## Abstract

An inflatable body includes an elongate chamber delimited by two substantially parallel main walls and defining at least a portion of a base suitable for holding a person laid down thereon, the chamber being extended, integrally, on both sides of the base, beyond a transition area where the main walls are close to each other, by two raised lateral strips extending along at least the base portion, so as to laterally flank the person, wherein the main walls are braced by a plurality of drop stitch links, and at the location of the transition area, the inflatable body has seams bringing the main walls together, thereby causing a fold between the base and each of the raised lateral strips, with the seams being covered by a sealed lining wall.

## Claims

### Claim 1

An inflatable body having a direction of elongation and including an elongate chamber delimited by two substantially planar main walls, approximately parallel and gastight, said chamber defining at least a portion of a base suitable for holding a person laid down in said direction of elongation, the chamber being extended, integrally, on both sides of the base, beyond a transition area where said main walls are close to each other, by two raised lateral strips extending along at least said portion of said base, so as to laterally flank the person, wherein:
said main walls are braced by a plurality of drop stitch links, and,
at the location of the transition area, the inflatable body has at least one seam that brings the main walls together, thereby causing a fold between the base and each of the raised lateral strips, with each said seam being covered by a sealed lining wall.

### Claim 2 (depends on 1)

The body according to claim 1, wherein there are a plurality of seams and the seams are discontinuous, thereby promoting a passage of an inflation gas between the base and each of the raised lateral strips.

### Claim 3 (depends on 1)

The body according claim 1, wherein each said raised lateral strip has a clamp that promotes raising of each said strip with respect to the base.

### Claim 4 (depends on 3)

The body according to claim 3, wherein the clamp is formed by a notch produced in one of the lateral strips, and adjacent edges are covered by a sealed lining and assembling wall.

### Claim 5 (depends on 1)

The body according to claim 1, wherein the base is connected to said lateral strips at a location of the transition area along two non-rectilinear lines having at least one clamped inflection.

### Claim 6 (depends on 5)

The body according to claim 5, wherein, at a location of said inflection, each said lateral strip has said at least one clamp inflection.

### Claim 7 (depends on 1)

The body according to claim 1, wherein an entirety of the base and the lateral strips is integral, and, in an inflated state of the body, pressure in each said lateral strip is at least 0.4×105 Pa.

### Claim 8 (depends on 1)

The body according to claim 1, further including along an external surface of each said lateral strip, a plurality of lifting and carrying handles; a deflation opening; and a device for inflation with a gas cartridge attached to one of the body and a valve suitable for being connected to a compressed gas supply independent of the body.

### Claim 9 (depends on 1)

The body according to claim 1, wherein the body has a maximum volume to be inflated of 120 dm3.

### Claim 10 (depends on 1)

The body according to claim 1, wherein the body is free of any reinforcement for the base and the lateral strips, with the inflation pressure ensuring the rigidity of the lateral strips and the planarity of the base, when in the inflated state.

### Claim 11 (depends on 1)

The body according to claim 1, wherein the flexible links have a common length at the location of the base, the transition areas and the two raised lateral strips.
