Abstract:
1. A seat intended to be mounted on a toilet bowl ( 1 ) having a top and an opening into the top, characterised in that the seat comprises a toilet seat ( 4 ) adapted to be applied on the top of the bowl ( 1 ) by two laterally spaced threaded rods ( 16 ) for fixing the toilet seat ( 4 ) on the toilet bowl ( 1 ), the toilet seat ( 4 ) having a shape adapted to a shape of the bowl ( 1 ) while providing a front air inlet ( 6 ), a rear air outlet ( 7 ) aligned between the two laterally spaced threaded rods ( 16 ) and two lateral parts ( 5 ) on a lower face of the toilet seat ( 4 ) and extending between the front air inlet ( 6 ) and the rear air outlet ( 7 ), the lateral parts ( 5 ) being configured to rest in a sealed manner on the top of the toilet bowl ( 1 ) at all lateral positions between the front air inlet ( 6 ) and the rear air outlet ( 7 ), an air box ( 8 ) between the threaded rods ( 16 ) and communicating with said rear air outlet ( 7 ), a duct ( 9 , 10 ) extending from the rear air outlet ( 7 ) and being adapted to be connected to an air extraction system ( 14 , 15 ), and a cover ( 11 ) connected to the seat ( 4 ) at a location in proximity to the rear air outlet ( 7 ) and the air box ( 8 ), the cover ( 11 ) having a lower shoulder disposed and dimensioned to project to a position below the top of the toilet bowl ( 1 ) and to seal the front air inlet ( 6 ) between the toilet seat ( 4 ) and the toilet bowl ( 1 ) when the cover ( 11 ) is in a closed position so that the toilet bowl ( 1 ) is sealed sufficiently to avoid release of malodorous gases from the toilet bowl ( 1 ) when the cover ( 11 ) is in the closed position, the cover ( 11 ) further having a handle ( 13 ) disposed to prevent access to a flush activator ( 3 ) of the toilet bowl when said cover ( 11 ) is in an open position and when the lateral parts of the toilet seat rest in a sealed manner on the toilet bowl.
