Abstract
A method for determining usability of a cover material as a cover of a vehicle seat component includes determining a fabric stretch requirement for the vehicle seat component; determining actual fabric stretch of the cover material; and comparing the actual fabric stretch with the fabric stretch requirement to determine whether the cover material is satisfactory for use with the vehicle seat component as the cover.
Claims14
A method for determining usability of a cover material as a cover of a vehicle seat component, the method comprising:
- determining a fabric stretch requirement for the vehicle seat component;
- determining actual fabric stretch of the cover material;
- and
- comparing the actual fabric stretch with the fabric stretch requirement to determine whether the cover material is satisfactory for use with the vehicle seat component as the cover, wherein the step of comparing the actual fabric stretch with the fabric stretch requirement is performed before proceeding to utilize the cover material in manufacturing of the vehicle seat component.
A method for selecting a cover material for use as a cover of a vehicle seat component, the method comprising:
- determining thickness of a foam sheet, if any, of the cover material;
- determining a component contour classification of the vehicle seat component;
- determining a minimum machine direction fabric stretch requirement, a minimum cross-machine direction fabric stretch requirement and a minimum diagonal fabric stretch requirement, based on the thickness of the foam sheet and the component contour classification, utilizing a look-up table that references foam sheet thickness and component contour classification;
- determining a maximum machine direction fabric stretch requirement, a maximum cross-machine direction fabric stretch requirement and a maximum diagonal fabric stretch requirement utilizing the look-up table;
- determining actual machine direction fabric stretch, actual cross-machine fabric stretch and actual diagonal fabric stretch of the cover material;
- comparing the actual machine direction fabric stretch with the minimum machine direction fabric stretch requirement and the maximum machine direction fabric stretch requirement;
- comparing the actual cross-machine direction fabric stretch with the minimum cross-machine direction fabric stretch requirement and the maximum cross-machine direction fabric stretch requirement;
- and
- comparing the actual diagonal fabric stretch with the minimum diagonal fabric stretch requirement and the maximum diagonal fabric stretch requirement.
A method for selecting a cover material for use as a seat cover of a vehicle seat, the method comprising:
- determining thickness of a foam sheet, if any, of the cover material;
- determining a vehicle seat contour classification of the vehicle seat;
- determining a minimum machine direction fabric stretch requirement, a minimum cross-machine direction fabric stretch requirement and a minimum diagonal fabric stretch requirement, based on the thickness of the foam sheet and the vehicle seat contour classification, utilizing a look-up table that references foam sheet thickness and vehicle seat contour classification;
- determining a maximum machine direction fabric stretch requirement, a maximum cross-machine direction fabric stretch requirement and a maximum diagonal fabric stretch requirement utilizing the look-up table;
- determining actual machine direction fabric stretch, actual cross-machine fabric stretch and actual diagonal fabric stretch of the cover material;
- comparing the actual machine direction fabric stretch with the minimum machine direction fabric stretch requirement and the maximum machine direction fabric stretch requirement;
- comparing the actual cross-machine direction fabric stretch with the minimum cross-machine direction fabric stretch requirement and the maximum cross-machine direction fabric stretch requirement;
- and
- comparing the actual diagonal fabric stretch with the minimum diagonal fabric stretch requirement and the maximum diagonal fabric stretch requirement.
