Description

Technical Field

[0001] The present disclosure generally relates to the technical field of automobile seats, and in particular to a drawstring fixing structure, a massage airbag assembly and an automobile seat. Background Art

[0002] As an important component of the seat massage function, the massage air bag is installed on the side of the seat foam close to the human body. The massage air bag and the seat foam are mostly fixed by bonding and hanging.

[0003] When using the adhesive type, the working performance of the massage air bag is greatly affected by the viscosity of the adhesive. Once the adhesive loses its viscosity, there is a risk of the massage air bag moving, resulting in the loss of the massage effect. At the same time, the adhesive massage air bag is also prone to abnormal noise from peeling glue during operation, which seriously affects the massage experience.

[0004] Reference Figure 1-2 When the hanging type is adopted, the working performance of the massage air bag is relatively stable, and the position of the massage air bag will basically not move. The conventional hanging structure is to weld one end of the drawstring to one side of the restraint plate, and connect the restraint plate and the seat foam close to the human body to achieve the hanging of the massage air bag. The disadvantage is that when the drawstring is under stress, the tension is concentrated at the weld position, which can easily cause the drawstring to tear, thereby losing the fixing effect.

[0035] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0036] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] Example 1

[0038] Please refer to Figure 3-Figure 11 The present embodiment provides a drawstring fixing structure for fixing the massage airbag 3 through the through hole 2 on the seat foam 1, wherein the through hole 2 connects the A surface 4 close to the human body and the B surface 5 away from the human body of the seat foam 1, including:

[0039] A restraining piece 6, the restraining piece 6 comprises a rigid fixing portion 10 and a flexible connecting portion 11, a mounting surface 7 is provided on one side of the rigid fixing portion 10, the mounting surface 7 is provided with a mounting position 8, and the flexible connecting portion 11 is provided on the mounting position 8;

[0040] A drawstring 9, one end of which is connected to the flexible connection portion 11, and the other end of which is used to connect to the massage airbag 3;

[0041] When the mounting surface 7 is parallel to the drawstring 9 , the restraining sheet 6 can pass through the through hole 2 ; when the mounting surface 7 fits the B surface 5 , the drawstring 9 hangs the massage airbag 3 on the A surface 4 .

[0042] refer to Figure 1 and Figure 2 It should be noted that the conventional hanging structure for installing the massage airbag 3 is composed of a constraint sheet 6 and a drawstring 9. The conventional constraint sheet 6 is a single-sided type, and both sides of the constraint sheet 6 are flat structures. One end of the drawstring 9 is bent to be parallel to the surface of the constraint sheet 6 and welded to the surface of the constraint sheet 6. In this connection method, when the drawstring 9 is stressed, the tension is concentrated at the weld position between the drawstring 9 and the constraint sheet 6, such as Figure 2 At position a in the figure, when the force is too great, the drawstring 9 may be easily torn at the weld position, causing the drawstring 9 to be disconnected from the restraining piece 6, thereby losing the fixing effect on the massage airbag 3.

[0043] refer to Figure 3-Figure 6The drawstring fixing structure provided in this embodiment is also composed of a constraint sheet 6 and a drawstring 9, and the constraint sheet 6 is composed of the rigid fixing portion 10 and the flexible connection portion 11, and the rigid fixing portion 10 and the flexible connection portion 11 are an integrated structure, and both sides of the rigid fixing portion 10 are planar structures, one side of which forms the mounting surface 7, and the mounting position 8 is arranged at a position on the mounting surface 7 close to the center of the mounting surface 7, and the flexible connection portion 11 is installed on the mounting position 8; the drawstring 9 is a flexible belt, one end of the drawstring 9 is connected to the massage airbag 3, and the other end is connected to the flexible connection portion 11. When the drawstring 9 is subjected to tension, the tension is concentrated on the flexible connection portion 11, and the rigid fixing portion 10 and the flexible connection portion 11 are an integrated structure, so that the connection between the drawstring 9 and the constraint sheet 6 is more secure than the traditional hanging structure, avoiding the tearing of the drawstring 9 at the connection position; because the drawstring 9 is a flexible belt, the constraint sheet 6 can rotate relative to the drawstring 9 at the end of the drawstring 9.

[0044] refer to Figure 7-Figure 9 , Fig.11 When installing the massage airbag 3, connect the end of the drawstring 9 away from the flexible connection part 11 to the massage airbag 3, flip the constraint sheet 6 so that the installation surface 7 is parallel to the drawstring 9, and then pass the constraint sheet 6 and the drawstring 9 from the A surface 4 to the B surface 5 through the through hole 2; straighten the constraint sheet 6 so that the installation surface 7 fits on the B surface 5, and the constraint sheet 6 is snapped onto the B surface 5, and then cooperates with the drawstring 9 to hang and fix the massage airbag 3.

