Description

technical field

[0001] The invention relates to a device for holding a strip of a windscreen wiper blade in a substantially linear position.

[0002] The invention applies particularly advantageously, but not exclusively, to the field of so-called "flat blades" for windscreen wiper blades. Background technique

[0003] Flat blades are unique in that they do not have a bowed structure compared to the straight blades that are currently used in most cases. The new windscreen wiper blade still has a flexible wiper strip, but the outer frame for supporting it is replaced by a flexible structure integrally formed directly with the strip.

[0004] The assembly is typically arranged such that, once in contact with the surface to be wiped, the pressure exerted by the blade is substantially constant at each point of the wipe strip. This result is generally obtained by employing a flexible structure that gives the strip considerable curvature when at rest, but elastically deforms in ...

Embodiment Construction

[0032] For clarity, the same references are used to denote the same elements. Similarly, only elements necessary for understanding the invention are shown and are not drawn to scale but schematically.

[0033] figure 1 A flat windscreen wiper blade 100 is shown, which is more particularly designed to equip a car, but which in this case is designed to be coupled with a holding device 1 in order to reduce the volume of the blade. In this first description, the naturally curved shape of the flat blade 100 can be clearly seen.

[0034] In a completely conventional manner, the flat wiper blade 100 is mainly composed of a wiper strip 110 comprising a lip 111 and a spoiler 112, a flexible structure 120 being said strip 110 and a connector 130. Providing support, a connector 130 is securely attached to the flexible structure 120 and allows the blade 100 to be mounted on the end of a drive arm of an associated drive mechanism.

[0035] In this particular embodiment, chosen by way of...
