Abstract

The invention relates to a connection base (1) for carrying a wiping blade and to be attached to an adapter (5) that can be connected to an actuation arm for forming with said adapter (5) a mechanical connector for a wiper blade for an automobile, the adapter (5) having an elongated shape with first (7) and second (9) ends, characterised in that it comprises a retaining linear guide (27, 29) for the first end (7) of the adapter and removable attachment means (13) of the second end (9) supported on the one hand by the adapter and on the other hand by the base (1). The invention also relates to a conform adapter (5), to a mechanical connector formed by the adapter and the connection base, to a planar wiper blade and to a wiping device.

Claims

1. A connection base configured to support a wiping blade and to be attached to an adapter, wherein the adapter is configured to be connected to an actuation arm to form, with the adapter, a mechanical connector for a wiper blade for an automobile, wherein the adapter comprises an elongated shape, and includes:

a first and a second end;

a retaining linear guide for the first end of the adapter; and

removable attachment complementary means of the second end supported on the one hand by the adapter and on the other hand by said connection base.

2. A connection base according to claim 1, wherein the retaining linear guide is provided by base walls arranged to form two insertion channels configured to receive associated side parts of the first end of the adapter.

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

4. A connection base according to claim 1, wherein said removable attachment complementary means are formed by snapping means.

5. A connection base according to claim 4, wherein the snapping means include two resilient arms comprising a shape of a fork and configured to receive an associated pin.

6. A connection base according to claim 5, wherein the snapping means include two arm-pin pairs.

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

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

9. A connection base according to claim 2, wherein one of the base walls includes a recess for a patch for controlling the wearing of the wiping blade.

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

16. A mechanical connector for a wiper blade for an automobile, comprising:

a base according to claim 1; and

an adapter according to claim 11.

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

11. An adapter configured to be connected on the one hand to a wiping actuation arm and on the other hand to a connection base carrying a wiping blade, wherein the adapter and the connection base form a mechanical connector for a wiper blade for an automobile, the adapter comprising an elongated shape, and including:

a first and a second end,

wherein the first end comprises axes configured to cooperate with a retaining linear guide of the connection base; and

removable attachment complementary means of the second end, supported on the one hand by the adapter and the other hand by said base.

12. An adapter according to claim 11, wherein said removable attachment complementary means are formed with snapping means.

13. An adapter according to claim 12, wherein the snapping means include at least one pin able to cooperate with two resilient arms comprising a shape of a fork.

14. An adapter according to claim 13, wherein the snapping means include two arm-pin pairs.

15. An adapter according to claim 11, 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.

18. A wiping device, comprising a wiper blade according to claim 17 and an adapter according to claim 11 connected to an actuation arm of a wiping motorized mechanism.
