TECHNICAL FIELD
The present disclosure relates to a fabric architecture. More particularly, the present disclosure relates to a fabric architecture for different load-bearing applications.
BACKGROUND
Fabric is used for seating in automotive and other applications. Materials such as animal leather and synthetic leather (e.g., non-recyclable polyurethane synthesized using toxic isocyanates) may be used for such applications. However, leather may not be sustainable and has limited applicability in certain environments, for example, environments needing electrical functionality. In such cases, textiles may be preferred due to their feel and adaptability, for example, ability to handle higher heat generated during operation. Further, textiles may have additional features for automotive applications requiring occupancy sensing or heating by incorporating wires and fiber devices, and allowing moist vapor transport for breathability.
Current premium textiles that are used in automotive and other environments are made of fine wools (e.g., merino and cashmere) that have an excellent soft hand feel. However, these textiles are not durable enough to withstand abrasive loads caused by repeated passenger ingress and egress. Since the wool in such textiles is delicate, the textile can only be used in smaller areas that do not undergo repeated stress. Alternatively, durable textiles may be used in place of these premium textiles in other areas of the textile that are subject to high wear. However, these durable textiles typically do not look or feel as luxurious as natural fabrics, such as fine wool. One solution may include blending the fine wool with more durable yarns or fibers, but such resulting fabrics tend to be neither very durable nor very soft to the touch.
Hence, there is a need for an improved fabric that overcomes the aforementioned drawbacks.
SUMMARY
The fabric architecture according to the present disclosure introduces a load-bearing fabric that has a soft hand feel and can withstand varying loads applied thereon. The load-bearing fabric architecture includes a soft surface material and a support system. In an embodiment, the support system includes a frame and structural surface material that are connected to the soft surface material such that the soft surface material at least partially extends above the support system. The structural surface material are also connected to the frame. The support system provides support for loads that are applied on the soft surface material, such that on application of the load, the soft surface material moves downwards causing the structural surface material to contact with the load. The load-bearing fabric architecture has a soft hand feel due to the soft surface material that is made of wool. Further, the structural surface material, such as yarn, allows the fabric to withstand varying loads. Such load-bearing fabrics may be used in suspension textiles.
In an embodiment, the structural surface material are at least partially in contact with a supporting material, for example, foam, that lies beneath the structural surface material. The large cross section of the structural surface material provides an upward force when in contact with the supporting material, allowing varying loads to be applied on the load-bearing fabric. Such load-bearing fabrics may be used for seat cushion covers.
The load-bearing fabric architecture exposes the soft surface material upon contact with loads that are generally light, providing a soft hand feel. Further, the soft surface material sinks below the support system when higher loads are applied, causing the structural surface material to contact the load. Due to material properties of the structural surface material, the structural surface material are capable of withstanding compression and abrasion.

