Claims

[Scope of Utility Model Registration Claim] In a vehicle seat that can change its direction greatly for getting on and off, a rotating base that supports the seat is attached to a support base that is installed on the floor via a seat slide, and a rotating base that supports the seat is attached to the rear side end. an upper rail member to which the rotating base is fixed and a support base are fixed to the vicinity of the pivot shaft and to a front portion spaced apart from the pivot shaft. The seat is supported by a rotary support unit comprising an arc-shaped guide rail unit which is slidably fitted to the lower rail member and cannot be separated from the upper and lower sides thereof, and which is arranged concentrically in parallel with the pivot axis; A drive part is mounted on the upper rail member of the guide rail unit of the section, a pinion is fixed to the output shaft of the drive part, and an arc-shaped rack with which the pinion engages is provided on the side wall of the lower rail member. A vehicle seat characterized by being provided with a mechanical part.
