Description

Technical Field

[0001] The utility model relates to a scrim, and more particularly to a scrim capable of preventing deviation and separation when a safety airbag is deployed. Background Art

[0002] Airbags, specifically, passenger airbags (PABs), are used to minimize the injury of passengers in the event of a vehicle collision. The airbag is installed inside a crash pad, and when a door disposed on the side where the crash pad is located is opened, the crash pad is deployed to protect the passengers.

[0003] When the passenger airbag needs to be deployed, the door portion of the crash pad is opened toward the passenger and the airbag is deployed. In this case, because there is a risk that the door portion of the airbag may be damaged by the deployment force of the airbag, a fabric piece is provided to prevent the door portion from being damaged and to prevent the door portion from being deflected toward the passenger. The fabric piece has a mesh structure in the form of a fabric sheet and is insert-molded so as to hold the door portion of the airbag when the airbag is deployed.

[0004] The conventional fabric piece is designed to be offset and detached from the airbag ramp wall to compensate for the insufficient length of the airbag door. Therefore, the length of separation and offset of the fabric piece may be extended by the high pressure of the inflator, and in some cases, the fabric piece may be completely offset. In particular, in the case of an electric vehicle, since the interior space of the vehicle becomes more spacious and the airbag covering this space becomes larger, a high-pressure inflator may be used, which may lead to a phenomenon that the fabric piece is completely detached or offset when the conventional fabric piece is used.

[0005] When the fabric member is fully deflected and detached, damage to the airbag door may occur, and when the airbag door is deflected toward the passenger, the passenger may be injured. Therefore, there is a need for a fabric member that can stretch and stably hold the door portion of the airbag under tension without deflecting and detaching. Utility Model Content

[0045] An embodiment of the utility model aims to provide a fabric piece, which can stably hold the safety airbag door so that it does not deviate and separate when the safety airbag is deployed.

[0046] Hereinafter, an embodiment of a fabric piece according to the present invention will be described in detail with reference to the accompanying drawings. In the description of the exemplary embodiments with reference to the accompanying drawings, the same or corresponding constituent elements are assigned the same reference numerals regardless of any figure numerals, and their repeated description will be omitted.

[0047] Figure 1 is a view showing a fabric piece according to one embodiment of the present invention, and Figure 2 2 is a view showing a hinge portion of a fabric piece according to an embodiment of the present invention.

[0048] Reference Figure 1 and Figure 2The fabric piece 100 according to one embodiment of the present invention may be disposed on the inner side of a crash pad formed with an airbag door opened when the airbag is deployed and an airbag ramp 300 , and may be formed in a mesh form.

[0049] The fabric piece 100 may include a body portion 120 disposed on the airbag door, a bent portion 110 disposed on the wall surface of the airbag ramp 300 , and a hinge portion 130 connecting the body portion 120 and the bent portion 110 , and the hinge portion 130 may be at least partially folded to be located in the airbag ramp 300 .

[0050] When the passenger airbag is deployed, the airbag door of the crash pad opens toward the passenger and the windshield, and the fabric piece 100 holds the airbag door and prevents the airbag door from shifting and detaching inside the vehicle. The conventional fabric piece 100 is formed in a mesh form, and even when a force is applied, the amount of stretching is not large due to the low elongation of the material. Therefore, the fabric piece 100 can hold the airbag door by compensating for the insufficient length of the airbag door when the fabric piece is torn or separated.

[0051] However, there is a risk that the airbag door may detach and be thrown into the interior of the vehicle when the fabric piece 100 is completely detached or offset. In particular, in the case of electric vehicles or autonomous vehicles currently being developed, the space that the airbag needs to cover becomes larger, while also requiring protection of a larger space inside the vehicle. In order to stably operate the airbag, an inflator may be used to deploy the airbag at a higher pressure than a conventional inflator, and in this case, there is a risk that a structure such as the airbag door may detach and be thrown into the interior of the vehicle. Therefore, the fabric piece 100 is required to stably hold the airbag door without causing damage such as detachment and offset when the airbag is deployed.

[0052] In the case of the present embodiment, an example of the fabric piece 100 having both ends bent is the fabric piece 100 provided on the inner side of the airbag ramp 300. The fabric piece 100 may be provided on the inner side of the airbag ramp 300, and may include a body portion 120 provided on the airbag door and a bent portion 110 provided on the wall of the airbag ramp 300, the body portion 120 and the bent portion 110 being connected by a hinge portion 130. Although the conventional hinge portion 130 is only used to connect the body portion 120 and the bent portion 110 without any specific configuration, in the present embodiment, the length of the hinge portion 130 is extended and the extended portion is folded so that the fabric piece 100 can be arranged on the inner side of the crash pad and the airbag ramp 300 in a folded state.

[0053] The hinge portion 130 may be formed as a separate piece and provided on the fabric piece 100. Alternatively, the conventional fabric piece 100 may have a folded portion become the hinge portion 130 by extending the length of the hinge portion 130 and the extended portion may be folded. There is no limitation on the folding manner of the hinge portion 130 as long as the folded portion can be easily unfolded to hold the airbag door when the airbag is deployed.

[0054] like Figure 1 and Figure 2 As shown, the hinge portion 130 may be arranged so that the folded portion of the hinge portion 130 is folded between the end of the body portion 120 and the end of the bent portion 110. The hinge portion 130 may be folded in a zigzag manner so that the folded portion is disposed on the inner side of the airbag ramp 300.

[0055] Figure 3 is a view showing an unfolded state of a fabric piece according to another embodiment of the present invention.

