POWER SEAT SLIDE DEVICE AND VEHICLE SEAT
First Claim
1. A power seat slide device which adjusts a pair of sliders arranged at a predetermined interval by a driving force of a motor to adjust a position of a seat cushion in a front-rear direction in a vehicle seat,the pair of sliders each comprising:
- a lower rail fixed to a floor of the vehicle seat, with a longitudinal direction of the lower rail being along the front-rear direction of the seat cushion;
an upper rail disposed to be movable along the longitudinal direction of the lower rail and supporting a cushion frame of the seat cushion; and
a lock mechanism which locks the upper rail to the lower rail at an appropriate slide position, the device further comprising;
a rack disposed along the longitudinal direction of the lower rail; and
a pinion which is supported on the upper rail or the cushion frame, is meshed with the rack, and rotates by the driving force of the motor being transmitted thereto,wherein, while the motor is energized, the motor is actuated in conjunction with a release operation of the lock mechanisms to rotate the pinion to cause front-rear movement of the upper rails along the lower rails, andwherein, while the motor is not energized, the front-rear movement of the upper rails along the lower rails is enabled by manual adjustment.

Abstract
A power seat slide device capable of changing not only to an electric operation but also to an manual operation, and preventing half-lock in spite of a manually operable structure. For front-rear movement, a rack attached to a lower rail and a pinion meshed with the rack are used, and a driving force of a motor is transmitted to the pinion, which enables the use in an electric mode. As no slide screw is used, while the motor is not energized, rotating the pinion causes an output shaft of the motor to rotate, so that manual adjustment becomes possible.
