POWER SEAT SLIDING DEVICE AND VEHICLE SEAT
First Claim
1. :
- A power seat sliding device comprising;
a pair of left and right sliders disposed at a predetermined distance, and including upper rails being movably disposed on lower rails and supporting a seat;
a pair of left and right slide screws disposed along moving directions of the upper rails;
nut members screwed to the slide screws; and
a driving force transmission mechanism configured to cause one connected to the upper rails, of the slide screws and the nut members to rotate relative to the other connected to the lower rails, the driving force transmission mechanism including;
a pair of left and right gear mechanisms disposed on the upper rails or the lower rails and configured to transmit a rotation force that causes the slide screws and the nut members to rotate relatively;
a drive unit disposed between the pair of left and right gear mechanisms and consisting of a motor that generates a rotation force; and
a rotating mechanism disposed between the drive unit and one of the pair of left and right gear mechanisms so as to be connected to an output shaft of the drive unit, the rotating mechanism having a function of compensating for an energy loss of a rotation force of the drive unit.

Abstract
To reduce energy loss to increase power transmission efficiency, as well as to suppress unusual sound resulting from whirling vibration. A driving force transmission mechanism includes a drive unit that generates a rotation force and consists of a motor, as well as an independent rotating mechanism that is disposed between the drive unit and one of a pair of left and right gear mechanisms so as to be connected to the output shaft of the drive unit and has greater kinetic energy than the rotating parts of the gear mechanisms. Flexible shafts that rotate by smaller kinetic energy than any of the kinetic energy of the drive unit, the kinetic energy of the rotating mechanism, and the friction forces and damping forces of the rotating parts of the gear mechanisms connect between the drive unit and rotating mechanism, between the rotating mechanism and one gear mechanism, and between the drive unit and the other gear mechanism.
