wherein each of the least two portions ( 19 , 20 ) of the protection apparatus ( 18 ) have lateral arms ( 23 , 24 ); and

wherein struts ( 29 ) extending in the transverse direction of the attachment run between the lateral arms ( 23 , 24 ) of the at least two portions ( 19 , 20 ) of the protection apparatus ( 18 ), wherein a common covering tarpaulin ( 30 ) or a covering net ( 30 ) or a combination of a covering tarpaulin and a covering net ( 30 ) for all of the portions of the protection apparatus is arranged on the struts ( 29 ).

2 . The attachment according to claim 1 , characterized in that the protection apparatus ( 18 ) in the transverse direction of the attachment has a width which is adapted to the width of the crop hold-down device ( 14 ).

3 . The attachment according to claim 1 , characterized in that lateral arms ( 23 ) of the first portion of the at least two portions ( 19 ) of the protection apparatus ( 18 ) acts in an articulated manner on the receiver ( 17 ) of the crop hold-down device ( 14 ) via first joints ( 25 ) which define a first pivot axis ( 21 ) or through which the first pivot axis ( 21 ) extends, and in that the lateral arms ( 23 ) of the first portion of the at least two portions ( 19 ) of the protection apparatus ( 18 ) act on lateral arms ( 24 ) of the second portion of the at least two portions ( 20 ) of the protection apparatus via second joints ( 26 ) which define a second pivot axis ( 22 ) or through which the second pivot axis ( 22 ) extends.

4 . The attachment according to claim 1 , characterized in that the lateral arms ( 24 ) of the second portion of the at least two portions ( 20 ) of the protection apparatus ( 18 ) act in an articulated manner on the frame ( 11 ) of the attachment via third joints ( 28 ) which define the third pivot axis ( 27 ) or through which the third pivot axis extends.

5 . The attachment according to claim 1 , characterized in that the attachment can be coupled via the frame ( 11 ) to the agricultural harvesting vehicle.

6 . The attachment according to claim 1 , characterized in that the crop hold-down device ( 14 ) is to be positioned on the collected crops.

7 . The attachment according to claim 1 , characterized in that the protection apparatus is covering the entirety of crop collecting device ( 12 ) and crop conveying device.
