Abstract

The wiper blade has a wiper blade upper surface (3.2) with wiper blade adapter (4), where receptacle (2) of a wiper arm (1) is attached on the wiper blade adapter. The wiper blade adapter is formed with two bushes (16). An independent claim is included for a wiper blade or wiper arm connection for use in between a wiper blade and a wiper arm of a windshield wiper system for vehicles.

Description

The The invention relates to a wiper blade according to the preamble Claim 1 and on a wiper blade / wiper arm connection, d. H. to a connection between a wiper blade and a wiper arm a windshield wiper system according to the preamble of claim 12th

Wiper blades for windscreen wiper systems are known in various designs. Wiper blades with a wiper blade adapter are also known ( EP 1 403 156 A1 ), which can be inserted into a recess provided on the wiper arm and open toward the free end of the wiper arm and locked there by latching. For latching, at least one resilient detent is provided on an adapter part, which can be pushed forward in a joining direction into the wiper arm-side receptacle with its rear side and then engages behind a wiper arm formed on the wiper arm.

at a well-known wiper blade design is the resilient detent provided for at the top of the wiper blade adapter the locking in a counter-locking opening at the top of the wiper arm. This has u. a. the advantage of that the proper locking of the wiper blade adapter on the wiper arm also optically easily verifiable and Furthermore, a convenient release of the locking connection and thus the wiper blade from the wiper arm is possible. The rest is thereby formed by a projection on a spring or latching tongue, the over the back of the wiper blade adapter part protrudes.

at another known wiper blade design are on two opposite each other and one longitudinal side the wiper blade adjacent sides of the wiper blade adapter resilient detents provided, in turn, from projections to turn over the back side of the wiper blade adapter or locking tongues are formed. As counterpatches serve openings, in the legs of the U-shaped in the recording Wiper arm are provided.

adversely is in these known wiper blade versions u. al., that all notches with mounted wiper blade light accessible areas, so that it becomes one unwanted release of the locking connection, for example in a car wash by local functional elements, for example can come through cleaning rollers.

Wiper blade designs are also known ( WO 2007/033827 ), in which at the rear end of the wiper blade adapter in each case a detent is provided which engages after insertion of the wiper blade adapter into the receptacle on counter-detents, which are formed on the underside of the wiper arm. The disadvantage here is, inter alia, that the wiper blade is secured to the wiper arm only by a single catch or latch or spring tongue and that it is a defect or failure of this single catch or latching tongue, for example, by aging, damage, even by improper use and / or by improper mounting can lead to a detachment of the wiper blade from the wiper arm.

task The invention is to show a wiper blade, which under Maintaining a simplified assembly by inserting the wiper blade adapter in a wischarmseitige recording a reliable and ensures secure connection with the wiper arm. to Solution to this problem is a wiper blade according to the Claim 1 is formed. A wiper blade / wiper arm connection is the subject of claim 12.

The Wiper blade according to the invention has at least two each cooperating with independent counter-detents on the wiper arm resilient detents, at least a first resilient detent at the top of the wiper blade adapter for cooperation with a Gegenrast at the top of the wiper arm and at least one second resilient latch for cooperation with a counter-locking on the Bottom of the wiper arm.

In the figures is 1 a wiper arm of an otherwise not shown windshield wiper system for vehicle windshields. The wiper arm 1 is connected at its not shown in the figures end in a conventional manner via a Wischarmgelenk with a wiper shaft, which by a windshield wiper drive for a reciprocating pivotal movement of the wiper arm 1 reversing driven. On the wiper blade side Wischarmende 1.1 is the wiper arm 1 with a recording 2 for releasable attachment of a flat wiper blade 3 formed, using a two-piece wiper blade adapter 4 , This consists inter alia of the wischarmseitigen adapter part 4.1 which is in the recording 2 from the free end of the wiper arm 1 forth in a joining direction A and with its rear end in advance and insertable in this recording 2 in the manner described in more detail below can be locked by latching. The wiper blade adapter 4 continues to consist of the adapter part 4.2 , which is attached to the wiper blade top in the wiper blade center or about in the wiper blade center.

The wiper blade 3 is executed in the illustrated embodiment as a flat wiper blade and forms on its wiper blade underside the voltage applied during the wiping operation against the vehicle window wiper lip 3.1 , At the wiper blade top 3.2 is the wiper blade 3 shaped like a spoiler at 6. With 5 are two in each wiper blade longitudinal direction extending flat spring rails referred to.

