Abstract
Description
[0001] The invention relates to an occupant protection device for a vehicle comprising a folding table assigned to a vehicle seat and positionable between a usable position and a stowed position, and an airbag arrangement integrated therein. The invention further relates to a vehicle with such an occupant protection device.
[0002] German patent application 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 associated with a vehicle seat. Upon detection of a collision and / or risk of collision, the table can be actively moved into an occupant protection position in which it supports a body part of an occupant against collision-induced displacement or forms a support surface for an airbag deploying from another part of the vehicle.
[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 tabletop, an articulated arm, a joint, a gas bag, and a gas generator connected to the gas bag, by means of which the gas bag can be inflated. The tabletop can be adjusted via the joint with the articulated arm about a pivot axis from a rest position to a working position and from the working position to the rest position. The gas bag and the gas generator are also attached to the tabletop. The distance of the gas generator's center of gravity to the pivot axis is less than the distance of the folded gas bag's center of gravity to the pivot axis.
[0004] Furthermore, US patent 11,091,110 B2 discloses an occupant protection device comprising a table facing a seat back and an airbag integrated into the table. The airbag deploys between the table and the upper body of the occupant sitting in front of the airbag.
[0005] DE 10 2017 128 097 A1, DE 10 2021 122 110 A1, and WO 2023 / 036 784 A1 each disclose, individually, an occupant protection device for a vehicle with a folding table assigned to a vehicle seat and positionable between a usable position and a stowed position, and an airbag assembly integrated therein. The airbag assembly comprises a first part and a second part of an airbag integrated into the folding table, which assume their respective deployment positions upon detection of an impending collision or upon detection of a collision of the vehicle in the usable position. To assume its deployment position, the first part of the airbag deploys from a first surface of the folding table, at least partially in front of and / or towards the upper body of an occupant located in the vehicle seat.The second part of the airbag unfolds from a second surface of the folding table towards the legs of the occupant on the vehicle seat to assume its operational position and / or supports, through its operational position, a positioning of the first part of the airbag towards the occupant on the vehicle seat.
[0006] The invention is based on the objective of specifying a novel occupant protection device with a folding table and an airbag arrangement, as well as a vehicle with such an occupant protection device.
[0007] The problem is solved 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.
[0008] Advantageous embodiments of the invention are the subject of the dependent claims.
[0009] An occupant protection device for a vehicle comprises a folding table assigned to a vehicle seat and positionable between a usable position and a stowed position, an airbag assembly integrated therein, and a support element that is positioned horizontally in the usable position of the folding table and can serve as a work surface for the occupant. According to the invention, the airbag assembly comprises an airbag integrated into the folding table, which assumes its operational position in the event of a detected impending collision or a detected collision of the vehicle in the stowed position. In the stowed position, the folding table rests substantially against the back of a seatback of another vehicle seat over its entire surface or is at least partially arranged within the seatback.The first part of the airbag deploys from one surface of the folding table towards the upper body of an occupant in the vehicle seat. A second part of the airbag deploys from the other surface of the support element, facing the other side of the vehicle seat, thus positioning itself between the seat back and the folding table. This second part of the airbag, in turn, assists in positioning the first part of the airbag towards the occupant in the vehicle seat.
[0010] By means of such a designed occupant protection device, the protection of an occupant in the vehicle seat can be increased, as the respective part of the airbag assumes its deployment position relative to the occupant, thereby significantly reducing the risk of collision-related injury. Furthermore, when the second part of the airbag deploys in the usable position of the folding table, the risk of the occupant sliding under the lap belt in a frontal collision, while wearing a seat belt, is considerably reduced. With the second part of the airbag positioned in its deployment position, the occupant is at least partially restrained in their seating position in the vehicle seat.
[0011] In one embodiment, the airbag, with its first and second parts, is integrated into a support element of the folding table that has two surface sides. The airbag is integrated into the support element in such a way that a specific deployment direction is predetermined for the two parts of the airbag to assume their respective effective positions, regardless of whether the folding table is in its operating or stowed position. Specifically, in the operating position, the support element is horizontal, so that the first part of the airbag deploys from the first surface side towards the vehicle roof, and in the stowed position, the first part of the airbag deploys towards the occupant. In particular, both parts of the airbag deploy regardless of whether the folding table is in its operating or stowed position, thus reducing the risk of injury to the occupant.
