First Claim
1. A vehicle seat pressure sensor comprising:
- a light source;
a non-fiber optical polymer sheet of non-woven flexible optical polymer material having a first surface with a peripheral edge surrounding the first surface aligned with the light source such that light emitted from the light source projects into the optical polymer sheet through the peripheral edge;
a boundary layer disposed along the first surface of the optical polymer sheet; and
a detection unit disposed relative to the optical polymer sheet to detect changes in attenuation of light emitted from the peripheral edge of the optical polymer sheet in response to elastic deformation of the boundary layer and the optical polymer sheet.

Abstract
A vehicle seat pressure sensor includes a light source, a non-fiber optical polymer sheet, a boundary layer and a detection unit. The non-fiber optical polymer sheet is composed of non-woven flexible optical polymer material and has a first surface with a peripheral edge surrounding the first surface. The peripheral edge of the optical polymer sheet is aligned with the light source such that light emitted from the light source projects into the optical polymer sheet through the peripheral edge. The boundary layer is disposed along the first surface of the optical polymer sheet. The detection unit is disposed relative to the optical polymer sheet to detect changes in attenuation of light emitted from the peripheral edge of the optical polymer sheet in response to elastic deformation of the boundary layer and the optical polymer sheet.
