Description

The invention relates to an interior trim part for a means of transport, wherein the interior trim part has an axle receptacle and a hinge axis.

From the prior art various axle mounts for receiving a hinge axis for storage flaps are known, for example, describes the US 4,967,924 A a capping device for a container having a releasable hinge axis. From the US Pat. No. 6,896,196 B2 Also, a hinged lid for a container for a motor vehicle is known, which can be completely detached. The EP 0 766 360 A1 discloses a housing with a hinged lid, a housing pot and a fastener connecting the lid to the housing pot.

FR 2 641 506 A1 discloses a device by means of which a luggage compartment cover can be fastened to a lateral trunk lining, DE 15 59 846 B relates to a hinge for pivotally connecting a hinge pin to a terminal plate. The hinge consists of an approximately U-shaped holding part. In contrast, the invention has for its object to provide an improved interior trim part for a transport with an axle and a hinge axis.

The object underlying the invention is achieved with the features of the independent claim. Preferred embodiments of the invention are indicated in the dependent claims.

According to the invention, an interior trim part is provided for a means of transport, wherein the interior trim part has an axle receptacle and a hinge axis, wherein the axle receptacle can be latched to the interior trim part, an axle bearing being formed on the axle receptacle. The axle bearing is designed to receive the hinge axis, wherein the hinge axis is designed to guide a pivoting movement of a cover arranged on the hinge axis between an open position and a closed position of the cover for releasing and covering a recess of the interior trim part. The axle receptacle can be inserted into a receptacle of the interior trim part. This receptacle of the interior trim part forms a receptacle perpendicular to the hinge axis direction and enclosing in the hinge axis direction pocket, wherein the axle receptacle is inserted into the pocket of the interior trim part. The use of such a receptacle, for example in the form of a pocket, which is formed on the interior trim part, has the advantage that on the one hand a simple yet mechanically stable connection of the axle to the interior trim part is possible acting on the hinge axis forces are optimally on the Axle and thus transferred to the interior trim part. The use of further fixing points to prevent movement of the axle perpendicular to the extension surface of the interior trim part, is thus superfluous, which offers a material savings as well as a faster mounting option.

Furthermore, reinforcing ribs are formed on the inner lining part in the region of the receptacle of the inner lining part at the level of the receptacle of the inner lining part, the reinforcing ribs being parallel to the hinge axis, the reinforcing ribs being parallel to the hinge axis, the hinge axis running on the rear side of the inner lining part and the lid on the front side of the interior trim part can perform the pivotal movement. The use of such reinforcing ribs in the region of the receptacle of the interior trim part has the advantage that the fracture strength in the region of the receptacle of the interior trim part is further increased. A movement of the hinge axis in the axle bearing thus does not lead to a deformation of the interior trim part under normal conditions. In addition, through the use of reinforcing ribs, an optimum force transmission of the forces acting on the receptacle of the interior trim part to the interior trim part itself takes place, without a high cost of materials and concomitantly high costs associated therewith.

In the following, means of transport mean any type of means of transport, such as aircraft, motor vehicles or rail vehicles, which have interior trim parts. In addition to trim parts for a passenger compartment, these may also be trim parts of a luggage storage space or a motor drive space.

The interior trim part according to the invention has the advantage that this can be produced in a cost effective manner. Thus, for example, in a basic variant, the interior trim part without the axle receptacle and the hinge axis can be used in the means of transport, in order thus to release the recess in a permanent manner. For example, the recess of the interior trim part is a removal opening for a storage space of the means of transport.

In a higher-quality version, the axle receptacle can now additionally be locked in a simple manner with the interior trim part, and then the hinge axis in the axle bearing of the Axle be used to create a higher-quality interior trim part by two simple and quick steps. Nevertheless, the same interior trim part can be used in the basic variant as well as in the higher-valued variant, so that production costs for such an interior trim part are incurred only once.

