The invention relates to a vehicle seat with a vertical axis pivoting function, said seat comprising a base (3), a rotating ring (4), a seat cushion frame connected to the rotating ring, a hinge mechanism allowing a rotation relative to the base about a main vertical axis (Z1) of the rotating ring, said seat having four pairs of retaining parts, each pair of retaining members comprises a first member (1) fixed to the base and a second member (2) fixed to the rotating ring. The first component and the second component are spaced apart in a normal mode of operation, and if an accident occurs in the vehicle, the first component and the second component are in contact with each other to prevent disengagement of the rotating ring, and the intermeshing lobes of the first component and the second component are engaged to prevent sliding of the second component relative to the first component.
本发明涉及具有垂直轴枢转功能的车辆座椅,所述座椅包括基座(3)、旋转环(4)、连接到旋转环的座垫框架、允许围绕旋转环的主垂直轴(Z1)相对于基座旋转的铰接机构,所述座椅具有四对保持部件,每对保持部件包括固定到基座的第一部件(1)和固定到旋转环的第二部件(2)。所述第一部件和第二部件在正常操作模式下间隔开,并且如果车辆发生事故,则第一部件和第二部件彼此接触以防止旋转环的脱离,并且第一部件和第二部件的相互啮合的凸起部被接合以防止第二部件相对于第一部件滑动。
