Definitions
- the present invention relates to improvements made to a sleeping bag, in particular for campers, mountaineers, hikers, etc. and of the reversible type.
- sleeping bags of this type consist of a quadrangular panel made of flexible material and provided with an insulating lining and folded back on itself, two sides at right angles to one face being joined by a zipper at the two opposite sides from the other side.
- Sleeping bags of this type are already known in which the two upper and lower sides of the bag respectively are provided with different properties both with regard to, for example, the thermal insulation coefficients, the nature of the lining material and the possibilities comfort and cushioning they represent.
- Such sleeping bags have the particular advantage of allowing, depending on the circumstances, tastes or the choice of the user, to put one or the other face in a higher or lower position, so as to take maximum advantage properties offered by each face.
- two faces can be provided with different insulation qualities, so that the user can, depending on the season, put in the upper position (that is to say in the active body protection position), the most insulating side or the least insulating side; and thus the same bag can be used in any season, the appropriate face being placed in the upper position according to the ambient temperature at the time of use.
- hood controls the use of the bag, the side devoid of hood or cap necessarily being placed in the upper position or in the cover and body protection.
- a sleeping bag as described in the preamble of claim 1 is known from US-A-4,183,111.
- the present invention aims to remedy these drawbacks and makes it possible to produce a sleeping bag of the reversible type, that is to say with two sides having notably insulating or different comfort properties, while allowing the implementation of a hood associated with each of the faces.
- the invention relates to a sleeping bag as characterized in claim 1.
- each cap comprises, in a manner known per se, a flexible peripheral sheath provided with an inner lace allowing the edges of the cap to be tightened by closing it around the head of the user and, at the level of the upper opening of the bag, a flexible sheath transversely traversing said face in the zone corresponding to the separation between the top of this face and the cap which corresponds to it and which extends this face, said flexible sheath being provided with a lace allowing the opening of the bag to be tightened around the neck of the user once in place in the bag, and provision has been made for the same lace, traversing the flexible sheath provided on a cap, to extend into the flexible sheath arranged transversely on the top of the opposite face, so that this same lace allows both to tighten the cap around the head of the user and at the same time tighten the upper opening of the bag around the neck of the user by the contraction of the side of the bag opposite the cap placed in the active position.
- each lace successively traversing a flexible sheath at the top of one face of the bag and extending into the peripheral flexible sheath around the opposite cap has a free end to allow the cumulative tightening of the edges of the cap brought into the active position and from the top of the opposite face of the sa put in the upper position, the opposite end of this lace being blocked, for example by sewing, at the end of its receiving sheath.
- the blocked end of this lace extends outside of its receiving sheath to conform a fixed loop capable of receiving in the engagement position the free end of this lace.
- each face of the bag comprises means for immobilizing the hood or cap which extend said face, brought into a compacted position for placing it in the inactive position.
- Figure 1 shows a perspective view of the entire bag in the spread position.
- FIG. 2 represents a detail view showing the ends of the links intended to allow the shaping of the bag for its use.
- FIG. 3 represents a perspective view of the bag after picking up and compacting the cap corresponding to the upper face thus brought into the inactive position.
- FIG. 4 represents the final phase of the bag placed in the position of use, the cap extending the underside of the bag being tightened around the head of the user, at the same time as the edge of the face of the bag brought into position. upper is also tightened around the user's neck.
- the sleeping bag has two faces 1 and 2 respectively, each face being itself extended by a cap 3 and 4 in the form of a semi-circular yoke extending the corresponding face.
- each of the caps 3,4 comprise a flexible sheath 5,6 provided internally with a link such as a lace 7,8 and making it possible to tighten the cap around the head of the user.
- each upper part of a face 1, 2 of the bag comprises, substantially at the level of the zone corresponding to the top of the bag and the separation limit between a face and the cap which extends this face, a flexible sheath respectively 9.10; this sheath internally containing a link such as a lace allowing retraction and compaction of the top of the bag around the user's neck.
