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

It demonstrate:

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.

in the Below, similar elements become the same with each other Reference number marked.

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 for guiding a pivoting movement of a lid arranged on the hinge axis 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 inserting the axle mount 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 axlebox 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 are arranged to each other and also the elasticity of the axle bearing 120 used material is dimensioned so that at an increased force on the hinge axis se 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 Innenverklätzsteils 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 bearings. Preferably, the design of the journal bearing is further designed so that a user independently the hinge axis 126 back to 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 "basic 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 106 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 is used. In addition, this axle is 102 with the interior trim part 100 latched, 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 is locked.

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 release. When closed, the lid 106 can keep in its closed position various options can 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 126 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.
