Description

Technical Field

[0001] The present disclosure relates to an occupant protection device of a vehicle with an attached table. Background Art

[0002] A structure has long been known in which, in a vehicle in which a table attached to the floor is provided at the center of face-to-face seats, an airbag protrudes from the lower surface of the top plate of the table toward a passenger seated on the seat in the event of a head-on collision of the vehicle (for example, refer to Japanese Patent Gazette No. 2021-070389). Summary of the invention

[0003] Problems to be solved by the invention

[0004] However, if the distance between the occupant sitting on the seat and the top plate of the table is too close, the head of the occupant moving toward the front side of the vehicle due to inertia may hit the top plate of the table and be injured. In addition, the top plate of the table may also hinder the expansion and deployment of the airbag.

[0005] Therefore, an object of the present disclosure is to obtain an occupant protection device for a vehicle equipped with a table that can prevent the head of an occupant who moves toward the front side of the vehicle due to inertia from hitting the top plate of the table during a frontal collision of the vehicle.

[0006] Means for solving problems

[0007] A first embodiment of an occupant protection device for a vehicle with an attached table comprises: a vehicle seat disposed on a floor of a vehicle compartment; and a table disposed on a vehicle front side of the vehicle seat and having a top plate configured to slide toward the vehicle front side in the event of a frontal collision of the vehicle.

[0008] According to the disclosure of the first mode, when the vehicle is hit head-on, the top plate of the table provided on the vehicle front side of the vehicle seat slides toward the vehicle front side. As a result, the distance between the top plate and the occupant sitting on the vehicle seat is increased, preventing the head of the occupant who is about to move toward the vehicle front side due to inertia from hitting the top plate.

[0009] The occupant protection device for a vehicle equipped with a table according to a second aspect is, in the first aspect, wherein the top plate is configured to slide toward the front side of the vehicle by inertial force or a mechanical mechanism.

[0010] According to the disclosure of the second aspect, the roof panel is configured to slide toward the front side of the vehicle by inertial force or a mechanical mechanism, so that the structure is simplified compared to a structure that slides by, for example, an electric mechanism.

[0011] The third mode of the occupant protection device of a vehicle with an attached table is that in the first mode or the second mode, the table is arranged on the floor or the vehicle seat, and has a preventing mechanism for preventing the top plate sliding toward the front side of the vehicle from sliding toward the rear side of the vehicle due to a reaction force.

[0012] According to the disclosure of the third aspect, the top plate that has slid toward the front of the vehicle is prevented from sliding toward the rear of the vehicle due to the reaction force by the blocking mechanism provided in the table. Therefore, even in the later stage of the collision, the head of the occupant can be prevented from hitting the top plate.

[0013] A fourth aspect of the occupant protection device for a vehicle equipped with a table is, in the first aspect or the second aspect, wherein the table is provided on the floor and has a restricting portion that restricts the top plate from sliding toward the front of the vehicle by more than a predetermined amount.

[0014] According to the disclosure of the fourth mode, the top plate is restricted by the restriction portion provided in the table so as not to slide more than a predetermined amount toward the front of the vehicle. Therefore, the top plate sliding toward the front of the vehicle can be prevented from hitting an occupant seated on the vehicle seat on the opposite side of the vehicle seat.

[0015] A fifth aspect of the occupant protection device for a vehicle with a table is, in the first aspect or the second aspect, provided with an airbag that is inflated and deployed between the roof panel that slides toward the front side of the vehicle and an occupant seated on the vehicle seat.

[0016] According to the disclosure of the fifth embodiment, the airbag is inflated and deployed between the top plate sliding toward the front side of the vehicle and the occupant sitting on the vehicle seat. That is, the airbag is inflated and deployed in the space expanded by the top plate sliding toward the front side of the vehicle. Therefore, the top plate cannot hinder the inflation and deployment of the airbag, and the occupant is effectively restrained.

[0017] A sixth aspect of the occupant protection device for a vehicle equipped with a table is the occupant protection device according to the fifth aspect, wherein the airbag is configured to restrain at least a head and a chest of the occupant.

[0018] According to the disclosure of the sixth aspect, the airbag restrains at least the head and chest of the occupant. That is, the airbag restrains not only the head but also the chest of the occupant. Therefore, the occupant's neck will not bend backward.

