The medial supports 23 and the second partial lever arms 1 13 of the lever arms 109 are arranged adjacent to each other.

About the lever arms 109, the part seats 101 and 103 each associated with a Schwenklagerfedervorrichtung 115.

By means of a first arrow 117, a longitudinal direction of the seat device 1 is indicated in FIG. 1. By means of a second arrow 119, a transverse direction of the seat device 1 is indicated in FIG. By means of the pivot bearing spring device 115, the lever arms 109 and the associated part seats 101 and 103 are pivotally mounted, namely with a first spring stiffness about a first longitudinally extending pivot axis and with a second spring stiffness about a second extending in the transverse direction

Pivot axis. To enable the different spring stiffnesses, each of the lever arms 109 is assigned a first elastic bearing 121 and a second elastic bearing 123. The elastic bearings 121 and 123 can be designed as a rubber bearing. However, it is also conceivable to provide coil springs instead of the rubber bearings. The first elastic bearing 121 may include a lateral base buffer 25. The second elastic bearing 123 may include a medial base buffer 27, with the medial base buffers of the respective partial seats 101 and 103 adjacent to each other.

The elastic bearings 121 and 123 are seen in the direction of the arrow 119, ie in the transverse direction of the seat device 1 next to each other, arranged. As a result, it can be effected that the second pivot axis extends through the juxtaposed elastic bearings 121 and 123. The first pivot axis along the direction of the first arrow 1 17, ie in the longitudinal direction, passes between the elastic bearings 121 and 123 therethrough. It can be seen that this results in different spring stiffness, wherein a pivoting movement about the second pivot axis, which corresponds to a forward and rear rockers of the person or the part seats 101 and 103, a lower spring stiffness of the elastic bearings 121 and 123 counteracts as a pivoting movement about the first pivot axis. A pivoting movement of the partial seats 101 and 103 or the associated lever arms 109 corresponds to a right and left rockers of a seated on the seat device 1 person. Advantageously, the rocker can be limited to the right and left with the higher spring stiffness, which allows the seated person while this degree of freedom, but gives a comparatively high security or a corresponding sense of security or mediates.

The partial lever arms 11 1 and 113 are each angled and have at their, in the orientation of FIG. 1, facing down ends bearing receivers 125 for the elastic bearings 121 and 123.

Corresponding abutments are formed by means of base plates 29 which are respectively associated with the first elastic bearing 121 and the second elastic bearing 123 for receiving or transmitting the bearing forces. The base plate 29 of the first partial seat 101 and the base plate 29 of the second partial seat 103 are assigned to a common connecting plate 31. The connecting plate extends in the direction of the second arrow 119, that is in the transverse direction of the seat device 1. For mounting the seat device 1 on a substrate, not shown, for example, a floor, the connecting plate 31 is approximately centrally associated with a chair leg 33 with a total of five bearing surfaces. The assignment of the connecting plate 31 to the chair leg 33 may alternatively and / or additionally be effected by means of a rotatable spring damper device, for example a gas spring 127, the seat device 1 having the functionality of a swivel chair. The gas spring 127 can be operated by means of an operating lever 129, for example for realizing a height adjustment by means of opening and closing a non-illustrated overflow valve of the gas spring 127th

FIG. 2 shows a rear view of the seat device 1 shown in FIG. 1. FIG. 3 shows a side view of the seat device 1 shown in FIGS. 1 and 2. Reference will now be made to FIGS. 1-3. The base plates 29 of the partial seats 101 and 103 are associated with the connecting plate 31 each by means of a pivot bearing 35. The pivot bearing 35 can be designed as a swivel bearing, ie without the use of rolling bearing devices. By means of the pivot bearing 35, the partial seats 101 and 103 are each rotatable about an axis of rotation 39 drawn by way of example on the left in FIG. 2. To inhibit a corresponding rotational movement about the axis of rotation 39, a braking mechanism 37 is provided per partial seat 101, 103. The brake mechanism 37 may be adjustable by means of an adjusting screw 71, for example by setting a corresponding coefficient of friction between the brake mechanism 37 and a braking surface 131 of the connecting plate 31. It is conceivable to perform the braking surface 131 circularly curved, wherein during a rotational movement of the part seats 101 and 103 around the respective axis of rotation 39 results in a constant braking force. However, it is alternatively and / or additionally also conceivable to execute the braking surfaces 131 of a circular shape deviating form, wherein it is possible, for example, to allow a progressive braking effect, for example at correspondingly larger angles of rotation about a neutral position of the part seats 101 and 103rd

