Description

Technical Field

[0001] The present invention relates to the field of vehicle wipers, and more particularly to a connecting device that enables a wiper blade to be connected to a drive arm.

Background Art

[0002] A wiper system for a vehicle is designed to remove liquids and dirt that may obstruct the driver's view by wiping. These wiper systems generally include a drive arm that performs an angular back-and-forth movement and a long wiper that carries a blade rubber made of an elastic material by itself. The blade rubber rubs the windshield and removes this liquid and dirt by sweeping it from the driver's view.

[0003] The wiper blade is attached to the drive arm by a connection system that includes a connector and an adapter. The connector is a component that is fixed to the wiper blade, generally fixed to the wiper blade rubber. The adapter is a component that intervenes between the drive arm and the connector and is configured to fit into an end piece belonging to the drive arm. The connector and the adapter then provide a joint connection and cooperate to attach the wiper blade to the drive arm, thus forming a device for connecting the wiper blade to the drive arm.

[0004] The joint connection between the connector and the adapter includes at least one transverse axis of pivoting of the connector relative to the adapter, which is also the axis of pivoting of the wiper blade relative to the drive arm. One of the members, for example the connector, generally forms a pivot and has a substantially cylindrical shape that is received within a complementary-shaped housing in the other member, in this example the adapter.

[0005] The adapter is connected to the drive arm via a shaft of the drive arm, which passes through the adapter and through an opening located in the side wall of the adapter. During use of the wiping system, pivoting or slippage may occur between the adapter and the drive arm. Such pivoting or slippage can interfere with the movement of the wiper blade, thus impairing the quality of the sweep across the vehicle's windshield. [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] Therefore, the aim is to avoid such pivoting or slipping between the adapter and the drive arm. To do this, one solution is to create a situation in which the shaft of the drive arm and its receiving opening in the adapter are supported by each other. [Means for solving the problem]

[0007] The present invention, within the scope of this context, proposes an adapter that can provide support between the shaft of a drive arm and a pivot member positioned on the side wall of the adapter, the shaft of the drive arm for this purpose being pushed into the pivot member.

[0008] Accordingly, one subject of the present invention relates to an adapter intended to connect a wiper blade to a drive arm for a vehicle via a connector, having a first lateral wall and a second lateral wall between which an upper wall is positioned, at least one of these lateral walls comprising a pivot member intended to rotate the adapter relative to the connector, the pivot member comprising at least one hole configured to receive a shaft of the drive arm. According to the present invention, the pivot member comprises at least one immobilizing member within the hole that can prevent pivoting between the shaft of the drive arm and the adapter.

[0009] The immobilizing member is, for example, at least one rib protruding into the hole, or a series of blocks or sectors similarly protruding into the hole.

[0010] Therefore, the adapter contributes to connecting the wiper blade to the drive arm via a connector fixed to the wiper blade. The adapter is assembled on this connector by fitting, and the resulting connector can receive the drive arm, which in this case comprises at least one hole configured to receive the shaft of the drive arm.

[0011] The pivot member may, in particular, include a pivot bushing. A hole, advantageously positioned at the center of the pivot bushing, is formed in one of the side walls of the adapter, forming a receiving cylinder formed within the thickness of the side wall, the receiving cylinder having a circular cross-section. The hole has at least one rib that can prevent pivoting between the drive arm shaft and the adapter, the rib allowing the drive arm shaft to be pushed into the pivot member, more specifically into the hole.

[0012] According to one feature of the present invention, the immobilizing member comprises at least one rib formed on a surface defining a hole.

[0013] According to another feature of the present invention, the immobilizing member comprises at least three ribs separated from each other by 120° angular sectors. When the immobilizing member has three ribs, they may be evenly distributed on the surface defining the hole, and then separated by 120° angular sectors. The number of ribs may be a multiple of three. For example, one can envision an adapter according to the present invention having six ribs evenly distributed within the hole, or twelve ribs. What is meant by "within the hole" is that any number of ribs are formed on the surface defining the hole and extend within the thickness of the transverse wall supporting the hole.

