  However, all of the conventional occupant protection devices are configured to protect both occupants seated in two seats by inflating one airbag, and from the occupant's thigh by the airbag. It was the structure which protected over the head. For this reason, in the conventional occupant protection device, the airbag has a seating surface that has a large width so as to fill a gap between the occupants seated in each seat and covers the side of the occupant widely. Because it has a structure that expands from the top to the top of the backrest, it has a large capacity, and a large output is required as an inflator for inflating the airbag. There was room for improvement.

  An object of the present invention is to solve the above-described problems, and to provide an occupant protection device that can reduce weight while suppressing an increase in manufacturing cost and can accurately protect an occupant. To do.

The occupant protection device according to the present invention is mounted on a vehicle that is arranged side by side so that two seats are connected, with a center console interposed therebetween, and from one side in the direction in which the seats are arranged side by side. An occupant protection device configured to protect a remote occupant seated on a remote seat far from the impact force acting side when the impact force is applied,
A console main body disposed on the side of the seat in the remote seat, and an extending portion arranged to extend from the console main body on the back seat side of the remote seat, from the seat to the backrest A center console configured to be placed on the side,
The extension portion is folded and stored near the side portion on the separation side seat side, and is expanded and inflated by flowing an expansion gas into the inside so as to cover the impact force acting side of the separation side occupant. An airbag,
It is set as the composition provided with,
An occupant restraint surface that can be received from the chest of the remote occupant to the head when the inflation is completed, and a support surface that is supported by the surface of the extension when the occupant restraint surface receives the remote occupant. It is set as the structure provided.

  In the occupant protection device of the present invention, the airbag that is folded and stored in the vicinity of the side portion of the extension portion of the center console is separated from the chest of the remote occupant seated on the remote seat by the occupant restraint surface when the inflation is completed. The airbag is configured to be received and restrained over the head, and the airbag is configured to support the support surface by the extending portion of the center console when the separated occupant is received. That is, in the occupant protection device of the present invention, since the airbag that has received the separation side occupant by the occupant restraint surface is supported by the extension portion of the center console at the site of the support surface, It can be restrained accurately by the occupant restraint surface. Therefore, even if the volume is set small so that the airbag can cover only the head from the chest, the remote occupant can be protected smoothly. As a result, in the occupant protection device of the present invention, the volume of the airbag can be reduced, and the inflator that supplies the inflation gas to the airbag can also use a small output.

  Therefore, in the occupant protection device of the present invention, an increase in manufacturing cost can be suppressed, the weight can be reduced, and the occupant can be protected accurately.

  Further, in the occupant protection device of the present invention, if the airbag is arranged as two parts, that is, the separation side seat side and the close side seat side close to the impact force acting side, the impact is applied from the opposite direction side. When a force is applied, the proximity occupant seated in the proximity seat (the side away from the impact force application side) can be protected smoothly, which is preferable.

  Specifically, when the impact force is applied, among the airbags, only the separated airbag stored in the separated seat side may be operated so as to be inflated. It is good also as a structure which act | operates so that both of an airbag may be inflated.

  Further, in the occupant protection device having the above-described configuration, the airbag is configured as a substantially triangular prism shape so that the inflation completion shape is substantially along the axial direction in the vertical direction and substantially along the surface of the extending portion, and the direction around the axis If one of the three side surfaces arranged substantially along is configured as an occupant restraint surface and the other one is configured as a support surface, after receiving the separated occupant by the occupant restraint surface, If the airbag moves toward the extending portion, the airbag is supported by the extending portion by bringing a supporting surface formed from a side surface adjacent to the side surface into contact with the extending portion. It becomes. Since this support surface is composed of one of the three side surfaces, it will be widely supported by the extension portion on the width direction side of the extension portion when contacting the extension portion, and the extension portion Therefore, it will be supported stably. Further, in this airbag, when the inflation is completed, the occupant restraint surface and the support surface are arranged so as to expand from the crossing end side to the distal end side when viewed from the cross section of the airbag when the inflation is completed. In other words, since the airbag is inflated thickly in the region on the front end side of the occupant restraint surface and the support surface, the cushioning action is secured by this thickly inflated region. Thus, the occupant on the remote side can be accurately received. Therefore, even if the volume is reduced, by supporting the thickly inflated region on the extending portion through the support surface in a wide range on the width direction side, the separated occupant can be stabilized by the occupant restraint surface. It is preferable that the air bag can be accurately received, the airbag can be configured more compactly, and the remote occupant can be protected smoothly.

