Abstract: A lighting module with an efficient heatsink. The heatsink may include a base conducting portion, side fins, and a center structure. The side fins may extend away from the base portion in such a way that the distance between the fins and the center structure may vary as they may extend away from the base portion. Warm air near the base conducting portion may rise due to natural convection buoyancy, in which vertical narrowing passages may result in the passive air flow increasing in velocity as it may travel near the narrowing surface area of the heatsink improving heat transfer, and as the side fins and center structure air passages widen, the air velocity may reduce as the warm air may be distributed above heatsink.

Abstract: A air bag module comprises an inflator, a unitary polymeric housing, and an air bag retainer of the same or similar material. The housing has integral walls forming an inflator chamber which include an inflator mounting stud aperture, a plurality of integral supports for the inflator, an integral peripheral rim forming an airbag chamber, and an integral upper wall having inflator gas diffuser apertures. An inflator stud fastener secures the inflator to the housing. The retainer and housing have integral cooperating fasteners for securing the retainer to the housing. A polymeric cover closes the retainer and confines the attached air bag. The housing and retainer are formed of the same recyclable material such that the air bag assembly can be recycled by simply removing only the stud fastener and the inflator. Several embodiments of the housing, retainer and fasteners are disclosed. In one embodiment, an inflator gas diffuser that is integral with the housing.
