Description

サイドエアバッグ装置Side airbag device
　本発明は、車体側方から加えられる衝撃を緩和するためのサイドエアバッグ装置に係り、特に、車体と後部座席との間に配置されるサイドエアバッグ装置に関するものである。 The present invention relates to a side airbag device for reducing impact applied from the side of a vehicle body, and more particularly to a side airbag device disposed between a vehicle body and a rear seat.
　従来、車体幅方向において車体ドアと後部座席との間に配置されるサイドエアバッグ装置として、エアバッグの内部にガスを注入するインフレータと、エアバッグおよびインフレータを格納する格納ボックスと、格納ボックスを車体前方側から覆う樹脂製のベースカバーと、を備えたものが知られている（例えば、特許文献１、２参照）。 Conventionally, as a side airbag device disposed between a vehicle body door and a rear seat in the vehicle body width direction, an inflator for injecting gas into the airbag, a storage box for storing the airbag and the inflator, and a storage box A resin base cover that covers from the front side of the vehicle body is known (for example, see Patent Documents 1 and 2).
　特許文献１に記載されたサイドエアバッグ装置では、金属製の格納ボックスに格納されたエアバッグをインフレータで膨張させると、エアバッグが車体前方側にある樹脂製のベースカバーの薄肉部を破壊して膨出展開する構成となっている。
　詳しく説明すると、車体側方から所定値以上の衝撃が加わったときに不図示の衝撃センサが感知し、インフレータに点火用電力が供給され、エアバッグが着座者の側方で膨張展開することになる。 In the side airbag device described in Patent Document 1, when an airbag stored in a metal storage box is inflated with an inflator, the airbag destroys the thin wall portion of the resin base cover on the front side of the vehicle body. It is configured to bulge and expand.
More specifically, when an impact of a predetermined value or more is applied from the side of the vehicle body, an impact sensor (not shown) senses, the ignition power is supplied to the inflator, and the airbag is inflated and deployed on the side of the seated person. Become.
　また、特許文献２に記載された側突用エアバッグ装置では、エアバッグ及びインフレータが格納されたエアバッグモジュールを後部座席の側方部に備え、エアバッグモジュールの前方面にクッションパッドが載置されて表皮カバーで覆われて構成されている。
　このとき、エアバッグの膨出方向が表皮カバーに設けられた開裂部に集中するように、表皮カバー背面の車外側に相当する部分には力布が取り付けられている。
　上記構成によって、エアバッグが車体前方側にある表皮カバーの開裂部に向けて膨出展開することになる。 Moreover, in the airbag apparatus for side collision described in patent document 2, the airbag module in which the airbag and the inflator were stored is provided in the side part of a rear seat, and a cushion pad is mounted in the front surface of an airbag module. It is made up of covered with a skin cover.
At this time, a webbing is attached to a portion corresponding to the vehicle outer side on the back surface of the skin cover so that the bulging direction of the airbag is concentrated on the tearing portion provided on the skin cover.
With the above configuration, the airbag is inflated and deployed toward the cleaving portion of the skin cover on the front side of the vehicle body.

　ところで、特許文献１、２のようなサイドエアバッグ装置では、一般にエアバッグの膨出展開方向をガイドする力布が、表皮カバー側に一端部が取り付けられ、他端部がエアバッグモジュール側に取り付けられて構成されている。
　そのため、インフレータが作動してエアバッグが膨出するときに、インフレータのガス圧力がエアバッグモジュール周辺に負荷されることで、力布の他端部とエアバッグモジュール側との取り付けが不安定になって、エアバッグの膨出展開方向に影響を与える虞があった。
　そこで力布の取り付け剛性を確保することで、エアバッグの膨出展開方向を安定させることが可能な技術が望まれていた。 By the way, in a side airbag device such as Patent Documents 1 and 2, generally, a webbing that guides the direction of inflation and deployment of an airbag has one end attached to the skin cover side and the other end to the airbag module side. Installed and configured.
For this reason, when the inflator is activated and the airbag is inflated, the gas pressure of the inflator is applied to the periphery of the airbag module, so that the attachment of the other end of the webbing and the airbag module side becomes unstable. Thus, there is a possibility of affecting the bulging and deploying direction of the airbag.
Therefore, a technique capable of stabilizing the bulging and deploying direction of the airbag by ensuring the attachment rigidity of the bundling has been desired.
