In order to enable said seating arrangement to be adapted to different working positions in an orthopedically favorable manner, according to the invention the stand or the seating (10) unit is provided with an additional seating surface (35). The additional seating surface can be adjusted from a rest position to an upright-seating position.

Description

seat

The invention relates to a seat, in particular a chair with a frame, which carries a seat unit with a seat.

Such seating is well known. For orthopedic reasons, it is advisable not to perform activities that are not sitting alone. Rather, there should be a change between sitting and standing work. With standing activity, relief of the spine is achieved in particular if you lean backwards.

It is an object of the invention to provide a seat of the type mentioned at the outset which can be adjusted to different working conditions in an orthopedically advantageous manner.

This object is achieved in that the frame or the seat unit is one

Has additional seat, and that the additional seat from a resting

bestätigunskopie position is adjustable in a standing-sitting position. With this seat, a user can either sit on the actual seat or on the additional seat

Take a seat. If necessary, he can make the additional seating area easily accessible by moving it from the rest position to the standing / sitting position.

According to a preferred embodiment of the invention, it is provided that the seat unit has a backrest which holds the additional seat. The backrest can be manufactured together with the additional seat as a unit, for example as a plastic shell.

It can in particular be provided that the additional seat is integrally formed on the backrest and protrudes toward the back of the seat in the rest position. In the rest position, the additional seat does not hinder the accessibility of the actual seat.

A possible variant of the invention is such that the seat unit by means of a

Articulated connection is pivotally coupled to the frame, and / or that the backrest is articulated to the seat surface. It is also conceivable that the backrest alone is articulated to the seat. Via the swivel connections designed in this way, the additional seat can be accessed by adjusting the seat unit or the backrest. So that the additional seating area can be adapted to users of different sizes, it can be provided that an adjustment device is coupled to the additional seating area and that different height orientations of the additional seating area can be adjusted by means of the adjustment device. The adjusting device can be designed differently. For example, a seat can be characterized in that one on the frame

Armrest is coupled, that the armrest has a guide in which an actuator is guided, and that the actuator is coupled to the additional seat and in the guide between a rest position position and optionally at least two positions of the standing-sitting position and adjustable.

According to an alternative solution, it can also be provided that a handlebar is coupled to the frame and the additional seat surface by means of articulated connections, that the adjusting device can be assigned to one of the articulated connections, and that the articulation point in the respective articulated connection between at least two adjustment positions by means of the adjusting device is adjustable relative to the frame or the additional seat.

A preferred embodiment of the invention is characterized in that the frame has a pivotable carrier that holds the backrest with the additional seat, and that the carrier can be pivoted from the sitting position into the standing-sitting position. The additional seat is no longer connected to the seat. This means that the design and attachment for the seat can be carried out without being influenced by the swivel arrangement for the additional seat. The direct introduction of the forces acting on the additional seat into the frame also offers stability advantages.

The height adjustment of the additional seat surface can be carried out in a simple manner in such a way that the carrier or the backrest has at least one actuator which, in the standing-seat position, can optionally be inserted into one of at least two positioning receptacles of the adjusting device. Preferably, it can also be provided that the carrier is linearly displaceable in a longitudinal guide, that the longitudinal guide is opposite the

Horizontal is inclined, and that the actuator has different height orientations when the carrier is adjusted in the longitudinal guide.

To reduce the construction effort, it can be provided that the carrier has a spar which is arranged above the seat surface and which supports the backrest including the additional seat surface, that the carrier is connected to the frame by means of an articulated connection below the seat surface, and that the carrier is guided to the side of the seat surface or protrudes through an opening in the seat surface.

An alternative design for the height alignment of the additional seat surface can be designed according to the invention in such a way that the frame has a lifting mechanism by means of which both the seat surface and the additional seat surface can be changed in their height orientation. Two functions can thus be realized with such known lifting mechanisms.

In order to prevent the seat from being shifted relative to the floor in the loaded state, but in the unloaded state, on the other hand, it can easily be moved on the floor, it is provided that the frame is supported on the floor in the region of its feet by means of sliding pieces or rollers the track pieces or rollers are supported against the pretension of spring elements with respect to the feet and that the frame has at least one stopper which sits on the floor when the spring element is compressed. The invention is explained in more detail below on the basis of exemplary embodiments illustrated in the drawings. Show it:

Position of the foot.

