Abstract

The invention relates to an end piece ( 11 ) of a windshield wiper comprising at least one spring strip ( 5 ) and a wiper blade ( 1 ). The end piece ( 11 ) has a first part ( 12 ) and a second part ( 13 ). The first part ( 12 ) includes a recess for accommodating the spring strip ( 5 ), a cavity for accommodating the wiper blade ( 1 ), and a hole ( 28 ) that is in communication with the recess and the cavity. The second part ( 13 ) includes a locking means for blocking the end piece ( 11 ) relative to the wiper, said locking means extending inside the hole ( 28 ). The first pan ( 12 ) and the second part ( 13 ) are connected to each other by a removable attachment means ( 14 ). The end piece is for use in motor vehicles.

First claim

The invention claimed is:

1. An end fitting of a wiper, said wiper having at least one vertebra and a wiper blade, the end fitting comprising:
a primary part and a secondary part, the primary part comprising:
a housing that is able to receive the vertebra,
a recess that is able to receive the wiper blade, and
a hole which opens into the housing and into the recess,

said secondary part comprising a locking means that is able to immobilize the end fitting with respect to the wiper,
the primary part and the secondary part being connected by a removable fastening means,
wherein the vertebra comprises an orifice that passes through the vertebra from one side to another side,
wherein the vertebra is a separate and independent constructional element from the wiper blade,
wherein the wiper blade is elongated in a longitudinal direction and the end fitting covers a terminal longitudinal end of the wiper blade,
wherein the wiper blade includes a cutout,
wherein the locking means extend into the hole, the orifice, and the cutout, and
wherein the housing and the recess are separate.

2. The end fitting as claimed in claim 1 , wherein the primary part is formed by a body through which the hole passes and at a periphery of which the removable fastening means is formed.

3. The end fitting as claimed in claim 2 , wherein the body has an upper face delimiting the housing, an intermediate wall which delimits both the housing and the recess, wherein the hole is made in the upper face and in the intermediate wall.

4. The end fitting as claimed in claim 1 , wherein the secondary part covers the primary part when the wiper is placed in a horizontal plane.

5. The end fitting as claimed in claim 1 , wherein the removable fastening means is produced by cooperating shapes between the primary part and the secondary part.

6. The end fitting as claimed in claim 1 , wherein the removable fastening means comprises at least one constituent male cylindrical portion of the primary part and a female cylindrical portion formed on the secondary part.

7. The end fitting as claimed in claim 6 , wherein the at least one constituent male cylindrical portion is formed by a tube having a peripheral wall which extends peripherally through 360°, while the female cylindrical portion is formed by a circular arc which extends peripherally between 181° and 270°.

8. The end fitting as claimed in claim 1 , wherein the locking means is arranged with respect to the primary part so as to prevent a movement in translation between the primary part and the vertebra.

9. The end fitting as claimed in claim 1 , wherein the locking means is arranged with respect to the primary part so as to prevent a movement in translation between the primary part and the wiper blade.

10. The end fitting as claimed in claim 1 , wherein the locking means is produced in one piece with the secondary part and forms a protuberance which extends into an internal volume of the secondary part, said internal volume being delimited by a constituent peripheral wall of the secondary part.

11. The end fitting as claimed in claim 10 , wherein a free end of the protuberance comprises at least one tooth that is able to deform the wiper blade.

12. The end fitting as claimed in claim 1 , further comprising a blocking means that is able to plug a constituent liquid channeling device of the wiper.

13. A wiper comprising:
at least one vertebra,
a wiper blade; and
an end fitting comprising:
a primary part and a secondary part, the primary part comprising:
a housing that is able to receive the vertebra,
a recess, separate from the housing, that is able to receive the wiper blade, and
a hole which opens into the housing and into the recess,

said secondary part comprising a locking means that is able to immobilize the end fitting with respect to the wiper,
the primary part and the secondary part being connected by a removable fastening means,
wherein the vertebra is a separate and independent constructional element from the wiper blade that comprises an orifice that passes through the vertebra from one side to another side,
wherein the wiper blade comprises a cutout and is elongated in a longitudinal direction, wherein the end fitting covers a terminal longitudinal end of the wiper blade, and
wherein the locking means extend into the hole, the orifice, and the cutout.

14. The wiper as claimed in claim 13 , further comprising at least one liquid channeling device for feeding a windshield washer liquid.

15. The wiper as claimed in claim 14 , the primary part comprising blocking means for closing the at least one liquid channeling device.

16. The end fitting as claimed in claim 1 , the primary part comprising blocking means for closing at least one liquid channeling device of the wiper.

17. The end fitting as claimed in claim 1 , wherein the orifice of the vertebra is produced at a center of the vertebra along a transverse axis perpendicular to a longitudinal axis.

18. The end fitting as claimed in claim 1 , wherein the orifice of the vertebra is open on a longitudinal side of the vertebra.
