There has already been proposed a wiper blade adapter device having an adapter base member which is provided to be securely connected to a wiper blade component and having an adapter unit which is provided for releasable coupling to a wiper arm adapter, and wherein the adapter unit is provided to be connected to the adapter base member by means of a locking connection.
The invention is based on a wiper blade adapter device having an adapter base member which is provided to be securely connected to a wiper blade component and having an adapter unit which is provided for releasable coupling to a wiper arm adapter, and wherein the adapter unit is provided to be connected to the adapter base member by means of a locking connection.
It is proposed that the adapter unit comprise at least one locking means for engagement with the adapter base member, which is provided, during assembly with the adapter base member, to be deflected at least partially in the direction of a longitudinal center plane of the adapter unit. It is thereby possible for the at least one locking means to be deflected in a particularly force-saving manner and at the same time to provide a high level of operational reliability. A structural height of the adapter unit can advantageously be kept particularly small. The adapter base member advantageously forms side claws which are provided for engaging around resilient rails of a wiper blade. Preferably, the wiper blade adapter device is part of a wiper blade.
The adapter base member is preferably at least substantially, in a particularly preferred manner completely, formed from a plastics material. The term “at least substantially formed” is in this context, with respect to a volume and/or a mass proportion, intended to be understood to be constructed in particular at a level of more than 50%, preferably more than 80%, in a particularly preferred manner more than 95%. The term “fixedly connected” is intended in this context to be understood in particular to be a non-releasable connection of at least two elements which is provided to be released only by means of an at least partial destruction of at least one component and/or by means of a special tool and/or by means of a technical operator. A “wiper blade component” is in this context intended in particular to be understood to be a component of a wiper blade, such as, in particular, a resilient rail, a wiper strip, a wiper lip and/or a wind deflection element.
A “locking means” is in this context intended to be understood to be in particular a resilient means for producing a locking connection which is provided during assembly from a starting position to be resiliently deflected counter to a resilient force. The locking means is in particular provided, during the assembly with the adapter base member, to be deflected at least partially in the direction of a longitudinal center plane of the adapter unit counter to a resilient force. In particular the locking means is provided, during assembly with the adapter base member, to be deflected at least partially in the direction toward the longitudinal center plane of the adapter unit counter to a resilient force. Preferably, the locking means moves when an end assembly position is reached back into the starting position by means of the resilient force. The term “adapter unit” in this context is in particular intended to be understood to be a unit which is provided to provide a coupling region for a coupling and/or contacting with a wiper arm adapter. The term “wiper arm adapter” is in this context intended in particular to be understood to be an adapter which has a contact region with a wiper arm component and which is connected to the wiper arm component in a non-releasable manner and which is provided to provide a coupling region of the wiper arm component for a coupling and/or a contacting with a wiper blade adapter. Advantageously, the wiper arm adapter forms an end region of a wiper rod. In a further advantageous manner, the wiper arm adapter is constructed integrally with the wiper rod. The term “integrally” is intended in particular to be understood to be connected in a materially integral manner, such as, for example, by means of a welding process and/or adhesive bonding process, etcetera, and in a particularly advantageous manner formed on, such as, by means of production from a cast and/or by means of production in a single or multi-component injection-molding method.
The term “in the direction of a longitudinal center plane” is intended in this context to be understood in particular to mean that a direction component of a movement extends perpendicularly to the longitudinal center plane. The term “longitudinal center plane” is intended in this context in particular to be understood to be a notional plane which extends perpendicularly to a wiping direction and which extends through a geometric center point and/or a center of gravity of the adapter base member. The wiping direction extends at least substantially parallel with a deflection direction of the at least one locking means. In particular, the longitudinal center plane is located at least substantially perpendicularly to a surface which is intended to be wiped. The term “at least substantially parallel or perpendicular” is intended in this context to be understood in particular to be a deviation of less than 30°, preferably less than 10° and in a particularly preferred manner less than 5°. In particular, the longitudinal center plane extends in a longitudinal direction of the adapter base member. The term “longitudinal direction” of an object is in this instance intended in particular to be a direction which extends parallel with a longest edge of a smallest geometrical cuboid which the object still completely surrounds. The wiping direction extends in particular perpendicularly to the longitudinal direction and parallel with the surface which is intended to be wiped. The term “provided” is in particular intended to be understood to be specially configured and/or equipped. The fact that an object is provided for a specific function is intended in particular to be understood to mean that the object performs and/or carries out this specific function in at least one application and/or operating state.