[0056] Reference Figure 3 , the hinge portion 130 and a marking portion 131 may be formed on the fabric piece 100, the marking portion marking the line along which the hinge portion 130 is folded. The marking portion 131 may be marked with a marking tool such as a masking tape or a pen. The marking portion 131 may mark an area corresponding to the hinge portion 130 and may mark the line along which the hinge portion 130 is folded. Figure 3 In the case of Figure 2 Folded as shown, with the dashed lines folded inwardly and the dot-dash lines folded to face each other.

[0057] Figure 4 is a view showing a hinged portion of a fabric piece according to another embodiment of the present invention, Figure 5 is a view showing a hinged portion of a fabric piece according to another embodiment of the present invention, Figure 6 2 is a view showing a fixing structure according to still another embodiment of the present invention.

[0058] Reference Figure 4 and Figure 5 The hinge portion 130 may be fixed in the folded state by a fixing member 230, or may be bonded by a double-sided tape 210, an adhesive 220, etc. to maintain the folded state.

[0059] exist Figure 4In the case of the hinge portion 130, the double-sided tape 210 or the adhesive 220 is applied between the folded surfaces of the hinge portion 130 to keep the folded portion in the folded state. Since the fabric piece 100 is a fabric material having a mesh form, the fabric piece 100 is restored to the original state to a certain extent after being folded and it is difficult to maintain a completely folded state. Adhesion may be required when the hinge portion 130 is fixed by the double-sided tape 210, the adhesive 220, etc., so that when the hinge portion 130 is unfolded with the deployment of the airbag, the folded portion can be easily unfolded by the force of unfolding the airbag door without tearing the fabric piece.

[0060] Figure 5 The state in which the folded portion of the hinge portion 130 is fixed by the fixing member 230 is shown. The fixing member 230 may fix the hinge portion 130 in a stapled form and may fix the hinge portion 130 by thread sewing. There is no limitation on the material and size of the fixing member 230 as long as the fixing member 230 is spread apart and the hinge portion 130 can be easily deployed when the airbag is deployed.

[0061] Figure 6 One side of the fixing member 230 in the embodiment has an open shape, the folded hinge part 130 is assembled into the open surface of the open shape, and the ends of both sides provided in the open surface can be bent to maintain the folded hinge part 130 and fix the hinge part 130. In an embodiment, the folded portion of the hinge part 130 can be provided in an open space defined by the open shape. The shape and material of the fixing member 230 are not limited as long as the hinge part 130 can maintain the folded state and is easy to unfold when the airbag is deployed. According to the length of the hinge part 130 and the way the hinge part 130 is folded, a plurality of fixing members 230 can be applied.

[0062] Figure 7 1 is a view showing a state in which a fabric piece according to an embodiment of the present invention is unfolded.

[0063] refer to Figure 7 , it can be seen that the fabric piece 100 is disposed on the inner side of the airbag ramp 300. When the airbag is deployed, the airbag door opens toward the interior of the vehicle. In this case, as the airbag door is opened, the length of the portion corresponding to the hinge of the airbag door will increase, and the hinge portion 130 in the folded state can be unfolded to cover the increased length. The hinge portion 130 can be unfolded to stably hold the airbag door so that the airbag door does not detach and deviate to the interior of the vehicle, thereby protecting the passengers.

[0064] Figure 8 is a flow chart illustrating a method of manufacturing a fabric piece.

[0065] refer to Figure 8 The method for manufacturing the fabric piece 100 may include setting a mesh sheet (step S10), folding a hinge portion (step S30) and preforming a mesh sheet (step S50), wherein the fabric piece 100 includes: a main body portion 120, which is set on an airbag door that opens when the airbag is deployed; a bent portion 110, which is set on a wall surface of an airbag ramp 300; and a hinge portion 130, which connects the main body portion 120 and the bent portion 110.

[0066] Since the fabric piece 100 is formed in a mesh form, a mesh sheet may be provided first. The provided mesh sheet may be cut to fit the size of the fabric piece 100 to be manufactured. Therefore, the mesh sheet may be cut into a preset size before providing the mesh sheet (step S10).

[0067] After the mesh sheet is set, folding the hinge portion (step S30) is performed. The hinge portion 130 can be manually folded by the operator, and folding the hinge portion (step S30) can include marking a folding line of the hinge portion (step S20), folding the hinge portion (step S30), and fixing the folded hinge portion (step S40). Marking the folding line of the hinge portion (step S20) can be performed by marking the hinge portion 130 and the line at which the hinge portion 130 is to be folded on the unfolded mesh sheet using masking tape or a pen. After marking the folding line, the operator can fold the hinge portion 130 along the folding line.

[0068] After folding the hinge part 130, the hinge part 130 needs to be kept in the folded state, and for this purpose, the hinge part 130 needs to be fixed in the folded state. Therefore, fixing the folded hinge part (step S40) may be performed. The folded hinge part 130 may be sutured with a thread or fixed with a separate fixing member 230. Without using a separate tool, the folded hinge part 130 may be fixed by applying a double-sided tape 210 or an adhesive 220 to the folded part to adhere the folded side.

[0069] After folding the hinge portion 130 and fixing the folded hinge portion 130, the mesh sheet may be preformed. The shape of the fabric piece 100 to be insert molded may be formed by preforming, and the fabric piece 100 may be formed into various shapes by preforming, such as a shape having a bent bent portion 110 or a straight shape. The fabric piece 100 may be preformed into a preset shape based on the type of vehicle to which the fabric piece is applied, etc.

[0070] The preforming process may be an operation in which the mesh sheet is press-molded. Since the mesh sheet is easily deformed by heating, the mesh sheet can be heated and pressed by a mold to form the mesh sheet into a preset shape.

[0071] According to one embodiment of the present invention, a folded hinge portion is formed in a fabric piece provided on the inner side of the crash pad and on the airbag ramp, and the folded hinge portion can be unfolded when the airbag is deployed and keep the airbag door from being disengaged or deflected.
