Description

Tischvorrichtunq

The invention relates to a table device of a vehicle seat, in particular of a passenger seat, according to the preamble of patent claim 1 and a vehicle seat, in particular a passenger seat, with such a table device.

Table devices of vehicle seats are already known which have at least one sloped surface and a bearing unit. The bearing unit is intended to guide the at least one abutment surface during a movement between at least one use position and at least one first stowage position. In known embodiments, the table device is arranged on a rear side of a backrest of a vehicle seat. In the use position of the Absteilfläche this is a passenger who usually uses a second passenger seat mounted there in a rear space of the passenger seat available for use. For storage in the stowed position, the storage area can be applied to the back of the backrest of the passenger seat by a pivoting movement of the storage unit and fixed in the stowed position with a locking device, for example a rotatably mounted toggle button. Unfortunately, the locking device occupies a relatively large space in a spatial area of the passenger seat which is increasingly used for arranging screens for providing entertaining or informative image contents to passengers. In addition, elements of the locking device in the stowage position of the parking area in the event of an impact event often pose a risk, in particular for headboards of the passengers, since they often come from the back of the

CONFIRMATION COPY Protruding backrest of the passenger seat and are in the event of an impact event directly in an impact area of the head sections.

The invention is in particular the object of providing a table device and a vehicle seat with a table device, through which the safety of the passengers and ease of use for the passengers can be increased.

This object is achieved by a table device according to claim 1. Further advantageous embodiments of the invention can be taken from the dependent claims.

Advantages of the invention

The invention relates to a table device of a vehicle seat, in particular a passenger seat, which has at least one Absteilfläche and a bearing unit which is intended to guide the at least one Absteilfläche in a movement between at least one use position and at least a first storage position.

It is proposed that the table device has a locking unit which is provided to use a substantially parallel to the shelf surface extending movement of the shelf as a locking movement. Preferably, the movement can take place from the first storage position. In this context, "parallel to the storage area" is to be understood in particular as meaning that the storage area in the first stowed position forms part of a first level and the storage area forms a part of the first level or a part of a second level after movement has taken place In this context, the term "substantially parallel" should be understood to mean, in particular, that after the movement of the storage surface the storage surface is aligned parallel to the first plane or an intersection angle, below which the first plane and the second plane cut, less than 30 °, preferably less than 20 ° and more preferably less than 15 °.

In a suitable embodiment can be dispensed with arranged in a Kopfaufschlagbereich the vehicle seat holding means of the locking unit, whereby the security passengers can be increased. Furthermore, a solution with improved design freedom may be provided with respect to a layout of a passenger entertainment device or information device, such as a display screen, as part of an in-flight entertainment (IFE) system in an aircraft-type vehicle. A height of a backrest of a passenger seat designed as a passenger seat can be reduced with an equally large screen of the IFE device and thereby material and costs can be saved.

Furthermore, it is proposed that the locking unit has a lifting unit for lifting at least the storage area by the movement of the storage area extending substantially parallel to the storage area from the first storage position into a second, locked storage position. In this context, "lifting" should be understood to mean, in particular, carrying out a movement which has at least one component in a direction opposite to gravity, thereby enabling a simple and space-saving design of a locked stowage position without holding means in the head impact area of the vehicle seat.

If a region of the storage area near the edge forms a corresponding partial element of a form-locking connection in one of the stowed positions, a structurally simple and reliable mounting of the storage area can be achieved without holding means in the head impact area of the vehicle seat. In a suitable embodiment, in the event of an impact event, a passageway which is less dangerous for the passenger and thus more favorable can be provided at the area near the edge of the parking area in the impact area of the headspace of the passenger.

Furthermore, it is proposed that the lifting unit has at least one flexurally soft traction means, by the extension of which the storage area can be brought into the second, locked stowage position by the movement of the depositing surface extending substantially parallel to the depositing surface. A "bendable" traction means should in particular be understood to mean a traction device which can not absorb any force in at least one direction which deviates from a direction of the main extension of the traction means, such as a link chain, a wire, a cord or a belt In particular, the direction may be transverse to the longitudinal extent of the traction means, thereby providing a simple and inexpensive solution to the problem Shipment of the storage space can be achieved. Preferably, the extension may be provided so that a length of the traction means between an attachment point of the traction means and a point of force application of the traction means on the shelf or on a rigidly connected to the shelf body after the extension is changed. Alternatively, the stretching may be provided in a manner in which the traction means is rectilinear before stretching and at least in part rectilinearly after stretching.