[0014] According to another feature of the present invention, at least one rib extends parallel to the axis of a hole configured to receive the shaft of a drive arm. Thus, the rib extends in a direction in which the shaft of the drive arm also extends. This direction is perpendicular to the longitudinal or elongation direction of the adapter. Alternatively, the rib may extend laterally with respect to the axis of the hole, or in a spiral manner wound around the axis of the hole.

[0015] According to one feature, the transverse wall supporting the hole is defined by an inner and outer surface, and at least one of the ribs extends continuously from the inner surface to the outer surface of the transverse wall. Thus, at least one rib extends across the entire thickness of the transverse wall and is defined by the inner surface at a first end and by the outer surface at a second end.

[0016] According to one feature, the immobilizing member, in particular at least one rib, protrudes from the surface defining the hole. Thus, the immobilizing member extends into the hole and from the surface defining the hole. It will be understood that this surface defining the hole corresponds to the thickness of the transverse wall as described above. At least one rib protrudes from this wall, i.e., extends beyond this wall and toward the center of the hole. The rib may protrude, for example, 0.05 cm from the wall defining the hole.

[0017] According to one feature of the present invention, the first side wall is provided with a hole configured to receive the shaft of a drive arm, and the second side wall is provided with an orifice aligned with the axis of the hole and having a parallelepiped cross-section. Thus, the adapter comprises two openings aligned along one same axis for receiving the drive arm, a hole positioned on the first side wall, and an orifice positioned on the second side wall. The hole is substantially circular in shape, while the orifice has a parallelepiped cross-section. Since the drive arm passes through the adapter, it passes through both the hole and the orifice.

[0018] The present invention also relates to a vehicle connection device intended to connect a wiper blade to a drive arm, comprising at least one connector configured to be fixed to the wiper blade, and at least one adapter as described above.

[0019] According to one feature, the connector includes a bearing that receives a pivot member. This bearing contributes to the pivoting function, and the adapter's pivot bushing is configured to mate into the connector's bearing in a male-female assembly.

[0020] According to another feature of the present invention, the connector comprises a ring protruding from the side of the connector, the ring being housed within an orifice in the second transverse wall of the adapter. Similar to pivot bushings and bearings, the ring is intended to fit into the orifice in the second transverse wall of the adapter within the male-female assembly so as to contribute to the adapter and connector performing a pivoting function relative to one another.

[0021] Therefore, it will be understood that the present invention prevents any rotation between the hole and the drive arm shaft, and the pivoting required for the precise operation of the sweeping operation is performed by a pivot member that allows the adapter to pivot relative to the connector.

[0022] The present invention further relates to a wiper equipped with such an adapter or connecting device. With respect to a wiper blade equipped with such an adapter, the present invention may envision a package that supports or receives the wiper blade and such adapter, whether or not the adapter is assembled together with the wiper blade.

[0023] The present invention further relates to a wiping system comprising a drive arm supporting a wiper blade as described above, wherein the wiper blade is connected to the drive arm by a connecting device, and the adapter is immobilized with respect to rotational and translational motion relative to the drive arm by an immobilizing member, and the adapter is mounted with the ability to pivot with respect to the connector, at least via a pivot member. What is meant by "immobilized with respect to rotational and translational motion" is that the wiper blade remains immobile with respect to the drive arm, i.e., rotation around the axis of the drive arm's shaft and translational motion along this axis are prevented as long as a force of less than 30 Nm is applied translationally between the wiper blade and the drive arm. This then avoids any slippage during operation between the drive arm's shaft and the adapter. Thus, the force required to guide the adapter onto the arm's shaft when mounting the wiper blade can be considered to be between 10 Nm and 30 Nm.

