The arm rest can pivot between a first position and a second position. In the second position, a first clamping member 104 engages with a second clamping member 105, which is formed in a plate 102. After unlocking, a spring 107 loads the arm rest into the first position. Utility Model Content

[0004] The objective of this invention is to provide a transportation vehicle equipment component that further improves upon space requirements and a simpler structure.

[0005] The task is solved by a transportation vehicle equipment component having the features of this utility model.

[0006] According to this utility model, a transportation vehicle equipment component includes a base and a support shaft supported on the base for pivotally supporting a pivoting component. The pivoting component is pivotable between a first position and a second position about a first pivot axis formed by the support shaft, the first pivot axis being parallel to or the same as the central longitudinal axis of the support shaft. The pivoting component is latchable in at least one pivot position using a latching device. The support shaft has a first latching mechanism that is disengaged from a second latching mechanism of the pivoting component and is engaged in a manner that allows radial movement between the latched position and the disengaged position.

[0007] The transport vehicle equipment component has a base and a support shaft supported on the base for supporting basic components and pivoting components. The base, for example, is used to support the equipment component on the transport vehicle. The support shaft is, for example, fixedly supported relative to the base. Alternatively, the support shaft is pivotally supported relative to the base. The basic components are fixedly supported on the support shaft relative to it.

[0008] A support shaft forms a first pivot axis, which is generally parallel to or the same as the longitudinal axis of the support shaft. A pivoting member is pivotable relative to the support shaft about the first pivot axis between a first position and a second position. The pivoting member is latchable in at least one pivoting position using a latching device. The pivoting member is latchable, for example, in the first position and the second position, i.e., the final position. Alternatively, the pivoting member is latchable, for example, only in the second position. If the pivoting member, for example, is spring-loaded into the first position and moves against the spring force to the second position, then the pivoting member is latchable, for example, in the second position.

[0009] The support shaft has a first latching mechanism that can be disengaged from a second latching mechanism of the pivoting member and engaged in a locking configuration. The first latching mechanism is, for example, directly incorporated into the support shaft or the basic component. The first and / or second latching mechanisms are radially movable between a latched position and a disengaged position. This movement can be rotational, translational, or a mixture of these movements, comprising components of rotational and translational motion.

[0010] The pivoting component can be positioned relative to the base component and support shaft in different pivoting positions, such as a usable position and an inactive position, or a space-saving position and a comfortable position. In at least one position, the pivoting component can be latched and loaded by means of a latching device, without unintentionally changing its pivoting position. The latching device has at least one radially movable latching mechanism, which can be accommodated, for example, within the pivoting component in a space-saving manner. In this way, the transport vehicle equipment components can be manufactured with minimal cost.

[0011] The pivoting component is configured such that its surface extension is large with respect to its thickness. The pivoting component then has two large surfaces arranged opposite each other, and a small surface between the large surfaces along the pivoting direction.

[0012] If the transport vehicle equipment component is, for example, a handrail including an armrest, the armrest can be positioned in a first position where the surface normal of the smaller surface points in a defined direction, such as vertically upward. Based on the pivoting movement of the pivoting component, the surface normal of the larger surface points in a second position in a defined direction, such as vertically upward.

[0013] In the first position, the pivoting component has a small surface extension with respect to the horizontal plane. The extension in the vertical plane causes less interference to one or more seat occupants. Furthermore, the armrest—in the case of an armrest—can be better stored in the backrest in the first position. The gap in the backrest can then be narrower and thus less visually noticeable. In the case of two adjacent individual seats with vehicle equipment components in the form of armrests on opposite sides, for example, a wider aisle can exist in the first position than in the second position. Such aisles are particularly common in motorhomes or buses.

[0014] In the second position, which is, for example, a comfortable position, the pivoting component, such as an arm rest, has a large support or resting surface and may provide other features, such as a cup holder or space for electronic instruments, if necessary. The surface extension in the horizontal plane is larger than in the first position.

[0015] For example, a pivoting component can pivot between a first position and a second position at an angle of approximately 90°. In this case, the faces of the pivoting component that are perpendicular to each other can be alternately positioned in a defined direction, such that their surface normals point in a vertically upward direction.

[0016] The pivoting component is, for example, spring-loaded into a first or second position. In the context of this invention, each return element is referred to as a spring. After an active pivoting process by the user, the pivoting component automatically returns to a position spring-loaded upon force reduction or latch disengagement. If a position is a used position, for example, the movement of a transport vehicle equipment component is spring-loaded into a non-used position.

