CA 2366098

The inventive pneumatic mattress (1) is comprised of an air-tight cover (2) which is arranged in a top layer (7) and in a bottom layer (6), whereby the top layer (7) and bottom layer (6) are interconnected by a multitude of cross-members (3), for example, textile cross-members. A rear wall (4) is arranged outside of the air-tight area of the cover (2), however, it is enclosed by the top and bottom layers (7, 6). The rear wall (4) is fastened to the wall (5) using known means (5) such that the cover (2) does not require passages running therethrough. The cover (2) is comprised of a textile material which does not stretch easily and which is coated in order to render it air-tight. The cross-members (3) are also made of, for example, a textile material that does not stretch easily. For use, the pneumatic mattress (1) is inflated with compressed air for which a valve (9) is provided. The pneumatic mattress (1) can comprise an elevated edge (8) located on the edge opposite the wall(5). When not in use, the pneumatic mattress (1) can be deflated and stored, for example, in a bag (10).

L'invention concerne un matelas pneumatique (1) comprenant une enveloppe étanche à l'air (2), constituée d'une couche supérieure (6) et d'une couche inférieure (6), interconnectées par une pluralité d'entretoises (3) par exemple des entretoises textiles. Une paroi arrière (4) est montée en dehors de la zone étanche à l'air de l'enveloppe (2), mais est néanmoins enveloppée par la couche extérieure et par la couche intérieure (7,6). La paroi arrière (4) est fixée contre un mur (5) avec des moyens connus qui ne nécessitent pas l'aménagement de passages à travers l'enveloppe étanche à l'air (2). L'enveloppe (2) consiste en un matériau textile peu extensible, muni d'un revêtement étanche à l'air. Les entretoises (3) consistent également en un matériau peu extensible, par exemple un matériau textile. Pour fonctionner, le matelas (1) doit être sollicité par de l'air comprimé. A cet effet, il est prévu un clapet (9). Sur le bord opposé au mur (5), le matelas (1) peut comporter un bord augmenté (8). Lorsque ledit matelas (1) n'est pas utilisé, il peut être dégonflé et remisé dans un sac (10).