[0019] A seventh aspect of the occupant protection device for a vehicle with a table is that, in the fifth aspect, the airbag is mounted on a side door, the table, the vehicle seat, a roof of the vehicle compartment, a center console, or a seat belt.

[0020] According to the disclosure of the seventh aspect, the airbag is mounted on a side door, a table, a vehicle seat, a roof of a vehicle compartment, a center console, or a seat belt, so that the airbag can be appropriately inflated and deployed in the space expanded by the top plate sliding toward the front side of the vehicle.

[0021] Effects of the Invention

[0022] As described above, according to the present disclosure, it is possible to prevent the head of the occupant, which moves toward the front side of the vehicle due to the inertial force, from hitting the top plate of the table during a head-on collision of the vehicle.

[0038] Hereinafter, the embodiments of the present disclosure will be described in detail based on the accompanying drawings. In addition, for the convenience of description, the arrow mark UP appropriately shown in each figure is set to the upper direction of the vehicle and the vehicle seat, the arrow mark FR is set to the front direction of the vehicle and the vehicle seat, and the arrow mark RH is set to the right direction of the vehicle and the vehicle seat. Therefore, in the following description, when the up-down, front-back, left-right directions are recorded without special description, they are set to represent the up-down, front-back, left-right in the vehicle and the vehicle seat. In addition, the left-right direction has the same meaning as the vehicle width direction and the seat width direction.

[0039] <First embodiment>

[0040] First, the first embodiment will be described. Figure 1 As shown, the occupant protection device 20 involved in the first embodiment is configured to include a vehicle seat 12 and a table 30 provided on a floor 22 of a vehicle compartment of an autonomous driving vehicle 10 (hereinafter referred to as "vehicle 10"). The table 30 is provided on the floor 22 in front of the rear vehicle seat 12, and the front vehicle seat 12 is structured to face the rear vehicle seat 12 across the table 30.

[0041] Each vehicle seat 12 includes a seat cushion 14 on which an occupant sits (supporting the occupant's buttocks and thighs); a seat back 16 which is provided at the rear side of the seat cushion 14 so as to be rotatable with the seat width direction as an axial direction and supports the occupant's back; and a headrest 18 which is provided at the upper end of the seat back 16 so as to be liftable and supports the occupant's head. In the following description, the front vehicle seat 12 is referred to as a "vehicle seat 12F" when distinguished from the rear vehicle seat 12.

[0042] In addition, in each figure, as a model of the occupant (seat occupant) to be protected, a collision test dummy (human model) is shown sitting on the seat cushion 14 of the vehicle seat 12. The dummy is, for example, an AM50 (50th percentile of American adult males) of a frontal collision test dummy (Hybrid III). The dummy sits in a standard sitting posture prescribed in the collision test law, and the vehicle seat 12 is located at a reference setting position corresponding to the sitting posture. Hereinafter, the dummy is referred to as "occupant P".

[0043] Furthermore, the occupant P sitting on the seat cushion 14 of the vehicle seat 12 is restrained on the vehicle seat 12 by the seat belt 26 provided in the seat belt device 24. The seat belt device 24 is a three-point seat belt device, and is a seat belt device attached to the vehicle seat 12, in which a retractor, an anchor point, and a buckle are all provided.

[0044] like FIG. 2A to FIG. 4B As shown, the table 30 includes a support column 28 provided vertically on the floor 22, a table body 32 provided integrally with the upper end of the support column 28, and a top plate 40 provided slidably with respect to the table body 32. In addition, the "support column 28 provided vertically on the floor 22" also includes a case where the support column 28 is mounted on a supporting member provided on the lower side of the floor 22 and is provided vertically through a through hole formed in the floor 22.

[0045] The table body 32 is formed into a rectangular frame shape with an opening on the rear side when viewed from above, and has a bottom plate 34, a fixed top plate 36, left and right side plates 35, and a front plate 38 as a limiting portion described later. The top plate 40 is formed into a rectangular flat plate of a size that can be accommodated inside the table body 32, and is configured to protrude from the opening 32A of the table body 32 to the rear side in normal times, and to be able to slide to the front side by the inertial force of the impact when the vehicle 10 collides head-on.

[0046] like FIG. 3A to FIG. 3CAs shown, a blocking mechanism 50 is provided at the left-right center of 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 for biasing the stopper portion 52 downward.

