DESCRIPTION OF EMBODIMENTS

In the Fig. 1 to 7 a seat device 1 according to the invention is shown, wherein the seat device 1 is shown in a folded-up position or starting position. The Fig. 1 and 2 show the seat device 1 with an additional backrest 2 in a perspective view and a side view. In the Fig. 3 to 7 the backrest is left out. Fig. 3 shows the seat device 1 in one Top view, Fig. 4 the seat device 1 in a side view and Fig. 5 the seat device 1 in a perspective view from below. Fig. 6 shows the seat device 1 again in a front view and Fig. 7 the seat device 1 in a rear view.

The seat device 1 according to the invention has a seat 3, on both sides of each of which an additional pivotable seat element 4 is provided.

The in the Fig. 1 to 7 and subsequent ones 8 to 18 Seating device 1 shown is formed, for example, as an office chair 5, which on chair rollers 8, as in the following Fig. 15 is indicated, is mounted rollable and is optionally rotatable about its axis. The office chair 5 has the backrest 2 and optional additional armrests. In this case, the seat device 1 according to the invention may optionally be formed with a backrest height adjustment device and / or a backrest tilt adjustment device 26 for changing the height and inclination of the backrest 2, if such a backrest 2 is provided. In eg the following Fig. 15, 16 and 18 By adjusting the backrest height adjustment device 24 and an associated backrest height adjustment lever 25 for the backrest 2, as in following Fig. 15, 16 and 17 and the seat reclining lever 27 of the recliner recliner 26, the height and inclination of the recliner 2 can be adjusted as needed.

The same applies to a seat tilt adjustment or a seat ball-like, i. horizontally rocking and / or swinging around the seat, the seat of the seat 3 and the associated seat elements 4. Such a tilt adjustment of the seat 3 is made e.g. by a corresponding seat tilt adjustment device 30 with an associated seat tilt adjustment lever 31 which actuates a seat tilt mechanism of the seat tilt adjustment device 30.

The in the Fig. 1-14 shown seat device 1, for example, an additional seat height adjustment device 28, for example, a gas spring, etc., with the addition of the seat height of the seat device 1 can be adjusted. The adjustment of the height of the chair or seat 3 by the seat height adjustment 28 takes place by pressing the example in the following Fig. 15-18 shown seat height adjustment lever 29 of the seat height adjustment 28th

In this case, the chair mechanism with the seat 3 and its seat elements 4 and, if present, the backrest 2 and possibly additional armrests, not shown, supports on the upper end of the seat height adjustment device 28.

The seat device according to the invention can be designed with a backrest and optionally additional armrests, for example as an office chair, etc., or without a backrest and armrests as a stool. The stool can also be designed to be rollable.

The respective seat element 4 is, for example, articulated to the seat element 3 in such a way that it is pivoted between a pivoted-up position or a starting position and a swung-down position Position or end position is pivotable, in which the seat device 1 provides a kind of saddle or saddle seat. In the starting position, the seat 3 with the two seat elements 4 forms a common continuous or substantially continuous seat surface. The plane formed by the seat 3 and the plane formed by the seat elements 4 lie, for example, at the same or substantially the same height as, for example, in the front and rear view of the seat device 1 in FIGS Fig. 6 and 7 is shown and in Fig. 6 is indicated by a dashed line. It is also conceivable that the seat elements 4, for example, are slightly swung over the seat 4 and its seat and form a kind of U-shape or arch with the seat 3.

In the lowered position or end position, the two seat elements 4 are pivoted or folded downwards relative to the seat 3 and form with this a saddle seat or saddle shape. The plane formed by the seat elements 4 extends at an angle or obliquely to the plane of the seat 3 such as in the following FIGS. 13 and 14 is indicated by a dashed line.

So far, saddle chairs are still a shadowy existence, because they look a bit strange at first and because some users may not want to sit on such a saddle chair all the time.

