Patent GB-2034851-A (GB)
Title: Force transmission mechanism
IPC: B60N2/50
Filed: 1978-11-09
Abstract: A force-transmission mechanism in which a band 15 of material extending from a self-coiling spring 16 of said band material is wound in a coil 14 on a shaft 13 so that rotation of the shaft in opposite directions draws band material from the supply coil or pays it back into the supply coil thereby increasing or decreasing the diameter of the coil on the shaft. A rotor 18b is biassed into contact with the shaft coil 14 so that rotation of the shaft in a sense to increase the diameter of the shaft coil drives the rotor away from the shaft. This mechanism is suitable for use in a vehicle seat in which rotation of a manually operable knob fixed to the shaft can vary the torque in a seat- supporting torsion spring having a radial arm carrying the rotor at its outer end. <IMAGE>
