Abstract
Article, such as quilted construction, and methods of making the same are described. A quilted construction may comprise a first woven sheet, a second woven sheet, a series of stitching, a reinforcing body, and a thermally insulating filler. The first woven sheet may be coupled to the second woven sheet via a series of stitching to define one or more chambers. The reinforcing body may have a figure-eight form and may be disposed between the first woven sheet and second woven sheet such that a crossover of the figure-eight form is aligned with the series of stitching. The thermal insulating filler may be disposed within the one or more chambers.
Claims20
A construction comprising:
- a first layer;
- a second layer disposed adjacent the first layer such that the second layer is generally parallel to the first layer;
- a tubular insert disposed between the first layer and the second layer;
- and
- a plurality of stitches configured to join at least a portion of the first layer to at least a portion of the second layer, wherein at least a portion of the plurality of stitches pass through the tubular insert such that the tubular insert forms a curvilinear cross-sectional body, and wherein the plurality of stitches, the first and second layers, and the curvilinear cross-sectional body define a plurality of chambers between the first layer and the second layer;
- and
- a thermal insulation material disposed within the plurality of chambers.
A method of quilting comprising:
- affixing a tubular body to a first fabric layer of a plurality of fabric layers via a series of stitching, wherein the affixing the tubular body to the first layer forms a generally curvilinear cross-sectional body at the first layer;
- affixing a second fabric layer of the plurality of layers to the first layer and the generally curvilinear cross-sectional body via a second series of stitching wherein the second series of stitching is sewn through the first fabric layer, the second fabric layer and the formed generally curvilinear cross-sectional body, wherein the fabric layers, series of stitching, and generally figure-eight body define a volume;
- and
- joining at least a portion of a perimeter of the first layer and a perimeter of the second layer to form an enclosure, wherein the enclosure comprises the volume;
- and
- depositing a fill material at the enclosure such that at least a portion of the volume is filled.
A fabric structure comprising:
- a first woven sheet;
- a second woven sheet;
- a series of stitching affixing at least a portion of the first woven sheet to a portion of the second woven sheet and defining one or more chambers between the first woven sheet and the second woven sheet;
- a reinforcing body having a figure-eight form, wherein the reinforcing body is disposed between the first woven sheet and second woven sheet such that a crossover of the figure-eight form is aligned with the series of stitching;
- and
- a thermal insulating filler disposed within the one or more chambers.