To the right of the axis of rotation 39, a support center 41 of the part seats 101 and 103 is shown. The support center axis 41 can be understood as the line of action of seat bumps of a person sitting on the seat device 1 become. It can be seen that the support center axis 41 is arranged at a distance from the axis of rotation 39 and lies further inwardly with respect to the seat device 1. Furthermore, it can be seen in FIG. 2 that the support center axis 41 is arranged axially symmetrical to the suspension 105 or 107, resulting in a tilting moment of the respective seat shells 3 and 5 when the person sits down or sits down. For the first seat shell 3, shown on the left in FIG. 2, the tilting moment acts in the direction of a third arrow 133 and for the second seat shell 5, shown on the right in FIG. 2, in the direction of a fourth arrow 135. To support this tilting moment are the medial Buffer mechanisms 15, 17 each dimensioned smaller than the lateral buffer mechanisms 9, 11th

Advantageously, a person seated on the seat shells 3 and 5 of the seat device 1 must therefore carry out a compensating movement against the tilting moments symbolized by the arrows 133 and 135, which is advantageously no longer consciously perceived after a short sitting time, but decisively contributes to a particularly comfortable sitting feeling.

By means of the rotatably mounted gas spring 127, the part seats 101, 103, which are associated with the connecting plate 31, are rotated relative to the chair leg 33 about a drawn in Fig. 2 center axis 43 of the seat device 1.

In the side view of Fig. 3 are to illustrate the arrangement of the partial elastic bearings of the buffer mechanisms 9, 11, 15, 17 axes 45 - 51 located. The axles 45 - 51 may be, for example, longitudinal axes corresponding to rubber bearings of the partial elastic bearings of the suspension 105 or 107 which are not located in an image plane of FIG. In Fig. 3, the first suspension 105 is visible, wherein a lateral anterior buffer 9 a lateral anterior longitudinal axis 45, a lateral posterior buffer mechanism 11 a lateral posterior longitudinal axis 47, a medial anterior buffer mechanism 15 medial anterior longitudinal axis and a medial posterior buffer mechanism 17 a has medial posterior longitudinal axis. It can be seen that the longitudinal axes 51 and 49 have a smaller distance than the longitudinal axes 47 and 45. In addition, the longitudinal axes 51 and 49 lie between the longitudinal axes 47 and 45. The longitudinal axes 45 - 51 shown in FIG. 3 are The longitudinal axes 45 - 51 are at a spatial angle to each other and run, seen in an orientation of Fig. 1-3 - down apart. It is conceivable that the longitudinal axes 49 and 51 of the medial Buffer mechanisms 15 and 17 coincide with only one of the buffer mechanisms is provided, so that the buffer mechanisms 9, 11 and 15 are arranged triangular.

The partial elastic bearings or the buffer mechanisms 9, 11, 15, 17 is assigned a rail 53 for transmitting the bearing forces, which has a bearing receptacle 137 per partial elastic bearing or buffer mechanism 9, 11, 15, 17. The rail 53 can be assigned to the partial lever arms 111 and 1 13 of the lever arms 109 by means of holes 55 and a bolt 57 passing through the holes. For this purpose, the rail 53 may have a T-shaped cross section, wherein a downwardly facing centrally disposed rib of the T-shaped cross section between the partial lever arms 111 and 113 can be arranged and fixed by means of the holes 55 and the bolt 57. To secure the bolt 57, a split pin 59 may be provided.

