Description
Technical Field
[0001] This utility model relates to the field of bra technology, and in particular to a gore assembly for connecting bra cups. Background Technology
[0002] As a basic garment worn by women in their daily lives, the core function of a bra is not only to provide necessary support and shaping, but also to meet extremely high requirements for wearing comfort. In the structural design of a bra, the center gore (also known as the center bridge) is a key component. It is usually located on the lower inner side between two layers, moving upwards close to or connecting to the bottom of the layers, and downwards usually connected to the front center hook-and-eye closure (if present) or to the underband.
[0003] In current mainstream bra designs, the connection between the bottom of the outer fabric layer and the top of the center gore is almost universally achieved by direct stitching (i.e., "machine sewing"). Specifically, the edges of the outer fabric layer are aligned with the edges of the center gore fabric, and then sewn together using thread (a thin but strong thread, such as polyester thread). This connection method is technically mature, simple to execute, and inexpensive, and has therefore been widely used in the industry for decades.
[0004] However, this traditional stitching method reveals significant comfort and functional problems during actual wear, especially during prolonged wear or dynamic activities (such as exercise, walking, and bending over):
[0005] Hard friction and pressure: The effect of raised seam points: When the bra is close to the body, the seam stitches (especially the knots) at the connection points form a relatively "hard" raised structure, directly facing the most sensitive skin area at the top of the sternum (near the manubrium or xiphoid process). This localized, continuous pressure from these hard points can easily cause noticeable friction, itching, and even skin indentations or abrasions, leading to discomfort or even pain for the wearer.
[0006] Lack of cushioning: The material of the suture itself (such as polyester, nylon) and the way it is fixed and connected lack an effective elastic cushioning mechanism, which cannot absorb or alleviate the impact of small displacements caused by body movements on the connection point.
[0007] Rigid Pulling on the Bra Cup Underwire: Traditional stitching connections are rigid or quasi-rigid. When the outer layer shifts due to breast movement, this displacement is directly and rigidly transmitted through the stitches to the attached underwire. The underwire (or plastic cartilage) typically contains an underwire for support and shaping. This sudden pulling force forces the underwire at the bottom of the underwire to violently rise or fall against the center of the user's sternum (directly below the chest cavity), causing intense localized pressure and discomfort, as if a hard object is being poked into the chest. Therefore, a bra cup underwire assembly is proposed to address this problem. Utility Model Content
[0008] The purpose of this invention is to at least solve one of the aforementioned technical defects.
[0009] Therefore, one objective of this utility model is to provide a core component for connecting bra cups, in order to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.
[0010] To achieve the above objectives, one embodiment of the present invention provides a bra cup gore assembly, which includes a face layer, a back strap, and shoulder straps. The back strap is fixedly connected to the rear edge of the face layer, and the ends of the back strap can be fastened together with buckles.
[0011] A shoulder strap is fixedly connected between the top of the surface layer and the top of the back strap;
[0012] A heart-shaped part is fixedly connected between the surface layers. A flexible support strip is embedded at the connection between the bottom of the surface layer and the top of the heart-shaped part. The two ends of the flexible support strip are firmly bonded or hot-pressed to the bottom inner side of the surface layer and the top inner side of the heart-shaped part. The middle section of the flexible support strip is in the shape of a natural arc.
[0013] The connection between the outer layer and the heart-shaped part adopts a layered composite structure consisting of an outer layer, a middle layer, and an inner layer. The outer layer is the outer layer and the original fabric layer of the heart-shaped part, the middle layer is a cotton padding layer, and the inner layer is an ultra-fine mesh fabric layer.
[0014] Preferably, in any of the above embodiments, the surface layer is sewn to the back strap and shoulder strap, and the back strap and shoulder strap are elastic.
[0015] The above technical solution is adopted: the underwear structure consists of an outer layer, back straps, shoulder straps, a center gore, and a flexible support structure. The inner surface of the outer layer contacts the human chest, the ends of the back straps are hooked together and draped over the back of the human body, the shoulder straps hang on the shoulders of the human body, and the center gore is fixedly connected between the two outer layers.
[0016] Improvements to the heart-shaped component: A flexible support band replaces the traditional suture connection. A wide flexible support band (such as medical-grade silicone or high-elasticity TPU material) is embedded at the connection between the bottom of the surface layer and the top of the heart-shaped component, replacing the traditional sewing connection.
[0017] The support band is firmly bonded or heat-pressed to the bottom inner side of the outer layer and the top inner side of the center gore at both ends, with the middle section forming a natural overhanging arc, creating a "bridge-type cushioning structure." The connection between the outer layer and the center gore uses a layered composite structure: outer layer: original outer / center gore fabric; middle layer: lightweight memory foam padding (approximately 2-3mm thick, covering only the connection band area); inner layer: ultra-fine modal mesh. The component features dynamic cushioning: during body movement, the flexible support band can slightly stretch 5-8mm with chest movement, avoiding rigid pulling on the underwire at the center gore and reducing pressure on the sternum. The component also features pressure dispersion: the middle layer, i.e., the memory foam padding, distributes the pressure at the connection point throughout the entire support band area, avoiding single-point compression.
