Description

[0001] The invention relates to a vehicle occupant protection device comprising a folding table assigned to a vehicle seat and positionable between a use position and a stowed position, and an airbag assembly integrated therein. Furthermore, the invention relates to a vehicle having such an occupant protection device.

[0002] DE 10 2021 003 331 A1 discloses an occupant protection device for a vehicle, a vehicle with at least one occupant protection device, and a method for operating an occupant protection device. The occupant protection device comprises a table assigned to a vehicle seat. Upon detection of a collision and / or a risk of collision of the vehicle, the table can be actively moved into an occupant protection position, in which it supports a portion of the occupant's body against collision-related displacement or forms a support surface for an airbag deploying from another vehicle part.

[0003] Furthermore, DE 10 2021 111 034 A1 describes a folding table device and a vehicle with a folding table device. The folding table device for a vehicle seat comprises a table top, an articulated arm, a joint, a gas bag, and a gas generator connected to the gas bag, by means of which the gas bag is inflatable. The table top can be adjusted via the joint with the articulated arm about a pivot axis from a rest position to a use position and from the use position to the rest position. Furthermore, the gas bag and the gas generator are attached to the table top. The distance of the center of gravity of the gas generator to the pivot axis is smaller than the distance of the center of gravity of the folded gas bag to the pivot axis.

[0004] Furthermore, US 11,091,110 B2 discloses an occupant protection device with a table arranged facing a seat back and an airbag arranged in the table. The airbag deploys between the table and the upper body of the occupant sitting in front of the airbag.

[0005] The invention is based on the object of providing a novel occupant protection device with a folding table and an airbag arrangement as well as a vehicle with such an occupant protection device.

[0006] The object is achieved according to the invention by an occupant protection device which has the features specified in claim 1 and by a vehicle which has the features specified in claim 10.

[0007] Advantageous embodiments of the invention are the subject of the subclaims.

[0008] An occupant protection device for a vehicle comprises a folding table assigned to a vehicle seat and positionable between a use position and a stowed position, and an airbag arrangement integrated therein. According to the invention, the airbag arrangement comprises an airbag integrated into the folding table, which assumes its operative position upon detection of an imminent collision with the vehicle or upon detection of a collision of the vehicle in the use position and / or in the stowed position. To assume its operative position, a first part of the airbag deploys from a first surface side of the folding table, at least in sections in front of an upper body and / or in the direction of the upper body of an occupant sitting on the vehicle seat.A second part of the airbag unfolds from a second surface side of the folding table in the direction of the legs of the occupant on the vehicle seat to assume its operational position and / or supports the positioning of the first part of the airbag in the direction of the occupant on the vehicle seat through its operational position.

[0009] By means of an occupant protection device designed in this way, occupant protection for a vehicle seat occupant can be increased, as the respective part of the airbag assumes its active position relative to the occupant, thereby significantly reducing the risk of collision-related injury to the occupant. Furthermore, by means of the second part of the airbag, when it deploys in the use position of the folding table, the risk of the occupant slipping under a lap belt when a seat belt is fastened and the vehicle is involved in a frontal collision is significantly reduced. By means of the second part of the airbag positioned in its active position, the occupant is at least partially secured in relation to their seating position on the vehicle seat.

[0010] In one embodiment, the airbag, with its first part and its second part, is integrated into a support element of the folding table that has both surface sides. The airbag is integrated into the support element in such a way that a respective deployment direction for assuming the respective active position of the two parts of the airbag is predetermined, both when the folding table is in the use position and the stowed position. In particular, the support element has a horizontal position in the use position, so that the first part of the airbag deploys from the first surface side towards a vehicle roof and the first part of the airbag deploys towards the occupant when the folding table is in the stowed position. In particular, the two parts of the airbag deploy regardless of whether the folding table is in the use position or the stowed position, thereby reducing the risk of injury to the occupant.

