Description
~Z~ 57 B KGROUND OF THE INVENTION
Technical Field The present invention relates to an arrangement for the adjustment of an object. Such arrangement is particularly, but not exclusively, applicable to the adjustment of a vehicle seat in at least two directions of movement, such as vertically and longitudinally.
Prior Art D~-PS 2 952 030 issued 26 November 1981 to Audi NSU
Auto Union AG, shows an arrangement of this type with an actuating device by means of which it is possible to control the drive of driving elements associated with each different direction of movement. The actuating device has a control member and a pivoting arm which are in active connection through a sliding guide. This actuating device comprises a drivable sun wheel and at least one planet wheel which can be moved by the control member in such a manner that it is selectively engageable with each driving element, thereby permitting various directions of move-ment of the object. The driving elements are in the form of drive wheels or toothed wheels. The planet wheel and the driving elements have an external toothing with an amount of play of a maximum of one tooth gap. Connected with the control member are two pivotable arms which, by means of at least two planet wheels, permit the simultaneous drive of different driving 1;2~845~
elements~ The sun wheel in this arrangement is designed as a flat disc o~ comparatively large diameter, on the circumference of which each externally toothed driving element is disposed.
drive plnion engages with each driving element and is connected with a drive motor. Tn~ sliding guide is incorporated into the control member. Pins firmly connected with each pivoting arm engage with said slidlng gui~e.
This known device is too bulky to be suitable for the vertical and longitudinal adjustment of vehicle seats wherer as is well known, only limited space is available~ Alsor it is difficult to dPsign the slidlng guiae so exactly that a non-forciny engagement of the planet wheels wi~h tne external toothed wheel of the sun wheel and therefore also with the associated drive wheels is ensured.
The object of the inven~ion is therefore to simplify this known arrangement constructionally and to ensure a non for~ing engagement of t~e planet wheels with the toothing of the sun wheel or the drive wheelsO
The present invention provides an adjusting arrangement for controlling the movement of an object ~2~ t~
in at leas~ two directions~ the object having at least one toothed driving element associated with each direction of movement, the arrangement including a control member having an eccentric, a drivable internally toothed sun wheelr and at least one toothed planet wheel movable by means of said control member in such a manner that it is selectively engageable with each said toothed driving element to cause motion of the o~ject in each different direction, the control member eccentric being rotatably mounted in said planet wheelO

Figure 7 is an isvmetric ~epresentation of a motor vehicle seat frame wi~h tne arrangement incorporated ~2~ 5~
therein; and Figure 8 is an isometric representation of a motor vehicle seat frame with a modified arrangement incorporated therein.
Reference numeral 1 deno~es a sun wheel which can be driven by means of a pole-changeable motor not represented further in tne drawing. Tne sun wheel 1 has internal toothing 2 and is in the shape of a vessel defining a cavity with a bottom portion and a side wall carrying the internal toothing 2.
Connected wi~h tne sun wheel 1 is an axle 3 which is connected with a hand wheel 4, so that the arrangement can be driven either by tne drive motor (not shown) or by hand.
There is also provided at least one planet wheel 5.
Tne external toothing ~ o~ this planet wheel engages with the internal toothing 2 of the sun wheel~ The pitch diameter d of the external toothing 6 of ~he planet wheel 5 is smaller than the pi~ch diameter ~ of the internal toothing 2 of the sun wheel 1. The planet wheel S thus engages within the sun wheel 1 t as a result of which an outstandingly compact, space-12~ ;7 saving arrangement is ensured which for the first timeopens up tne possibility of disposing this arrangement in a motor vehicle seat where space conditions are extremely limited.
Tne tooth width ~ of the external toothing 6 of the plane thwel 5 is greater than tne tooth width ~ of the internal toothing 2 of the sun wheel l.
The planet wheel 5 is movable by means of a control member in such a way that the planet wheel can be selectively engaged with any one of various driving elements allowing differen~ directions of movement of the object. In the present case tne driving elements are toothed wheels 7 to 10. The contro} member includes an eccentrie part ll and a centric part 12.
