Claims

[Claims for Utility Model Registration] (1) Equipped with a side support that has a pair of rotatable support stays on both sides, from an open position where the seated person is away from the upper body, to a closed position where the seated person is supported from both sides. A side support device for a vehicle seat that prevents a seated person from losing his or her sitting posture by rotating a support stay, characterized in that each support stay has a four-bar link structure. (2) Equipped with a side support that has a pair of rotatable support stays on both sides, and the support stays can be rotated from an open position where the seated person is away from the upper body to a closed position where the seated person is supported from both sides. A side support device for a vehicle seat that prevents the sitting posture of a seated person from collapsing, characterized in that each support stay is constructed in a four-bar link structure in which the arm of the driven joint is longer than that of the driving joint. Device.
