In the'N'etl erlands- I lecember 6, 19d? 3 Claims. 1.

The invention has for: its purpose the manufacture of waterproof garments in which the ventilation openings are arranged insuch a Way, that there is no need of any particular'measure for preventing the rain from penetrating into the same, that the said openings always remain wellopened, and that the 'said' waterproof garment, considered from an aesthetical' point of view, will satisfy the strictest requirements.

The novel rain proof garments according to the present invention are characterized: by the fact that the ventilation openings are situated in those folds of a box pleat that, viewed from the outside of the garment, are covered by the material of the pleat.

The openings preferably are made in the shape of vertical and/or transverse slits. It, is also possible to use V-shaped slits whichas it has been fOllIld-Will always provide ventilation, even if the box pleat should be flattened'down.

In order to make it possible if desired, to re.- duce too strong a ventilation, it is to be recommended that. the openings are madeiin the shape of two rows of eyelets situated on either side of the above mentioned fold.

It will then be possible to close the openings entirely or partly by means of the lace.

As it is important that the ventilation openings remain also free at the side turned towards the body, it is advisable to provide a distancing cushion back of the box pleat, which will greatly increase the possibilities of ventilation.

It may, however, be desired to cover up the ventilation openings.

Besides the above mentioned lace, one may also use for the above purpose a distancing cushion consisting of folded strips of a suitable material. By unfolding the said strips one may cover up the ventilation openings and obtain at the same time a. lining that will serve as a protection against the cold.

In order to keep the said lining in the desired position, it is desirable that the dimensions of the strips are such that the said strips when unfolded and laid out flat may be connected with each other by means of snap fasteners or the like.

The ventilation openings will produce a maximum effect, if there is provided on the inner side of the garment a piece of lining consisting of an absorbent porous textile material of the cotton type, woven as a canvas texture of loosely twined threads with openings like those of a grating.

If still more possibilities for ventilation, e. g.

shoulders, should be desired, the waterproof garments according to the invention may be provided with one or more backor arm pieces, applied on top' of the lining-and detachably attached thereto, at least at th bottom.

The said lining provides a breathing layer between the bodyof the wearer and the waterproof garment, which layer will readily absorb perspiration and discharge the same outwards through the ventilation openings.

The waterproof garment therefore will protect the wearer againstthe penetration of rain, while the lining will protect him against the consequences of perspiration. The ventilation openings provided in the garment make it possible for the lining to carry out its specific function completely. I

By means of the back piece and the arm pieces the large quantity of-"perspiration' that may be formed on the back or on the shoulders of the wearer can be absorbed by the lining and discharged out-ward without any difliculty. A garment made according to the invention, moreover, presents a very pleasingappearance from an aesthetic point of view.

The invention will now be further explained with the aid of the accompanying drawings, of which:

Fig. 1 represents a view of a portion of the back of a rain coat according to the invention,

Fig. 2 is a section along the line II-II in Fig. 1,

Fig. 3 is a section along the line III-III in Fig.1,

Fig. 4 is a section similar to Fig. 3, in which the distancing cushions have been unfolded and laid out flat, while Figs. 5-8 represent a plurality of embodiments of the ventilation openings, in which the box pleats are represented unfolded and laid out flat.

In the said drawings the reference numeral I represents the rain coat, which is provided with a shoulder-piece 2 attached by means of snap fasteners 3.

Underneath the said shoulder-piece there is provided a piece of gauze fabric 6 serving as a ventilation means.

The upper parts of the sleeves are covered by arm pieces 5 which are also detachably fastened by means of snap fasteners 3. Underneath the arm pieces there is provided ventilation gau e 5.

In the back there are provided box pleats behind which the distancing cushions 8 are atfor the upper portion of the back or for the tached. These cushions consist of strips of folded flannel that are kept in this condition by means of snap fasteners 9.

If the strips 8 are unfolded (cf. Fig. 4) the snap fasteners 9 will connect one strip with the other, thus forming a piece of lining.

The box pleats are provided on the folds ID with ventilation openings, into which the rain is thus prevented from penetrating.

The ventilation openings may be V-shaped (l l and 12 in Fig. 5) or they may have the form of transversal slits I3 in Fig. 5)

They may also consist in vertical slits (l4 and l5inFig.6or I6inFig.7).

The openings may also consist in a combination of Vertical and transversal slits (I1 and I8 inFig.7or2l inFig.8).

In order to make it possible to limit the width of the ventilation slits, use is made of eyelets [9 for a closing lace 20.

The said eyelets l9 themselves may also serve as ventilation openings (Fig. 8, right hand side).

With the novel waterproof garments according to the invention, the ventilation openings are not only completely protected against the penetration of rain, but they also are permanently kept well-opened, since they are situated on a fold and therefore will remain open on account of the bending of the said fold, even if the box pleats were flattened down.

It is likewise impossible to close the ventilation openings by exerting pressure on the same, because of the distancing cushions 8 which entirely clear the edges [0, since the pressure of the body is transmitted to the box pleats, but only in those places Where the edges l0 are not present.

The lining which may be woven as a plaiting comprising thick knots, also may act as a distancing means between the body and the box pleats.

Because of the shape of the ventilation openings and the manner in which they are situated, the said openings will automatically expand energetically, especially if a horizontal opening s succeeded by a vertical one, since in that case a particularly good counter-pressure will be produced.

Finally a strip of a rubberized material may be pasted on to the backs of the box pleats, whereby the elasticity of the said pleats will be increased and consequently the closing of the openings will be prevented.

I claim:

1. A ventilated waterproof garment, such as a rain coat, comprising a body covering portion including a back, said back portion being formed of waterproof material and being folded along vertically extending lines to provide a plurality of box pleats, each of said pleats having inner folds and outer folds, said material being apertured along at least one of said inner folds to provide ventilation openings which are covered by the material of said pleats when the garment is viewed from the outside, and a spacing strip behind each of said box pleats to hold the apertured inner fold lines away from the wearers body, said spacing strip consisting of a folded strip of flexible material.

2. A waterproof garment according to claim 1, in which the width of the strips when unfolded is at least equal to the distance between successive pleats so that the unfolded strips form a continuous lining.

3. A waterproof garment according to claim 2, in which fastening means is provided for connecting adjacent strips to one another when unfolded.
