Abstract
ABSTRACT OF THE DISCLOSURE
A coverall-type protective/working garment sealing against the wearer's neck, arms and legs, comprises two separate layers, of which the inner layer next to the body is breathable and capable of letting through moisture/vapors (sweat) from its inner side to its outer side, and the outer layer is substantially airtight, except in at least one lower region located above the leg seal, and at least one upper region located below the neck seal, in which regions the outer layer is air-permeable, such that surrounding air admitted through said air-permeable lower region to the space between said layers will carry along, by chimney effect, any moisture/vapors admitted by said inner layer to said space, out through the air-permeable upper region of said outer layer.

Description
The present invention relates to a protective/
working garment intended primarily for work in the vicinity of water, such as off-shore work in cold weather.
Known garments for these purposes, when combined with an insulating material, suffer from the disadvantage that they are poorly ventilated, which means that the user's transpiration is not effectively led away from the body and the garment, but remains on the body and is absorbed by the material of the garment, thereby causing the wearer to feel uncomfortable.
It is the object of this invention to provide a garment which does not suffer from this disadvantage, i.e.
a garment which is ventilated and, at the same time, is thermally insulated as well as water and air tight.
To achieve this object, the garment according to the invention has been given the characteristic features defined by the appended claims.
The invention will be described in greater detail below, reference being made to the accompanying drawing illustrating an embodiment of the garment in a transparent view.
The coverall-type protective garment illustrated comprises an outer layer 1 and an inner layer 2 next to the body and spaced from said outer layer. The outer layer 1 covers the entire body, except the face, and the inner layer
working garment intended primarily for work in the vicinity of water, such as off-shore work in cold weather.

It is the object of this invention to provide a garment which does not suffer from this disadvantage, i.e.
a garment which is ventilated and, at the same time, is thermally insulated as well as water and air tight.
To achieve this object, the garment according to the invention has been given the characteristic features defined by the appended claims.
The invention will be described in greater detail below, reference being made to the accompanying drawing illustrating an embodiment of the garment in a transparent view.
The coverall-type protective garment illustrated comprises an outer layer 1 and an inner layer 2 next to the body and spaced from said outer layer. The outer layer 1 covers the entire body, except the face, and the inner layer
2 covers the entire body, except the feet, the hands and the face. The outer layer 1 thus has a body portion lay a hood portion lb, shoe portions to and glove portions id, and the inner layer 2 has a body portion pa and a hood portion 2b.
The body portion lo of the outer layer 1 consists of watertight material, except in a preferably circumfer-entail region to directly above the respective shoe portion to and a relatively larger shoulder portion if where the outer layer 1 consists of a watertight, hydrophobic and breathable material. The connection between these regions .,~, isle ye, if and the remainder of the outer layer 1 is watertight.
Also the hood portion lb, the shoe portions to and the glove portions id are at least watertight, as is the connection of these portions with the body portion lay The inner layer 2 consists of a thermally insulated, breathable material letting through moisture/vapors, without any appreciable capacity to absorb moisture/vapors. At its ankle and wrist portions, the inner layer 2 has sealing means
The body portion lo of the outer layer 1 consists of watertight material, except in a preferably circumfer-entail region to directly above the respective shoe portion to and a relatively larger shoulder portion if where the outer layer 1 consists of a watertight, hydrophobic and breathable material. The connection between these regions .,~, isle ye, if and the remainder of the outer layer 1 is watertight.
Also the hood portion lb, the shoe portions to and the glove portions id are at least watertight, as is the connection of these portions with the body portion lay The inner layer 2 consists of a thermally insulated, breathable material letting through moisture/vapors, without any appreciable capacity to absorb moisture/vapors. At its ankle and wrist portions, the inner layer 2 has sealing means
3 for a substantially sealing adhesion at the ankle and wrist areas to the inner sides of the shoe portions to and the glove portions id. The adhesion is established, for example, by means of a Velcro (a trademark) tape.
Water and air tight zip fasteners or other opening/
closing means (not shown) in/at the outer layer 1 give access to these fastening arrangements and permit, together with zip fasteners or other opening/closing means in/at the inner layer 2, the wearer to climb into the garment.
By this arrangement, it is achieved that air admitted through the region to into the space between the outer layer 1 and the inner layer 2 is caused to flow upwardly under the action of the chimney effect promoted by the body heat and to carry along the moisture/vapors permeating through the inner layer 2 from the inner side to the outer side thereof, out through the shoulder region if. This function of the garment is shown by arrows A (air), S (sweat) and AS.
The garment can be supplemented with a face protection sealing between the outer and inner layers 1, 2 pockets, padding in, for example, the region of the knees, life-jacket etc., to suit the contemplated use of the garment. Regions similar to the regions to and if may be provided in the outer layer 1 in other parts thereof, for instance in the glove portions and the crotch portions.
Suitable materials for the outer layer 1 and the inner layer 2 are already available on the market. In one .' ~:1~7 ', Tao embodiment of the invention, the body portion lo of the outer layer 1 consists, except for the regions to and if, of heat-weldable fiberglass fabric coated with polyurethane or silicone affording the desired water and air tightness in this portion.
The active component of the regions to and if is a layer of micro porous hydrophobic, breathable and, at least in the inward-outward direction, vaporpervious semi-permeable membrane. One example of such membranes is GORE-TEX ( a trademark of WYLIE. Gore & Co.), consisting of or containing expanded polytetrafluoroethylene. The membrane can be externally laminated, with some knitted or woven flame-resistant fabric, such as Nomex (a trademark of Dupont) and, internally, with a self-extinguishing flame-protecting fabric such as SEX
(a trademark of Monsanto). This laminate is a suitable material for the regions to, if of the outer layer 1 and is being used already in the manufacture of survival clothing, tent-canvas, sleeping-bags eta, and can be sewn together with the above-mentioned fiberglass material, whereupon the seams are sealed by means of some suitable, tight and sealing adhesive strip.
In this embodiment, the active component of the inner layer 2 consists of Thinsulate (a trademark of Minnesota Mining and Manufacturing Company), which comprises 65% olefin fibers and 35~ polyether fibers. This material is light, washable and allergy-tested and, furthermore, has the characteristics desired for the present invention, i.e.
breathability, low moisture/vapor adsorbability, but high moisture/vapor permeability and insulation capacity. Laminated with non-woven paper pulp on the outer side, it effectively prevents the return of moisture/vapors back to the body side.
The laminate is available on the market with a nylon layer on the inner and outer sides and is being used already for the manufacture of, for example, outdoor garments.