[0011] In a further embodiment, the two surfaces of the support element from which the respective airbag deploys are arranged opposite each other. This allows the first part of the airbag to deploy in front of the occupant's upper body when the folding table is in use, counteracting a collision-induced forward displacement of the occupant, while the second part of the airbag is positioned toward the occupant's legs when the folding table is in use, preventing the so-called submarining effect.

[0012] In one possible embodiment, the surface sides each have an airbag outlet opening closed by an airbag cover, which is released in the event of a collision, so that the respective airbag can assume its respective effective position to increase injury protection for the occupant.

[0013] In one embodiment of the occupant protection device, the respective airbag cover is coupled to a controllable opening mechanism. This means that the airbag cover opens when the opening mechanism is activated, whereby the airbag cover's pivoting movement can be assisted by the respective airbag deploying.

[0014] In one embodiment, an opening mechanism on the first surface side is diagonally opposite another opening mechanism on the second surface side, so that a first airbag cover pivots open in one direction and a second airbag cover pivots open in an opposite direction, and the respective parts of the airbag unfold from the respective airbag outlet opening and assume their operative position. For example, a deployment direction of the respective part of the airbag can be specified by means of the respective opened airbag cover.

[0015] In a further embodiment, a predetermined breaking point and / or tear seam is or is introduced into the respective surface side to release the respective airbag outlet opening, at least in part surrounding said airbag. Upon deployment of the respective part of the airbag, the predetermined breaking point breaks or the tear seam tears open, allowing the respective part of the airbag to fully deploy and assume its operational position in order to limit the collision-related forward displacement of the occupant, to support the positioning of the airbag, or to reduce the risk of submarining.

[0016] In one embodiment of the occupant protection device, the support element is held between two parallel support struts, which are arranged to be partially displaceable along these struts and / or pivotable about at least one pivot axis. The two support struts are arranged laterally, opposite one another, on the support element, so that, particularly when the folding table is in its use position, a free space for the occupant's legs and feet is formed between the two support struts. The two support struts are spaced apart from one another in such a way that the free space is sufficiently large to allow the occupant to sit comfortably and, if necessary, to change their leg positions.

[0017] In one embodiment, the support element has a user interface on the first surface side, which is designed, for example, as a touch-sensitive input unit, in particular a keyboard and / or display unit. For example, the user interface can be a tablet PC that can be arranged in the support element or is integrated into the support element. When the folding table is in the stowed position, the occupant can, for example, watch a film using the touch-sensitive display unit, whereas when the folding table is in use, the touch-sensitive display unit can be used as an input unit, for example for creating a presentation. The user interface can also be used for video telephony, provided it is designed accordingly.

[0018] Furthermore, the invention relates to a vehicle with an occupant protection device which has a folding table with an integrated airbag and which occupant protection device is assigned to an occupant on a vehicle seat, in particular a second row of seats. In this case, a first part of the airbag unfolds from a first surface side of the folding table at least partially in front of an upper body and / or in the direction of the upper body of an occupant sitting on the vehicle seat to assume its active position. A second part of the airbag unfolds from a second surface side of the folding table in the direction of the legs of the occupant sitting on the vehicle seat to assume its active position and / or supports, through its active position, a positioning of the first part of the airbag in the direction of the occupant on the vehicle seat.

[0019] Embodiments of the invention are explained in more detail below with reference to drawings.

[0021] Corresponding parts are provided with the same reference numerals in all figures.

[0022] Fig. 1 shows, by way of example and in a highly simplified manner, a sectional view of a vehicle 1 with an occupant 2 on a vehicle seat 3 in the rear area of ​​the vehicle 1, a first part 5.1 of an airbag 5 and a second part 5.2 of the airbag 5 of an occupant protection device 1 in their respective active positions and a further vehicle seat 6, for example a driver's seat of the vehicle 1.

