Seat, in Particular Aircraft Passenger Seat

Abstract

The invention relates to a seat, in particular an aircraft passenger seat ( 1 ), comprising seat components such as a backrest ( 9 ), seat section ( 5 ), seat frame, seat cushion and cover material and seat attachment parts such as a headrest ( 15 ), armrest and footrest. At least one of the seat components is equipped with at least one guide web ( 17 ), along which a seat attachment part ( 15 ) can be displaced and fixed in a friction fit in a predetermined position.

1 . A seat ( 1 ), in particular an aircraft passenger seat, having seat components such as the backrest ( 9 ), seat part ( 5 ), seat frame, seat cushion ( 11 ) and upholstery material ( 13 ) and with accessory seat parts such as a headrest ( 15 ), armrest and leg rest, characterized in that in at least one of the seat components there is at least one guide web ( 17 ) along which one accessory seat part can be moved and fixed in predetermined positions in a friction fit. 
   
   
       2 . The seat as claimed in  claim 1 , wherein the guide web ( 17 ) is formed by the edge ( 21 ) of the upholstery material ( 13 ) which runs in the guide direction. 
   
   
       3 . The seat as claimed in  claim 2 , wherein in the upholstery material ( 13 ) at least one slot which runs in the guide direction is formed, with one edge ( 21 ) forming the guide web ( 17 ). 
   
   
       4 . The seat as claimed in  claim 3 , wherein the edges ( 19 ,  21 ) of the upholstery material ( 13 ) which border the slot overlap slightly and wherein the edge ( 21 ) of the upholstery material ( 13 ) lying at the top on the overlap which has been formed in this way forms the guide web ( 17 ). 
   
   
       5 . The seat as claimed in  claim 1 , wherein there is a clamping means ( 23 ) which produces a clamping force between the guide web ( 17 ) and the movable accessory seat part ( 15 ) for forming the friction fit. 
   
   
       6 . The seat as claimed in  claim 5 , wherein there is a clamping spring ( 23 ) which produces the clamping force with spring legs ( 25 ,  27 ) which clamp the edge ( 21 ) of the upholstery ( 13 ) which forms the guide web ( 17 ) between themselves. 
   
   
       7 . The seat as claimed in  claim 6 , wherein a clamping spring ( 23 ) with a flat spring leg ( 25 ) which is connected to the accessory seat part ( 15 ) and which transmits the clamping force to the top of the edge ( 21 ) of the upholstery material ( 13 ) overlapped by the clamping spring ( 23 ), with a turning part ( 29 ) which encompasses the edge ( 21 ) of the upholstery material ( 13 ) and an arched second spring leg ( 27 ), with its convexity transmitting the clamping force to the back of the edge ( 21 ) of the overlapped upholstery material ( 13 ). 
   
   
       8 . The seat as claimed in  claim 7 , wherein the arched second spring leg ( 27 ) on the overlap formed on the slot can be displaced along the top of the overlapped upholstery material ( 13 ). 
   
   
       9 . The seat as claimed in  claim 7 , wherein along the edge ( 21 ) of the upholstery material ( 13 ) overlapped by the clamping spring ( 23 ), there is piping on it which is surrounded at least partially by the turning part ( 29 ) of the clamping spring ( 23 ), which part is located between the spring legs ( 25 ,  27 ). 
   
   
       10 . The seat as claimed in  claim 4 , wherein there are two slots, which are adjacent to the side edges of the backrest ( 9 ) and which run parallel to one another in the longitudinal direction of the backrest ( 9 ) and wherein the upholstery material ( 13 ) which runs between the slots on the overlap of the slots forms the upholstery material ( 13 ) which lies at the top, with the respective edge ( 21 ) forming the guide web ( 17 ) for an accessory seat part ( 15 ) which is guided to be movable in the longitudinal direction on the two slots. 
   
   
       11 . The seat as claimed in  claim 10 , wherein the accessory seat part is a movable headrest ( 15 ).