　また、特許文献１のようなサイドエアバッグ装置は、車体ドアと後部座席との間の狭い空間に嵌まるように組み付けられているため、サイドエアバッグ装置のコンパクト化を図り、各構成部品の組み付け作業を簡便にすることが望まれていた。
　特に、エアバッグの膨出方向をガイドする力布は、比較的複雑な配置となっているため、力布の組み付け作業を容易にすることが望まれていた。 Moreover, since the side airbag apparatus like patent document 1 is assembled | attached so that it may fit in the narrow space between a vehicle body door and a rear seat, the size reduction of a side airbag apparatus is achieved, It has been desired to simplify the assembly work.
In particular, the force cloth that guides the bulging direction of the airbag has a relatively complicated arrangement, and therefore it has been desired to facilitate the work of assembling the force cloth.
　また、特許文献１のようなサイドエアバッグ装置では、強度向上を図るべく格納ボックスを金属製としていたが、一方で軽量化を図るために樹脂製に変更することが求められており、格納ボックスを樹脂製に変更しても、エアバッグの膨出展開時における変形を抑制可能な技術が求められていた。 Further, in the side airbag device as in Patent Document 1, the storage box is made of metal in order to improve the strength, but on the other hand, it is required to change to a resin box in order to reduce the weight. Therefore, there has been a demand for a technique that can suppress the deformation of the airbag when the airbag is inflated and deployed, even if it is changed to resin.
　また、特許文献２のようなサイドエアバッグ装置では、エアバッグモジュールの前方面にクッションパッドが載置されているため、エアバッグが膨出展開するときに、クッションパッドが車体前方側に飛散する恐れや、クッションパッドが邪魔となってエアバッグの膨出展開方向に影響を与える恐れがあった。
　そのため、エアバッグの膨出展開時にエアバッグモジュールの前方面にあるクッションパッドを飛散させることなく、好適にエアバッグを車体前方側に展開させることが可能なサイドエアバッグ装置が望まれていた。 Further, in the side airbag device as in Patent Document 2, since the cushion pad is placed on the front surface of the airbag module, the cushion pad is scattered to the front side of the vehicle body when the airbag is inflated and deployed. There is a fear that the cushion pad may interfere with the airbag inflating and deploying direction.
Therefore, there has been a demand for a side airbag device that can suitably deploy the airbag to the front side of the vehicle body without scattering the cushion pad on the front surface of the airbag module when the airbag is inflated and deployed.
　本発明は、上記の課題に鑑みてなされたものであり、本発明の目的は、エアバッグの膨出展開方向を安定させることが可能なサイドエアバッグ装置を提供することにある。
　また、本発明の他の目的は、車体と後部座席との間の空間に配置され、コンパクト化及び組み付け作業の簡素化を図ったサイドエアバッグ装置を提供することにある。
　また、本発明の他の目的は、エアバッグが膨出展開するときに、エアバッグ及びインフレータを格納する格納ボックス周辺の変形を抑制可能なサイドエアバッグ装置を提供することにある。
　また、本発明の他の目的は、クッションパッドを飛散させることなく、好適にエアバッグを膨出展開させることが可能なサイドエアバッグ装置を提供することにある。 This invention is made | formed in view of said subject, and the objective of this invention is providing the side airbag apparatus which can stabilize the bulging and deploying direction of an airbag.
Another object of the present invention is to provide a side airbag device that is disposed in a space between a vehicle body and a rear seat and is compact and simplified in assembling work.
Another object of the present invention is to provide a side airbag device capable of suppressing deformation around the storage box storing the airbag and the inflator when the airbag is inflated and deployed.
Another object of the present invention is to provide a side airbag device capable of suitably inflating and deploying an airbag without scattering a cushion pad.
