[Technical field]

[0001] The present invention relates to an occupant protection device for a vehicle with a table. [Background technology]

[0002] In a vehicle having a floor-mounted table installed in the center of the facing seats, a structure in which an airbag protrudes from the underside of the table top toward an occupant seated in the seat in the event of a frontal collision of the vehicle has been known for some time (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-070389 Summary of the Invention [Problem to be solved by the invention]

[0004] However, if the distance between the seated occupant and the table top is too close, there is a concern that the occupant's head, which moves toward the front of the vehicle due to inertia during a frontal collision, may hit the table top and be injured. There is also a concern that the table top may hinder the inflation and deployment of the airbag.

[0005] SUMMARY OF THE PRESENT DISCLOSURE An object of the present invention is to provide an occupant protection device for a vehicle with a table that can prevent the head of an occupant, which moves toward the front of the vehicle due to inertial force, from hitting the table top during a frontal collision of the vehicle. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, a first aspect of the present invention provides an occupant protection device for a vehicle with a table, comprising a vehicle seat provided on a floor of a passenger compartment, and a table having a top plate provided on the front side of the vehicle seat and configured to be slidable toward the front side of the vehicle in the event of a frontal collision of the vehicle.

[0007] According to the first aspect of the invention, in the event of a frontal collision of the vehicle, the top plate of the table provided on the front side of the vehicle seat slides toward the front side of the vehicle, thereby increasing the distance between the top plate and the occupant seated in the vehicle seat, and preventing the head of the occupant, which tends to move toward the front side of the vehicle due to inertial force, from hitting the top plate.

[0008] In addition, a second aspect of the present invention is an occupant protection device for a vehicle with a table, which is the first aspect of the occupant protection device for a vehicle with a table, and is configured so that the top plate slides toward the front of the vehicle by inertial force or a mechanical mechanism.

[0009] According to the second aspect of the invention, the top plate is configured to slide toward the front side of the vehicle by inertial force or a mechanical mechanism, which simplifies the structure compared to a configuration in which the top plate is slid by an electric mechanism, for example.

[0010] In addition, a third aspect of the present invention is an occupant protection device for a vehicle with a table of the first or second aspect, wherein the table is provided on the floor or the vehicle seat, and has a preventing mechanism that prevents the top plate, which has slid toward the front of the vehicle, from sliding toward the rear of the vehicle due to recoil.

[0011] According to the third aspect of the invention, the table is provided with a blocking mechanism that blocks the top plate, which has slid toward the front of the vehicle, from sliding toward the rear of the vehicle due to reaction, thereby preventing the head of the occupant from hitting the top plate even in the later stages of the collision.

[0012] In addition, an occupant protection device for a vehicle with a table of a fourth aspect of the present invention is an occupant protection device for a vehicle with a table of the first or second aspect, wherein the table is provided on the floor and has a limiting portion that limits the top plate from sliding more than a predetermined amount toward the front of the vehicle.

[0013] According to the fourth aspect of the invention, the limiting portion provided on the table limits the top plate from sliding toward the front of the vehicle by more than a predetermined amount, thereby preventing the top plate, which slides toward the front of the vehicle, from hitting an occupant sitting in the vehicle seat on the opposite side of the vehicle seat.

[0014] In addition, an occupant protection device for a vehicle with a table of a fifth aspect of the present invention is an occupant protection device for a vehicle with a table of any one of the first to fourth aspects, and is equipped with an airbag that inflates and deploys between the top plate that slides toward the front of the vehicle and an occupant seated in the vehicle seat.

[0015] According to the fifth aspect of the invention, the airbag inflates and deploys between the top plate that slides toward the front of the vehicle and the occupant sitting in the vehicle seat. That is, the airbag inflates and deploys in the space expanded by the top plate sliding toward the front of the vehicle. Therefore, there is no risk that the top plate will hinder the inflation and deployment of the airbag, and the occupant is effectively restrained.

[0016] In addition, an occupant protection device for a vehicle with a table of a sixth aspect of the present invention is an occupant protection device for a vehicle with a table of the fifth aspect, wherein the airbag is configured to be able to restrain at least the head and chest of the occupant.

[0017] According to the sixth aspect of the invention, the airbag restrains at least the head and chest of the occupant. That is, the airbag restrains not only the head of the occupant but also the chest. Therefore, there is no risk of the occupant's neck bending backward significantly.