- the link such as a lace 7 runs through the sheath 6 which follows the edge of the lower cap 4.
- This link therefore penetrates through the opening 6a of the sheath 6 and it emerges at the opposite edges 6b; from there it engages in the end 9a of the sheath 9 to end at the end 9b of this sheath.
- This link 7 could come out freely from this end 9b to allow by knotting to operate both the tightening of the edge of the lower cap 4 and the tightening of the upper face 1 of the bag around the user's neck.
- each link has a free end respectively 7 and 8; and the opposite end respectively 7a and 8a is locked, for example by sewing in the end of the receiving sheath 9b and 10b respectively.
- each end conforms to a loop 7a, 8a which can receive the free end of the opposite link.
- the bag comprises, on each face 1 and 2 respectively, and on each of the respectively external and internal walls of each of its faces, a plurality of free links 11, 12, 13 and 11 ′, 12 ', 13', these links being arranged on each wall substantially opposite one with respect to the other and being aligned in the upper part of each face, in the zone corresponding to the separation between the face and the cap which extends this face.
- each face 1 and 2 respectively of the bag can be provided according to characteristics in particular of comfort or of insulating power different from each other; this therefore allows the user to choose as a function of time, temperature, circumstances, etc. that of the two faces which will have to be placed in the lower position, to serve as a resting surface and the face which will be put in the upper position to serve as cover and protection.
- the links 11, 11 ′ which are arranged respectively on an external wall and an internal wall of the upper face 1 are joined together by enclosing between them a part of the cap 3; it is the same for the other links 12, 12 ′ and 13, 13 ′ which are coupled, for example by knotting and which thus return to the compacted position and pick up the cap 3 thus brought into the inactive position.
- the user can then enter the bag, in a conventional manner by folding down the two faces 1 and 2 which will then be assembled by the zipper 14.
- the user can then bring the lower cap 4 in the protective position around his head by the play of the lace 7 which allows to tighten, according to the sheath 6, that is to say along the edges of the lower cap 4, the whole of the cap thus brought back around the head of the user; and the traction exerted on the lace 7 allows at the same time, since the lace 7 is extends in the transverse sheath 9 which runs through the upper part of the face 1 of the bag (opposite the cap 4) to tighten at the same time the upper part of the face 1 at the level of the user's neck.
- the lace 7 is engaged by its free end 7a in the loop 7b and it is possible to immobilize this free end 7a at the level of tightening desired by the play of a blocking glans of known type 15.
- the invention therefore makes it possible to advantageously produce a sleeping bag allowing the advantages and properties of the reversible sleeping bag to be used in a new way, each side having differential properties capable of being used depending on the circumstances, and at the same time the interest and comfort of a susceptible cap to be put into service, from the underside; while the opposite cap can be deactivated and compacted, thereby avoiding interfering with or disturbing the sleeper's breathing.
- the deactivated and folded hood on the chest provides additional thermal protection.
Description
La présente invention concerne des perfectionnements apportés à un sac de couchage notamment pour campeurs, alpinistes, randonneurs, etc... et du type réversible.The present invention relates to improvements made to a sleeping bag, in particular for campers, mountaineers, hikers, etc. and of the reversible type.
On connaît des sacs de couchage conformés d'une façon générale sous forme d'une poche à deux faces laissant une ouverture supérieure pour la tête de l'utilisateur.There are known sleeping bags generally shaped as a two-sided pocket leaving an upper opening for the head of the user.
Plus spécialement les sacs de couchage de ce type sont constitués d'un panneau quadrangulaire en matériau souple et pourvu d'un garnissage isolant et replié sur lui-même, deux côtés à angle droit d'une face étant réunis par une fermeture à glissière aux deux côtés en regard venus de l'autre face.More specifically, sleeping bags of this type consist of a quadrangular panel made of flexible material and provided with an insulating lining and folded back on itself, two sides at right angles to one face being joined by a zipper at the two opposite sides from the other side.