　前記課題は、本発明のサイドエアバッグ装置によれば、車体と後部座席との間に設けられるサイドエアバッグ装置であって、膨出可能なエアバッグと、該エアバッグの内部にガスを供給するインフレータと、折り畳まれた状態の前記エアバッグ及び前記インフレータを格納するベース格納部を有し、車体ドアと前記後部座席との間に取り付けられるベース部材と、該ベース部材を車体前方側から覆うカバー部材と、該カバー部材に一端側が取り付けられ、他端側が前記ベース部材に設けられた力布係止溝に係止され、前記エアバッグの膨出展開方向をガイドする力布と、前記ベース格納部、及び前記力布係止溝を車体後方側から覆うリテーナ部材と、を備え、前記力布の他端側には、前記力布係止溝に木目込まれる係止部材が取り付けられ、該係止部材は、前記力布係止溝から一部張り出すようにして該力布係止溝に木目込まれ、張り出し部分が前記リテーナ部材に向かって延びていること、により解決される。 According to the side airbag device of the present invention, the above-described problem is a side airbag device provided between a vehicle body and a rear seat, in which an inflatable airbag and gas are supplied into the airbag An inflator, a folded-up airbag, and a base storage portion for storing the inflator, and a base member attached between a vehicle body door and the rear seat, and covering the base member from the front side of the vehicle body A cover member, a baffle having one end attached to the cover member, the other end locked to a baffle locking groove provided in the base member, and guiding a bulging and deploying direction of the airbag; and the base And a retainer member that covers the baffle locking groove from the rear side of the vehicle body, and a locking member that is grained into the baffle locking groove is attached to the other end side of the blanching. Locking member, the webbing engaging groove Kimekomi rarely the force fabric locking grooves so as to protrude partially from that overhang extends toward said retainer member, is solved by.
　上記のように、リテーナ部材が、エアバッグ及びインフレータを格納するベース格納部と、力布の他端側を係止する力布係止溝とを車体後方側から同時に覆っているため、ベース格納部周辺の剛性だけでなく、力布の取り付け剛性も向上する。
　また、力布の他端側に設けられた係止部材が、力布係止溝から一部張り出すようにして力布係止溝に木目込まれ、張り出し部分がリテーナ部材に向かって延びているため、エアバッグの膨出展開時にガス圧力が力布係止溝周辺に負荷された場合にも、力布の係止部材が、リテーナ部材の保持によって力布係止溝から抜けてしまうことを抑制できる。すなわち、力布の取り付けが安定する。
　従って、エアバッグの膨出展開方向を車体前方側に安定させることが可能なサイドエアバッグ装置となる。
　さらに、力布の他端側にある係止部材が、力布係止溝から一部張り出すようにして力布係止溝に木目込まれているため、係止部材の力布係止溝に対する取り付けや取り外しが容易になる。具体的には、作業者が係止部材の張り出し部分を把持しながら力布係止溝に着脱させることができるため、目視確認が困難な状況下で組み付け作業が容易かつ安定する。 As described above, the retainer member simultaneously covers the base storage portion for storing the airbag and the inflator and the force cloth locking groove for locking the other end side of the force cloth from the rear side of the vehicle body. Not only the rigidity around the part, but also the mounting rigidity of the power cloth is improved.
Further, the locking member provided on the other end side of the bundling is inserted into the baffle locking groove so as to partially protrude from the bundling locking groove, and the protruding portion extends toward the retainer member. Therefore, even when gas pressure is applied around the baffle locking groove when the airbag is inflated and deployed, the baffle locking member may come out of the baffle locking groove by holding the retainer member. Can be suppressed. That is, the attachment of the bundling is stable.
Accordingly, the side airbag device is capable of stabilizing the bulging and deploying direction of the airbag toward the front side of the vehicle body.
Furthermore, since the locking member on the other end side of the webbing is grained into the webbing locking groove so as to partially protrude from the webbing locking groove, the webbing locking groove of the locking member It becomes easy to attach to and remove from. Specifically, since the operator can attach and detach the forceps locking groove while gripping the protruding portion of the locking member, the assembling work is easy and stable under a situation where visual confirmation is difficult.
　このとき、前記ベース格納部は、前記エアバッグ及び前記インフレータの車体後方側に配置される後壁部と、該後壁部の車体幅方向の両端部から連続して車体前方側に延びる左右の側壁部と、を備え、前記力布係止溝は、前記左右の側壁部のうち、一方の側壁部に設けられていると良い。
　上記構成により、ベース格納部及び力布係止溝を車体後方側から覆うリテーナ部材をコンパクトに配置することができ、組み付け作業も容易になる。
　また、エアバッグ及びインフレータを格納するベース格納部近辺に力布係止溝が設けられているため、エアバッグの膨出展開方向をガイドする力布のガイド性が向上する。 At this time, the base storage portion includes a rear wall portion disposed on the vehicle body rear side of the airbag and the inflator, and left and right sides extending continuously from the both end portions of the rear wall portion in the vehicle body width direction to the vehicle body front side. It is good for the said baffle latching groove to be provided in one side wall part among the said left and right side wall parts.