[0018] In addition, an occupant protection device for a vehicle with a table of a seventh aspect of the present invention is an occupant protection device for a vehicle with a table of the fifth or sixth aspect, wherein the airbag is mounted on a side door, the table, the vehicle seat, the ceiling of the passenger compartment, the center console, or a seat belt.

[0019] According to the seventh aspect of the invention, the airbag is mounted on a side door, a table, a vehicle seat, a ceiling of a vehicle compartment, a center console, or a seat belt. Therefore, the airbag is appropriately inflated and deployed in the space expanded by sliding the top plate toward the front side of the vehicle. Effect of the Invention

[0020] As described above, according to the present invention, the head of an occupant moving toward the front of the vehicle due to inertial force during a frontal collision of the vehicle can be prevented from hitting the table top. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. For convenience of explanation, the arrow UP shown in each drawing indicates the upward direction of the vehicle and the vehicle seat, the arrow FR indicates the forward direction of the vehicle and the vehicle seat, and the arrow RH indicates the rightward direction of the vehicle and the vehicle seat. Therefore, in the following description, when the directions of up / down, front / rear, and left / right are described without special mention, they refer to up / down, front / rear, and left / right of the vehicle and the vehicle seat. In addition, the left / right direction is synonymous with the vehicle width direction and the seat width direction.

[0023] First Embodiment First, a first embodiment will be described. As shown in Fig. 1, an occupant protection device 20 according to the first embodiment includes a vehicle seat 12 and a table 30 provided on a floor 22 of a vehicle interior of an autonomous driving vehicle 10 (hereinafter referred to as "vehicle 10"). The table 30 is installed on the floor 22 in front of the rear vehicle seat 12, and the front vehicle seat 12 is configured to face the rear vehicle seat 12 with the table 30 in between.

[0024] Each vehicle seat 12 has a seat cushion 14 on which an occupant sits (supporting the occupant's buttocks and thighs), a seat back 16 that is provided on the rear side of the seat cushion 14 so as to be rotatable about an axial direction that is the seat width direction and supports the occupant's back, and a headrest 18 that is provided on the upper end of the seat back 16 so as to be able to rise and fall and supports the occupant's head. In the following description, the front vehicle seat 12 will be referred to as the "vehicle seat 12F" when being described separately from the rear vehicle seat 12.

[0025] In each figure, a crash test dummy (human dummy) is shown seated on the seat cushion 14 of the vehicle seat 12 as a model of the occupant (seater) to be protected. The dummy is, for example, a frontal crash test dummy (Hybrid III) AM50 (50th percentile of American adult males). The dummy is seated in a standard seating position defined by the crash test method, and the vehicle seat 12 is located at a reference setting position corresponding to the seating position. Hereinafter, the dummy will be referred to as "occupant P."

[0026] In addition, an occupant P seated on the seat cushion 14 of the vehicle seat 12 is restrained to the vehicle seat 12 by a seat belt 26 provided in a seat belt device 24. The seat belt device 24 is a three-point seat belt device, and is a so-called seat-attached seat belt device in which a retractor and an anchor, not shown, and a buckle are each provided on the vehicle seat 12.

[0027] 2 to 4, the table 30 has a support pillar 28 erected on the floor 22, a table body 32 integrally provided on the upper end of the support pillar 28, and a top plate 40 provided so as to be slidable relative to the table body 32. Note that "support pillar 28 erected on the floor 22" also includes a case in which the support pillar 28 is attached to a support member (not shown) provided on the lower side of the floor 22 and erected by penetrating a through-hole (not shown) formed in the floor 22.

[0028] The table body 32 is formed in a rectangular housing shape in plan view with an opening on the rear side, and has a bottom plate 34, a fixed top plate 36, left and right side plates 35, and a front plate 38 serving as a limiting portion, which will be described later. The top plate 40 is formed in a rectangular flat plate shape of a size that can be stored inside the table body 32, and is configured to normally protrude rearward from the opening 32A of the table body 32, and to be slid forward by the inertial force of the impact in the event of a frontal collision of the vehicle 10.

[0029] 3, a blocking mechanism 50 is provided in the center in the left-right direction on the rear side of the inner surface (lower surface) of the fixed top plate 36. The blocking mechanism 50 is composed of a stopper portion 52 and a compression coil spring 54 as a biasing member that biases the stopper portion 52 downward.