In another embodiment of the invention, it is proposed that the adapter unit comprise at least one additional locking means for engagement with the adapter base member which is provided, during assembly with the adapter base member, to be deflected at least partially in the direction of the at least one locking means. A particularly reliable securing between the adapter unit and the adapter base member can thereby be achieved. Preferably, the at least one additional locking means is provided, during assembly with the adapter base member, to be at least partially deflected in the direction of the at least one locking means counter to a resilient force. In particular, the locking means and the additional locking means are provided to be moved toward each other counter to a resilient force when assembled.
Furthermore, it is proposed that the at least one locking means and the at least one additional locking means each comprise an abutment face for abutment against the wiper arm adapter which in a non-deflected state have a spacing with respect to each other which at least substantially corresponds to a width of the wiper arm adapter. The term “at least substantially correspond” is intended in this context to be understood to mean in particular with a deviation of less than 5%, preferably less than 1%.
It is thereby possible to construct a coupling region for the wiper arm adapter in a particularly compact and stable manner. An operational reliability can advantageously be increased since the wiper arm adapter reliably blocks an undesired deflection of the at least one locking means. It is thereby possible for the at least one locking means to be constructed in a particularly advantageous manner with a high level of flexibility for a particularly simple assembly, wherein at the same time operational reliability can be increased. A construction height of the wiper blade adapter device can advantageously be kept small.
It is further proposed that the at least one locking means be provided to move into lateral abutment with the wiper arm adapter during assembly. It is thereby possible to achieve a particularly stable receiving of the wiper arm adapter. The term “lateral abutment” is intended in this context in particular to be understood to be a direct abutment which forms at least one positive-locking connection in the wiping direction.
It is further proposed that the at least one locking means and the at least one additional locking means define a receiving space for positive-locking receiving of the wiper arm adapter. It is thereby possible for one of the wiper arm adapters to be received in a particularly simple manner and at the same time for a reliable securing of the locking connection to be achieved. The term “define” is intended in this context to mean in particular delimit at least at two opposing sides.
It is further proposed that the adapter unit comprise at least one side wall which is provided to cover the at least one locking means at least in one wiping direction. The at least one locking means can thereby advantageously be protected from weather influences. Furthermore, particularly good aerodynamics can be achieved. In addition, a high level of aesthetics of the wiper blade adapter device can be achieved.
In addition, it is proposed that the abutment faces define relative to a wiping direction an angle of at least substantially 45°. The adapter unit can thereby advantageously be constructed in a particularly compact manner. Furthermore, a wiper arm adapter which is positioned obliquely relative to the surface to be wiped can be received in a particularly secure manner.
There is further proposed a system having a wiper blade adapter device according to the invention and having a wiper arm adapter which is provided to block a deflection of the at least one locking means in an assembled state. It is thereby possible to achieve a particularly reliable wiper operation, in particular even at high travel speeds and/or with a dirty or iced vehicle windshield.
There is further proposed a method for assembling a wiper blade adapter device according to the invention with a wiper arm adapter, wherein at least one locking means of an adapter unit of the wiper blade adapter device is deflected during the assembly in the direction of a longitudinal center plane of the adapter unit. A particularly simple and reliable assembly of the wiper blade adapter device with the wiper arm adapter can thereby be achieved. Advantageously, the at least one locking means is blocked after assembly in the direction of the longitudinal center plane by the wiper arm adapter.
The wiper blade adapter device according to the invention is not intended in this instance to be limited to the application and embodiment described above. In particular, the wiper blade adapter device according to the invention in order to carry out an operating method described herein may have a number of individual elements, components and units which differs from a number mentioned herein.