In a further advantageous embodiment, it is proposed that the lifting unit has at least one rigid support body which is provided for lifting the storage area from the first storage position to the second, locked storage position. In a suitable embodiment, a simple solution of a locked storage position of the storage area without holding means in the impact area of the head sections of the passenger can be made possible thereby. Preferably, the lifting of the shelf may be provided by a change in a relative position of the rigid support body with respect to the shelf.

In a further embodiment, the at least one flexurally soft traction means can be brought into contact with the at least one rigid support body in a particularly advantageous manner, as a result of which a particularly simple and cost-effective solution for transferring the storage surface can be achieved.

If the table device comprises at least one further support body which is formed by a stiffening means provided for a stiffening, by transferring a function of the at least one further support body to the stiffening means already present in a design and necessary for an intended function of the table device Reduced number of components and it can cost, material and weight can be saved. It is also proposed that the at least one support body is rotatably mounted in the storage area. As a result, a particularly simple solution of a locked stowage position of the parking area without holding means in the impact area of the head sections of the passenger can be provided. Particularly advantageously, in a further embodiment, the at least one support body mechanically connected to the at least one traction means and the length of the traction means between an attachment point of the traction means and the support body by rotation of the rotatably mounted support body be changed, whereby the Abstell- surface in a simple manner the first stowed position can be brought into the second, locked stowed position.

If the at least one support body is mounted eccentrically in the Absteilfläche, a support movement can be made possible with a suitable embodiment in a particularly simple manner

In addition, it is proposed that the locking unit has at least one locking means for fixing the Absteilfläche in the second, locked storage position. In this context, "latching means" are to be understood as meaning, in particular, means intended to form a form-locking connection upon relative movement into a predetermined arrangement, overcoming a force opposing the relative movement, which is releasable only upon application of at least the counteracting force As a result, confirmation of completion of the locking movement for the operator to increase the ease of operation and conditional protection against inadvertent unlocking of the table device can be achieved.

Improved protection against the unintentional unlocking of the table device, which is caused, for example, in an airplane by turbulences or in a bus due to uneven road surfaces, can be achieved if the locking unit has at least one securing means for securing the shelf in the second, locked stowed position.

It is also proposed that the locking unit has a lowering means which is provided to lower the storage area from the second, locked stowed position into the first stowed position during an unlocking movement. As a result, on the one hand the ease of use for the passenger seat can be further increased and further the operating reliability can be increased by a simple, safe and controlled movement for the transfer of the storage space from the second storage position. In addition, a vehicle seat is proposed with a backrest and a table device according to one of the previously described embodiments. Furthermore, if a lower side of the edge area of the storage surface of the table device at least in the second, locked stowed position in one direction of travel forms an overlap with a back surface of the backrest, in a suitable embodiment, a gap between the bottom of the edge region of the shelf and the back surface the backrest can be reduced, whereby the safety of the passenger increases and also a visually appealing, smooth appearance of a rear side of the vehicle seat can be achieved.

Description of the embodiments

FIG. 1 shows, in a schematic illustration, vehicle seats designed as passenger seats 12 with table devices according to the prior art in an installed state in an interior 10 of a vehicle designed as an aircraft. On a floor 11 of the interior 10 vehicle seats designed as passenger seats 12 are arranged in a known manner as a seat group next to each other and elevated in several rows of seats one behind the other. The passenger seats 12 each have a seating direction 13, which is parallel to an extension direction of the interior 10 of the aircraft and identical to a direction of flight.

