Description

TECHNICAL TERRITORY

The The present invention relates to a neck support for a chair with backrest, which neck support in cross-section approximately U-shaped, provided with a padding and on the upper edge of the backrest is pluggable. The invention also relates to a chair with a Such, attachable to the upper edge of the backrest neck support.

Out DE 100 58 503 A1 and DE 19 21 366 U each neck supports of the type mentioned are known.

From DE 100 58 503 A1 Known neck support has a over the front of the backrest downwardly projecting, padded support and on the back of the backrest downwardly extending rear wall. Pad and back wall exert a clamping action on the backrest when the neck rest is placed on the backrest.

The neck support according to DE 19 21 366 U has a one-piece, resilient clamping device made of plastic, which also exerts a clamping effect on the backrest.

PRESENTATION THE INVENTION

task The present invention is a neck support of this kind for a Chair with backrest and specify a chair with such a neck support, wherein the neck support in particular simple and efficient to produce and therefore inexpensive should.

These Task is solved by the features specified in claim 1 or 6 features. advantageous Embodiments of the neck support are in the subclaims 2 to 5 indicated.

According to claim 1 includes the neck support two dimensionally stable, essentially forming the legs of the U-shape, out of this into an open position pivotally interconnected, largely dimensionally stable shells, which respect the U-shape provided on the outside with a continuous padding are.

By the two largely dimensionally stable, mutually pivotable shells Already the upholstery can be installed very rationally by: e.g. the outside Poster cloth (or the outer Upholstery leather) after attaching a soft cushion pad on the Outer sides of the two shells pulled from outside over this and stretched and then inside (with respect to the u-shape) on the shells is attached. This attachment can be with usual Agents such as e.g. Antipersonals also run very easily, though while the two shells pivoted into their open position are. The two bowls also guarantee that the upholstery and the neck support overall "in shape" remains, even if she over a longer period is heavily loaded.

The both bowls can with advantage injection molded plastic parts.

at a spitzgusstechnischen production, the two shells can even be manufactured in a single operation as a one-piece part, wherein the connection between them, the one against each other allowed to be realized in the form of at least one film hinge can.

to Attachment of the inventive neck support the upper edge of the backrest she can at her as the back provided leg with at least one keyhole-shaped Einhängeöffnung and at the other Leg with at least one push button or a corresponding Druckknopföse be provided with a push button connection, wherein in this embodiment of the pivoting of the two shells against each other in part also is used again. In this training, the neck support to Fastening on the upper edge of the backrest namely first with its at least one, keyhole-shaped suspension opening at least one suitably placed on one side of the backrest and from this protruding mount button hooked and then secured by gently pulling up on the Einhängeknopf. After that will she over the upper edge of the backrest folded into their u-shape and finally by pressing the at least one push-button connection on the opposite Side of the backrest, but easily detachable here, fixed.

By doing the suspension connection on the back of the backrest is arranged, releases they do not turn off when e.g. the entire chair once from the back on the neck support should be recorded and thus moved.

According to claim 6, the chair with Backrest with a fastened on the upper edge of the backrest neck support provided with the features according to claim 5. Thereafter, the neck support comprises two dimensionally stable, substantially the legs of the U-forming forming, out of this in an open position pivotally interconnected, largely dimensionally stable shells, which are provided with respect to the U-shape on the outside with a continuous padding. At its leg provided as the rear side, the neck support has at least one keyhole-shaped suspension opening and at its other leg at least one push-button or a corresponding push-button lug of a push-button connection. The backrest of the chair has within a padding on a made of a foamed plastic material plate-shaped stiffener. At this stiffener is at some distance from the upper edge of the back at least one thickness of the padding there bridging first mounting dome for a Einhängeknopf and front side at least one thickness of the padding there also bridging second Befestigungsdom formed for a push button or a corresponding snap fastener.

By This training, the neck support in a simple way so on the backrest be secured so that they are secured against unintentional removal is, but still take off with a few simple steps leaves.

SHORT EXPLANATION THE FIGURES

The Invention is intended below with reference to embodiments in connection closer to the drawing explained become. Show it:

1 in view from behind a neck support according to the invention placed on the backrest of a chair with two inner, made visible by hidden lines subshells;

2 a cut through DD 1 ;

3 the partial shells in unfolded position;

4 the partial shells in folded position; and

5 the backrest with the attached neck support in an overall view.

WAYS TO PERFORM THE INVENTION

In the 1 . 2 and 5 designated 1 with a plate-shaped stiffener 2 as well as a padding 3 provided backrest of a chair and 4 a patch on the upper edge, in cross-section approximately U-shaped neck support.

The neck support 4 includes according to 1 and 2 two inner, essentially the legs of the u-shape forming shells 5 and 6 , which on the outside also with a padding 7 are provided. The shell 5 is on the back and the shell 6 on the front of the backrest 1 arranged.

The two bowls 5 . 6 are manufactured as a largely dimensionally stable plastic injection molded parts together and in one piece and over two pointed technically the same with trained film hinges 8th pivotally connected to each other.

3 shows the two bowls 5 . 6 in unfolded and 4 in folded position.

The padding consisting of a foam blanket and a cover 7 the neck support 4 gets through the two shells 5 . 6 kept in shape. The cover is pulled from the outside to the inside over their outer edges and stretched and secured to them on the inside by Antacker.

The neck support 4 is on the backrest 1 additionally attached. At her back shell 5 are on the one hand two keyhole-shaped suspension openings 9 formed, which in hanging buttons 10 mounted on the back of the back and can be secured by moving against hanging. On the other hand are on the front shell 6 two snap-on eyelets 11 provided, which with two snaps 12 interact on the back of the backrest. The push buttons 12 are arranged at such a height that the push-button connection 11 . 12 can only be closed when the rear suspension connections 9 . 10 in their secure position against being posted. The neck support can be attached in this way 4 can be easily removed at will from the backrest. When attaching as when removing as well as closing or releasing the push-button connection their Aufklappbarkeit from the u-shape of additional advantage.

Like this in 2 is recognizable, are the hanging buttons 10 in attachment domes 13 fixed, which on the back of the plate-shaped stiffener 2 the backrest 1 are molded and also the padding 3 to bridge the backrest. The push buttons 12 are in corresponding, front on the plate-shaped stiffener 2 the backrest 1 molded fastening domes 14 fixed, which there also the padding 3 the backrest 1 bridged.

The plate-shaped stiffener 2 the backrest 1 For example, it may be made from a plastic material foamed in a mold. The dome of the fortification 13 . 14 can be molded with no additional effort by appropriate training of the form with.

5 shows an overall view of the backrest 1 with attached neck support 4 how she visually presents herself from the front.
