Abstract
The invention concerns a device for transmitting a rotational movement comprising a flexible shaft and a sheath inside which the flexible shaft is housed, said sheath being arranged in order to allow the rotation of said shaft inside said sheath. The outer surface of the flexible shaft is machined so as to have a substantially smooth surface finish. The invention also concerns an adjustment system for a motor vehicle seat comprising such a device.
Claims19
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 to said runner, said system also comprising a drive motor having at least one revolving output, 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, wherein the transmission device comprises a cable including helically wound wires, an outer surface of each of the wires being substantially flat after machining.
A seat assembly comprising:
- an adjustable seat;
- an electromagnetic actuator;
- and
- a cable operably moved by the actuator to move the seat, the cable comprising a flexible shaft and a sheath inside which the shaft operably rotates, the shaft comprising a cable including a winding of metal wires wherein an outer surface of each of the wires is substantially flat after machining, the shaft having a substantially smooth finish.
A seat apparatus comprising:
- an adjustable seat;
- an automatic actuator;
- and
- a cable operably rotated by the actuator to move the seat, the cable having a plurality of helically wound wires wherein an outer surface of the cable is substantially flat after machining.
