  • Breathable residual-limb socket system
    Patent number: 11938045
    Abstract: Breathable residual-limb system that admits air and allows sweat to evaporate from the surface of the residual limb. In an embodiment, the system comprises a liner sock to be worn on the residual limb, and comprising air-permeable textile forming a substantially cylindrical portion that is closed on a distal end and open on a proximal end and comprising an internal surface and an external surface. The liner sock further comprises a friction-interface material that covers only a portion of the internal surface of the air-permeable textile, such that, when worn on the residual limb, the friction-interface material contacts a surface of the residual limb, and an uncovered portion of the air-permeable textile which the friction-interface material does not cover allows air to pass between an external environment of the liner sock and the surface of the residual limb.

  • Motor vehicle door entry area
    Patent number: 5902007
    Abstract: Door entry area for a motor vehicle has a cover for a cable duct and a door entry rail joined by metal clamps with a sill flange lengthwise member. The cover for the cable duct has a strip-shaped projection that overlaps the sill flange by force and in a sealing fashion, and the door entry rail is designed as a T-section that has a central retaining member and two shaped legs that project approximately horizontally in the assembled state, with the retaining rib being lockable by means of a latching connection accessible for disassembly in a receiving groove of the cover that abuts the projection and runs along the sill flange.
