Description

Technical Field

[0001] This invention relates to safety devices for vehicles, and more specifically, to a method for weaving seat belt webbing and seat belt webbing itself. Background Technology

[0002] Vehicle seat belts include webbing, which is typically formed from fabric through weaving. In the event of rapid vehicle deceleration and the corresponding force acting on the vehicle occupants, the seat belts are used to secure the occupants to their seats. The seat belts are part of a safety device that includes a pretensioner that can tension the webbing in the event of an impending collision. This ensures that vehicle occupants are secured to their seats via the seat belts, for example, in the initial stages of a collision.

[0003] The seatbelt comes into contact with the body of the passenger seated in the seat. To meet the passenger's heating requirements, heating elements may be incorporated into the seatbelt; alternatively, lighting elements may be incorporated to facilitate the passenger's wearing of the seatbelt in dimly lit environments. Therefore, heating or lighting elements are typically woven into the seatbelt. However, weaving heating or lighting elements into the seatbelt makes it difficult to flexibly design their placement within the seatbelt.

[0004] Therefore, it is desirable to provide a seat belt webbing that can flexibly accommodate functional components. Summary of the Invention

[0005] The purpose of this invention is to provide a method for weaving seat belt webbing that allows for flexible placement of functional components, and a seat belt webbing itself.

[0006] One aspect of the present invention provides a method for weaving seat belt webbing, comprising the following steps:

[0007] Provide the first yarn, the second yarn, and the third yarn.

[0008] The first thread is extended in a first direction, and the second thread is extended in a second direction different from the first direction. The first thread and the second thread are then woven together to form a first layer and a second layer of the seatbelt webbing.

[0009] At the separation section between the first layer and the second layer, the third thread is woven into one of the first layer and the second layer, and a first section of the third thread is positioned between the first layer and the second layer, and a second section of the third thread protrudes from the outer surface of the seat belt webbing by a predetermined distance.

[0010] According to an embodiment of the invention, a fourth thread is further provided, at the separation section, such that the fourth thread extends from the outer side through the inner side in only one of the first layer and the second layer, and then returns to the outer side, so as to separate the first layer and the second layer from each other.

[0011] At the connection point between the first layer and the second layer, the fourth thread extends from the outer side of the first layer, passes through the inner sides of both the first layer and the second layer, the outer side of the second layer, and then returns to the outer side of the first layer, so that the first layer and the second layer are connected to each other.

[0012] According to an embodiment of the present invention, the separating section and the connecting section are alternately arranged in the width direction of the seat belt webbing.

[0013] According to an embodiment of the present invention, the first direction is defined as the length direction of the seat belt webbing, and the second direction is defined as the width direction of the seat belt webbing.

[0014] According to an embodiment of the present invention, both the third and fourth threads extend along the first direction.

[0015] According to an embodiment of the invention, a functional element is provided, which is fixed to the first or second segment of the third webbing, and then a force is applied to the second or first segment of the third webbing and the third webbing is pulled out from the seat belt webbing, such that the functional element is positioned between the first and second layers.

[0016] Another aspect of the present invention provides a seat belt webbing,

[0017] in,

[0018] The seat belt webbing is manufactured according to the aforementioned seat belt webbing weaving method, and includes a cavity defined by the first layer and the second layer at the separation section, wherein a functional element is disposed in the cavity.

[0019] According to an embodiment of the present invention, at the separation section, the fourth thread extends from its outer side through the inner side in only one of the first layer and the second layer, and then returns to the outer side again;

[0020] At the connection point between the first layer and the second layer, the fourth thread extends from the outer side of the first layer, passes through the inner sides of both the first layer and the second layer, the outer side of the second layer, and then returns to the outer side of the first layer.

[0021] According to an embodiment of the present invention, a plurality of the separating segments and a plurality of the connecting segments are provided, the separating segments and the connecting segments being arranged alternately in the width direction of the seat belt webbing to form a plurality of cavities.

[0022] According to an embodiment of the present invention, the functional component is configured as a webbing heating element or a webbing lighting element. Attached Figure Description

[0023] The features, advantages, and technical effects of exemplary embodiments of the present invention will now be described with reference to the accompanying drawings. In the drawings, the same symbols denote the same elements, wherein:

[0024] Figure 1 The seat belt webbing according to an embodiment of the present invention is shown schematically.

[0025] Figures 2-4 A method for weaving seat belt webbing according to an embodiment of the present invention is illustrated schematically. Detailed Implementation

[0026] The following description, in conjunction with the accompanying drawings, describes a method for weaving seatbelt webbing according to the present invention and specific embodiments of the seatbelt webbing. The detailed description and accompanying drawings are provided to exemplify the principles of the invention. The invention is not limited to the described preferred embodiments; the various embodiments described can be used individually or in any combination. The scope of protection of the invention is defined by the claims.

