Abstract
The invention is a profiled bar, in particular sprung bars, in which a reinforcement of both synthetic fibers and natural fibers is embedded in a plastic matrix. The proportion of synthetic fibers can be reduced by using natural fibers derived from regrowing raw materials. This improves environmental compatibility and makes it easier to dispose of such sprung bars. The sprung bars are used in particular to form bottom sprung supports for furniture for sitting and lying on, and in particular for slatted frames.
Claims14
A load bearing, prism-shaped profiled bar, having a plastic matrix and fibres arranged therein, characterized in that the fibres are synthetic fibres and natural fibres, wherein, the synthetic fibres are assigned to selected cross-sectional areas, the natural fibres are assigned to cross-sectional areas that are left free by the synthetic fibres, the synthetic fibres are assigned to different cross-sectional areas from the natural fibres, and the synthetic fibres and the natural fibres are completely embedded in the plastic matrix.
A load bearing, prism-shaped profiled bar, having natural fibres and synthetic fibres arranged in a plastic matrix, characterized in that:
- a. the synthetic fibres are assigned to selected outer cross-sectional areas of the profiled bar;
- b. the natural fibres are assigned to other selected cross-sectional areas of the profiled bar, different from the selected cross-sectional areas in which the synthetic fibres are assigned and free of the synthetic fibres;
- and
- c. the synthetic fibres and the natural fibres are completely embedded in the plastic matrix.
