Method for Fitting a Seat Sensor Into a Seat Cushion

Abstract

A method for fitting a sensor onto a seat cushion is disclosed, which is specifically suitable for the assembly of a seat sensor onto a seat cushion, wherein the seat cushion comprises a seating surface having a central region, said central region of said seating surface being at least partially delimited by a groove extending from said seating surface into said seat cushion, and wherein said sensor comprises a first sensor portion to be arranged at least partially at a periphery of said central region. The method comprises the steps of providing a mould ( 10 ) for foaming said seat cushion, said mould comprising at least one ridge ( 14 ) designed for forming said groove into said seating surface of said seat cushion; arranging said first sensor portion ( 18 ) in said mould on said at least one ridge ( 14 ), and foaming said seat cushion, thereby integrating at least part of said first sensor ( 18 ) portion into said seat cushion.

1 . A method for fitting a sensor onto a seat cushion, wherein said seat cushion comprises a seating surface having a central region, said central region of said seating surface being at least partially delimited by a groove extending from said seating surface into said seat cushion, and wherein said sensor comprises a first sensor portion to be arranged at least partially at a periphery of said central region, the method comprising
 providing a mould for foaming said seat cushion, said mould comprising at least one ridge designed for forming said groove into said seating surface of said seat cushion;   arranging said first sensor portion in said mould on said at least one ridge, and foaming said seat cushion, thereby integrating at least part of said first sensor portion into said seat cushion.   
   
   
       2 . A method according to  claim 1 , wherein said arranging said first sensor portion in said mould comprises attaching auxiliary inserts onto said ridge and fastening said first sensor portion onto said auxiliary inserts. 
   
   
       3 . A method according to  claim 2 , wherein said auxiliary inserts comprise a base portion and a clip portion extending from said base portion, said clip portion for clipping said auxiliary insert onto an upper edge of said ridge. 
   
   
       4 . A method according to  claim 3 , wherein said clip portion of said auxiliary insert is adapted for attaching a seat trim. 
   
   
       5 . A method according to  claim 2 , wherein said auxiliary inserts are adapted to position a metal wire into said mould, said metal wire extending along said ridge for being at least partially foamed into said cushion. 
   
   
       6 . A method according to  claim 1 , wherein said sensor further comprises a second sensor portion to be arranged on top of said seating surface of said seat cushion, said method further comprising inserting said second sensor portion into a cavity within said mould. 
   
   
       7 . A method according to  claim 6 , wherein said first sensor portion and said second sensor portion are connected to a common connection terminal by means of flexible connection strips.
