Claims

[Scope of utility model registration request]

A suspension seat device for an automobile in which a suspension device is interposed between a vehicle body part and a seat. and a bell crank, which is connected to the spring member through a connecting point and converts the spring force in the axial direction of the spring member into a spring force in the seat load direction. The lever ratio of the bell crank can be changed by moving the connection point on the lever part, so that the suspension can be adjusted.
A spring constant variable device that changes the spring constant in the seat load direction of the spring constant variable device is provided, and the direction in which the above connection point of the spring constant variable device is moved can be changed by changing the lever ratio of the bell crank. A suspension seat device for an automobile, characterized in that a spring member is set in a direction that expands and contracts so as to prevent a change in force.