By means of a screw 61, an inclination can be set along the longitudinal direction of the seat shells 3 and 5 of the part seats 101 and 103 symbolized by the first arrow 117. For this purpose, the rail 53 may be pivotably mounted about the bolt 57, wherein for adjusting the inclination or the basic angle, the downwardly projecting rib of the rail 53 frictionally and / or non-positively between the partial lever arms 111 and 1 13 is fixable. For this purpose, the partial lever arms 111 and 1 13 can be pulled together by means of the screw 61 until they abut frictionally and / or non-positively on the rib of the rail 53.

The partial lever arms 1 1 1 and 113 have a plurality of holes 63, in which the screw 61 can be introduced. For presetting the inclination, the screw 61 can optionally be introduced into one of the holes 63, wherein the screw 61 initially forms a stop for the pivotal movement of the rail 53 about the pin 57. For each of the holes 63 results in striking the rail 53 to the screw 61, a different inclination of the seat shells 3, 5 of the part seats 101, 103. In the abutting position of the above-described force and / or frictional engagement by tightening the screw 61st getting produced.

For limiting a rotational angle of the pivot bearing 35 bolts 65 may be provided which can be inserted into holes 67 of the connecting plate 31. For this purpose, the connecting plate 31 may have a multiplicity of holes 67 lying on a radius into which, depending on the desired pivoting angle of the partial seats 101 and 103, about the pivoting axis 39 a corresponding pin 65 can be inserted. To limit the angle of rotation, the base plates 29 each have a protrusion 69, which form a cooperating with the bolt 67 stop to limit the pivoting angle.

For fixing the rail 53 to the partial levers 111 and 1 13, these holes 73 may have, through which the bolt 57 engages.

4 shows a rear view of a further seat device 1. According to a partial aspect of the invention, as can be seen from FIG. 4, the pivot bearing devices 115, the pivot bearings 35 and the lever arms 109 are dispensed with. Advantageously, the seat shells 3 and 5 are assigned directly to the connecting plate 31 by means of the suspensions 105 and 107. As a further difference, the bottom plate 19 of the suspensions 105 and 107 has no rail 53 or no T-shaped cross-section and is directly assigned to the connecting plate or can be attached to it.

FIG. 5 shows a further rear view of a seat device 1. According to a further partial aspect of the invention, the pivot bearing 35 and the associated brake mechanism 37 can still be provided per partial seat 101 and 103 in comparison to the representation of FIG. Optionally, analogous to the representation of FIGS. 1-3, a limitation of the pivoting angle by means of the bolts 65, the holes 67 and the

Protrusion 69 of the base plate 29 may be provided.

6 shows a detailed view of a suspension 105 analogous to the suspension 105 shown in FIG. 1. Shown is a detailed view of one of the partial elastic bearings, which is embodied as a partial seat spring leg 139 according to a further partial aspect of the invention. The Teilsitzfederbein 139 is shown in Fig. 6 in a total of three different positions.

The Teilsitzfederbein 139 has a spring rod 141 with an upper spring stop 143 and a lower spring stop 145. The spring stops 143 and 145 are either associated with or part of the spring bar 141. Furthermore, the Teilsitzfederbein 139 has a central spring stop 147. The middle spring stop 147 acts on both sides, between the upper spring stop 143 and the middle spring stop 147, an upper elastic spring 149 and between the middle spring stop 147 and the lower spring stop 145, a lower elastic spring 151 are arranged. The elastic springs 149 and 151 may be, for example, material springs, for example elastomer springs and / or rubber springs. However, it is also conceivable to use these as coil springs, which can be loaded under pressure.