On connaît déjà des sacs de couchage de ce type dans lequel les deux faces respectivement supérieure et inférieure du sac sont prévues avec des propriétés différentes tant en ce qui concerne par exemple les coefficients d'isolation thermique que la nature du matériau de garnissage et les possibilités de confort et d'amortissement qu'ils représentent.Sleeping bags of this type are already known in which the two upper and lower sides of the bag respectively are provided with different properties both with regard to, for example, the thermal insulation coefficients, the nature of the lining material and the possibilities comfort and cushioning they represent.
De tels sacs de couchage présentent notamment l'avantage de permettre, selon les circonstances, les goûts ou le choix de l'utilisateur, de mettre l'une ou l'autre face en position supérieure ou inférieure, de façon à tirer profit au maximum des propriétés offertes par chaque face.Such sleeping bags have the particular advantage of allowing, depending on the circumstances, tastes or the choice of the user, to put one or the other face in a higher or lower position, so as to take maximum advantage properties offered by each face.
A titre d'exemple on peut prévoir dans ce type connu de sac de couchage deux faces comportant des qualités d'isolation différentes, de sorte que l'utilisateur pourra, suivant la saison, mettre en position supérieure (c'est-à-dire en position active de protection corporelle), la face la plus isolante ou au contraire la moins isolante ; et ainsi un même sac pourra être utilisé en toute saison, la face appropriée étant mise en position supérieure selon la température ambiante au moment de l'utilisation.For example, in this known type of sleeping bag two faces can be provided with different insulation qualities, so that the user can, depending on the season, put in the upper position (that is to say in the active body protection position), the most insulating side or the least insulating side; and thus the same bag can be used in any season, the appropriate face being placed in the upper position according to the ambient temperature at the time of use.
Toutefois il suit que ces sacs de couchage du type réversible, peuvent difficilement être prévus avec une capuche ou capuchon destinés à entourer la tête de l'utilisateur.However, it follows that these reversible sleeping bags can hardly be provided with a hood or hood intended to surround the head of the user.
En effet dans ce cas si une seule capuche est prévue sur une face, il suit que la position de la capuche commande l'utilisation du sac, la face dépourvue de capuche ou capuchon étant nécessairement mise en position supérieure ou en position de couverture et de protection du corps.In this case, if only one hood is provided on one side, it follows that the position of the hood controls the use of the bag, the side devoid of hood or cap necessarily being placed in the upper position or in the cover and body protection.
Si l'on dispose deux capuches ou capuchons, c'est-à-dire un capuchon sur chaque face, il apparaît alors que le capuchon qui sera inactif viendra gêner la face de l'utilisateur et la recouvrir avec éventuellement des risques d'étouffement ou en tout cas de gêne dans la respiration.If there are two hoods or caps, that is to say a cap on each side, it then appears that the cap which will be inactive will interfere with the face of the user and cover it with possibly risks of suffocation or in any case of discomfort in breathing.
Il existe également des sacs de couchage comportant trois couches dont deux couch'es extérieures à caractéristiques d'isolation identiques entre lesquelles est insérée une couche intermédiaire ; cette structure permet deux positions d'utilisation suivant que le dormeur disposera au-dessus de son corps une seule couche extérieure ou à la fois une couche extérieure et la couche intermédiaire. Cette configura:ion ne permet cependant d'ouvrir le sac par la fermeture à glissière que pour une seule position d'utilisation du sac.There are also sleeping bags comprising three layers including two outer layers with identical insulation characteristics between which an intermediate layer is inserted; this structure allows two positions of use depending on whether the sleeper will have above his body a single outer layer or both an outer layer and the intermediate layer. This configuration, however, only allows the bag to be opened by the zipper for one position of use of the bag.
On connaît par le brevet US-A- 4,183,111 un sac de couchage tel que décrit dans le préambule de la revendication 1.A sleeping bag as described in the preamble of claim 1 is known from US-A-4,183,111.