  Furthermore, in the occupant protection device configured as described above, if at least one of the console main body or the extending portion is configured to protrude from the seating surface or the backrest surface of the seat, the occupant is located at the site of the center console. The seating can be prevented, and the occupant seated at an appropriate position can be appropriately protected by the airbag that has been inflated, which is preferable.

In the case of the embodiment, the airbag covers 20L and 20R are made of a soft synthetic resin such as a polyolefin-based thermoplastic elastomer (TPO). In the embodiment, the cushions 8L and 8R of the backrest portions 7L and 7R are arranged in contact with the side of the airbag covers 20L and 20R (outward in the left-right direction), but the cushions 8L and 8R are elastic. Therefore, when the inflators 22L and 22R are operated, the airbags 25L and 25R are compressed by the airbags 25L and 25R that are inflated by flowing the inflation gas into the interiors. The airbag covers 20L and 20R are pushed open while being pressed so as to compress the 8L and 8R, and the airbag covers 20L and 20R are pushed forward to smoothly protrude forward. The airbag covers 20L and 20R are interior materials arranged on the left and right sides of the design surface portion 16 so that the front end 20b side is exposed in the vehicle interior (see FIGS. 1, 6 and 7). Not only the housing parts of 25L and 25R but also the entire upper and lower (front and rear) portions of the extending portion 15 are arranged.

  In the embodiment, the inflators 22L and 22R are arranged one by one at positions on the left and right sides of the extending portion 15, respectively, and can supply inflation gas to the airbags 25L and 25R, respectively. Moreover, it is connected to each airbag 25L, 25R. Specifically, the inflators 22L and 22R are cylinder types whose outer shapes are cylindrical, and the rear end side of the attachment wall portion 17 in the extended portion 15 (the rear end side of the left side wall portion 17a and the right side wall portion 17b). The bracket extends from the body 1 side by using a retainer (not shown), with the axial direction substantially aligned with the backrest portions 7L and 7R (design surface portion 16) (see FIG. 2). 3 is fixed. In the case of the embodiment, the inflators 22L and 22R are electrically connected to an airbag operation circuit (not shown) so as to be separately operable. In the occupant protection device S of the embodiment, when the vehicle V undergoes a side collision (receives an impact force) from the left side during traveling, only the inflator 22R disposed on the right seat 5R (separate side seat) side operates. Will be. The inflator 22L disposed on the left seat 5L side is configured to be activated when an impact force acts on the vehicle V from the right side, and does not operate when the inflator 22R disposed on the right seat 5R side is activated. So that the operation is controlled.

  Each of the airbags 25L and 25R is configured as a bag formed from a flexible sheet body that inflates by inflating the inflation gas discharged from each of the inflators 22L and 22R. In the embodiment, as described above, when the inflator 22R disposed on the right side is activated, the inflator 22L disposed on the left side is not activated, and the airbags 25L and 25R are configured to be inflated simultaneously. Not. In the embodiment, the airbag 25R housed on the right seat 5R side will be described in detail by way of example, but the airbag 25L housed on the left seat 5L side is also inflated, although detailed illustration and description are omitted. Except for the completed shape being bilaterally symmetric, the configuration is the same as that of the airbag 25R housed on the right seat 5R side.

  The airbag 25R is configured to be able to protect from the chest MB of the remote occupant MP to the head MH when the inflation is completed. As shown in FIGS. The configuration is such that the occupant MP can be covered from the chest MB to the head MH of the separated occupant MP seated on the right seat 5R as a seat. In addition, the airbag 25R has an inflated shape (specifically, an inflated shape excluding the attachment portion 29 described later. In other words, the airbag 25R protrudes from the backrest portion 7R and the extending portion 15 and expands in a free space. (Completed shape) is configured as a substantially triangular prism shape so that the axial direction is substantially along the vertical direction and substantially along the surface (design surface portion 16) of the extending portion 15 (two-dot chain line in FIG. 1 and FIG. 4). reference). Specifically, as shown in FIG. 4, the airbag 25 </ b> R has a substantially triangular cylindrical peripheral wall in which the right side wall 26 a located on the right side (separate side occupant MP side) is arranged along the front-rear direction when the inflation is completed. It is made into the substantially triangular prism shape comprised including the part 26 and the ceiling wall part 27 and the bottom wall part 28 which each block | close the upper end side and lower end side of the surrounding wall part 26 (refer FIG. 6, 7). In the peripheral wall portion 26, a front side wall 26b and a rear side wall 26c are juxtaposed on the left and right sides of the right side wall 26a in the front-rear direction side so as to connect the left end side. More specifically, the airbag 25R of the embodiment is configured such that the inflation completion shape excluding the attachment portion 29 is a substantially triangular prism shape in which the ceiling wall portion 27 and the bottom wall portion 28 are substantially equilateral triangle shapes.

