    The invention relates to a table for a vehicle, wherein the table has at least one base for attachment to the vehicle, as well as a tabletop connected to the base, and wherein the table top is elastically movable via a connecting device with respect to the base transverse to a longitudinal axis of the table ,
    In vehicles, especially rail vehicles, it is common for passengers
    To arrange tables, which are normally assigned a total of four seats. There are usually two seats next to each other in the direction of travel and two opposite directed against the direction of travel and arranged the table in between. Accordingly, the longitudinal axis of the table is usually aligned transversely to the direction of travel of the vehicle.
    In this case, the direction of travel is the main direction of travel of the vehicle, in which the vehicle usually moves in the main. In most cases, the direction of travel is parallel to the longitudinal axis of the vehicle.
    To protect the passengers who sit on the seats in the direction of travel, the table may have an energy absorption mechanism. When strong accelerations occur, for example in the case of emergency braking or a collision, the kinetic energy of the passengers impacting on the table is at least partially absorbed and their risk of injury is reduced.
    EP 2 956 347 B1 describes a table with plastically deformable
    Connecting elements that deform plastically in an impact and thus absorb energy. However, this is unfavorable, since after such an incident essential parts of the table must be replaced in order to make it functional again. The associated work is complex and expensive.
    US 2012/0132767 A1 shows an improved system having resiliently movable connecting arms and rods extending from the base vertically to the table top. As a result, the destruction of the parts during emergency braking is prevented. In addition, the risk of injury is further reduced. The disadvantage, however, is that there is bruising of body parts of the / 15
    Passengers can come as the height of the table top changes during movement.
    The object is to provide a table of the type mentioned, which has a reduced risk of injury to passengers when strong accelerations occur. It should occur up to a certain load limit only a reversible deformation, that is, that the table automatically returns to its original position.
    This object is achieved in that the
    Connecting device has at least one, extending substantially along the longitudinal axis, elastic connecting beam, via which the table top is connected to the base.
    By such an arrangement of a connecting bar, a purely or predominantly horizontal movement of the table top can be achieved. This reduces the risk of injury to the passenger. The arrangement is particularly advantageous because the connecting bar can be placed directly below the table top, which saves space and it is better protected against damage or vandalism.
    Direction or orientation information as above or horizontally related to a proper installation position of the table in a vehicle.
    The connection device may have, beyond the connecting beam, further elastically deformable elements which improve the energy absorption. These elements can be connected serially to the connection bar or parallel to it.
    It is particularly advantageous when the base is firmly connected to a substantially extending along the longitudinal axis base and the table top is arranged to be elastically movable on the base. The substructure can be designed so that the connecting beam can be arranged therein - protected against unauthorized manipulation. The table top can be movably mounted on the base and resting on it. In this case, the base and the base can also be made in one piece. Preferably, the substructure is made transverse to the longitudinal axis less wide than the table top. This allows a movement of the / 15
    Table top transverse to the longitudinal direction, even if it projects beyond the substructure at its side edges at least partially.
    It can further be provided that the connecting beam is connected at its ends to the table top and is connected to the base in a middle fastening region between the ends. Here is the middle one
    Attachment area preferably connected to the substructure, if provided. This is particularly advantageous because it allows both sides of the table top can be well sprung. This is especially important in the case of tables with two seats for one person on one side. If both places are taken and both persons hit the same side of the table in a collision, then both halves of the table top move in substantially the same direction. If the people are the same weight, then it comes to about a parallel displacement of the table top. If only one seat is occupied, then there is a rotation of the table top.
    In a preferred embodiment it is provided that the connecting device has at least one elastically deformable secondary element. This secondary element may, for example, be designed as a preferably spring-loaded shock absorber and cooperate with the elastic deformation of the connecting beam, for example by damping it.
    It can further be provided that the elastically deformable secondary element is connected in parallel with the connecting beam between the table top and the base. In this case, it is meant that at least two communication paths exist between the tabletop and the pedestal: one via the connecting bar and one via the secondary element. Thus, the elastic deformations of these two deformable components act in parallel and not serially. Alternatively, they can also be connected in series with one another. The secondary element does not have to absorb energy over the entire movement space of the tabletop. It can also be provided, for example, that the secondary element has an open circuit and receives energy only from a certain degree of displacement between the table top and base.
    If it is provided that the secondary element has two mutually elastically displaceable end pieces and these end pieces are supported on two opposite bearing surfaces of the substructure, and that at least / an end piece is at least one support piece with the table top in combination, the table top can be mounted movable while the secondary element absorbs energy. If at least one support piece is provided on both end pieces, then the table top can be supported elastically movably in two directions. The bearing surfaces are preferably arranged opposite each other along an axis, wherein the axis is transverse to the longitudinal axis. The connection with the tabletop does not have to be in all positions of the tabletop for the overlay. Upon movement of the table top in one direction, a first end piece is pressed in the direction of the second end piece via a support piece, which rests on the support surface and is supported thereon. When moving in the opposite direction, the pad, which is connected to the second end piece, is pressed in the direction of the first end piece, which in turn rests on the other bearing surface.
