Inflatable device for use as a mattress or as a support for a mattress

An inflatable device for use as a mattress or as a support for a mattress comprising:

• a flexible top layer (1);
• and
• a flexible bottom layer (2);
• and wherein
• a first longitudinal edge of the flexible top layer (1) and a first longitudinal edge of the flexible bottom layer (2) are connected to a first flexible longitudinal side layer (3);
• and wherein
• a second longitudinal edge of the flexible top layer (1) and a second longitudinal edge of the flexible bottom layer (2) are connected to a second flexible longitudinal side layer (4);
• and wherein
• a first transverse edge of the flexible top layer (1) and a first transverse edge of the flexible bottom layer (2) are connected to a first flexible transverse side layer (5);
• and wherein
• a second transverse edge of the flexible top layer (1) and a second transverse edge of the flexible bottom layer (2) are connected to a second flexible transverse side layer (6);
• characterized in that
• said inflatable support device comprises a plurality of inflatable transverse chambers (8) arranged in series along the longitudinal direction of said inflatable device;
• and wherein
• each inflatable transverse chamber (8) is delimited by a portion of the flexible top layer (1), by a portion of the flexible bottom layer (2), by two flexible transverse vertical separators (7) and by a portion selected from the group consisting of a portion of the first flexible longitudinal side layer (3) and of a portion of the second flexible longitudinal side layer (4);
• and wherein
• a filling channel (11) is arranged inside said inflatable device in communication with the plurality of inflatable transverse chambers (8);
• and wherein
• a filling fluid entry mouthpiece (12) is connected to said filling channel (11) and a filling valve (13) is connected to said filling fluid entry mouthpiece (12);
• and wherein
• the flexible top layer (1) is arranged on a slanted plane relative to the plane of the flexible bottom layer (2), when the inflatable device is inflated.
