根据本发明的一个实施例，所述拉带的另一端固定到处于膨胀且展开状态下的所述远侧面安全气囊的与朝向就坐在所述车辆座椅上的乘员一侧 相反的一侧表面上。According to an embodiment of the present invention, the other end of the draw tape is fixed to the occupant side of the far side airbag in an expanded and unfolded state and is seated on the vehicle seat On the opposite side of the surface.
根据本发明的一个实施例，所述充气装置经由连接构件固定到所述导杆上。According to an embodiment of the invention, the inflator is fixed to the guide rod via a connecting member.
由于远侧面安全气囊固定在头枕的内侧部中，因此，当侧面撞击发生时或预测到侧面撞击不可避免时，远侧面安全气囊能够在在较短的响应时间内膨胀且展开到乘员的头部位置，相对于安装在车辆座椅靠背中的远侧面安全气囊，更容易且更有效地保护乘员的头部。Since the far side airbag is fixed in the inner side portion of the headrest, the far side airbag can be inflated and deployed to the occupant's head in a short response time when a side impact occurs or when a side impact is unavoidable. The position of the occupant is easier and more effective in protecting the occupant's head relative to the far side airbag mounted in the vehicle seat back.
此外，远侧面安全气囊还经由拉带连接到座椅的导杆上。这样，当乘员由于侧面撞击的冲击力而撞击到远侧面安全气囊上时，拉带可以向远侧面安气囊提供相反方向的拉力，从而能够抑制远侧面安全气囊由于乘员的冲击而朝向车辆宽度方向内侧的运动，从而向乘员提供有效的支撑和保护。In addition, the far side airbag is also connected to the guide of the seat via a drawstring. In this way, when the occupant hits the far side airbag due to the impact force of the side impact, the pull belt can provide the opposite side pulling force to the far side airbag, thereby suppressing the far side airbag toward the vehicle width direction due to the impact of the occupant. The inside movement provides effective support and protection to the occupant.

图1和图2中示出的远侧面安全气囊组件14是在发生车辆的侧面碰撞时用于在座椅的车辆宽度方向的内侧支撑和保护乘员的装置。根据本发明的一个实施例，远侧面安全气囊组件14布置在头枕12的位于车辆宽度方向的内侧的侧部12A中。如图2所示，远侧面安全气囊组件14可以包括远侧面安全气囊28、充气装置30以及拉带32。其中，充气装置30用于 向安全气囊28喷射气体以使其膨胀且展开；拉带32的一端固定到导杆20上，并且另一端固定到安全气囊28上。下面，将详细描述远侧面安全气囊组件14的各个构件。The far side airbag module 14 shown in FIGS. 1 and 2 is a device for supporting and protecting an occupant on the inner side in the vehicle width direction of the seat when a side collision of the vehicle occurs. According to an embodiment of the present invention, the far side airbag module 14 is disposed in the side portion 12A of the headrest 12 on the inner side in the vehicle width direction. As shown in FIG. 2, the distal side airbag assembly 14 can include a distal side airbag 28, an inflator 30, and a drawstring 32. Wherein, the inflator 30 is used Gas is ejected to the air bag 28 to be inflated and deployed; one end of the pull band 32 is fixed to the guide bar 20, and the other end is fixed to the air bag 28. Hereinafter, the respective members of the distal side airbag module 14 will be described in detail.
