Abstract
A cross wire linked between master and slave lock bars of a vehicle seat adjuster assembly has a normally fixed length, but can lengthen when needed to accommodate a wide build condition of the parallel seat tracks. The fixed length of the cross wire is set so as to accommodate every condition but for master lock bar opening at wide build, when the slave lock bar will fully open before the master lock bar has fully opened. At that point, and only at that point, a central, integral coil spring in the cross bar, which is preloaded to match the fully open return spring force of the slave lock bar, stretches and allows the whole cross wire to effectively lengthen. The master lock bar can then be fully opened without overstressing the wire.
