Description

  The present invention is mounted on a vehicle in which seats are arranged side by side in the left-right direction, and protects a remote-side occupant seated on a remote-side seat far from the collision side at the time of a side collision from one side in the left-right direction during traveling. It relates to a possible occupant protection device.

  Conventionally, as an occupant protection device, airbags that are inflated while projecting forward are disposed on the left and right sides of two seats arranged side by side in the left-right direction so as to cover the left and right sides of the seat, respectively. There was a thing of the made composition (for example, refer to patent documents 1 and 2).

  In the occupant protection devices described in Patent Documents 1 and 2, in the event of a side collision from one side in the left-right direction during travel, the occupant seated in the seat by inflating the collision-side airbag disposed on the collision side in each seat It was the composition which protects. When the vehicle moves sideways from one side in the left-right direction while moving forward while traveling, the vehicle moves forward diagonally away from the collision side, and the occupant seated in the seat faces the collision side. The inertial force that moves diagonally forward is received. Usually, the occupant wears a three-point restraint type seat belt and sits on the seat, but in the case of a three-point restraint type seat belt, the occupant positions the upper end on the vehicle exterior (window side) and The shoulder belt that is obliquely positioned so as to position the lower end on the inside restrains the shoulder located on the outside of the vehicle from the vicinity of the waist on the inside of the vehicle. A remote occupant seated in a remote seat far from the collision side is restrained from the shoulder on the side far from the collision side to the vicinity of the waist on the collision side by the shoulder belt of the three-point restraint seat belt. When the inertial force at the time of a side collision is received, the shoulder occupant may not be prevented from moving diagonally forward toward the collision side by the shoulder belt.

  In the occupant protection devices described in Patent Documents 1 and 2, the airbag is inflated while projecting forward so as to cover the collision side of the seat, in other words, the airbag is free on the front end side. Since the expansion is completed as an end, the front end side when the expansion is completed is likely to shake to the left and right, and the inertial force is restrained so that the occupant on the remote side moving diagonally forward in the vehicle interior toward the collision side is accurately restrained. There was a problem.

Also, as an occupant protection device, a side airbag that inflates so as to cover the vehicle exterior side of the seat during operation, and a front airbag that is folded and stored in front of the seat and inflates while projecting toward the vehicle rear side during operation. (For example, refer to Patent Document 3).
Japanese Patent Laid-Open No. 7-267037 Special table 2006-524161 US Patent Publication No. 2005/0156411

  However, even in the occupant protection device described in Patent Document 3, when the seat on which the occupant protection device is mounted is a remote side seat far from the collision side, the remote side occupant seated on the remote side seat is In response to the force, it will move to the side away from the side airbag, and the remote occupant moves diagonally forward in the vehicle interior away from the front airbag. There was a problem in accurately restraining the occupant on the remote side.

  The present invention solves the above-mentioned problem, and at the time of a side collision from one side in the left-right direction during traveling, an occupant protection device that can accurately protect a remote occupant seated on a remote seat far from the collision side The purpose is to provide.

The occupant protection device according to the present invention is mounted on a vehicle in which seats are arranged side by side in the left-right direction, and is seated on a separate seat far from the collision side at the time of a side collision from one side in the left-right direction during traveling. An occupant protection device capable of protecting a remote occupant,
Corresponding to the movement of the separated occupant in the direction from the lateral side to the diagonally forward side on the collision side at the time of the collision, during operation, between the adjacent seat and the separated seat close to the collision side during operation A first receiving body disposed in a space extending from the collision side of the separated occupant to the front side, and a second receiving body disposed in front of the near side seat;
The first receiving body can receive the separated occupant at the beginning of movement, or can further guide the moving separated occupant to the second receiving body side, during operation, between the adjacent seat and the separated seat. As a configuration that protrudes from the storage part and is arranged,
The front side in which the second receiving body is able to receive the separation side occupant guided by the first receiving body, and inflates by inflating gas in operation and protrudes rearward from the storage portion in front of the adjacent seat. It is characterized by being configured as an airbag.