The "saddle sitting", which is provided by such a saddle chair, has the advantage over normal chairs, that it prevents a jam on prolonged sitting.

Due to the seat device 1 according to the invention, a saddle sitting as well as a normal sitting can now be made possible both when needed. In this way, a user can thus enjoy temporarily or at will the merits of a saddle chair, without having to do without a normal seat completely.

In this case, the respective seat element 4 of the seat device 1 according to the invention can be locked at least in the pivoted-up starting position as well as in the downwardly pivoted end position. In a further embodiment of the seat device 1 according to the invention, at least one of the seat elements 4 can additionally be provided lockable in different intermediate positions between the starting and the end positions. As described above, the Fig. 1 to 7 and the following ones Fig. 15-18 , the raised position or starting position of the seat device according to the invention 1. The following 8 to 14 again show an example of the lowered position or end position of the seat device according to the invention. The invention is based on the degree of heruntergeschtten or folded down seat elements 4, as in the 8 to 14 shown, not limited. The illustration is only an example. It is also conceivable that the seat elements 4 can be swung down by up to 90 ° relative to the seat 3 and its plane, depending on the function and purpose.

The respective seat element 4 is connected to the seat 3, for example by means of at least one hinge 9, or at least two hinges 9 as in Fig. 5 is shown as an example, pivotally or hingedly connected.

Furthermore, the seat device 1 has a pivoting device 10 for pivoting the seat element 4 relative to the seat 3 between the pivoted-up starting position and the lowered end position.

That in the Fig. 1 to 7 and subsequent ones 8 to 18 shown embodiment of the pivoting device 10 has, for example, a rotatable disc 11, which is arranged below the seat 3, for example on a connecting element 12, which connects the seat height adjustment device 28 and the seat 3. The disk 11 is arranged, for example, in alignment with the seat height adjustment device 28.

A first end 13 of a rod member 14 is rotatably mounted on the rotatably mounted disc 11, for example on the end face of the rotatably mounted disc 11. The other second end 15 of the rod member 14 is in turn rotatably mounted on the underside of the seat member 4. For this purpose, the second end 15 of the rod member 14 is rotatably mounted by means of a holder on the underside of the seat member 4. The second end 15 is formed for example as an eyelet, through which a shaft or a shaft portion of a screw element can be passed.

The attached to the disc 11 first ends 13 of the two rod members 14 are, for example, rotatably mounted on the front side of the disc 11 such that the two first ends 13 and the center 16 of the disc 11 lie on a common horizontal or horizontal axis, as in Fig. 5 is indicated with a dotted line when the seat elements are pivoted to the raised position or home position.

The first ends 13 of the two rod elements 14 are attached to the disc 11, e.g. screwed by a suitable screw member 16 each and rotatable about the longitudinal axis of the associated screw member 16. Such a rotatable attachment is particularly easy and inexpensive to implement. However, the invention is not limited to this attachment nor to the attachment to the end face of the disc 11. In principle, for example, an attachment to the circumference of the disc 11, etc. possible.

For pivoting the seat elements 4 relative to the seat 3 in the end position, as in the following 8 to 14 is shown, for example, a seat member actuator 7 is provided with a knob 18 by means of the disc 11 is rotated and thereby adjusted via the rod members 14 connected to the disc 11 seat elements 4 and then locked in the set position.

The knob 18 is coupled to the disc 11 so that the knob 18 in a locked position, the disc 11 is locked so that rotation or further rotation of the disc 11 is prevented. In one embodiment, as in the Fig. 2 . 17 and 18 is shown, the knob 18 can be held or positioned by means of a spring element 6 in the locking position as a starting position.