La présente invention vise à remédier à ces inconvénients et permet de réaliser un sac de couchage du type réversible c'est-à-dire avec deux faces comportant des propriétés notamment isolantes ou de confort différentes, tout en permettant la mise en oeuvre d'un capuchon associé à chacune des faces.The present invention aims to remedy these drawbacks and makes it possible to produce a sleeping bag of the reversible type, that is to say with two sides having notably insulating or different comfort properties, while allowing the implementation of a hood associated with each of the faces.
A cet effet, l'invention concerne un sac de couchage telle qu'elle est caractérisée dans le revendication 1.To this end, the invention relates to a sleeping bag as characterized in claim 1.
Plus spécialement chaque capuchon comporte de façon connue en soi une gaine périphérique souple garnie d'un lacet intérieur permettant de resserrer les bords du capuchon en le refermant autour de la tête de l'utilisateur et, au niveau de l'ouverture supérieure du sac une gaine souple parcourant transversalement ladite face dans la zone correspondant à la séparation entre le sommet de cette face et le capuchon qui lui correspond et qui prolonge cette face, ladite gaine souple étant garnie d'un lacet permettant de resserrer l'ouverture du sac autour du cou de l'utilisateur une fois en place dans le sac, et on a prévu que le même lacet, parcourant la gaine souple prévue sur un capuchon se prolonge dans la gaine souple disposée transversalement sur le sommet de la face opposée, de sorte que ce même lacet permet à la fois de resserrer le capuchon autour de la tête de l'utilisateur et de resserrer en même temps l'ouverture supérieure du sac autour du cou de l'utilisateur par la contraction de la face du sac opposée au capuchon mis en position active.More specifically, each cap comprises, in a manner known per se, a flexible peripheral sheath provided with an inner lace allowing the edges of the cap to be tightened by closing it around the head of the user and, at the level of the upper opening of the bag, a flexible sheath transversely traversing said face in the zone corresponding to the separation between the top of this face and the cap which corresponds to it and which extends this face, said flexible sheath being provided with a lace allowing the opening of the bag to be tightened around the neck of the user once in place in the bag, and provision has been made for the same lace, traversing the flexible sheath provided on a cap, to extend into the flexible sheath arranged transversely on the top of the opposite face, so that this same lace allows both to tighten the cap around the head of the user and at the same time tighten the upper opening of the bag around the neck of the user by the contraction of the side of the bag opposite the cap placed in the active position.
Selon encore une autre caractéristique chaque lacet, parcourant successivement une gaine souple au sommet d'une face du sac et se prolongeant dans la gaine souple périphérique autour du capuchon opposé comporte une extrémité libre pour permettre le resserrement cumulatif des bords du capuchon amenés en position active et du sommet de la face opposée du sa mis en position supérieure, l'extrémité opposée de ce lacet étant bloquée, par exemple par couture, à l'extrémité de sa gaine réceptrice.According to yet another characteristic, each lace, successively traversing a flexible sheath at the top of one face of the bag and extending into the peripheral flexible sheath around the opposite cap has a free end to allow the cumulative tightening of the edges of the cap brought into the active position and from the top of the opposite face of the sa put in the upper position, the opposite end of this lace being blocked, for example by sewing, at the end of its receiving sheath.
Selon une autre caractéristique l'extrémité bloquée de ce lacet se prolonge à l'extérieur de sa gaine réceptrice pour conformer une boucle fixe apte à recevoir en position d'engagement l'extrémité libre de ce lacet.According to another characteristic, the blocked end of this lace extends outside of its receiving sheath to conform a fixed loop capable of receiving in the engagement position the free end of this lace.
De préférence encore chaque face du sac comporte des moyens d'immobilisation de la capuche ou capuchon qui prolongent ladite face, amenés dans une position compactée pour sa mise en position inactive.More preferably, each face of the bag comprises means for immobilizing the hood or cap which extend said face, brought into a compacted position for placing it in the inactive position.