    It is particularly advantageous if one connected to the table top
    Connecting piece is arranged transversely to the longitudinal axis in front of or behind at least one bearing piece connected to the secondary element and that in the unloaded state of the table top, the connecting piece is spaced from the support piece. As a result, the table top is opened a range of motion in which the secondary element does not deform elastically. Preferably, however, at least partially an elastic deformation of the connecting bar occurs in this area. Only with a movement beyond this scope, an elastic deformation of the secondary element occurs.
    It may be provided that a support piece is arranged transversely to the longitudinal axis on both sides of the connecting piece and in the unloaded state spaced. As a result, the elastic deformation of the secondary element can take place when the range of motion is exceeded in both directions. This is particularly advantageous since in particular train wagons are often guided along their main axis in both directions. It is irrelevant in which direction the table is installed, since it is elastically deformable in both directions.
    It is space-saving if the at least one connecting piece is arranged on at least one end of the connecting bar. Thereby, the connector can be used dual for connection to the connecting beam and for connection to the secondary element.

    If the connecting beam has at least one leaf spring, preferably designed as a leaf spring package, so that a good elastic mobility can be achieved. The leaf spring is preferably arranged so that the resilient main direction of action in the intended installation position is transverse to the longitudinal axis and substantially horizontal. The advantage of a leaf spring package lies in the inherent damping, which is advantageous in terms of energy dissipation.
    It is particularly advantageous if the table top along the longitudinal axis substantially centrally has a connecting pin which is connected to a carriage of the substructure, and that the carriage is transverse to the longitudinal axis movable to the substructure. This allows a movable mounting of the table top transverse to the longitudinal axis. The carriage may be elastically movable, for example, be sprung or mainly serve to guide the table top and not contribute or only to a very minor extent to the energy intake.
    If it is provided that the substructure has at least one friction element which is sprung against the table top, additional damping of the movement of the table top to the substructure can be achieved.
    It can be provided that the substructure has at least one table leg which can be connected to a vehicle floor. This allows a particularly good connection with the vehicle. Depending on the length of the leg, the table can be fixed at different heights.
    It is particularly advantageous if the base is connectable to a vehicle wall of the vehicle. In particular, the lateral attachment to a side wall of the vehicle is advantageous.
    In the following, the present invention will be explained in more detail with reference to a non-limiting embodiment shown in the figures. Show it:
    1 shows an embodiment of a table according to the invention in a mounted position in a vehicle of a schematic oblique view;
    Figure 2 is an exploded view of the base of the embodiment of Fig. 1;
    / 15
    Figure 3 shows a detail of the substructure in a plan stitch.
    Fig. 1 shows a table 1 according to the invention with a substantially rectangular table top 2 and a base 3. The table 1 is arranged in a partially illustrated vehicle, here a train wagon, on a vehicle side wall 100 of the vehicle. A longitudinal axis A of the table 1 extends parallel to the longer side edges 4 of the table top 2 and is transverse to a direction of travel 101 of the vehicle. The base 3 has a substantially vertical, applied to the vehicle side wall 100 wall portion 5 and a base 6 directly below the table top 2. The table top 2 projects beyond the side edges 4 the substructure 6 sections and thus forms on each side two common impact surfaces 7. On both side edges 4 of the table top two seats 102 are arranged, two in and two against the direction of travel 101. In this case, the impact surfaces arranged along the direction of travel 101 directly in front of the seats 102 and thus provide a larger area at which passengers can bounce on the table 1 in the event of a collision.
    At the height of the table top 2, the wall part 5 on the vehicle side wall 100 a pointing to the table top 2, slightly rounded area on which abuts a broad edge of the table top 2. This broad edge also has a coordinated, rounded shape. If only one of the seats 102 is occupied in the direction of travel and if there is a collision, then the table top 2 can rotate more easily with respect to the base 3 without damaging the base 3 or the tabletop 2.
    In Fig. 2, the base 3 is shown in an exploded view. For clarity, some components such as screws were not or only partially shown. The wall part 5 of the base 3 is made of high-strength steel and / or aluminum and mainly fulfills the task of static support of the table 1. It consists of a voltage applied to the vehicle wall 100, the contour of the vehicle wall 100 corresponding plate, and side panels. The base 6 has a shell 8 made of steel plates and / or aluminum plates, wherein on the side facing the table top 2, two apertured shell plates 9 are arranged. In the interior of the substructure 6, a connecting device 10 is arranged, which has a connecting beam 11, which is designed as a leaf spring package, extending substantially along / 15 of the longitudinal axis A and is shown in an unloaded state.
