| 摘要 |
The present invention embodies a seat cushion and base which are made of metal and have oppositely disposed triangular plates attached thereto and connected by pivot pins which are axially aligned on the center of the cushion and base forming a hinge arrangement. This permits the lateral tilting of the seat cushion when the vehicle is tilted thereby maintaining the cushion in normal horizontal position. A pair of rams are disposed between the base and the cushion connected by a hydraulic line which conducts fluid from one ram to the other when the load of the occupant shifts due to the vehicle tilting to have the high side of the cushion move downwardly to maintain it in horizontal position.
