Definitions
- the invention relates to a medical chair with a backrest attached to the seat by means of a backrest support and an adjustment device adjusting the backrest support.
- Such a chair is known from DE 4210359A1.
- the backrest is designed as a bracket, and the adjusting device is formed by four seat supporting the telescopic legs.
- the adjustment of the adjustment device is very cumbersome, but four legs must be changed.
- DE 871 1717 discloses a chair with a height-adjustable seat and an independently adjustable back rest, in which performance of the lumbar lordosis of the user's seat is adjustable in its inclination forward and the back comprises a transverse lumbar roll to support the lumbar lordosis.
- the rear edge of the seat is raised.
- the distance between the seat and the lumbar roller is shortened so that the backrest no longer fixes the back in the middle lumbar region.
- the diameter of the lumbar roll and its shape are limited.
- the lower portion of the lumbar roller is rotated on its bearing support on the back support support on a circular arc and simultaneously moved forward and upward, so that it is out of the ideal position with respect to the lumbar lordosis.
- the object of the invention is to provide a medical chair of the type mentioned, which makes it possible that the backrest can be easily brought to any points of the back and that the disadvantages of the prior art are avoided. This is achieved with the characterizing features of claim 1.
- the backrest support is formed by a vertical sleeve which can be displaced horizontally on the rod and in which the telescopic support is adjustably mounted. This allows vertical adjustment of the back support.
- the pad is, for example, a cylindrical, horizontal roller with a straight or curved cylinder axis extending, a ball or an ellipsoid.
- the term horizontal refers in this case in connection with the rod and the sleeve which can be displaced along its longitudinal axis to the surface of the seat, in particular one through the seat, for example by its at least partially For example, level bottom spanned plane.
- the term horizontal refers to the horizontal orientation of the cylinder axis of the substantially cylindrical roller or a semi-axis of the ellipsoid.
- the latter is preferably one or the large semiaxis of a triaxial ellipsoid and / or the axis of rotation of an ellipsoid of revolution, in particular also an elongated ellipsoid of revolution having a pointed end corresponding in shape to a football.
- axis in contrast to the term shaft, denotes a geometric axis and not a machine element
- Fig. 1 shows a first embodiment of a medical chair with a person supported in the back in a side view.
- FIG. 2 is a front view of the chair of FIG. 1.
- FIG. 2 is a front view of the chair of FIG. 1.
- Fig. 3 is a plan view of the chair of Fig.1.
- Fig. 4 shows a second embodiment of a medical chair with a person supported in the back in a side view.
- FIG 5 is a front view of the chair of FIG .. 4
- Fig. 6 shows a third embodiment of a medical chair with a person supported in the back in a side view.
- FIG. 7 is a front view of the chair of FIG .. 6
- FIG. 8 shows a fourth exemplary embodiment of a medical chair with a person supported in the back in a side view.
- FIG. 9 is a plan view of the chair of FIG. 8th
- Fig. 10 shows a fifth embodiment of a medical chair in a
- 1 1 is a plan view of the chair of FIG. 10th
- FIG. 1 -1 medical chair has a seat 1, on which a person, for example, a back-damaged patient sits. This person should be treated in the back in certain places.
- a lower seat part 2 is fixed in the form of a plate, in the middle of which a roller 3.1 -3.5 carrying telescopic support 4 is fixed downwards.
- This telescopic support can be adjusted vertically in a known manner.
- the chair On the rollers 3, the chair is movable.
- the lower seat part 2 further comprises a rear horizontal bar 5, on which a vertical sleeve 6 is horizontally displaceable.
- a backrest support 7 is mounted vertically displaceable.
- This carries at the end facing the back of the person a back support 8, which, for example, as shown in FIGS. represents as a straight, horizontal, cushioned role, as shown in Fig. 8-9 as a convex, horizontal, cushioned role, as shown in Fig. 10-1 1 as a ball, or may be formed as an ellipsoid. This allows any anatomy in the lumbar area of a user to be replicated.
- the lower seat part 2 and its rear, horizontal bar 5 are arranged without pivoting and unverkippbar parallel to a plane defined by the seat 1 level. Compared to the seat 1, the lower seat part 2 and the rear, horizontal bar 5 are arranged without swiveling and unverkippbar.
- the horizontal bar 5 extends at a constant distance below the plane defined by the seat 1 level.
- the rod 5 over its entire length the same distance to the plane spanned by the seat 1 level.
- the horizontal bar 5 thus always has the same distance with respect to the plane spanned by the seat 1 with respect to the rear edge 9 of the seat 1 facing the backrest support 7.
