Problems solved by technology

[0006] However, in the vehicle seat device of Patent Document 1, since the drive mechanism and the rotating link (62) are arranged on the front link (22) for the lifter, the front link (22) for the lifter becomes huge, and Larger peripheral space is required to rotate the rotary link (62)
Furthermore, for the rotary link (62), since the range of inclination adjustment is proportional to the length between the center of rotation of the rotary link and the connecting portion of the rotary link with respect to the swing link (64), therefore , in order to increase the adjustment range of tilt adjustment, it is necessary to increase the rotation link (62), so it is difficult to obtain sufficient rigidity
And, the front end portion of the lower arm (26) is rotatably connected to the front link (22) for the li

Abstract

A vehicle seat device having a mechanism for adjusting the tilt of a seat cushion, having high rigidity, having a small size, and having a good appearance. [MEANS FOR SOLVING PROBLEMS] The vehicle seat device has a rotation link (20); a front bracket (40) for installation on a floor surface and a front rocking link (71), the front bracket (40) and the front rocking link (71) interconnecting a first joint (22) of the rotation link (20) and an upper rail (82); a side bracket (10) where the rotation link (20) is fixed to a front section (21); a rear bracket (50) for installation on the floor surface and a rear rocking link (73), the rear bracket (50) and the rear rocking link (73) interconnecting a rear section (11) of the rotation link (20) and the upper rail (82); front drive devices (60-62) fixed to the side bracket (10) and rotationally driving the rotation link (20); and a cushion frame (30) having a rear section (32) and a front section (31) to which, respectively, the side bracket (10) and a second joint (23) are connected. A cushion frame rocking link (72) interconnects the second joint (23) and the cushion frame (30).

Description

technical field [0001] The present invention relates to a vehicle seat device capable of tilting and adjusting a front portion of a seat cushion having a seat surface facing a user's buttocks up and down. Background technique [0002] As a conventional vehicle seat device, Patent Document 1 discloses a vehicle seat device provided with a rotary link (62) and a swing link (64), the rotary link (62) is rotatably engaged with the lifter front link (22), and one end of the swing link (64) is relatively rotatably connected to the rotation link (62), and the seat cushion is pivotally mounted. At the other end of the swing link (64), the tilt of the seat cushion is adjusted by rotating the rotation link (62) by a drive device mounted on the front link (22) for a lifter. [0003] Furthermore, Patent Document 2 discloses a vehicle seat device in which a drive mechanism (251) of a front vertical (front vertical) mechanism (201) and a drive mechanism (351) of a rear vertical (rear ver...
