In the preferred embodiment of the present utility model, this seat board frame becomes " mouth " font, also forms the installation portion that is used to connect other parts of chair on this seat board frame.

In the preferred embodiment of the present utility model, this middleware comprises many steel wires, and these many steel wires are connected within this seat board frame, and is arranged into " well " font.

In the preferred embodiment of the present utility model, this middleware comprises at least one support bar, and this support bar is fixedly arranged within this seat board frame.

In the preferred embodiment of the present utility model, this support unit also comprises brace, this brace has Fixed Division, pars intermedia and Access Division, this pars intermedia is installed between upper end, Fixed Division and the lower end, Access Division, affixed this seat board frame in this Fixed Division, this Access Division is passed the through hole that is opened in fiberboard and is connected in the fiberboard end face again.

In the preferred embodiment of the present utility model, this pars intermedia is abutted against in the fiberboard bottom surface.

In the preferred embodiment of the present utility model, this seat board cloth cover side is connected between this seat board frame end face and the fiberboard bottom surface.

In the preferred embodiment of the present utility model, this fiberboard is dull and stereotyped.

The beneficial effects of the utility model, owing to be provided with middleware in the seat board frame, the fiberboard support and connection are on this seat board frame and middleware, therefore simple sheet-like fiber plate can satisfy chair seat board requirement of strength, it has overcome the existing deficiency of background technology, and has a following advantage: one, intensity height; Its two, the fiber materials are few, and are simple in structure, processing mold is simple, the yield rate height, required precision is low, whole chair seat board manufacturing cost reduces.Also form installation portion on this seat board frame, make to be connected and installed the intensity height between other parts of chair seat board and chair, convenient.These many steel wires are arranged into " well " font, and the Support Position is suitable, the support strength height.