Each passenger seat 12 is provided with a backrest 14 and a prior art table device provided for use by a passenger behind the passenger seat 12. Each of the table devices of the passenger seat 12 comprises a storage area 16 which is provided in a use position for depositing articles of daily use of the passenger, and a storage unit 20 which is provided to guide the storage area 16 during a movement between the use position and the storage position. For this purpose, the bearing unit 20 on each side on a pivot arm 21 which is pivotally mounted at an upper end with a first bearing means 22 at a front in the use position range of a side edge 17 of the shelf 16 about a first bearing axis 23 which is parallel to a in the use position in the seat direction 13 seen front edge 18 of the shelf 16 is arranged. At a lower end of each of the pivot arms 21 is pivotally mounted with a second bearing means 24 at a lower end of the backrest 14 of the passenger seat 12 about a second bearing axis 25 which extends transversely to the seating direction 13 and parallel to the first bearing axis 23. To adjust the position of use, the table device by a first pivotal movement of the bearing unit 20 about the second bearing axis 25 to the passenger located behind the passenger seat 12 pivotally out, and the storage area 16 is by a second pivoting movement into the position of use, in which the storage area 16 in We - Essentially aligned parallel to the bottom 11 of the interior 10 of the aircraft, can be brought. In the use position, the storage area 16 can also be drawn on two table guides, not shown in a known manner opposite to the seat 13 in the direction of the passenger in order to achieve an optimal position of the storage space 16 for the passenger.

To set the stowage position, the table device by a third pivotal movement of the bearing unit 20 about the second bearing axis 25 to the backrest 14 is pivoted out, and the shelf 16 can be moved by a fourth pivotal movement about the first bearing axis 23 in the stowed position in which the shelf 16 in Essentially aligned perpendicular to the bottom 11 of the interior 10 of the aircraft and is at least partially in contact with a rear surface 15 of the backrest 14. Above the storage area 16, the backrest 14 of the passenger seat 12 is equipped with a locking unit 26, which comprises a rotatably mounted knob 27. In the stowed position of the storage area 16, the toggle 27 can be brought into a position in which a partial overlap between the storage area 16 and the toggle 27 is established to secure the storage area 16 in the seat direction 13. The table devices of Fig. 1 are shown with the shelves 16 in the stowed position. Above the toggle 27, the passenger seat 12 is equipped on the rear surface 15 of the backrest 14 in the headrest area with a screen 29 of an IFE system. A size of the screen 29 is also limited by an arrangement of the toggle 27 and by a receptacle for holding the toggle 27 arranged concealed within the backrest 14.

In Figures 2a-2d, 3 and 4, several variants of the invention or of parts of the invention are shown. Each variant contains characteristics whose function is identical or fundamentally identical. These features are provided with reference numerals consisting of the figure number and the number of the feature common to all variants and thus form a single number.

FIG. 2 a shows a schematic representation of a section of a table device according to the invention of a vehicle seat designed as a passenger seat 230. This passenger seat 230 can the passenger seats 12 according to FIG. 1 in all respects except those relating to the table device replace, which is why dispense with a representation of a total passenger seat 230 and a mutual arrangement of several passenger seats 230 with table devices according to the invention and the design of the table device in Explained below on a section of a single passenger seat 230. The vehicle seat according to FIG. 2a designed as a passenger seat 230 is equipped with a backrest 214 and with a table device which is provided for use by a passenger located behind the passenger seat 230. The vehicle seat can be used in other embodiments in principle in other means of transport, for example in a railway car or in a coach. Each of the table devices of passenger seat 230 comprises a trim surface 216 provided in a use position for storing passenger articles of utility, and a bearing unit 220 intended to receive the trim surface 216 in movement between the use position and a first stowed position to lead. The storage surface 216 is internally provided with a cavity 231 which serves to receive various mechanical elements which are not visible from the outside.

To guide the movement of the storage surface 216, the storage unit 220 has on both sides a respective pivoting arm 221, which at an upper end with a first storage means 222 pivotally on a seen in the position of use in seat direction 213 front portion of a side edge 217 of the shelf 216th is mounted about a first bearing axis 223, which is arranged parallel to a in the use position in the seat direction 213 seen front edge 218 of the shelf 216 and parallel to the bottom 211 of the interior 210 of the aircraft. Arranged parallel to the first bearing axis 223 the table device comprises a stiffening means 232 formed by a torsion tube and provided for stiffening the pivot arms 221. At a lower end, each pivot arm 221 is pivotally mounted with a second bearing means 224 at a lower end of the seat back 214 of the passenger seat 230 about a second bearing axis 225 which extends transversely to the seating direction 213 and parallel to the first bearing axis 223.

