Vehicle floor tub having a laminated structure

摘要

A tub is configured for attachment to a vehicle floor to receive a collapsed vehicle seat therein. The tub is formed from a laminated sheet structure including two layers of cold rolled steel having a viscoelastic layer therebetween spanning the entirety of both steel layers. The tub body has a rim, side walls extending downward from the rim, and a bottom supported by the side walls. The tub body is approximately 10'' deep from the rim to the bottom. The laminated sheet structure has a bending rigidity between approximately 9.7 and 16.5 Nm to enable the forming of the side walls.
