and deforming when the deformation amount of the first cushion 10 is large enough to bring the first surface 10a and the second surface 10b close to each other, and can avoid direct contact of the user with the impacting hard object, and better reduce the risk of injury.

[0051] Therefore, the protector 100 having the composite cushion 30 of the first cushion 10 and the second cushion 20 stacked together can achieve good cushioning and protection effects.

[0052] This result was verified by the applicant by comparing the cushioning performance of the protector 100 having the composite cushion 30 of the first cushion 10 and the second cushion 20 stacked together, and the second cushion 20, and it was found that, under the same impact energy, the protector using the composite cushion 30 received less impact force everywhere, and had better cushioning performance.

[0053]

Second Embodiment

[0054] As follows, referring to FIG. 8, the protector 100 related to the second embodiment of the present application is described. FIG. 8 is a cross-sectional schematic view showing the composite cushion 30. In the present embodiment, the first cushion 10 is formed with the first surface 10a of the air bag portion 1 facing the second cushion 20, and the first cushion 10 and the second cushion 20 are connected to each other by forming the second cushion 20 directly on the first surface 10a of the first cushion 10 when the second cushion 20 is formed, that is, the air bag portion 1 is directly fixedly connected to the second cushion 20, and other configurations are the same as those of the first embodiment.

[0055] Specifically, in the present embodiment, when the second cushion 20 is formed, the raw material of the foaming material is directly foamed on the first surface 10a of the first cushion 10, and the raw material of the foaming material is filled between the adjacent air bags 101 after foaming, and the second cushion 20 can be filled in the gap between the plurality of air bags 101 after the raw material of the foaming material is foamed and formed, and connected to the first cushion 10. The surface of the second cushion 20 in contact with the first surface 10a is configured as a fourth surface 20b, and the surface of the air bag 101 away from the first cushion 10 and higher than the first cushion 10 is configured as a third surface 20a. The third surface 20a of the second cushion 20 is a surface facing the outside.

[0056] According to the present embodiment, compared with the first embodiment in which the user contacts the protector 100 in point contact with the air bag 101, in the present embodiment, the user contacts the protector 100 in surface contact with the second surface 10b of the first cushion 10, and the comfort of the user is improved. At the same time, when the protector 100 of the present embodiment is fixed to the prescribed part of the user, in the case of impact with a hard object, the first cushion 10 with small impact absorption capacity is more easily stressed and deformed first, and the stress from the stress concentration portion on the back of the air bag portion 1 is rapidly diffused to the periphery via the deformation of the air bags 101 of the air bag portion 1, more air bags 101 are compressed and deformed, at the same time, the air bag portion 1 presses the second cushion 20, and since the stress is rapidly diffused to the periphery from the stress concentration portion, the second cushion 20 is compressed with a large area, the cushioning effect can be increased, and at the same time, the first cushion 10 can be supported from collapsing and deforming even when the deformation amount of the first cushion 10 is large enough to make the first surface 10a close to the second surface 10b, and the user can be prevented from directly contacting the impacting hard object, and the risk of injury can be better reduced.

[0057] In addition, in the mode in which the plurality of air bags 101 are formed in a manner of protruding and standing towards both the first surface 10a and the second surface 10b, the second cushion 20 can be selectively provided in any one of the first surface 10a and the second surface 10b, and the cushioning effect can be increased, and the risk of injury can be better reduced.

[0058] (One example of a method of forming the composite cushion 30)

[0059] Regarding the method of forming the composite cushion 30 by foaming the raw material of the foaming material directly on the first surface 10a or the second surface 10b of the first cushion 10 to form the second cushion 20, the following is explained with reference to FIG. 9.

[0060] First, in step Sll, the first cushion 10 is prepared. This step can use an existing cushion, or the first cushion 10 can be made using an existing technique.

[0061] Next, a jig (not shown) that can be opened and closed to form an accommodation space inside when closed is prepared, and in step S12, the jig is opened and the first cushion 10 is fixed inside the jig. The first cushion 10 is positioned on one side of the accommodation space and one surface (the first surface 10a or the second surface 10b) of the first cushion 10 faces the other side of the accommodation space when the jig is closed. The jig can use an existing configuration.

