Description

Wind guide assembly for the longitudinal sides of a vehicle roof and roof assembly for a roof opening of a vehicle roof

Technical Field

The present application relates to a wind deflector assembly for a longitudinal side of a vehicle roof and a vehicle roof assembly for a vehicle roof opening of a vehicle roof, having such a wind deflector assembly.

Background

The motor vehicle may have a roof opening which can be closed and at least partially released by means of a movable roof element. The air guide assembly serves to prevent air turbulence or other disruptive air flows from penetrating into the vehicle interior in the event of at least partial release of the roof opening. JP2006-315615a discloses an air guide device for the longitudinal side of a vehicle roof, which has a rigid air guide element.

Disclosure of Invention

It would be desirable to provide a wind guide assembly and a roof assembly that reliably reduces wind noise.

According to at least one embodiment, a wind deflector assembly for a roof longitudinal side is provided. The roof has a front side and two longitudinal sides oriented transversely to the front side. The front side faces, for example, the windshield. These two longitudinal sides extend in particular between the windshield and the rear window, i.e. in particular in the main extension direction of the vehicle. The air guide assembly is provided with a flexible air guide element. The wind-guiding element is, for example, a net, a fabric, a film or another flexible element that can be folded and unfolded, in particular. The air guide assembly is provided with a fixed rail used for fixing the air guide assembly on the vehicle roof. The air guide assembly is provided with a tensioning rail. The tensioning rail is movably arranged relative to the fixed rail. The air guide assembly is provided with a spring. The tension rail is pressed by the spring in a direction away from the fixed rail. The air guide element is fixed on the fixed rail on one side. The air guiding element is fixed on the opposite side to the tensioning rail.

Wind noises caused by lateral flows of the oncoming wind can be avoided in the assembled state at the roof of the motor vehicle by means of the wind guide assembly having the flexible wind guide element. In particular, these noises are caused by the interruption of the flow at the edge of the mechanical structure, i.e. for example at the edge of the mechanical structure provided for moving the movable roof element relative to the roof. The lateral wind guide assembly, which can be mounted on the longitudinal side of the vehicle roof, reduces or prevents noise generated by lateral wind in the ready state.

Since the air guiding element is of flexible design, rattling is prevented in rigid air guiding elements, for example in injection molded parts. Furthermore, in the case of injection-molded parts, the height of the shield is limited by the installation space. The net as a wind guiding element can cover a larger area than a rigid wind guiding element. The air guide assembly can be completely assembled especially before being assembled on the vehicle roof and is therefore easy to use. According to other embodiments, it is possible to mount the spring on the vehicle roof only during the assembly of the air guide assembly. The additional sealing strip on the cover can be omitted. Furthermore, a smaller tolerance chain is achieved. Furthermore, the wind guide assembly is characterized by a low complexity. The spring always holds the air guiding assembly, in particular the air guiding element, under tension, whereby rattling can be largely avoided and, according to an embodiment, the air guiding assembly is even configured to be rattle-free. For example, the spring is substantially triangular or quadrangular in configuration. Thus, for example, a triangle or a quadrilateral of forces is realized, which results in a resultant force in the z direction.

According to at least one embodiment, the spring is a separate member arranged between the tensioning rail and the fixed rail. The spring is first of all designed separately from the tensioning rail and separately from the fixed rail and is coupled to at least one of the rails. The spring is for example a spring wire with a concave basic shape.

According to at least one embodiment, the fixed rail has a sliding groove. The spring is fixed with one end on the fixed rail, and the other end of the spring is movably held in the slide groove. A translatory clearance for the spring is thus formed, which simplifies the relative movement of the tensioning rail and the fixed rail with respect to each other.

According to at least one embodiment, the spring is in contact in the region of the fixed rail and/or the tensioning rail to which the air guiding element is fixed. The spring is therefore covered by the air guiding element.

According to at least one embodiment, the spring is configured as part of the tensioning rail. The tensioning rail is therefore at least partially configured to be elastic and sprung, so that the tensioning rail is pressed away from the fixed rail.

According to at least one embodiment, the fastening rail has a mounting interface for fastening to a vehicle roof. The mounting interface is formed, for example, by one or more hooks, by means of which the fastening rail can be connected, for example, to a guide rail or a roof frame.

According to at least one embodiment, the tensioning rail and the fixed rail are connected to each other by means of a hinge. A simple and reliable coupling of the tensioning rail and the fixed rail is thus achieved.

According to at least one embodiment, the tensioning rail is movable along the fixed rail. For example, the fixed rail has a further sliding groove, in which the tensioning rail is guided. The additional sliding groove enables the tensioning rail to be moved not only transversely to the main direction of extension of the fixed rail for tensioning the air guiding element, but also along the fixed rail in order to fill the desired area with the air guiding element, in particular when the cover is open.