  In the airbag 25R according to the embodiment, of the three side surfaces (side walls) disposed along the direction of the axis in the peripheral wall portion 26, the right side wall 26a disposed substantially along the front-rear direction on the right side when the inflation is completed. However, the occupant restraint surface 30 that protects the separation-side occupant MP is configured, and the rear side wall 26c that is disposed to be inclined with respect to the front-rear direction on the rear side (the extended portion 15 side) is separated by the occupant restraint surface 30. When the side occupant MP is received, the support surface 31 supported by the surface of the extended portion 15 (design surface portion 16) is configured. When the separation-side occupant MP is received by the occupant restraint surface 30, the airbag 25R is pushed leftward by the separation-side occupant MP, and the rear end 30b of the occupant restraint surface 30 is indicated by a two-dot chain line in FIG. The front surface 30a of the occupant restraint surface 30 is rotated so that the front end 30a side is directed to the left about the side portion. At this time, the support surface 31 constituted by the rear side wall 26c is formed on the surface of the extended portion 15 ( In contact with the design surface portion 16), the airbag 25R is supported by the surface of the extended portion 15 (design surface portion 16), and the airbag 25R is restricted from further rotational movement. Further, in the airbag 25R of the embodiment, the rear end 30b side of the occupant restraint surface 30 is configured such that the portion of the attachment portion 29 connected to the inflator 22R is coupled to the bracket 3 on the body 1 side together with the inflator 22R. For this reason, the support by the support surface 31 can be stabilized without moving forward even during rotational movement. Furthermore, in the airbag 25R of the embodiment, the ceiling wall portion 27 and the bottom wall portion 28 are configured to have a substantially equilateral triangle shape. In other words, the occupant restraint surface 30 configured by the right side wall 26a and the rear side wall The support surface 31 composed of 26c is set to have substantially the same size (area). The occupant restraint surface 30 has a width dimension on the front-rear direction side and a length dimension on the vertical direction side when the inflation of the airbag 25R is completed, when the occupant restraint surface 30 receives the occupant MP from the occupant MP on the side of the occupant MP. The area up to MH is set so that it can be restrained accurately. Specifically, the occupant restraint surface 30 has a front end side (front end 30a side) on the left side of the separated occupant MP seated on the right seat 5R as shown in FIG. 4 when the inflation of the airbag 25R is completed. The configuration is arranged such that the upper end 30c side is positioned slightly above the center of the upper and lower sides of the head MH of the separation side occupant MP while projecting forward from the chest MB of the separation side occupant MP. Further, the support surface 31 (rear side wall 26c) set to be approximately the same size as the occupant restraint surface 30 is formed on the surface of the extended portion 15 (the design surface portion 16 of the design surface portion 16) when the occupant restraint surface 30 receives the separation side occupant MP. The airbag 25R in a state of receiving the separation side occupant MP when being in contact with the surface 16a) is configured to be able to be accurately supported by the surface of the extended portion 15 (design surface portion 16). In the airbag 25R of the embodiment, as shown in FIG. 5, the support surface 31 (rear side wall 26c) is disposed on the left end 31a side in the inflated state in which the occupant restraint surface 30 is disposed substantially along the front-rear direction. When the extended portion 15 (design surface portion 16) is positioned slightly to the right of the left edge and comes into contact with the surface of the extended portion 15 (design surface portion 16), the left end 31a side from the extended portion 15 Also, it is configured to protrude to the left and to be supported over substantially the entire left and right sides of the extended portion 15 (design surface portion 16).

  In the occupant protection device S of the embodiment, at the time of a side collision in which a collision object (not shown) collides from the left side LW of the vehicle V, the right side RW separated from the collision side (impact force acting side) receives an actuation signal from the airbag actuation circuit. The inflator 22R disposed on the right side RW is activated, and the airbag 25R disposed on the right side RW is inflated by inflating the inflation gas into the interior, pushing the airbag cover 20R open, It protrudes forward from the gap formed between the extended portion 15 and the backrest portion 7R of the right seat 5R, and as shown in FIGS. 4 to 7, the left side from the chest MB of the remote occupant MP to the head MH Expansion will be completed so that it may cover.