[0047] The compression coil spring 54 is accommodated in the 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 move in and out of the hole 36A with the curved surface portion 52A facing the rear side (with the flat surface portion 52B facing the front side).

[0048] The top plate 40 is structured such that the front upper edge portion 40A thereof abuts against the curved surface portion 52A of the stopper portion 52, thereby maintaining a state of protruding from the opening portion 32A toward the rear side (see FIG. 1 ). Figure 3A ). Furthermore, when the vehicle 10 is subjected to a head-on collision, the top plate 40 tends to slide forward due to inertia, and at this time, the curved surface portion 52A of the stopper portion 52 is pressed forward by the front upper edge portion 40A.

[0049] Thus, the stopper portion 52 is structured so as to overcome the urging force of the compression coil spring 54, rise and enter into the hole portion 36A, and allow the top plate 40 to slide forward (see Figure 3B ). In addition, as described later, 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 moved downward by the force of the compression coil spring 54 and protrudes from the hole 36A (see Figure 3C ).

[0050] In addition, the top plate 40 is structured so that its sliding toward the front side is restricted by the front surface 40F thereof contacting the inner surface (rear surface) 38F of the front plate 38. That is, the front plate 38 serves as a restriction portion that restricts the sliding of the top plate 40 toward the front side by a predetermined amount or more. Furthermore, the length of the top plate 40 along the front-to-back direction is formed to be the same as 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 when viewed from the side.

[0051] Therefore, when the rear surface 40B of the top plate 40 exceeds the flat surface 52B of the stopper 52, the stopper 52 is lowered and protrudes from the hole 36A by the urging force of the compression coil spring 54. As a result, the top plate 40 that has slid forward (the forward sliding is restricted by the front plate 38) is prevented from sliding backward due to the reaction force by the contact between its rear surface 40B and the flat surface 52B of the stopper 52.

[0052] In addition, as shown in Fig. 4, a plurality of rollers 42 are rotatably mounted on the left and right side surfaces 40S of the top plate 40 at predetermined intervals with the vertical direction as the rotation axis direction. Each roller 42 is configured to enable the top plate 40 to slide smoothly by rolling along the inner surface 35S of the left and right side plates 35. In addition, a gripping portion 44 that can be gripped with fingers is provided on the rear surface 40B of the top plate 40.

[0053] The gripping portion 44 is formed of, for example, a cloth so as to be substantially U-shaped when viewed from above, and a pair of gripping portions 44 are provided at intervals on the left and right. Thus, the top plate 40 can be pulled out by holding the gripping portion 44 with fingers while the stopper portion 52 overcomes the force of the compression coil spring 54 and rises. That is, the top plate 40 is configured to be retractable inside the table body 32 even in normal conditions.

[0054] In addition, if Figure 2B As shown, an airbag device 60 is mounted on a side door of the vehicle 10. The airbag device 60 includes an airbag 62 which is normally folded, and an inflator which instantly supplies gas to the airbag 62 in the event of a frontal collision of the vehicle 10. Furthermore, the vehicle 10 includes a control device (ECU) which controls the operation of the inflator.

[0055] The control device is electrically connected to the inflator and the collision sensor, and is configured to detect a frontal collision of the vehicle 10. When a frontal collision of the vehicle 10 is detected based on information from the collision sensor (hereinafter referred to as "frontal collision"), the control device operates the inflator.

[0056] The inflator is a cylinder-type inflator of, for example, a combustion type or a cold air type, and is operated by the control device to generate gas in the event of a frontal collision of the vehicle 10. In addition, the frontal collision of the vehicle 10 in which the control device operates the inflator includes, in addition to a full overlap frontal collision, an offset frontal collision such as an oblique collision or a small overlap collision.

[0057] The airbag 62 ruptures the door trim of the side door by the inflation pressure generated by the gas supplied from the inflator, and expands and deploys (expands and expands) toward the front side of at least the head and chest of the occupant P sitting on the vehicle seat 12. In addition, a tear line is formed on the door trim as a breaking portion for rupture, and the airbag 62 breaks the tear line and expands and deploys.