The wiper arm 36 and the wiper blade 32 which is mounted thereon can be driven in an oscillating manner in a pivot movement over the vehicle pane 34. In a wiping operation, a wiper lip 42 of the wiper blade 32 passes over the vehicle pane 34. The wiper blade 32 has a first wind deflection element 44. The first wind deflection element 44 is provided for deflecting travel wind and for producing a pressing force of the wiper blade 32 in the direction of the vehicle pane 34. The first wind deflection element 44 extends almost over half of an entire length extent of the wiper blade 32. The wiper blade 32 has a second wind deflection element 46. The second wind deflection element 46 is constructed separately from the first wind deflection element 44. The first wind deflection element 44 and the second wind deflection element 46 are constructed in a mirror-symmetrical manner with respect to each other. The second wind deflection element 46 is provided for deflecting travel wind and for producing a pressing force of the wiper blade 32 in the direction of the vehicle pane 34. The second wind deflection element 46 extends practically over half of the entire length extent of the wiper blade 32. The wiper blade 32 has two end caps 48, 50. The end caps 48, 50 are arranged at opposing free ends of the wiper blade 32. The end caps 48, 50 terminate the wiper blade 32 in a longitudinal direction 52. The longitudinal direction 52 extends in a mounted state at least substantially parallel with a main length extent direction of the wiper blade 32.
The wiper blade adapter device comprises an adapter unit 14. The adapter unit 14 is provided for releasable coupling with the wiper arm adapter 16. The wiper arm adapter 16 is provided for introduction into the adapter unit 14.

As shown in
The locking means 18 is provided during assembly with the adapter base member 10 to be deflected in the direction of a longitudinal center plane 22 of the adapter unit 14. The additional locking means 20 is provided, during assembly with the adapter base member 10, to be deflected in the direction of a longitudinal center plane 22 of the adapter unit 14. The longitudinal center plane 22 is a notional plane which extends perpendicularly to the wiping direction 64 and which extends through a center of gravity 90 of the adapter base member 10.
The additional locking means 20 is provided, during assembly with the adapter base member 10, to be deflected in the direction of the locking means 18. More specifically, the additional locking means 20 is provided, during assembly with the adapter base member 10, to be deflected in the direction of the locking means 18 counter to a resilient force. The resilient force is produced by a material deformation as a result of the deflection of the respective locking means 18, 20. The resilient force acts counter to the deflection of the respective locking means 18, 20. The locking means 18 and the additional locking means 20 are consequently provided during assembly to be moved toward each other counter to a resilient force.
As shown in
The locking means 18 and the additional locking means 20 comprise in each case an abutment face 24, 26 for abutment on the wiper arm adapter 16. The abutment faces 24, 26 have in a non-deflected state a spacing 28 with respect to each other which corresponds to a width 30 of the wiper arm adapter 16. The abutment faces 24, 26 define relative to the wiping direction 64 an angle of at least substantially 45°. The locking means 18 is provided during assembly to move into lateral abutment with the wiper arm adapter 16. The additional locking means 20 is provided during assembly to move into lateral abutment with the wiper arm adapter 16. The locking means 18 and the additional locking means 20 define a receiving space 78 for receiving the wiper arm adapter 16 in a positive-locking manner.
The locking means 18 and the additional locking means 20 have in each case a locking recess 86, 88. The locking recess 86 of the locking means 18 is open in a direction facing away from the longitudinal center plane 22. The locking recess 86 is provided for partially receiving the deflection means 70. The locking recess 88 of the additional locking means 20 extends completely through the additional locking means 20 in the wiping direction. The locking recess 88 is provided for partially receiving the deflection means 72.
As further shown in
The wiper blade adapter device forms a system with the wiper arm adapter 16, wherein a deflection of the locking means 18 in an assembled state is blocked by the wiper arm adapter 16. In the system, a deflection of the additional locking means 20 in the assembled state is also blocked by the wiper arm adapter 16.
The assembly operation of the adapter unit 14 with the adapter base member 10 and the wiper arm adapter 16 is explained in greater detail below. The adapter base member 10 is already securely connected to the wiper blade component 12. The adapter unit 14 is guided in a vertical direction 92 on the adapter base member 10. The vertical direction 92 is perpendicular to the wiping direction 64 and perpendicular to the longitudinal direction 52. The vertical direction 92 faces in an operating state in the direction of the vehicle pane 34.
The locking means 18, 20 move into abutment with the deflection means 70, 72 and are deflected by them in such a manner that they move toward each other from a starting position counter to a resilient force. In an end position, the locking means 18, 20 move resiliently back into the starting position and engage behind the deflection means 70, 72. Finally, the wiper arm adapter 16 is guided between the locking means 18, 20. The wiper arm adapter 16 moves in this instance into abutment with the locking means 18, 20. In an end assembly position, the locking means 18 and the additional locking means 20 are blocked in the direction of the longitudinal center plane 22 by the wiper arm adapter 16.