  In the occupant protection device according to the present invention, in the case of a side collision from one side in the left-right direction during traveling, the first catch is provided in the space extending from the collision side of the remote occupant to the front side between the close side seat and the remote side seat. A body is arrange | positioned and the 2nd receiving body will be arrange | positioned ahead of the near side seat. That is, in the occupant protection device of the present invention, the first receiving body covers the collision side of the separated occupant seated on the separated seat, and the front side in the moving direction when the separated occupant moves by receiving inertial force. The second receiving body is disposed obliquely forward on the collision side. Therefore, in the occupant protection device according to the present invention, even when the separation-side occupant moves to the lateral side or the diagonally front side on the collision side at the time of a side collision, first, from the collision side of the separation-side occupant to the front side It is possible to receive the occupant on the remote side by the first receiving body arranged so as to extend. In addition, when the separation-side occupant in contact with the first receiving body moves obliquely forward so as to go further toward the collision side, the separation-side occupant is the first receiving body. Therefore, it moves forward while being guided to the second receiving body side. In the occupant protection device of the present invention, since the second receiving body is constituted by a front airbag that inflates with the inflating gas flowing in during operation, the second receiving body is moved forward by the second receiving body. The side occupant can be received with certainty.

  Therefore, in the occupant protection device according to the present invention, in the case of a side collision from one side in the left-right direction during traveling, the first and second receiving bodies are used in two stages to receive a separate seat far from the collision side. It is possible to accurately protect the seated remote occupant.

  Further, in the occupant protection device according to the present invention, the side air is arranged so that the first receiving body is inflated from the storage portion between the close-side seat and the separate-side seat by allowing the inflation gas to flow during operation. When configured as a bag, the cushioning property of the first receiving body is improved, and the occupant on the remote side can be softly restrained, which is preferable.

  Further, in the occupant protection device having the above-described configuration, the rear end side when the operation of the first receiving body is completed is fixed to the vehicle side, and the front end side can be guided to the second receiving body side so that the separated occupant can be guided to the second receiving body side. If the free end that can move in the direction is arranged, the first receiving body that receives the separated occupant is pushed by the separated occupant and moves so that the front end is directed to the left side. Since the side occupant is guided to the second receiving body side, the first receiving body can reliably guide the separated occupant to the second receiving body side, which is preferable.

  Furthermore, in the occupant protection device having the above-described configuration, the support body capable of supporting the second receiving body is configured to protrude from the surrounding storage portion on the collision side when the operation of the second receiving body is completed. preferable.

  In the occupant protection device of the present invention, since the second receiving body is constituted by the front side airbag, it can receive the separation side occupant with good cushioning properties. However, when the separation side occupant receives the separation side occupant, There is a risk of swinging from side to side under the pressing force. However, in the occupant protection device having the above-described configuration, even if the front airbag is swung by receiving the pressing force of the distant occupant, the collision side can be supported by the support body, so that the swing is suppressed. The front side airbag as the second receiving body can accurately receive the separation side occupant while ensuring the cushion effect.

  Furthermore, in the occupant protection device configured as described above, the first receiving body and the second receiving body project the front end of the first receiving body and the rear end of the second receiving body when the operation is completed in the left-right direction of the vehicle. In the state, it is preferable to be arranged so as to overlap.

  In the occupant protection device configured as described above, when the first receiving body is pushed by the moving-side occupant so that the front end side is directed toward the collision side, the front end of the first receiving body is behind the second receiving body. It will contact the end. Therefore, the 1st receiving body can receive the separation side occupant in the state which improved the restraint force of the state where the front end side was supported by the 2nd receiving body. Of course, when the separated occupant in contact with the first receiving body further moves obliquely forward, the first receiving body is released from the contact state with the second receiving body on the front end side. While moving the front end toward the collision side, the separated occupant is guided to the second receiving body side. The separated-side occupant is guided by the side air bag and comes into contact with the edge side away from the collision side at the rear end of the second receiving body, and this second receiving body is caused to collide with the rear end. It will be received by the 2nd receiving body so that it may be greatly dented from the edge side away from the side. As a result, in the occupant protection device having the above-described configuration, the separation-side occupant moving obliquely forward can be received by the first receiving body with increased restraining force, and the separation that could not be received by the first receiving body. Since the side occupant absorbs the kinetic energy by the guide movement of the first receiving body and is then received by the second receiving body, the side occupant accurately receives the separated side occupant by the first receiving body and the second receiving body. Can do.

