| 摘要 | A vehicle seat (10) is equipped with a seat frame composed of a sub-frame (16) and a rod (30) provided between certain regions of the sub-frame. The rod is equipped with a minor vibration damping portion (34) that maintains rigidity of the seat frame when the seat frame is displaced by a large amount and suppresses an increase in rigidity of the seat frame when the seat frame is displaced by a small amount to reduce the level of minor vibrations in the vehicle seat. | ||

| 主权项 | 1. A vehicle seat comprising: a seat frame having a sub-frame and a cantilevered rod provided between certain regions of the sub-frame; a minor vibration damping portion that is configured to maintain rigidity of the seat frame when the seat frame is displaced by a large amount and to suppress an increase in rigidity of the seat frame when the seat frame is displaced by a small amount, which thereby reduces a level of minor vibrations; wherein the minor vibration damping portion is constructed such that the rod and the sub-frame or intermediate portions of the rod are spaced apart from each other when the seat frame is displaced by the small amount, the rod and the sub-frame or the intermediate portions of the rod directly abut on each other when the seat frame is displaced by the large amount; and the minor vibration damping portion is constructed as a clearance provided between a tip of the rod and the sub-frame or between the intermediate portions of the rod. | ||
