Abstract
A vehicle seat, including two links movable for adjustment in height of the seat, is provided with a reinforcing transmission shaft. The reinforcing transmission shaft is rotatably connected between two frame members of seat cushion frame in the seat, while extending through the two links. Further, two pinions are fixed on the respective two end portions of the reinforcing transmission shaft and respectively meshed with two gear portions defined in the respective two links. With such arrangement, in the case of rear-end collision, most of great load applied to the links is transmitted, via the reinforcing transmission shaft, pinions and gear portions, to each of the two frame members, thereby preventing deformation of one of the two links to avoid lowering of the seat or inclination of one side of the seat as found in a rear-end collision case.