In addition, such a Innenverkleidungstell with axle and hinge axis, wherein the Achsaufnahme is latched to the interior trim part, the advantage of a cost-effective production, since a complex spraying of the axle, for example, in an injection molding process, attributable to the interior trim part. This reduces the complexity of the large tool used to make the inner gate part.

According to a further embodiment of the invention, the axle bearing is designed for snapping the hinge axis. This allows easy mounting of the hinge axis on the axle box. However, the axle bearing is preferably designed to release the hinge axis from a predetermined force on the hinge axis, which ensures that the axle is released from the axle bearing if the force is too high. This could prove to be particularly advantageous, for example in motor vehicles at places on the instrument panel, since in a crash case may be required that trim parts can be released in a defined manner from the inner lining by the crash, so as to reduce the risk of injury of motor vehicle occupants.

According to a further embodiment of the invention, the axle mountings and the interior trim part consist of different materials. For example, a particularly high-quality, low-friction and / or highly stable material can be used for the axle mount, whereas the material of the interior trim part can be adapted to an optimum feel of an occupant of the transport vehicle ,

According to a further embodiment of the invention, the axle bearing on a sliding coating, which ensures the advantage of a particularly good smooth turning ability of the hinge axis in the axle box.

According to a further embodiment of the invention, the axle bearing is formed by at least one circular arc, wherein the circular arc is formed on a wall of the axle, wherein the circular arc is formed for receiving the hinge axis, the use of such a circular arc in turn has the advantage that the axle box acting forces can be transmitted in an optimal manner to the axle and thus on the interior trim part. In addition, a counter-bearing of the cylindrical hinge axis is formed by the circular arc shape of the journal bearing, so that the hinge axis is thus stored in an optimal manner in the axle box.

According to a further embodiment of the invention, a guide surface is integrally formed on the circular arc on the side facing away from the wall of the circular arc, wherein the guide surface forms a funnel cross section with the wall. The use of such a guide surface, which forms a funnel cross-section with the wall, has the advantage that it allows a self-locating threading and mounting of the hinge axis on the axle bearing. The pressing of the hinge axis on the circular arc-shaped axle bearing thus leads to a self-locating positioning of the hinge axis on the axle and a subsequent snapping the hinge axis in the opening, which is formed by the circular arc of the journal bearing.

According to a further embodiment of the invention, a first latching element is formed on the wall on the side facing the circular arc, wherein the first latching element and the circular arc form a snap-receiving for the hinge axis. Again, the above is true that thus easily mounting the hinge axis through the axle is possible. In addition, a mechanically simple mechanical determination of the overall system is possible by using a combination of circular arc and first locking element, so that in a complex manner that force can be defined, from which the axle bearing releases the hinge axis for "snapping".

According to a further embodiment of the invention, the first latching element is a latching projection. In this case, for example, the latching projection may have a holding surface protruding obliquely from the wall, wherein the holding surface and the guide surface are aligned parallel to one another.

According to a further embodiment of the invention, the axle receptacle can be latched to the interior trim part by at least one second latching element, wherein the second latching element is formed on the interior trim part. Preferably, the second latching element is laterally offset for receiving offset formed on the interior trim part. Thus, centrally acting on the axle receiving forces are absorbed by the inclusion of the interior trim part, whereas forces which lead to a tilting of the axle in the recording of the Interior trim parts lead, can be additionally absorbed by the second locking elements.

According to a further embodiment of the invention, the axle receptacle is latched to the inner lining part by at least a third latching element, wherein the third latching element is formed on the axle and is formed for latching in the receptacle of the interior trim part. Thus, a further breakpoint is created, by means of which the axle receiving is fixed to the interior trim part. Preferably, the second and third locking element are designed so that the locking of the axle and the interior trim part is substantially irreversible. In other words, a unlatching of axle and interior trim part is no longer readily possible. A removal of axle from the interior trim part will thus usually end up with a partial damage to the axle.

According to a further embodiment of the invention, the first and / or second latching element is a barb-shaped latching lug in order to thus realize this irreversible latching.