According to at least one embodiment, the tensioning rail, the fastening rail and the air guiding element extend completely along one plane. In particular, the tensioning rail and the fastening rail are U-shaped, in contrast to conventional air guiding assemblies for the front side of a roof opening. The tensioning rail and the fixed rail each extend substantially linearly in this plane. In the tensioned state, the net extends linearly in a planar manner in said plane.

According to at least one embodiment, a roof assembly for a roof opening of a vehicle roof has a wind guide assembly according to at least one embodiment. The roof assembly has a side frame member that can be coupled to a longitudinal side of a vehicle roof. The roof assembly has a movable roof element which is coupled to the frame element and can be moved along the frame element. The air guide assembly is arranged between the roof element and the frame element. The fixed rail is fixed to the frame member. The tensioning rail is in contact with the roof element when the roof element is moved relative to the frame element. The wind guide element extends in particular from the roof element to the frame element when the roof element projects with its rear edge beyond the roof. Thus, when the roof element has not yet been completely displaced rearward, but rather only projects with its rear edge, i.e. in the so-called tilted position, the wind guiding element is already at least partially in its extended tensioned state. Conventional wind guides for the front side are still retracted in this position and wind noise cannot be avoided. The wind guide element according to the present application already reduces wind noise, in particular wind noise generated by lateral streaming of the oncoming wind, even in the so-called tilt position of the roof element. Furthermore, the wind guiding element covers the mechanical structure and thus improves the aesthetic appearance of the roof assembly.

Further advantages, features and extension solutions result from the examples set forth below in connection with the drawings.

Detailed Description

Fig. 1 shows a schematic view of a roof 102 of a motor vehicle 127. The roof 102 extends substantially along a plane extending from the xy-direction. In particular, the roof extends between a windshield 126 and a vehicle rear window 128. The x direction corresponds here to the main direction of extension of the motor vehicle 127 and of the roof 102, which therefore extends between the windshield 126 and the rear window 128.

The roof 102 has a roof opening 121. The roof opening 121 can be closed by a roof element 123 and can be at least partially released. For this purpose, the roof element 123 is movable in the x-direction relative to the rest of the roof 102. The roof opening has a front side 103. The front side 103 faces the windshield 126 and extends substantially in the y-direction. The roof opening 121 has two longitudinal sides 101. The longitudinal sides 101 of the roof opening 121 extend substantially in the y-direction. The longitudinal sides 101 delimit the roof opening 121 in the y-direction.

The motor vehicle 127 has, for example, a front wind guide 129 associated with the front side 103. According to other embodiments, the front wind guiding device 129 is omitted. The front wind deflector 129 is arranged in particular pivotably relative to the vehicle roof 102 and pivots in the z direction when the roof element 123 is moved rearward in the x direction relative to the rest of the vehicle roof 102. The z direction corresponds in particular to the vertical direction, while the x direction and the y direction extend horizontally in the normal operating position of the motor vehicle 127. The x-direction, the y-direction and the z-direction each extend in particular perpendicularly with respect to one another.

The roof element 123 is coupled with the frame element 122 by means of a mechanical mechanism 131 (fig. 4). The frame element 122 is fastened to the vehicle roof 102, in particular along the longitudinal side 101, and serves to hold the vehicle roof element 123 and to guide the movement of the vehicle roof element 123 relative to the rest of the vehicle roof 102. In particular, the frame element 122 has guide rails. In particular, on the rear end of the frame element 122 or of the roof opening 121 facing the rear window 128, on both sides of the roof opening 121, there is arranged a wind guiding assembly 100.

Fig. 2 illustrates a wind guide assembly 100 according to an embodiment. The wind guide assembly 100 has a flexible wind guide element 104. The flexible wind-guiding element 104 is, for example, a net, a woven or knitted fabric or another flexible element, such as a film or rubber. According to other embodiments, ribs 136 may additionally be upstanding from fixed rail 105 (fig. 5). The ribs are particularly useful if the wind guiding element 104 is not to be tensioned, for example by lowering the lift and/or at high speeds.

The wind deflector assembly 104 is designed in particular to reduce the spread of the oncoming wind in the direction of the interior of the motor vehicle 127 when the roof opening 121 is at least partially open and the roof element 123 is at least partially extended during operation of the motor vehicle.

The air guide assembly 100 has a fixed rail 105. The fixing rail 105 is used to fix the air guide assembly 100 to the frame member 122. The air guide assembly 104 is fixed to the fixed rail 105 at one end 111. The fixed rail 105 has a main extension direction along the x-direction. The fixed rail 105 extends more in the x-direction than in the y-direction and in the z-direction.