On the left side, the shielding material 49 made of a flexible sheet material is folded and stored, and during operation, the shielding material 49 protrudes from the storage portion so as to cover the left side of the driver's seat DS. As a configuration to be deployed, the first receiving body may be configured from the shielding material 49. The shielding member 49 constituting the first receiving body is made of a woven fabric made of polyester yarn, polyamide yarn or the like, and can cover the left side of the driver's seat DS when the deployment is completed as shown in FIGS. The upper end 49a is arranged near the upper end of the backrest B, the front end 49b is arranged near the front end of the seat S, and the hypotenuse 49c is arranged on the front edge side. In the case of the form, a plurality of radial creases are made starting from the upper end 49a so that the hypotenuse 49c approaches the rear side 49d arranged along the vertical direction, as shown in parentheses in FIG. It will be folded into a bellows shape. The shielding member 49 is accommodated from the backrest B on the left side of the driver seat DS to the rear side of the seat S so that the upper end 49a, the lower end 49e, and the front end 49b are fixed to the driver seat DS side. (See FIG. 11). The shielding member 49 is connected to the pretensioner 50 disposed near the front end of the seat S via a string-like traction member 51 in the vicinity of the front end 49b that is folded and stored. 50 is operated to retract the traction material 51 to cause the shielding material 49 to protrude from the storage portion, and the shielding material 49 is deployed so as to cover the left side of the driver seat DS as shown in FIG. It becomes. In the case of the embodiment, the length dimension of the hypotenuse 49c of the shielding member 49 is such that the shielding member 49 can guide the driver as the separation side occupant to the second receiving body (front airbag) side. The length is set such that a slack is provided between the upper end 49a and the front end 49b when the deployment is completed. The shielding material 49 is not limited to a woven fabric as long as it is a flexible sheet material, and may be composed of a synthetic resin film material or a net, for example.

  In the embodiment, the side airbag 18 (first receiving body) is housed below the console box 3 and once protrudes rearward from below the console box 3, and then upwards. Although it is the structure which expand | swells so that it may expand | deploy, the accommodation position of a side airbag and the protrusion direction of a side airbag are not restricted to this. For example, as shown in FIG. 14, the side airbags 18A and 18B can be accommodated on the right side of the driver's seat or the passenger seat. In such a case, the side airbags 18A and 18B are projected to the front side during operation. Furthermore, as shown in FIG. 15, the side airbag 18C may be accommodated in the ceiling R and inflated so as to protrude downward when activated. Furthermore, although not shown, the side airbag may be accommodated in the console box so as to protrude upward from the console box.

  Further, in the occupant protection device M of the embodiment, the side airbag 18 fixes the rear end 19b side when the operation is completed to the case 11 side and fixes it to the vehicle body 1 side, and the front end 19a side is operated. Since the driver DP is arranged as a free end movable in the left-right direction so that the driver DP can be guided to the front airbag 31 side, the side airbag 18 receiving the driver DP The driver DP is guided to the front airbag 31 side while being moved by the driver DP so that the front end 19a faces the left side. Therefore, the driver DP can be reliably guided to the front airbag 31 side by the side airbag 18 as the first receiving body. Of course, if this point is not taken into consideration, the side airbag 18 as the first receiving body does not have to be arranged with the front end side at the time of completion of inflation as a free end, for example, a passenger seat and a driver seat. The side airbag is housed in the vicinity of the lower side of the instrument panel disposed in front of the front panel, and when operated, the airbag is protruded from the front side toward the rear side, and further projected upward, It is good also as a structure expand | swelled so that it may arrange | position between driver's seats.

  Furthermore, in the occupant protection device M of the embodiment, during operation, the window-side airbag 41 that constitutes a support body that can support the front-side airbag 31 on the collision side (left side) when the operation of the front-side airbag 31 is completed. However, since the inflation is completed, the front airbag 31 can be supported by the window airbag 41. In the occupant protection device M of the embodiment, since the second receiving body is configured by the front airbag 31, the driver DP can be received with good cushioning properties. However, when the driver DP receives the driver DP, There is a risk of swinging left and right under the pressure of DP (see the two-dot chain line in FIG. 10). However, in the occupant protection device M according to the embodiment, even if the front airbag 31 that has been inflated is swung by receiving the pressing force of the driver DP, the collision side (left side) is used as the window side air as a support. Since it can be supported by the bag 41, the driver side DP can be received accurately while the cushion effect is secured by the front airbag 31 whose swing is suppressed. Of course, if such a point is not considered, it is good also as a structure which does not arrange | position the window side airbag 41 (window side airbag apparatus A3) which comprises a support body.

