Definitions

  • the known headrests have the disadvantage that the user does not it is possible to work in the reclined posture on the monitor because it is the Do not support the head or neck precisely so that a head posture is supported, which enables a practical viewing angle to the monitor.
  • the invention tries to overcome this disadvantage of the known state of the art Avoid technology. It is based on the task of a neck support for to develop an office swivel chair with which it is possible to Support the user even in the reclined position so that a ergonomically correct viewing angle to the monitor is given. It should be an individual precisely adapted support of the neck for different work situations will be realized.
  • this is also the case for a headrest for an office swivel chair a movably mounted on a support for the purpose of inclination adjustment Backrest and with one between the backrest and neck support arranged hinge connection with an inclination resistance for adjustment the inclination of the neck support is achieved in that the neck support in addition is adjustable in height, the height adjustment following a circular orbit is formed, and the inclination adjustment resistance of the neck support is adjustable.
  • the advantages of the invention are that it combines Tilt and height adjustment of the neck support is possible at any time, precise support of the Realize head and neck area and thus an ergonomically correct Setting the viewing angle to the monitor. Neck tension will be with the user thus prevented. Due to the individually adjustable inclination resistance of the Inclination joint is advantageously left to the user to set, how stiff the joint should be.
  • the headrest with a supporting frame two curved side webs, each with a joint socket, as well as with a traverse and consists of a curved upholstery part, consisting of a U-shaped upholstery plate with sliding blocks and the upholstery itself, the side webs an inner guide groove for receiving the Have sliding blocks of the upholstery plate and the traverse has a central one Has guideway for additional guidance of the cushion plate.
  • This Way can be done very simply by moving the pad in the guide groove the height of the neck support can be adjusted.
  • the backrest has a backrest frame with two Has acetabular cups, which with the acetabular cups of the frame Neck support correspond, being in the socket of the Backrest frame are each axially arranged, which two by means of the socket of the frame of the backrest and the Frame of the neck support connecting screw connection are prestressed.
  • the U-shaped one advantageously has on the one hand Upholstery plate of the headrest in order to open its webs at the top Film hinge on. This means that it, including the upholstered part, can be easily moved over the Traverse of the headrest frame are brought.
  • they are Bridges at their lower end by means of connecting means, preferably Screws, connectable so that the upholstery part is firmly attached to the frame and does not slip during use.
  • FIG. 1 shows an office swivel chair 1 with a neck support 2 according to the invention while in use at a computer workstation.
  • the office swivel chair 1 has a backrest 4 movably mounted on a carrier 3. This The inclination of the backrest 4 is adjustable.
  • the backrest 4 and the Neck support 2 are via an articulated connection 5, which is shown in more detail in FIG. 4 is described.
  • a user is sitting especially when working on a monitor 6 in a reclined posture Office swivel chair.
  • an ergonomically correct viewing angle to Monitor is given, i.e. the top edge of the monitor 6 and the The user's eye level is on an (imaginary) horizontal Line of sight 7.
  • Fig. 2 shows schematically in a side view the height adjustability and Fig.3 the Tilt adjustability of the neck support according to the invention 2. From the Neck support 2 are only the curved side parts 8 of the frame and to see the curved upholstery part 9. In addition, the articulation 5 between neck support 2 and backrest 4 shown.
  • the solid ones Lines in Fig. 2 show the headrest 2 in the retracted position (lowest height) of the upholstery part 9, the dashed lines in the highest Position. Due to the curved components, the height adjustment follows one Circular orbit (see dash-dot line).
  • Fig. 3 the headrest 2 is shown in a standard position (solid lines), the dashed lines show them in a forward direction Position inclined towards the user.
  • Fig. 4 shows a partial longitudinal section through the neck support and backrest support of the office swivel chair 1, from which the exact structure of the invention Neck support 2 emerges.
  • the neck support 2 consists of a load-bearing Frame with two circular segment-shaped side webs 8, of which for reasons of symmetry, only one web 8 is shown in FIG. 4, as well as one Crosspieces 8 connecting cross member 10 and a curved cushion part 9.
  • Das Upholstery part 9 consists of a U-shaped pad 11 and the pad 12 self.
  • the side webs 8 of the neck support frame have at their lower end one socket 16 each. They also have an inside Guide groove 13.
  • the cushion plate 11 is laterally with slot nuts 14 provided which are guided in the guide groove 13.
  • the cross member 10 has a centrally arranged guideway 15 in which the cushion plate 11 is additionally performed. By moving the cushion plate 11 in the Guide groove 13 or guide track 15 is thus the height adjustment of the Neck rest 2 realized.
  • the backrest 4 has a backrest frame 17 with two joint sockets 18, which with the two joint sockets 16 on the side webs 8 of the Neck support 2 correspond.
  • two plate springs 19 are arranged axially.
  • a screw connection 20 holds the two joint sockets 16, 18 together, on the other hand, it serves to preload the plate springs 19 in such a way that a certain coefficient of friction between the two joint sockets 16 of the Frame of the neck support 2 and the two joint sockets 18 on the Backrest 4 takes effect and so a certain resistance Inclination adjustment results.
  • the resistance of the tilt joint 5 is necessary so that the neck support on the one hand holds the head weight and on the other hand allows a situational adjustment of the inclination. With the The solution according to the invention can thus be used individually by a user of the office chair adjust how stiff the joint can be adjusted.
  • Fig. 5 shows a side view of the neck support 2 with mounting components 21, 22.
  • the neck support 2 is on the U-shaped Upholstery plate 11 a film hinge 21 for the purpose of opening its webs arranged.
  • the U-shaped cushion part 9 unfolded and simply over the cross member 10 of the frame of the Neck support 2 are brought.
  • the two webs of the Upholstery part 9 from below by means of connecting elements 22, here screws, connected to each other so that the cushion part is firmly attached to the frame and does not slip during use.
