Method of heating the seat and/or backrest of a chair of a cableway system, and chair that is suitable for the purpose

Abstract

A lift chair of a cableway system is heated by heating the seat and/or the backrest upholstery of the chair while the lift chair is present in a lift station. The seat and/or backrest is heated with an electric heating device integrated into the seat and/or the backrest upholstery.

1 . A method of heating a seat and/or a backrest of a chair in a cableway system, which comprises: 
 providing at least one of a seat and/or a backrest of a chair in a cableway system with an electric heating device integrated therein; and    heating the seat and/or the backrest while the chair is in a station of the cableway system.    
   
   
       2 . The method according to  claim 1 , which comprises supplying the heating device with power for a given period of time.  
   
   
       3 . The method according to  claim 1 , which comprises controlling at least one of a duration and an intensity of a power supply in dependence on an ambient temperature.  
   
   
       4 . The method according to  claim 1 , which comprises interrupting a power supply to the heating device as soon as a temperature of the seat and/or the backrest has reached a predetermined maximum temperature value.  
   
   
       5 . The method according to  claim 1 , which comprises interrupting a power supply to the heating device when the cableway system is at a standstill.  
   
   
       6 . In a cableway system with a conveying or haulage cable, a lift chair assembly, comprising: 
 a suspension mechanism holding a chair and a clamping body for coupling said suspension mechanism to the conveying or haulage cable, and an electrically operated heating device disposed to heat said chair.    
   
   
       7 . The chair assembly according to  claim 6 , wherein said chair includes a seat rest and a backrest, and said heating device is disposed in at least one of said seat rest and said backrest of said chair.  
   
   
       8 . The chair assembly according to  claim 6 , which comprises at least one current collector disposed at said clamping body or said suspension mechanism and electrically connected to said heating device, said current collector being configured to interacts with at least one contact device disposed in a station of the cableway system.  
   
   
       9 . The chair assembly according to  claim 6 , wherein said current collector comprises roller contacts.  
   
   
       10 . The chair assembly according to  claim 6 , wherein said current collector comprises sliding contacts.  
   
   
       11 . The chair assembly according to  claim 6 , wherein the contact device has a conductor rail disposed along the conveying or haulage cable.  
   
   
       12 . The chair assembly according to  claim 6 , wherein said current collector and the contact device are part of a device for inductive power transmission.  
   
   
       13 . The chair assembly according to  claim 6 , wherein said heating device includes a heating mat and a fuse in a supply circuit of each said heating mat.  
   
   
       14 . The chair assembly according to  claim 6 , which comprises a temperature sensor disposed to sense a temperature at the chair.
