Windscreen wiper device

1. A windscreen wiper device of the flat blade type comprising an elastic, elongated carrier element, as well as an elongated wiper blade of a flexible material, which can be placed in abutment with a windscreen to be wiped, which wiper blade includes at least one groove, in which groove a longitudinal strip of the carrier element is disposed, wherein free ends of said wiper blade are connected to a respective connecting piece, which windscreen wiper device comprises a connecting device for an oscillating wiper arm, and wherein said wiper blade is provided with a spoiler at a side thereof facing away from said windscreen to be wiped, wherein at least one of said connecting pieces comprises an internal reinforcement rib connecting lateral sides of said connecting piece, wherein said spoiler is removed along a portion of the length of said wiper blade at a free end of said wiper blade facing said connecting piece, and wherein in mounted position said internal reinforcement rib abuts said spoiler and wherein said connection of each of said connecting pieces to said free ends of said wiper blade is independent of any connection between said connecting pieces and said carrier element, such that there is no direct connection between said connecting pieces and said carrier element that would serve to secure the connecting pieces against removal from said wiper element, but rather a direction connection between said connecting pieces and said wiper blade.

2. A windscreen wiper device according to claim 1 , wherein said spoiler is cut away, wherein in mounted position said internal reinforcement rib abuts a straight free end of said spoiler.

3. A windscreen wiper device according to claim 1 , wherein said connecting piece comprises engaging members sidewardly engaging said wiper blade from the outside, wherein said engaging members comprise retaining structure for retaining said wiper blade onto said connecting piece.

4. A windscreen wiper device according to claim 3 , wherein said engaging members and said retaining structure are in one piece.

5. A windscreen wiper device according to claim 4 , wherein said engaging members and said retaining structure are formed by inwardly bent parts of edges of said lateral sides of said connecting piece.

6. A windscreen wiper device according to claim 3 , wherein a cross plane through a free end of said internal reinforcement rib extends through said retaining structure.

7. A windscreen wiper device according to claim 3 , wherein said retaining structure comprises at least one sidewardly extending gripping tooth for gripping an intermediate web of said wiper blade.

8. A windscreen wiper device according to claim 7 , wherein said retaining structure comprises at least two sidewardly extending gripping teeth in the form of books, and wherein said hooks are bent in a direction away from the connecting device in order to block any movement of said wiper blade in a direction away from said connecting piece.

9. A windscreen wiper device according to claim 1 , wherein said lateral sides of said connecting piece are movable between a first position facing away from the wiper blade, wherein said connecting piece is disconnected from said wiper blade, and a second position facing towards the wiper blade, wherein said connecting piece is connected to said wiper blade.

10. A windscreen wiper device according to claim 1 , wherein said at least one of said connecting pieces and said reinforcement rib are made of plastic, but overmoulded on a metallic part in order to increase the stiffness thereof.
