The windscreen wiper device includes a wiper strip extending in a longitudinal direction between opposite wiper strip ends, and the wiper strip is of a flexible material such as rubber for sealing against the windshield. At least one carrier element is disposed in the grooves and extends in a longitudinal direction between opposite carrier element ends. The windscreen wiper device further includes a frame structure including a plurality of claws in sliding engagement with the carrier element or elements and wherein the frame structure extends longitudinally past the ends of the wiper strip and the carrier element or elements. The frame structure includes a pair of flange portions that restrict the movement of the carrier element and the wiper strip relative to the frame structure. ## Claims ### Claim 1 A windscreen wiper device for cleaning a windshield of a vehicle, comprising: an elongated wiper strip extending in a longitudinal direction between opposite wiper strip ends and being of a flexible material for sealing against the windshield; said wiper strip presenting a pair of grooves extending in said longitudinal direction; at least one carrier element disposed in said grooves and extending in said longitudinal direction between opposite carrier element ends; a frame structure including a plurality of claws in sliding engagement with said at least one carrier element and wherein said frame structure extends longitudinally past both of said wiper strip ends and both said carrier element ends; and wherein said frame structure includes a pair of flange portions that restrict the movement of said carrier element and wiper strip relative to said frame structure. ### Claim 2 (depends on 1) The windscreen wiper device as set forth in claim 1 wherein said at least one carrier element has a generally constant cross-section along its entire length. ### Claim 3 (depends on 1) The windscreen wiper device as set forth in claim 1 wherein said frame structure includes a main bridge and a pair of end piece sub-assemblies coupled to opposite ends of said main bridge. ### Claim 4 (depends on 3) The windscreen wiper device as set forth in claim 3 wherein each of said end piece sub-assemblies includes an end cap having one of said flange portions. ### Claim 5 (depends on 4) The windscreen wiper device as set forth in claim 4 wherein said flange portions extend in a downward direction. ### Claim 6 (depends on 4) The windscreen wiper device as set forth in claim 4 wherein each of said end caps includes at least two holding elements wrapping partially around said at least one carrier element and spaced longitudinally from said flange portion. ### Claim 7 (depends on 6) The windscreen wiper device as set forth in claim 6 wherein said holding elements are generally L-shaped. ### Claim 8 (depends on 3) The windscreen wiper device as set forth in claim 3 wherein each of said end piece sub-assemblies also includes at least one linkage having at least one set of said claws in sliding engagement with said at least one carrier element. ### Claim 9 (depends on 8) The windscreen wiper device as set forth in claim 8 wherein each of said end piece sub-assemblies includes a connecting piece interconnecting said linkage and said end cap with said main bridge. ### Claim 10 (depends on 9) The windscreen wiper device as set forth in claim 9 wherein said connecting piece of each end piece sub-assembly includes sets of apertures for receiving posts on said end cap and said linkage to establish pivoting relationships between said end cap and said connecting piece and between said linkage and said connecting piece. ### Claim 11 (depends on 9) The windscreen wiper device as set forth in claim 9 wherein each of said connecting pieces is generally U-shaped as viewed in cross-section with a pair of side walls and an upper wall. ### Claim 12 (depends on 11) The windscreen wiper device as set forth in claim 11 wherein said apertures on said connecting pieces are on said side walls. ### Claim 13 (depends on 11) The windscreen wiper device as set forth in claim 11 wherein each of said connecting pieces includes a spring loaded tab on its upper wall for snapping into engagement with said main bridge. ### Claim 14 (depends on 1) The windscreen wiper device as set forth in claim 1 wherein said at least one carrier element is further defined as a pair of carrier elements. ### Claim 15 (depends on 1) The windscreen wiper device as set forth in claim 1 wherein said frame structure is generally spoiler shaped.