The two adapter parts 4.1 and 4.2 are about one the adapter part openings 7 and 8th cross-hinge, not shown hinge pin hinged together, so that in a recess 9 of the adapter part 4.1 recorded adapter part 4.2 and thus the wiper blade 3 by a reduced angular contribution compared to the adapter part 4.1 or opposite the wiper arm 1 are pivotable.

To form the free end of the wiper arm 1 open recording 2 is the wiper arm 1 at the wiper blade end 1.1 as one to the Wischarmunterseite and with mounted wiper blade 3 running to this open US profile, with two legs 10 and 11 and a yoke portion connecting the legs 12 at the top of the wiper arm.

How the particular 1 shows, this U-profile sits at least in one to the recording 2 or to the end 1.1 subsequent subsection 1.2 the wiper arm 1 in such a way that in the area of this subsection 1.2 where the wiper arm 1 is cranked in plan view and has a slightly Z-shaped course, to the leg 10 an obliquely extending to this leg portion 10a and then one parallel or approximately parallel to the leg 10 extending leg section 10b connect. In similar form close to the thigh 11 an oblique to this oriented leg portion 11a and a leg section 11b in turn, in the illustrated embodiment parallel or substantially parallel to the leg 11 is oriented. At the yoke section 12 closes a yoke section 12a on, that of the leg sections 10a . 10b . 11a and 11b formed U-profile of the section 1.2 completed. It is understood that the wiper arm 1 at least at the wiper arm end 1.1 and the subsequent subsection 1.2 is integrally made of a suitable material, for example made of metal or steel sheet.

In the field of recording 2 are the two thighs 10 and 11 over a partial length of this recording, each with at least one inwardly directed bend 10.1 respectively. 11.1 provided, in such a way that in the recording 2 in the joining direction A inserted adapter part 4.1 with a section 4.1.1 positive fit in the receptacle 2 is included and in particular also the two bends 10.1 and 11.1 the section 4.1.1 at the wiper blade 3 The rear side of the press-fit side is positively engaged, while another section 4.1.2 of the adapter part 4.1 at the wiper arm 1 attached adapter 4 the opening of the picture 2 also visually appealing closes.

As the 5 - 7 show is the adapter part 4.1 especially in its section 4.1.1 to form the adapter part 4.2 partially receiving opening 9 executed as a U-profile, which to the rear, the section 4.1.2 opposite end of the adapter part 4.1 as well as to the bottom of this adapter part is open. The adapter part 4.1 consists of two leg sections 13 and 14 and a connecting yoke section 15 wherein the leg sections 13 and 14 as well as the yoke section 15 on the front of the adapter part 4.1 in the local section 4.1.2 pass. With mounted adapter 4 lie the leg section 13 the inner surface of the thigh 10 , the thigh section 14 the inner surface of the thigh 11 and the yoke section 15 the inner surface of the yoke section 12 immediately adjacent.

After inserting the adapter part 4.1 in the recording 2 is the adapter part 4.1 secured there by double locking. This is at the top of the adapter part 4.1 the yoke section 15 on a partial length as a spring tongue 15.1 formed at its free end with a over the top of the adapter part 4.1 projecting, in the illustrated embodiment in cross-section square projection or detent 16 is provided. This thus resilient catch 16 is at the recording 2 a counter-ratchet 17 assigned in the form of a latching opening, which is the square cross section of the catch 16 correspondingly also has a square cross-section and in which the catch 16 engaging latching. The spring tongue 15.1 is against their spring action about axes parallel to the top of the adapter part 4.1 resiliently deformable.

To achieve the further locking connection between the wiper blade adapter 3 and the recording 2 is on the back of the adapter part 4.1 the leg section 13 integral with a spring tongue 18 made around axes perpendicular to the top of the adapter part 4.1 is resilient and deformable in continuation of the thigh 13 over the back of the adapter part 4.1 protrudes. At its free ends is the spring tongue 18 with a rest 19 provided in the form of a projection which over the leg portion 14 opposite side of the spring tongue 18 protrudes. When completely in the recording 2 inserted adapter part 4.1 engages behind the springy rest 19 a counter-ratchet 20 , which, in particular from the 3 visible, at the bottom of the oblique to the thigh 10 extending leg portion 10a is formed. For this purpose, the lower edge of the leg portion 10a a stepped course in such a way that it is in the region of the transition between the leg 10 and the leg portion 10a in a common plane with the lower edge of the thigh 10 lies, then to form the Gegenrast 20 or the edge region forming this counter-latching step extends in a step-shaped manner in the direction of the wiper arm upper side and subsequently in a plane with one in comparison to the lower edge of the leg 10 reduced distance from the wiper arm top.