DETAILED DESCRIPTION
FIG. 1 illustrates a side profile of an exemplary vehicle 100 such as, for example, a passenger car, truck, sport utility vehicle, or van. The vehicle 100 includes a frame 102 that is supported by a set of wheels 104. The vehicle 100 includes a power source (not shown) configured to propel the vehicle 100.
Load-bearing fabric architectures are used at different locations within the vehicle 100, for example, suspension textiles, seat cushion covers, and so on. The present disclosure relates to various embodiments of the load-bearing fabric architecture that may be utilized for the suspension textile and the cushion covers respectively and will be explained in connection with FIGS. 2 to 19. It should be noted that the description provided in this section is equally applicable to any type of seating application for example, furniture and airplane seats, and is not limited to that described herein.
FIGS. 2 and 3 illustrate cross-sectional views of the load-bearing fabric architecture 200 when different loads are applied thereon. Referring to FIGS. 2 and 3, the load-bearing fabric architecture 200 includes a soft surface material 202 and a support system 204. The support system 204 includes a frame 206 and structural surface material 208 connected thereto. The frame 206 is provided at two ends of the load-bearing fabric architecture 200. The soft surface material 202 is provided on the structural surface material 208 in such a manner that when no load is applied on the load-bearing fabric architecture 200, the soft surface material 202 is disposed partially above the structural surface material 208 of the support system 204. More particularly, the soft surface material 202 is provided in such a manner that the soft surface material 202 extends above and goes through a mesh type large cross-section of the structural surface material 208 and is flush or proud of the structural surface material 208.
When no load is applied on the load-bearing fabric architecture 200, the soft surface material 202 that extends above a top surface of the structural surface material 208 presents itself for contact. The soft surface material 202 may include wool (e.g., cashmere or merino) or any other soft elastomer and has a soft hand feel. The structural surface material 208 provide strength and structural stability to the load-bearing fabric architecture 200. The structural surface material 208 may include yarn, foam, lattice structure, or any other suitable solid material. The frame 206 may be made of any suitable material such a wood, metal, plastic, and so on. The structural surface material 208 increase a load bearing capacity of the load-bearing fabric architecture 200.
When relatively light loads are applied on the load-bearing fabric architecture 200, as shown in FIG. 2, the light load comes in contact with the soft surface material 202 that lends the soft feel. The light load applies a downward force on the load-bearing fabric architecture 200 and causes some portion of the soft surface material 202 to get pushed inwards and into the mesh type structure of the structural surface material 208. The mesh type cross-section of the structural surface material 208 allows the soft surface material 202 to sink into and in some cases, may extend beyond a bottom surface of the structural surface material 208. The frame 206 and the structural surface material 208 that are connected to the frame 206 provide an upward force for sustaining the light load that is applied on the load-bearing fabric architecture 200.
When heavier loads are applied on the load-bearing fabric architecture 200, as shown in FIG. 3, the heavy load applies the downward force on the load-bearing fabric architecture 200. The heavy load in turn causes the soft surface material 202 to sink into and get pushed behind the structural surface material 208. Further, the heavy load contacts the structural surface material 208, causing the support system 204 to hold a majority of the load and transfer forces to the frame 206. The combination of the structural surface material 208 and the frame 206 provide support to the soft surface material 202, allowing the load-bearing fabric architecture 200 to withstand heavy load.
FIGS. 4 and 5 illustrate an embodiment of the load-bearing fabric architecture 400 in which the soft surface material 402 is attached to the structural surface material 408 of the support system 404 in such a manner that isolated or partially-interconnected islands of the soft surface material 402 extend above the top surface of the structural surface material 408 when light or no load is applied. As shown in FIG. 4, when light loads are applied on the load-bearing fabric architecture 400, the light load comes in contact with the soft surface material 402. When heavy loads are applied on the load-bearing fabric architecture 400, as shown in FIG. 5, the soft surface material 402 sinks into the structural surface material 408 of the support system 404 and the structural surface material 408 contact the heavy load. Further, the frame 406 and the structural surface material 408 provide support for the heavy load. The load-bearing fabric architectures described in connection with FIGS. 2 to 5 can be used in the suspension textiles of the vehicle 100. These load-bearing fabric architectures can be made using computerized weaving or three-dimensional knitting techniques.
FIGS. 6 and 7 illustrate cross sectional views of another load-bearing fabric architecture 600. The load-bearing fabric architecture 600 includes the soft surface material 602. The soft surface material 602 is in contact with the support system 604. The support system 604 includes a supporting material 606 and the structural surface material 608 connected to and lie above the supporting material 606. The supporting material 606 lies beneath the structural surface material 608 and extends substantially parallel to the load-bearing fabric architecture 600.
The isolated islands of the soft surface material 602 are provided on top of a bed of the structural surface material and adjacent to respective isolated islands of the structural surface material 608 in such a manner that when no load is applied on the load-bearing fabric architecture 600, the soft surface material 602 lies at least partially above the structural surface material 608 of the support system 604. More particularly, the soft surface material 602 is provided in such a manner that the soft surface material 602 is disposed above the structural surface material 608 and may be either flush or proud of the structural surface material 608.
When no load is applied on the load-bearing architecture 600, the soft surface material 602 presents itself for contact. The soft surface material 602 may include wool (e.g., cashmere or merino) and has a soft hand feel. The structural surface material 608 provide strength and structural stability to the load-bearing fabric architecture 600. The structural surface material 608 may include yarn, foam, lattice structure, or any other suitable solid material. The supporting material 606 may include foam or any suitable material for forming the cushion. The structural surface material 608 increase a capacity of the load-bearing fabric architecture 600 to withstand loads while reducing wear on the soft surface material 602.
When relatively light loads are applied on the load-bearing fabric architecture 600, as shown in FIG. 6, the light load comes in contact with the soft surface material 602 that lends the soft feel. The light load applies the downward force on the load-bearing fabric architecture 600 and causes the soft surface material 602 to get pushed downwards and towards the supporting material 606. The structural surface material 608 and/or the supporting material 606 provide the upward force for sustaining the light load.
When heavier loads are applied on the load-bearing fabric architecture 600, as shown in FIG. 7, the heavy load applies the downward force on the load-bearing fabric architecture 600. The heavy load in turn causes the soft surface material 602 to sinks into the structural surface material 608 and the supporting material 606. Further, the heavy load contacts the structural surface material 608, causing the support system 604 to hold a majority of the load, transferring forces to the supporting material 606 that lies beneath the structural surface material 608. The combination of the structural surface material 608 and the supporting material 606 provide support to the soft surface material 602, allowing the load-bearing fabric architecture 600 to withstand the heavy load. FIGS. 8 to 19 illustrate various embodiments of the load-bearing fabric architecture that can be used for the cushion covers of the vehicle 100.

It should be noted that the islands may appear isolated in a given cross-section, but these islands may in fact be connected for example, below the structural surface material 808 or elsewhere out-of-plane from the illustrated cross-section. Further, a rigid backing is present under the islands of the soft surface material 802 to spread the load more evenly underneath the backing. As shown in FIG. 8, when light loads are applied on the load-bearing fabric architecture 800, the light load comes in contact with the soft surface material 802. When heavy loads are applied on the load-bearing fabric architecture 800, as shown in FIG. 9, the soft surface material 802 sinks into the supporting material 806 of the support system 804 and the structural surface material 808 contact the heavy load.

As shown in FIG. 16, when light loads are applied on the load-bearing fabric architecture 1600, the light load comes in contact with the soft surface material 1602. When heavy loads are applied on the load-bearing fabric architecture 1600, as shown in FIG. 17, the soft surface material 1602 sinks into the structural surface material 1608, causing the structural surface material 1608 to contact the heavy load.