具体地，安全气囊28以折叠的方式布置(即，隐藏)在头枕12的沿车辆宽度方向的内侧部12A中。如图2所示，安全气囊28可以折叠成大致长条状，且其长度方向沿头枕12的高度方向布置。拉带32也与安全气囊28一起折叠。当车辆遭遇侧面碰撞时，安全气囊28通过从充气装置30供应的气体从头枕内侧部12A朝向座椅的前方和下方(即，在车辆宽度方向上朝向乘员的内侧)膨胀且展开。安全气囊28可以通过将一块或多块(尼龙或聚酯等材料的)底布进行缝合而形成。但是，安全气囊28的制造方法不限于此。例如，安全气囊28还可以通过使用自动织布机进行一片式编织制成。Specifically, the airbag 28 is disposed in a folded manner (ie, concealed) in the inner side portion 12A of the headrest 12 in the vehicle width direction. As shown in FIG. 2, the airbag 28 can be folded into a substantially elongated shape, and its longitudinal direction is arranged along the height direction of the headrest 12. The draw tape 32 is also folded together with the air bag 28. When the vehicle encounters a side collision, the airbag 28 is inflated and deployed by the gas supplied from the inflator 30 from the headrest inner portion 12A toward the front and the bottom of the seat (ie, toward the inside of the occupant in the vehicle width direction). The airbag 28 can be formed by sewing one or more pieces of a base fabric (material such as nylon or polyester). However, the method of manufacturing the airbag 28 is not limited to this. For example, the airbag 28 can also be made by one-piece weaving using an automatic loom.
充气装置30例如可以形成为筒状。与安全气囊28类似，其充气装置30的轴向方向沿着头枕12的高度方向布置。具体地，充气装置30的轴向方向沿大致平行于内侧杆22的方向布置，并且优选地固定到内侧杆22上。The inflator 30 can be formed, for example, in a tubular shape. Similar to the airbag 28, the axial direction of the inflator 30 is arranged along the height direction of the headrest 12. Specifically, the axial direction of the inflator 30 is disposed in a direction substantially parallel to the inner rod 22, and is preferably fixed to the inner rod 22.
图3示出了处于膨胀且展开状态下的远侧面安全气囊28的形状及其固定方式的示意图。如图3所示，处于膨胀且展开状态的安全气囊28从侧面观察时形成为沿车辆竖直方向的大致矩形形状或大致椭圆形形状。处于膨胀且展开状态的安全气囊28至少能够支撑和保护乘员的头部，而且还能够支撑和保护乘员的胸部。例如，处于膨胀且展开状态的安全气囊28的上部28A位于乘员的头部沿车辆宽度方向的内侧，下部28B位于乘员的胸部的沿车辆宽度方向的内侧。此外，远侧面安全气囊28还可以包括一非充气区域28C。该非充气区域28C可以固定到充气装置30上从而固定到导杆20的内侧杆22上，使得安全气囊28固定到充气装置30以及导杆20的内侧杆22上。需要注意的是，该非充气区域28C位于膨胀且展开状态下的安全气囊28的上部28A的后侧边缘。由于安全气囊28的非充气区域28C相对于头枕12固定，便于安全气囊28从头枕内侧部12A相对于头枕12朝向前方和下方膨胀且展开。Figure 3 shows a schematic view of the shape of the distal airbag 28 in its expanded and deployed state and the manner in which it is secured. As shown in FIG. 3, the airbag 28 in an expanded and deployed state is formed into a substantially rectangular shape or a substantially elliptical shape in the vertical direction of the vehicle when viewed from the side. The inflated and deployed airbag 28 is at least capable of supporting and protecting the occupant's head, and is also capable of supporting and protecting the occupant's chest. For example, the upper portion 28A of the airbag 28 in the inflated and deployed state is located on the inner side of the occupant's head in the vehicle width direction, and the lower portion 28B is located on the inner side in the vehicle width direction of the occupant's chest. Additionally, the distal side airbag 28 can also include a non-inflated region 28C. The non-inflated region 28C can be secured to the inflator 30 to be secured to the inboard bar 22 of the guide bar 20 such that the air bag 28 is secured to the inflator 30 and the inboard bar 22 of the guide bar 20. It is noted that the non-inflated region 28C is located at the rear side edge of the upper portion 28A of the airbag 28 in the expanded and deployed state. Since the non-inflated region 28C of the airbag 28 is fixed with respect to the headrest 12, the airbag 28 is easily expanded and deployed from the headrest inner portion 12A toward the front and the bottom with respect to the headrest 12.