[0017] To facilitate the return to center during pivoting, every suitable spring is considered in principle. For example, the spring could be configured as a helical spring. In this case, it is possible to arrange the spring coaxially with the central axis of the support, thereby saving space.

[0018] For example, a spring-loaded return motion is cushioned by a damper. The movement of the pivoting component between the first and second positions thus appears to have higher quality. Furthermore, noise generated by the stop mechanism in the final position is prevented. Any suitable type of damper can be used.

[0019] The first latching mechanism, for example, has a latching gap with a support shaft. The latching gap is formed, for example, in a portion fastened to the support shaft or directly within the support shaft. The structure is particularly simple when the latching gap is formed directly within the support shaft. In this case, the latching gap can, for example, be formed integrally with the support shaft.

[0020] The second latching mechanism, for example, has a latching member that is radially movable. The latching member moves entirely within the pivoting member, for example. The latching member is movable, for example, translationally, rotationally, or by means of a mixture of translational and rotational components. The latching member is guided, for example, as a slider movably between a first and a second position within the housing of the pivoting member. The latching member, for example, has a protrusion that engages in a gap in the support shaft. According to an alternative, the latching member may also be movably held on the support shaft and the latching gap may be located on the pivoting member.

[0021] For example, the latch is loaded into the latched position by a return mechanism. The latching device is then automatically set into the latched position, for example, during manual release, and only needs to be manually adjusted to the disengaged position.

[0022] For example, the latching device can be adjusted between a latched position and a disengaged position by means of an operation. For example, the latching device, particularly the latch element, is spring-loaded into the latched position and can be adjusted to the disengaged position by means of the operation. Alternatively, the latching device can be set to the latched position and the disengaged position by means of an operation. In this case, the latching device is stably held in the latched position and the disengaged position.

[0023] In principle, the support shaft is either immovable or alternatively movable relative to the base. The support shaft may, for example, be pivotally supported on the base about a second pivot axis. In this case, the equipment component has other possibilities of movement. The equipment structural assembly, having a base component and a pivot component, can be adjusted relative to the base to different tilt positions. The equipment component can also, for example, pivotally rotate out of the seat occupant's movement area. If the equipment component is, for example, an armrest of a vehicle, the armrest with the base component and pivot component can be stored in the backrest gap in a non-use position. The base is used, for example, to secure the armrest to the vehicle seat.

[0024] The equipment component is, for example, an armrest having a base and an arm rest comprising a base and a pivoting component, which is either immovably or pivotally supported on the base. The base may, for example, be supported on the structure of a transport vehicle seat. Alternatively, the equipment component may be, for example, a table or support for operating components, having a base and a pivoting component and being immovably or movablely supported relative to the base.

[0025] Advantageously, the support shaft is either immovable or movable relative to the base.

[0026] Advantageously, the pivoting component is spring-loaded into a first position.

[0027] Advantageously, the return movement of the pivoting component from the second position to the first position is buffered by means of a buffer device.

[0054] The equipment components of the interior space of the transport vehicle, and in this example, the armrests for the seats of the transport vehicle, are indicated by reference numeral 10. Equipment component 10 has a base component 16 and a pivot component 12. The base component 16 and the pivot component 12 are supported on a support shaft 15, which... Figure 1Not shown in the diagram. The basic component 16 and the pivot component 12 together form the equipment structure assembly 17. In this example, the equipment structure assembly 17 is the arm rest of the armrest 10.

[0055] In this example, the base 11 is formed by a fastening protrusion 24, the geometric pivot axis a2 of which is perpendicular to the pivot axis a1 formed by the support shaft 15. The fastening protrusion 24, having a flange 25, is used to fasten the equipment component 10 to the vehicle seat. The pivot axis a1 is parallel to directions x1 and x2, and the pivot axis a2 is parallel to directions y1 and y2. Furthermore, directions z1 and z2 are shown in the figures, forming a normal coordinate system with directions y1 and y2 and x1 and x2.

[0056] The tilt position of the pivot member 12 can be adjusted by pivoting it about the pivot axis a2 in the direction p1 or p2. Tilting adjustment is known from the prior art and therefore is not described in more detail here. No diagram showing the tilt position is also provided. According to an alternative, the support shaft 15 may also be fixed relative to the base 11. Tilting adjustment is not available in this case.