[0027] Furthermore, spatially related terms (such as "up," "down," "left," and "right") are used to describe the relative positional relationship between elements shown in the accompanying drawings and other elements. Therefore, spatially related terms can be applied to directions different from those shown in the accompanying drawings. Clearly, while all these spatially related terms refer to the directions shown in the accompanying drawings for ease of explanation, those skilled in the art will understand that directions different from those shown in the accompanying drawings can be used.

[0028] Figure 1 A seatbelt webbing according to an embodiment of the present invention is schematically shown. Reference is made below. Figure 1 The seat belt webbing according to an embodiment of the present invention is described.

[0029] like Figure 1As shown, the seatbelt webbing 10 includes a first layer 110 and a second layer 120, meaning the seatbelt webbing 10 has a double-layer structure, with the first layer 110 and the second layer 120 overlapping in the thickness direction of the seatbelt webbing 10. The first layer 110 and the second layer 120 are connected together in some sections and separated from each other in other sections. That is, the first layer 110 and the second layer 120 have a connecting section 101 and a separating section 102. Furthermore, at the separating section 102, the seatbelt webbing 10 includes a cavity 103 defined by the first layer 110 and the second layer 120, in which a functional element (not shown) can be disposed. It is understood that the cavity 103 includes a receiving space defined by an upper wall and a lower wall, and the upper wall and the lower wall of the cavity 103 are respectively part of the first layer 110 and the second layer 120. At the connecting section 101, the first layer 110 and the second layer 120 are connected together, thereby leaving no cavity between them. In one example, the functional component can be configured as a webbing heater; in another example, the functional component can be configured as a webbing light source. It should be noted that in... Figure 1 Functional components have not yet been introduced into the seat belt webbing 10 shown.

[0030] It should be noted that each of the first layer 110 and the second layer 120 is woven from the first yarn 11 and the second yarn 12, combined with... Figures 2-4 As shown, a first weft yarn 11 extends in a first direction, and a second weft yarn 12 extends in a second direction. The first direction is defined as the length direction of the seatbelt webbing 10, and the second direction is defined as the width direction of the seatbelt webbing 10. The first weft yarn 11 is generally referred to as a warp yarn, and the second weft yarn 12 is generally referred to as a weft yarn. The weft yarns extend transversely to the warp yarns and interweave with each other. Although the figure shows one weft yarn extending in the shed of two warp yarns, this is merely an example, and the seatbelt webbing of the present invention is not limited thereto. For example, two weft yarns may extend as one strand in the shed of two warp yarns, or one weft yarn may extend in the shed of two strands of warp yarns, and each warp yarn may consist of two warp yarns.

[0031] Continue to refer to Figure 1 The seatbelt webbing 10 also includes a third thread 13, which in this example also extends in the first direction. The third thread 13 has a segment positioned within the cavity 103. Figure 1 (not shown in the image) and the portion exposed on the outer surface of the seatbelt webbing 10 (i.e., Figure 1(The portion shown is the arc segment in the diagram). When it is necessary to introduce the functional component, the functional component can be fixed together with the third webbing 13, for example, by knotting. Then, force is applied to the portion of the third webbing 13 exposed on the outer surface of the seatbelt webbing 10, or force can be applied to the end of the third webbing 13 positioned in the cavity 103, causing the third webbing 13 to move along the length of the seatbelt webbing 10 until it is pulled away from the seatbelt webbing 13. At the same time, the functional component moves together with the third webbing 13 and enters the cavity 13. Furthermore, if necessary, some portions of the functional component can continue to move to the outer surface of the seatbelt webbing 10 after entering the cavity 13. In other words, the third webbing 13 acts as an introducer, which can introduce the functional component into the cavity 13 of the seatbelt webbing 10, and even guide the functional component to the outer surface in some cases. In this way, the functional component can be introduced into the predetermined position of the seatbelt webbing 10 in a flexible manner. Furthermore, in the above embodiments, the third webbing is described as extending in the first direction, but the seat belt webbing of the present invention is not limited thereto. For example, when the functional component needs to extend in the width direction of the seat belt webbing, the third webbing also needs to be positioned on the seat belt webbing in a manner that extends in the width direction. Alternatively, the third webbing can also be arranged on the seat belt webbing in other orientations as needed.

[0032] According to one embodiment of the present invention, such as Figure 3 As shown, the seatbelt webbing 10 includes four cavities 103 that extend continuously along the length of the seatbelt webbing 10 and span its entire length. In one example, the four cavities 103 include two cavities 103 located at the edge of the seatbelt webbing 10 in the width direction. For this purpose, the seatbelt webbing 10 includes four separating sections 102 and three connecting sections 101, which are alternately arranged in the width direction of the seatbelt webbing 10. In another example, none of the four cavities 103 are located at the edge of the seatbelt webbing 10 in the width direction. For this purpose, the seatbelt webbing 10 includes four separating sections 102 and five connecting sections 101, which are alternately arranged in the width direction of the seatbelt webbing 10.

[0033] Figures 2-4 A method for weaving seatbelt webbing according to an embodiment of the present invention is illustrated schematically. Reference is made below. Figures 2-4 A method for weaving seat belt webbing according to an embodiment of the present invention is described.