[0023] The airbag 5 has two parts, 5.1 and 5.2. The first part, 5.1, of the airbag has a larger volume in its deployed or inflated active position than the second part, 5.2, of the airbag 5 in its deployed or inflated active position.

[0024] In general, it is known that increasing requirements with regard to vehicle safety as well as a desire for more comfortable driving and / or more comfortable automated driving of vehicles 1, an improvement of occupant protection devices I and a simultaneous increase in the adaptation of the occupant protection devices I, for example due to a changed seating position of the occupants 2, are required.

[0025] In particular, it is intended to provide an occupant 2 in a second row of seats of the vehicle 1, as in Fig. 1, to enable working relatively conveniently, for example by means of a laptop and / or another input unit, in particular, while driving the vehicle 1.

[0026] For this purpose, the occupant protection device I is provided, which has a folding table 7 and the airbag 5 with its first part 5.1 and its second part 5.2.

[0027] According to Fig. 1, the folding table 7 is positioned in its use position, in which the folding table 7 is unfolded and a support element 7.1 is positioned horizontally and can serve as a work surface for the occupant 2.

[0028] The airbag 5, with its two parts 5.1 and 5.2, is integrated into the support element 7.1 of the folding table 7 in its initial position, i.e. during normal operation of the vehicle 1, and is not visible. Integrated into the support element 7.1, in particular into a first surface side 7.2 facing the occupant 2, is a Fig. 9, from which the airbag 4 deploys to assume its operational position. In the use position of the folding table 7, the first surface side 7.2 faces a vehicle roof 1.1.

[0029] A second surface side 7.3 opposite the first surface side 7.2 also has a second airbag exit opening 9.1, from which the second part 5.2 of the airbag 5 deploys to assume its operational position. The second surface side 7.3 is arranged in the use position of the folding table 7 and thus in the horizontal position of the support element 7.1 in the direction of the legs 2.1 of the occupant 2.

[0030] The airbag outlet openings 8.1 and 9.1 are in the initial position of the airbag 5, i.e. in the non-deployed state, by means of a Fig. 4 to 9, for example by means of a so-called respective airbag flap.

[0031] In order to ensure as far as possible that the airbag covers 8, 9 open in the event of a detected imminent collision with the vehicle 1 or in the event of a detected collision of the vehicle 1, a predetermined breaking point and / or a tear seam is introduced into the respective surface side 7.2 and 7.3 of the support element 7.1, for example, circumferentially in sections around the respective airbag cover 8, 9. In particular, a tear seam is selected if the respective airbag cover 8, 9 is connected to the support element 7.1, for example, by means of a flexible and / or textile-like material.

[0032] In one embodiment, the airbag covers 8, 9 are connected to the support element 7.1 by means of at least one retaining strap (not shown in detail), so that the airbag covers 8, 9, in particular when the respective airbag outlet opening 8.1 and 9.1 is released, are nevertheless fixed to the support element 7.1 and do not fly around in the vehicle 1 and represent an additional risk of injury for the occupant 2 and / or other occupants.

[0033] In one embodiment, the support element 7.1 has a user interface, for example, an input unit in the form of a keyboard and / or a touch-sensitive display unit, for example, in the form of a tablet PC. For example, the tablet is integrated as a display unit or other input unit into the first surface side 7.2 of the support element 7.1, which, in the use position of the folding table 7, faces the vehicle roof 1.1. Such a flat user interface can also form the airbag cover 8 of this surface side.

[0034] Furthermore, the support element 7.1 is pivotally arranged between two parallel support struts 7.4, so that the support element 7.1 can assume its horizontal position in the use position of the folding table 7. A pivot axis S1 runs parallel to a vehicle transverse axis. For example, the support element 7.1 and / or the support struts 7.4 have or have at least one fixing element for fixing the support element 7.1 to the support struts 7.4 both in the use position and in a Fig. 3 shown storage position.