The elastic springs 149 and 151 have an opening, for example a central bore, in which the spring rod 141 is arranged to guide the elastic springs 149 and 151. It can be seen that the middle spring stop 147 also has an opening, for example a hole through which the spring rod 141 engages. The central spring stop 147 is thus displaceably mounted along a longitudinal direction of the Teilsitzfederbeins 139, which is symbolized in Fig. 6 by means of a fifth arrow 153, back and forth.

For introducing bearing forces into the partial seat spring leg 139, either the middle spring stop 147 and the upper spring stop 143 or the middle spring stop 147 and the lower spring stop 145 or all three spring stops can serve together.

According to the representation of FIG. 6, the lateral connecting plate 7 is assigned to the upper spring stop 143 or has this on. The bottom plate 19 has the middle spring stop 147 or is assigned to this. It can be seen that the partial seat spring strut has an identical characteristic with an assumed identical design of the elastic springs 149 and 151 on push and pull. Accordingly, only a deformation of the upper elastic spring 149 takes place, which is symbolized in a middle view of FIG. 6 or a deformation of the lower elastic spring 151, which is shown in a lower illustration of FIG. In an upper view of FIG. 6, a neutral position of the Teilsitzfederbeins 139 is shown, wherein the central spring stop 147 is located centrally between the other spring stops 143 and 145.

Alternatively and / or additionally, it is conceivable that the middle spring stop 147 is guided or mounted in a wobble-like manner on the spring rod 141. Advantageously, this results in a further storage of the central spring stop 147 according to the wobble, further rotational degrees of freedom.

The upper spring stop 143 is assigned by means of the connecting plate 7 of the corresponding associated seat shell 3, 5 of the corresponding part seat 101, 103. Of the middle spring stop 147 is assigned by means of the bottom plate 19 of the rest of the seat device 1, in particular the connecting plate 31 and / or the base plate 29 and / or the Schwenklagerfedervorrichtung 1 15 and / or the Teilhebelarmen 1 11, 113 one of the lever arms 109.

7 shows a detail view of a tilt adjuster 155 for adjusting a longitudinal inclination of the seat shells 3 and 5 of the split seats 101 and 103. In one aspect of the invention, the tilt adjuster 155 has an eccentric 157. Evident are the lateral support 21 of the first Teilhebelarms 1 11 and the medial support 23 of the second Teilhebelarms 1 13, between which the rail 53 engages. The inclination adjusting device has the above-described holes 55, into which the bolt 57 for forming a pivot bearing for the rail 53 can engage.

In contrast, according to the sub-aspect of the invention, instead of the plurality of holes 63 only a single hole 63 is provided, into which the screw 61 can engage. Alternatively and / or additionally, the screw 61 may be formed only as a bearing pin. The eccentric 157 is rotatably supported by means of the screw 63 passing through the hole 63. In the present case, the eccentric 157 is designed as an eccentric polygon, for example as a quadrangle, wherein the screw 61 is arranged so eccentrically that it has different distances to side surfaces 159 of the eccentric polygon 165.

By way of example, FIG. 8 shows three different settings of the inclination adjustment device 155, one of the side surfaces 159 abutting or abutting flat against a stop surface 161 of the rail 53. It can be seen that, due to the different distances of an acentric bore 163 of the eccentric 157, different inclinations of the rail 53 can be set. Alternatively and / or additionally, it is conceivable that the rail 53, which forms a pivoting arm and / or the eccentric 157 are blocked, for example by means of the screw 61 and / or by means of another screw, as a substitute for the bolt 57. To perform the Bolts 57 have the rail 53 and the partial lever arms 11 1 and 1 13 corresponding holes 73 and holes.

9 shows a partial rear view of a first part seat 101 of a seat device 1 analogous to the seat device 1 of FIGS. 1 to 3. According to a further partial aspect of the invention, FIG. In order to limit the pivotal movement of the first part seat 101, a stop plate 167 is provided around the second pivot axis indicated by the second arrow 119. The stop plate 167 acts as a limiter for the pivoting movements about the second pivot axis.