1 shows a cantilever chair. The cantilever chair has a 0 frame 1 0 and a seat unit 30. The frame 1 0 has two horizontal feet 1 1, which are connected to one another via a connecting profile 1 2. On the front, chair legs 1 3 are attached to the two feet 1 1. The chair legs 1 3 pass at their ends facing away from the feet 1 1 into an oblique bend 1 4. The bend 14 carries an end section 1 5 an actuating unit 20 is attached to this end section 15. For this purpose, the actuating unit 20 has an attachment 23 with a receptacle. The setting unit 20 can be plugged onto the end section 15 by means of the receptacle. The actuating unit 20 has an armrest 21 which is connected in an articulated manner to the seat unit 30 at its end facing away from the attachment 23. The connection is made by means of an actuator 22 which is coupled to a backrest 34 of the seat unit 30 at the rear. Since the chair is constructed symmetrically, it has two armrests 21 and, accordingly, two actuators 22. The actuators 22 are inserted into a guide 24 of the actuating unit 20. The guide 24 is designed as a slot or slot. The bolt-shaped actuator 22 can be guided in this. At its end facing the shoulder 23, the guide 24 widens and forms an adjusting device 25. The adjusting device 24 has three positioning receptacles that are vertically spaced apart.

The seat unit 30 has a horizontal seat surface 31 which is coupled to the frame 10 at the front by means of a joint 32. The hinge 32 forms a horizontal pivot axis. The two are used to stiffen the joint area

Chair legs 1 3 connected with a connecting profile 1 2. The backrest 34 is connected to the seat 31 at the rear via a connecting section 33. The connecting section 33 is designed as a hinge, the hinge axis also being oriented horizontally. The backrest 34 can be folded relative to the seat 31 by means of the hinge. An additional seat 35 is angled from the backrest 34. The additional seat 35 is arcuate and integrally connected to the backrest 34. It protrudes toward the back of the chair over the backrest 34. The in Fig. 1 cantilever chair shown can be converted, making the additional seat 35 accessible. For this purpose, the backrest 34 is gripped and pulled towards the front. The actuator 22 slides along in the arcuate guide 24 until it reaches the upper positioning receptacle of the adjusting device 25. This setting position is shown in FIG. 2.

As can be seen from FIG. 2, the setting position shown forms a standing-sitting position, in which the additional seat 35 is accessible. A user can take a seat or lean on the additional seat 35.

In order to be able to adapt the cantilever chair to users of different sizes, the actuator 22 can be moved in the adjusting device 25. For this purpose, the actuator 22 must be moved out of the positioning receptacle into the guide 24. Then the backrest 34 can be pressed down together with the additional seat 35. The angle formed between the seat surface 31 and the backrest 34 in the region of the connecting section 33 is reduced. At the desired altitude, the actuator 22 can then be reinserted into the associated positioning receptacle of the adjusting device 25.

As can be seen in FIG. 1, the joint 32 and the connecting section 33 form a joint system which on the one hand enables the seat surface 31 to be pivoted and on the other hand enables the backrest 34 to be adjusted. If the user wants to make the seat 31 accessible again, then all he has to do is slide the backrest 34 out of the associated positioning receptacle of the adjusting device 25, so that it inevitably enters the guide 24. The actuator 22 can then be displaced in the guide 24 until it comes to rest securely at the end in a latching receptacle 26 of the guide 24.

3 shows a four-legged chair, which is based in principle on the same principle of action as the cantilever chair according to FIGS. 1 and 2.

In this chair, a frame 10 is used, which has four chair legs 13. The chair legs 13 are connected to one another with connecting profiles 12 running in the chair depth and width directions. The two rear chair legs 13 have an extension 16. The armrest 21 of the adjusting unit 22 is firmly coupled to this extension 16. In this chair too, the additional seat 35 can be made accessible solely by pivoting the seat 31 and the backrest 34. Because the way this works

Chair essentially corresponds to that of the chair according to FIGS. 1 and 2, reference should be made here to avoid repetitions to the above statements.