[0030] The compression coil spring 54 is housed in a hole 36A formed on the inner surface of the fixed top plate 36. The stopper portion 52 is formed in a substantially quarter-circular shape in a side view, and is configured to be able to enter and exit from the hole 36A with the curved portion 52A facing backward (with the flat portion 52B facing forward).

[0031] The top plate 40 is configured to maintain a state in which it protrudes rearward from the opening 32A by abutting the front upper edge 40A against the curved surface portion 52A of the stopper portion 52 (see FIG. 3(A)). When the vehicle 10 experiences a frontal collision, the top plate 40 slides forward due to inertial force, and at that time, the curved surface portion 52A of the stopper portion 52 is pressed forward by the front upper edge 40A.

[0032] As a result, the stopper portion 52 rises against the biasing force of the compression coil spring 54 and enters the hole portion 36A, allowing the top plate 40 to slide forward (see FIG. 3(B)). As will be described later, when the rear surface 40B of the top plate 40 exceeds the flat surface portion 52B of the stopper portion 52, the stopper portion 52 is lowered by the biasing force of the compression coil spring 54 and protrudes from the hole portion 36A (see FIG. 3(C)).

[0033] The top plate 40 is configured such that its front surface 40F comes into contact with the inner surface (rear surface) 38F of the front plate 38, thereby restricting its forward sliding. In other words, the front plate 38 serves as a restricting portion that restricts the top plate 40 from sliding forward by more than a predetermined amount. The length of the top plate 40 in the front-rear direction is formed to be equal to or shorter than the length from the inner surface 38F of the front plate 38 to the flat surface portion 52B of the stopper portion 52 in a side view.

[0034] Therefore, when the rear surface 40B of the top plate 40 exceeds the flat surface 52B of the stopper portion 52, the stopper portion 52 is lowered by the biasing force of the compression coil spring 54 and protrudes from inside the hole portion 36A. As a result, when the top plate 40 slides forward (the front plate 38 restricts the front plate 40 from sliding forward), the rear surface 40B comes into contact with the flat surface 52B of the stopper portion 52, so that the top plate 40 is prevented from sliding backward due to the reaction force.

[0035] 4, a plurality of rollers 42 with their rotation axes extending in the up-down direction are rotatably attached at predetermined intervals to the left and right side surfaces 40S of the top plate 40. Each roller 42 rolls along the inner surface 35S of the left and right side plates 35, allowing the top plate 40 to slide smoothly. A gripping portion 44 that can be gripped by fingers is provided on the rear surface 40B of the top plate 40.

[0036] The gripping parts 44 are formed, for example, from a cloth material in a generally "U" shape in plan view, and are provided in a pair with a gap between them on the left and right. This makes it possible to grasp the gripping parts 44 and pull out the tabletop 40 while lifting the stopper parts 52 with fingers against the biasing force of the compression coil springs 54. In other words, the tabletop 40 is configured to be able to be stored inside the table main body 32 even under normal circumstances.

[0037] 2(B), an airbag device 60 is mounted on a side door (not shown) of the vehicle 10. The airbag device 60 includes an airbag 62 that is normally folded, and an inflator (not shown) that instantly supplies gas to the airbag 62 when the vehicle 10 is involved in a frontal collision. The vehicle 10 is also equipped with a control device (ECU) that controls the operation of the inflator.

[0038] The control device is electrically connected to the inflator and a collision sensor (not shown) and is configured to be able to detect a frontal collision of the vehicle 10. The control device is configured to activate the inflator when it detects a frontal collision of the vehicle 10 based on information from the collision sensor (hereinafter referred to as "frontal collision").

[0039] The inflator is, for example, a combustion-type or cold gas-type cylinder-type inflator, and is configured to generate gas by being activated by the control device when a frontal collision occurs for the vehicle 10. Note that the types of frontal collisions of the vehicle 10 in which the control device activates the inflator include offset frontal collisions such as oblique collisions and minute-wrap collisions, in addition to full-wrap frontal collisions.

[0040] The airbag 62 is configured to split open a door trim (not shown) of the side door by inflation pressure caused by gas supplied from an inflator, and to inflate and deploy (deploy and inflate) toward at least the front of the head and chest of an occupant P seated in the vehicle seat 12. The door trim is formed with a tear line (not shown) as a breaking portion for splitting, and the airbag 62 is configured to inflate and deploy by breaking the tear line.

