Fiber mass with side coil insertion and method

摘要

A resilient structure having a fiber batt with coil springs disposed therein and respective coil spring paths. Each of the coil spring paths extending from a respective coil spring and having a profile similar to a cross-sectional profile of the respective coil spring taken in a plane parallel to a length of the coil spring. A method is also provided for heating the coil springs and inserting the coil springs into a side wall of the fiber batt to produce the coil spring paths that have a profile similar to a cross-sectional profile of the respective coil spring taken in a plane parallel to a length of the coil spring.