Another cantilever chair is shown in FIG. This cantilever chair has a frame 10 with two horizontal feet 1 1, which are connected to one another via a connecting profile 12. A rising chair leg 13 goes off from the feet 1 1. The angled portion 14, which underpins the seat surface 31, is connected to the chair leg 13. The bend 14 has one End section 1 5, to which an adjusting device 25 is coupled. The adjusting device 25 has a wheel which is coupled to a threaded spindle. A nut is adjustably guided on the threaded spindle. The mother carries a handlebar 29.1. The handlebar 29.1 is attached at its free end to the backrest 34 (articulated connection 29). In the area of the articulated connection 29 there is also an armrest 21 which is rigidly connected to the handlebar 29.1.

If the user wants to make the additional seat 35 accessible, he must pull the backrest 34 forward, as in the cantilever chair according to FIGS. 1 and 2, the seat 31 being inclined. If the additional seat 35 is to be adjusted to different user sizes, the wheel of the adjusting device 25 must be turned. This also rotates the spindle, causing the nut to move linearly. However, this also linearly displaces the articulated connection 27 via which the link 29.1 is coupled to the nut. As a result of this linear displacement, the inclination of the handlebar 29.1 can be adjusted, as a result of which the additional seat surface 35 has different height orientations.

5 shows a further embodiment variant of a seat. The frame 10 has a horizontal foot 1 1, which rests on the floor. The ascending chair leg 1 3 adjoins the foot 1 1 at an angle to the vertical. The angled portion 40, which is designed as a supporting piece, is in turn connected to the chair leg 1 3. The foot 1 1, the chair leg 1 3 and the

Bends 1 4 are made as one component, for example made of plastic or die-cast zinc. There are two of these per seat Units used that are in accordance with the image depth. Fig. 5 are placed one behind the other. They are connected to one another via the seat 31. However, it is also conceivable that a single component is used which extends essentially over the entire depth of the seat.

5 shows, the chair legs 1 3 are provided with a longitudinal guide 1 7. This longitudinal guide 1 7 is designed as a slot on the

Slot ends 1 7.1, 1 7.2 is limited. In the longitudinal guide 1 7 a bolt is guided, which can be moved back and forth between the slot ends 1 7.1 and 1 7.2.

The slot ends 1 7.1, 1 7.2 thus form stops for the bolt. The bolt forms an articulated connection 27. On this articulated connection 27, a support 18 is articulated. The carrier 1 8 is arranged below the seat 31.

A spar 19 protrudes above the seat 31 above the seat 31. The spar 1 9 is integrally connected to the carrier 18. On the spar 1 9 is the backrest

34 attached, which carries the additional seat 35 in one piece. The safe one

Underpinning of the additional seating area is accomplished by means of an attachment 1 9. 1. The approach 1 9.1 is integrally connected to the spar 1 9.

5 further shows, the carrier 1 8 has an actuator 22. This actuator 22 underpins the bend 14 and thus supports the seat unit 30. As already mentioned above, the carrier 1 8 can be pivoted about the articulated connection 27. In order to prevent the carrier 1 8 from tipping backwards, a stop 36 is provided on the seat unit 30. The spar 1 9 strikes this on the back. If the seat shown in FIG. 5 is to be structurally changed so that the additional seat 35 is accessible to a user, then only the support 18 in the articulated connection 27 has to be pivoted. The backrest 34 is guided to the front of the seat, as can be seen in FIG. 6. In the end position, the actuator 22 comes to rest in one of the positioning receptacles of the adjusting device 25. 6, the actuator 22 is inserted into the middle positioning receptacle. The dimensions are selected so that the actuator is usually first inserted into the lowest positioning receptacle during a pivoting movement. This is possible because the longitudinal guide 17 is inclined with respect to the vertical. Thus, the carrier 1 8 is held due to the weight at the lower end of the longitudinal guide 1 7, ie at the slot end 1 7.2. Now if one

Change in height of the additional seat 35 is desired, it only has to be gripped and pulled upwards. The bolt of the articulation 27 slides in the longitudinal guide 17 upwards. The actuator 22 can then be inserted into the desired positioning receptacle of the adjusting device 25.

If the user now wants to make the seating position accessible again, he only has to push the backrest 34 back. The carrier 1 8 then automatically slides down in the longitudinal guide 1 7. When pivoting, the actuator 22 runs on the guide 24 arranged at the bottom of the bend 14 until the spar 19 comes to rest on the stop 36. FIGS. 7 and 8 show two variants of a carrier 1 8.