  In the occupant protection device S of the embodiment, the airbag 25R that is folded and housed near the side of the extending portion 15 (in the embodiment, the right side surface) of the center console 11 is restrained when the inflation is completed. The surface 30 is configured to receive and restrain from the chest MB of the remote occupant MP seated on the right side seat 5R as the remote side seat to the head MH, and the airbag 25R is received by the remote occupant MP. At the time of stopping, the support surface 31 is supported by the extended portion 15 of the center console 11. That is, in the occupant protection device S according to the embodiment, the airbag 25R that receives the separation-side occupant MP by the occupant restraint surface 30 is supported by the extended portion 15 (design surface portion 16) of the center console 11 at the portion of the support surface 31. Therefore, the occupant restraint surface 30 can be restrained accurately by the occupant restraint surface 30. Therefore, even if the volume is set to be small so that the airbag 25R can cover only the head MH from the chest MB, the separation-side occupant MP can be protected smoothly. As a result, in the occupant protection device S of the embodiment, the volume of the airbag 25R can be reduced, and the inflator 22R that supplies the inflation gas to the airbag 25R can also use a small output.

  Therefore, in the occupant protection device S of the embodiment, an increase in manufacturing cost can be suppressed, the weight can be reduced, and the occupant MP can be protected accurately.

  In the occupant protection device S according to the embodiment, two airbags 25L and 25R, that is, the right side seat 5R side that is the separation side seat and the left side seat 5L side that is the close side seat close to the impact force acting side, In the embodiment, when the impact force is applied from the right side RW on the opposite direction side, the left side seat 5L that is the close side seat (the direction side away from the impact force application side) is provided. The passengers seated in) can also be protected smoothly.

  Furthermore, in the occupant protection device S of the embodiment, the airbag 25R has a substantially triangular prism that allows the inflation completion shape to be substantially along the axial direction in the vertical direction and substantially along the surface of the extension portion 15 (design surface portion 16). The right side wall 26a that is one of the three side surfaces of the peripheral wall portion 26 that is configured as a shape and is arranged substantially along the axis is used as an occupant restraint surface 30, and the rear side wall 26c that is the other side is supported. The surface 31 is configured. That is, in the airbag 25R of the embodiment, the occupant restraint surface 30 and the support surface 31 are configured by two adjacent side surfaces (the right side wall 26a and the rear side wall 26c) of the peripheral wall portion 26 having a substantially triangular cylindrical shape. Therefore, if the airbag 25R moves toward the extended portion 15 after the separation-side occupant MP is received by the occupant restraint surface 30, the airbag 25R is supported by the support surface 31 adjacent to the occupant restraint surface 30. Is brought into contact with the extended portion 15 (design surface portion 16) to be supported by the extended portion 15. Since this support surface 31 is composed of one of the three side surfaces of the peripheral wall portion 26, when contacting the extension portion 15, the width direction side of the extension portion 15 (in the case of the embodiment, the left-right direction side). Therefore, the extended portion 15 is widely supported, and is stably supported by the extended portion 15. Further, in the airbag 25R, when the inflation is completed, the occupant restraint surface 30 and the support surface 31 intersect with each other as viewed from the cross section of the airbag 25R when the inflation is completed (the rear of the occupant restraint surface 30). In other words, the airbag 25R is inflated thickly in the region of the front end side of the occupant restraint surface 30 and the support surface 31. Therefore, this thickly inflated region can secure the cushion action and accurately receive the occupant MP on the separated side. For this reason, even if the volume is reduced, the region that is thickly inflated is supported by the extended portion 15 in a wide range on the width direction side (left and right direction side) via the support surface 31, so that the separation side occupant MP Can be stably and accurately received by the occupant restraint surface 30, the airbag 25R can be configured more compactly, and the separated occupant MP can be protected smoothly. As a result, for example, the airbag 25R can be configured more compactly compared to the case where the inflation completion shape is spherical or the like, and the separation-side occupant MP can be protected smoothly.

