Abstract

A puffer jacket configured to provide improved temperature regulation through graduated venting. In one embodiment, the jacket includes a back panel with baffles and insulation arranged to provide reduced insulation and increased venting of heat and humidity toward the center of the back. The back panel may include an alternating arrangement of insulation baffles (containing insulation) and vent baffles (free of insulation). The insulation baffles and vent baffles may be formed by joining inner and outer layers of fabric with laterally extending lines of stitching. The lines of stitching may follow paths selected to progressively change the relative size of the vent baffles and the insulation baffles toward the center of the back. For example, the lines of stitching may give the insulation baffles a somewhat hourglass shape shortening toward the center of the back resulting in increasingly greater venting of heat and humidity toward the center of the back.

First claim

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. An item of outerwear comprising:
a front panel and a back panel, the back panel having:
an outer layer of fabric;
an inner layer of fabric; and
a plurality of lines of stitching extending across the outer layer of fabric and the inner layer of fabric, the plurality of lines of stitching joining the outer layer of fabric and the inner layer of fabric to define a plurality of baffles, a first plurality of the baffles including insulation to form a plurality of insulation baffles, a second plurality of the baffles being free of insulation to form a plurality of vent baffles;
wherein the plurality of insulation baffles and the plurality of vent baffles are arranged side-by-side in a single layer of baffles;
wherein the back panel has a central portion extending vertically along a midline of the back panel; and
wherein the plurality of lines of stitching defining the plurality of baffles each follow a graduated lateral profile such that the plurality of insulation baffles each decrease in height toward the central portion, and the plurality of vent baffles each increase in height toward the central portion, such that the back panel has a graduated venting profile corresponding to the graduated lateral profile of the plurality of lines of stitching, the graduated venting profile including increased venting at the central portion and decreased venting away from the central portion.

2. The item of outerwear of claim 1 wherein the plurality of lines of stitching define alternating insulation baffles and vent baffles.

3. The item of outerwear of claim 2 wherein each insulation baffle is defined by an adjacent pair of the lines of stitching, the adjacent pair of the lines of stitching undulating toward one another toward the central portion of the back panel.

4. The item of outerwear of claim 3 wherein each vent baffle is defined by the lines of stitching of adjacent insulation baffles.

5. The item of outerwear of claim 4 wherein each insulation baffle has a generally hourglass shape with a narrow region toward the central portion of the back panel.

6. The item of outerwear of claim 1 wherein the plurality of vent baffles each increase in height along two opposing directions extending laterally inwardly toward the central portion of the back panel.

7. The item of outerwear of claim 6 wherein the plurality of insulation baffles each decrease in height along the two opposing directions extending laterally inwardly toward the central portion of the back panel.

8. The item of outerwear of claim 6 wherein the plurality of vent baffles each have a maximum height at the central portion of the back panel and a decreasing height in two opposing lateral directions extending away from the central portion of the back panel.

9. The item of outerwear of claim 6 wherein:
the back panel has a width, the plurality of baffles extending laterally across the width of the back panel.

10. The item of outerwear of claim 1 wherein:
the plurality of lines of stitching define alternating insulation baffles and vent baffles; and
each insulation baffle is defined by an adjacent pair of the lines of stitching, the adjacent pair of the lines of stitching undulating toward one another toward the lateral center of the back panel to concurrently decrease the height of the insulation baffles and increase the height of the vent baffles.

11. An item of outerwear comprising:
a plurality of panels joined in a shape configured to clothe at least a portion of a wearer's upper body, the plurality of panels including a back panel positioned to cover at least a portion of a back of the wearer; the back panel including a central portion extending vertically along a midline of the back panel; and
wherein the back panel includes an inner layer, an outer layer, and a plurality of laterally extending lines of stitching, the lines of stitching joining the inner layer and the outer layer to define a plurality of laterally extending baffles, the plurality of laterally extending baffles including:
a plurality of insulation baffles, each of the plurality of insulation baffles defining an internal void with insulation disposed in each respective internal void; and
a plurality of vent baffles, each of the plurality of vent baffles defining an internal void, each internal void of the plurality of vent baffles being free of insulation;
wherein the plurality of insulation baffles and the plurality of vent baffles are arranged side-by-side in a single layer of baffles; and
wherein the plurality of lines of stitching defining the plurality of baffles each follow a graduated lateral profile, such that the plurality of vent baffles increase in height along two opposing directions extending laterally inwardly toward the central portion of the back panel, such that the back panel has a graduated venting profile corresponding to the graduated lateral profile of the plurality of lines of stitching, the graduated venting profile including increased venting at the central portion and decreased venting away from the central portion.

12. The item of outerwear of claim 11 wherein the plurality of insulation baffles and the plurality of vent baffles are arranged in an alternating pattern.

13. The item of outerwear of claim 12 wherein the plurality of insulation baffles each decrease in height toward the central portion.

14. The item of outerwear of claim 11 wherein each adjacent pair of the lines of stitching defines one of the plurality of insulation baffles or one of the plurality of vent baffles.

15. The item of outerwear of claim 14 wherein each adjacent pair of the lines of stitching undulates toward or away from one another toward the central portion of the back panel.

16. The item of outerwear of claim 15 wherein the insulation baffles and the vent baffles alternate in a regular repeating pattern over the entire height of the back panel.

17. The item of outerwear of claim 11 wherein:
the plurality of insulation baffles and the plurality of vent baffles alternate in a regular repeating pattern over the entire height of the back panel; and
the plurality of insulation baffles each increase in height along two opposing directions extending laterally outwardly from the central portion of the back panel, with the plurality of vent baffles each concurrently decreasing in height along the two opposing directions extending laterally outwardly from the central portion of the back panel.
