Description
State of the art
[0001] A wiper blade device has already been proposed, comprising at least one bracket element and at least one wind deflector element, which is intended for mounting on the at least one bracket element, and at least one holding unit, which is intended for a positive connection of the at least one bracket element with the at least one wind deflector element and which includes at least one holding element that can be guided into a final assembly position along a longitudinal direction of the wiper blade. Disclosure of the invention
[0002] The invention relates to a wiper blade device with at least one bracket element and with at least one wind deflector element, which is provided for mounting on the at least one bracket element, and with at least one holding unit, which is provided for a positive locking connection of the at least one bracket element with the at least one wind deflector element and which comprises at least one holding element that can be guided along a longitudinal direction of the wiper blade into a final assembly position.
[0003] It is proposed that the at least one holding unit shall include at least one locking element which is designed to lock the at least one bracket element with the at least one wind deflector element along the longitudinal direction of the wiper blade.
[0004] In this context, a bracket element shall be understood to mean, in particular, an element designed to receive at least one intermediate bracket and / or at least one claw bracket, wherein the at least one intermediate bracket and / or the at least one claw bracket is designed to support a suspended wiper blade. In this context, a "wiper blade" shall be understood to mean, in particular, a blade designed to wipe a vehicle window. Preferably, the wiper blade is made of a rubber material. In particular, the wiper blade has a wiping lip designed to make contact with the vehicle window.In this context, a "wind deflector element" is understood to mean, in particular, an element designed to deflect airflow or wind acting on the wiper blade assembly and / or to press the wiper blade assembly against a surface to be wiped. Preferably, the wind deflector element consists at least partially of rubber and / or of a partially elastic plastic. Preferably, the wind deflector element has at least one concave frontal surface. The wind deflector element differs, in particular, from an end cap, a wiper lip, and / or a wiper blade adapter. Advantageously, the wind deflector element extends over at least a large part of the longitudinal extent of the wiper blade assembly in an operating state.
[0005] The design of the wiper blade device according to the invention makes it possible to achieve a wiper blade device that is easy to assemble.
[0006] Furthermore, it is proposed that at least one retaining unit has at least one additional retaining element that can be guided into a final assembly position along a longitudinal direction of the wiper blade. This allows the wind deflector element to be held on the bracket element with a particularly high degree of security and strength.
[0007] It is further proposed that the wind deflector element include at least one retaining element. This allows the retaining unit to be at least partially integral with the wind deflector element, thus reducing the number of separate wiper blade units. Furthermore, this enables particularly simple mounting of the wind deflector element to the bracket element. Preferably, the at least one retaining element is integral with the wind deflector element.
[0008] Furthermore, it is proposed that the at least one bracket element has at least one bracket designed to at least partially overlap the at least one retaining element when assembled. This allows for a particularly simple design of the bracket element for holding the retaining element. In this context, a "bracket" is understood to mean, in particular, a beam-shaped element that spans a gap.
[0009] It is further proposed that the wind deflector element include at least one locking element. This allows the retaining unit to be at least partially integral with the wind deflector element, thus reducing the number of separate wiper blade units. Furthermore, a particularly simple assembly movement for locking the wind deflector element to the bracket element can be achieved. Preferably, the at least one locking element is integral with the wind deflector element.
[0010] Furthermore, it is proposed that at least one of the bracket elements has at least one bracket which, in an assembled state, is designed to engage with the locking element. This allows for a particularly simple locking movement.
[0011] Furthermore, it is proposed that the locking element be lockable along the longitudinal direction of the wiper blade. This allows for a particularly simple assembly process.
[0012] Furthermore, it is proposed that the locking element have a barbed shape. This allows for a locking element with a simple, easily manufactured form. In this context, a "barbed shape" is defined as a shape with an inclined surface rising in the opposite direction to the final assembly direction and with an edge adjacent to the inclined surface, whereby, after movement in the final assembly direction, the edge prevents further movement of the element resting against the locking element.
[0013] Furthermore, it is proposed that the at least one retaining element and the at least one locking element be manufactured in one piece. This allows for a simple-to-manufacture retaining unit. In this context, "in one piece" is understood to mean, in particular, at least a materially bonded connection, for example, by a welding process, an adhesive bonding process, an injection molding process, and / or another process that would appear appropriate to a person skilled in the art. Advantageously, "in one piece" is also understood to mean "one-part." "One-part" is understood to mean, in particular, formed in a single piece. Preferably, this single piece is manufactured from a single blank, a compound, and / or a casting, most preferably by an injection molding process, especially a single- and / or multi-component injection molding process.
[0014] Furthermore, the invention relates to a wind deflector element of a wiper blade device according to the invention.
[0015] Furthermore, the invention relates to a method for assembling a wiper blade device with at least one bracket element and with at least one wind deflector element, and with at least one holding unit for positively connecting the at least one bracket element with the at least one wind deflector element, which includes at least one holding element that is guided along a longitudinal direction of the wiper blade into a final assembly position.
[0016] It is proposed that the at least one holding unit includes at least one locking element that locks the at least one bracket element to the at least one wind deflector element along the longitudinal direction of the wiper blade. This allows for easy assembly during the process.
[0017] The wiper blade device according to the invention is not intended to be limited to the application and embodiment described above. In particular, the wiper blade device according to the invention may, in order to fulfill a function described herein, have a different number of individual elements, components and units than the number mentioned herein. drawing
