[0001] The invention relates to an arrangement of a collapsible table in the interior of a motor vehicle, having a table top, which is arranged on a vehicle-mounted carrier such that it can be transferred from a rest position, with an essentially vertically oriented table plane, into an essentially horizontally oriented, use position, wherein the carrier extends in the longitudinal direction of the vehicle and the table top is fastened on the carrier by means of a table-top holder such that it can be pivoted, about a pivot axis extending in the longitudinal direction of the vehicle, out of its vertical, rest position into a horizontal position, and wherein the table top and/or the table-top holder can be arrested in the use position by means of an arresting device, which is a latching device into which, with the table top located in the horizontal position and/or in the vertical position, the table-top holder can be latched.
[0002] DE 101 14 837 A1 and DE 102 30 643 A1 disclose an arrangement of a collapsible table which corresponds largely to the type mentioned in the introduction.
[0003] DE 100 44 414 A1 discloses an arrangement of a collapsible table which is arranged above a supporting panel on a pull-out carrying arm. In the pulled-out state, the table, which comprises two panel elements, can be swung open transversely to the longitudinal direction of the vehicle. There is no arresting device present.
[0004] DE 10 2006 043 483 A1 discloses an aircraft-seat mechanism with a table which is arranged on a multiple-pull-out-mechanism arm such that it can be pivoted out of a vertically upwardly directed, rest position into a horizontal, use position. This arrangement can be fixed by latching means in the various carrying positions.
[0005] It is an object of the invention to provide an arrangement of the type mentioned in the introduction in the case of which the table can be stored in a space-saving manner in its rest position and has a straightforward and stable construction.
[0006] This object is achieved according to the invention in that the table-top holder, with the table top located in a horizontal position and/or in a vertical position, is mounted in a displaceable manner in or counter to the direction of travel such that it can be latched into a latching recess of the carrier, this recess extending in or counter to the direction of travel, and is secured against pivoting about the first pivot axis.
[0007] The vertical arrangement in the rest position means that only a small amount of space is required for accommodating the table top.
[0008] In its use position, the table top is secured in a stable manner since it is fixed not just via the pivot axis but, in addition, also by the arresting device.
[0009] Biasing the table-top holder in the latching-in direction into the latching recess means that, once the table top has been swung into its horizontal orientation, the table top is automatically fixed in the use position.
[0010] The table top is also secured in the rest position in that the table top and/or the table-top holder can be arrested in the rest position by means of an arresting mechanism.
[0011] It is possible for the table-top holder to have a bearing lug with a bearing bore extending in the longitudinal direction of the vehicle and to be mounted, by way of the bearing bore, such that it can be pivoted on a bearing spindle, which extends coaxially to the pivot axis and is arranged on the carrier.
[0012] This design allows the bearing spindle to be arranged at a fixed location, which results in stabilization of the table top located in the use position, and therefore this table top can also be subjected to relatively high loading.
[0013] If a helical compression spring here wraps around the bearing spindle with play, wherein the helical compression spring has its one end supported on the carrier and has its other end prestressed in abutment against the table-top holder, biasing the latter in the latching-in direction into the latching recess, then only a small amount of installation space is necessary.
[0014] A further reduction in the amount of installation space necessary is achieved by the carrier being designed in the manner of a tube with an inner recess, wherein the bearing spindle extends coaxially through the inner recess and the table-top holder has its bearing lug projecting through a radial opening into the inner recess of the carrier.
[0015] A straightforward construction and low weight are achieved here if the carrier is designed as a sheet-metal part bent in the form of a U or as a quadrilateral tube. These two structural forms, inter alia, will be referred to hereinbelow as tubular.
[0016] If, furthermore, the latching recess is a latching slot which extends from the radial opening of the carrier in or counter to the direction of travel, then the table top is secured, in addition, against tilting away laterally.
[0017] Furthermore, the table top may be mounted on the table-top holder such that it can be rotated about a table-top axis of rotation extending at right angles to the plane of the table top.
[0018] It is thus possible for the table top, while maintaining its stability, to be pivoted with a large degree of freedom into various positions, in particular also into a position in front of the carrier, as seen in the direction of travel.
[0019] In order to achieve, in the use position, a large bearing surface area for the table top while, at the same time, only a small amount of stowage space is required in the rest position, it is possible for the table top to comprise two table sub-tops, wherein a first table sub-top is arranged on the table-top holder and is connected along a longitudinal edge, by means of a hinge, to a longitudinal edge of the second table sub-top.
[0020] If the carrier is an armrest, then this results, with a double function, in only a small amount of installation space being required.
[0021] The armrest here may be arranged on a seat of the motor vehicle.
[0022] If the armrest is arranged between the driver's seat and the passenger seat, then the table top can be used both by the driver and by the passenger.
[0023] It is possible for the armrest to have its rear end region, as seen in the direction of travel, arranged on a backrest of a vehicle seat such that it can be pivoted about an armrest spindle extending at right angles to the longitudinal extent of the armrest.
