Title: Body-Adaptable Arm Rest Arrangement

Description:
BACKGROUND AND SUMMARY OF THE INVENTION 
     The invention relates to a body-adaptable armrest arrangement. 
     Such an arrangement is known from DE 10 2007 009 283 A1, although this involves merely a height-adjustable armrest in which an armrest arrangement is arranged, via a wedge, on a base surface and is designed to be height-adjustable. 
     The disadvantage of such an adjustable armrest can be considered, in particular, the fact that it allows only limited adaptation to a user&#39;s requirements, wherein in particular people of small stature can use such an armrest only to a very limited extent, if at all. 
     It is therefore the object of the present invention to provide an armrest arrangement having an armrest and an actuating device for setting different armrest positions. The armrest arrangement should make it possible to realize an entire range of adjustments with adjustment options in the upward and downward, forward and rearward directions and about a Y axis. 
     This object is achieved according to the invention by providing a body-adaptable armrest arrangement which comprises an armrest and an actuating device for setting different rest positions. The armrest here is connected to a base, for example in the form of a motor-vehicle bodyshell or of a seat frame, via the actuating device. 
     Height adjustment, inclination adjustment and length adjustment can be achieved as a result. 
     Accordingly, the body-adaptable armrest arrangement according to the invention is capable of meeting stringent requirements relating to use and comfort and also of adapting to a user&#39;s stature, irrespective of the position the user wants to assume or the position which he has already assumed in the seat. 
     The actuating device preferably has at least three actuators, wherein, in a further, particularly preferred embodiment, first and second actuators of the three actuators are connected in each case to first and second end points of the base and first and second end points of the armrest. The third actuator here is preferably connected to the second end of the base and the first end of the armrest, or, in an alternative embodiment, it is possible for the third actuator to be connected to the first end point of the base and, accordingly, to the second end point of the armrest. 
     In a particularly preferred embodiment, the armrest can be designed in the form of a central armrest or, as an alternative, in the form of a console. 
     The actuators can be designed, for example, in the form of spindle drives or cylinders, in particular hydraulic cylinders. In both cases, of course, necessary drives, for example electromotive drives, transmission elements and control units, are likewise provided as an option. 
     Further details, features and advantages of the invention can be gathered from the following description of exemplary embodiments with reference to the drawings.

     DETAILED DESCRIPTION OF THE DRAWINGS 
     The construction of a body-adaptable armrest arrangement  4  can be gathered, in particular, from the illustration of  FIG. 1 . The latter shows that the armrest arrangement  4  has an armrest  1 , which can be, for example, a central armrest. The armrest arrangement  4  also has an actuating device  2 , which is provided for setting different positions of the rest, wherein  FIG. 1  illustrates the position defined by the letter A, wherein  FIGS. 2 to 4  identify alternative positions using the letters B, C and D. 
     In the case of the inventive armrest arrangement  4 , the actuating device  2  connects the armrest  1  to a base  3 , which can be, for example, a bodyshell of a motor vehicle or a seat frame or the like. 
     In the case of the particularly preferred embodiment which is illustrated in  FIG. 1 , the actuating device has three actuators  2 A,  2 B and  2 C. 
     The actuators  2 A and  2 B here are first and second actuators, respectively, which are fastened at first and second end points  3 A,  3 B of the base  3  and, at their other end, to first end points  1 A and  1 B of the armrest  1 . Also provided is a third, central actuator  2 C, which is arranged between the first actuator  2 A and the second actuator  2 B. As  FIG. 1  depicts, this third actuator  2 C runs along a diagonal and, accordingly, is connected to the first end  1 A of the armrest  1  and the second end or end point  3 B of the base  3 . 
     It would also be possible, in principle, for the third actuator  2 C to be connected to the first end point  3 A of the base  3  and, accordingly, in this case to the second end point  1 B of the armrest  1 . 
     If the actuators  2 A to  2 C are designed in the form of cylinders, the piston rods thereof, depending on the position which the armrest  1  is to assume or has assumed, are retracted and/or extended in order to actuate the armrest  1  for height adjustment, inclination adjustment or length adjustment. 
     Thus,  FIG. 2  shows the armrest  1  lowered in the direction of a bench seat (not illustrated specifically in  FIG. 2 ). The lowering of the armrest makes it possible for items to be pushed through on the bench seat. 
       FIG. 3  shows the position C, in which the armrest  1  has been displaced rearward, as seen in the direction of travel of the vehicle (not illustrated in  FIG. 3 ), that is to say to a rear region of the passenger compartment. This means that the armrest  1  becomes an element of interaction between the front and rear rows of seats. For example, items positioned on the armrest can thus be passed from front to rear. 
       FIG. 4  depicts the position D, in which the armrest  1  has been raised and inclined by the appropriate setting of the actuators  2 A to  2 C, in order to render accessible for example a glove compartment which is arranged beneath the base  3 . The armrest  1  can thus perform a cover function, e.g. for the aforementioned glove compartment.
