Abstract

The invention relates to a terminal end piece ( 8 ) for a wiper blade. The terminal end piece ( 8 ) comprises a peripheral wall ( 20 ) which separates an external environment of the terminal end piece ( 8 ) from an internal space ( 11 ) of the terminal end piece ( 8 ). The terminal end piece ( 8 ) delimits a first housing ( 21 ) which is arranged in the internal space ( 11 ) and which extends primarily in a first plane (P 1 ). A second housing ( 22 ) is interposed between the peripheral wall ( 20 ) and the first housing ( 21 ). The terminal end piece ( 8 ) comprises at least one locking member ( 37 ) which is configured to connect the terminal end piece ( 8 ) to a flexible support ( 6 ) of the wiper blade ( 1 ). The locking member ( 37 ) extends at least from the peripheral wall ( 20 ) and comprises a stop ( 46 ) which is at least partially arranged in the first housing ( 21 ), the locking member ( 37 ) being configured so that the stop ( 46 ) can be displaced in a second plane (P 2 ) transverse to the first plane (P 1 ) when the first end ( 31 ) is introduced into the first housing ( 21 ).

First claim

The invention claimed is:

1. A terminal end piece for a wiper blade, the terminal end piece comprising:
a peripheral wall which separates an external environment of the terminal end piece from an internal space of the terminal end piece,
the terminal end piece delimiting a first housing which is arranged in the internal space and which extends primarily in a first plane, a second housing being interposed between the peripheral wall and the first housing; and
at least one locking member which is configured to connect the terminal end piece to a flexible support of the wiper blade,
wherein the locking member extends from the peripheral wall and comprises a stop which is at least partially arranged in the first housing, the locking member being configured so that the stop can be moved in a second plane transverse to the first plane,
wherein the first housing and the second housing are delimited by at least one internal wall, and
wherein the locking member comprises a base which extends from the peripheral wall to the internal wall.

2. The terminal end piece according to claim 1 , wherein the first housing is configured to receive a first end of the flexible support of the wiper blade.

3. The terminal end piece according to claim 1 , wherein the second housing is configured to receive a heel of a scraper blade of the wiper blade.

4. The terminal end piece according to claim 1 , wherein the locking member comprises a central body which is fixedly joined to the base which extends along an extension axis which forms with the first plane a first angle which is between 30° and 60°.

5. The terminal end piece according to claim 4 , wherein the first angle is 45° plus or minus 10%.

6. The terminal end piece according to claim 4 , wherein the locking member comprises a head which is fixedly joined to the central body and which is received inside the first housing.

7. The terminal end piece according to claim 6 , wherein the head comprises the stop, the stop being intended to come into contact with a first edge which comprises a notch which is provided through the flexible support.

8. The terminal end piece according to claim 6 , wherein the head is mounted so as to be movable in rotation about a rotation axis which extends in the central body.

9. The terminal end piece according to claim 1 , wherein the locking member is in the form of a flattened “S” when viewed in the second plane.

10. A wiper blade comprising:
a terminal end piece comprising:
a peripheral wall which separates an external environment of the terminal end piece from an internal space of the terminal end piece;
the terminal end piece delimiting a first housing which is arranged in the internal space and which extends primarily in a first plane, a second housing being interposed between the peripheral wall and the first housing;
at least one locking member which is configured to connect the terminal end piece to a flexible support of the wiper blade;
wherein the locking member extends at least from the peripheral wall and comprises a stop which is at least partially arranged in the first housing, the locking member being configured so that the stop can be moved in a second plane transverse to the first plane;
wherein the first housing and the second housing are delimited by at least one internal wall; and
wherein the locking member comprises a base which extends from the peripheral wall to the internal wall;

a scraper blade; and
wherein the flexible support comprises a first end accommodated inside the first housing.