To set the position of use, the table device is pivotable by a first pivoting movement of the bearing unit 220 about the second bearing axis 225 to the passenger located behind the passenger seat 230 back. Fig. 2a shows the table device in a middle position of the first pivoting movement. The storage area 216 can be brought into the use position by a second pivoting movement about the first bearing axis 223, in which the storage area 216 is aligned substantially parallel to the floor 211 of the interior 210 of the aircraft. In the use position, the storage surface 216 can moreover be pulled against the seating direction 213 in the direction of the passenger on two table guides 228 running in the seat direction 213 in order to achieve a position of the storage surface 216 which is optimal for the passenger.

To adjust the stowed position, the table device is pivotable about the second bearing axis 225 to the backrest 214 by a third pivoting movement of the bearing unit 220, and the storage surface 216 can be moved by a fourth pivoting movement about the first bearing axis 223 in the first stowed position in which the Parking area 216 is aligned substantially perpendicular to the bottom 211 of the interior 210 of the aircraft and is in partial contact with a rear surface 215 of the back rest 214. This position of the table device is shown in Fig. 2b.

The table device is equipped with a locking unit 233, which is provided to use a substantially parallel to the shelf 216 extending movement of the shelf 216 upwards as a locking movement. For this purpose, the locking unit 233 has a lifting unit 234 for lifting the storage surface 216 by the movement of the storage surface 216 substantially parallel to the storage surface 216 from the first storage position to a second, locked storage position. The function of the lifting unit 234 will be explained below. The lifting unit 234 comprises a rotary knob 235 which is rotatably mounted on a lower side 236 of the abutting surface 216 facing the bottom 211 of the inner space 210 in the use position of the abutting surface 216 in a central position about a rotational axis 37 within a predetermined rotational range. The knob 235 may be equipped for reasons of ease with a reduction. Such mechanisms are familiar to those skilled in the art, which is why it will not be discussed in detail here. Eccentrically mounted in the axis of rotation 37 of the knob 235 and rotatably coupled to the knob 235 is a rigid, rod-shaped support body 38 of the lifting unit 234, which protrudes with a support end 40 below the knob 235 and for raising the Absteilfläche 216 from the first stowed position in the second, locked stowed position is provided. At the support end 40, the support body 38 is provided with a first latching means 41 of the locking unit 233 formed by a molded-round notch. In the first stowed position, the rotary knob 235 is in an initial position, in which the support end 40 of the non-rotatably coupled support body 38 is located above the stiffening means 232 designed as a torsion tube. Should this not be the case due to an unintentional adjustment of the rotary knob 235, the position of the rotary knob 235 can be corrected by the passenger in a corresponding manner in order to achieve the first stowed position of the shelf 216. The torsion tube has, in a central position, a second latching means 42 of the locking unit 233 formed by an integrally formed cam. By rotation of the knob 235 from the initial position of the rotatably coupled support body 38 comes against the cam of the torsion tube in abutment, whereby a further movement of the knob 235 counteracts a force exerted by the shelf 216 weight. By overcoming this, the storage surface 216 is moved out of the first storage position and, guided by the table guides 228, upwards into the second storage position (FIG. 2c). In this case, the stiffening means 232 formed as a torsion tube forms a second supporting body 39 of the lifting unit 234, on which the first, rigid, rod-shaped supporting body 38 is supported. With sufficient rotation of the knob 235, in which continuously the weight of the shelf 216 and possibly existing frictional forces of the table guides 228 must be overcome, form the round notch of the support body 38 formed locking means 41 and integrally formed as a cam of the torsion formed latching means 42 a positive connection 45, with the The footprint 216 is again slightly lowered from a highest position to form the interlocking connection 45 (FIG. 2c). By the positive connection 45 of the locking means 41, 42 of the locking unit 233, the shelf 216 is held in the second, locked stowed position in a fixed position, since a movement of the shelf 216 from the second, locked stowed position only by overcoming the weight of the shelf 216 is possible ,