D'autres caractéristiques et avantages de l'invention ressortiront de la description qui suit et qui est donnée en rapport avec une forme de réalisation particulière présentée à titre d'exemple non limitatif et en se référant aux dessins annexés.Other characteristics and advantages of the invention will emerge from the description which follows and which is given in relation to a particular embodiment presented by way of nonlimiting example and with reference to the appended drawings.
La figure 1 représente une vue en perspective de l'ensemble du sac en position étalée.Figure 1 shows a perspective view of the entire bag in the spread position.
La figure 2 représente une vue de détail montrant les extrémités des liens destinés à permettre la mise en forme du sac pour son utilisation.FIG. 2 represents a detail view showing the ends of the links intended to allow the shaping of the bag for its use.
La figure 3 représente une vue en perspective du sac après ramassage et compactage du capuchon correspondant à la face supérieure ainsi amenée en position inactive.FIG. 3 represents a perspective view of the bag after picking up and compacting the cap corresponding to the upper face thus brought into the inactive position.
Et la figure 4 représente la phase finale du sac mis en position d'utilisation, le capuchon prolongeant la face inférieure de sac étant resserré autour de la tête de l'utilisateur, en même temps que le bord de la face du sac amené en position supérieure est également resserré autour du cou de l'utilisateur.And FIG. 4 represents the final phase of the bag placed in the position of use, the cap extending the underside of the bag being tightened around the head of the user, at the same time as the edge of the face of the bag brought into position. upper is also tightened around the user's neck.
Selon l'ensemble des figures on voit que le sac de couchage comporte deux faces respectivement 1 et 2, chaque face étant prolongée elle-même par un capuchon 3 et 4 sous forme d'un empiècement semi-circulaire prolongeant la face correspondante.According to all of the figures, it can be seen that the sleeping bag has two
De façon connue, les bords périphériques de chacun des capuchons 3,4 comportent une gaine souple 5,6 pourvue intérieurement d'un lien tel qu'un lacet 7,8 et permettant de resserrer le capuchon autour de la tête de l'utilisateur.In known manner, the peripheral edges of each of the
En outre et selon l'invention chaque partie supérieure d'une face 1,2 du sac comporte, sensiblement au niveau de la zone correspondant au sommet du sac et à la limite de séparation entre une face et le capuchon qui prolonge cette face, une gaine souple respectivement 9,10 ; cette gaine contenant intérieurement un lien tel qu'un lacet permettant la rétraction et le compactage du sommet du sac autour du cou de l'utilisateur.In addition and according to the invention, each upper part of a
Et avantageusement on a prévu que le même lien respectivement 7,8, parcourant une gaine souple périphérique à chaque capuchon, se prolonge dans la gaine respectivement 9,10, qui parcourt la partie supérieure de la face du sac, opposée au capuchon.And advantageously, provision has been made for the same link respectively 7.8, passing through a flexible sheath peripheral to each cap, to be extended in the sheath respectively 9.10, which runs through the upper part of the face of the bag, opposite the cap.
Ainsi et comme on le voit par exemple sur la figure 2, le lien tel qu'un lacet 7, parcourt la gaine 6 qui suit le bord du capuchon inférieur 4.Thus, as can be seen for example in FIG. 2, the link such as a
Ce lien pénètre par conséquent par l'ouverture 6a de la gaine 6 et il ressort aux bords opposés 6b ; de là il s'engage dans l'extrémité 9a de la gaine 9 pour aboutir à l'extrémité 9b de cette gaine.This link therefore penetrates through the opening 6a of the
Ce lien 7 pourrait sortir librement de cette extrémité 9b pour permettre par nouage d'opérer à la fois le resserrement du bord du capuchon inférieur 4 et le resserrement de la face supérieure 1 du sac autour du cou de l'utilisateur.This
La mise en position inactive du capuchon supérieur 3 sera ultérieurement décrite et illustrée aux figures 3 et 4.The placing of the
Pareillement on voit que le lien 8 pénètre dans la gaine 5 correspondant au capuchon supérieur 3 par l'extrémité ouverte 5a de cette gaine.Similarly we see that the
Et il va ensuite sortir en 5b pour pénétrer dans l'extrémité 10a de la gaine parcourant la face inférieure opposée du sac.And it will then exit at 5b to enter the end 10a of the sheath traversing the opposite underside of the bag.