If the knob 18 is actuated, for example, pulled forward as in Fig. 4 is indicated by an arrow, the knob 18 is moved from its locking position to an actuating position, in which by means of additional Turning the knob 18, the disc 11 can be operated or rotated to adjust the connected via the rod members 14 with the disc 11 seat elements 4. As soon as the disk 11 has been rotated sufficiently clockwise or counterclockwise by means of the actuated, ie pulled forward, rotary knob 18 and the seat elements 4 have been pivoted into a desired position, the rotary knob 18 can be released and is moved back into its locking position by the spring element 6 or withdrawn, in which the disc 11 is locked by the knob 18 and can not be further rotated.

In this way, the seat member actuator 7 pivot by its knob 18, the seat elements 4 by turning the disc 11 by means of the knob 18 not only between the pivoted up position and the swung-down end position, but also lock in the respective pivoted position. In one embodiment of the seat device 1 according to the invention, at least one of the seat elements 4 can additionally be locked in different intermediate positions between the initial and the end position by the seat element actuating device 7 and its rotary knob 18. As described above, the knob 18 for locking the seat elements 4 in the desired position by the spring element 6 simply moved back to its locking position, for example, be withdrawn. To release the locking and pivoting of the seat elements 4, the knob 18 is simply pulled back against the force of the spring element 6 forward and additionally rotated in or counterclockwise until the desired position of the seat elements 4 is reached, such as in the Fig. 4 . 6 . 8th and 13 indicated by a double arrow. This has the advantage that the knob 18 both to Actuate the disc 11 and thus pivoting the seat elements 4 and for locking the seat elements 4 can be used in the desired position. As a result, a particularly simple and cost-effective actuating device can be provided and an additional separate locking device can be dispensed with. However, the invention is not limited to this embodiment of an actuator with a knob. Any form of actuating device can be provided which is suitable at least for rotating the disk 11 and thus pivoting the seat elements 4 connected to the disk 11. Preferably, the actuator may additionally be designed as a locking device and lock the disc 11 in a rotated position and thus the seat elements 4 in a pivoted position, so that they can not move accidentally. Likewise, a separate locking device can be provided which can lock the seat elements 4 in a pivoted position.

In Fig. 4 is the movement of the turret forward for releasing the locking of the disc 11 indicated by an arrow. The rotation of the disc 11 by turning the knob 18 is in Fig. 4 . 6 and 8th again indicated by a double arrow. The pivoting of the seat elements 4 is in Fig. 6 and 8th indicated by arrows accordingly. Will, as in Fig. 6 is indicated, the disc 11 is released or released by the knob 18 to rotate, so the disc 11 can be rotated, for example by the knob 18 counterclockwise and thereby_ the respective seat element 4, which is connected via the respective rod member 14 with the write 11 like with an arrow in Fig. 6 is hinted to be swung down. The seat member 4 pivots down to the desired intermediate position or End position, as in the following 8 to 14 is shown. At the same time the other seat member 4, which is also rotatably connected via its rod member 14 with the disc 11, thereby pivoted down into the desired intermediate position or end position by rotating the disc 11, as in the following Fig. 12 . 13 and 14 is shown.

For locking the seat elements 4 in a respective desired position, including the starting, the end or an intermediate position, the knob 18 is simply released and moved back or retracted by means of the spring element 6 in the starting or locking position.

As in the embodiment in the Fig. 1-14 is shown, the respective rod member 14 is for example made in two parts and has a first and second rod member part 19, 20. The first rod member part 19 has the first end 13 of the rod member 14 and is rotatably screwed, for example, with the first end 13 on the end face of the disc 11, as described above. The second rod member part 20 in turn has the second end 15 of the rod member 14 which is rotatably attached to the underside of the seat member 4. For this purpose, the second rod element part 20 has a through hole, for example a bore, through which, for example, a screw bolt 23 can be passed. The second rod member part 20 is disposed between two legs 21 of a U-shaped carrier 22 and rotatably secured by the bolt 23 thereto. The U-shaped support 22 is in turn attached to the underside of the seat member 4, for example screwed. However, the invention is directed to this particular rotatable attachment of the second end 15 of the rod member 14 by means of a carrier and in particular U-shaped support 22 and a bolt 23 is not limited. Any attachment suitable for rotatably fixing the rod member 14 to the seat member 4 may be provided so that the seat member 4 can be swung up and down.