[0012] In another embodiment, the two surface sides of the support element, from which the respective airbags deploy, are arranged opposite each other. Thus, in the usable position of the folding table, the first part of the airbag deploys in front of the occupant's upper body to counteract forward displacement of the occupant in a collision, while the second part of the airbag, in the usable position of the folding table, positions itself towards the occupant's legs to prevent the so-called submarining effect.
[0013] In one possible design, each surface has an airbag discharge opening closed by means of 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 protection against injury to the occupant.
[0014] The respective airbag cover is coupled to an actuated opening mechanism in one version of the occupant protection device. This means that the airbag cover opens when the opening mechanism is activated, and the deploying airbag can assist in the opening movement of the airbag cover.
[0015] In one embodiment, an opening mechanism on the first surface is diagonally opposite another opening mechanism on the second surface, so that a first airbag cover pivots in one direction and a second airbag cover in the opposite direction, and the respective parts of the airbag unfold from their respective airbag deployment openings and assume their operational position. For example, the deployment direction of each airbag part can be predetermined by the opening of each airbag cover.
[0016] In another embodiment, a predetermined breaking point and / or tear seam is incorporated into the respective surface side to release the airbag deployment opening, at least partially circumferencing it. When the respective part of the airbag deploys, the predetermined breaking point or tear seam opens, allowing the respective part of the airbag to fully deploy and assume its effective position to limit the forward displacement of the occupant in a collision, to support the positioning of the airbag, or to reduce the risk of submarining.
[0017] In one embodiment of the occupant protection device, the support element is held between two parallel support struts, and is arranged to be slid along these struts in sections and / or pivotable about at least one pivot axis. The two support struts are arranged laterally and opposite each other on the support element, so that, particularly in the use position of the folding table, a space is provided between the two support struts for the occupant's legs and feet. The two support struts are spaced apart from each other such that the space is sufficiently large to allow the occupant to sit comfortably and, if necessary, to change their leg position.
[0018] In one embodiment, the support element has a user interface on its first surface, which may be designed, for example, as a touch-sensitive input unit, particularly a keyboard and / or display unit. For instance, the user interface could be a tablet PC that can be positioned in or integrated into the support element. When the folding table is in its 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, to create a presentation. The user interface can also be used for video telephony, provided it is designed accordingly.
[0019] Furthermore, the invention relates to a vehicle with an occupant protection device comprising a folding table with an integrated airbag, and the occupant protection device being assigned to an occupant in a vehicle seat, in particular in a second row of seats. A first part of the airbag deploys from a first surface of the folding table, at least partially, in front of and / or towards the upper body of an occupant in the vehicle seat. A second part of the airbag deploys from a second surface of the folding table towards the legs of the occupant in the vehicle seat and / or, by virtue of its deployment position, assists in positioning the first part of the airbag towards the occupant in the vehicle seat.
[0020] Exemplary embodiments of the invention are explained in more detail below with reference to drawings.
[0021] This shows: Fig. 1 schematically a sectional view of a vehicle with an occupant on a vehicle seat in the rear area of the vehicle, a folding table in its usable position and two airbags of an occupant protection device in their respective effective positions, Fig. 2 schematically the folding table in its stow position with the two airbags in their respective operational positions, Fig. 3 schematically the two airbags and a gas generator, Fig. 4 schematically a first illustration with an occupant protection device in a stowable position of a folding table and a second illustration with the occupant protection device in a sequence of positioning the folding table into a usable position, Fig. 5. Schematically, based on illustrations of the occupant protection device, a process for positioning the folding table from the stow position to the use position in an alternative embodiment, Fig. 6 schematically a sectional view of a support element of the folding table with closed airbag covers, Fig. 7 schematically a sectional view of the support element after activation of an opening mechanism and Fig. Figure 8 schematically shows a sectional view of the support element with the airbag cover open and the airbag in its operational position.