当远侧面安全气囊28膨胀且展开时，拉带32也随之展开。拉带32形 成为长条状。优选地，拉带32的第一端32A固定到导杆20的内侧杆22上。拉带32可以系、缠绕或者通过任何其他可行的方式固定到内侧杆22上。此外，拉带32的第一端32A也可以固定到导杆20的其他位置处，例如外侧杆24或横向杆26上。拉带32的另一端32B固定到安全气囊28上。拉带32可以通过缝合、粘贴、热焊接或者任何其他可行的方式固定到安全气囊28上。因此，拉带32在导杆20与远侧面安全气囊28之间延伸，并且拉带32在远侧面安全气囊28上的固定位置、延伸方向等可以适当的设置，以便于拉带32向远侧面安全气囊28施加适当的拉力，使得远侧面安全气囊28可以从头枕内侧部12A相对于头枕12向前且向下膨胀且展开。When the distal side airbag 28 is inflated and deployed, the drawstring 32 also unfolds. Pull belt 32 Become a long strip. Preferably, the first end 32A of the drawstring 32 is secured to the inner rod 22 of the guide bar 20. The draw tape 32 can be tied, wrapped or otherwise secured to the inner rod 22 by any other feasible means. Additionally, the first end 32A of the drawstring 32 can also be secured to other locations of the guide bar 20, such as the outer bar 24 or the transverse bar 26. The other end 32B of the draw tape 32 is fixed to the air bag 28. The draw tape 32 can be secured to the air bag 28 by stitching, gluing, heat welding, or any other feasible means. Therefore, the draw tape 32 extends between the guide bar 20 and the far side air bag 28, and the fixed position, the extending direction, and the like of the pull tape 32 on the far side air bag 28 can be appropriately set so as to facilitate the draw tape 32 to the far side. The airbag 28 applies an appropriate pulling force so that the far side airbag 28 can be swollen and deployed forward and downward from the headrest inner side portion 12A with respect to the headrest 12.
如图3所示，拉带32的另一端32B固定到处于膨胀且展开状态下的安全气囊28的朝向就坐在座椅10上的乘员一侧的表面上。具体地，拉带32的另一端32B可以固定到处于膨胀且展开状态下的安全气囊28的上部28A和下部28B之间(大致对应于乘员的肩膀的高度)沿车辆前后方向的预定位置处，例如沿车辆前后方向的中间位置或前端。此外，在安全气囊28处于膨胀且展开状态时，拉带32可以在上部28A和下部28B之间的位置处沿车辆的前后方向从安全气囊28的后侧边缘延伸到前侧边缘。此外，拉带32也可以在上部28A和下部28B之间的位置处从后侧边缘仅延伸到前后侧边缘之间的中间位置处，或者延伸到中间位置与前侧边缘之间的其他适合的位置处。As shown in FIG. 3, the other end 32B of the drawstring 32 is fixed to the surface of the occupant side on the seat 10 in the direction in which the airbag 28 is in the inflated and deployed state. Specifically, the other end 32B of the draw tape 32 may be fixed to a predetermined position in the front-rear direction of the vehicle between the upper portion 28A and the lower portion 28B of the airbag 28 in the expanded and deployed state (corresponding to the height of the shoulder of the occupant), For example, in the middle or front end of the vehicle in the front-rear direction. Further, when the airbag 28 is in the expanded and unfolded state, the draw tape 32 may extend from the rear side edge of the airbag 28 to the front side edge in the front-rear direction of the vehicle at a position between the upper portion 28A and the lower portion 28B. Further, the draw tape 32 may also extend from the rear side edge to an intermediate position between the front and rear side edges at a position between the upper portion 28A and the lower portion 28B, or may extend to other suitable between the intermediate position and the front side edge.

