ABSTRACT:
An adjustable lumbar assembly for a vehicle seat is provided with a wireframe for attachment to a frame of the seat. The wireframe has a pair of spaced apart side members. A flexible lumbar support band has a pair of outboard portions affixed to the side members, a pair of lateral portions extending inboard from the outboard portions and pivotally connected to the outboard portions offset from the side members. A central portion of the support band is pivotally connected to the lateral portions. A cable assembly is mounted to the outboard portions for extension and retraction of the lateral portions and the central portion for providing adjustment of the lumbar assembly. A method for manufacturing an adjustable lumbar assembly is provided by forming a wireframe with the side members, inserting the wireframe into a mold, and molding a flexible lumbar support band to the wireframe side members.
