1. A brake booster coupling device, comprising:
a braking piston, which is at least partially displaceable in a brake master cylinder; an input piston, which is situatable on a brake input element so that the input piston is displaceable in the event of an operation of the brake input element from its starting position by a driver braking distance in a direction toward at least one of the braking piston and the brake master cylinder, wherein a force transmission between the input piston, which is displaced by a driver braking distance below a predefined threshold value, and the braking piston is prevented; a booster piston, which is situatable on a brake booster drive so that the booster piston is displaceable with the aid of the brake booster drive, at least in the case of a driver braking distance of the input piston below the predefined threshold value, so that the braking piston, which contacts the booster piston, is displaceable with the aid of the brake booster drive from a non-braking position into at least one braking position; and a contact element, which is situated on the braking piston, and which is at least one of displaced and deformed in the event of a displacement of the braking piston from the non-braking position into the at least one braking position so that a first contact surface of the contact element is transferred in relation to the braking piston in a direction toward a second contact surface of the input piston, the second contact surface of the input piston, which is displaced by a driver braking distance greater than the threshold value, contacts the first contact surface of the contact element so that a driver brake force is transmitted from the input piston, which is displaced by the driver braking distance greater than the threshold value, via the contact element to the braking piston, which is present in a position range including the non-braking position and the at least one braking position. |
