AREA

The present application relates to a vehicle stair system. More specifically, the present application relates to a vehicle stair system with at least one folding step for the vehicle interior.

BACKGROUND

In the field of vehicle construction, the space available is limited, particularly in the interior of residential structures. However, it is often of ı5 advantage to divide the living space on different levels. In order to get from a lower level to a higher level, climbing aids such as stairs or steps are necessary. These can be independent elements or separate climbing aids, or integrated in the rest of the interior.

OVERVIEW

In both cases, that the climbing aids are separate or integrated into the interior, space is required for the climbing aids and / or they must be precisely positioned (e.g. hooked in and / or locked) in order to be used safely. Furthermore, known climbing aids therefore have to be stored in a complex manner and are therefore uncomfortable for the user to use or require space in the accessible part of the interior which could be used for other purposes.

It is therefore the object of the present disclosure to propose a vehicle stair system as a climbing aid, which is simple and safe to use and space-saving. il

DETAILED DESCRIPTION OF THE EMBODIMENTS

With initial reference to Figure 1, a vehicle stair system 10 is disclosed. The vehicle staircase system 10 comprises a storage space 20 and a mobile unit 30. A linear guide 70 movably connects the mobile unit 30 to the storage space 20, so that the mobile unit 30 can be pushed into the storage space 20. In this embodiment,

SB -7- LU101097 remove the mobile unit 30 with the storage space when the mobile unit 30 is inserted into the storage space 20 (not shown). Furthermore, the mobile unit 30 latches when it is pushed into the storage space 20. The arrow X indicates the direction of movement of the mobile unit 30 in relation to the storage space 20. The distance shown between the storage space 20 and the mobile unit 30 is exemplary and can be chosen as desired, since only the folding step 40 has to be free of the storage space 20 in order to be unfolded, so that the vehicle stair system can be used. | In Figure 1, the mobile unit 30 is pulled out of the storage space 20 and shown in the further end position, in which the mobile unit 30 can be used and also locked. As can be seen in FIGS. 1 and 2, a depression of the mobile unit 30 is achieved in this embodiment by a peripheral frame 80 which is applied to a wall 50 of the mobile unit 30. The depth of frame 80 and wall 50 are selected so that the mobile unit 30 fits into the storage space 20. A folding step 40 is arranged in this depression.

In Figure 1, the folding stage is shown in a folded state, wherein mainly a vertical element 44 can be seen, which almost completely hides a step element 42 arranged behind it in the view of Figure 1. The vertical element 44 of the folding step 40 is connected to the step element via a second pivot axis B (at the top of the folding step 40 in FIG. 1).

In the illustration of FIG. 1, the second pivot axis B is arranged at the top of the folding step 40 between the clearly visible vertical element 44 and the step element 42 lying in depth behind it. The step element 42 is connected to the wall 50 via a first pivot axis A. (at the bottom of the folding stage 40 in Figure 1). The first pivot axis A is arranged between the wall 50 and the tread element 42. The recess can also be worked out from a wall of the mobile unit, or a combination of the two solutions mentioned above can be used. Le

The depression of the mobile unit 30 is divided by a second step element 45. In this embodiment, the second tread element 45 is part of the frame 80 and is flush with it. In the area of the second tread element 45, the wall 50 has an opening or a recess 64. Thus, a user can put his foot through the wall 50 of the mobile unit 64 and achieve a safe stand.

In Figure 2, the mobile unit 30 of Figure 1 is shown with the folding stage 40 unfolded. The two elements of the folding stage were each folded away from the wall 50 about the first and second pivot axes A and B. In the illustration in FIG. 2, the recess 62 is now also visible in the region of the first pivot axis A. In the illustration in FIG. 1, the recess 62 and the tread element 42 are covered by the vertical element 44.

An alternative form of the mobile unit 30 'is shown in FIG. Only the differences from the mobile unit 30 shown in FIGS. 1 and 2 will be discussed. In the mobile unit 30 'of FIG. 3, the folding stage 40' only comprises the pivot axis A 'and the tread element 42'. The pivot axis A 'is pivotally connected to the wall 50. This means that in the alternative shown, the tread element 42 'together with the swivel axis A' parallel to the wall 50, along the drawn direction Y, must be pulled up and swiveled away from the wall 50 about the swivel axis A 'in order to move the tread 40 " from the retracted position (on the left in Figure 3) to the unfolded position (on the right in Figure 3.) In the extended position, the recess 62 in the wall 50 is visible in the area of the first pivot axis A.

As an alternative to the swivel-slide movement described in connection with FIG. 3, the tread element 42 'shown in FIG. 3 can be arranged around a first swivel axis A (as in FIGS. 1 and 2) which is fixed between the wall 50 and the tread element 42' ) can be swiveled. In the case of only one swivel axis and in contrast to the alternative in FIGS. 1 and 2, a vertical element 44 is not necessary if the components are dimensioned accordingly.
