  • Publication number: 20240170690
    Abstract: A separator plate for an electrochemical system and a bipolar plate comprising two such separator plates for an electrochemical system. An electrochemical system comprising at least two separator plates and/or one bipolar plate. A separator plate comprising: at least one sealing bead for sealing off a region of the separator plate and at least one load relief bead which relieves load on the sealing bead, the load relief bead arranged spaced apart from the sealing bead, and, in a cross-section perpendicular to the course of the load relief bead, at least in a non-compressed state of the separator plate, at least one bead flank of the load relief bead comprises, in at least a first segment along the direction of extension, at least a first, outer portion and a second, inner portion which are at different positive angles to the separator plate plane.

  • Patent number: 4474406
    Abstract: The present invention relates to a vehicle seat, particularly for airplanes and buses. The seat has a support with an adjacent divider having a bore therethrough. A hollow pin has an end section detachably engaged in the bore of the adjacent seat divider. A back rest is mounted at one of its sides on the hollow pin. A connecting body is arranged in the bore of the seat divider and has a longitudinally threaded bore therethrough. A threaded bolt passes through the hollow pin and engages with the threaded bore through the connecting body. A folding table support is mounted on the threaded bolt for pivoting movement thereabout. A stop projects from the hollow pin and limits the pivot movement of the folding table support.
