Abstract
An inflatable safety arrangement for a safety device in a motor vehicle, especially an in-seat device to prevent “submarining” comprises an inflatable unit formed of at least one pre-formed plastically deformable element which initially defines an inwardly directed recess partially filling a void defined within the interior of the inflatable unit. On actuation of a gas generator the inwardly directed protrusion becomes an outwardly directed protrusion. The inwardly directed protrusion may have two substantially planar walls, one of which carries an outwardly extending projection.
Claims7
An inflatable arrangement comprising an inflatable unit formed of at least one pre-formed plastically deformable element which forms part of the periphery of a chamber adapted to be inflated, there being a gas generator to supply gas to the chamber, the said plastically deformable element initially spanning across a void and having an inwardly directed protrusion, the protrusion at least partially filling the void, the arrangement being such that on actuation of the gas generator the inwardly directed protrusion will become an outwardly directed protrusion.