  In particular, in the occupant protection device S of the embodiment, each airbag 25L, 25R is connected to another inflator 22L, 22R, and when the impact force is applied from the left side, the right inflator is separated from the impact force application side. Only 22R is operated and only the airbag 25R disposed on the right seat 5R side is inflated. In other words, in the occupant protection device S of the embodiment, the inflators 22L and 22R are not operated at the same time, and the airbags 25L and 25R are not inflated at the same time. Therefore, the airbag 25R is connected to the left airbag 25L. It is not necessary to consider the interference with the above, and a wide expansion area can be secured. In the embodiment, the airbag 25R is configured to inflate in a substantially triangular prism shape in which the ceiling wall portion 27 and the bottom wall portion 28 are substantially equilateral triangle shapes. Therefore, in the airbag 25R of the embodiment, the size (surface area) of the support surface 31 is substantially the same as the size (surface area) of the occupant restraint surface 30, and the region supported by the extending portion 15 is wide. Can be secured. In the embodiment, the support surface 31 is configured to be supported over the entire region on the left and right sides of the extension portion 15 (design surface portion 16) when in contact with the extension portion 15 (design surface portion 16). Further, the separation distance between the front end (front end 30a) side of the occupant restraint surface 30 and the front end (left end 31a) side of the support surface 31 is also the direction side along the occupant restraint surface 30 or the ceiling wall portion 27 of the support surface 31. Since the width dimension of the airbag 25R can be secured to be large and the airbag 25R can be inflated thickly in this region.

  In the occupant protection device S of the present invention, in the region between the left seat 5L and the right seat 5R, the region from the chest to the head of the occupant seated in each seat 5L, 5R, in more detail, this is wide. An area that is a substantially rectangular parallelepiped space PS (a hatched area in FIGS. 8A and 8B) that is wide in the front-rear and left-right directions so as to extend forward from the extended portion 15 to a position ahead of the chest. From the viewpoint of accurate occupant protection, it is desirable to inflate the airbag so that In the embodiment, each of the airbags 25L and 25R is configured not to be inflated at the same time, and the inflated completion shape is a substantially triangular prism shape, and the airbag 25R (25L) is restrained by an occupant when the inflating is completed. In the state where the surface 30 is configured to cover substantially the entire surface on the occupant side in the space PS and the support surface is supported by the extended portion 15 after the separation side occupant is received, the support surface 31 is The rear surface of the space PS (the surface on the extending portion 15) is configured to cover almost the entire surface. Therefore, in the embodiment, the airbag 25R (25L) is configured so as to accurately close a region necessary for occupant protection and does not expand to a region that does not affect occupant protection. As a minimum volume, the airbag 25R (25L) can be made compact, and an occupant can be protected accurately and stably. If such a point is not taken into account, even when only one airbag is configured to be inflated, the inflation completion shape of the airbag is not a substantially triangular prism shape. You may use what was made into the substantially rectangular parallelepiped shape etc. which close.

  In the occupant protection device S of the embodiment, as described above, the airbags 25L and 25R are connected to the inflators 22L and 22R, respectively, and only one of them is inflated. It is good also as a structure which expands a bag simultaneously at the time of the effect | action of the impact force from a side. When the airbag is configured to be inflated at the same time, the space PS is filled with two airbags arranged on the left and right sides when the inflation is completed.

  The airbags 35L and 35R shown in FIG. 9 have a shape that allows the inflation completion shapes to be fitted to each other so as to bisect the space PS. Specifically, in FIG. 9, the airbags 35L and 35R are configured so that the axial direction is substantially along the front-rear direction so as to bisect the space PS in the vertical direction, and the bottom surface 35b is placed on the hypotenuse side. It is configured as a substantially triangular prism shape that is a substantially right-angled triangle shape that is adjacent. More specifically, in FIG. 9, the airbag 35 </ b> L disposed on the left side is configured such that the substantially right-angled corner is positioned on the lower side, and the airbag 35 </ b> R disposed on the right side is substantially rectangular. It is comprised so that the corner | angular part of may be located above. In the airbags 35L and 35R having such a configuration, the side surfaces 35a and 35a disposed on the occupant side when the inflation is completed are the occupant restraint surfaces 36L and 36R, respectively, and the extended portion 15 side is provided. The bottom surfaces 35b and 35b are configured as support surfaces 37L and 37R. Therefore, even if it is the structure which completes expansion | swelling at the same time, a separation side passenger | crew can be accurately received by wide passenger | crew restraint surface 36L, 36R, and after reception of a separation side passenger | crew, it is right and left of a substantially right triangle shape. The airbags 35L and 35R can be accurately supported by the surface of the extended portion 15 (design surface portion 16) by the support surfaces 37L and 37R having wide regions. Further, in the airbags 35L and 35R, the thickness in the left-right direction at the completion of the inflation becomes thinner toward the upper end side or the lower end side, but even if the passenger is seated in both seats, the side collision In some cases, only the separated occupant seated in a seat separated from the impact force acting side is protected by an airbag that inflates between the seats, and the other airbag is inflated thickly in a thin region. Therefore, the two side airbags 35L and 35R can protect the occupant on the separated side without any trouble.

