-Ί-

Stackable stacking steel with interchangeable flat padding

Field of application of the invention

The invention relates to a chair which, owing to its stacking and rowing capability, is particularly suitable for the design of cultural facilities such as e.g. Clubhouses, holiday homes is suitable, since with him the occurring in these facilities various seating options can be realized.

Characteristic of the known technical solutions

It is an assembly for the formation of rows of chairs known in each case between two chairs arranged next to each other, formed of a support frame with seats a further equipped with a support frame seat shell is mounted, such that support frame and support frame are each wider than the seat shells and the support frame provided with recesses connecting plates, with which it is supported on the support points of the adjacent chairs (DE-GM 7136 295 / 34g - 1/124).

A disadvantage of this chair design is the material intensity and the high production costs for the production of the support frame on which the seat shell to be hooked is attached. Since the connections to the fixed chair only in the area of the seat - but not in the backrest area - done, the stability of the ranking is not guaranteed. Finally, due to the lack of upholstery and armrests, the chair is not suitable for all sorts of seating arrangements.

Object of the invention

The aim of the invention is to reduce by a simple and expedient design the material and labor for the production of both the fixed and the chairs to be hung, by a corresponding forced locking of the individual elements with each other to achieve sufficient stability of the series network and realize as many seating options to be able to.

Explanation of the essence of the invention

D _e r invention has for its object to provide a chair that by using the same elements - is cheap to produce for the solid as well as for be hooked chair and allows easy stringing, wherein the positive connection of the hinged backrest - as seat and back and seat shell with the fixed chairs forcibly locks the series.

According to the invention this is achieved in that a seat with clamped armrests is clamped on the horizontal parts of the side rails, the side rails clamp-like and are connected by inserted into the undersides of the armrests molded parts made of elastic material with the pipe cross-section. The hinged support area of the armrest is located on the fixed chair with the first and third quarter of the seat depth and is completed by attaching a double-shell backrest on the upper angled parts of the side rails to the fixed chair. In this case, jamming occurs with the concealed back strap and the lower edge of the backrest sits on the horizontally angled parts of the side uprights.

The sequence of the chairs is done in such a way that between each two fixed chairs, which are placed side by side at a distance of the side rails, a 180 ° rotated in the plane seat shell is placed on the side rails of the two chairs, so that the support areas of the Armrests in

the way on the side rails rest, that they embed in the hinged armrests of the fixed chairs and form a continuous armrest and cause a form-fitting series, while by attaching the also rotated by 180 ° backrest on the side rails of the two fixed chairs Row structure in the plane of the backrest is spatially stabilized.

Another feature is that the seat pan and the backrest receive a removable flat padding, which consists of a reference with inserted foam pad, which are clamped by means of hooks between the upper and lower edge of the backrest or front and rear edge of the seat ·

According to another feature, the seat of the fixed chair receives a continuous arm, while the loose seat with also continuous armrest without elastic molding rests on the two outer armrests in the V / iron that by cross-sectional enlargement of the loose armrest to material thickness of the inner cross-section form-fitting manner the outer surface of the armrest of the fixed chair rests.

The generally known frame shown in Fig. 1 to 4 consists of two lateral doubly angled spars 1, which lie in parallel planes, wherein the support for the seat 5 is equal to the armrests and the upper ends of the spars 1 in the inclination of the backrest 6 are issued. The rigid cross-connection is ensured by a straight or curved cross bar 4 in the amount of the seat between the front legs and by the curvature of the backrest б having rear-handle bar 2 with bent ends in the raised upper portion of the spars 1. The externally attached and flared hind legs 3 of the frame at the same time cause the stackability of the chair.

In order to make a chair out of this frame, a seat 5 and a backrest are attached. Fig. 5 to 8 shows the completed chair. The seat 5 has on both sides up to armrest height bent side surfaces which are uragelehnt on the outside at the same angle in such a way that they include the horizontal parts of the side rails 1 like a clamp and form an armrest. The suspension of the seat 5 with the molded armrests is in this case cut out like a hinge, that a rotated in the plane by 180 ° seat 5 causes a positive connection between two seat width apart juxtaposed fixed chairs (Fig. 10 to 12). The associated backrest б is double-shelled and provided on both sides with half the height having rectangular recesses and is attached to the upper ends of the salaried side rails 1, so that also rotated by 180 ° backrest б also on the upper ends of the side rails 1 can be attached by standing next to each other in a distance chairs and thus a durch-

going compound forms the backrest 6 in Reihungsverband.

In the inner sides of the molded armrests of the seat 5 elastic molded rubber parts are inserted, which jam against the tube of the side rails 1. The non-positive bond between the spar 1 and the backrest 6 is caused by the frictional resistance between the laterally protruding ends of the two backrest shells, which are spread by spacers to the dimension of the pipe cross section. Front and back of the backrest б are equal in section, the difference in curvature causes jamming against the horizontal spine 2.

To increase the seating comfort, the chair can be completed by a removable padding δ with washable textlien reference material and incorporated foam plate in such a way that clamping hooks 9 are attached plastic or metal on two opposite hem edges of the fabric cover, the top and bottom edges of the backrest. 6 or include the front and rear edge of the seat 5 and thus brace the padding 8 against the surfaces, with backrest б and seat shell are upholstered in the same width (Fig. 13 to 15) ·

The tension is caused by the deformation of the elastic padding material, which yields when placed by stretching the cover in the clamping direction.

Moreover, it is possible, when using the same frame and the same backrest 6, to change the shape of the seat shell 5 in such a way that, instead of the hinge-like cutouts in the support area, a continuous armrest of the same cross-section is formed. In this embodiment of the fixed chair, the loose seat shell 5 is designed larger in the support area in the inner cross section by material thickness. This results in omitting the elastic molded part of the series composite by overlapping, positive engagement effecting laying (Fig. 16).

The invention provides the basic possibility to procure only the required for a single seating piece fixed stalls, while the required for a row seating extra demand can be covered up to the maximum double seat number of additional seats 5 and backrests 6, with those of the fixed stalls are identical. When retooling the basic seating remains in the hall, while only the magazinierten mold components of the seat shells 5 and backrests 6 must be transported and mounted ·

In addition, the removable padding 8 with the washable textile cover material has the advantage that you can set up the different functional areas cultural facilities with the same basic equipment and thereby differentiate the seating comfort as needed.