On the eccentric part ll of this eccentric arrangement 11,12 tne planet wheel 5 is rotatably mounted. It is clear ~hat the structure of the eccentric as well as the situatlon oE the individual toothed wheels 7 to 10 relative to the planet wheel 5 are so selected that in a particuldr setting position of the control member the desired engagement of thP teeth of the required toothed wheel 7 to 10 with tne teeth of tne plane~
wheel 5 or planet wheels is ef~ected. The man skilled in tlle art will appreciate how this selection may be lZ~1~457 performed for a specific case. The selection may be empirically determined.
Tne two parts 11,12 of the eccentric which forms the control member for the plane~ wheel 5 are rotatable by means of a setting lever 13 about a shaft 3. The centre line m-m of the shaft coincides with that of the driving axle 14 of the sun wheel. The setting lever 13 is guided in a setting slide 15 with several engagement positions~ Each engagement position is associated with at least one direction of movement of the objert~ The centric part 12 of the eccentric 11,12 is rota~ably mounted in tne setting slide 15 in bearings 16,17.
As ~igure 2 shows, the driving elements in ~he form of toothed wheels 7 to 10 are conne~ted with elastic shafts 18 to 21 by means of which the corresponding adjustment devices f~r tne vertical and longitudinal displacement of ~he vehicle seat can be ac~uated.
The operation of the described arrangement will now be explained in greater detail with reference to Figures 3 to 7. In this connection the position of the setting lever 13, a~ shown in ~hese Figures shoula ~e noted.
s~
I$ the motor (no~ shown) is set in motion it drives the sun wheel 1, the internal toothing 2 of which sets the plane~ wheel 5 in rotary motion by means of its external toothing 6. If the setting lever 13 assumes the engagement position represented in Figure 3 of the drawings, then tne toothed wheel 7 is in engagement with the planet wheel 5, while the toothed wheels 8 to are out of engagement. The ~oothed wheel 7 drives the elastic sha~t 18. As the toothed wheel 7 engages wi~h a toothed wheel 22 the two toothed wheels 7 and 22 ro~ate in opposite directionsL Toothed wheel 22 is connected by means of an elas~ic shaft 23 with an adjustment mechanism of the seat~ The corresponding rotary motion of elastic shafts 18 and 23 is transmitted to lif~ing devices 24,25 operating in the manner of screw drives onto tne frame 26 of the sea~ing area with the result that the latter is raised or lowered in accordance with the selected direction of rotation of the drive motor of the sun wheel 1.
The frame 26 of tne sitting area is mounted in a bearing 27~
In the representation according to Figure 4 the setting lever 13 assumes a different position represented therein. Toothed wheels 7 and 8 are in engagement wi~h planet wheel 5. The toothed wheel ~
~2~84S7 also drives toothed wheel 22. The wheel 8 drives elastic shaft 19 which is connected to a lifting device 28 on the front side of the frame 26 of the sitting area. The lifting devices 24,25 are driven by means of the elastic shafts 18,23. The frame 26 of tne sitting area is therefore raised or lowered in accordance with the direction of rotation of the drive motor of the sun wheel both at the fron~ and also at the rear.
In the representation according to Figure S only the toothed wheel 8 is in engagement with the planet wheel 5, so that on switching the driving motor of the sun wheel 1 the elastic shaf~ 19 is set in rotation and thereby the lifting device 28 is actuated. A lifting or a lowering of t~le front side of tne frame 26 of the sltting area is the result of this.
If the setting lever 13 is moved over to the position shown in Figure 6~ then only the toothed wheel 9 is in engagement with the planet wheel 5. ~oothed wheel 9 drives an elastic shaft 20 which in turn driYes a pini~n of a ra~k and pinion gear 29~3Q (~igO7). The toothed rack 30 of this rack and pinion geae 29,30 is connected with tne frame 26 of the ~itting area in such a manner tha~ in accordance with the direz~ion of i7 movement of the toothed rack 30 the vehicle seat is moved in the direction of vehicle tr2vel or in the opposite dlrection. For this purpose the frame 26 of tne sitting area is mounted in bearings 31 to 33.
