Abstract (en)
A self-inflating member (10) is provided. The self-inflating member comprises a first flexible layer (1), a second flexible layer (2), a contracting element (5), a check valve (3) and a first supporting element (4a). The first and second flexible layers are connected to each other such that a cavity is formed between the first and second flexible layers. At least one of the first and second flexible layer comprises the check valve, such that the check valve creates a fluid connection between the cavity and the ambient environment. The contracting element is connected to the first and second flexible layers in at least a first and a second position (L', L''), such that contraction of the contracting element moves the first and second positions closer to each other. The first supporting element assists in supporting at least one of the first and second flexible layers, such that the cavity is expanded, which causes fluid from the ambient environment to flow through the check valve and into the expanded cavity.