或者，拉带32的另一端32B也可以固定到处于膨胀且展开状态下的安全气囊28的沿车辆前后方向的前部的适合位置处。此外，拉带32的另一端32B还可以固定到处于膨胀且展开状态下的安全气囊28的下部28B的适合位置处。需要注意的是，拉带32的另一端32B的固定位置和方式并不限于以上实施例，拉带32的另一端32B可以任何适合的方式固定到远侧面安全气囊28的适合的位置处，以便于远侧面安全气囊28能够从头枕内侧部12A向前向下展开，并且便于沿车辆宽度方向的内侧支撑和保护座椅上的乘员。Alternatively, the other end 32B of the drawstring 32 may also be fixed to a suitable position of the front portion of the airbag 28 in the expanded and unfolded state in the vehicle front and rear direction. Additionally, the other end 32B of the drawstring 32 can also be secured to a suitable location of the lower portion 28B of the airbag 28 in the expanded and deployed state. It should be noted that the fixed position and manner of the other end 32B of the strap 32 is not limited to the above embodiment, and the other end 32B of the strap 32 can be fixed to a suitable position of the distal airbag 28 in any suitable manner so that The distal side airbag 28 can be deployed forward and downward from the headrest inner side portion 12A, and facilitates supporting and protecting the occupant on the seat in the vehicle width direction inner side.
在上述实施例中，充气装置30直接固定到导杆20的内侧杆22上，但是，本发明不限于此。根据本发明的其他实施例，充气装置30也可以经 由额外的连接构件固定到内侧杆22上。图4A和图4B示出了根充气装置30经由额外的连接构件固定到导杆上的示意图，其中图4A是从座椅的沿车辆前后方向的前方朝向后方观察得到的视图，并且图4B是从座椅的沿车辆宽度方向的外侧朝向内侧观察得到的视图。如图4A和4B所示，充气装置30通过螺栓(一对或多个)等紧固件固定到连接构件34上，连接构件34通过焊接等方式固定到内侧杆22上。连接构件34例如可以形成为矩形状薄板。此外，充气装置30的螺栓还可以同时穿过安全气囊28的非充气区域28C，使得安全气囊28同时固定到充气装置30和连接构件34(导杆20的内侧杆22)上，从而固定处于膨胀且展开状态下的安全气囊28的上部28A的后侧边缘。In the above embodiment, the inflator 30 is directly fixed to the inner rod 22 of the guide bar 20, but the invention is not limited thereto. According to other embodiments of the invention, the inflator 30 can also It is fixed to the inner rod 22 by an additional connecting member. 4A and 4B are views showing the root inflator 30 fixed to the guide bar via an additional connecting member, wherein FIG. 4A is a view seen from the front of the seat in the front-rear direction of the vehicle toward the rear, and FIG. 4B is a view A view seen from the outer side of the seat in the vehicle width direction toward the inner side. As shown in FIGS. 4A and 4B, the inflator 30 is fixed to the connecting member 34 by a fastener such as a bolt (one or more), and the connecting member 34 is fixed to the inner rod 22 by welding or the like. The connecting member 34 can be formed, for example, as a rectangular thin plate. Further, the bolts of the inflator 30 can also pass through the non-inflated region 28C of the airbag 28 at the same time, so that the airbag 28 is simultaneously fixed to the inflator 30 and the connecting member 34 (the inner rod 22 of the guide rod 20), so that the fixation is inflated. And the rear side edge of the upper portion 28A of the airbag 28 in the unfolded state.
