Tread step seal assembly for a tread system of a vehicle
A modular tread step seal assembly includes a tread step module which, using a drive unit, is movable along a movement axis from a retracted position in the direction of an extended position and vice versa. The tread step module has a tread surface extending in a tread surface plane oriented parallel to the movement axis and a tread step module front edge at a front end directed towards the outside of the vehicle. The assembly includes a sealing strip attached to the tread step module front edge and extends along the same, substantially in a sealing strip plane. The sealing strip and tread step module define, perpendicularly to the movement axis, a vertical assembly height. The sealing strip and tread surface are disposed at an angle to each other. The wherein assembly height and the angle between the sealing strip and the tread surface are adjustable via a modular mechanism.