[0035] The two support struts 7.4 are pivotally attached at one end to a seat back of the additional vehicle seat 6 or to a vehicle floor 1.2. The pivoting range of the support struts 7.4 is limited, for example, by at least one stop element (not shown in detail). For example, the pivoting range can be adjusted to adjust the inclination of the support struts 7.4 and thus the position of the support element 7.1 relative to the occupant 2, for example, depending on their body size. A further pivot axis S2, about which the support struts 7.2 of the folding table 7 can pivot, runs essentially parallel to the pivot axis S1.

[0036] Fig. Figure 3 shows a side view of the two parts 5.1 and 5.2 of the airbag 5 in the deployed state, with both parts 5.1 and 5.2 of the airbag 5 being fluidically coupled to a gas generator 10. If only one gas generator 10 is provided, the first part 5.1 and the second part 5.2 of the airbag 5 are pressurized with a gas, in particular air, essentially simultaneously and then assume their operative position. The gas generator 10 is accommodated in the support element 7.1.

[0037] In one embodiment, the two parts 5.1 and 5.2 of the airbag 5 can have controllable valves, making it possible to supply only one of the two parts 5.1 and 5.2 of the airbag 5 with gas from the gas generator 10, so that only one of these two parts 5.1 and 5.2 of the airbag 5 assumes its active position. Furthermore, by controlling the valves, it is possible to ensure that both parts 5.1 and 5.2 of the airbag 5 are supplied with gas simultaneously or at different times.

[0038] In Fig. 4 shows two figures A1, A2, wherein the folding table 7 is shown in the stowed position in a first figure A1 and the folding table 7 is shown in its active position by means of a dashed line. In Fig. 4 For reasons of clarity, only the first part 5.1 of the airbag is shown in dashed lines in Figures A1 and A2.

[0039] A second figure A2 shows a sequence of positioning the folding table 7 from the storage position to the use position.

[0040] In the stowed position, the support element 7.1 is essentially not visible in a side view of the folding table 7, since the support element 7.1 is arranged completely between the two support struts 7.4.

[0041] The first surface side 7.2 of the support element 7.1 is positioned toward the occupant 2 on his or her vehicle seat 3, so that the first part 5.1 of the airbag 5 deploys, if necessary, toward the occupant 2, in particular toward the upper body of the occupant 2. The second surface side 7.3 of the support element 7.1 is positioned toward the other vehicle seat 6.

[0042] In the stowed position, the folding table 7 lies essentially over its entire surface against a rear side of a seat back 6.1 of the further vehicle seat or is arranged at least in sections within the seat back 6.1, whereby the occupant 2 still has sufficient free space, in particular with regard to his legs and to the seat back 6.1.

[0043] In the active position of the airbag 5 and when the occupant 2 impacts the airbag 5, the latter is supported in particular by means of the seat back 6.1 of the further vehicle seat 6 and is thus stabilized in its active position.

[0044] To position the folding table 7 from the stowed position to the use position, the support element 7.1 can first be pivoted manually, electrically, pneumatically, and / or hydraulically about the second pivot axis S2 in the direction of the occupant 2. The folding table 7 is then pivoted toward the occupant 2 by means of the pivotably mounted support struts 7.4, for example, until a comfortable position for the occupant 2 is reached. The pivoting of the folding table 7 can also be performed manually, electrically, pneumatically, and / or hydraulically. Further pivoting movement of the folding table 7 is limited by the at least one stop element, wherein the inclination of the folding table 7 can be adjusted, for example, by appropriately positioning the stop element. The support element 7.1 is then pivoted manually, electrically, pneumatically, and / or hydraulically about the first pivot axis S1 into the horizontal position.

[0045] Fig. 5 shows, based on figures A1 to A5 of the occupant protection device I, a sequence for positioning the folding table 7 from the stowed position to the use position in an alternative embodiment of the folding table 7. Also in the Fig. 5 For reasons of clarity, only the first part 5.1 of the airbag is shown in dashed lines in Figures A1 to A5.

