Claims

[Scope of utility model registration request]

Of the two links that intersect with each other and are rotatably connected to each other at the intersection, the lower end of one link is attached to a point on the fixed part, and the upper end of the other link is attached to a seat. The lower end of the other link is slidable on a line passing through the point where the lower end of the one link is fixed, and In a vehicle seat adjustment device, a plurality of sets of parallel movement mechanisms are provided in parallel, each of which has an upper end of the link slidably slidable on the lower surface of the seat metal fitting parallel to the sliding line of the lower end of the other link. , a rectangular cylindrical member whose lower end has an axis perpendicular to the rotating surface of the link and is rotatable; and a corner provided through the rectangular cylindrical member. The square tubular member and the square shaft member are fixed to one of the shaft members, and one of the square tubular member and the square shaft member is rotatably fixed to one point of the fixed part, and the square tubular member and the square shaft member are fixed to one of the shaft members. constitutes a torsion rubber spring mechanism that supports torsional loads via an elastic body provided therebetween, and among the square tubular member and square shaft member,
The member to which the link is not fixed is provided with a strength adjustment device that increases or decreases the torsional load and adjusts the seat height, and the member to which the link is fixed is provided with a strength adjustment device that prevents the member from rotating. 1. A vehicle seat adjustment device, characterized in that the vehicle seat adjustment device is provided with a rotation prevention device.
