Abstract

The present disclosure relates to a connection base for carrying a wiping blade and to be attached to an adapter that can be connected to an actuation arm for forming with said adapter a mechanical connector for a wiper blade for an automobile, the adapter having an elongated shape with first and second ends, characterised in that it includes a retaining linear guide for the first end of the adapter and removable attachment means of the second end supported on the one hand by the adapter and on the other hand by the base. The present disclosure also relates to a conform adapter, to a mechanical connector formed by the adapter and the connection base, to a planar wiper blade and to a wiping device.

First claim

The invention claimed is:

1. A connection base configured to support a wiping blade and to be attached to an adapter, the connection base comprising:
a first and a second longitudinal end, wherein the connection base has an elongated longitudinal shape in the same direction as the wiper blade,
wherein the first longitudinal end comprises a retaining linear guide for a first end of the adapter, the retaining linear guide dimensioned for sliding engagement with the adapter and disposed inside the connection base,
wherein the retaining linear guide is provided by base walls arranged to form two insertion channels being spaced apart and each insertion channel having a laterally inward-facing side and walls extending laterally inward past the base wall, configured to receive associated side parts of the first end of the adapter,
wherein the second longitudinal end comprises removable attachment complementary means for a second end of the adapter, distinct from the retaining linear guide, said removable attachment complementary means formed by snapping means, wherein the connection base houses the removable attachment complementary means, and
wherein the snapping means include two resilient arms comprising a shape of a fork and configured to receive an associated pin of the second end of the adapter.

2. A connection base according to claim 1 , wherein each channel is formed by a portion of a side skirt of the base providing a side guiding of said first longitudinal end, and by a portion of a wall perpendicular to the side skirt, wherein the portion of the wall prevents movement of said first longitudinal end according to a direction perpendicular to a general plane defined by said connection base.

3. A connection base according to claim 1 , wherein the snapping means include two arm-pin pairs.

4. A connection base according to claim 1 , further comprising a centering form configured to cooperate with a matching form of the adapter.

5. The connection base according to claim 4 , wherein the centering form is a square opening in a planar surface of the connection base, facing the adapter.

6. A connection base according to claim 1 , further comprising a wiping blade retaining channel.

7. A connection base according to claim 1 , wherein one of the base walls includes a recess for a patch for controlling the wearing of the wiping blade.

8. A connection base according to claim 1 , wherein the connection base is made in one piece using a plastic material.

9. A connection base according to claim 1 , wherein the connection base includes first and second lateral skirts, and wherein the resilient arms are disposed within the connection base between the lateral skirts.

10. An adapter configured to be connected to a wiping actuation arm and to a connection base carrying a wiping blade, the adapter comprising:
a first and a second longitudinal end, wherein the adapter has an elongated longitudinal shape in the same direction as the wiper blade,
wherein the first longitudinal end comprises side parts in a shape of cylindrical axes configured to cooperate with a retaining linear guide of the connection base, the adapter dimensioned for sliding engagement of the adapter with the retaining linear guide,
wherein the second longitudinal end comprises removable attachment complementary means configured to cooperate with the connection base,
wherein said removable attachment complementary means are formed with snapping means, and wherein the snapping means include at least one pin, the at least one pin having a semi-circular shape and protruding downwardly from a planar surface and being positioned laterally inward from laterally outer edges of the planar surface, and wherein the at least one pin is able to cooperate with two resilient arms comprising a shape of a fork, and
wherein the removable complementary means of the second longitudinal end of the adapter has a different shape from the first longitudinal end.

11. An adapter according to claim 10 , wherein the snapping means include two arm-pin pairs.

12. An adapter according to claim 10 , further comprising at least one protrusion preventing the assembling of the adapter with said connection base when the removable attachment complementary means are incorrectly aligned.

13. The adapter according to claim 12 , wherein the at least one protrusion is a half-disk with a semi-circular shape, extending downward from a bottom of the adapter.

14. The adapter according to claim 10 , further comprising a set of walls forming a square, protruding downwardly from the planar surface, configured to cooperate with a matching form of the connection base.

15. A mechanical connector for a wiper blade for an automobile, comprising:
a connection base according to claim 1 ; and
an adapter comprising:
a first and a second longitudinal end, wherein the adapter has an elongated longitudinal shape in the same direction as the wiper blade,
wherein the first longitudinal end comprises side parts in the shape of cylindrical axes configured to cooperate with a retaining linear guide of the connection base, the adapter dimensioned for sliding engagement of the adapter with the retaining linear guide,
wherein the second longitudinal end comprises removable attachment complementary means, distinct from the retaining linear guide, configured to cooperate with the connection base,
wherein said removable attachment complementary means of the adapter are formed with snapping means, and wherein the snapping means include at least one pin able to cooperate with two resilient arms comprising a shape of a fork,
wherein the removable complementary means of the second longitudinal end of the adapter has a different shape from the first longitudinal end of the adapter.

16. A flat wiper blade, comprising a wiping blade supported by a connection base according to claim 1 .

17. A wiping device, comprising a flat wiper blade according to claim 16 and an adapter connected to an actuation arm of a wiping motorized mechanism, the adapter comprising:
a first and a second longitudinal end, wherein the adapter has an elongated longitudinal shape in the same direction as the wiper blade,
wherein the first longitudinal end comprises side parts in the shape of cylindrical axes configured to cooperate with a retaining linear guide of the connection base, the adapter dimensioned for sliding engagement of the adapter with the retaining linear guide,
wherein the second longitudinal end comprises removable attachment complementary means, distinct from the retaining linear guide, configured to cooperate with the connection base,
wherein said removable attachment complementary means of the adapter are formed with snapping means, and wherein the snapping means include at least one pin able to cooperate with two resilient arms comprising a shape of a fork, and
wherein the removable complementary means of the second longitudinal end of the adapter has a different shape from the first longitudinal end of the adapter.
