Definitions

the invention relates to the field of seating, in particular a neck support for a chair for the office area.
a neck rest for an office chair is known from, for example EP 1'192'880 A2.
This neck support has a holding rod on the back of the The back of the chair is hinged, and one slides on this support bar Guide sleeve, on the upper end of which the head cushion is attached.
retaining bar and the guide sleeve are designed in the shape of a circular arc.
the distance of the Head cushion to the head or neck of the user is mainly by a Swiveled the support rod around the spherical bearing on the backrest changed.
such a change also occurs with a height adjustment of the head cushion by sliding the guide sleeve on the holding rod because of the circular path of movement.
Another neck support is known from EP 1'186'257 A2. At this Neck support is an arc-shaped support rod at the top of the Articulated backrest, on which a likewise circular arc Guide sleeve, which is integrated in the head cushion, can slide up and down.
This neck support has also proven itself, but shows how the former, the disadvantage of that the removal of the head cushion from the head the user cannot be set in an optimally large range.
the object of the invention to provide a neck support for a chair, in particular an office chair, to be developed in such a way that on the one hand aesthetically pleasing discreet and without excessive manufacturing and Assembly effort can be attached to the backrest, on the other hand nevertheless has a large adjustment range for the user's head.
the neck support should also have these properties during assembly have on a height-adjustable and reclining backrest.
the essence of the invention is the idea of articulating a straight holding rod on the Tie the top edge of the backrest, and slidable on this provide straight guide sleeve, at the upper end of which the head cushion is articulated.
the pivoting range of the support rod should be from the direction of the Lean from approximately 35 ° to the front, the head cushion approximately 40 °.
the neck support can then be used in the technical area Detail can be designed so that it is aesthetically pleasing and without great Effort can be produced and assembled, and in particular together with an in the height and inclination adjustable backrest an optimal adjustment range for gives the user.
the holding rod 2 and the guide sleeve 4 extend the backrest 1, that is to say vertically upwards in the figure, the guide sleeve 4 occupies its lowest position.
the guide sleeve 4 is in the second position also vertical, but in its highest position.
the guide sleeve 4 is inclined forward, and the head cushion 6 is once in the deepest and once in the highest Position.
the swivel range around the lower spherical bearing 3 should be approximately 35 °, which amount to about 40 ° around the upper spherical bearing.
the length of the Extraction of the guide sleeve 4 on the holding rod 2 is approximately 70 mm. This Short extension length is not only due to the attachment of the neck support to one incline, but also height-adjustable backrest possible: the rough adjustment can then be made with the back of the chair, and the Adjustment of the neck support is only for fine adjustment. Total results a remarkable range of settings.
the holding rod 2 forms a cylinder 7 at the bottom Has.
This cylinder 7 is in the assembled state between the cylinder 8 and the cylinder 9, both of which are molded onto the upper end of the bearing base 10.
the two sliding blocks 13 together with the spiral spring 28 inserted into the cylinder 7 and pressed against each other. Then the Cylinder 7 placed between cylinders 8 and 9 and the pressure on spring 28 taken away. As a result, the sliding blocks 13 enter the cylinders 8 and 9, and the holding rod 2 is thus articulated.
the cylinder 7 on the holding rod 2 has one such an internal shape that the sliding blocks 13 do not rotate can. In the cylinder 8 or 9, however, the shape is such that the Slide blocks 13 have a turning space between the stops 14, which the Pivoting the holding rod 2 allows.
the structure of the upper spherical bearing 5 is basically identical to that described construction of the lower spherical bearing 3. It is therefore not yet once described, and the corresponding parts do not have any own reference numerals. This camp is different, however, in that the Cylinders 8 and 9 corresponding cylinders are attached to the tab 26, which are fastened to the frame 23 of the head cushion 6 by means of the screws 27 become.
the movement of the guide sleeve 4 on the holding rod 2 is due to the slide rings 21 stabilized. These have sliding knobs 24, and engage in after assembly the notches 22 of the holding rod 2.
the clip 20 slides in the guide slot 19 and grips with its nose into the recess 25 of the guide sleeve 4, and thus serves as a pull-out protection for the sliding on the holding rod 2 Guide sleeve 4.
the head cushion 6 is held on a frame 23 becomes.
it is preferably made of plastic Frame 23 for producing the head cushion 6 in polyurethane (PUR) foamed.
PUR polyurethane
Fig. 3 the neck support according to the invention is shown in the assembled state.
the parts already described are also easy to assemble understandable and are therefore not described again.
the bearing base 10 is in the shaft 11 of the sword Backrest plate 12.
the bottom of the bearing has one Latch 17, which engages in the recess 18 of the backrest plate 12 and the bearing base 10 thus firmly anchored.
the mounting of the headrest on the The top edge of the backrest 1 is therefore extremely simple, but nevertheless safe.
the neck support according to the invention due to their linear height adjustment and their swiveling by two bearings Provides maximum comfort for the user, but still with is relatively easy to manufacture and assemble.
