Rotary vehicle seat facilitating boarding and deboarding

Abstract

A rotary car seat facilitating getting in/out of a car includes: a frame portion constituting a framework of a seat and supporting a load; and a sheath portion formed outside the frame portion. The frame portion includes a backrest frame constituting a framework of a backrest seat and supporting a load, and a cushion frame constituting a framework of a cushion seat and supporting a load. The cushion frame includes an upper frame plate on which the sheath portion is seated, a lower frame plate formed beneath the upper frame plate, a link portion connecting the upper frame plate to be able to rotate on the lower frame plate, and a position setting mechanism is configured to set an area of rotation of the upper frame plate. The lower frame plate is connected to the backrest frame, and the upper frame plate is not connected to the backrest frame such that the upper frame plate can solely rotate independently. The upper frame plate includes a roller portion having a wheel. The lower frame plate includes a guide groove formed to be recessed inward from the lower frame plate along a trajectory of movement of the roller portion that is supposed to move when the upper frame plate rotates around the rotating shaft, so as to guide movement of the roller portion.
