1. A door safety system (3) for a door (2), having a movable door element (4, 4a, 4b) and an immovable door frame (5), comprising:
a safety component (10) arranged on the movable door element (4, 4a, 4b) of the door (2), and the safety component (10) has an electrical energy store (12); and
a supply component (11) which is arranged on the immovable door frame (5) of the door (2) and the supply component (11) supplies the safety component (10) with electricity; and wherein
the electrical energy store (12) autonomously supplies the safety component (10) with electrical energy when the door (2) is in an open state relative to the immovable door frame (5); and wherein
the safety component (10) and the supply component (11) electrically charge the electrical energy store (12) of the safety component (10) when the door (2) is in a closed state relative to the immovable door frame (5); and wherein
the safety component comprises at least one of a light barrier, a light curtain, a light grid a contact safety strip, an optical signal generator, an acoustic signal generator, or a haptic signal generator; and
a controller (22) for controlling and or monitoring the safety component (10); and
the controller (22) is arranged on the immovable door frame (5); and wherein
the safety component (10) and the controller (22) operatively communicate bidirectionally and wirelessly with one another; and wherein
the movable door element (4, 4a, 4b) is a door leaf.
