Abstract
A vehicle step includes a step member and first and second extending and retracting devices connected to the step member for moving it between extended and retracted positions. Each of the extending and retracting devices includes a mounting bracket adapted to be fixed to a vehicle body, a step bracket connected to the step member, first and second arms each defining a lower end rotatably connected to the step bracket and an upper end, and a third arm defining an upper end rotatably connected to the mounting bracket and a lower end rotatably connected to the upper end of the first or second arm. The upper end of the other of the first or second arm is rotatably connected to the mounting bracket. The vehicle step includes also driving devices that drive respectively the extending and retracting devices to move the step member between the extended and retracted positions.