[0024] If an inclination-adjusting shaft, which is mounted in a rotatable, but axially non-displaceable manner, extends axially through the inner recess of the armrest, projects outward at the front end of the armrest, as seen in the direction of travel, and carries a rotary knob, wherein the inclination-adjusting shaft, at its other end, is provided with an external thread which engages in an inclination-adjusting device for adjusting the inclination, in the direction of travel, of the armrest, then the inclination of the armrest can be adjusted by manual rotation of the rotary knob. It is thus possible, upon adjustment of the inclination of the backrest, for the armrest, which is articulated thereon, to be moved into a horizontal orientation, and therefore the table, which is fitted on the armrest, can also be oriented horizontally.
[0025] It is possible here for the bearing spindle and the inclination-adjusting shaft to extend parallel to one another through the inner recess of the armrest.
[0026] In a manner which reduces the number of components and the amount of installation space required, however, it is also possible for the bearing spindle and inclination-adjusting shaft to form a single component, which performs the double function of the bearing spindle and inclination-adjusting shaft.
[0027] An exemplary embodiment of the invention will be described in more detail hereinbelow and is illustrated in the drawing, in which:
[0028] FIG. 1 shows a first perspective view of a first exemplary embodiment of an arrangement of a collapsible table in the rest position,

[0035] FIG. 8 shows a perspective view of the table top of the arrangement according to FIG. 1,
[0036] FIG. 9 shows a perspective view of a basic-panel arrangement of the table top according to FIG. 8,
[0037] FIG. 10 shows an enlarged detail "IX" of the basic-panel arrangement according to FIG. 9,
[0038] FIG. 11 shows a perspective view of a second exemplary embodiment of an arrangement of a collapsible table in a use position with the table top swung open,
[0039] FIG. 12 shows a perspective view of an armrest of the arrangement according to FIG. 11 with a table-top holder, and
[0040] FIG. 13 shows a perspective view of the armrest according to FIG. 12 without a table-top holder.
[0041] The illustrated arrangement of a collapsible table has a carrier which is designed as an armrest 1, 1'.
[0042] The armrest 1, 1' can preferably be arranged between a driver's seat and a passenger seat of a motor vehicle and extends in the longitudinal direction of the vehicle.
[0043] At its rear end region, as seen in the direction of travel 11, the armrest 1 of FIGS. 1 to 10 has an armrest spindle 2 which extends at right angles to the longitudinal extent of the armrest 1 and by means of which the armrest 1 is arranged such that it can be pivoted on a backrest (not illustrated) of the passenger seat.
[0044] The armrest 1 has a sheet-metal part 3 which is bent in the form of a U, is closed on its open side by a covering plate 32 and has an axially continuous inner recess 4, which is closed at its two ends by closure pieces 5. The front closure piece 5, here, as seen in the direction of travel, is formed by a bent-over part of the sheet-metal part 3 bent in the form of a U.
[0045] In FIGS. 11 to 13, the armrest 1' is formed by a sheet-metal part 3' which is bent in the form of a U, has an axially continuous recess 4' and is closed at its axial ends by integral closure pieces 5'.
[0046] An inclination-adjusting device 33 is arranged in the rear end region of the armrest 1', as seen in the direction of travel 11. By means of the inclination-adjusting device 33, the armrest 1' can be adjusted in inclination in the direction of travel about an inclination-adjusting spindle 34 extending at right angles to the armrest 1'.
[0047] The inclination-adjusting spindle 34 projects out of the armrest 1' and is connected to a plate 35 which, in turn, is arranged pivotably on a backrest (not illustrated) of the passenger seat such that it can be pivoted via an armrest spindle 2', which is parallel to the inclination-adjusting spindle 34.
[0048] Instead of the sheet-metal part 3 which is bent in the form of a U, and has the covering plate 32, it is also possible to use a quadrilateral tube.
[0049] In FIGS. 1 to 10, a bearing spindle 6, which forms an inclination-adjusting shaft at the same time, projects coaxially through the inner recess 4 and is mounted in a rotatable, but axially non-displaceable, manner in the two closure pieces 5.
[0050] In FIGS. 11 to 13, a bearing spindle 6' and an inclination-adjusting shaft 36 project axially, parallel to one another, through the inner recess 4'. The bearing spindle 6' here has its one end fixed on the front closure piece 5' and has its rear end fixed on an intermediate wall 36.
[0051] The inclination-adjusting shaft 36 is mounted in a rotatable manner in the front closure piece 5' and has its externally threaded rear end region projecting into the inclination-adjusting device 33.
[0052] The bearing spindle 6 or the inclination-adjusting shaft 36 projects outward at the front closure piece 5, as seen in the direction of travel 11, through a continuous bearing bore and carries, at this free end, a rotary knob 7, by means of which the bearing spindle 6 or the inclination-adjusting shaft 36 can be rotated.