The exemplary embodiment described here includes a rotary knob 235 for moving the first rigid support body 38, with which the storage surface 216 can be moved from the first storage position into the second, locked storage position. In principle, in order to carry out the movement of the rigid support body 38 in place of a rotating device, other means familiar to the person skilled in the art may also be used, for example folding devices or sliding devices. Trained as passenger seat 230 vehicle seat has on the back surface 215 of the backrest 214 integrally formed on the backrest 214 protrusion lip 43 and, in the sitting direction 213 to the supernatant lip 43 then, a contact surface 244 on. As a result of the movement of the storage surface 216 from the first storage position to the second, locked storage position, the storage surface 216 is pushed with a lower side 236 of an edge region 219 in the seat direction 213 in front of the projection lip 43 and with an end surface of the storage surface 216 against the contact surface 244 is applied so that the bottom 236 of the edge region 219 of the shelf 216 of the table device in the second, locked stowed position in the seating direction 213 forms an overlap with the rear surface 215 of the back 214. In the second, locked stowed position, the edge region 219 of the storage surface 216 further forms a corresponding partial element of a positive connection 246. The other corresponding partial element of the positive connection 246 is of a backrest 214 facing inside of the molded projection lip 43 and the contact surface 244 of the back surface 215 of Backrest 214 formed.

FIG. 3 shows a plurality of further embodiments of a region 319 close to the edge of depositing surfaces 316 of a table device according to FIGS. 2a-2d in a second, locked stowed position. 3, a front end face of the abutment surface 316 seen in the seated position 313 is provided with a chamfer 47 forming a first corresponding subelement of a positive connection 346. A second subelement of the interlocking connection 346 forms one of the chamfer 47 corresponding undercut 48 which is integrally formed on the back surface 315 of the backrest 314. In the seat direction 313, the underside 336 of the edge region 319 of the abutment surface 316 in the second locked stowed position forms an overlap with the back surface 315 of the backrest 314 Embodiment "B" of Fig. 3 is seen in the use position in the seat direction 313 front end face of the Absteilfläche 316 equipped with this perpendicular to this end edge 49, the bil a first corresponding sub-element of a positive connection 346 det. A second sub-element of the interlocking connection 346 is provided by a panel 50 attached to the rear surface 315 of the backrest 314 and a bearing surface 344 forming part of the back surface 315 of the backrest 314. In the seat direction 313, the underside 336 of the edge region 319 of the abutment surface 316 in the second, locked stowed position forms an overlap with the aperture 50 attached to the rear surface 315 of the backrest 314.

In embodiment "C" of Fig. 3, a front end surface of the shelf 316 seen in the seated position 313 is provided with a tapered edge land 51 forming a first corresponding sub-element of a positive joint 346. A second sub-element of the interlocking joint 346 is formed by a groove 52, which is formed in the rear surface 315 of the seat back 314. In the second locked storage position, the edge web 51 engages the groove 52 and, viewed in the seat direction 313, overlaps the back surface 315 of the seat back 314. An alternative Exemplary embodiment of a locking unit 433 of the table device on the vehicle seat designed as passenger seat 430 according to FIGS. 2a-2d is shown in FIG. The locking unit 433 also has a lifting unit 434 for lifting the Abstelifläche 416 by the running substantially parallel to the Abstelifläche 416 movement of the Abstelifläche 416 from the first stowed position in the second, locked stowed position. In contrast to the locking unit 233 according to the exemplary embodiment of FIGS. 2a-2d, the locking unit 433 comprises a lowering means 53, which is designed as a plastic band and is intended to be used in a

Unlocking the Abstelifläche 416 from the second, locked stowed position in the first stowed position lower. The lifting unit 434 comprises two flexible bands designed as plastic bands

Pulling means 54, 55, which are fixed in the cavity 431 in the interior of the Abstelifläche 416, each with one end 56, 57 on each one of the two table guides 428. The two ends 56, 57 of each of the two plastic straps are, when viewed in the first storage position of the Abstelifläche 416, fixed at the same height, and attached to the same table guide 428 ends 56, 56 'and 57, 57' of the two plastic bands are in height spaced. By an extension of the one of the two plastic straps the Abstelifläche 416 by the running substantially parallel to the Abstelifläche 416 movement of the Abstelifläche 416 from the first stowed position in the second, locked stowed position available and by stretching the other of the two plastic tapes is the Abstelifläche 416 the substantially parallel to the Abstelifläche 416 extending

Movement of the Abstelifläche 416 from the second, locked stowed position in the first stowage position can be brought, as will be explained below.

