Seat with suspension unit for automotive vehicle

Abstract

A suspension seat for an automotive vehicle has a seat frame which is vertically movably supported on a parallel link mechanism. A compression spring and a shock absorber of a suspension unit are coaxially assembled. A spring bracket is disposed on the compression spring and screwed with a rod of the shock absorber. A fixing nut is fixed to the rod on the spring bracket to adjust elastic force of the compression spring by changing the position of the spring bracket. A projection of the spring bracket projects from a slit of a suspension unit support bracket with scale division. A resilient bracket supports the parallel link mechanism and outwardly projects to function as a bumper for a seat frame. Therefore, the suspension seat suppresses shock or sound due to impact during an operation of the seat and realizes a simple adjustment of hardness of the suspension unit.