[0062] Next, in step S13, a release agent is applied to the inner wall of the jig, and then an appropriate amount of the raw material of the foaming material is dropped into the other side of the accommodation space of the jig. At this time, the raw material of the foaming material does not fill the other side of the accommodation space of the jig.

[0063] After that, in step S14, the jig is closed and heated. When the jig is closed, one surface (the first surface 10a or the second surface 10b) of the first cushion 10 faces the other side of the accommodation space. When heated, the raw material of the foaming material is heated and expands to foam, and the foamed raw material of the foaming material comes into contact with one surface of the first cushion 10 and fills the remaining space of the accommodation space.

[0064] In step S15, after heating is stopped and the temperature decreases, the foamed raw material of the foaming material is foamed and formed into the second cushion 20, and the foamed raw material of the foaming material is tightly connected to one surface of the first cushion 10 after foaming. Thus, the composite cushion 30 is formed.

[0065] In step S16, the semi-finished product of the composite cushion 30 is taken out of the jig, and cutting and edging are performed to form a predetermined shape.

[0066] According to the above method, one way of forming the composite cushion 30 can be achieved, and the additional adhesive for connecting the second cushion 20 to the first cushion 10 can be omitted.

[0067] In addition, as shown in FIG. 10, the above method further comprises a step S17: between the step S15 and the step S16, or after the step S16, taking out the composite cushion 30, and applying a super wear-resistant polymer nano-coating or a protective layer of high-performance elastomer TPU film to the surface of the second cushion 20 away from the first cushion 10 (the third surface 20a or the fourth surface 20b). Thus, the service life of the composite cushion 30 is increased.

[0068] In addition, as shown in FIG. 11, instead of the step S17, the above method further comprises a step S18: before the step S12, laying a protective layer of high-performance elastomer TPU film on the inner surface of the clamp. The protective layer of high-performance elastomer TPU film can be pre-heated and deformed to fit the profile of the inner surface of the clamp. Then, the steps S12-S16 are sequentially performed, and the protective layer can be tightly connected to the surface of the second cushion 20 away from the first cushion 10 (the third surface 20a or the fourth surface 20b). According to the above method, one way of forming the composite cushion 30 with a protective layer is achieved, the service life of the composite cushion 30 is increased, and the cracking of the second cushion 20 is avoided. Moreover, the additional adhesive for connecting the second cushion 20 and the protective layer can be omitted.

[0069] Thus, according to the above method, the composite cushion 30 related to the first and second embodiments described above can be manufactured.

[0070]

Third Embodiment

[0071] In the above embodiments, it is mentioned that the first cushion 10 and the second cushion 20 are detachably connected through a connection structure not shown, such as a Velcro, a snap fastener, or magnetic attraction.

[0072] As shown in FIG. 13, in the protector 100b of the present embodiment, the first cushion 10 and the second cushion 20 in the composite cushion 30 are detachably connected through a connection structure. The connection structure is formed with a receiving portion 60, which detachably connects the first cushion 10 and the second cushion 20.

[0073] The receiving portion 60 is fixedly connected with the first cushion 10. The receiving portion 60 is mounted on one surface of the first cushion 10, and for the convenience of forming the receiving portion 60, the surface is preferably the second surface 10b without the air bag portion 1. One side of the receiving portion 60 has a receiving opening 61 communicating with the inside, and by inserting the second cushion 20 into the inside of the receiving portion 60 through the receiving opening 61, the second cushion 20 can be positioned, thereby forming the composite cushion 30.

[0074] Specifically, the accommodating portion 60 can be a pocket-shaped structure formed by sewing a portion of cloth along the edge or inner side of the edge of the first cushion 10, or the accommodating portion 60 formed in a pocket shape can be connected to one surface of the first cushion 10 by means of a magic tape, glue, high-temperature or ultrasonic-based welding, sewing, or the like.

[0075] The above merely provides specific examples of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which should be encompassed in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
