Seat with suspension unit for automotive vehicle
First Claim
1. A suspension seat for an automotive vehicle comprising:
- a seat frame;
a parallel link mechanism supporting said seat frame to be vertically movable above a vehicular floor, said parallel link mechanism including front and rear links;
a suspension unit connected to an upper bracket integral with said seat frame and to the rear link, said suspension unit including a compression spring and a shock absorber which are coaxially arranged so as to extend in a generally vertical direction; and
a bearing made of resilient material rotatably supporting the rear link on the vehicular floor, said bearing having an outwardly and upwardly projecting portion which directly receives a part of the seat frame when the suspension seat is downwardly moved due to an impact force applied thereto.

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.
