Claims

[Scope of utility model registration request]

In a power seat device that has front and rear vertical mechanisms that move the seat cushion up and down and a mechanism that slides the seat cushion in the front and back direction, the center of the support bracket is fixed to the front of a pair of upper rails that are arranged parallel to each other in the front and back direction. A slide motor is arranged in the section, a reduction gear is connected to the rotating shaft of each slide motor immediately inside a pair of upper rails, and a pair of slides are attached to the upper rails connected to this reduction gear and extend in the front-rear direction. A screw shaft and a nut screwed to the screw shaft and fixed to the lower rail are arranged, and a front vertical motor and a rear vertical motor supported by the upper rail are arranged behind the slide motor, and each motor is decelerated. Screws are connected to each other through a device, and nuts are screwed to each of the screws, and the front and rear vertical connecting rods, which are rotated by the nuts that move relative to each other as the screws rotate, are connected to the seat cushion. The front vertical connecting rod is provided with links at both ends that move the front part of the seat cushion up and down, and the rear vertical connecting rods are each provided with links placed between the upper rail and the slide screw. A power seat device characterized in that this link and an L-shaped link that moves the rear part of the seat cushion up and down are connected by a connecting link.
