INFLATABLE STRUCTURE
First Claim
1. An inflatable structure, comprising:
- two fabric bodies, wherein each fabric body has an inner surface and an outer surface;
a solvent-based hydrophilic and vapor-transmissible plastic layer applied over the inner surfaces of the fabric body;
a low-modulus hydrophilic and vapor-transmissible plastic layer provided over the solvent-based hydrophilic and vapor-transmissible plastic layer;
a low-melting-point hydrophilic and vapor-transmissible plastic layer provided over the low-modulus hydrophilic and vapor-transmissible plastic layer;
wherein once all the layers are applied onto the inner surfaces of the fabric bodies, the inner surfaces of the fabric bodies are bonded together to form at least one continuous S-shaped bonding channel and an inflatable space is formed and enclosed by the S-shaped bonding channels, and areas on the outer surface at two opposite sides of the fabric bodies are bonded together to limit an inflated overall thickness of the fabric body, and the S-shaped bonding channel is formed at two ends with a closed circular bonding line each; and
an inflating valve provided on the fabric body to communicate with the inflatable space, so that air is supplied into or released from the inflatable space via the inflating valve;

Abstract
An inflatable structure includes a fabric body having three hydrophilic and vapor-transmissible plastic layers sequentially applied over an inner surface thereof, and including at least one continuous S-shaped bonding channel, along which areas on an outer surface of the fabric body at two opposite sides thereof are bonded together. The three hydrophilic and vapor transmissible plastic layers are lightweight, waterproof, vapor transmissible, and warm; and the S-shaped bonding channel has small width to allow increased inflatable space in the fabric body. The continuous S-shaped bonding channel has two ends formed into two closed circular bonding lines to avoid damage of the inflatable structure by stress concentrated at the bonding line.