The embodiment according to Figure 8 differ~ from that shown in Figures 1 to 7 essPntially in that the central axis of the arrangement and therefore of the sun wheel 1 extends approximately perpendicularly to the sltting level of the sltting area of the vehicle sea~. The setting lever 13 then assumes the position shown. In this arrangement the sun wheel 1 can be driven by mean~ of a toothed pinion 3~ which engages with a toothed crown of the sun wheel 1. In this sun wheelr for example, tnree planet wheels are disposed, the external toothed rims of which engage into ~he internal toothed rim of sun wheel 1. By means of the corresponding connection of the Pccentric connected with the setting lever 13 and bearing the planet wheels, it is possible to drive corresponding toothed wheels~ These toothed wheels also have internal ~oothed rims with which lead screws of the corresponding adjustment devices of the seat engage.
I~ is possible to provide, in addition to the internal toothing of tne toothed wheel 1, a further internal toothing disposed concentrically therewith and with ~ ., i~2~ S7 which a planet wheel engages which mates in a corresponding se~ting wi~h a toothed rack 35, through which the vehicle seat can be moved in the direction of travel or in the opposite direction~
It will be appreciated that the described arrangement i5 compact and space-saving on account of the internally ~oothed sun wheel and the mounting of the planet wheel on an eccentric. The arrangement further permits non-forcing insertion of the drive wheels or other elements such as toothed racks into engagement with the planet wheel.

Connected wi~h tne sun wheel 1 is an axle 3 which is connected with a hand wheel 4, so that the arrangement can be driven either by tne drive motor (not shown) or by hand.
There is also provided at least one planet wheel 5.
Tne external toothing ~ o~ this planet wheel engages with the internal toothing 2 of the sun wheel~ The pitch diameter d of the external toothing 6 of ~he planet wheel 5 is smaller than the pi~ch diameter ~ of the internal toothing 2 of the sun wheel 1. The planet wheel S thus engages within the sun wheel 1 t as a result of which an outstandingly compact, space-12~ ;7 saving arrangement is ensured which for the first timeopens up tne possibility of disposing this arrangement in a motor vehicle seat where space conditions are extremely limited.
Tne tooth width ~ of the external toothing 6 of the plane thwel 5 is greater than tne tooth width ~ of the internal toothing 2 of the sun wheel l.
The planet wheel 5 is movable by means of a control member in such a way that the planet wheel can be selectively engaged with any one of various driving elements allowing differen~ directions of movement of the object. In the present case tne driving elements are toothed wheels 7 to 10. The contro} member includes an eccentrie part ll and a centric part 12.
On the eccentric part ll of this eccentric arrangement 11,12 tne planet wheel 5 is rotatably mounted. It is clear ~hat the structure of the eccentric as well as the situatlon oE the individual toothed wheels 7 to 10 relative to the planet wheel 5 are so selected that in a particuldr setting position of the control member the desired engagement of thP teeth of the required toothed wheel 7 to 10 with tne teeth of tne plane~
wheel 5 or planet wheels is ef~ected. The man skilled in tlle art will appreciate how this selection may be lZ~1~457 performed for a specific case. The selection may be empirically determined.
Tne two parts 11,12 of the eccentric which forms the control member for the plane~ wheel 5 are rotatable by means of a setting lever 13 about a shaft 3. The centre line m-m of the shaft coincides with that of the driving axle 14 of the sun wheel. The setting lever 13 is guided in a setting slide 15 with several engagement positions~ Each engagement position is associated with at least one direction of movement of the objert~ The centric part 12 of the eccentric 11,12 is rota~ably mounted in tne setting slide 15 in bearings 16,17.
As ~igure 2 shows, the driving elements in ~he form of toothed wheels 7 to 10 are conne~ted with elastic shafts 18 to 21 by means of which the corresponding adjustment devices f~r tne vertical and longitudinal displacement of ~he vehicle seat can be ac~uated.
