Seat e.g. middle or rear seat, for van, has four-joints rotating cushion around pole, where distance of pole by hip point in usage position is smaller than distance of pole from line by fifth and sixth joints

摘要

The seat (1) has four-joints (A-D) rotating a cushion (3) around a velocity pole arranged in a distance of a vertical line by a hip point of the seat. The four-joints are arranged above a backrest rotation axis (L) in a usage position, and a coupler is hinged at a seat cushion by a fifth joint (E). A sixth joint (F) defines a straight line to, which the pole is arranged in a distance and the backrest axis is arranged in a distance. The distance of the pole by the hip point in the usage position is smaller than the distance of the pole from the line by the fifth and sixth joints.