[0041] The airbag 62 after inflation and deployment is formed to a size (height, width, thickness) capable of restraining at least the head and chest of the occupant P who tends to move forward due to inertial force in the event of a frontal collision of the vehicle 10, and is compressively deformable by being pressed against at least the head and chest of the occupant P (see FIG. 2(B)). The airbag 62 is formed into a bag shape by overlapping two base fabrics made of, for example, a polyamide or polyester fabric material, and sewing the periphery thereof.

[0042] Next, the operation of the occupant protection device 20 for the vehicle 10 with the table 30 according to the first embodiment configured as above will be described.

[0043] A table 30 is installed on the floor 22 of the vehicle compartment, in front of the vehicle seat 12. A top plate 40 protrudes rearward (toward the occupant P) from an opening 32A of a table body 32 of the table 30. In this state, the top plate 40 has only a front upper edge 40A in contact with the curved surface portion 52A of the stopper portion 52, and a plurality of rollers 42 are provided on a side surface 40S.

[0044] Therefore, the top plate 40 protruding from the opening 32A of the table body 32 of the table 30 towards the occupant P slides forward due to the inertial force caused by the impact during a frontal collision of the vehicle 10. This increases the distance between the top plate 40 and the occupant P seated in the vehicle seat 12, preventing the head of the occupant P, which is moving forward due to the inertial force, from hitting the top plate 40 (reducing or avoiding the risk of injury to the head of the occupant P).

[0045] Furthermore, in the event of a frontal collision of the vehicle 10, the inflator is activated by the control of the control device, and gas is ejected from the inflator. The gas ejected from the inflator is supplied to the airbag 62. Then, a tear line formed on the door trim of the side door is subjected to the inflation pressure of the airbag 62 and ruptures, and the airbag 62 is inflated and deployed toward at least the head and chest of the occupant P.

[0046] Here, the top plate 40 of the table 30 has already slid forward due to the inertial force at the time of the frontal collision of the vehicle 10. Therefore, the airbag 62 can be inflated and deployed between the top plate 40 (table body 32) that has slid forward and the occupant P seated in the vehicle seat 12.

[0047] In particular, since the airbag 62 is mounted on the side door, it can be inflated and deployed quickly and appropriately in the space expanded by sliding the top plate 40 forward. In other words, there is no risk of the airbag 62 interfering with the top plate 40 (there is no risk of the airbag 62 being hindered from inflating and deploying by the top plate 40), and the airbag 62 can be inflated and deployed quickly and appropriately forward of at least the head and chest of the occupant P.

[0048] This allows the airbag 62 to effectively receive the load from the occupant P who moves forward due to the inertial force caused by the impact at the time of a frontal collision of the vehicle 10. Moreover, since the airbag 62 compresses and deforms to restrain not only the head but also the chest of the occupant P, there is no risk of the occupant P bending backward significantly, and it is possible to suppress or prevent the occurrence of brain damage caused by centrifugal force.

[0049] Thus, according to the first embodiment, even if the top plate 40 of the table 30 installed on the floor 22 is positioned in front of the occupant P seated in the vehicle seat 12 under normal circumstances, in the event of a frontal collision of the vehicle 10, the head of the occupant P moving due to inertia can be prevented from hitting the top plate 40, and further, at least the head and chest of the occupant P can be effectively and appropriately restrained by the airbag 62.

[0050] In addition, since the top plate 40 is configured to slide forward by inertial force, the structure is simpler than, for example, a configuration in which the top plate 40 is slid by an electric mechanism. In addition, since the table 30 is provided with a front plate 38, the top plate 40 is restricted from sliding forward by more than a predetermined amount. Therefore, as shown in FIG. 2, the top plate 40, which slides forward, can be prevented from hitting the occupant P seated in the vehicle seat 12F on the opposite side of the vehicle seat 12.

[0051] In addition, the top plate 40 that has slid forward is prevented from sliding backward due to reaction by the blocking mechanism 50 (stopper portion 52) provided on the table 30. Therefore, for example, in the later stages of a frontal collision of the vehicle 10 in which the airbag 62 is not inflated and deployed, the top plate 40 that has slid forward slides backward due to reaction, and the head of the occupant P hits the top plate 40, which is prevented from occurring.

[0052] <Second embodiment> Next, a second embodiment will be described. Note that the same reference numerals are used for the same parts as those in the first embodiment, and detailed descriptions (including common functions) will be omitted as appropriate.