According to a further embodiment of the invention, the recess of the interior trim part is a removal opening for a storage space of the transport means. If the means of transport is, for example, a motor vehicle, this storage space may be a storage space in the instrument panel of the motor vehicle or the door trim of the motor vehicle, such as a map pocket of the door trim.

In the following, preferred embodiments of the invention are explained in more detail with reference to the following drawings.

Show it:

1 a schematic view of process steps for mounting an axle and a hinge axis on an interior trim part,

2 a schematic view of an interior trim part with an axle and a hinge axis,

3 a schematic view of a storage device for a means of transport.

Hereinafter, similar elements will be denoted by the same reference numerals.

The 1 shows a schematic view of steps for mounting an interior trim part 100 , Starting from the interior trim part 100 comes with the interior trim part 100 an axle mount 102 locked. The axle mount 102 has an axle box 120 on, which for receiving a hinge axis 126 is trained. The hinge axis 126 is to guide a pivoting movement of a arranged on the hinge axis dachshund 106 between an open position and a closed position of the lid 106 for releasing and covering a not visible here recess of the interior trim part 100 educated.

The assembly of the axle mount 102 on the interior trim part 100 done in the 1 by a movement in the direction 124 , ie by inserting the axle 102 in a bag 108 , which on the interior trim part 100 is formed by the insertion of the axle 102 in the pocket 108 snap locking elements 116 in accordance with opposing openings 114 the pocket 108 one. This creates an irreversible locking connection between the axle 102 and interior trim part 100 ,

Additionally are on the interior trim part 100 further locking elements 112 provided, which also to an irreversible locking between the interior trim part 100 and axle 102 to lead. For this purpose, both the locking elements 116 as well as the locking elements 112 barb-shaped designed as locking lugs.

Further in the 1 the axle bearing is visible 120 , which for snapping the hinge axis 126 is trained. The axlebox 120 is formed by a circular arc, with the circular arc on a wall 118 the axle mount 102 is formed. The circular arc points to the wall 118 opposite side a guide surface 122 which is arranged obliquely and which are parallel to the hinge axis 126 extends. This guide surface 122 forms with the wall 118 a funnel cross section, so by inserting the hinge axis 126 in the axlebox 120 by a movement in the direction 132 a self-locating snap the hinge axis 126 in the axlebox 120 takes place.

In addition are on the wall 118 the axle mount 102 further locking elements 130 formed, wherein the locking elements 130 together with the circular arc of the axle of the axlebox 120 form a snap-in receptacle for the hinge axis. The holding effect of the hinge axis 126 in the Achslager 120 is reinforced by the fact that the locking elements 130 each having obliquely projecting from the wall retaining surfaces, said retaining surfaces 134 and the guide surface 122 are aligned substantially parallel to each other. However, this is not absolutely necessary, as here also a V-shaped arrangement of support surface 134 and guiding surface 122 is possible, the decisive factor here is that the holding surface 134 and the guide surface 122 so are arranged to each other and also the elasticity of the axle bearings 120 used material is dimensioned so that at an increased force on the hinge axis 126 a detachment of the hinge axis 126 from the axlebox 120 is possible. This could be provided, for example, in the event of a crash, in which from a predefined force a release of hinge axis 126 and axle bearings 120 is possible. It is also possible to define that force so that, for example, a tilted incorrect operation, ie a tilted opening and closing movement of the lid 106 a release of hinge axis 126 from the axlebox 120 he follows.

As further from the 1 can be seen, the locking elements 112 laterally to the bag 108 offset so that canting forces, which on the axle bearings 120 act effectively from these locking elements 112 be recorded.

For optimum sliding support of the hinge axis 126 in the axlebox 120 To allow the circular arc of the axle box on its inside 136 be provided with a corresponding lubricious coating. For example, here is a corresponding Teflon coating for a friction-reduced storage of the hinge axis 126 be used.

