ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to sitting furniture and more particularly, to a neckrest, for a chair having backrest, configured to be attached to a backrest shield in a height-adjustable manner, the neckrest including a circular cross-section retaining rod, configured to be connected to the backrest shield in an articulating or movable manner so as to be tiltable by up to approximately 30° in a vertical plane vertically with respect to a surface of the backrest, and a circular cross-section guide sleeve, mounted on the retaining rod so as to be slidingly shiftable by up to approximately 200 mm on the retaining rod.
2. Discussion of Background
It is known that the user of a chair, in particular an office chair or other type of work-related chair, often has the need for relaxation, which the user may accomplish by leaning back. According to the latest medical findings, optimal relaxation is achieved with an angle of opening between upper and lower body of about 25°. For this purpose, many chairs are equipped with a tiltable backrest.
One type of chair having a tiltable backrest is a so-called “high-back” chair. These “high-back” chairs often have the problem that the upper part of the backrest also supports the head or the neck, and this support of the head or the neck cannot be adjusted to the individual requirements of the user. Further, in the case of chairs with a low backrest, the headrest cannot be brought easily into the area of the head of the user.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a neckrest for a chair having a backrest which is designed in such a way that the neckrest can be attached inconspicuously and aesthetically on the back shield of a chair with backrest, but that nevertheless the headrest covers the entire angular range, within which the user wants to rest his head against the pad. Furthermore, the neckrest of the present invention should be able to be manufactured in production with little effort and easily mountable on the chair having the backrest.
The above-stated objective is accomplished with by the neckrest of the present invention, wherein the neckrest is for a chair having a backrest, the neckrest configured to be attached to a backrest shield in a height-adjustable manner. The neckrest including a circular cross-section retaining rod, configured to be connected to the backrest shield in an articulating manner so as to be tiltable by up to 30° in a vertical plane vertically with respect to a surface of the backrest, and a circular cross-section guide sleeve, mounted on the retaining rod so as to be slidingly shiftable by up to 200 mm on the retaining rod.
In other words, the neckrest of the present invention includes connecting the headrest of the chair on a guide sleeve that slides on a retaining rod, fastening the retaining rod on the back shield through a simple joint in a tiltable manner, and designing the retaining rod and guide sleeve so as to have circular cross-sections. On the one hand, this allows the user to adjust the desired inclination of the neckrest in a simple manner. On the other hand, the height of the neckrest in also adjustable. It is very important that the retaining rod and the guide sleeve are designed so as to have circular cross-sections because, unlike a straight retaining rod, the circular cross-section retaining rod allows for an adjustment of the optimal distance of the headrest from the head of the user.