The air guide assembly 100 has a tension rail 106. The tensioning rail 106 is used to hold the second end 112 of the net 104. The net 104 is fixed to the tensioning rail 106 at an end 112 opposite the end 111 in the z-direction. The tensioning rail 106 is in particular movable relative to the fixed rail 105 along the z-direction. In particular, tensioning rail 106 and fixed rail 105 are connected to each other by means of a hinge 116. The tensioning rail 106 can thus pivot relative to the fixed rail 105 about a rotational axis predetermined by the hinge 116.

The air guide assembly 100 has a spring 107. In the illustrated embodiment, the spring 107 is a separately configured member with respect to the fixed rail 105 and the tension rail 106. According to other embodiments, which are not explicitly shown, the spring is, for example, an integral component of the tensioning rail 106 and/or the fixing rail 105. According to an embodiment, the spring 107 is inserted and/or injection molded into the stationary rail 105. When the roof element 123 is closed, the spring 107 can perform a compensating movement relative to the tensioning rail 106. Alternatively or additionally, the spring 107 may also be suspended in the tensioning rail 106. Thus, the spring 107 has a positive positioning on the tensioning rail 106. According to an embodiment, this causes the pin 118 to move in the coupling chute 117 (fig. 3).

The spring 107 exerts a spring force on the fixed rail 105 and the tension rail 106 in the z-direction. Thus, the spring 107 presses the tension rail 106 away from the fixed rail 105. The movement of the tensioning rail 106 in the z direction away from the fixed rail 105 is limited by the wind guiding element 104. Therefore, the spring 107 tensions the air guiding element 104 when the air guiding assembly 100 is in the extended state. In particular, the tensioning rail 106 is in contact with the roof element 123, as is schematically illustrated in fig. 4.

In the lowered position of the roof element 123, in which the roof element 123 completely closes the roof opening 121, the roof element 123 presses the tensioning rail 106 in the direction of the fixed rail 105. The tension rail 106 and the fixed rail 105 are arranged relatively close to each other at a small distance. The wind guiding element 104 is at least partially folded and in particular not unfolded. When the rear edge 124 of the roof element 123 is raised in the z-direction relative to the rest of the roof 102, while the front edge 125 (fig. 1) of the roof element 123 has not yet moved substantially in the z-direction, i.e. the roof element 123 is in its so-called tilted position, the spring 104 presses the tensioning element 106 further onto the underside of the roof element 123.

The tensioning rail 106 thus moves together with the roof element 123 in the z direction. The wind guiding element 104 is thus tensioned. Thereby, the wind guiding element 104 prevents wind from flowing into the roof opening 121 from the side. Furthermore, the wind guiding element 104 at least partially blocks direct view of the mechanical element 131 and/or the frame element 122.

When the roof opening 121 is opened further and for this purpose the roof element 123 is moved in the x direction relative to the rest of the vehicle roof 102, the roof element 123 also moves relative to the wind guide assembly 100. The tensioning rail 106 is here always in contact with the roof element 123. The tensioning rail 106 and the roof element 123 are pressed against each other by the spring 107. The space between the frame element 122 with the fastening rail 105 and the roof element 123 with the tensioning rail 106 is therefore covered by the air guiding element 104. The wind guide element 104 extends from the frame element 122 in the z direction to the roof element 123, independently of the position of the roof element 123.

In the embodiment of fig. 2, the spring has a first end 108 and a second end 109. The first end 108 is coupled to the fixed rail 105 so as not to be movable relative to the fixed rail 105. The second end 109 is guided in a slide groove 110 of the fixed rail 105. The runner has a course in the x-direction. Thus, the second end 109 of the spring 107 is movable in the x-direction relative to the fixed rail 105. Thus, a translation of the spring can be achieved. Thereby simplifying pivoting of the tensioning rail 106 relative to the fixed rail 105.

The fixed rail 105 has a mounting interface 115. For example, the mounting interface 115 has a hook or hooks, threaded connections, adhesive portions, welds, or other connections that connect or are capable of connecting the stationary rail 105 with the frame member 122. The fixed rail 105 can therefore be connected to the roof element 123 in a manner fixed relative to the roof element 123.

The spring is in contact with the tensioning rail 106 in the region 113, in which the wind guiding element 104 is fixed to the tensioning rail 106. Analogously, the spring 107 is coupled to the fixed rail 105 in the region 114 of the fixed rail 105, in which the air guiding element 104 is fixed to the fixed rail 105. In particular, both the spring 107, the air guiding element 104, the fixed rail 105 and the tensioning rail 106 extend in their respective main extension direction along a plane which is open out in the x-direction and the z-direction.

Fig. 3 shows a schematic view of a wind guiding assembly 100 according to another embodiment. The embodiment of fig. 3 corresponds substantially to the embodiment of fig. 2. Their differences are discussed in particular below.