The lifting unit 434 further comprises a rotary knob 435 rotatably mounted about an axis of rotation 58 in the sloped surface 416 and a support body 59 having an elliptical shaped cross-section which is non-rotatably connected to the rotary knob 435 eccentrically to the axis of rotation 58. In a use position of the Abstelifläche 416, the knob 435 is in a rotational position in which a main axis 60 of the elliptical shaped cross section of the support body 59 is arranged transversely to the sitting direction 413 and parallel to the bottom 411 of the interior 410 of the aircraft. The lowering means 53, which is formed in the first stowage position of the Abstelifläche 416 of the higher arranged of the two plastic bands, in the use position of the Abstelifläche 416 partially in loose engagement with an upper peripheral side 61 of the elliptically shaped cross-section of the support body 59th Das in der Stowage position of the Abstelifläche 416 deeper arranged of the two Plastic bands is in the use position of the Absteilfläche 416 partially in loose contact with a lower peripheral side 62 of the elliptically shaped cross section of the support body 59. Upon rotation of the knob 435 in the clockwise direction from the existing in the use position of Absteilfläche 416 rotational position leads to a driving movement of the support body 59 an extension of the lower-lying plastic tape until the plastic strip between the respective fixed ends 56 ', 57' and a beginning of a contact surface 63 of the plastic strip on the support body 59 is rectilinear. The support body 59 is supported and thus the Absteilfläche 416 upon further rotation of the knob 435 in a clockwise direction, wherein the rotation counteracts a force exerted by the Absteilfläche 416 weight force on the lower plastic belt from, whereby the Absteilfläche 416 from the first stowage position and, by guided the table guides 428, can be brought up in the second storage position. The length of the higher plastic band is designed so that the higher arranged

Plastic tape in the second storage position of the shelf 416 rests on the support body 59 by the action of gravity and with a slight further movement of the support body 59 upwards to the plant to the support body 59 and reached a state of extension. 4, the locking device in the second stowed position of the storage surface 416 is shown with a dashed line.

Upon rotation of the knob 435 counterclockwise from the existing in the second storage position of the shelf 416 rotational position, the entrainment movement of the support body 59 leads to an extension of the higher plastic belt, since a distance from the contact surface of the plastic tape to the support body 59 to the axis of rotation 58 of the knob 435 increased by the rotation. As a result, the storage surface 416 can be brought from the second storage position into the first storage position in a controlled manner. The movement of the shelf 416 through the

Lifting unit 434 from the second stowed position to the first stowed position is for the most part independent of an effect of gravity. An undesired prevention of the movement of the storage surface 416 from the second storage position to the first storage position by a static friction between the storage surface 416 and the protrusion lip 443 and the abutment surface 444 of the back surface 415 of the backrest 414 is advantageously avoided by the lowering means 53. To secure the storage surface 416 in the second, locked stowed position, the locking unit 433 on securing means. The knob 435 is provided with a cylindrical recess in which a first securing means formed by a push button 65 is held movable in a direction perpendicular to the shelf 416 and secured in a known manner by a retaining ring (not shown) against falling out. On a side facing the cavity 431 of the shelf 416 side, the push button 65 forms a cylindrical cavity which is provided for receiving a second securing means formed by a spring-loaded, cylindrical pin 64. The spring-loaded, cylindrical pin 64 is positioned in the cavity 431 of the storage surface 416 at a position that is in the second stowed position of the storage surface 416 in the seat direction 413 seen in the seat 413 in register with the push button 65, so that the spring-loaded, cylindrical pin 64 after a shipment of the Abstellfläche 416 enters the second stowed position in the cylindrical cavity of the push button 65 and locks a rotation of the knob 435 counterclockwise, so that the Abstell- surface 416 is secured in the second stowed position against further movement, the after pressing the push button 65 and simultaneously turning the knob 435 can take place counterclockwise.
