Tread step seal assembly for a tread system of a vehicle

A modular tread step seal assembly for a tread system implemented in a vehicle, the assembly comprising:

• a tread step module, which, using a drive unit, is moved along a movement axis (A) from a retracted position in the direction of an extended position and vice versa, wherein the tread step module has a tread surface extending in a tread surface plane oriented parallel to the movement axis (A), and wherein the tread step module has a tread step module front edge at a front end directed towards the outside of the vehicle,
• a sealing strip, which is attached to the tread step module front edge and extends along the tread step module front edge substantially in a sealing strip plane, wherein the sealing strip and the tread step module define, perpendicularly to the movement axis (A), a vertical assembly height (H), and wherein the sealing strip and the tread surface are disposed at an angle (B) to each other,
• wherein the assembly height (H) and the angle (B) between the sealing strip and the tread surface are adjusted using a modular mechanism.
