Brake actuating element coupling device

A brake actuating element coupling device, comprising:

• a first input rod component which is connected or can be connected directly or indirectly to a brake actuating element in such a way that the first input rod component is adjustable, using a driver braking force exerted on the brake actuating element and transmitted to the first input rod component, from a first starting position in a braking direction to a master brake cylinder that is part of the device or is external;
• a second input rod component;
• and
• a locking mechanism, wherein the second input rod component is fastened to the first input rod component via the locking mechanism, which is in a locking functional mode, in such a way that the second input rod component can be adjusted together with the first input rod component in the braking direction and the driver braking force can be transmitted directly or indirectly from the second input rod component to at least one adjustable piston of the master brake cylinder, and, when the locking mechanism is in a non-locking functional mode, the second input rod component is adjustable relative to the first input rod component in the braking direction;
• wherein the locking mechanism is configured such that the locking mechanism can be transferred from the non-locking functional mode to the locking functional mode by an adjustment of the first input rod component from the first starting position by at least a specified first minimum adjustment travel.
