the movable door element ( 4 , 4 a , 4 b ) is a door leaf.

2. The door safety system ( 3 ) as claimed in claim 1 and wherein the electrical energy store ( 12 ) of the safety component ( 10 ) is a rechargeable battery pack with at least one rechargeable battery cell.

3. The door safety system ( 3 ) as claimed in claim 1 and wherein the safety component ( 10 ) and the supply component ( 11 ) are designed to electrically charge the electrical energy store ( 12 ) of the safety component ( 10 ) wirelessly, in the closed state of the door ( 2 ).

4. The door safety system ( 3 ) as claimed in claim 1 and further comprising:
a contact element arranged on the movable door element ( 4 , 4 a , 4 b ) and electrically connected to the safety component ( 10 ); and
a mating contact element arranged on the immovable door frame ( 5 ) and the mating contact element is electrically connected to the supply component ( 11 ) and contacts the contact element on the movable door element ( 4 , 4 a , 4 b ) when the door ( 2 ) is in the closed state; and
the safety component ( 10 ) and the supply component ( 11 ) electrically charge the electrical energy store ( 12 ) of the safety component ( 10 ) of the door ( 2 ).

5. The door safety system ( 3 ) as claimed in claim 1 and wherein the safety component ( 10 ) and the controller ( 22 ) wirelessly interchange electrical data signals with one another.

6. The door safety system ( 3 ) as claimed in claim 5 and wherein the safety component ( 10 ) and the controller ( 22 ) wirelessly interchange the electrical data signals using a radio standard.

7. A door ( 2 ), in particular an automatic door ( 2 ) of a transport means ( 1 ) comprising:
an immovable door frame ( 5 ) carried by the transport means ( 1 );
a movable door element ( 4 , 4 a , 4 b ) which comprises a door leaf, and the movable door element ( 4 , 4 a , 4 b ) is at least partially movably carried by the immovable door frame ( 5 ); and
a door safety system ( 3 ) having,
a safety component ( 10 ) arranged on the movable door element ( 4 , 4 a , 4 b ) of the door ( 2 ), and the safety component ( 10 ) has an electrical energy store ( 12 ), 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 supply component ( 11 ) which is arranged on the immovable door frame ( 5 ) of the door ( 2 ) and the supply component supplies the safety component ( 10 ) with electricity, and wherein