Further in the 1 visible are reinforcing ribs 110 which is in the area of the bag 108 of the interior trim part 100 are formed. These reinforcing ribs 110 run parallel to the hinge axis 126 ,

At the hinge axis 126 are webs 128 molded, with the lid 106 with these bars 128 connected is. This compound can either one piece z. B. be given by means of a previously performed welding process or the lid 106 can go to the footbridges 128 be connected with screw, rivet or locking connections.

The axlebox 120 thus forms with the circular arc a "mouth", said mouth for receiving the hinge axis 126 is provided.

It should be noted that instead of using an axle box 120 , which for snapping the hinge axis 126 is provided, an axle bearing can be used, through which an axle is pushed through. In this case, a corresponding journal bearing would have annular openings through which the hinge axis 126 is pushed through.

The 2 shows a schematic view of a fully assembled interior trim part with axle and hinge axis. The hinge axis 126 which in the 2 however, is not apparent, is in the axle box 120 used to allow a pivotal movement of the lid 106 in one direction 200 from the interior trim part 100 to allow away.

How clear in the 2 can be seen, is the axle 102 over the barb-shaped locking lugs 112 in your pocket 108 pushed, causing the locking lugs 112 an irreversible locking of axle 102 and interior trim part 100 cause. However, the situation is different with the locking of axle bearings 120 and hinge axis 126 , The axle bearing is designed so that the hinge axle can snap into the axle box. However, in order to prevent breakage of the axle bearing with tilting of the hinge axis relative to the bearing, the latching force of the hinge axis in the axle bearing is designed so that in severe abuse, the hinge axis can disengage from the axle bearing. Preferably, the design of the journal bearing is further designed so that a user independently the hinge axis 126 back in the axlebox 120 can use.

The 3 shows a schematic cross-sectional view of, for example, a bag 304 , which in a door trim of a motor vehicle door 310 given is. The pocket 304 has a U-shaped cross-section, which at its open ends of an interior trim part 100 is limited, in the "base variant" is for a corresponding motor vehicle door 310 only the use of interior trim parts 100 provided, which partially a storage space 302 cover, which through the bag 304 is formed. A lid 108 is not provided in the basic version. In other words, so is the removal opening for the storage space 102 only partially through the interior trim parts 100 Covered, a user can free in the storage space 302 reach in there as a lid 106 in this case is not provided.

In a higher value variant, there is now the possibility of the storage space 102 with the lid 106 to close. For this purpose is on the lid 106 a hinge axis 126 arranged, this hinge axis 126 in a corresponding axle box 120 an axle mount 102 In addition, this axle is 102 with the interior trim part 100 rusted, in which case the axle 102 in a corresponding receptacle, for example in the form of a bag 108 , the interior trim part 100 is inserted and with the interior trim part 100 rusted.

By using the hinge axis 126 in the axlebox 120 is a pivoting movement of the lid 106 in one direction 200 possible, thus providing a removal opening for the storage space 302 To release, To cover the lid when closed 106 To hold in its closed position, various possibilities may be provided in the 3 is for example a locking element 300 shown, which is arranged on the interior trim part. In this locking element 300 is a counter-locking element 308 engaged, wherein the locking connection between the unlocking elements 300 and 308 is reversible. That is, by a force in the direction 200 a user is capable of doing the locking elements 300 and 308 to solve each other, thus a pivotal movement of the lid 106 in the direction 200 to move.

Alternatively or additionally, it is possible, the hinge axis 126 be provided with corresponding spring elements, said spring elements can be designed depending on the purpose so that the lid 106 in its closed position without external force and without the use of locking elements 300 and 308 independently in its closed position, as in the 3 shown, can be held.

Further in the 3 the guide surface is visible 122 , which at the circular arc of the axle bearing 120 is formed. By a simple movement in the direction 312 can thus the hinge axis 125 self-locating in the axle box 120 be used, with a snap-locking connection between axle bearings 120 , Locking elements 130 and hinge axis 126 takes place.