[0034] like Figures 2-4 As shown, the method for weaving the seat belt webbing of the present invention includes the following steps:

[0035] Provides first yarn 11, second yarn 12 and third yarn 13,

[0036] The first weft thread 11 extends in a first direction (as previously described, the length direction of the seat belt webbing 10), and the second weft thread 12 extends in a second direction (as previously described, the width direction of the seat belt webbing 10). The first weft thread 11 and the second weft thread 12 are then woven together to form a first layer 110 and a second layer 120 of the seat belt webbing 10. It should be noted that the first layer 110 and the second layer 120 can be manufactured separately and formed as two separate layers, then overlapped in the thickness direction and their edges secured by, for example, stitching; alternatively, the first layer 110 and the second layer 120 can be formed as a single layer, then folded and secured at the edges by, for example, stitching, to form a two-layer structure. Both of these methods are included in the seat belt webbing weaving method of the present invention.

[0037] As previously described, some segments of the first layer 110 and the second layer 120 are separated from each other, while other segments of both are connected to each other. Therefore, positions for forming separate segments and positions for forming connecting segments are provided on the first layer 110 and the second layer 120. For ease of description, the positions for forming separate segments are also referred to as separate segments, and the positions for forming connecting segments are also referred to as connecting segments. The following description is based on this definition.

[0038] At the separation section 102 (the location where the separation section will be formed) between the first layer 110 and the second layer 120, the third thread 13 is woven into the first layer 110. Of course, this is just an example; the third thread 13 can also be woven into the second layer 120. Specifically, as... Figure 2 and Figure 3 As shown, the first segment 131 of the third webbing 13 is positioned between the first layer 110 and the second layer 120, and the second segment 132 of the third webbing 13 protrudes from the outer surface of the seatbelt webbing 10 by a predetermined distance. When a functional component needs to be introduced, it can be fixed to... Figure 2 Force is applied at either the left or right first section 131 of the third webbing 13, and then at the second section 132, to pull the third webbing 13 away from the seatbelt webbing 10. Alternatively, force is applied at the first section 131 where the functional element is not secured to pull the third webbing 13 away from the seatbelt webbing 10. Simultaneously, as the third webbing 13 is pulled away from the seatbelt webbing 10, the functional element is introduced into the cavity 103. Figure 2 As shown, the second segment 132 of the third weave 13 crosses eight second weaves 12, but this is just an example and the position and length of the second segment 132 can be chosen as needed.

[0039] To provide the connecting section 101, a fourth weaving thread 14 is also provided, such as Figure 2 As shown, both the fourth weave thread 14 and the third weave thread 13 extend along the first direction. Figure 2 and Figure 3 As shown, at the separation section 102 (the location where the separation section will be formed), the fourth webbing 14 extends from the outer side of the first layer 110 (or, of course, the second layer 120) through the inner side, and then returns to the outer side, so that the first layer 110 and the second layer 120 are separated from each other. It can be understood that the position where the fourth webbing 14 enters the inner side from the outer side of the first layer 110 is different from the position where it returns to the outer side; that is, along the length of the seatbelt webbing 10, multiple predetermined points are provided at intervals for the fourth webbing 14 to enter or exit the cavity 103. Furthermore, as... Figure 4 As shown, at the connecting section 101 (where the connecting section will be formed) of the first layer 110 and the second layer 120, the fourth webbing 14 extends from the outer side of the first layer 110, passes through the inner sides of both the first layer 110 and the second layer 120, and the outer side of the second layer 120, and then returns to the outer side of the first layer 110, thus connecting the first layer 110 and the second layer 120 to each other. Similarly, the position where the fourth webbing 14 enters the inner side of the first layer 110 from the outer side is different from the position where it returns to the outer side, and the position where it enters the outer side of the second layer 120 from the inner side is different from the position where it returns to the inner side. That is, along the length of the seatbelt webbing 10, multiple predetermined points are spaced apart on each of the first layer 110 and the second layer 120 for the fourth webbing 14 to enter or exit the cavity 103. In other words, the fourth webbing 14 extends in a wavy pattern in the direction of the seatbelt webbing 10. Figure 2 and Figure 3 As shown, the fourth thread 134 crosses two or three second threads 12 to enter or leave the cavity 103, but this is just an example, and the number of second threads between adjacent entry points of the fourth thread in each of the first and second layers can be selected as needed.

[0040] Therefore, in the weaving method of the seat belt webbing of the present invention, by setting a portion of the third thread to protrude from the outer surface of the seat belt webbing and positioning the remaining portion in the cavity of the seat belt webbing, the functional component can be introduced into the cavity of the seat belt webbing by pulling out the third thread. Thus, the position of the functional component can be designed conveniently and flexibly, and the functional component can be placed in the seat belt webbing in a flexible manner.

[0041] As mentioned above, although exemplary embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the specific embodiments described above, and the scope of protection of the present invention should be defined by the claims and their equivalents.
