Abstract

The application relates to a flame blocking venting trap (FBVT) adapted to vent a garment, the FBVT comprising a proximal layer; a central venting layer superposed to the proximal layer; and a distal layer superposed to the central venting layer. The the proximal layer is forming a first fold with the central venting layer and the central venting layer is forming a second fold with the distal layer to act as a flow restricting apparatus configured to prevent air and flames to get through the FBVT from the outside of the garment and allow air to get through the FBVT from the inside of the garment. A garment including one or many FBVT is encompassed by the present application.

Claims20

Dependent claims

A flame retardant protective garment having a vent for ventilation of a wearer, comprising:

(a) a flame retardant proximal fabric layer;
(b) a central venting layer connected to the proximal fabric layer by an internal fold;
and
(c) a flame retardant distal fabric layer connected to the central venting layer by an external fold;
(d) wherein the central venting layer comprises:
(i) a mesh portion that is made from a first flame retardant material, that is configured to allow a flow of air to pass therethrough, and that is located between the external fold and the internal fold, and
(ii) an internal extension fabric portion that is made from a second, non-mesh flame retardant textile material that is different from the first material, and that extends from the mesh portion to the internal fold;
(e) wherein the proximal fabric layer is interconnected with and made from the same flame retardant textile material as the internal extension fabric portion, the internal fold comprising a defined fold in the flame retardant textile material of the proximal fabric layer and the internal extension fabric portion;
(f) wherein, when the vent is in a closed position, the central venting layer is sandwiched between the flame retardant proximal fabric layer and the flame retardant distal fabric layer;
and
(g) wherein, when a flame blast is directed toward the vent, the proximal fabric layer and the distal fabric layer are configured to move toward and sandwich the central venting layer to close the vent for preventing the flame blast from entering the flame retardant protective garment through the vent.

The flame retardant protective garment having sleeves, and further comprising vents that allow ventilation of the garment,

(a) wherein each said vent comprises:
(i) a flame retardant proximal fabric layer;
(ii) a central venting layer connected to the proximal fabric layer by an internal fold;
and
(iii) a flame retardant distal fabric layer connected to the central venting layer by an external fold;
(iv) wherein the central venting layer comprises:
(A) a mesh portion that is made from a first flame retardant material, that is configured to allow a flow of air to pass therethrough, and that is located between the external fold and the internal fold, and
(B) an internal extension fabric portion that extends between the mesh portion and the internal fold and that comprises a second, non-mesh flame retardant textile material;
(v) wherein the proximal fabric layer is interconnected with and made from the same material as the internal extension fabric portion, the internal fold comprising a defined fold in the flame retardant textile material of the proximal fabric layer and the internal extension fabric portion;
(vi) wherein, when the vent is in a closed position, the central venting layer is sandwiched between the flame retardant proximal fabric layer and the flame retardant distal fabric layer;
and
(vii) wherein, when a flame blast is directed toward the vent, the proximal fabric layer and the distal fabric layer are configured to move toward and sandwich the central venting layer to close the vent for preventing the flame blast from entering the flame retardant protective garment through the vent;
and
(b) wherein a first vent of said vents extends along a right-rear side of the garment, and a second vent of said vents extends along a left-rear side of the garment.

A flame retardant protective coverall having a lower portion with legs and a top portion with sleeves, and further comprising vents that allow ventilation of the coverall,

(a) wherein each said vent comprises:
(i) a flame retardant proximal fabric layer;
(ii) a central venting layer connected to the proximal fabric layer by an internal fold;
and
(iii) a flame retardant distal fabric layer connected to the central venting layer by an external fold;
(iv) wherein the central venting layer comprises:
(A) a mesh portion that is made from a first flame retardant material, that is configured to allow a flow of air to pass therethrough, and that is located between the external fold and the internal fold, and
(B) an internal extension fabric portion that extends between the mesh portion and the internal fold and that comprises a second, non-mesh flame retardant textile material;
(v) wherein the proximal fabric layer is interconnected with and made from the same material as the internal extension fabric portion, the internal fold comprising a defined fold in the flame retardant textile material of the proximal fabric layer and the internal extension fabric portion;
(vi) wherein, when the vent is in a closed position, the central venting layer is sandwiched between the flame retardant proximal fabric layer and the flame retardant distal fabric layer;
and
(vii) wherein, when a flame blast is directed toward the vent, the proximal fabric layer and the distal fabric layer are configured to move toward and sandwich the central venting layer to close the vent for preventing the flame blast from entering the flame retardant protective coverall through the vent;
and
(b) wherein a first vent of said vents extends along a right-rear side of the top portion of the coverall, a second vent of said vents extends along a left-rear side of the top portion of the coverall, a third vent of said vents extends across a rear mid-portion of a right leg of the lower portion of the coverall, and a fourth vent of said vents extends across a rear mid-portion of a left leg of the lower portion of the coverall.