图5示出了根据本发明的一个实施例的头枕中撕裂用缝合部。此外，根据本发明的实施例，安全气囊28在膨胀且展开之前，安全气囊组件14隐藏在头枕12中，即，被头枕12的外罩覆盖。外罩由多个罩缝合而成，例如外罩可以包括前罩40、内侧罩42、外侧罩44和后罩46，如图4所示。其中，前罩40和内侧罩42之间的缝合部48用作撕裂用缝合部。缝合部48沿着头枕12的内侧部12A的前端边缘在头枕的高度方向上延伸，并且在安全气囊28膨胀且展开时通过安全气囊28的膨胀压力而撕裂，从而形成用于安全气囊28向头枕12的外侧膨胀且展开的开口。此外，安全气囊28的撕裂用缝合部还可以包括由内侧罩42的下端部和后罩46的下端部(或者额外的底罩)之间的缝合部，还可以包括前罩40与后罩46的下端部(或者额外的底罩)之间的缝合部靠近头枕12的内侧部12A的部分。这样的缝合部在安全气囊28膨胀且展开时可以形成朝向头枕12的下方的开口，有利于安全气囊28向头枕12的下方膨胀且展开。因此，位于头枕12的内侧部12A的前侧的撕裂用缝合部结合位于内侧部12A的下侧的撕裂用缝合部，便于安全气囊28相对于内侧部12A向前和向下膨胀且展开。Figure 5 illustrates a tear seam in a headrest in accordance with one embodiment of the present invention. Moreover, in accordance with an embodiment of the present invention, the airbag module 14 is concealed in the head restraint 12, i.e., by the outer cover of the head restraint 12, prior to inflation and deployment. The outer cover is sewn from a plurality of covers, for example, the outer cover may include a front cover 40, an inner cover 42, an outer cover 44, and a rear cover 46, as shown in FIG. Among them, the sewn portion 48 between the front cover 40 and the inner cover 42 serves as a sewn portion for tearing. The sewn portion 48 extends in the height direction of the headrest along the front end edge of the inner side portion 12A of the headrest 12, and is torn by the inflation pressure of the airbag 28 when the airbag 28 is inflated and deployed, thereby forming an airbag for airbag An opening that is inflated and deployed to the outside of the headrest 12. In addition, the tear seaming portion of the airbag 28 may further include a seam portion between the lower end portion of the inner side cover 42 and the lower end portion (or an additional bottom cover) of the rear cover 46, and may further include a front cover 40 and a rear cover The stitched portion between the lower end portion (or the additional bottom cover) of 46 is near the portion of the inner side portion 12A of the headrest 12. Such a sewn portion can form an opening toward the lower side of the headrest 12 when the airbag 28 is inflated and deployed, which facilitates expansion and deployment of the airbag 28 below the headrest 12. Therefore, the tearing sewn portion on the front side of the inner side portion 12A of the headrest 12 is combined with the tearing sewn portion on the lower side of the inner side portion 12A, facilitating the airbag 28 to expand forward and downward with respect to the inner side portion 12A and Expand.
如图3所示，安装在车辆上的电子控制单元36电连接至充气装置30。检测车辆的侧面碰撞的侧面碰撞传感器38电连接至该电子控制单元36。电子控制单元36被构造为当基于来自侧面碰撞传感器38的信号而检测到车辆的侧面碰撞或车辆的侧面碰撞不可避免时对充气装置30进行操作。 As shown in FIG. 3, an electronic control unit 36 mounted on the vehicle is electrically connected to the inflator 30. A side impact sensor 38 that detects a side impact of the vehicle is electrically coupled to the electronic control unit 36. The electronic control unit 36 is configured to operate the inflator 30 when a side collision of the vehicle is detected based on a signal from the side impact sensor 38 or a side collision of the vehicle is unavoidable.
具体地，根据本发明实施例的远侧面安全气囊组件14安装在车辆座椅10的头枕12中。因此，当电子控制单元36检测到另一车辆已经与座椅10所在车辆的侧面发生碰撞时，激活充气装置30。此外，在预测侧面碰撞的预撞击传感器电连接至电子控制单元36的情况下，充气装置30可以被构造为当电子控制单元36基于来自预撞击传感器的信号预测到侧面碰撞时而被激活。Specifically, the far side airbag module 14 according to an embodiment of the present invention is mounted in the headrest 12 of the vehicle seat 10. Therefore, when the electronic control unit 36 detects that another vehicle has collided with the side of the vehicle in which the seat 10 is located, the inflator 30 is activated. Further, in the case where the pre-impact sensor predicting a side collision is electrically connected to the electronic control unit 36, the inflator 30 may be configured to be activated when the electronic control unit 36 predicts a side collision based on a signal from the pre-impact sensor.