[0053] At its other end, the bearing spindle 6, like the inclination-adjusting shaft 36, is provided with an external thread.
[0054] Manual rotation of the rotary knob 7, and thus of the bearing spindle 6 or of the inclination-adjusting shaft 36, makes it possible to actuate the inclination-setting and/or length-setting mechanism 33 of known type (not illustrated in FIGS. 1 to 10), as a result of which it is possible to set, in particular, the inclination of the armrest 1.
[0055] It is thus possible, upon adjustment of the inclination of the backrest, for the armrest 1, which is articulated thereon, to be moved into a horizontal orientation, and therefore a table, which is fitted on the armrest 1, can also be oriented horizontally.
[0056] In the case of both exemplary embodiments, the one side wall 9 of the sheet-metal part 3 bent in the form of a U contains a rectangular radial opening 8 extending from the side wall 9 into the base wall 10 of the sheet-metal part 3 bent in the form of a U.
[0057] In continuation of the upper edge of the radial opening 8, a latching slot 12 extends into the side wall 9 counter to the direction of travel 11.
[0058] An arm 13 of a table-top holder 16, this consisting of a flat material bent approximately in the form of a U, projects through the radial opening 8.
[0059] A bearing lug 14 with a continuous bearing bore 15 is arranged at that end of the arm 13 which projects into the inner recess 4 of the sheet-metal part 3 bent in the form of a U, the table-top holder 16 being guided in a pivotable and displaceable manner on the bearing spindle 6 by means of this bearing bore.
[0060] The pivotability of the table-top holder 16 means that the arm 13 thereof can be pivoted between a position in which it projects horizontally to the side and a position in which it projects vertically downward.
[0061] With the arm 13 located in the horizontal position, it can be moved, by axial displacement of the table-top holder 16, into the latching slot 12, as a result of which the table-top holder 16 is secured against pivoting in the use position.
[0062] This movement into the latching slot 12 takes place automatically and by way of a prestressed helical compression spring 17 which wraps around the bearing spindle 6 with play and has its one end supported on the front closure piece 5, as seen in the direction travel 11, and has its other end supported on the bearing lug 14 of the table-top holder 16.
[0063] In continuation of the lower edge of the radial opening 8, a second latching slot (not illustrated) extends into the base wall 10 counter to the direction of travel 11. With the arm 13 located in the vertical position, it can be moved, by axial displacement of the table-top holder 16, into the second latching slot, as a result of which the table-top holder 16 is secured against pivoting in the rest position. The movement into the second latching slot also takes place by way of the helical compression spring 17.
[0064] As an alternative, it is also conceivable for the latching slot 12 and the second latching slot (not illustrated) to be arranged to extend in the direction of travel 11. In this case, the helical compression spring 17 should be arranged such that it forces the table-top holder 16 in the direction of travel.
[0065] The second arm 18 of the table-top holder 16, this second arm being parallel to the arm 13, has a second bearing bore 21, which is directed parallel to the base part 20 of the table-top holder 16, this base part connecting the arm 13 and the second arm 18, and in which a table top 22, which rests on the second arm 18 and is connected thereto, is mounted such that it can be rotated about a table-top axis of rotation 19.
[0066] The table top 22 comprises two table sub-tops 23 and 24, wherein the first table sub-top 23 is connected along a longitudinal edge, by means of a hinge 25, to a longitudinal edge of the second table sub-top 24 such that the second table sub-top 24 can be pivoted out of a collapsed position, in which it butts with surface contact against the first table sub-top 23, into a swung-open position, in which it is pivoted through 90°.
[0067] The second bearing bore 21 is located, in FIGS. 1 to 10, in a corner of that region of the first table sub-top 23 which is directed away from the hinge 25.
[0068] In FIGS. 11 to 13, the second bearing bore (not illustrated) is located in the central peripheral region of the first table sub-top 23.
[0069] The two table sub-tops 23 and 24 comprise basic panels 28 and 29 which are made of metal and are connected to one another by the hinge 25.
[0070] On the side which is directed upward in the use position, the basic panels 28 and 29 are covered by cover panels 30 and 31 made of a plastics material.
[0071] In the rest position of the arrangement, this position being illustrated in FIG. 1, the table top 22 is collapsed and oriented vertically parallel to the armrest 1.
[0072] For transfer into the use position, the table top 22 is pivoted forward, in the first instance corresponding to the arrow 26 in FIG. 1, about the axis of the second bearing board 21 into the position which is illustrated in FIG. 3.
[0073] Pivoting then takes place about the bearing spindle 6, corresponding to the arrow 27 in FIG. 3, until the table top 22 has its table plane oriented horizontally (FIGS. 4 and 6).
[0074] The force of the helical compression spring 17 then causes the table-top holder 16 to be moved, by way of its arm 13, into the latching slot 12 (FIG. 5).
[0075] All that is then required is for the two table sub-tops 23 and 24 to be swung open, and the arrangement is located in its use position (FIG. 11).