[0058] The airbag 62 after inflating and deploying is formed to have a size (height, width, thickness) that can restrain at least the head and chest of the occupant P that tend to move forward due to inertia force during a frontal collision of the vehicle 10, and can be compressed and deformed by being pressed by at least the head and chest of the occupant P (see Figure 2B ) The airbag 62 is formed into a bag shape by overlapping two base fabrics made of polyamide or polyester fabrics and sewing the peripheral edges thereof, for example.

[0059] Next, the operation of the occupant protection device 20 of the vehicle 10 with the table 30 according to the first embodiment configured as described above will be described.

[0060] A table 30 is provided on the floor 22 of the vehicle compartment and in front of the vehicle seat 12. A top plate 40 protrudes from an opening 32A of a table body 32 of the table 30 toward the rear (the passenger P side). In this state, only the front upper edge 40A of the top plate 40 abuts against the curved surface 52A of the stopper portion 52, and a plurality of rollers 42 are provided on the side surface 40S thereof.

[0061] Therefore, the top plate 40 protruding from the opening 32A of the table body 32 of the table 30 toward the occupant P slides forward due to the inertial force generated by the impact during the head-on collision of the vehicle 10. As a result, the distance between the top plate 40 and the occupant P seated on the vehicle seat 12 is increased, thereby preventing the head of the occupant P that is about to move forward due to the inertial force from hitting the top plate 40 (the risk of head injury to the occupant P can be reduced or avoided).

[0062] Furthermore, when the vehicle 10 is subjected to a frontal collision, the inflator is operated 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, the tear line formed on the door trim of the side door is ruptured by the inflation pressure of the airbag 62, and the airbag 62 is inflated and deployed toward at least the head and chest of the occupant P.

[0063] Here, the top plate 40 of the table 30 has slid forward due to the inertial force during the head-on 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 on the vehicle seat 12.

[0064] In particular, the airbag 62 is mounted on the side door, so it can be rapidly and appropriately inflated and deployed in the space expanded by the front sliding of the roof panel 40. In other words, the airbag 62 can be rapidly and appropriately inflated and deployed in the front of at least the head and chest of the occupant P without interfering with the roof panel 40 (without being hindered from inflating and deploying by the roof panel 40).

[0065] Thus, the airbag 62 can effectively block the load from the occupant P who moves forward due to the inertial force generated by the impact during the frontal collision of the vehicle 10. In addition, since the airbag 62 is compressed and deformed, not only the head of the occupant P but also the chest is restrained, the occurrence of brain damage due to centrifugal force can be suppressed or prevented without further flexing the neck of the occupant P.

[0066] Thus, according to the first embodiment, even if the top plate 40 of the table 30 provided on the floor 22 is arranged in front of the occupant P who is normally seated on the vehicle seat 12, the head of the occupant P who moves by inertia can be prevented from hitting the top plate 40 in the event of a head-on collision of the vehicle 10, and at least the head and chest of the occupant P can be effectively and appropriately restrained by the airbag 62.

[0067] In addition, since the top plate 40 is configured to slide forward due to inertial force, the structure is simplified compared to a structure that slides by an electric structure, for example. In addition, since the table 30 is provided with the front plate 38, the top plate 40 is restricted from sliding forward by more than a predetermined amount. Figure 2B As shown, the top plate 40 sliding forward can be prevented from hitting the occupant P sitting on the vehicle seat 12F on the opposite side of the vehicle seat 12 .

[0068] Furthermore, the top plate 40 that has slid forward is prevented from sliding backward due to the reaction force by the preventing mechanism 50 (stopper portion 52) provided in the table 30. Therefore, the following undesirable phenomenon can be prevented from occurring, that is, in the late stage of a frontal collision of the vehicle 10 to the extent that the airbag 62 is not inflated and deployed, the top plate 40 that has slid forward slides backward due to the reaction force and the head of the occupant P hits the top plate 40.

[0069] <Second embodiment>

[0070] The second embodiment will now be described. The same reference numerals are used for the same parts as those of the first embodiment, and detailed descriptions thereof (including common functions) will be omitted as appropriate.

[0071] like Figure 5As shown, in this second embodiment, the difference from the above-mentioned first embodiment is only the following content, namely: 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, a pair of tension coil springs 46 as biasing members for biasing the top plate 40 toward the front side are arranged in a manner spaced apart on the left and right; on the rear side of the inner surface (upper surface) of the base plate 34, a pair of protrusions 48 for preventing the top plate 40 from sliding toward the front side are erected in a manner spaced apart on the left and right.