- a backrest formed by the vertical sleeve 6, the backrest support 7 mounted vertically displaceably in the latter and the backrest 8 arranged on the backrest support 7 is thus fastened in relation to the rear edge 9 of the seat 1 in such a way that an optionally provided adjustment of the inclination of the seat Seat 1 to the horizontal does not affect the distance between the back support 8 and rear edge 9 of the seat 1. Accordingly, the distance between the back support 8 and trailing edge 9 of the seat 1 normal to the plane defined by the seat 1 is free from an influence of a change in inclination of the seat 1 relative to the horizontal.
- the short referred to as a foot point formed by the along the longitudinal axis of the rod 5 movable portion of the sleeve 6 connecting point between the sleeve 6 and the rod 5 at a constant distance to the plane defined by the seat 1 on the lower seat part 2 extending, with its longitudinal axis parallel arranged to run from the seat 1 plane extending horizontal rod 5.
- the extending the lower seat part 2, with its longitudinal axis parallel to the plane spanned by the seat 1 extending horizontal bar 5 is arranged without tilting and unverkinkbar against the plane spanned by the seat 1 level.
- the terms relate horizontally and vertically with respect to the rod 5 and the sleeve 6 in an optionally provided tilt adjustment of the seat to the plane spanned by the seat 1 level.
- horizontal bar 5 relative to the seat 1 is a change in inclination of the seat 1 with a change in inclination of the lower seat part 2 and the rear rod 5 including parallel to the plane spanned by the seat 1 along the longitudinal axis of the rod 5 slidable sleeve 6 accompanied.
- the inclination of the lower seat part 2 together with the rear rod 5 and the seat 1 arranged parallel to this can be adjustable relative to the horizontal.
- the seat 1 can be slidably arranged there on the lower seat part 2 parallel to the plane spanned by the seat along the longitudinal axis of the horizontal bar 5 by a double arrow P.
- the seat 1 is in this case arranged displaceably on the lower seat part 2 along a displacement axis extending within a plane defined by the longitudinal axis of the telescopic support 4 and the longitudinal axis of the horizontal bar 5.
- the displacement axis preferably runs at a right angle to the axis of the telescopic support 4. It can alternatively run at a slight inclination relative to the horizontal.
- the displacement axis runs parallel to the longitudinal axis of the horizontal bar 5.
- the inclination of the displacement axis relative to the horizontal and with it the inclination of the lower seat part 2 and of the seat 1 displaceable parallel to this relative to the horizontal can be adjustable.
- the inclination of the backrest formed by the vertical sleeve 6, the backrest support 7 mounted vertically displaceably and the backrest 8 arranged on the backrest support 7 can be variable.
- the sleeve 6 with its the foot of the backrest forming along the longitudinal axis of the rod 5 movable portion at the same time with respect to the rod 5 about a parallel to the rear edge 9 of the seat 1 extending, horizontal pivot axis be pivotable.
- a joint 1 1 which can be fixed for example by means of a toggle 12, may be provided in the backrest support 7.
- the joint 1 1 has a horizontal, normal to the plane defined by the longitudinal axes of the rod 5 and the telescopic support 4 plane extending hinge axis.
- the hinge 1 1 allows pivoting of the back support 8 supporting the upper part of the backrest support 7 with respect to a remaining, in the sleeve 6 vertically displaceably arranged part of the backrest support 7th
- the back support 8 may be formed by a preferably cushioned cylindrical roller whose cylinder axis is straight and extends horizontally.
- FIGS. 8-9 An alternative embodiment, shown in FIGS. 8-9, of a back support 8 formed by a preferably cushioned cylindrical roller has a cylinder axis which is convex to the seat 1 or to a person seated on the seat 1.
- the cylinder axis may in this case lie within a plane extending parallel to the plane defined by the seat 1. This results in a horizontal, convex curvature of the back support 8.
- a vertical convex curvature of the back support 8 may be provided.
- a combination of a horizontal, convex curvature and a vertical convex curvature of the back support 8 leads via, for example, ellipsoids of revolution to the embodiment of a spherical back support 8 illustrated in FIG. 10-1.
- the back support 8 can be arranged, for example, by means of Velcro releasably on the back support support 7. In this way, the back support 8 can be easily replaced, for example, to adapt about the radius and / or the curvature of the back support 8 to a place on the medical chair taking person and / or preferred by a person geometric shape and / or preferred by a person Hardness of their upholstery. In addition, Take the back support 8 to be easily cleaned and / or a removable cover, for example, changed or washed.
- the back support support 7 may have, for example, a multi-finger-shaped receptacle facing away from the seat 1, upper end.
- the fingers may be provided for releasable attachment with hook and loop elements, preferably those which should not be subjected to a wash cycle.
- the same fingers may be provided to be encapsulated by foam, for example, during a foaming process.
- an automatic brake and / or blockage of the rollers 3.1 -3.5 may be provided at vertical load of the telescopic support 4.
