    • Encased coil innersprings with alternating spring coil orientations utilize a common coil configuration and a uniform encasement or pocket configuration, and wherein the coils have an asymmetrical configuration and the vertical end-up orientation of the coils that is alternated or otherwise varied. Selected coils in different areas or patterns in the array of pocketed coils that form the spring core are inverted, relative to a support surface of the spring core, within the individual pockets. The inverted coils have spring characteristics including spring rate, stiffness and initial deflection force which are different from the spring characteristics of the non-inverted coils due to the asymmetry of the coils along a longitudinal axis.
    • 具有交替的弹簧线圈取向的带有内圈的内圈弹簧利用公共线圈构造和均匀的包装或口袋配置,并且其中线圈具有非对称配置,并且线圈的垂直端向定向被交替或以其他方式改变。 形成弹簧芯的袋状线圈阵列中的不同区域或图案中的选定线圈相对于弹簧芯的支撑表面在各个口袋内被倒置。 倒置的线圈具有包括弹簧刚度,刚度和初始偏转力的弹簧特性,这些特性与不反转线圈的弹簧特性不同,这是由于线圈沿着纵向轴线的不对称性。
