Abstract
Official abstract text for this publication.
A vehicle lower portion structure is provided with electromagnetic wave emitting components that are disposed at a rear surface side of a floor panel provided in a lower portion of a vehicle, and a carpet component that has a backing layer in which is dispersed a magnetic material, and a carpet pile that is provided on a front surface side of the backing layer, and that is disposed at a front surface side of the floor panel.
First claim
Opening claim text (preview).
What is claimed is: 1. A vehicle lower portion structure comprising: electromagnetic wave emitting components that are disposed at a rear surface side of a floor panel provided in a lower portion of a vehicle; and a carpet component that has a backing layer in which is dispersed a magnetic material, and a carpet pile that is provided on a front surface side of the backing layer, and that is disposed at a front surface side of the floor panel. 2. The vehicle lower portion structure according to claim 1 , wherein a density of the magnetic material dispersed in portions of the backing layer that correspond to the electromagnetic wave emitting components is higher than a density of the magnetic material dispersed in other portions of the backing layer. 3. The vehicle lower portion structure according to claim 1 , wherein the magnetic material is only dispersed in portions of the backing layer that correspond to the electromagnetic wave emitting components. 4. The vehicle lower portion structure according to claim 1 , wherein the backing layer is divided into a first portion that corresponds to positions of the electromagnetic wave emitting components, and a second portion that does not correspond to the positions of the electromagnetic wave emitting components, and the magnetic material is only dispersed in the first portion. 5. The vehicle lower portion structure according to claim 1 , wherein the electromagnetic wave emitting components comprise at least one of a drive apparatus of the vehicle, high voltage wiring that is connected to the drive apparatus, and a battery pack.
