SPACESUIT SHOULDER HINGE Russian patent published in 1997 - IPC

FIELD: aeronautical engineering and space engineering; spacesuits. SUBSTANCE: longitudinal load-bearing system of shoulder hinge of spacesuit includes ears 4; it is connected with two axles 6 of rotation by means of link 5. Transverse load-bearing member 10 is made in form of lens-shaped wire skeleton covered with fabric; ends of skeletons are movably secured on axles of rotation of links 5. Hinge portion of envelope 2 is made in form of sphere and smooth portion is made in form of cone in under-arm area. Diameter of transverse load-bearing members nearest to bearing 1 is lesser than its inner diameter and diameters of subsequent transverse load-bearing members exceed those of previous ones but are lesser than inner diameter of bearing by amount of at least double thickness of envelope. EFFECT: enhanced reliability. 2 cl, 9 dwg
