Publication number: 20040124061Abstract: A braking drive for a control cable or shaft has a drive shaft with a radial journal. A contractible brake ring has opposing ends defining a gap, with the journal in the gap The ring has an exterior surface biased outwards and two interior detents. A stationary interior housing circumscribes the ring, with an interior surface in frictional contact with the ring. An exterior portion of the housing has bosses being disposed within the detents of the ring. Friction between the ring and the housing interior arrests rotation of the journal and drive shaft until a force on the exterior portion of the housing moves the bosses, transferring the force to the ring via the detents, whereby the ring is contracted, releasing the frictional brake between the housing and the ring, thereby allowing rotation of the drive shaft.Type: ApplicationFiled: October 13, 2003Publication date: July 1, 2004Applicant: Schukra Geratebau AGInventor: Wilhelm Schuster

Publication number: 20010042670Abstract: A brake drive is described which is characterized in that at least one brake drum (1) largely secured against rotation has in its interior at least one expanding ring (2) which is larger in diameter prior to installation, which after installation has a first inherent expansion friction against rotation owing to its expansion force at all points of the friction faces (5), which inherent expansion friction undergoes an additional expansion and braking intensification up to potential total blocking in the event of a reverse torque on the driven shaft (3) via the driving journal (4) thereof and the driving journal's circular thrust on one of the two end faces of the expanding ring (2) which total blocking contracts the expanding ring owing rotation of the primary hand wheel (6) or primary contracting pivoted lever (6a) at the input side with the aid of the two contracting journals (6′ and 6″) securely attached thereto, again owing to a circular tensile force on the opposing end face of the expanding rType: ApplicationFiled: March 9, 2001Publication date: November 22, 2001Inventor: Wilhelm Schuster

Patent number: 6079783Abstract: A back rest for a seat wherein the back rest includes a support member having first and second edge surfaces, a central plate between the edge surfaces, a first side member coupling the central plate to the first edge surface, and a second side member coupling the central plate to the second edge surface. The central plate of the support member is recessed from the first and second end surfaces to define a cavity. The back rest further includes a plurality of protrusions extending from the central plate and into the cavity. Additionally, the back rest includes a lordosis support having first and second ends coupled to the plurality of protrusions, at least one of the first and second lordosis support ends being coupled to the plurality of protrusions for movement relative to the support member. The lordosis support is adapted to bow upon displacement of one of the first end and the second end thereof toward one another thereby forming a curvature.Type: GrantFiled: October 17, 1996Date of Patent: June 27, 2000Assignee: Wilhelm Schuster, SeniorInventors: Wilhelm Schuster, Sr., Knud Klingler