The fixed rail 105 of the air guide assembly 100 according to the embodiment of fig. 3 has a coupling sliding groove 117 in addition to the first sliding groove 110. The coupling runner 117 serves to couple the fixed rail 105 with the tension rail 106. For this purpose, the tensioning rail 106 has a pin 118, which is guided in the coupling slot 117. The coupling link 117 has a profile 119 extending obliquely to the x-direction and the z-direction. Thus, as the tension rail 106 moves in the z-direction relative to the fixed rail 105, the tension rail 106 also moves in the x-direction. Thus, when the roof element 122 is pivoted in the z direction, the tensioning rail 106 moves both in the z direction and rearward in the x direction. This allows the position of the wind guide element 104 to be adapted to a desired position. In particular, the air guiding element extends in the extended state at a rearward inclination in the x direction.

To produce the wind guide assemblies of the different exemplary embodiments, the cut wind guide element 104 is first inserted into a tool and held, for example, by means of a needle. The air guiding element 104 is then encapsulated by injection molding, so that a fixed rail 105 and a tensioning rail 106 are formed. Other constructions are also possible, for example, connecting the air guiding element to the already produced fastening rail 105 and tensioning rail 106, for example by means of a rolled edge. Alternatively or additionally, the fastening can also be effected by means of sewing.

Fig. 4 shows a schematic illustration of a roof assembly 120 with a wind guiding assembly 100 according to the embodiment of fig. 2. The spring 107 tensions the wind guiding element 104 between the frame element 122 and the roof element 123. The fixed rail 105 is fixed to the frame member 122 by means of the mounting interface 115.

Accordingly, the wind guide assembly 100 according to other embodiments, for example according to the embodiment of fig. 3, is also tensioned between the roof element 123 and the frame element 122 in the roof assembly 120 according to other embodiments. In particular, the tensioning rail 106 extends along a lateral edge 130 of the roof element 123 extending in the x direction between the front edge 125 and the rear edge 124. The fixed rail 105 extends along the x direction along an elongated frame element 122 extending in the x direction, for example along a guide rail.

Fig. 5 and 6 each show a schematic view of a wind guide assembly 100 according to another embodiment. The exemplary embodiment of fig. 5 and 6 corresponds substantially to the exemplary embodiment of fig. 3. Their differences are discussed in particular below.

The spring 107 has two spring elements 137 which are independent of one another. More or fewer separate spring elements may be provided. These spring elements each exert a force in the z direction on the tensioning rail 106. The spring elements 137 are each rigidly coupled to the fixed rail 105 by means of a connection 132 (fig. 6). The spring elements 137 are each fixed to the fixed rail 105 at the connection 132 so as to be immovable relative to the fixed rail 105.

The spring elements 137 each have a free end 134 facing the tensioning rail 106. The spring elements 137 each have a contact surface 133 at the free ends 134 with the tensioning rail 106. The free end 134 and the tensioning rail 106 are coupled movably relative to each other. Thus, the contact surface 133 moves along the tension rail 106 as the tension rail 106 moves between its stowed position and its extended position.

In the fixed rail 105, a groove 135 is provided for each sub-spring 137. The sub-spring 137 is at least partially arranged in this groove 135 when the tensioning rail 106 is in its retracted position.

A rib 136 protruding in the z direction is arranged on the fixed rail 105. The ribs 136 serve, for example, to additionally stabilize the wind guiding element 104. According to other embodiments, the ribs 136 are omitted.

The air guide assembly 100 for the longitudinal sides 101 of the roof opening 121 enables a simple construction and reliable reduction of wind noise caused by lateral wind flows in the oncoming wind. No additional sealing strips need to be glued or inserted on the roof element 123. The spring 107 reliably tensions the air guiding element 104. Since the air guiding element 104 is flexible and is also pressed against the top plate element 123, for example, by the spring 107, a preload force is always present. The mesh may also act as a restriction to restrict movement of the tensioning rail 106 away from the fixed rail 105. Thus, for example, a small gap between the tensioning rail 106 and the roof element 123 is possible. This can prevent possible squeaking noises, for example. In particular, manufacturing-related differences and/or inaccuracies of the individual components of the air guiding assembly 100 can be compensated for by the combined action of the spring 107 and the flexible air guiding element 104. A low tolerance chain can be achieved. Whereby rattling noise can be avoided. The air guiding assembly 100 for the lengthwise sides 101 can be preassembled as a coherent structural unit. According to other embodiments, the spring 107 is mounted on the roof assembly 102 only during mounting, thus achieving a smaller space requirement for storage. Overall, a cost-effective roof assembly 120 can be achieved, since, for example, sealing strips on the roof element 123, which would have to be provided in the case of a rigid wind-guiding element, are eliminated. The air deflection assembly 100 has a small tolerance chain and low complexity.