[0018] Improved comfort eliminates the friction of traditional sutures on the top of the sternum, reducing pressure on the center gore area during exercise. A flexible band conforms to the curve of the chest cavity, preventing the underwire from floating or pressing down. Enhanced structural stability is achieved through a three-layer structure at the connection between the center gore and the outer layer, increasing tensile strength and preventing dislocation of the outer layer from the center gore during strenuous exercise.
[0019] Preferably, in any of the above solutions, the buckle at the end of the shoulder strap is riveted to the shoulder strap.
[0020] The above technical solution comprises the following structural components: Outer layer: The inner surface contacts the chest, with an internal steel ring support structure. Back strap: An elastic band with hooks at both ends of its rear edge, wrapping around the back. Shoulder straps: Elastic bands connecting the top of the outer layer to the top of the back straps, suspending the body at the shoulders. Center gore: Located between the two outer layers, it has a triangular structure, with its top connecting to the bottom of the outer layer. Flexible support band: A 1-1.5cm wide medical-grade silicone or TPU band embedded at the connection between the bottom of the outer layer and the top of the center gore, replacing traditional sutures.
[0021] Three-layer composite structure: The connecting area is layered as follows: outer layer: surface layer / original fabric of the goat's heart (such as cotton, nylon); middle layer: lightweight memory foam padding, 2-3mm thick; inner layer: ultra-fine modal mesh fabric, directly against the skin.
[0022] Preferably, the flexible support strip is made of silicone or TPU, and the width of the flexible support strip is 1-1.5cm.
[0023] Processing method: Pre-fixation of flexible support strip: The two ends of the flexible support strip are fixed to the bottom inner side of the surface layer and the top inner side of the chicken heart layer respectively by hot pressing or bonding process. This causes the center section to naturally concave to form a suspended arc-shaped bridge (arc height ≈ 5mm).
[0024] Three-layer composite structure assembly: The connecting area is covered in sequence as follows: the original fabric of the surface layer / core as the outer layer; the memory foam padding piece as the middle layer; and the modal mesh fabric as the inner layer.
[0025] The three layers are bonded together using hot pressing or adhesive to cover the area of the flexible support strip.
[0026] Preferably, in any of the above embodiments, the outer layer is made of cotton fabric, and the thickness of the middle layer is 2-3 mm.
[0027] This component enhances performance through dual mechanical optimization: Dynamic cushioning mechanism: When the body moves (such as running), the chest displacement causes the surface layer to swing. The flexible support band absorbs the tensile force through elastic deformation (stretching 5-8mm), avoiding rigid transmission to the underwire and reducing sternal pressure by up to 30% (actual measured data).
[0028] Pressure dispersion mechanism: The memory foam padding in the middle layer expands evenly after being compressed, dispersing the pressure at the connection point to an area of ≥15mm² (compared to ≤3mm² for traditional seam points).
[0029] Preferably, the outer layer, the middle layer, and the inner layer are thermoformed or bonded together as a single unit.
[0030] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:
[0031] The bra cup's gore component uses a flexible support band instead of traditional stitching. A wide flexible support band (such as medical-grade silicone or high-elasticity TPU material) is embedded at the connection between the bottom of the surface layer and the top of the gore, replacing the traditional sewing connection.
[0032] The support band is firmly bonded or heat-pressed to the bottom inner side of the outer layer and the top inner side of the center gore at both ends, with the middle section forming a natural overhanging arc, creating a "bridge-type cushioning structure." The connection between the outer layer and the center gore uses a layered composite structure: outer layer: original outer / center gore fabric; middle layer: lightweight memory foam padding (approximately 2-3mm thick, covering only the connection band area); inner layer: ultra-fine modal mesh. The component features dynamic cushioning: during body movement, the flexible support band can slightly stretch 5-8mm with chest movement, avoiding rigid pulling on the underwire at the center gore and reducing pressure on the sternum. The component also features pressure dispersion: the middle layer, i.e., the memory foam padding, distributes the pressure at the connection point throughout the entire support band area, avoiding single-point compression.
[0033] Improved comfort eliminates the friction of traditional sutures on the top of the sternum, reducing pressure on the center gore area during exercise. A flexible band conforms to the curve of the chest cavity, preventing the underwire from floating or pressing down. Enhanced structural stability is achieved through a three-layer structure at the connection between the center gore and the outer layer, increasing tensile strength and preventing dislocation of the outer layer from the center gore during strenuous exercise.

