Abstract: Blow molded plastic structures are provided for use in various structures such as, but not limited to, tables, chairs, walls, backboards, storage bins, sports equipment and the like. The blow molded plastic structure has a first surface and a second surface extending between a first end and a second end and forming a chamber there between. A plurality of depressions is formed on the second surface and extends into the chamber. The depressions are usually unitary structures formed by a depression wall. Generally, the steeper the depression wall, the more strength is provided to the structure. In addition, where the plurality of depressions has a low profile and a greater density, increased strength is provided to the structure. The depressions may or may not be joined to the first surface.

Abstract: An inflator is provided that can reduce the occurrence of virtual and masked leaks in inflator testing. The inflator may have an outer wall surrounding a main internal compartment containing compressed inflation gases. Additionally, the inflator may have a pyrotechnic assembly containing a generant, or pyrotechnic material, and an initiator configured to ignite the pyrotechnic material upon receipt of an electric signal from a vehicle's electrical system. The initiator may be separated from the pyrotechnic material, and from the compressed gases, by a pressure dome that effectively creates a cavity around the initiator. The initiator may be accessible to outside contact through an opening in the outer wall. An insert may be positioned around the initiator to control flows of gas leaving the cavity through the opening.
