Abstract
A buffer device for use to the seats of vehicles provided with a pair of links arranged parallel to each other between floor brackets and an upper frame of the seat to form a parallel linkage mechanism. The upper ends of the links are swingably attached to the upper shafts and a connector rod are supported by the upper shafts at both ends thereof, so that a second parallel linkage mechanism can be formed by the connector rod and a line passing through the centers of the upper shafts. The connector rod prevents the links from being inclined independently of the other when the links are inclined nearly horizontal, thereby enabling the device to be made stable when the links are nearly horizontal.
