Patent Images
1. A method of forming at least one style feature line in a cover element for seat upholstery, comprising the steps of:
- depositing foam in a viscous state on a support element to create an assembly comprising the support element and the foam in the viscous state;
polymerizing the foam by placing the assembly comprising the support element and the foam in the viscous state in a mold having a matrix and a punch, the matrix comprising one or more matrix ribs, each of the one or more matrix ribs for defining a style feature line and the punch comprising two punch ribs for each of the one or more matrix ribs, each of the one or more matrix ribs aligned between the two punch ribs.