The first rod element part 19 is connected to the second rod element part 20, for example by screwing. The first rod element part 19 can be screwed into the second rod element part 20, as in the embodiment in FIG Fig. 5 is shown, or as not shown externally screwed on it. Conversely, the second rod member part 20 can be screwed into the first rod member part 19 or be screwed onto this. By this two-part design of the rod member 14 and the screw connection of the two rod member parts 19, 20, the total length of the rod member 14 can be easily adjusted and adjusted as needed. However, the rod element 14 may also have any other suitable at least two-part design. Furthermore, the rod member 14 may also be integrally formed, for example, as an elongated rod or rod. This is particularly inexpensive to manufacture and easy to assemble.

The pivoting device 10, as in the Fig. 1 to 14 is shown, from a disc 11 and two rod elements 14, and an actuator 7 with its knob 18 and the spring element 6, which is additionally designed as a locking device, have the advantage that they are easy to implement and assemble, as well as inexpensive to manufacture are.

However, the invention is not limited to this embodiment of the pivoting device 10. Likewise, the respective seat element 4 may be provided by means of each pivoting device, which is suitable for pivoting the seat elements 4 up and down. Such a pivoting device for pivoting the seat elements 4 may be, for example, mechanically, e.g. by means of a telescopic connection, hydraulically, electromechanically and / or pneumatically, etc. The same applies to the actuating device and the locking device, which may be a separate part or alternatively part of the actuating device. Such an actuating device and / or locking device can be designed both mechanically, as described above by way of example, and electrically, electromechanically, hydraulically, and / or pneumatically actuated.

As in particular in the plan view and the side view of the seat device 1 in 3 and 4 is shown, the seat 3 forms with its seat elements 4 in the starting position a common continuous or substantially continuous seat. For example, the seat may have a triangular section with the apex of the triangle facing forward. The two seat elements 4 are hinged up and down on each of two sides of the triangular section. The seat elements 4 have, for example, a quadrangular shape or trapezoidal shape, as in Fig. 3 shown. Any other form of seating elements 4 suitable for the seating device 1 is also possible. The same applies to the seat 3.

In the 8 to 14 the seat device 1 according to the invention is shown in the lowered position or end position. The Fig. 8 and 9 show the seat device 1 with the additional backrest 2 in a perspective view and a side view. In the 10 to 14 the backrest is left out.

Accordingly, the first end 13 of the other rod member 14 is rotated on the disc 11 upwards. In the in Fig. 12 shown position or end position of the seat elements 4 are the first end 13 of a rod member 14, for example in the lowest position on the disc 11 and the first end 13 of the other rod member 14 at eg the highest position on the disc 11. The seat elements 4 can This position can be additionally locked by the actuator 7 and its knob 18. For this purpose, the knob 18 only needs to be released. By the spring element 6, the knob 18 automatically moves to its initial or Arreterierungsposition.

As described above, this downwardly pivoted position of the seat members 4, in which they together with the seat 1 form a saddle seat, has the advantage that a venous jam can be prevented.

To pivot the seat elements 4 back up to the starting position, the actuator 7 is actuated with its knob 18, for example, pulled forward against the force of the spring element 6 described above, and the seat elements 4 of the seat device 1 thereby moves upwards by the user by additionally turning the knob 18, as with an arrow in Fig. 13 is indicated, clockwise.

In this case, the disc 11 rotates clockwise in accordance with and with it the first ends 13 of the two rod elements 14 to the seat member 4, for example, again the raised position or starting position in Fig. 5 reached. In this position, the seat elements 4 can also be locked by the actuator 7 and its knob 18 by the user simply let the knob 18.

In this way, a user can comfortably switch between normal sitting and saddle seating as he wishes and take full advantage of the comfort of both seat shapes.