[0057] The pivoting member 12 is pivotally supported relative to the base member 16 about the pivot axis a1 along directions u1 and u2. These features allow for adjustment of different usage positions for the pivoting member 12. In this case, the pivoting member 12 is... Figure 1 , 3 The first position shown in 5 and 7 to 11 and Figure 2 , 4 The second positions shown in 6 and 12 to 16 are movable relative to the base 11.

[0058] At least in the second position, the pivot member 12 can be latched. The pivot member 12 can be latched, for example, in both the first and second positions. In this example, the pivot member 12 is latched only in the second position. In this example, the pivot member 12 forming the armrest provides a larger abutment surface 14 in the second position than the abutment surface 13 in the first position, while the pivot member 12 requires less space in the first position with respect to directions y1 and y2.

[0059] However, alternatively in this example, the pivoting component 12 may also pivot for reasons other than providing a different resting surface. For example, by pivoting the pivoting component, an electrical or electronic operating switch or other functional element can be moved from a non-use position to a use position. These functional elements are, for example, optically inconspicuous and inaccessible in the non-use position, and accessible for operation in the use position. The defined position of the pivoting component 12 may also be well-suited for good storageability.

[0060] exist Figure 3 and 4 As can be seen from the comparison, the extension B1 of the abutment surface 13 along the y-direction is smaller than the extension B2 of the abutment surface 14 along the y-direction. In other words, the pivot member 12 occupies less space along the y-direction in the first position than in the second position. Therefore, the pivot member 12 provides a larger surface in the second position, on which an object or body part can be stored or supported. Figure 3 and 4 The base 11, which includes the fastening protrusion 24 and the flange 25, can also be seen in the image.

[0061] exist Figure 5 and 6 An opening 51 is visible in the middle, and a beverage holder (not shown) is disposed in the opening. The beverage holder is not shown in the overview.

[0062] Figure 7 A side view of the equipment component 10 is shown, in which the pivot component 12 is in a first position.

[0063] exist Figure 8 A cross-sectional view is shown, in which support shaft 15 is visible, on which pivot member 12 is supported. Support shaft 15 itself is pivotally supported on base 11 about pivot axis a2, thereby allowing adjustment of different tilt positions relative to base 11. Alternatively, support shaft 15 may be immovable relative to base 11. Support shaft 15 forms pivot axis a1. Spring 23 provided on support shaft 15 loads pivot member 12 into a first position. Housing 40 is also visible. Pad 18 is supported by housing 40. Pad 18 is covered by cover 19.

[0064] The housing 40 further has a guide wall 31, on which the latching member 21 of the latching device 20 can move along directions q1 and q2 during its movement between the latched and disengaged positions. In this example, the latching member 21 is chosen as an embodiment of the second latching mechanism 39. Other suitable latching mechanisms are also considered alternatively. A spring 32 loads the latching member 21 into the latched position along direction q1.

[0065] The latch 21 is operable via a lever 22 of the operating device 30, which is pivotally supported about a pivot axis a3 in directions v1 and v2. The lever 22 is therefore kinetically connected to the latch 21. By pivoting the lever 22 in direction v1, the latch 21 can be adjusted from the latched position to the disengaged position in direction q2. Based on the spring force of the spring 32, the latch 21 does not need to be actively adjusted from the disengaged position to the latched position in direction q1. The spring 32 causes the latch 21 to move automatically in direction q1. The kinetic connection between the latch 21 and the lever 22 results in the lever 22 pivoting back in direction v2 when the latch 21 moves in direction q1 to the latched position.

[0066] Latch 21 and latch 20 according to Figure 8 and 10 In the disengaged position, rotation of the pivot member 12 about the pivot axis a2 in the direction u1 is possible. The latching region 26 of the latch member 21—here the end face of the latch member—is in contact with the circumferential surface 27 of the support shaft 15. The defining surface 28 of the support shaft 15 rests against the side surface 29 of the latch member 21 so as to allow for rotation about the pivot axis a2. Figure 8 The position of the pivoting component 12 prevents further pivoting movement along the direction u1.

[0067] Furthermore, the movement of the latch 21 is buffered by the buffer 41. Based on the buffer 41, less noise is generated during the movement of the latch 21 due to the reduced movement speed. The movement of the pivot member 12 to the second position is performed by pivoting the pivot member 12 about the pivot axis 1 in the direction u1 until the latch 21 moves to engage with the latch gap 37 (see...). Figure 9 Therefore, a rotation of approximately 90° is required. The latch gap 37 is chosen here as an exemplary embodiment of the first latch mechanism 38 in the sense of this invention. Other suitable latch mechanisms are also considered.