[0072] The protrusion 48 is formed into a flat plate shape by, for example, a resin material so as to be cut (broken) by the top panel 40 that is about to slide forward due to the inertial force during a frontal collision of the vehicle 10 to the extent that the airbag 62 is deployed. That is, since the input load from the top panel 40 to the protrusion 48 is determined by the weight of the top panel 40 and the acceleration during a frontal collision of the vehicle 10, the weight of the top panel 40 and the shape and strength of the protrusion 48 are set (adjusted) so as to be broken by the input load to the extent that the airbag 62 is deployed (so as not to be broken by the input load to the extent that the airbag 62 is not deployed).

[0073] The urging force of the tension coil spring 46 is such that the top plate 40 with the protrusion 48 cut off (broken) can slide reliably forward to assist the sliding caused by the inertia force of the top plate 40. Therefore, the protrusion 48 is not broken by the top plate 40 pulled forward by the urging force of the tension coil spring 46. The tension coil spring 46 is an example of a mechanical mechanism.

[0074] According to the second embodiment configured as such, since the top plate 40 of the table 30 is configured as described above, when the vehicle 10 is hit head-on, the top plate 40 cuts off the protrusion 48 due to its inertia force and is pulled by the tension coil spring 46 to slide forward, the structure is simplified compared to a structure in which the top plate 40 slides forward by, for example, an electric mechanism. In addition, the shape of the protrusion 48 is not limited to the flat plate shape shown in the figure, and it can be a shape that is easily cut off by the top plate 40 that is about to slide forward due to the above-mentioned inertia force.

[0075] <Third Embodiment>

[0076] The third embodiment will now be described. The same reference numerals are used for the same parts as those of the first embodiment, and detailed descriptions thereof (including common functions) will be omitted as appropriate.

[0077] like Fig. 6A as well as Figure 6BAs shown in the third embodiment, the only difference from the first embodiment is that, in the event of a frontal collision of the vehicle 10, the top panel 40 is forcibly slid forward by a known pretensioner mechanism 56 as an example of a mechanical mechanism. Specifically, one end of a wire 58 is attached to the front surface 40F of the top panel 40, and the other end of the wire 58 is connected to the pretensioner mechanism 56.

[0078] The pretensioner mechanism 56 includes, for example, a gas generator that is activated when the vehicle 10 is subjected to a frontal collision, and a pulling mechanism that instantly pulls the wire 58 when the gas generator is activated. As for the pulling mechanism, for example, a structure including a rack and a pinion gear may be considered.

[0079] That is, the other end of the wire 58 is attached to the outer peripheral surface of the winding drum, and the winding drum is rotated by the rotation of the pinion gear. In addition, the rack meshing with the pinion gear is instantly protruded by the operation of the gas generator.

[0080] According to the third embodiment configured as above, when the vehicle 10 is in a head-on collision, the gas generator operates to instantly rotate the take-up reel via the rack and pinion, so that the wire 58 can be instantly taken up and pulled, and the top plate 40 can be instantly and forcibly slid forward.

[0081] Additionally, the pretensioner mechanism 56 may be configured as follows: Fig. 6A As shown in the figure, it is set inside the support 28 and the top plate 40 is slid forward by pulling the wire 58 downward. Figure 6B As shown, the top plate 40 is provided inside the front plate 38 and is configured to slide forward by pulling the wire 58 to either the left or right side (the left side in the figure).

[0082] When the pretensioner mechanism 56 is disposed inside the support column 28, the passage 28A and the hole portion 34A through which the wire 58 passes are formed in the support column 28 and the bottom plate 34, respectively, in a manner communicating with each other. Furthermore, when the pretensioner mechanism 56 is disposed inside the front plate 38, the front plate 38 is formed thick, and the passage 38A through which the wire 58 passes is formed in the front plate 38.

[0083] In addition, the control device in the third embodiment is electrically connected to the camera and is configured to be able to predict (foresee) the inevitability of a frontal collision of the vehicle 10. That is, the control device according to the third embodiment operates the inflator and the pretensioner mechanism 56 based on information from the collision sensor and the camera, not only when a frontal collision of the vehicle 10 is detected, but also when a frontal collision of the vehicle 10 is predicted. In addition, when a frontal collision of the vehicle 10 is predicted, it is also referred to as "when a frontal collision occurs."