FIGS. 10 to 12 each show different aspects of the invention, in each case embodiments of the stop plate 167 shown in a side view. As can be seen in FIGS. 10 to 12, the stop plate 167 is fixed, in particular rotationally fixed to the supports 21, 23 or the partial lever arms 111 , 113 of the lever arm 109 assigned. For this purpose, both the lever arm 109 and the stop plate 167 bores 169, for example, have two juxtaposed holes 169 through which can engage the fixing plate 167 corresponding fixing means, such as screws, bolts, rivets and / or the like. For limiting the pivoting movement in a first direction, which is indicated in Fig. 10 by means of a sixth arrow 171, the stop plate 167 has a first stop 173. The first stop 173 cooperates with the base plate 29 or can abut on this to limit the pivoting movement. The stop plate 167 is wedge-shaped and has a wedge tip 175 which forms an acute angle to the rest of the stop plate 167 with the first stop 173. The wedge tip 175 is disposed at a distance 177 to the base plate 29, wherein Fig. 10 shows the seat device 1 in an unloaded state. In a loaded state, that is, when a person has taken place on the first part seat 101, the distance 177 may decrease, in particular reduce so far that the wedge tip 175 is in abutting contact with the base plate 29. In this case, the stop plate 177 form a movable bearing with the wedge tip 175, wherein the wedge tip 175 is mounted back and forth relative to the base plate and the wedge tip 175 a rocker or the second pivot axis or parallel to the second pivot axis extending

Pivoting axis represents. It can be seen that in the case of a deflection of the first partial seat 101 in the direction of the sixth arrow 171, this can be limited by means of the first stop 173, whereby the first stop 173 abuts against the base plate 29.

FIG. 11 shows, according to a further partial aspect of the invention, a side view of a further stop plate 167 which, in contrast to the representation of FIG. 10, has a second stop 179 arranged essentially in mirror image. By means of the second stop 179, the pivoting movement about the second pivot axis in a second direction, which is symbolized in Fig. 11 by means of a seventh arrow 181, are limited. With regard to the function of the second stop 179, reference is made to the description of FIG. 10.

FIG. 12 shows, according to a further partial aspect of the invention, a side view of a stop plate 167 which, in contrast to the illustration according to FIGS. 10 and 11, has a first stop 173 and a second stop 179. In contrast, the first stop 173 and the second stop 179 are arranged on the right and left of the wedge tip 175 at an obtuse angle. It can be seen that the first stop 173 and the second stop 179 have different angles to a surface of the base plate 29 in the rest position of the seat device 1 shown in FIG. 12. Corresponding to the different angles, a differently wide deflection of the first part seat 101 can take place in the first direction 171 symbolized by means of the sixth arrow and in the second direction symbolized by means of the seventh arrow 181.

With regard to the function of the stops 173 and 179, reference is made to FIGS. 10 and 11.

FIG. 13 shows a side view of another seat device 1 similar to the seat device 1 shown in FIG. 5. In contrast, the seat device 1 of FIG. 13 has a backrest 75 and a headrest 77. The backrest 75 and the headrest 77 are pivotally associated by means of a base joint 79 of the connecting plate 31. The base joint 79 is associated with a base spine 83 by means of a base connector 81. The spine link 83 supports a spine connector 85 pivotally relative to the base connector 81. The spine connector 75 is associated with the backrest 75 and the headrest 77. The backrest 75 is pivotally associated with the back section connector by means of a backrest hinge 87. The headrest 77 is pivotally associated with a headrest connector 89 by means of a headrest hinge 91 with the headrest connector 89 disposed between the headrest hinge 91 and the backrest hinge 87.

FIG. 14 shows, according to a further partial aspect of the invention, a further seat device 1 analogous to the seat device 1 shown in FIG. 13. In contrast, the seat device 1 additionally has an armrest 93. The armrest 93 is by means of a Armrest joint 95 an armrest support 97 assigned.