[0022] Corresponding parts are marked with the same reference symbols in all figures.
[0023] Fig. Figure 1 shows, in an exemplary and 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 I in their respective effective positions and another vehicle seat 6, for example a driver's seat of the vehicle 1.
[0024] The airbag 5 has two parts, 5.1 and 5.2. The first part, 5.1, of the airbag, in its deployed or inflated operational position, has a larger volume than the second part, 5.2, of the airbag 5 in its deployed or inflated operational position.
[0025] It is generally known that increasing demands regarding vehicle safety, as well as a desire for more comfortable driving and / or more comfortable automated driving of vehicles 1, require an improvement in occupant protection devices I and a simultaneous increase in the adaptability of occupant protection devices I, for example due to a changed seating position of the occupants 2.
[0026] In particular, it is intended to provide a second occupant in a second row of seats in vehicle 1, as shown in Fig. As shown in Figure 1, it is possible to work relatively conveniently during the operation of the vehicle 1, for example by means of a laptop and / or another input unit.
[0027] 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.
[0028] According to Fig. 1 the folding table 7 is positioned in its usable 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.
[0029] 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 therefore not visible. An exemplary [details omitted] is incorporated into the support element 7.1, in particular into a first surface 7.2 facing the occupant 2. Fig. The first airbag deployment opening 8.1 shown in Figure 9 is introduced, from which the airbag 4 unfolds to assume its operational position. In the usable position of the folding table 7, the first surface 7.2 faces a vehicle roof 1.1.
[0030] A second surface 7.3, opposite the first surface 7.2, also has a second airbag discharge opening 9.1, from which the second part 5.2 of the airbag 5 unfolds to assume its deployment position. The second surface 7.3 is in the operating position of the folding table 7 and thus in the horizontal position of the support element 7.1, facing the legs 2.1 of the occupant 2.
[0031] The airbag discharge openings 8.1 and 9.1 are in the initial position of the airbag 5, i.e. in the uninvoked state, by means of a Fig. The respective airbag covers 8, 9 shown in sections 4 to 9 are closed, for example by means of a so-called respective airbag flap.
[0032] To ensure, as far as possible, that the airbag covers 8, 9 open in the event of a detected impending collision to vehicle 1 or in the event of a detected collision of vehicle 1, a predetermined breaking point and / or a tear seam is incorporated into the respective surface side 7.2 and 7.3 of the support element 7.1, for example, the respective airbag cover 8, 9, in sections around its circumference. A tear seam is chosen in particular 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.
[0033] 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, especially when the respective airbag discharge 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 pose an additional risk of injury to the occupant 2 and / or other occupants.
[0034] The support element 7.1 has, in one embodiment, 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 7.2 of the support element 7.1, which faces the vehicle roof 1.1 in the usable position of the folding table 7, and such a flat user interface can also form the airbag cover 8 of this surface.
[0035] Furthermore, the support element 7.1 is pivotably arranged between two parallel retaining struts 7.4, so that the support element 7.1 can assume its horizontal position in the operating position of the folding table 7. A pivot axis S1 runs parallel to a transverse axis of the vehicle. For example, the support element 7.1 and / or the retaining struts 7.4 have at least one fixing element for fixing the support element 7.1 to the retaining struts 7.4 both in the operating position and in a Fig. 3 stowing positions shown.
[0036] The two support struts 7.4 are pivotally attached at one end to a seat back of the other vehicle seat 6 or to a vehicle floor 1.2. The pivoting range of the support struts 7.4 is limited, for example by means of at least one stop element (not shown in detail). For example, the pivoting range can be adjusted to adapt 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 height. 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.
[0037] 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 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 operational position. The gas generator 10 is housed in the support element 7.1.
[0038] In one embodiment, the two parts 5.1 and 5.2 of the airbag 5 can have controllable valves, making it possible to pressurize 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 effective position. Furthermore, by controlling the valves, it is possible to pressurize both parts 5.1 and 5.2 of the airbag 5 simultaneously or with a time delay.