[0024] According to one feature of this wiping system, the drive arm is provided with a locking member that contributes to fixing the drive arm to a connector, the locking member extending at least partially perpendicular to one of the lateral walls of the drive arm and having at least one bent edge, with some play provided, the play being measured between the bent edge of the locking member and the first lateral wall of the adapter, and such play is non-zero.

[0025] The locking member extends perpendicular to one of the lateral walls of the drive arm, that is, substantially perpendicular to the longitudinal or extensional direction of the drive arm. The locking member has a bent edge at one of its ends that is located away from the drive arm. The locking member is intended to cover the coupling device, and the bent edge faces the second lateral wall of the adapter, the latter and the drive arm are positioned side by side.

[0026] There is a clearance measured between the bent edge of the fastening member and the first transverse wall of the adapter that supports the hole with the immobilizing member. According to the present invention, this clearance is a non-zero value. Such a clearance contributes to preventing pivoting between the adapter and the drive arm.

[0027] Further features, details, and advantages of the present invention will become more clearly apparent by reading, on the one hand, the following description and, on the other hand, the exemplary embodiments provided by way of non-limiting examples with reference to the following attached drawings.

Modes for Carrying Out the Invention

[0029] In the figures, elements common to several figures retain the same reference numerals.

[0030] In the following detailed description, the terms “longitudinal,” “lateral,” and “vertical” refer to the orientation of the adapter according to the present invention. The longitudinal direction corresponds to the main extension direction of the adapter, and this longitudinal direction is parallel to the longitudinal axis L of the coordinate system L, V, T shown in the figure. The lateral direction corresponds to the direction in which the shaft of the drive arm extends, and this lateral direction is parallel to the transverse axis T of the coordinate system L, V, T, and this transverse axis T is perpendicular to the longitudinal axis L. Finally, the vertical direction corresponds to the direction parallel to the vertical axis V of the coordinate system L, V, T, and this vertical axis V is perpendicular to the longitudinal axis L and the transverse axis T.

[0031] Furthermore, the references to "down" and "up" in relation to the elements of the adapter mean that, relative to the distance of these elements from the locking member of the drive arm, the upper end of such an element corresponds to the end positioned near the locking member, and the lower end corresponds to the end positioned away from the locking member.

[0032] Accordingly, Figure 1 shows a wiping system 10 according to the present invention, comprising a wiper blade 12 and a drive arm 14 for driving the wiper blade 12. The wiper blade 12 comprises a longitudinal body 16, a wiper blade rubber 18, which is generally made of rubber, and at least one spine (not shown) that reinforces the wiper blade rubber 18 and encourages it to press against the vehicle windshield.

[0033] The schematicly shown wiper blade 12 further comprises end fittings or clips 22 for attaching the wiper blade rubber 18 and spine to the longitudinal body 16, the end fittings 22 being located at each of the longitudinal ends of the longitudinal body 16.

[0034] The wiper blade 12 substantially supports the connecting device 1 according to the present invention in its center. This connecting device 1 comprises, in particular, a connector 24 and an adapter 25 according to the present invention.

[0035] The adapter 25 contributes to connecting the connector 24 to the drive arm 14. The adapter 25 is mounted on the connector 24 so as to maintain a degree of freedom of pivoting around an articulation axis Y, which is a horizontal axis substantially perpendicular to the longitudinal axis of the wiper blade 12. This degree of freedom allows the wiper blade 12 to pivot relative to the drive arm 14 and thus to follow the curvature of the windshield as the wiper blade 12 moves.

[0036] The drive arm 14 is driven by a motor (not shown) to follow an angled back-and-forth motion that allows it to remove water and, if any, other undesirable elements covering the windshield. The adapter 25 provides a connection between the wiper blade 12 and the drive arm 14. More specifically, they contribute to connecting a head or yoke 28 that belongs to the drive arm 14 and can be formed integrally with the drive arm 14 or attached and fixed to its rod.

