摘要： A lift and tilt mechanism (1) is disclosed, comprising a base frame (10) and an upper lever arm (2) rotatably connected to each other by a lower lever arm (3) and a control rod (4), wherein a rotating arm (6) is rotatably connected to an upper lever arm (2), a torque arm (9) is rotatably connected to a lower lever arm (3), and the rotating arm (6) and the torque arm (9) are rotatably connected to each other, and wherein a power source (8) is rotatably connected to the upper lever arm (2) and directly or indirectly to the connection joint (19) for the rotating arm (6) and the torque arm (9), in such a way that an extension of the length of the power source (8) causes its suspension point (11) on the upper lever arm (2) to move in an substantially vertically direction, whereby the upper lever arm (2) is tilted towards a more upright position. Furthermore, a tilt system (21) comprising such a mechanism (1) is disclosed.