The special advantage of the springy rest 19 and the counter-ratchet 20 formed latching connection is that this latching connection or its elements, and in particular the resilient latch 19 from the rest 16 spatially separated and also in the area of the underside of the wiper arm 1 or the wiper blade adapter 4 and thereby at least largely protected against unwanted loosening, for example by functional elements of a car wash, such. As cleaning rollers and / or brushes, etc. are provided.

To release the wiper blade 3 From the wiper arm, it is necessary in this embodiment of the invention, both notches 16 and 19 or their detent or spring tongues 15.1 respectively. 18 to operate the locking connection between the wiper blade adapter 4 and the wiper arm 1 or the recording 2 to solve.

The 8th - 11 show a wiper blade adapter 4a , in turn, after insertion into the recording 2 the wiper arm 1 locked there twice by latching, by the one with the opening 17 cooperating resilient catch 16 at the top of the adapter part 4a.1 as well as a further springy rest 21 that with a counter-ratchet 22 interacts in the field of recording 2 at the bottom of the wiper arm 1 is formed, of a in a plane transverse or perpendicular to the longitudinal extent L of the recording 2 or to the joining direction A arranged surfaces of the subsection 1.1 facing the end of the bend 11.1 on the thigh 11 ,

The rest 21 consists essentially of a footbridge 23 , with its upper end with the spring tongue 15.1 connected or formed on the spring tongue and the spring tongue 15.1 stands down. At the lower end is at the jetty 23 a laterally wegstehender and with the Gegenrast 22 cooperating latching section 24 provided with the wiper blade adapter 4a the counter-ratchet 22 latching behind.

In the illustrated embodiment, the web is 23 designed like a fork, with a web section 23.1 that with the spring tongue 15.1 is connected and with another shortened bridge section 23.2 who is in or on a tour 25 of the adapter part 4a.1 is guided to between the rest 21 and the counter-ratchet 22 acting forces reliably on the adapter part 4a.1 to transfer and in particular the section 23.1 and the spring tongue 15.1 to relieve from such forces.

Unlocking the rest 21 and the counter-ratchet 22 formed latching connection thus takes place by moving the catch 21 perpendicular or approximately perpendicular to the top of the adapter part 4a.1 down, against the spring action of the spring tongue 15.1 around axes parallel to the top of the adapter part 4a.1 is resilient deformable. The resting section 24 is at its the front of the adapter part 4a.1 bevelled side slanted so that when inserting the wiper blade adapter 4a in the recording 2 the resting section 24 first on the bottom of the bend 11.1 slips on and then at the end of the bend 11.1 behind the counter-ratchet 22 forming surface of the bend 11.1 locked.

The 12 and 13 show a wiper blade adapter 4b with an adapter part 4.1 corresponding adapter part 4b.1 , which in turn in the recording 2 is locked by two locking, through the opening 17 cooperative rest 16 at the top of the adapter part 4b.1 and by one with the counter-lock 22 cooperating resilient catch 26 , This consists essentially of a leg section 14 molded spring tongue 27 extending about axes perpendicular to the top of the adapter part 4b.1 is elastically deformable, and from a molded onto the free end of the spring latching portion 28 who is in the picture 2 mounted wiper blade adapter 4b behind the counter-rest 22 or the surface forming this counter-locking latched.

The resting section 28 is at its the front of the adapter part 4b.1 bevelled side so inclined that it is when inserting the adapter part 4b.1 in the recording 2 initially under elastic deformation of the spring tongue 27 on the edge of the bend 11.1 slips on and then at the end of the bend 11.1 behind the local counter-rest 22 locked.