[0043] A shoulder strap 3 is fixedly connected between the top of the outer layer 1 and the top of the shoulder strap 2;
[0044] A core 4 is fixedly connected between the surface layers 1. A flexible support strip 5 is embedded at the connection between the bottom of the surface layer 1 and the top of the core 4. The two ends of the flexible support strip 5 are firmly bonded or hot-pressed to the bottom inner side of the surface layer 1 and the top inner side of the core 4. The middle section of the flexible support strip 5 is in a natural arc shape.
[0045] The connection between the outer layer 1 and the core 4 adopts a 3-layer composite structure, consisting of an outer layer 6, a middle layer 7, and an inner layer 8. The outer layer 6 is the original fabric layer of the outer layer 1 and the core 4, the middle layer 7 is a cotton padding layer, and the inner layer 8 is an ultra-fine mesh fabric layer.
[0046] Example 1: The outer layer 1 is sewn together with the shoulder straps 2 and 3, which are elastic. The buckles at the ends of the shoulder straps 2 are riveted to them. The flexible support strap 5 is made of silicone or TPU and has a width of 1-1.5cm. The outer layer 6 is made of cotton fabric, and the middle layer 7 has a thickness of 2-3mm.

Shoulder Straps 3: Elastic bands connecting the top of Outer Layer 1 to the top of Back Straps 2, suspending the body at the shoulders. Heart-Shaped Support 4: Located between the two Outer Layers 1, forming a triangular structure, its top connecting to the bottom of Outer Layer 1. Flexible Support Strap 5: A 1-1.5cm wide medical-grade silicone or TPU strap, embedded at the connection between the bottom of Outer Layer 1 and the top of Heart-Shaped Support 4, replacing traditional sutures.
[0049] Three-layer composite structure: The connecting area is layered as follows: Outer layer 6: original fabric (such as cotton or nylon) for surface layer 1 / core 4; Middle layer 7: lightweight memory foam padding, 2-3mm thick; Inner layer 8: ultra-fine modal mesh fabric, directly against the skin.
[0050] The working principle of this utility model is as follows:
[0051] Processing method: Pre-fixing of flexible support strip 5: The two ends of the flexible support strip 5 are fixed to the bottom inner side of the surface layer 1 and the top inner side of the heart 4 respectively by hot pressing or bonding process. This makes the center section naturally concave to form a suspended arc-shaped bridge (arc height ≈ 5mm).
[0052] Three-layer composite structure assembly: The connecting area is covered in sequence as follows: the original fabric of the surface layer 1 / heart-shaped layer 4 as the outer layer 6; the memory foam padding piece as the middle layer 7; and the modal mesh fabric as the inner layer 8.
[0053] The three layers are bonded together using hot pressing or adhesives to cover five areas of the flexible support strip.
[0054] Working principle: This component improves performance through dual mechanical optimization: Dynamic buffering mechanism: When the human body moves (such as running), the chest displacement causes the surface layer 1 to swing. The flexible support belt 5 absorbs the tensile force through elastic deformation (stretching 5-8mm), avoiding rigid transmission to the heart-shaped steel ring 4, reducing sternal pressure by up to 30% (actual measurement data).
[0055] Pressure dispersion mechanism: The memory foam padding of the middle layer 7 is evenly extended after being squeezed, dispersing the pressure at the connection point to an area of ≥15mm² (the traditional seam is only ≤3mm²).
[0056] Compared with the prior art, the present invention has the following advantages:
[0057] The bra cup assembly uses a flexible support band 4 instead of traditional stitching. A wide flexible support band (such as medical-grade silicone or high-elasticity TPU material) is embedded at the connection between the bottom of the surface layer 1 and the top of the bra cup 4, replacing the traditional sewing connection.
[0058] The support band is firmly bonded or heat-pressed to the bottom inner side of the surface layer and the top inner side of the center gore at both ends, with the middle section forming a natural arc shape, creating a "bridge-type cushioning structure." The connection between the surface layer 1 and the center gore 4 uses a 3-layer composite structure: outer layer 6: the original fabric of surface layer 1 / center gore 4; middle layer 7: lightweight memory foam padding (approximately 2-3mm thick, covering only the connecting band area); inner layer 8: ultra-fine modal mesh. The component has dynamic cushioning performance: during body movement, the flexible support band 5 can slightly stretch 5-8mm with chest displacement, avoiding rigid pulling on the underwire of the center gore 4 and reducing pressure on the sternum. The component also has pressure dispersion performance: the middle layer 7, i.e., the memory foam padding, distributes the pressure at the connection point to the entire support band area, avoiding single-point compression.
[0059] Improved comfort eliminates the friction of traditional sutures on the top of the sternum, reducing pressure on the center gore (Position 4) during exercise. A flexible band conforms to the curve of the chest cavity, preventing the underwire from floating or pressing down. Enhanced structural stability: the three-layer structure at the connection between the center gore (Position 4) and the outer layer (Position 1) increases the tensile strength of the connection, preventing dislocation of the outer layer (Position 1) from the center gore (Position 4) during strenuous exercise.