    The surfaces of the leaf springs in or against the direction of travel, so the elastic deformation is best possible in or against the direction of travel. These bends transverse to the longitudinal axis A and thus in or against the direction of travel are schematically indicated by lines 21.
    Centered along its length, the connecting bar 11 has a
    Attachment area 12 which is fixedly connected to a crossbar 13 of the base 6. At the ends of the connecting bar 11 connecting pieces 14 are arranged with pointing to the table top 2 slots. The elongated holes extend in the unloaded state of the connecting bar 11 along the longitudinal axis A and thus along the length of the connecting bar 11. Connecting pins of the table top 2 can engage in these slots and thus make a connection. The leaf spring package is held together with a total of four brackets, two on each side of the connecting bar 11. The brackets are movably arranged on the leaf spring assembly. The brackets are held together by a fabric strip which acts as a positioning aid and is connected to both the brackets and the crossbar 13 and the connectors 14.
    The crossbar 13 has a guide, in which a transversely to the longitudinal axis A movable carriage 15 is arranged. This has an opening into which a connecting pin of the table top 2 can engage. Preferably, the connecting pin is arranged centrally on the table top 2.
    At the ends of the substructure 6 a respective spring rod 16 is provided, which are spring-loaded pressed in the direction of the table top 2. The shell plates 9 have through openings 17, through which the spring rods 16 can be pressed onto the underside of the table top 2. The spring bars 16 are coated on their upper side with a rubbing layer, such as a felt layer, which dampens the movements of the table top 2. This rubbing layer can also be arranged on the underside of the table top 2. Thus, the spring bars 16 act as friction elements. At the ends of the substructure 6 along the longitudinal axis A, a secondary element 18 is also arranged, which extends substantially transversely to the longitudinal axis A. They each have two end pieces 19a, / 15
    19b in the form of pins, which bear against bearing surfaces of the shell 8 of the substructure 6 transversely to the longitudinal axis A.
    In Fig. 3, the operation of the connecting device 10 can be seen. For this purpose, one of the shell plates 9 was not shown. On each end piece 19a, 19b, a respective support piece 20 is attached, which is constructed S-shaped, and from the end piece 19a, 19b, with which it is in communication, on the side of the
    Secondary element 18 extends over half the length of the secondary element 18. The support pieces 20 have openings for this, in which the pin-shaped end pieces 19a, 19b can engage (shown in Fig. 2). The connecting pieces 14 have, on the sides facing the secondary elements 18, anchors 22 which, in the unloaded state of the table top 2, do not touch the attack hooks 23 of the support pieces 20. The connector 14 and armature 22 are integral and the attack hooks 23 and support members 20 are also made in one piece. These support pieces 20 are arranged along the longitudinal axis A at the level of the attack hooks 23 but spaced from these. If the table top 2 is moved in a direction B, for example by the impact of up to two passengers, then the connecting beam 11 is elastically bent in precisely this direction. With only slight bending, the secondary elements 18 remain unchanged. If the bending is so strong that the anchors 22 each reach one of the engagement hooks 23, which are connected to first end pieces 19a, then the connection between the table top 2 and the secondary element 18 is closed. The first end pieces 19a are thereby pressed in the direction of the second end pieces 19b, which rest against the base 6 and are not movable. This results in the further movement of the table top 2 to an elastic deformation of the secondary elements 18. Thus, in addition to the connection via the connecting bar 11 in parallel to a further energy receiving connection between the table top 2 and base 3 is created. In the movement of the table top 2 in the opposite direction, the connecting device 10 behaves substantially analogously, wherein the attack hooks 23 are used, which are in communication with the second end pieces 19b.
    If only one person bounces eccentrically on the table top 2, it comes through the unequal application of force to a rotation of the table top 2 or a superimposed movement of rotation and displacement.
    / 15
    The secondary element 18 is constructed in two parts as internally sprung shock absorbers.
    The embodiment described in the figures is designed for a 4-person seating opportunity, so that therefore two people sit in and two people against the direction of travel at the table. In an alternative embodiment, it can be provided that only one person sits in and one person counter to the direction of travel. Accordingly, the table is made smaller, wherein preferably substantially the same technology can be used, optionally with appropriate adaptations and adjustments. In this case, only one half of the table can be performed, so that the crossbar 13 is disposed on the vehicle side wall 100 and the connecting bar 11 extends only in one direction from the crossbar 13 from. Accordingly, preferably only one secondary element 18 would then be provided. Alternatively, the same internal structure as shown in the figures can be provided, but along the side edges 4 in a shorter embodiment, so that only one seat is arranged on each side edge 4. In principle, it is also possible to prefer tables with more than two seats in the direction of travel, ie with three or four seats.
