Claims

[Claims for Utility Model Registration] 1. A cushion frame, a spring tensioned on a spring holding member provided inside the cushion frame,
and a cushion material placed on the spring, the cushion pressure adjustment mechanism presses the cushion material from the lower surface by the spring and adjusts the cushion pressure by varying the pressing force, the cushion pressure adjustment mechanism comprising: A tapered block moving body having screw holes arranged on both sides of the cushion frame, a spring holding member holding the spring and placed on the tapered surface of the tapered block moving body, and a rotatable spring holding member on both sides of the cushion frame. An operating shaft is supported by the operating shaft and has a threaded portion at a predetermined position, and the screw hole of the taper block moving body is screwed into the threaded portion of the operating shaft, and when the operating shaft is rotated, the tapered block moving body moves forward and backward. A cushion pressure adjustment mechanism for a seat, characterized in that a spring holding member that moves and holds the spring moves upward and downward. 2. The lever operation shafts provided on both sides of the cushion frame are such that when one of them is rotated, the rotation is transmitted to the other operation shaft via the screw shaft and the operation shafts are interlocked with each other. Seat cushion pressure adjustment mechanism as described.