The operation of the described arrangement will now be explained in greater detail with reference to Figures 3 to 7. In this connection the position of the setting lever 13, a~ shown in ~hese Figures shoula ~e noted.
s~
I$ the motor (no~ shown) is set in motion it drives the sun wheel 1, the internal toothing 2 of which sets the plane~ wheel 5 in rotary motion by means of its external toothing 6. If the setting lever 13 assumes the engagement position represented in Figure 3 of the drawings, then tne toothed wheel 7 is in engagement with the planet wheel 5, while the toothed wheels 8 to are out of engagement. The ~oothed wheel 7 drives the elastic sha~t 18. As the toothed wheel 7 engages wi~h a toothed wheel 22 the two toothed wheels 7 and 22 ro~ate in opposite directionsL Toothed wheel 22 is connected by means of an elas~ic shaft 23 with an adjustment mechanism of the seat~ The corresponding rotary motion of elastic shafts 18 and 23 is transmitted to lif~ing devices 24,25 operating in the manner of screw drives onto tne frame 26 of the sea~ing area with the result that the latter is raised or lowered in accordance with the selected direction of rotation of the drive motor of the sun wheel 1.
The frame 26 of tne sitting area is mounted in a bearing 27~
In the representation according to Figure 4 the setting lever 13 assumes a different position represented therein. Toothed wheels 7 and 8 are in engagement wi~h planet wheel 5. The toothed wheel ~
~2~84S7 also drives toothed wheel 22. The wheel 8 drives elastic shaft 19 which is connected to a lifting device 28 on the front side of the frame 26 of the sitting area. The lifting devices 24,25 are driven by means of the elastic shafts 18,23. The frame 26 of tne sitting area is therefore raised or lowered in accordance with the direction of rotation of the drive motor of the sun wheel both at the fron~ and also at the rear.
In the representation according to Figure S only the toothed wheel 8 is in engagement with the planet wheel 5, so that on switching the driving motor of the sun wheel 1 the elastic shaf~ 19 is set in rotation and thereby the lifting device 28 is actuated. A lifting or a lowering of t~le front side of tne frame 26 of the sltting area is the result of this.
If the setting lever 13 is moved over to the position shown in Figure 6~ then only the toothed wheel 9 is in engagement with the planet wheel 5. ~oothed wheel 9 drives an elastic shaft 20 which in turn driYes a pini~n of a ra~k and pinion gear 29~3Q (~igO7). The toothed rack 30 of this rack and pinion geae 29,30 is connected with tne frame 26 of the ~itting area in such a manner tha~ in accordance with the direz~ion of i7 movement of the toothed rack 30 the vehicle seat is moved in the direction of vehicle tr2vel or in the opposite dlrection. For this purpose the frame 26 of tne sitting area is mounted in bearings 31 to 33.
The embodiment according to Figure 8 differ~ from that shown in Figures 1 to 7 essPntially in that the central axis of the arrangement and therefore of the sun wheel 1 extends approximately perpendicularly to the sltting level of the sltting area of the vehicle sea~. The setting lever 13 then assumes the position shown. In this arrangement the sun wheel 1 can be driven by mean~ of a toothed pinion 3~ which engages with a toothed crown of the sun wheel 1. In this sun wheelr for example, tnree planet wheels are disposed, the external toothed rims of which engage into ~he internal toothed rim of sun wheel 1. By means of the corresponding connection of the Pccentric connected with the setting lever 13 and bearing the planet wheels, it is possible to drive corresponding toothed wheels~ These toothed wheels also have internal ~oothed rims with which lead screws of the corresponding adjustment devices of the seat engage.
I~ is possible to provide, in addition to the internal toothing of tne toothed wheel 1, a further internal toothing disposed concentrically therewith and with ~ ., i~2~ S7 which a planet wheel engages which mates in a corresponding se~ting wi~h a toothed rack 35, through which the vehicle seat can be moved in the direction of travel or in the opposite direction~
It will be appreciated that the described arrangement i5 compact and space-saving on account of the internally ~oothed sun wheel and the mounting of the planet wheel on an eccentric. The arrangement further permits non-forcing insertion of the drive wheels or other elements such as toothed racks into engagement with the planet wheel.