[0068] The housing 40 has a gap 33 into which the user of the equipment component 10 can intervene. The lever 22 is configured as a double-arm lever. One lever arm 34 protrudes into the gap 33 and forms an operating protrusion 35. The other lever arm 36 of the lever 22 is connected to the latch 21. Actuation of the lever 22 in direction v1 causes the latch 21 to move to the disengaged position against the force of the spring 32. When the force on the operating protrusion 35 decreases, the spring 32 causes the latch 21 to move in direction q1. If the pivot component 12 is in the position according to… Figure 8 In the first position, the latch 21 is in contact with the circumferential surface 27 of the support shaft 15 and is held in the disengaged position against the force of the spring 32.

[0069] exist Figure 8As can be seen, latch 21 is not in the latched position, in which it engages with the gap in support shaft 15. Pivoting member 12 can therefore easily pivot in direction u1 toward the second position. In other words, lever 22 does not need to be manipulated for this purpose. Latch region 26 slides along circumferential surface 27 during the movement of pivoting member 12 between the first and second positions until it engages with latch gap 37.

[0070] In accordance with Figure 9 In the cross-sectional view, the first end region of the spring 23 can be seen, which is fixedly connected to the support shaft 15. The second end region is connected to the housing 40, so that the spring 23 is tensioned when the pivoting member 15 moves from the first position to the second position.

[0071] exist Figure 10 The pivot member 12 is shown in the support portion 42 on the support shaft 15. The housing 40 is disposed in the seat 44 of the support shaft 15 by means of a sliding bearing 43. (Relative to...) Figure 9 The diameter D1 of the support shaft 15 is according to Figure 10 The support shaft 15 has a smaller diameter D2 in the region of the support portion 42. Furthermore, in... Figure 10 The second end region of the spring 23 can be seen, which loads the pivot member 15 into the first position shown. The second end region is hook-shaped and surrounds the wall of the housing 40.

[0072] By following Figure 11 A longitudinal section of the equipment component 10 shows that the support shaft 15 extends from the base component 16 into the pivot component 12. Two support portions 42 of the support shaft 15 are visible. The spring 23 is also visible. The equipment component 10 has a support-side end region 45 and a free end region 46.

[0073] In this example, the equipment component 10 is also pivotable about the pivot axis a2. An operating portion 47, including a handle 48, is located on the free end region 46. The latching device 50, which is loaded into the latched position by a return device, can be unlocked using the operating portion 47.

[0074] Figure 12 A side view of the equipment component 10 in the second position is shown. A gap 33 with lever 22 can be seen, and this gap is well-accessibly positioned on the side 52 of the pivot component 12, allowing unlocking to occur in the disengaged position. A resting surface 14 with a large width B2 points in the second position of the pivot component 12 along direction z1. The surface normal of the side 52, including the gap 33 and lever 22, is oppositely positioned in the first position of the pivot component 12, pointing in the direction z2, so that it is optically inconspicuous to the user (see [link]). Figure 7 ).

[0075] If the pivot component 12 is in accordance with Figure 8 In the first position, pivoting approximately 90° along direction u1, the latch 21 overlaps with the latch gap 37 (see...). Figure 13 The latch 21 can be moved from the second position, loaded by the spring 32, along direction q1 and engaged with the latch gap 37, into the latch position. Figure 13 The latching region 26 engages with the latching gap 37, thereby hindering the movement of the pivoting component 12 with respect to the two pivoting directions u1 and u2.

[0076] Lever 22 can be followed Figure 13 To unlock, the lever 21 moves in direction v1, resisting the spring force of spring 32 in direction q2 to the disengaged position. The pivoting member 12 can then be pivoted back in direction u2 by spring 23. As the force on the operating protrusion 35 of lever 22 decreases, the latch 21 is loaded by spring 32 in direction q1, causing the latch to rest against the circumferential surface 27 with the latching region 26. Lever 22 pivots back in direction v2.

[0077] Figure 14 The cross section is shown through the equipment component 10 along the section line FF.

[0078] By following Figure 16 A longitudinal section of the equipment component 10 reveals the support shaft 15, lever 22, and latch 21 in the area of ​​the support portion 42, and the housing 40 in the second position of the pivot component 12. A buffer 49 cushions the movement of the pivot component 12 between the first and second positions.