7, the carrier 1 8 has two spars 1 9, which are guided to the side of the seat unit 31. When executing acc. Fig. 8 is a single spar 1 9 used. This protrudes through an opening 37 in the seat unit. The opening 37 is formed as a longitudinal slot in which the spar 19 can be moved back and forth when the additional seat surface 35 is pivoted.

A further embodiment variant of a seat is shown in FIG. 9. This seat differs only with regard to the design of the frame substructure compared to the seat shown in FIGS. 5 to 8. Accordingly, the frame has a central chair leg 1 3. The

Chair leg 1 3 is pivotally connected to a central foot 1 1 about a vertical axis.

10 shows a further embodiment variant of a seat. Here too, the structure and function are essentially in accordance with the

Seating according to FIGS. 5 to 9 executed. Again, a modified design of a frame 10 is realized. One or two front chair legs 1 3 and one or two rear chair legs 1 3 are used.

With the seat acc. Fig. 1 1 is a frame 1 0 used, which has a multi-legged frame base. This frame base has three or more feet 1 1. The frame 10 also has a lifting mechanism 50 which underpins the seat unit 30 centrally. To the lifting mechanism 50 is a Connecting piece 51 connected as a bracket 1 4 connected. In the area of the front of the seat, a joint 32 is provided which

Seat 31 articulates with the bend 14.

As can also be seen in FIG. 11, the connecting piece 51 carries an actuating mechanism 52 which, in a known manner, permits the backrest 34 to be pivoted to a limited extent. Accordingly, the backrest 34 can be moved from a steep upright position to a flatter backrest position. A lever 53 is connected to the adjusting mechanism 52 via a swivel joint 54. The lever is coupled to a link 29.1 via a connecting section 33. The handlebar 29.1 is connected at its end facing away from the lever 53 to the backrest 34 via an articulated connection 29.

If the additional seat 35 is now to be made accessible, it is gripped and pulled towards the front of the seat. Then, as can be seen in FIG. 1 2, the handlebar 29.1 pivots relative to the backrest 34. At the same time, the lever 53 also pivots against the

Adjustment mechanism 52 pivoted in the pivot 54. As a result of this pivoting movement, the seat surface 31 also inclines, which is possible with the joint 32. The type of pivoting is essentially similar to that of the design example of a seat according to FIG. 5, so that reference is made to the above statements in this regard.

Merely for the sake of completeness, it should be mentioned here that either one or two links 29.1 can be used for one seat. If two handlebars 29.1 are used, they are on the side next to the seat opportunity 31 led. A single link 29.1 is guided through an opening in the seat 31, similar to FIG. 8.

The end position in which the additional seat 35 is accessible is shown in FIG. 1 2. If the height of the additional seat 35 is to be adjusted, this can be done in a simple manner using the lifting mechanism 50. The seat acc. 1 1 and 1 2 can be carried out in such a way that a vertical axis of rotation is provided in the area of the lifting mechanism 50 or the connecting piece 51. The seat unit 30 can then be rotated about this.

1 3 and 14 is the design of a foot 1 1 for a

Seating according to FIGS. 1 to 1 2 in more detail. The foot 1 1 has a receptacle 1 1 .1 in which a spring element 1 1 .3 is inserted. In the area of the receptacle 1 1 .1, a bolt 1 1 .4 is also held, which carries a sliding foot 1 1 .2. The sliding foot 1 1 .2 is spring-biased relative to the foot 1 1. The spring preload is so great that when the sliding foot is loaded

1 1 .2 solely due to the weight of the seat, there is no or only a slight compression of the spring element 1 1 .3. A stopper 1 1 .5, for example a rubber stopper, is offset from the sliding foot 1 1 .2 by means of a threaded connection 1 1 .6 and is screwed into the foot 1 1. As can be seen in FIG. 1 3, the stopper 1 1, 5 is arranged at a distance from the floor. So that the seat can be adjusted on the floor using the sliding feet 1 1 .2. Instead of the sliding feet 1 1 .2, roller elements can also be used. If the seat is now loaded, especially if a user sits on the seat 31 or the additional seat 35, a force F in the

Foot 1 1 introduced. This causes the slide foot 1 1 .2 to be moved against the spring preload. Then the stopper 1 1 .5 sits on the floor and prevents the seat from being moved.
