Latest Patents

Karl Heinz Ligensa holds a patent for an "Adjusting arrangement" that involves two strap members connectable with a seat member and a backrest member. These strap members are designed for relative pivoting movement. The invention features an inner and an outer gear annulus on the respective strap members that engage with one another. Additionally, a brake sleeve is incorporated on one of the strap members, housing a helical spring that normally frictionally engages its inner surface. The spring is designed with two inwardly angled end portions, allowing for a turnably mounted output member within the sleeve. This output member has a section extending between the end portions of the spring, while a turnable control member is adjacent to it, also extending between the end portions. A torsion spring engages both the input and control members, ensuring they remain in contact with the respective end portions of the helical spring. This innovative design enhances the adjustability and comfort of seating arrangements.
