CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation of application no. PCT/EP2005/012946, filed Dec. 2, 2005, which claims the priority of German application no. 10 2005 001 875.0, filed Jan. 14, 2005, and each of which is incorporated herein by reference. FIELD OF THE INVENTION [0002] The invention relates to a chair with a base body, and with at least two upholstered support parts provided on the base body for supporting a person resting on the chair, in use, and the support parts including a seat part. BACKGROUND OF THE INVENTION [0003] Chairs of this type are known, for example, in the form of motor-driven adjustable chairs having parts that can be adjusted in relation to one another electromechanically, for example a calf part, designed to support the leg or calf region of a person resting in the chair, which can be adjusted relative to a seat part. For adjusting the parts of the piece of furniture relative to one another, an electromechanical adjustment device is provided, which has a drive unit with an electric motor. [0004] From DE 101 23 380 C2, a chair of the relevant type is known, which has a base body and upholstered seat parts provided on the base body to support a person resting on the chair. With the known chair, the support parts are formed by a seat part, a foot support that can be pivoted outward, and a backrest that is capable of pivoting, wherein an electromechanical adjustment device, provided beneath the seat part, is provided for implementing the adjustment. [0005] Motorized adjustable chairs are also known from DE 196 45 456 A1, DE 199 45 118 A1, DE 199 02 467, DE 102 07 360 B4, DE 20 2005 003 961 U1, DE 203 19 483 U1 and DE 198 44 240 C2. [0006] To conceal the electromechanical adjustment device provided underneath the seat part, casing or some similar covering is provided in the known chairs. [0007] One disadvantage of the known chairs is that they are relatively bulky and therefore unattractive. OBJECTS AND SUMMARY OF THE INVENTION [0008] An object of the invention is to provide a chair of the type a chair with a base body, and with at least two upholstered support parts provided on the base body for supporting a person resting on the chair, in use, and the support parts including a seat part, and which chair does not have the disadvantages of known chairs and is therefore configured in a more visually advantageous manner. [0009] This and other objects are achieved by the inventive chair which includes a base body, at least two upholstered support parts provided on the base body, and the at least two upholstered support parts being configured to support a person resting on the chair, in use. The support parts include a seat part. An electromechanical adjustment device is provided which includes at least one electric motor for adjusting at least one of the at least two upholstered support parts relative to one of the base body and to one of the at least two upholstered support parts, and being integrated into the seat part without projecting out, and in such a way that the electric motor does not project beyond an outer boundary surface of the seat part. In this manner, at least the electric motor is concealed and is no longer visible, so that the chair has a pleasing visual appearance. [0010] The basic idea of the teaching of the invention includes integrating at least one electric motor of an electromechanical adjustment device for adjusting at least one of the seat parts relative to the base body and/or relative to another seat part, into the seat part without projecting out. In this manner, at least the electric motor is concealed and is no longer visible, so that the chair of the invention is configured to have an advantageous and pleasing visual appearance. Because the electromechanical adjustment device is not visible or is barely visible, the chair of the invention conveys the overall visual impression of a non-motorized adjustable chair. The invention represents a departure, for the first time, from the idea of adjusting the seat part of a chair by use of an adjustment device, such as a scissor mechanism, provided underneath the seat part. Thus for the first time, the invention provides a chair, in which at least one electric motor, but especially also the essential components of a complete electromechanical adjustment device, are integrated into the seat part. [0011] A particular advantage of the chair of the invention is that, due to the integration of the electric motor into the seat part, costly casing on the seat part designed to cover the electric motor or the electromechanical adjustment device is not necessary. Because of this, the chair of the invention is substantially sleeker looking than known chairs. A further advantage of integrating the electric motor into the seat part is the substantial increase in design freedom this allows with the chair of the invention. [0012] If the electromechanical adjustment device has only one electric motor, the motor is integrated into the seat part according to the invention without projecting out. However, it is also possible according to the invention for the electromechanical adjustment device to have at least two electric motors, which are integrated into the seat part according to the invention without projecting out. For example, and especially, it is possible according to the invention to integrate multiple electric motors into the seat part, one of which is allocated to the seat part for adjustment of the same, with at least one other being allocated to another seat part for adjustment of the same. [0013] In principle, the electric motor can be integrated into a seat part that remains stationary during adjustment of the seat parts relative to one another or relative to a base body. However, one particularly advantageous further improvement on the teaching of the invention provides that the seat part in which the electric motor is integrated can be moved during adjustment. In this embodiment, the adjustment device, together with the electric motor, can be integrated essentially completely into the respective seat part that can be moved during adjustment. In this manner, mechanical parts of the adjustment device can be particularly simple in configuration. In particular, short levers can be used. [0014] Another exceptionally advantageous further improvement of the teaching of the invention provides that the adjustment device has at least one linear drive, an output member of which is drivingly connected to the electric motor, and that the linear drive is integrated into the seat part without projecting out. In this embodiment, the integration of components of the adjustment device into the seat part is further increased. [0015] One advantageous further improvement on the aforementioned embodiment provides that the linear drive has a spindle drive. Spindle drives of this type are available as simple and cost-effective standard components. They are robust and suited to applying large amounts of force. [0016] One advantageous further improvement on the aforementioned embodiment provides that the output member of the spindle drive is a spindle nut, which is provided, fixed against rotation, and movable in an axial direction, on a rotary actuatable threaded spindle, which is in drive connection with the electric motor. In a kinematic inversion of the aforementioned embodiment, however, the output member of the spindle drive can also be a threaded spindle, which is mounted, fixed against rotation, and movable in its axial direction, and on which a stationary, rotary actuatable spindle nut is provided, which is in drive connection with the electric motor. [0017] Another further improvement on the teaching of the invention provides that the seat part is connected to the base body or to an adjacent seat part, preferably exclusively, via at least one lever-type brace. In this embodiment, with the exception of the brace, which can especially form a part of the adjustment device, all the components of the adjustment device can be integrated into the seat part, so that a particularly pleasing overall visual impression is produced. [0018] An advantageous further improvement on the aforementioned embodiment provides that the lever-type brace is configured to be flat, perpendicular to its longitudinal extension. This causes the brace to visually recede into the background. [0019] Another advantageous further improvement on the teaching of the invention provides that at least two electric motors are integrated into the seat part, one of which is assigned to the seat part for adjustment of the same, while at least one other is assigned to a different seat part for adjustment of the same. [0020] Another advantageous further improvement on the teaching of the invention provides that the electromechanical adjustment device, including at least one electric motor, is positioned beneath an upholstered cushion of the seat part, and that device for relieving the pressure on the electromechanical adjustment device are provided between the cushion and the electromechanical adjustment device. In this manner, it is reliably prevented that when a load is applied to the seat surface of the seat part, for example under the weight of a person seated on the chair, pressure is exerted on the components of the electromechanical adjustment device.