Et ce même lien 8 va donc déboucher à l'extérieur de la gaine 10 par son extrémité 10b.And this
Selon l'exemple qui est ici décrit et illustré, chaque lien comporte une extrémité libre respectivement 7 et 8 ; et l'extrémité opposée respectivement 7a et 8a est bloquée, par exemple par couture dans l'extrémité de la gaine réceptrice respectivement 9b et 10b.According to the example which is here described and illustrated, each link has a free end respectively 7 and 8; and the opposite end respectively 7a and 8a is locked, for example by sewing in the end of the receiving sheath 9b and 10b respectively.
Ainsi chaque extrémité conforme une boucle 7a,8a qui peut recevoir l'extrémité libre du lien opposé.Thus each end conforms to a
On voit ainsi que l'extrémité libre 7a du lien 7, débouchant depuis l'ouverture 6a de la gaine 6, affectant le capuchon inférieur, est passée dans la boucle 7b qui sort elle-même de l'extrémité 9b de la gaine 9 affectant la face supérieure 1 du sac.It is thus seen that the
Selon une autre caractéristique de l'invention le sac comporte, sur chaque face respectivement 1 et 2, et sur chacune des parois respectivement externe et interne de chacune de ses faces, une pluralité de liens libres 11,12,13 et 11',12',13', ces liens étant disposés sur chaque paroi sensiblement en regard l'un par rapport à l'autre et étant alignés dans la partie supérieure de chaque face, dans la zone correspondant à la séparation entre la face et le capuchon qui prolonge cette face.According to another characteristic of the invention, the bag comprises, on each
Et le fonctionnement du sac ainsi décrit est le suivant : On rapellera que selon une caractéristique connue, chaque face respectivement 1 et 2 du sac peut être prévue selon des caractéristiques notamment de confort ou de pouvoir isolant différentes l'une de l'autre ; ceci permet par conséquent à l'utilisateur de choisir en fonction du temps, de la température, des circonstances, etc... celle des deux faces qui devra être mise en position inférieure, pour servir de surface de repos et la face qui sera mise en position supérieure pour servir de couverture et de protection.And the functioning of the bag thus described is as follows: It will be recalled that according to a known characteristic, each
Ainsi le sac ayant été positionné selon le choix de l'utilisateur, il apparaît selon la figure 1 que le capuchon 3 qui se trouve en position supérieure doit être dégagé et désactivé de façon à ne pas gêner la respiration du dormeur.Thus the bag having been positioned according to the choice of the user, it appears from Figure 1 that the
A cet effet on utilise les liens 11,12,13,11',12',13' selon la vue de la figure 3.For this purpose, the
Les liens 11,11' qui sont disposés respectivement sur une paroi externe et une paroi interne de la face supérieure 1 sont réunis en enfermant entre eux une partie du capuchon 3; il en est de même des autres liens 12,12' et 13,13' qui sont accouplés, par exemple par nouage et qui ramènent ainsi en position compactée et ramassée le capuchon 3 ainsi amené en position inactive.The
Ultérieurement l'utilisateur peut dont s'introduire dans le sac, de façon classique en rabattant les deux faces 1 et 2 qui seront ensuite assemblées par la fermeture à glissière 14.Subsequently, the user can then enter the bag, in a conventional manner by folding down the two
Une fois en place dans le sac de couchage l'utilisateur peut alors amener le capuchon inférieur 4 en position de protection autour de sa tête par le jeu du lacet 7 qui permet de resserrer, selon la gaine 6, c'est-à-dire selon les bords du capuchon inférieur 4, l'ensemble du capuchon ainsi ramené autour de la tête de l'utilisateur ; et la traction exercée sur le lacet 7 permet en même temps, puisque le lacet 7 se prolonge dans la gaine transversale 9 qui parcourt la partie supérieure de la face 1 du sac (opposée au capuchon 4) de resserrer en même temps la partie supérieure de la face 1 au niveau du cou de l'utilisateur.Once in place in the sleeping bag the user can then bring the
