Chair

Abstract

Chair 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.

1 . Chair, comprising: 
 a) a base body;    b) at least two upholstered support parts provided on the base body, the at least two upholstered support parts being configured to support a person resting on the chair, in use;    c) the support parts including a seat part; and    d) an electromechanical adjustment device including 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.    
   
   
       2 . Chair according to  claim 1 , wherein: 
 a) the seat part in which the electric motor is integrated is capable of moving in an adjustment motion.    
   
   
       3 . Chair according to  claim 1 , wherein: 
 a) the adjustment device has at least one linear drive including an output member; and    b) the output member is in drive connection with the electric motor, and the at least one linear drive is integrated into the seat part without projecting out.    
   
   
       4 . Chair according to  claim 3 , wherein: 
 a) the linear drive includes a spindle drive.    
   
   
       5 . Chair according to  claim 4 , wherein: 
 a) an output member of the spindle drive includes a spindle nut, which is provided, fixed against rotation, and movable in an axial direction, on a threaded spindle which can be rotary actuated and is in drive connection with the electric motor.    
   
   
       6 . Chair according to  claim 1 , wherein: 
 a) the seat part is connected to one of the base body and to the seat part via at least one lever-type brace.    
   
   
       7 . Chair according to  claim 6 , wherein: 
 a) at least one lever-type brace is configured as flat perpendicular to its longitudinal extension.    
   
   
       8 . Chair according to  claim 1 , wherein: 
 a) the at least one electric motor includes at least two electric motors which are integrated into the seat part and without projecting out; and    b) at least one of the at least two electric motors is allocated to the seat part for adjustment of the same, and at least one of the at least two electric motors is allocated to one of the at least two upholstered support parts for adjustment of the same.    
   
   
       9 . Chair according to  claim 1 , wherein: 
 a) the electromechanical adjustment device including the at least one electric motor is provided underneath an upholstered cushion of the seat part; and    b) between the cushion and the electromechanical adjustment device, a device configured for relieving the pressure of the electromechanical adjustment device is provided.    
   
   
       10 . Chair according to  claim 9 , wherein: 
 a) the device for relieving the pressure of the electromechanical adjustment device includes a frame which encompasses the electromechanical adjustment device, which extends in the direction of the seat part up to at least an upper boundary plane of the electromechanical adjustment device, and upon which the cushion rests.