[0045] Furthermore, the flexible connection portion 11 can rotate relative to the rigid fixing portion 10 .

[0046] Specifically, refer to Figure 3-Figure 6 The rigid fixing part 10 is relatively hard to have a supporting effect, and the flexible connection part 11 is relatively soft and elastic relative to the rigid fixing part 10, so that the flexible connection part 11 can be bent, and then rotate relative to the rigid fixing part 10, and the rotation axis is equivalent to the mounting position 8. The angle between the rigid fixing part 10 and the flexible connection part 11 is changed by bending the flexible connection part 11, so that the mounting surface 7 can be adjusted to be parallel to the drawstring 9; when the drawstring 9 is subjected to tension, the tension is concentrated on the flexible connection part 11. Since the rigid fixing part 10 and the flexible connection part 11 are an integrated structure, the connection position is not prone to tearing when the tension is too large, thereby improving the strength of the connection.

[0047] Specifically, refer to Figure 3The sum of the length of the rigid fixing portion 10 along the X direction, the length of the flexible connecting portion 11 along the Z direction and the length of the drawstring 9 along the Z direction is less than the size of the through hole 2, so that when the mounting surface 7 is attached to the drawstring 9, the constraint sheet 6 can pass through the through hole 2 from the A surface 4 to the B surface 5. The length of the flexible connecting portion 11 along the X direction can be adjusted according to the connection requirements of the constraint sheet 6 and the massage airbag 3.

[0048] Furthermore, the restraining sheet 6 is made of plastic, nylon or silicone.

[0049] Specifically, the rigid fixing part 10 and the flexible connecting part 11 can be made of one or more of plastic, nylon, and silicone materials, and the rigid fixing part 10 and the flexible connecting part 11 can be made of the same material or different materials.

[0050] Furthermore, the rigid fixing portion 10 and the flexible connecting portion 11 are integrally formed, and the rigid fixing portion 10 and the flexible connecting portion 11 are in a T-shaped structure as a whole.

[0051] Specifically, the end of the flexible connection part 11 is injection molded in the rigid fixing part 10. In a natural state, the flexible connection part 11 is perpendicular to the mounting surface 7. The flexible connection part 11 and the rigid fixing part 10 form a T-shaped structure as a whole. The flexible connection part 11 has the elasticity so that after the constraint sheet 6 passes through the through hole 2, the rigid fixing part 10 can rebound to be perpendicular to the flexible connection part 11, and then the mounting surface 7 can be firmly matched with the through hole 2 when it is attached to the B surface. When the massage airbag 3 is not hung on the drawstring 9, the stability of the installation of the constraint sheet 6 can still be guaranteed, and the installation is more stable than that of the traditional hanging structure.

[0052] Furthermore, at least one connection hole 13 is formed on the flexible connection portion 11 so as to play a positioning role when the drawstring 9 is connected to the flexible connection portion 11 .

[0053] Specifically, the flexible connection portion 11 is provided with connection holes 13 penetrating through both sides thereof, and the connection holes 13 are used to position the connection between the drawstring 9 and the flexible connection portion 11 .

[0054] Furthermore, a welding surface is provided on one of the side walls of the flexible connection portion 11 which is perpendicular to the mounting surface 7 , and one end of the drawstring 9 away from the massage airbag 3 is fixed by being connected to the welding surface.

[0055] In this embodiment, the flexible connection portion 11 and the drawstring 9 are connected by welding. Specifically, since the flexible connection portion 11 is perpendicular to the mounting surface 7, Figure 3 and Figure 4 The upper side wall and the lower side wall of the flexible connection part 11 are also perpendicular to the mounting surface 7, and the welding surface is arranged on the lower side wall of the flexible connection part 11, that is, the welding surface is perpendicular to the mounting surface 7, and the end of the drawstring 9 is attached to the welding surface and welded to the welding surface; the mounting surface 7 is attached to the drawstring 9 by the mutual rotation between the rigid fixing part 10 and the flexible connection part 11. The connection hole 13 plays a role in welding positioning for the connection of the drawstring 9.

[0056] Furthermore, the length of the flexible connection portion 11 in a direction perpendicular to the mounting surface 7 is smaller than the length of the through hole 2 , and when the mounting surface 7 fits against the B surface 5 , the connection position between the flexible connection portion 11 and the drawstring 9 is placed inside the through hole 2 .

