ABSTRACT:
A transmission apparatus for permitting a seat occupant to selectively and remotely adjust distinct comfort features of a dual-function comfort mechanism corporated into a seating assembly. The transmission apparatus has a dual-positioned control device for defining a first mode position permitting selective actuation of a first cable assembly for causing corresponding adjustment of a first comfort feature. The transmission apparatus further defines a second mode position permitting selective actuation of a second cable assembly for independently adjusting a second comfort feature. The dual-position control device is movably supported within the transmission apparatus and is configured and arranged to be positively located and retained in either of the first or second mode positions for eliminating any lost motion therebetween.