[0037] The yoke 28 has an elongated shape in an overall direction substantially parallel to the longitudinal direction of the wiper blade 12. The yoke 28 extends at one of its longitudinal ends by a connecting portion 30 for connecting to the rod of the drive arm 14.

[0038] Figures 2 and 3 are perspective views of the adapter 25 of Figure 1, viewed from the opposite side. The adapter 25 extends mainly in the longitudinal direction and has a substantially U-shaped cross-section. The adapter 25 has a body 254 comprising a first lateral wall 251 and a second lateral wall 252, these walls being substantially parallel and spaced apart from each other. These walls 251, 252 are connected to each other by an upper wall 250 that is substantially perpendicular to them. The walls 250, 251, 252 of the adapter 25 have a longitudinally elongated shape, between which they define an internal housing 253 intended to accommodate a connector 24.

[0039] At one of its longitudinal ends, the body 254 of the adapter 25 is connected to the head 255, whose vertical and lateral dimensions are greater than those of the body 254 of the adapter 25. Thus, it will be understood that the head 255 extends beyond the longitudinal and lateral planes over which the upper wall 250 extends, and beyond the longitudinal and vertical planes over which the lateral walls 251 and 252 extend. The head 255 is, among other things, a locking mechanism. More specifically, when the wiper blade 12 is assembled with the drive arm 14 via the connector 1 as shown in Figure 1, the head 255 forms an end stop for the yoke 28 of the drive arm 14, thus preventing translational motion of this yoke beyond the body 254 of the adapter 25.

[0040] At the other longitudinal end, the upper wall 250 of the adapter 25 narrows toward a point 257 that extends beyond the body 254. At this other longitudinal end, the body 254 of the adapter 25, more specifically the lateral walls 251 and 252, are continuous in the form of elastically deformable legs 256. These legs 256 may be brought closer to each other by elastic deformation. The legs 256 are substantially symmetrical about a plane of symmetry extending longitudinally and vertically, and are equidistant from the first lateral wall 251 and the second lateral wall 252. Each leg 256 further has a locking portion 456 configured to cooperate with a notch in the yoke 28 of the drive arm 14 to lock the adapter 25 assembly with it, thus forming another locking means.

[0041] The upper wall 250 has a first opening 259, a second opening 359, and a third opening 459, which are aligned longitudinally and open onto the internal housing 253. The third opening 459, located near the leg portion 256, is partially covered by a locking member 85. This locking member 85 comprises, in particular, a flexible tongue 850 and a push button 851. The tongue 850 extends mainly longitudinally and has a fixed end 853 located some distance from the leg portion 256, connected to the transverse walls 251 and 252 by a bridge of material, and a free end 852 that can move near the leg portion 256. The tongue 850 is elastically deformable, and its free end 852 supports the push button 851.

[0042] The first transverse wall 251 includes a pivot member 45 intended to allow the adapter 25 to rotate relative to the connector 24. This pivot member 45 includes a pivot bushing 455. A substantially circular through-hole 451 is formed in the first transverse wall 251, and this hole 451 is configured to receive the shaft 283 of the drive arm 14, as shown in Figures 5 and 7.

[0043] Meanwhile, the second lateral wall 252 has a substantially parallel through-orifice 452 aligned with the axis of the hole 451. The hole 451 and the orifice 452 open into the internal housing 253. When the adapter 25 is assembled with the drive arm 14, the shaft 283 of the drive arm 14 passes through the adapter 25 and through both the pivot member 45, more specifically the hole 451 in the first lateral wall and the orifice 452 in the second lateral wall 252. Although the shaft 283 of the drive arm 14 passes through both the hole 451 and the orifice 452, it contacts the hole 451 but not the orifice 452. The hole 451 and the orifice 452 pass through them and have a pivot axis P of the adapter 25 to the connector 24, and by extension, the wiper blade 12 connected to the adapter 25 to the drive arm 14 connected to the connector 24, as shown in Figure 6.