[0053] As shown in Figure 5, this second embodiment differs from the first embodiment only in that a pair of tension coil springs 46 serving as biasing members for biasing the top plate 40 forward are installed at a distance from each other on the left and right between the inner surface 38F of the front plate 38 of the table body 32 and the front surface 40F of the top plate 40, and in that a pair of protrusions 48 for preventing the top plate 40 from sliding forward are erected at a distance from each other on the left and right on the rear side of the inner surface (top surface) of the bottom plate 34.

[0054] The protrusion 48 is formed of a resin material, for example, in a flat plate shape, so that it is cut (broken) by the top plate 40 attempting to slide forward due to the force of inertia during a frontal collision of the vehicle 10 at a level at which the airbag 62 deploys. That is, since the input load from the top plate 40 to the protrusion 48 is determined by the weight of the top plate 40 and the acceleration during a frontal collision of the vehicle 10, the weight of the top plate 40 and the shape and strength of the protrusion 48 are set (adjusted) so that it will break at an input load at a level at which the airbag 62 deploys (but not at an input load at a level at which the airbag 62 does not deploy).

[0055] The biasing force of the tension coil spring 46 is set to an extent that assists the sliding caused by the inertial force of the tabletop 40 so that the tabletop 40 with the protrusion 48 cut (broken) can reliably slide forward. Therefore, the protrusion 48 will not be broken by the tabletop 40 being pulled forward by the biasing force of the tension coil spring 46. The tension coil spring 46 is an example of a mechanical mechanism.

[0056] According to the second embodiment configured as described above, the top plate 40 of the table 30 is configured to slide forward by cutting the protrusion 48 due to the inertial force of the vehicle 10 and being pulled by the tension coil spring 46 when the vehicle 10 crashes in the front, so that the structure is simplified compared to a configuration in which the top plate 40 is slid by an electric mechanism, for example. The shape of the protrusion 48 is not limited to the flat plate shape shown in the figure, and it may be any shape that is easily cut by the top plate 40 attempting to slide forward due to the inertial force.

[0057] <Third embodiment> Next, a third embodiment will be described. Note that the same reference numerals are used for the same parts as those in the first embodiment, and detailed descriptions (including common functions) will be omitted as appropriate.

[0058] 6, the third embodiment differs from the first embodiment only in that the top plate 40 is forcibly slid forward by a known pretensioner mechanism 56, which is an example of a mechanical mechanism, in the event of a frontal collision of the vehicle 10. More specifically, one end of a wire 58 is attached to the front surface 40F of the top plate 40, and the other end of the wire 58 is connected to the pretensioner mechanism 56.

[0059] The pretensioner mechanism 56 has, for example, a gas generator (not shown) that is activated when the vehicle 10 experiences a frontal collision, and a tensioning mechanism (not shown) that instantly pulls the wire 58 by the activation of the gas generator. The tensioning mechanism may include, for example, a rack and pinion.

[0060] That is, the other end of the wire 58 is attached to the outer circumferential surface of a take-up roll (not shown), and the take-up roll is rotated by the rotation of the pinion. The rack meshed with the pinion is instantaneously protruded by the operation of the gas generator.

[0061] According to the third embodiment configured as described above, in the event of a frontal collision of the vehicle 10, the gas generator is activated to instantly rotate the winding roll via the rack and pinion, thereby instantly winding and pulling the wire 58, and instantly and forcibly sliding the top plate 40 forward.

[0062] The pretensioner mechanism 56 may be provided inside the support pillar 28 as shown in FIG. 6(A) and configured to slide the top plate 40 forward by pulling the wire 58 downward, or may be provided inside the front plate 38 as shown in FIG. 6(B) and configured to slide the top plate 40 forward by pulling the wire 58 to either the left or right side (the left side in the illustrated example).

[0063] When the pretensioner mechanism 56 is provided inside the support pillar 28, a passage 28A and a hole 34A for passing the wire 58 are formed in the support pillar 28 and the bottom plate 34, respectively, so as to communicate with each other. When the pretensioner mechanism 56 is provided inside the front plate 38, the front plate 38 is formed thick, and a passage 38A for passing the wire 58 is formed in the front plate 38.