[0084] <Fourth embodiment>

[0085] In addition, about the parts equivalent to the said 1st embodiment to 3rd embodiment, the same code|symbol is attached|subjected, and the detailed description (including common functions) is abbreviate|omitted suitably.

[0086] like Fig. 7A as well as Figure 7B As shown, in the fourth embodiment, the table 30 is different from the first to third embodiments described above only in that the table 30 is integrally provided with the vehicle seat 12 which is set not to slide in the front-rear direction. Specifically, the support column 28 of the table 30 is provided upright in front of the side portion 15 of the vehicle seat 12, for example, provided outside the seat cushion 14 in the seat width direction.

[0087] According to the fourth embodiment having such a structure, when the vehicle 10 is in a head-on collision, the top panel 40 protruding toward the occupant P side slides forward, thereby forming a space in front of at least the head and chest of the occupant P, and the airbag 62 that is inflated and deployed from the side door can be arranged in front of at least the head and chest of the occupant P.

[0088] <Fifth embodiment>

[0089] Finally, the fifth embodiment will be described. In addition, the same reference numerals are given to the same parts as those of the fourth embodiment, and detailed descriptions thereof (including common functions) are appropriately omitted.

[0090] like Fig. 8A as well as Figure 8B As shown, in the fifth embodiment, the airbag device 60 is different from the fourth embodiment described above 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 able to slide in the front-rear direction. Specifically, the airbag device 60 is built into the rear side of the bottom plate 34 or the fixed top plate 36.

[0091] According to the fifth embodiment having such a structure, when the vehicle 10 is subjected to a head-on collision, the top plate 40 protruding toward the occupant P slides toward the front side, thereby forming a space in front of at least the head and chest of the occupant P, and the airbag 62 inflated and deployed from the table body 32 can be arranged in front of at least the head and chest of the occupant P.

[0092] In addition, since the airbag device 60 is mounted on the table body 32 (bottom plate 34 or fixed top plate 36) of the table 30 that slides in the front-to-rear direction integrally with the vehicle seat 12, the airbag 62 can be quickly and appropriately expanded and deployed into the space expanded by the top plate 40 sliding forward, regardless of the front-to-rear position of the vehicle seat 12.

[0093] The occupant protection device 20 of the vehicle 10 with the table 30 according to the present embodiment has been described above based on the drawings, but the occupant protection device 20 of the vehicle 10 with the table 30 according to the present embodiment is not limited to the contents shown in the drawings, and the design can be appropriately changed without departing from the scope of the present disclosure. For example, the mechanical mechanism is not limited to the tension coil spring 46 or the pretensioner mechanism 56.

[0094] In addition, the top plate 40 is not limited to a structure in which a plurality of rollers 42 provided on the side surface 40S roll and slide on the inner surface 35S of the side plate 35 of the table body 32, but may also be provided with a structure in which an engaging portion provided on the side surface 40S of the top plate 40 is engaged and slides in a slidable manner on, for example, a track provided on the inner surface 35S of the side plate 35.

[0095] In addition, the airbag device 60 (airbag 62) is not limited to the structure in which it is mounted on the side door or the table body 32 of the table 30, and can also be mounted on the vehicle seat 12, the roof of the vehicle compartment, the center console, or the seat belt 26 (lap belt). In any case, since the airbag 62 expands and deploys into the space expanded by the front sliding of the top plate 40, it will become as shown in the figure. Figure 2B , Figure 7B As shown, the airbag 62 has a shape as shown. In this way, in the present embodiment, there are many options for the location where the airbag device 60 is mounted, and the degree of freedom in design is also high.

[0096] In addition, in at least the fourth embodiment among the fourth embodiment and the fifth embodiment, the front plate 38 may not be provided in the table body 32. In particular, when the table 30 is provided on the vehicle seat 12 which is configured in a non-sliding manner, the table body 32 is sufficiently far away from the occupant P sitting on the vehicle seat 12F on the opposite side of the vehicle seat 12. Therefore, even if the front plate 38 is not provided in the table body 32, the top plate 40 which slides toward the front side does not hit the occupant P sitting on the vehicle seat 12F.
