Abstract
In a vehicle seat, two front links and two rear links are pivotally connected between a seat cushion frame and a floor of vehicle. One of the two front links is of a sector shape having an arcuate gear region meshed with a drive pinion. Or alternatively, both of the two front links may be of such sector gear configuration, such that one front link is engaged with the drive pinion and the other front link engaged with a free-to-rotate pinion. Hence, both two front links are robust enough to withstand an excessive great load in the case of rear-end collision. By contrast, the two rear links are simply prone to deformation by the excessive great load. Accordingly, the excessive great load is to be intensively exerted upon those two rear links which will in turn be deformed quickly to absorb a corresponding excessive great impact.
