Absorbent article with fit enhancement system
First Claim
1. An absorbent article for fitting about a wearer'"'"'s body, the absorbent article having longitudinal and lateral centerlines, which respectively define a longitudinal and a lateral direction, the absorbent article comprising:
- a containment assembly having first and second end edges, said containment assembly comprising a liquid pervious topsheet, a liquid impervious backsheet joined with said topsheet, and an absorbent core positioned intermediate said topsheet and said backsheet;
a first fit panel having a first waist edge and a first chassis edge longitudinally opposite said first waist edge, said first chassis edge being joined to said containment assembly adjacent said first end edge of said containment assembly, said first fit panel being elastically extensible with a vector component in the longitudinal direction, said elastic extensibility providing a body contact force;
a first waist feature being joined to said first fit panel adjacent said first waist edge, said first waist feature being elastically extensible with a vector component in the lateral direction; and
a fastening system disposed on said first waist feature for maintaining lateral tension through at least a portion of said first waist feature.

Abstract
Absorbent articles, such as disposable diapers, incontinence briefs, diaper holders, training pants, and the like having fit panels that improve body contact of the containment assembly, with resulting improved fit, are provided. The fit panels have longitudinal elastic extensibility that provides a body contact force causing the containment assembly to have improved contact with a wearer throughout the full range of wearer motions. The longitudinal elastic extensibility of the fit panel also allows the absorbent article to adapt to the change in body rise dimensions that occurs during normal movement. An alternative embodiment of the invention also provides a stretchable attachment component allowing the waist feature of the absorbent article to be attached to the waistband of a wearer'"'"'s clothing in a manner such that it can stretch and contract with the waistband while remaining attached.
