a connecting member that is spaced apart from the mounting base carrier; and
a plurality of lateral attachments which are connected to the mounting base carrier and the connecting member;
wherein the plurality of lateral attachments, the mounting base carrier, and the connecting member form a device body with a height direction;
wherein the connecting member is spaced apart from the mounting base carrier in the height direction of the device body;
wherein each lateral attachment of the plurality of lateral attachments forms a main lashing point for attachment of human external cargo and comprises an associated inner web that is connected to the mounting base carrier and the connecting member; and
wherein the associated inner webs of the plurality of lateral attachments are spaced apart from each other in peripheral direction of the mounting base carrier and form a tube-shaped inner region extending in height direction of the device body.
2 . The human and/or non-human cargo attachment device of claim 1 , wherein each lateral attachment of the plurality of lateral attachments extends in an associated extension plane, and wherein the associated extension planes of the plurality of lateral attachments are spaced apart from each other in the peripheral direction of the mounting base carrier.
3 . The human and/or non-human cargo attachment device of claim 2 , wherein each lateral attachment of the plurality of lateral attachments comprises an upper web and a lower web which are interconnected in an angled arrangement at an associated interconnection region and which are further connected to the associated inner web of the lateral attachment.
4 . The human and/or non-human cargo attachment device of claim 3 , wherein the upper web, the lower web, and the associated inner web of each lateral attachment of the plurality of lateral attachments form a triangular structure in the associated extension plane of the lateral attachment.
5 . The human and/or non-human cargo attachment device of claim 3 , wherein the main lashing point of each lateral attachment of the plurality of lateral attachments is arranged in the associated interconnection region of the lateral attachment.
6 . The human and/or non-human cargo attachment device of claim 3 , wherein each lateral attachment of the plurality of lateral attachments forms a redundant lashing point for an additional attachment of the human external cargo.
7 . The human and/or non-human cargo attachment device of claim 6 , wherein the redundant lashing point of the lateral attachment is arranged in the associated interconnection region of the lateral attachment.
8 . The human and/or non-human cargo attachment device of claim 1 , wherein the mounting base carrier is further removably attachable inside the tube-shaped inner region to an additional attachment for attachment of non-human external cargo.
9 . The human and/or non-human cargo attachment device of claim 8 , wherein the mounting base carrier is at least equipped with two mounting lugs which are attachable by means of a mounting bolt to the additional attachment.
10 . The human and/or non-human cargo attachment device of claim 1 , wherein the mounting base carrier is plate-shaped, wherein the associated inner webs are connected to an outer circumference of the mounting base carrier, and wherein the mounting base carrier and the plurality of lateral attachments form a star-shaped arrangement in radial direction of the mounting base carrier.
11 . The human and/or non-human cargo attachment device of claim 1 , wherein the plurality of lateral attachments is further interconnected via associated stiffening ribs.
12 . The human and/or non-human cargo attachment device of claim 1 , wherein the mounting base carrier is at least equipped with three mounting lugs which are attachable by means of a mounting bolt to an associated attachment for attachment to a rotorcraft rope or cable.
13 . The human and/or non-human cargo attachment device of claim 1 , wherein the device body is 3D printed, preferably by means of a 3D titanium printing process.
14 . The human and/or non-human cargo attachment device of claim 1 , wherein the device body forms a confined space outside the tube-shaped inner region, and wherein the confined space is filled with foam.
15 . The human and/or non-human cargo attachment device of claim 1 , wherein a plurality of redundancy cables or ropes is routed inside the device body to guarantee secure functioning of the device body at least upon breakage of one or more of the plurality of lateral attachments.