当充气装置30被激活时，充气装置30使得远侧面安全气囊28充气并冲破撕裂用缝合部，而从头枕12中相对于乘员在车辆宽度方向的内侧向前并向下膨胀且展开。When the inflator 30 is activated, the inflator 30 inflates and breaks the tear side airbag 28, and expands and unfolds from the headrest 12 forward and downward in the vehicle width direction with respect to the occupant.
此外，处于膨胀且展开状态下的安全气囊28的上部28A的后端部28C固定到导杆20的内侧杆22上，此外，拉带32的一端32A固定到导杆20上，另一端32B固定到安全气囊28上。Further, the rear end portion 28C of the upper portion 28A of the airbag 28 in the inflated and deployed state is fixed to the inner side rod 22 of the guide bar 20, and further, one end 32A of the pull band 32 is fixed to the guide bar 20, and the other end 32B is fixed. Go to the airbag 28.
由于远侧面安全气囊28固定在头枕12的内侧部12A中，因此，到侧面撞击发生时或预测到侧面撞击不可避免时，远侧面安全气囊28能够在在较短的响应时间内膨胀且展开到乘员的头部位置，相对于安装在车辆座椅靠背中的远侧面安全气囊，更容易且更有效地保护乘员的头部。Since the distal side airbag 28 is fixed in the inner side portion 12A of the headrest 12, the far side airbag 28 can be inflated and deployed in a short response time when a side impact occurs or when a side impact is unavoidable. To the occupant's head position, it is easier and more effective to protect the occupant's head relative to the far side airbag mounted in the vehicle seat back.
此外，远侧面安全气囊28还经由拉带32连接到座椅的导杆20上。这样，当乘员由于侧面撞击的冲击力而撞击到远侧面安全气囊28上时，拉带32可以向远侧面安气囊28提供相反方向的拉力，从而能够抑制远侧面安全气囊28由于乘员的冲击而朝向车辆宽度方向内侧的运动，从而向乘员提供有效的支撑和保护。In addition, the distal side airbag 28 is also coupled to the guide bar 20 of the seat via a drawstring 32. Thus, when the occupant hits the far side airbag 28 due to the impact of the side impact, the pull belt 32 can provide the pulling force in the opposite direction to the far side airbag 28, thereby suppressing the impact of the far side airbag 28 due to the impact of the occupant. Movement toward the inside of the vehicle width direction provides effective support and protection to the occupant.

However, embodiments of the present invention are not limited thereto, and the 12-bed headrest may be integrally formed with the seat back.
此外，在上述实施例中，拉带32固定到远侧面安全气囊28的朝向乘员一侧的表面上。但本发明的实施例不限于此，拉带32也可以固定到远侧面安全气囊28的朝向与就坐在座椅10上的乘员的一侧相反的一侧表面上。Further, in the above embodiment, the draw tape 32 is fixed to the surface of the far side airbag 28 facing the occupant side. However, the embodiment of the present invention is not limited thereto, and the draw tape 32 may be fixed to the side surface of the far side airbag 28 opposite to the side of the occupant sitting on the seat 10.
此外，在上述实施例中，远侧面安全气囊28还包括非充气区域28C。 但是，本发明的实施例不限于此，远侧面安全气囊28也可以不包括非充气区域28C，但仍然可以实现其功能。Further, in the above embodiment, the distal side airbag 28 further includes a non-inflated area 28C. However, embodiments of the present invention are not limited thereto, and the far side airbag 28 may not include the non-inflated area 28C, but its function can still be achieved.