[0044] According to the present invention, the hole 451 has at least one immobilizing member 450, which can take the form of a rib 453 that can prevent pivotal and translational motion between the shaft 283 of the drive arm 14 and the adapter 25.

[0045] Figures 4 and 5 are schematic diagrams of the hole 451. According to the illustrated embodiment, the hole 451 has three ribs 453, referred to here as 453A, 453B, and 453C, evenly distributed circumferentially and separated from each other by 120° angular sectors. However, the number and position of the ribs provided in the hole 451 may vary depending on the embodiment, and may be, in particular, two or other multiples of three. The first transverse wall 251 supporting the hole 451 is laterally defined by an inner surface 251A and an outer surface 251B, and these surfaces 251A and 251B also define a surface 454 that defines the hole 451. It will be understood that this surface 454 is formed by the thickness of the first transverse wall 251 of the adapter 25. Thus, the hole 451 forms a receiving cylinder, advantageously with a circular cross-section, formed within the thickness of the first transverse wall 251.

[0046] The ribs 453 extend continuously from the inner surface 251A to the outer surface 251B of the associated transverse wall, and thus extend along the entire thickness of the first transverse wall 251. These ribs 453 protrude from the surface 454 and thus extend beyond it. Such protrusion may be, for example, 0.05 centimeters, meaning that the ribs 453 extend 0.05 centimeters beyond the surface 454. The ribs 453 extend parallel to the axis of the hole 451 configured to receive the shaft 283 of the drive arm 14, as seen in Figure 4. Because the ribs 453 protrude from the surface 454, when the shaft 283 of the drive arm 14 is inserted into the hole 451, the shaft 283 does not come into contact with this surface 454 except for the ribs 453. Therefore, it will be understood that, except for the rib 453 on which the shaft 283 of the drive arm 14 is located, there is a space 457 between the surface 454 and the shaft 283, which is shown in Figure 5.

[0047] When the shaft 283 of the drive arm 14 is inserted translationally into the hole 451 in the first transverse wall 251, the ribs 453 deform. These form contact surfaces or anchor points for the shaft 283, thus allowing the shaft to be compressed into the adapter 25. This anchor point and compression fit contribute to the formation of a support, which helps prevent the shaft 283 of the drive arm 14 from pivoting or sliding and its respective translational motion relative to the adapter 25, as long as the force generated in this translational motion is less than 30 Nm, which is higher than the load associated with the operation of the wiper system.

[0048] Figure 6 shows a connection device 1 according to the present invention, which is intended to connect a wiper blade 12 to a drive arm 14. The connection device 1 comprises an adapter 25 that can be connected to the drive arm 14 and a connector 24 that can be fixed to the wiper blade 12. The wiper blade 12 is inserted into a housing 244 of the connector 24, which is designed to receive it.

[0049] The connector 24 and adapter 25 are mated together to form a separable entity corresponding to the connector 1. Thus, the elements of the connector 1 will be understood to be assembled in a detachable manner, i.e., they can be associated and separated in sequence without damage. For this purpose, the connector 24 has a bearing 241 on one of its lateral sides facing the first lateral wall 251 that receives a pivot member 45, more specifically a pivot bushing 455. Thus, this bearing 241 corresponds to a lateral hole in the connector 24. Thus, the pivot bushing 455, which protrudes into the inner surface 251A of the first lateral wall 251, is pressed into the bearing 241 of the male-female assembly.

[0050] On the opposite side from the side supporting the bearing 241, the connector 24 has a ring 242 which similarly contributes to assembling the connector 24 with the adapter 25. This ring 242, corresponding to the shoulder, protrudes from the side of the connector 24. The ring 242, like the male and female assembly, is housed in the orifice 452 of the second lateral wall 252 of the adapter 25.

