1. A safety apparatus for an elevator having an elevator car having a presence determination device for determining that only one person is present in the elevator car, having a position determination device for determining that the person is in a lying or crouching position and a length of time since the lying or crouching position occurred, and having a relay device for relaying a signal to a supervisory authority,
wherein the relay device relays the signal when the presence determination device determines that there is only a single person in the elevator car and the position determination device determines that the person is in the lying or crouching position and a specific length of time has elapsed since the lying or crouching position occurred, and
wherein the position determination device determines that the person is in the lying or crouching position by virtue of there having been a drop below a first threshold for a height of the person.