[0046] In a first figure A1 of the Fig. 4, the folding table 7 is shown in a stowed position, with the support element 7.1 partially projecting beyond the support struts 7.4 in the direction of the vehicle roof 1.1. For example, the support element 7.1 is arranged at the height of a headrest of the additional vehicle seat 6. The occupant 2 can thus relatively comfortably direct his gaze towards the user interface, for example, a touch-sensitive display unit and / or another input unit, which is arranged on the support element 7.1.

[0047] To assume the use position of the folding table 7, the support element 7.1 is pushed between the support struts 7.4 in the direction of the vehicle floor 1.2, for example by means of guide rails not shown in detail, as shown in a second figure A2.

[0048] The support element 7.1 can then be pivoted from bottom to top into an intermediate position shown by a dashed line via the first pivot axis S1, which is moved with the support element 7.1, as shown in a third figure A3.

[0049] Even in the intermediate position, the first surface side 7.2 with the first airbag outlet opening 8.1 is positioned in the direction of the vehicle roof 1.1, so that the airbag 5 can unfold upwards between the further vehicle seat 6 and the occupant 2.

[0050] From this intermediate position, the support element 7.1 can be moved upwards between the support struts 7.4, i.e. in the direction of the vehicle roof 1.1, as shown in the fourth figure A4.

[0051] The folding table 7 is then pivoted about the second pivot axis S2 in the direction of the occupant 2 and the support element 7.1 into its horizontal position, as shown in a fifth figure A5.

[0052] All exemplary embodiments have in common that, in order to assume its active position in the event of a detected imminent collision with the vehicle 1 or in the event of a detected collision of the vehicle 1, the airbag 5, both in the use position and in the stowed position of the folding table 7, unfolds with its first part 5.1 from the first surface side 7.2 of the support element 7.1 of the folding table 7 at least partially in front of an upper body and / or in the direction of the upper body of an occupant 2 located on the vehicle seat 3. The second part 5.2 of the airbag 5 unfolds in the use position from the second surface side 7.3 of the support element 7.1 of the folding table 7 in the direction of the legs 2.1 of the occupant 2 and in the stowed position in the direction of the seat back 6.1 of the other vehicle seat 6.

[0053] In particular, in the use position of the folding table 7 and the support element 7.1 thus arranged in the horizontal position, the airbag 5 thus deploys from its first airbag outlet opening 8.1 of the first surface side 7.2 and assumes its active position. In the active position, the first part 5.1 of the airbag 5 extends in front of the upper body of the occupant 2, so that the occupant 2 is displaced forward due to a collision-induced acceleration acting on him and impacts the first part 5.1 of the airbag 5. The forward displacement path of the occupant 2 is limited by the airbag 5, so that it can be largely ruled out that the occupant 2's head will impact the other vehicle seat 6.

[0054] Additionally, the second part 5.2 of the airbag 5 of the occupant protection device I deploys from the second surface side 7.2 toward the legs 2.1, particularly the thighs, of the occupant 2. In the event of a frontal collision of the vehicle 1, the second part 5.2 of the airbag 5, which is in its active position, can significantly reduce the risk of the occupant 2 slipping under a lap belt of his fastened seat belt. In particular, the occupant 2 is secured in his seated position by the second part 5.2 of the airbag 5.

[0055] Fig. 2 shows the occupant and the folding table 7, which is in its stowed position, with the two parts 5.1 and 5.2 of the airbag 5 deployed. In the stowed position of the folding table 7, it rests essentially flat against the seat back 6.1 of the additional vehicle seat 6. The first surface side 7.2 faces the occupant 2, and the opposite second surface side 7.3 rests against the additional vehicle seat 6. If it is detected that the vehicle 1 is about to collide, or if the collision itself is detected, and the folding table 7 is in its stowed position, the two parts 5.1 and 5.2 of the airbag 5 are nevertheless deployed and deployed.