[0064] The control device in the third embodiment is electrically connected to a camera (not shown) and is configured to be able to predict (foresee) the unavoidability of a frontal collision of the vehicle 10. In other words, the control device in the third embodiment is configured to activate the inflator and pretensioner mechanism 56 not only when a frontal collision of the vehicle 10 is detected, but also when a frontal collision of the vehicle 10 is predicted, based on information from the collision sensor and the camera. Note that a prediction of a frontal collision of the vehicle 10 is also referred to as "at the time of a frontal collision."

[0065] <Fourth embodiment> Next, a fourth embodiment will be described. Note that the same reference numerals are used for the same parts as those in the first to third embodiments, and detailed descriptions (including common functions) will be omitted as appropriate.

[0066] 7, the fourth embodiment differs from the first to third embodiments only in that the table 30 is integrally provided with the vehicle seat 12 that is not slidable in the front-rear direction. Specifically, the support pillar 28 of the table 30 is erected at the front of the side portion 15 provided on the outer side in the seat width direction of the seat cushion 14 of the vehicle seat 12, for example.

[0067] According to the fourth embodiment configured in this manner, in the event of a frontal collision of the vehicle 10, the top plate 40 protruding toward the occupant P slides forward, so that a space can be formed in front of at least the head and chest of the occupant P, and the airbag 62 that inflates and deploys from the side door can be positioned in front of at least the head and chest of the occupant P.

[0068] <Fifth embodiment> Finally, a fifth embodiment will be described below. Note that the same reference numerals are used for the same parts as those in the fourth embodiment, and detailed descriptions (including common functions) will be omitted as appropriate.

[0069] 8, the fifth embodiment differs from the fourth embodiment only in that the airbag device 60 is mounted on the table body 32 of the table 30 and the vehicle seat 12 is configured to be slidable in the front-rear direction. Specifically, the airbag device 60 is embedded in the rear side of the bottom plate 34 or the fixed top plate 36.

[0070] According to the fifth embodiment configured in this manner, in the event of a frontal collision of the vehicle 10, the table top 40 protruding toward the occupant P slides forward, so that a space can be formed in front of at least the head and chest of the occupant P, and the airbag 62 that inflates and deploys from the table main body 32 can be positioned in front of at least the head and chest of the occupant P.

[0071] Furthermore, since the airbag device 60 is mounted on the table body 32 (bottom plate 34 or fixed top plate 36) of the table 30, which slides in the fore-and-aft direction integrally with the vehicle seat 12, the airbag 62 can be quickly and appropriately inflated and deployed in the space expanded by the top plate 40 sliding forward, regardless of the fore-and-aft position of the vehicle seat 12.

[0072] Although the passenger protection device 20 for the vehicle 10 with the table 30 according to this embodiment has been described above with reference to the drawings, the passenger protection device 20 for the vehicle 10 with the table 30 according to this embodiment is not limited to the one shown in the drawings, and the design can be appropriately modified within the scope of the present invention. For example, the mechanical mechanism is not limited to the tension coil spring 46 and the pretensioner mechanism 56.

[0073] Furthermore, the top plate 40 is not limited to a configuration in which multiple rollers 42 provided on the side surface 40S roll and slide on the inner surface 35S of the side panel 35 of the table body 32, but may be configured, for example, in such a way that a fitting portion (not shown) provided on the side surface 40S of the top plate 40 slidably fits into a rail (not shown) provided on the inner surface 35S of the side panel 35 and slides.

[0074] Furthermore, the airbag device 60 (airbag 62) is not limited to being mounted on a side door or the table body 32 of the table 30, but may be mounted on the vehicle seat 12, the ceiling of the vehicle compartment (not shown), the center console (not shown), or the seat belt 26 (lap belt). In any case, the airbag 62 is inflated and deployed in the space expanded by sliding the top plate 40 forward, resulting in the airbag 62 having a shape as shown in Fig. 2(B) and Fig. 7(B). Thus, in this embodiment, there are many options for the location where the airbag device 60 is mounted, and there is a high degree of freedom in design.

[0075] Furthermore, in at least the fourth embodiment out of the fourth and fifth embodiments, the front plate 38 may not be provided on the table main body 32. In particular, when the table 30 is provided on a vehicle seat 12 that is configured to be non-slidable, the table main body 32 is sufficiently separated from the occupant P seated on the vehicle seat 12F on the opposite side of the vehicle seat 12. Therefore, even if the front plate 38 is not provided on the table main body 32, the top plate 40 that slides forward will not hit the occupant P seated on the vehicle seat 12F.
