Abstract
The invention concerns a rotational movement transmission device comprising a flexible shaft and a casing inside which the shaft is housed, said casing being formed from a hollow body of plastic material whose internal diameter is arranged to allow the rotation of said shaft inside said casing, the wall of the body having a variable thickness so that at least part of the casing has an internal surface comprising corrugations extending longitudinally. The invention also concerns an adjustment system for a motor vehicle seat comprising such a transmission device.

A rotational movement transmission device comprising a flexible shaft and a casing inside which the shaft is housed, said casing being formed from a hollow body of plastic material whose internal diameter is arranged to allow the rotation of said shaft inside said casing, the wall of the body having a variable thickness so that at least part of the casing has an internal surface comprising corrugations extending longitudinally.
An adjustment system for a motor vehicle seat, comprising at least one adjustment runner mounted on the structure of the vehicle and adjustable means for fixing the seat on said runner, said system also comprising a drive motor having at least one revolving part, and a transmission device disposed between the output of said drive motor and said fixing means, so as to move said fixing means along said adjustment runner in response to a rotation of said output.
A motor vehicle seat adjustment system comprising:
- at least one adjustment runner;
- an actuator having at least one revolving part;
- and
- a transmission causing movement along said adjustment runner in response to operation of said actuator, said transmission including a rotating shaft inside a casing, said casing having permanent deformations arranged to limit vibrations without reducing an internal diameter of said casing.