[0056] The first part 5.1 of the airbag 5 deploys from the first surface side 7.2 of the support element 7.1 facing the occupant 2 in the direction of the occupant 2, thereby limiting the forward displacement path of the occupant 2. The second part 5.2 of the airbag 5 deploys from the surface side of the support element 7.1 facing the other vehicle seat 6, so that the second part 5.2 of the airbag 5 is arranged between the seat back 6.1 and the folding table 7, in particular the support element 7.1. The second part 5.2 of the airbag 5 supports the positioning of the first part 5.1 of the airbag 5 relative to the occupant 2, since the second part 5.2 of the airbag 5, in this active position, positions the folding table 7, in particular the support element 7.1 and the first part 5.1 of the airbag 5, toward the occupant 2. In particular, the folding table 7 pivots due to the deployment of the second part 5.2 of the airbag 5 by a predetermined pivoting range in the direction of the occupant 2, whereby the forward displacement path of the occupant 2 is further limited. The first part 5.1 of the airbag 5 is supported on the support element 7.1, which is supported on the second part 5.2 of the airbag 5, which in turn is supported on the seat back 6.1 of the further vehicle seat 6. Thus, a force conversion and force transmission to the seat back 6.1 of the further vehicle seat 6 takes place. The second part 5.1 of the airbag 5 facing the occupant 2 is relatively stationary in this active position, whereby injury protection for the occupant 2 can be increased.

[0057] Preferably, both parts 5.1 and 5.2 of the airbag 5 are activated separately from each other in the use position and in the stowed position, and activated as needed. For example, it is conceivable that if the seat back 6.1 of the additional vehicle seat 6 is positioned lower, toward the occupant 2, the second part 5.2 of the airbag 5 will not be deployed. It is also conceivable to dispense with the second part of the airbag 5.2.

[0058] The Fig. 7 to 9 each show a sectional view of the support element 7.1 of the folding table 7 with the two airbag covers 8, 9 and a controllable opening mechanism O1, O2, wherein one opening mechanism O1 is assigned to the airbag cover 8 and a further opening mechanism O2 is assigned to the further airbag cover 9.

[0059] The opening mechanism O1 is located diagonally opposite the further opening mechanism O2, so that the airbag covers 8, 9 open in opposite directions. For example, the respective opening of the airbag cover 8, 9 can be used to specify a deployment direction for the respective part 5.1 and 5.2 of the airbag 5.

[0060] Fig. 6 shows the support element 7.1 with closed airbag covers 8, 9 and still closed opening mechanism O1, which is currently being opened and closed opening mechanism O2. Fig. 7 shows the support element 7.1 with the airbag covers 8, 9 still closed and the opening mechanisms O1, O2 closed. Fig. Figure 8 shows the support element 7.1 with closed airbag covers 8, 9 and the opened opening mechanism O1, wherein the further opening mechanism O2, which is associated with the second part 5.2 of the airbag 5, is closed. Fig. 8 the airbag cover 8 is open and the first part 5.1 of the airbag 5 is shown in its active position.

[0061] The respective opening mechanism O1, O2 comprises a controllable hook element 11, which is pivotably arranged within the support element 7.1. For example, the respective hook element 11 is coupled to a collision sensor system of the vehicle 1, so that the respective hook element 11 is controlled and executes a pivoting movement when a collision is detected that is imminent with the vehicle 1 or when a collision of the vehicle 1 is detected.

[0062] In the closed state of the opening mechanisms O1, O2, the respective hook 11 engages, for example, in an eyelet and / or is held in another way, so that the respective airbag cover 8, 9 does not open unintentionally, in particular when positioning the support element 7.1.

[0063] If the hook 11 is released due to the activation, the airbag cover 8 pivots open by unfolding the first part 5.1 of the airbag 5 and takes up its active position, as shown in Figure A5 of the Fig. 5 is shown.