[0057] refer to Fig.11 In this embodiment, the length of the flexible connection portion 11 is less than the length of the through hole 2; when the mounting surface 7 is in contact with the B surface 5, the end of the flexible connection portion 11 away from the rigid fixing portion 10 is placed in the through hole 2, and then when the massage airbag 3 is fixed by the constraint sheet 6 and the drawstring 9, the connection position of the drawstring 9 and the constraint sheet 6 is located at Fig.11 At point b in the figure.

[0058] Furthermore, a plurality of reinforcing ribs 14 are arranged on the mounting surface 7 , and the reinforcing ribs 14 connect the rigid fixing portion 10 and the flexible connecting portion 11 , so as to increase the connection firmness between the rigid fixing portion 10 and the flexible connecting portion 11 , thereby improving the overall strength of the constraint plate 6 .

[0059] Example 2

[0060] Please refer to Fig.12 This embodiment provides another drawstring fixing structure. The same contents as those in the first embodiment are not repeated here. The difference is that:

[0061] A through hole is provided at one end of the drawstring 9 away from the massage airbag 3 , and the through hole provided on the drawstring 9 is fixed to the connection hole 13 provided on the flexible connection part 11 via a buckle 12 .

[0062] refer to Fig.12 In this embodiment, the flexible connection portion 11 and the drawstring 9 can also be connected via a buckle 12. Specifically, a through hole corresponding to the connection hole 13 is provided at the end of the drawstring 9; the buckle 12 is pin-shaped and penetrates the connection hole 13 and the through hole, thereby realizing the connection between the drawstring 9 and the flexible connection portion 11.

[0063] Example 3

[0064] Please refer to Fig.13 This embodiment provides another drawstring fixing structure. The same contents as those in Embodiment 1 are not repeated here. The difference lies in that the length of the flexible connection portion 11 in a direction perpendicular to the mounting surface 7 is greater than the length of the through hole 2. When the mounting surface 7 is in contact with the B surface 5, the connection position between the flexible connection portion 11 and the drawstring 9 is placed on the side of the seat foam 1 close to the A surface 4.

[0065] In this embodiment, the length of the flexible connection portion 11 is greater than the length of the through hole 2, and the drawstring 2 is connected to the end of the flexible connection portion 11 away from the rigid fixing portion 10; when the mounting surface 7 is in contact with the B surface 5, the end of the flexible connection portion 11 away from the rigid fixing portion 10 is placed on the side of the seat foam 1 close to the A surface 4, and then when the massage airbag 3 is fixed by the restraining sheet 6 and the drawstring 9, the connection position of the drawstring 9 and the restraining sheet 6 is located Fig.13 At c in the middle.

[0066] It should be noted that the connection mode between the drawstring 9 and the restraining sheet 6 and whether the connection is placed inside or outside the through hole 2 can be freely combined and are not limited to the above three embodiments. In actual use, the above embodiment 1 and embodiment 3 can be reasonably selected according to the convenience of installation.

[0067] Regardless of any of the above embodiments, when the mounting surface 7 is in contact with the B surface 5, the tension on the drawstring 9 is in the horizontal direction, and the points of action of the tension on the constraint plate 6 are concentrated on the flexible connection portion 11. Since the flexible connection portion 11 and the rigid fixing portion 10 are an integrated structure, the tearing force at the connection between the rigid fixing portion 10 and the flexible connection portion 11 is avoided when the drawstring 6 is subjected to tension, thereby reducing the degree of damage to the constraint plate 6, thereby achieving the purpose of extending the service life of the constraint plate 6 and making the massage airbag 3 more firmly hung.

[0068] Example 4

[0069] This embodiment provides a massage air bag set, including at least two drawstring fixing structures as described in Embodiments 1-3 and at least one massage air bag 3, wherein the massage air bag 3 is connected to one end of each drawstring 9 away from the restraining plate 6.

[0070] Specifically, the massage airbag group includes at least two drawstring fixing structures, and the two drawstring fixing structures can improve the stability of the massage airbag 3. The massage airbag 3 of the massage airbag group can be one or more. When there are more than one massage airbag 3, the multiple massage airbags 3 are connected in series or in parallel between the two drawstring fixing structures. Figure 7 In this embodiment, two massage airbag groups are installed on the seat foam 1, one of which includes two massage airbags 3 connected in series, and the other massage airbag group includes three massage airbags 3 connected in series. The massage airbag group provided in this embodiment can be more conveniently installed on the seat foam 1, has better hanging firmness and is not easily damaged at the hanging position.
