It is best to place a hinge as much as possible in line with each mounted gas spring. The reaction force, coming from the gas spring, can be led through the hinge to any non moving part .
Not placing a hinge in line with the gas spring, calls on the local strength of the cover or the hatch to lead the reaction force, via a transverse movement, still through the hinge to the mounting point. When the cover or the hatch has sufficient stiffness that is not a problem but when the edge of the cover or the hatch has been structured as a frame, this issue demands attention.
In order to prevent uneven loads on the hinges, it is desirable to place the hinges symmetrically to the mounted gas springs.
