An aqueous polymer dispersion comprises rubber particles and polymer particles having a reinforcing action. To increase the luminous efficiency, the cross-sectional area of the radiation-emitting active region is smaller than the cross-sectional area of the window layer available for the decoupling of light. The method has a step of determining at least one object property of an object in an area in the driving direction ahead of the vehicle by using surroundings data from the surroundings detection attachment. In another embodiment, the relative movement is accommodated by slippage along a friction surface interposed between the actuator shaft and the motor. The upper steering shaft is inserted in the upper bracket and then fixed to the lower steering shaft. A plurality of corner connectors is configured to engage one of the cover slots and the side isolation barrier slots.
