The present invention relates to a pneumatic structure (10) comprising an inextensible body (12) defining at least a network of internal cavities (14), each cavity having a closed contour in at least one section of the cavity

Each cavity being suitable for being pressurized so as to change the inextensible body from a rest configuration to at least one pressurized configuration,

Inextensible body having, in each pressurized configuration, a macroscopic metric different from its macroscopic metric in the rest configuration,

Each cavity being formed of at least two substantially rectilinear channels, each channel being fluidly connected to at least one of the other channels, the two said channels forming a heading change angle,

Each cavity comprising at least one non-zero heading change angle, in particular at least three non-zero heading change angles.

A mandrel for use in welding an air mattress having a top layer, bottom layer and at least one baffle joining the top layer and bottom layer, the mandrel includes a central mounting block; a baffle locating pin on a top surface of the central mounting block for securing the baffle to the central mounting block; a conductive sealing surface positioned along an edge of the central mounting block; a stop block positioned on the top surface of the central mounting block adjacent the sealing surface; and a bumper mounted to the central mounting block.

A support system includes two cushions. The first cushion is divided into a plurality of bladders filled with a fluid, the bladders being connected by fluid interconnections. The second cushion is coupled to the first cushion. The second cushion is also divided into a plurality of bladders filled with a fluid, the bladders connected by fluid interconnections. When a force is applied to one of the plurality of bladders, a reactionary force is produced in a different one of the plurality of bladders in the same respective cushion.

Disclosed is a system for a combination bag, mat, and flotation device. The system includes a rectangular elongated mat having an external surface, internal surface, a mat section first side and second side, and a mat section first side and second side. A pair of flotation devices are attached to the mat section first side and second side. Each flotation device has an internal air compartment, inflation nozzle, and attachment element, and when inflated, allow the mat to be used as a flotation device. A zipper is disposed on the perimeter of the mat. A first fastener in attachment proximate to the mat section first side and a second fastener in attachment proximate to the mat section second side. The first fastener and second fastener are configured to removably mate with each other. When the mat is folded so that the first fastener and second fastener are mated and the zipper is sealed, the mat forms a bag configuration.