Unlocking the rest 26 takes place in this embodiment by pivoting the locking portion 28 under elastic deformation of the spring tongue 27 inwardly, ie in an axial direction perpendicular or approximately perpendicular to the leg portion 14 towards the other leg section 13 , To unlock the rest 26 simultaneously with unlocking the rest 16 to reach is at the rest 26 or on an extension of the latching section 28 a control surface formed as an inclined surface 29 provided with a wedge or beveled surface 30 at the free end of the spring tongue 15.1 molded and over the underside of this spring tongue 15.1 downstanding bridge 31 is formed, in such a way that when unlocking the catch 16 , ie when pressing the latch or spring tongue 15.1 down the resting section 28 over the co-operating inclined surfaces 29 and 30 against the action of the spring tongue 26 moved inward and thus by the rest 26 and the counter-ratchet 22 formed locking connection is unlocked.

The wiper blade adapter 4 . 4a and 4b or the adapter parts 4.1 . 4a.1 and 4b.1 such as 4.2 are each preferably molded parts made of a suitable material, such as plastic, with all the above elements, in particular with the notches 16 . 19 . 21 and 26 are made in one piece.

All described embodiments have in common that the latching of the respective wiper blade adapter 4 . 4a or 4b in the recording 2 done twice, and indeed by the rest 16 on the upper side of the wiper arm and through the additional catch 19 . 21 respectively. 26 , each with a counter-detent 20 respectively. 22 cooperates on the Wischarmunterseite, and indeed to achieve a high level of security of attachment of the wiper blade 3 on the wiper arm 1 ,

At the wiper blade adapters 4 and 4b become the resilient catches 16 . 19 and 26 moved during locking and when releasing the locking connection in each case in the axial directions which are oriented perpendicular to each other, ie the detent 16 in an axial direction perpendicular or substantially perpendicular to the upper side of the wiper blade adapter 4 respectively. 4b and the rest 19 respectively. 26 in an axial direction perpendicular or substantially perpendicular to the leg sections 13 and 14 , At the wiper blade adapter 4a the panning of the catches takes place 16 and 21 when latching and releasing the locking connection in a common axial direction and in the same direction.

In the 14 are again in a simplified representation and in section the Wischarmende 1.1 and the recording there 2 with an adapter part used in this recording 4c.1 shown, which in terms of its function and training the adapter parts 4.1 - 4b.1 corresponds and also in addition to in the 14 shown rest 16 which has at least one further catch, which, however, in this figure for the sake of clarity is omitted. The special feature of the adapter part 4c.1 , which in turn together with the adapter part 4.2 the wiper blade adapter 4c for fixing the wiper blade 3 on the wiper arm 1 forms, is that at the rear end of the adapter part 4c.1 at least one elastic tongue 32 is provided, the free end of the wiper arm 1 mounted adapter part 4c.1 resiliently deformed against a contact surface 33 on the wiper arm 1 supports, namely generating a between the adapter part 4c.1 and the wiper arm 1 acting spring force, the adapter part 4c.1 in a direction B biased against the joining direction A. As a result, during manual, ie intentional release of the locking connection, the removal of the wiper blade 3 from the wiper arm 1 much easier, and in particular the fact that the manual release of the locking connection by the spring action of the tongue 32 the adapter part 4c.1 as far postponed that a renewed automatic locking of the detents 16 . 19 . 21 and 26 not possible.

To remove the wiper blade 3 from the wiper arm 1 Thus, it is only necessary initially to manually release the locking connection. Thereafter, the wiper blade adapter without further actuation of the detents 16 . 19 . 21 and 26 from the reception of the wiper arm 1 be led out.

Another significant advantage is that with the of the at least one tongue 32 generated spring force for the function when locking and when releasing the locking connection between the detents 16 . 19 . 21 and 26 and the associated counter-latches 17 . 20 . 22 necessary game in the assembled state of the wiper blade 3 is compensated or ineffective and thus during the wiping operation also noises caused by this game or the movement wiper blade adapter 4c relative to the wiper arm 1 are conditioned, effectively avoided.

The tongue 32 is for example on the adapter part 4c.1 molded or connected to this adapter part element. Basically there is also the option of the tongue 32 form a plurality of parts, for example made of plastic with a spring force generating or supporting spring element made of metal.

It is understood that instead of the tongue 32 Other spring elements may be provided which the spring force between the mounted wiper blade adapter 4c and the wiper arm 1 generate, for example in the form of at least one of the wiper arm 1 provided spring element, for. B. in the form of a spring tongue, which with a corresponding mating surface on the wiper blade adapter 4c cooperates and in turn generates the opposite to the joining direction oriented A spring force.

The The invention has been described above with reference to exemplary embodiments. It is understood that numerous changes as well as modifications possible are, without thereby the inventive idea underlying the invention will leave.