Dans ces conditions on voit que par un même mouvement et en utilisant le même lacet 7, l'utilisateur va pouvoir resserrer autour de sa tête la capuchon et le bord supérieur du sac en assurant ainsi une protection hermétique du corps, ne laissant dégager que la partie avant de la face de l'utilisateur pour les besoins de sa respiration et de son confort.Under these conditions we see that by the same movement and using the
Le lacet 7 est engagé par son extrémité libre 7a dans la boucle 7b et il est possible d'immobiliser cette extrémité libre 7a au niveau de resserrement souhaité par le jeu d'un gland de blocage de type connu 15.The
On comprend que ce qui vient d'être décrit en supposant que la face 1 soit mise en position supérieure, ce qui correspond à l'utilisation en position active du capuchon 4, peut être rigoureusement transposée dans le cas où inversement la face 1 est amenée en position inférieure et c'est la face 2 qui est en position supérieure ; dans ce cas c'est le capuchon 3 (en position inférieure) qui est amené en position active de resserrement autour de la tête de l'utilisateur, tandis que le capuchon 4 aura été préalablement désactivé compacté et ramassé au sommet de la face 2 comme on l'a vu pour le cas du capuchon 3 et comme illustré sur la figure 3.It is understood that what has just been described assuming that the face 1 is placed in the upper position, which corresponds to the use in the active position of the
L'invention permet donc de réaliser avantageusement un sac de couchage permettant d'utiliser de façon nouvelle les avantages et les propriétés du sac de couchage réversible, chaque face ayant des propriétés différentielles susceptibles d'être utilisées en fonction des circonstances, et en même temps l'intérêt et le confort d'un capuchon susceptible d'être mis en service, à partir de la face inférieure ; tandis que le capuchon opposé peut être désactivé et compacté en évitant ainsi de gêner ou de troubler la respiration du dormeur.The invention therefore makes it possible to advantageously produce a sleeping bag allowing the advantages and properties of the reversible sleeping bag to be used in a new way, each side having differential properties capable of being used depending on the circumstances, and at the same time the interest and comfort of a susceptible cap to be put into service, from the underside; while the opposite cap can be deactivated and compacted, thereby avoiding interfering with or disturbing the sleeper's breathing.
Bien plus le capuchon désactivé et replié sur la poitrine apporte une protection thermique supplémentaire.Even more, the deactivated and folded hood on the chest provides additional thermal protection.

and in that the same lace (7, 8), passing through the supple sleeve (5, 6) provided on a hood, extends in the supple sleeve (9, 10) disposed transversely on the top of the opposite face, with the result that this same lace makes it possible both to tighten the hood around the user's head and at the same time to tighten the upper opening of the bag around the user's neck by contraction of that face of the bag opposite the hood placed in active position. - Sleeping bag according to Claim 2,
characterized in that each lace (7, 8) passing successively through a supple sleeve (9, 10) at the top of a face of the bag and extending in the supple peripheral sleeve (5, 6) around the opposite hood, comprises a free end (7a, 8a) to allow cumulative tightening of the edges of the hood (4) brought into active position and of the top of the opposite face (1) of the bag placed in upper position, the opposite end (7b) of this lace being blocked, for example by stitching, at the end of its receiving sleeve (9b). - Sleeping bag according to Claim 3,
characterized in that the blocked end (7b, 8b) of this lace (7, 8) extends outside its receiving sleeve to form a fixed loop adapted to receive in position of engagement the free end (7a, 8a) of this lace.
