Abstract:
1. An electromechanical brake booster comprising: a muscular force transmitting element by means of which it is possible to use muscular force to actuate a brake master cylinder; an electromechanical actuator by means of which it is also possible to actuate the brake master cylinder; at least two return springs that move the brake booster back to a starting position after an actuation, including a first return spring that returns the muscular force transmitting element and a second return spring that returns the actuator; and a telescoping booster element for transmitting an actuator force of the electromechanical actuator to a piston of the brake master cylinder, wherein the telescoping booster element is composed of an inner tube and an outer tube; and wherein the first return spring of the at least two return springs presses against the inner tube and the second return spring of the at least two return springs presses against the outer tube.