[0051] Therefore, the adapter 25 and the connector 24 can pivot through the cooperation of these elements, namely, the cooperation of the pivot bushing 455 of the pivot member 45 in the case of the adapter 25, and the cooperation of the bearing 241 and the ring 242 in the case of the connector 24. Thus, in the wiping system 10 according to the present invention, when the wiper blade 12 is connected to the drive arm 14 via the connecting device 1, the adapter 25 is implemented with the ability to pivot relative to the connector 24. Effectively, the pivot member 45 functions as a pivot connection. Thus, when the connector 24 is fixed to the wiper blade 12, for example by crimping, the wiper blade 12 can pivot relative to the adapter 25 and the drive arm 14 to which the adapter 25 is connected. As a result, the wiper blade 12 can perfectly follow the curved surface of the windshield of the vehicle to which it is mounted during its movement.

[0052] Conversely, pivoting or sliding of the drive arm 14 relative to the adapter 25 is prevented by the immobilizing member 450, in particular by at least one rib 453, which pushes the shaft 283 of the drive arm 14 into the pivot member 45, more specifically into the hole 451 in the first transverse wall 251. During the operation of the wiping system 10 as shown in Figure 1, a support effect occurs, thus preventing the pivoting or sliding described above.

[0053] Figure 7 shows a connecting device 1 equipped with an adapter 25 according to the present invention, which is assembled together with a drive arm 14.

[0054] The drive arm 14 includes a yoke 28 formed at the end of the drive arm 14. This yoke 28 consists of an upper wall 281 that extends in the longitudinal direction of the drive arm 14, in particular, and is adjacent to two lateral walls 282 perpendicular thereto. To assemble the adapter 25, more generally the connector 1, with the drive arm 14, the latter has a locking member 284. Such a locking member 284 takes the form of a tab that extends perpendicular to one of the lateral walls 282 of the drive arm 14, and in particular extends in a plane that coincides with the extended plane of the upper wall 281 of the yoke 28. The locking member 284 has a bent edge 285 at one end of the tab that is located away from the drive arm 14. This bent edge extends in a plane that is generally parallel to the extended plane of at least one of the lateral walls 282 of the yoke 28.

[0055] When the connecting device 1, which includes an adapter 25 and a connector 24, is associated with the drive arm 14, the connecting device 1 is pivoted by approximately 45° such that the shaft 283 is forced laterally into the hole 451 of the adapter 25, which is then aligned longitudinally by pivoting the wiper blade using the pivot member of the adapter.

[0056] Next, the shaft 283 of the drive arm 14 passes through the connecting device 1, particularly the adapter 25, that is, from its first transverse wall 251 to its second transverse wall 252, extending beyond the longitudinally perpendicular plane over which these transverse walls 251 and 252 extend. The locking member 284 grips the connecting device 1, thus fixing it to the wiper blade 12. To achieve this, the bent edge 285 faces the second transverse wall 252 of the adapter 25, and the adapter 25 and the drive arm 14 are aligned laterally.

[0057] When the adapter 25 and the drive arm 14 are thus associated, the first distance between the first lateral wall 251 and the second lateral wall 252 is shorter than the second distance between the lateral wall 282 of the drive arm 14 from which the locking member 284 extends and the inverted edge 285 of the locking member 284. Thus, there is a clearance, and it will be understood that clearance B is between the inverted edge 285 of the locking member 284 and the first lateral wall 251 of the adapter 25 that supports the hole 451. According to the present invention, this clearance B is non-zero. Such a clearance is brought about by the interference fit of the shaft 283 of the drive arm in the hole 451 that supports the member 450 for immobilization on the adapter 25, and therefore does not affect the mechanical connection between the adapter 25 and the drive arm 14.

[0058] Accordingly, the present invention proposes an adapter having at least one rib, the rib providing support for the shaft of the drive arm, and thus preventing pivotal and translational motion of the drive arm relative to the adapter.

[0059] However, the present invention is not limited to the means and configurations described and illustrated herein, but extends to all equivalent means and configurations, as well as any technically functional combination of such means.