  Further, in the case where the two airbags are inflated so that the expansion completion shape is fitted to each other so as to bisect the space PS, as shown in FIG. 39R may be configured as an inverted L shape when viewed from the front side of the vehicle so that the expansion completion shape of 39R is point-symmetrical when viewed from the front side of the vehicle. More specifically, in FIG. 10, the airbag 39 </ b> L disposed on the left side is configured to position the intersecting portion on the lower side, and the airbag 39 </ b> R disposed on the right side positions the intersecting portion on the upper side. It is configured as follows. In the airbags 39L and 39R having such a configuration, each of the airbags 39L and 39R has a substantially inverted L shape with the side surfaces 39a disposed on the occupant side when the inflation is completed as occupant restraint surfaces 40L and 40R. The bottom surface 39b on the extended portion 15 side is configured as the support surfaces 41L and 41R. Therefore, even if it is the structure which completes expansion | swelling simultaneously, a separation side passenger | crew can be accurately received by wide passenger | crew restraint surface 40L, 40R, and after reception of a separation side passenger | crew, it is left and right as a substantially reverse L shape. The airbags 39L and 39R can be accurately supported by the surface of the extended portion 15 (design surface portion 16) by the support surfaces 41L and 41R having wide areas. Each airbag 39L, 39R has a thin area in the left-right direction at the time of completion of inflation. Like the airbags 35L, 35R, the other area has a thin area. Since the airbag is inflated thickly, the two occupants 39L and 39R can protect the occupant on the remote side without hindrance.

  If it is not considered to secure a wide support surface on the left and right, the airbag 43L, 43R arranged on the left and right, as shown in FIG. A flat rectangular parallelepiped extending in the front-rear and up-down directions may be arranged side by side in the left-right direction. In each of the airbags 43L and 43R having such a configuration, although the wide occupant restraint surfaces 44L and 44R can be secured by using the side surfaces 43a disposed on the occupant side when the inflation is completed as the occupant restraint surfaces 44L and 44R, the extended portion 15 Since the support surfaces 45L and 45R including the bottom surface 43b on the side are configured with a constant width dimension in the left-right direction over the entire upper and lower regions, and are supported in a half region of the extending portion 15, the above-described airbags 35L, 35R, Compared to 39L and 39R, it is difficult to ensure stable support by the support surfaces 45L and 45R. However, when the remote occupant is received, the airbag that receives and moves the remote occupant can also be supported by the other airbag, so the two air bags 43L and 43R can safely protect the remote occupant. can do.

  Although not shown in the airbags 35L, 35R, 39L, 39R, 43L, and 43R shown in FIGS. 9 to 11, the occupant restraint surfaces 36L, 36R, 40L, 40R, 44L, and 44R are similar to the airbag 25R. Since the rear end side is a portion of the attachment portion and is connected to the bracket on the body side together with the inflator, it does not move forward even during rotational movement, and the support surfaces 37L, 37R, 41L, 41R, 45L , 45R can be supported stably.

  When two airbags are configured to be inflated at the same time, each airbag may be connected to another inflator, and the two airbags may be configured to be inflated by one inflator. May be.

  Further, in the occupant protection device S of the embodiment, since the entire console body is configured to protrude from the seating surface of the seat portion, it is possible to prevent the occupant from sitting on the center console, The occupant seated in the position can be appropriately protected by the airbag that has been inflated. The console main body may be configured to partially protrude from the seating surface of the seat, or the console main body may be substantially flush with the seating surface and the extended portion may protrude from the backrest. Furthermore, it is good also as a structure which makes both a console main body and an extending part protrude from a seat part and a backrest part.

  In the embodiment, the rear seat of the vehicle has been described as an example. However, the occupant protection device of the present invention is not limited to being mounted on the rear seat of the vehicle. For example, the occupant protection device is juxtaposed along the front-rear direction. The present invention can also be applied to a vehicle having a seat.
