1. A method for manufacturing a webbing (20) for a seat belt system (12) in a vehicle (10), comprising the steps of:
a) forming the webbing (20) using a first yarn (30) and a second yarn (32), the first yarn (30) and the second yarn (32) reflecting light in the spectrum invisible to humans with different intensity, wherein the first and second yarns (30, 32) form a pattern (36), and
b) overdying at least the portion of the webbing (20) that includes the pattern (36) with a material (34) that is opaque in the spectral range visible to humans so that the pattern (36) under the material (34) is invisible to humans and the webbing (20) has a homogenous appearance to humans, the material (34) being at least partially transparent in the spectrum invisible to humans, each overdyed portion of the webbing (20) being covered and at least partially dyed by the material (34).
