Assembly for an electromechanical brake booster of a vehicle braking system, brake booster with such an assembly, and vehicle braking system with such an assembly

An assembly (100) for an electromechanical brake booster (200) of a vehicle braking system (1000), the assembly comprising:

• a housing (160) which has a longitudinal axis (L) and can be loaded with an electromechanically generated actuating force;
• an output element (150) extending away from the housing (160) and configured for transmitting the actuating force to a brake cylinder (300) of the vehicle braking system (1000), the output element comprising a shaft (152) and a head (156) facing the housing (160), an outer diameter of the shaft (152) being smaller than an outer diameter of the head (156), a curved transitional surface (154) of the output element (150) being arranged between the shaft (152) and the head (156) such that a diameter of the output element (150) increases steplessly from the shaft (152) to the head (156);
• an elastic element (190) which is supported on the housing (160) and configured to move the housing (160) away from the brake cylinder (300) into a starting position;
• and
• a guide (180) which is arranged on the housing (160) for the output element (150) and is configured to guide an angular deflection of the output element (150) with respect to the longitudinal axis (L) of the housing (160), the guide (180) being configured to cooperate with h curved transitional surface (154) of the output element (150) in a region which, in the radial direction with respect to the longitudinal axis (L) of the housing (160), lies closer to the outer diameter of the shaft (152) than to the outer diameter of the head (156).