  As the support, the window-side airbag 41 may not be used. For example, an airbag device having the same configuration as the side-side airbag device A1 is disposed on the left side (collision side) of the passenger seat PS, It is good also as a structure which uses the airbag of this airbag apparatus which expand | swells so that the left side of the passenger seat PS may be covered at the time of operation | movement as a support body. Furthermore, the airbag of the side-impact airbag device that is normally folded and stored in the backrest portion of the passenger seat so as to protect the outside of the passenger seated in the passenger seat is used as a support. Also good. When a side-impact airbag is used in this way, the capacity of the side-impact airbag can be made variable in accordance with the collision mode, and small when protecting a passenger seated in a normal passenger seat. It can also be configured to be inflated with a capacity and to be inflated with a large capacity and used as a support when protecting the driver who is a occupant on the remote side. Furthermore, when a window-side airbag is used as the support, unlike a normal head protecting airbag, the window W1 is not the entire structure of the windows W1 and W2 as in the embodiment. You may use the window side airbag of the structure covered. Furthermore, the support body is not limited to the airbag. For example, during operation, the support body protrudes from the upper surface of the instrument panel so as to cover the left side of the front airbag constituting the second receiving body, and the left side of the front airbag. You may comprise a support body from the plate-shaped member etc. which support this.

  Furthermore, in the occupant protection device M of the embodiment, the side airbag 18 and the front airbag 31 are formed by the front end 19a of the side airbag 18 and the rear end 31a of the front airbag 31 when the operation is completed. Are arranged so as to overlap in a projected state in the left-right direction of the vehicle. That is, in the occupant protection device M of the embodiment, when the side airbag 18 is pushed by the moving driver DP and moves so that the front end 19a is directed toward the collision side (left side), the side air The front end 19 a of the bag 18 comes into contact with the right side surface 31 b at the rear end 31 a of the front airbag 31. Therefore, the side airbag 18 can receive the driver DP in a state in which the restraint force in a state where the front end 19a side is supported by the front airbag 31 is improved. Of course, when the driver DP in contact with the side airbag 18 moves further diagonally leftward, the side airbag 18 is located on the front end 19a side as shown by the two-dot chain line in FIG. Guiding the driver DP to the front airbag 31 side while moving the front end 19a toward the collision side (left side) so that the contact state with the front airbag 31 is released. Become. The driver DP is guided by the side airbag 18 and comes into contact with the right side surface 31b (rear right corner area) at the rear end 31a of the front airbag 31. It will be received by the front airbag 31 so as to be greatly recessed from the rear right corner side. As a result, in the occupant protection device M according to the embodiment, the driver DP moving toward the left front side can be received by the side airbag 18 with increased restraining force. The driver DP that could not be received by the vehicle is absorbed in the kinetic energy by the guided movement of the side airbag 18 and is then received by the front airbag 31, so that the side airbag 18 and the front airbag The driver DP can be accurately received by the bag 31.

  In the embodiment, the side airbag 18 is configured to complete the inflation by bringing the front end 19a into contact with the right side surface 31b of the rear end 31a of the front airbag 31. As shown in FIG. 16, the front end 19a of the side airbag 18C and the rear end 31a of the front airbag 31A are disposed so as to overlap in the projected state in the left-right direction of the vehicle when the inflation is completed. However, it is good also as a structure arrange | positioned in the state which does not contact | abut mutually. Further, as shown in FIG. 17, the front end 19a of the side airbag 18D and the rear end 31a of the front airbag 31B are in contact with each other when the inflation is completed, but are projected in the left-right direction of the vehicle. You may comprise so that it may not mutually overlap in a state. Furthermore, if the above points are not taken into consideration, the front end of the side airbag and the rear end of the front airbag do not overlap in the left-right projection state of the vehicle and have a gap in the left-right direction. It is good also as a structure arrange | positioned in the position which does not contact each other when expansion | swelling is completed.

  In addition, in the embodiment, in the case of a side collision from the side (left side) of the passenger seat, the description has been given by taking as an example a device that protects the driver seated in the driver seat as the separated seat as the separated passenger, of course, The present invention may be applied to a device that protects an occupant seated in a passenger seat as a separated side seat as a separated side occupant during a side collision from the side (right side) of the driver seat. In the case of an occupant protection device that protects an occupant seated in a passenger seat as a remote occupant, the second catching body is an airbag of an airbag device for a steering wheel that is disposed in front of a driver seat as a close side seat. And it will be comprised from the airbag SA (refer the dashed-two dotted line of FIG. 9) changed into the structure which can support a 1st receiving body. Of course, also in the case of an occupant protection device that protects an occupant seated in the passenger seat, it is preferable to arrange a window-side airbag device that constitutes a support body on the side of the driver's seat. Furthermore, such an occupant protection device is not limited to a device that protects an occupant seated in the front seat of the vehicle, and may be configured to protect an occupant seated in the rear seat of the vehicle.
