Chair seat made of bars and bars

Utility model

Me firing · concerns a chair seat made up of mutually parallel Rungs and arranged transversely to these and parallel to each other Bars, which form a cohesive, unitary piece of plastic and in cross-section perpendicular to their Longitudinal extension are ΈΓ-shaped. The chair seat according to the innovation is characterized by the fact that a bar at its intersection with one of the two outer rungs a stiffening web extending in the direction of the longitudinal extension of the rungs between has its two IT legs ·.

One advantage of the chair seat according to the invention is that it is in the area the parts of the intersection of the one outer rung with the two outer strips have an increased strength. These crossing points are when the chair seat lies on a chair frame Exposed to stresses, which compared to the stresses the rest of the stool sites are large. Me contact surface with which the chair seat is on the chair frame, is at the crossing points,

—2—

i.e. the two corners of the chair seat far from the backrest of the chair, enlarged. The chair seat is therefore and because the width its strips are unusually large, for chair frames with! e.g. usable for folding brewery chairs where the width of the support struts is relatively small and the distance between the Support struts fluctuate from one another «The end of the Treg struts in front of the outer edge of the outer rung, because this end of the ! Drag braces then rests on the support edge of the stiffening web.

In the drawing, the chair seat according to the invention is in a preferred one Embodiment shown. It shows

3? Ig 1 a view of the chair seat from below, Big. 2 the section II-II of FIGS. 1 and ! ig. 5 the section III-III of fig, 1.

The chair seat shown consists of six rungs 1, which one Form the seat, and two strips 2, which connect the rungs, and is a one-piece plastic piece from a somewhat resilient elastic plastic. The rungs 1 and 2 run each parallel to each other and at a distance from each other. The rungs 1 and the strips 2 run at right angles to one another. The rungs 1 and the strips 2 are U-shaped in cross section at right angles to their longitudinal extension. The legs 3 of the rungs 1 run at the crossing points through the strips 2. The handles 4

the strips 2 run through the rungs 1 at the crossing points through.

The rungs 1 are slightly part-circular in the direction of their longitudinal extension knitted. The run in the area of the crossing points free ends of the legs 3 of the rungs 1 but horizontally and form support edges 5 »which on! Drag braces β one not closer shown chair frame of a folding brewery chair. The Iragstreben β end in front of the outer leg 3 of the outer rung 1. ■. "-.

One of the two outer rungs 1 has at the two crossing points with the two strips 2 each have a stiffening web 7. Each stiffening web 7 runs between the two legs 4 one of the two strips 2 and connects these two vision- » kel. It extends in the direction of the longitudinal extension of the outer one Rung 1 and has an additional support edge at its free end 8, which rests on the! Eragstrebe 6. The stiffening bar 7 has from the two strings 3 of the outer rung 1 distance and a thickness which corresponds to the thickness of the legs 3, 4 of the rungs 1 or Bar 2 is at least approximately the same. The width of the rungs 1, which extends in the direction of the longitudinal extension of the strips 2, is less than the width of the strips 2, which look towards the longitudinal extension of the rungs extends. The width of the bars is greater than twice the width of the support struts 6.