[0039] In Fig. Figure 4 shows two illustrations, A1 and A2, where the folding table 7 is shown in the first illustration, A1, in its stowed position and the folding table 7 is shown in its working position by means of a dashed line. Fig. For clarity, only the first part 5.1 of the airbag is shown in dashed lines in the two figures A1 and A2.
[0040] A second figure A2 shows a sequence of positioning the folding table 7 from the storage position to the usage position.
[0041] 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 completely arranged between the two retaining struts 7.4.
[0042] The first surface 7.2 of the support element 7.1 is positioned towards the occupant 2 on their vehicle seat 3, so that the first part 5.1 of the airbag 5 deploys towards the occupant 2, in particular towards the upper body of the occupant 2, if necessary. The second surface 7.3 of the support element 7.1 is positioned towards the other vehicle seat 6.
[0043] In the stowed position, the folding table 7 lies essentially completely against the back of a seat back 6.1 of the other vehicle seat or is at least partially arranged within the seat back 6.1, whereby the occupant 2 still has sufficient freedom of movement, in particular with regard to his legs and to the seat back 6.1.
[0044] In the deployment position of the airbag 5, and when the occupant 2 impacts the airbag 5, it is supported in particular by means of the seat back 6.1 of the other vehicle seat 6 and thus stabilized in its deployment position.
[0045] To position the folding table 7 from its stowed position to its usable 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 towards the occupant 2 by means of the pivotally mounted support struts 7.4, for example, until a comfortable position for the occupant 2 is reached. Pivoting the folding table 7 can also be done manually, electrically, pneumatically, and / or hydraulically. Further pivoting of the folding table 7 is limited by at least one stop element, whereby 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.
[0046] Fig. Figure 5 shows, with reference to Figures A1 to A5 of the occupant protection device I, a procedure for positioning the folding table 7 from the stow position to the use position in an alternative embodiment of the folding table 7. Also in the Fig. For clarity, only the first part 5.1 of the airbag is shown in dashed lines in Figures A1 to A5.
[0047] In the first figure A1 of the Fig. Figure 4 shows the folding table 7 in a stowed position, with the support element 7.1 projecting section by section beyond the retaining struts 7.4 towards the vehicle roof 1.1. For example, the support element 7.1 is positioned at the height of a headrest of the other vehicle seat 6. This allows the occupant 2 to comfortably view the user interface, for example, a touch-sensitive display unit and / or another input unit, which is located on the support element 7.1.
[0048] To assume the usable position of the folding table 7, the support element 7.1, as shown in a second figure A2, is pushed between the retaining struts 7.4 towards the vehicle floor 1.2, for example by means of guide rails not shown in detail.
[0049] The support element 7.1 can then be pivoted from bottom to top via the first pivot axis S1, which is moved with the support element 7.1, into an intermediate position shown by means of a dashed line, as shown in a third figure A3.
[0050] Even in the intermediate position, the first surface side 7.2 with the first airbag exit opening 8.1 is positioned towards the vehicle roof 1.1, so that the airbag 5 can unfold upwards between the other vehicle seat 6 and the occupant 2.
[0051] From this intermediate position, the support element 7.1 can be moved upwards between the retaining struts 7.4, i.e. towards the vehicle roof 1.1, as shown in the fourth figure A4.
[0052] The folding table 7 is then pivoted around the second pivot axis S2 towards occupant 2 and the support element 7.1 into its horizontal position, as shown in a fifth figure A5.
[0053] All embodiments have in common that, in order to assume its operational position upon detection of an impending collision to the vehicle 1 or upon detection of a collision to the vehicle 1, the airbag 5, both in its operational position and in its stowed position, deploys its first part 5.1 from the first surface 7.2 of the support element 7.1 of the folding table 7, at least partially in front of and / or towards the upper body of an occupant 2 located on the vehicle seat 3. The second part 5.2 of the airbag 5, in its operational position, deploys from the second surface 7.3 of the support element 7.1 of the folding table 7 towards the legs 2.1 of the occupant 2, and in its stowed position towards the seat back 6.1 of the other vehicle seat 6.
