EP1652453B1 - Chair with backrest - Google Patents

Abstract

The support has two dimensionally stable shells (5, 6) that are rotatably connected with one another in an open position by a film hinge. The shells are provided with an integrated upholstery (7) with respect to the U-shape of the support. The two shells are injection moulded from plastic and are formed as a one piece part. A plate-like reinforcement manufactured from plastic material is provided in an inner side of the upholstery. An independent claim is also included for a chair with a backrest in which a neck support is attached.

Description

TECHNICAL AREA

The present invention relates to a chair with backrest according to the preamble of claim 1.

STATE OF THE ART

Chairs with backrest, which have a pad-shaped stiffener made of a foamed plastic material within a padding known and basically executable in a variety of forms. Also known neck supports for chairs with backrest.

US 2003/0137176 discloses a headrest for a chair with backrest, which headrest in cross-section about U-shaped and can be plugged onto an edge of the backrest. In a cushion part of the headrest, a clamping arm with an outer and an inner arm portion is embedded, wherein the two largely dimensionally stable portions are connected to each other via a spring-loaded hinge and pivotable into an open position.

JP 2001 340159 A discloses a neck support for a chair with backrest, which neck support in the transverse profile about U-shaped and can be plugged onto the upper edge of the backrest, wherein it forms a U-shape forming, largely dimensionally stable shell, which with respect to the U-shape on the outside with one is provided by common upholstery.

PRESENTATION OF THE INVENTION

Object of the present invention is to provide a chair of the type mentioned, which in particular easily and efficiently produced and thereby is inexpensive and on the backrest a neck support can be fixed in a simple manner so that it is secured against accidental removal, but still can be removed with a few simple steps again.

This object is achieved by the features specified in patent claim 1. The core of the invention is therefore that the plate-shaped stiffener with some distance from the upper edge of the backrest back with at least one, the thickness of the posture bridging there first fixing dome for a Einhängeknopf and front side with at least one, the thickness of the padding there also bridging second Fastening dome for a push button or a corresponding push-button eyelet are formed

A neck support which is preferred for the chair according to the invention comprises two dimensionally stable shells, essentially forming the legs of the U-shape, pivotally connected to one another in an open position, which are provided with a continuous padding on the outside with respect to the U-shape.

By the two largely dimensionally stable, mutually pivotable shells, the padding can already be mounted very efficiently, e.g. the outer upholstery fabric (or the outer upholstery leather) after attaching a soft cushion pad on the outsides of the two shells from the outside pulled over this and stretched and then inside (in the U-shape) is attached to the shells. This attachment can be achieved by conventional means such as e.g. Antackem also run very easily, when the two shells are pivoted into their open position. The two shells also guarantee that the upholstery and neck support remain "in shape" overall, even when subjected to intense stress over a long period of time.

The two shells can be advantageously plastic injection molded parts.

In a die-casting production, the two shells can even be made in a single operation as a one-piece part, the connection between them, which allows a pivot against each other, can be realized in the form of at least one film hinge.

To attach the above neck support on the upper edge of the backrest of the inventive chair, it may be provided on one leg with at least one keyhole-shaped Einhängeöffnung and on its other leg with at least one push button or a corresponding push-button lug a push-button connection, in this embodiment of the Pivotility of the two shells against each other partly made use of again. In this design, the neck support for attachment to the upper edge of the backrest namely, first with its at least one, keyhole-shaped Einhängeöffnung on the at least one suitably placed on the back of the backrest and hooked by this above Einhängeknopf and then secured by gently pulling up on the Einhängeknopf , Thereafter, it is folded over the upper edge of the backrest in its U-shape and finally fixed by pressing the at least one push-button connection on the opposite front of the backrest, but here again easily detachable.

The suspension connection is placed on the back of the back so that it does not come off when e.g. The entire chair should be grasped from behind on the neck support and moved with it.

WAYS FOR CARRYING OUT THE INVENTION

In the FIGS. 1 . 2 and 5 1 denotes the backrest of a chair provided with a plate-shaped reinforcement 2 and a padding 3, and 4 a neck support which is placed on its upper edge and approximately U-shaped in cross-section.

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

The two shells 5, 6 are made as a largely dimensionally stable plastic injection molded parts together and in one piece and pivotally connected to each other via two sharpening technically the same with trained film hinges 8.

Fig. 3 shows the two shells 5, 6 in unfolded and Fig. 4 in folded position.

The existing of a foam blanket and a cover padding 7 of the neck support 4 is held by the two shells 5, 6 in the form. 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 additionally attached to the backrest 1. On its rear shell 5 are on the one hand two keyhole-shaped Einhängeöffnungen 9 is formed, which can be hung in Einhängeknöpfe 10 on the back of the back and can be secured by moving against hanging. On the other hand, two push-button eyelets 11 are provided on the front shell 6, which cooperate with two push buttons 12 on the backrest front. The push buttons 12 are arranged at a height such that the push-button connection 11, 12 can only be closed when the rear-side suspension connections 9, 10 are in their secured against unhooking position. Thus, the neck support 4 can be easily removed at will from the backrest. When attaching as when removing and closing or releasing the push-button connection their Aufklappbarkeit from the u-shape of additional advantage.

Like this in Fig. 2 can be seen, the Einhängeknöpfe 10 are fixed in Befestigungsdomen 13, which are formed on the back of the plate-shaped stiffener 2 of the backrest 1 and also bridge the padding 3 of the backrest. The push buttons 12 are fixed in corresponding, on the front side on the plate-shaped stiffener 2 of the backrest 1 molded Befestigungsdomen 14, which also bridge there the upholstery 3 of the backrest 1.

The plate-shaped stiffener 2 of the backrest 1 can be made, for example, from a foamed in a mold plastic material. The attachment domes 13, 14 can be molded with no additional effort by appropriate design of the mold.

Fig. 5 shows an overall view of the backrest 1 with attached neck support 4, as it is visually presented from the front.
