  • Device for visually setting the spring force of a seat suspension for a vehicle
    Patent number: 4612871
    Abstract: A device for visually setting the spring force of a seat suspension for use in an automotive seat according to the weight of an occupant of the seat includes a display section formed of a light reflecting body and disposed on an inside lining of an automotive door for indicating the proper height of the automotive seat, and a visually confirming function section disposed in the seat for enabling the seat occupant to visually confirm the above-mentioned display section when the height of the seat is set at a predetermined level by adjustment of the spring force of the seat suspension. When the spring force of the seat suspension is properly set and thus the height of the seat is set at a predetermined level, the visually confirming function section enables the occupant while remaining seated to visually confirm the display section located in the door lining at a position where the occupant can easily observe it.
