Definitions
- the invention relates to headrests or neckrests for seating of any kind.
- Known headrests may provide a pleasant feeling of relaxation, but orthopedically, it is desirable that the leaning against the backrest is effectively relieved of the cervical spine of the person leaning back.
- Such headrests have not yet been implemented in the prior art.
- a headrest should be designed so that it corresponds to today's orthopedic adjustments.
- the neck support in the support area is essentially in the form of a double cone or a double-shell hyperboloid built up.
- a backward movement of the body of the seated person from the support in the support area can exert an upward force on the back of the head if a relative movement arises which slightly raises the head.
- This relative movement is achieved according to the invention by the shape and arrangement of the support rods, as will be explained further below.
- the upward force on the back of the head relieves the pressure on the cervical spine and fulfills the task on which the invention is based.
- Fig. 1 shows a perspective side view of a chair with a headrest according to the invention.
- Fig. 2 shows an embodiment of the front view of the upper part of the headrest according to the invention.
- Fig. 3 shows a further embodiment in the front view.
- Fig. 4 shows an embodiment seen in perspective from the front.
- Fig. 5 shows the embodiment of FIG. 4 in front view.
- 6 and 7 are sections of the embodiment of FIG. 5.
- 1 to 5 consist essentially of two cones 1, 2 facing each other with the tips, which essentially consist of foam.
- the cones can acc. Fig. 3 rounded or gem.
- Fig. 4 and 5 assume a pear-shaped shape, the latter form of leadership in the outer part run upwards, since there is no protective function below. All the shapes of the foam part of the headrest presented here lie under the back of the head so that when moving upwards the head can really be raised and the cervical spine is relieved.
- the axis of rotation of the seated person In order to meet the second condition of relieving the cervical spine, to achieve a relative movement of the headrest upwards when leaning against it, the axis of rotation of the seated person must lie in front of the axis of rotation of the movement of the headrest, as shown in FIG. 1 as a basic example.
- P is the axis of rotation of the seated person when leaning back
- 11 is the axis of rotation of the headrest.
- the circle of motion 30 of the headrest is thus visibly above the circle of motion 31 of the head of the seated person, which causes the desired relative movement.
- the axis of rotation of the headrest can also be higher.
- the axes of rotation shown here are axes of rotation of the headrest when springing back elastically.
- Fig. 6 also achieve by the asymmetrical shape with respect to the horizontal axis of the holding device 12 when there is rotated from position I to position II.
- the vertical part of the rod 12 ensures by friction on the surface 13 for fixing the position of the foam part. If this foam part is pushed back when the impact is too strong, it goes up relative to the head, which, as shown above, is desirable.
- This type of attachment of the foam parts is also gem for the embodiments. 3, 4 and 5 possible.
- brackets 12 are gem. 3 and 4 in the form of an inverted U are preferred. Fixing in different inclinations and resilient springing back about rotation axes, behind those of the seated person, as shown above, is possible with both brackets.
- Fig. 1 the actual seating area is indicated by 10.
- Backrests in particular backrests, are not shown in the figures.
- inserts are possible as they correspond to the prior art.
- the axis for the two support parts is curved.
- the two support parts according to the invention can also be adjustable about a horizontal axis, preferably so that the pear-shaped support parts can be moved forward in the upper region if this is desired due to the anatomical conditions. It is essential for the present invention that in a motor vehicle, in a dangerous situation, the impact energy is largely converted into energy which the spine of the person concerned takes in the direction of pull.