[0054] In particular, the airbag 5 thus deploys from the first airbag discharge opening 8.1 of the first surface 7.2 of the folding table 7, which is in its operating position and the support element 7.1 is therefore in a horizontal position, and assumes its operational position. In the operational 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 by the collision-induced acceleration and impacts the first part 5.1 of the airbag 5. The forward displacement 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.
[0055] Additionally, the second part 5.2 of the airbag 5 of the occupant protection device I deploys from the second surface 7.2 towards the legs 2.1, in particular the thighs of the occupant 2. In a frontal collision of the vehicle 1, the risk of the occupant 2 sliding under the lap belt of their fastened seat belt can be significantly reduced by means of the second part 5.2 of the airbag 5 in its deployed position. In particular, the occupant 2 is secured in their seated position by means of the second part 5.2 of the airbag 5.
[0056] Fig. Figure 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, the folding table 7 lies essentially flat against the seat back 6.1 of the other vehicle seat 6. The first surface 7.2 faces the occupant 2, and the opposite second surface 7.3 rests against the other vehicle seat 6. If the system detects 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 will nevertheless deploy.
[0057] The first part 5.1 of the airbag 5 deploys from the first surface 7.2 of the support element 7.1, which faces 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 7.1 of the support element 7.1, which faces the other vehicle seat 6, so that the second part 5.2 of the airbag 5 is positioned 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 in this operational position the second part 5.2 of the airbag 5 positions the folding table 7, in particular the support element 7.1 and the first part 5.1 of the airbag 5, towards the occupant 2. Specifically, the folding table 7 pivots due to the deployment of the second part 5.The first part 5.1 of the airbag 5 pivots within a predetermined range towards the occupant 2, further limiting the forward displacement of the occupant 2. The first part 5.1 of the airbag 5 rests against the support element 7.1, which rests against the second part 5.2 of the airbag 5, which in turn rests against the seat back 6.1 of the other vehicle seat 6. Thus, a force conversion and transmission to the seat back 6.1 of the other vehicle seat 6 takes place. The second part 5.1 of the airbag 5, facing the occupant 2, is relatively fixed in this deployment position, thereby increasing the level of protection against injury for the occupant 2.
[0058] Preferably, both parts 5.1 and 5.2 of the airbag 5 are controlled separately in the deployment position and in the stowed position, and activated as needed. For example, it is conceivable that if the seat back 6.1 of the other vehicle seat 6 is lowered towards the occupant 2, the second part 5.2 of the airbag 5 is not deployed. It is also conceivable to omit the second part of the airbag 5.2 altogether.
[0059] The Fig. Figures 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 another opening mechanism O2 to the other airbag cover 9.
[0060] The opening mechanism O1 is diagonally opposite the other opening mechanism O2, so that the airbag covers 8, 9 open in opposite directions. For example, the deployment direction of the respective parts 5.1 and 5.2 of the airbag 5 can be determined by means of the respective open airbag cover 8, 9.
[0061] Fig. Figure 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. Figure 7 shows the support element 7.1 with airbag covers 8, 9 still closed and opening mechanisms O1, O2 closed. Fig. Figure 8 shows the support element 7.1 with closed airbag covers 8, 9 and the open opening mechanism O1, whereby the further opening mechanism O2, which is assigned to the second part 5.2 of the airbag 5, is closed. Fig. Figure 8 shows the airbag cover 8 open and the first part 5.1 of the airbag 5 is shown in its operational position.
[0062] 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 of the vehicle 1, so that the respective hook element 11 is controlled and performs a pivoting movement in the event of a detected impending collision of the vehicle 1 or a detected collision of the vehicle 1.
[0063] 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, especially when positioning the support element 7.1.
[0064] If hook 11 is released due to the control signal, the airbag cover 8 pivots open by unfolding the first part 5.1 of the airbag 5 and assumes its operational position, as shown in Figure A5 of the Fig. 5 is shown.