With the above configuration, the retainer member that covers the base storage portion and the baffle locking groove from the rear side of the vehicle body can be arranged in a compact manner, and the assembling work is facilitated.
In addition, since the bedding locking groove is provided in the vicinity of the base storage portion for storing the airbag and the inflator, the guideability of the bedding that guides the inflation and deployment direction of the airbag is improved.
　このとき、前記力布係止溝は、前記一方の側壁部から車体幅方向に延びる底壁部と、該底壁部の延出部分から連続して車体後方側に延びる側壁部と、を備え、前記係止部材は、前記力布係止溝に木目込まれた状態で、前記張り出し部分が車体後方側にある前記リテーナ部材に向かって延びていると良い。
　上記構成により、リテーナ部材の車体後方側からの組み付け作業が一層容易になる。 At this time, the baffle locking groove includes a bottom wall portion extending in the vehicle body width direction from the one side wall portion, and a side wall portion extending continuously from the extending portion of the bottom wall portion to the vehicle body rear side. The locking member may extend toward the retainer member on the rear side of the vehicle body in a state where the locking member is inserted into the baffle locking groove.
With the above configuration, the assembly work of the retainer member from the rear side of the vehicle body is further facilitated.
　このとき、前記係止部材は、前記力布係止溝に木目込まれた状態で、一端が前記力布係止溝の底部分に当接し、他端となる前記張り出し部分が前記リテーナ部材に当接するように配置されていると良い。
　上記構成により、力布に設けられた係止部材が力布係止溝とリテーナ部材とで挟まれた状態で取り付けられるため、力布の取り付けが一層安定する。その結果、エアバッグの膨出展開方向を一層安定させることができる。 At this time, in the state where the locking member is wooded in the baffle locking groove, one end abuts on the bottom portion of the baffle locking groove, and the overhanging portion serving as the other end is on the retainer member. It is good to arrange so that it may contact.
With the above-described configuration, since the locking member provided on the webbing is attached while being sandwiched between the webbing locking groove and the retainer member, the mounting of the webbing is further stabilized. As a result, the bulging and deploying direction of the airbag can be further stabilized.
　このとき、前記力布は、前記カバー部材に取り付けられた一端部から連続して延びて、前記ベース部材に設けられた挿通孔を挿通し、他端部が前記力布係止溝に係止されてなり、前記係止部材は、前記力布の他端部において、前記力布係止溝に木目込まれる第１係止部材と、前記力布の延出方向において前記力布係止溝と前記挿通孔との間に配置される第２係止部材と、から少なくともなると良い。
　上記のように、力布の延出方向において力布係止溝と挿通孔との間に第２係止部材が配置されているため、力布の組み付け作業が容易になり、かつ、エアバッグの膨出展開方向が安定する。
　具体的には、力布の組み付け作業について、力布の他端部にある第１係止部材を挿通孔に挿通させて力布係止溝に木目込む際には、力布が張った状態になるため木目込み作業が困難になる。このとき、力布の他端側にある別の第２係止部材を挿通孔に挿通させた後、当該挿通孔周辺に引掛けた状態にすることで、第１係止部材の木目込み作業が格段に向上する。
　また、エアバッグの膨出展開時にガス圧力が負荷された場合についても、第２係止部材が挿通孔周辺に引掛かった状態で支持されることで、第１係止部材が力布係止溝から抜けてしまうことを抑制できる。そのため、力布の取り付けが安定し、エアバッグの膨出展開方向が安定する。 At this time, the baffle extends continuously from one end portion attached to the cover member, passes through an insertion hole provided in the base member, and the other end portion is locked in the baffle locking groove. The locking member includes: a first locking member that is grained into the baffle locking groove at the other end of the buffing cloth; and the baffle locking groove in the extending direction of the baffle. And a second locking member disposed between the insertion hole and the insertion hole.
As described above, since the second locking member is disposed between the baffle locking groove and the insertion hole in the extending direction of the buffing cloth, the assembling work of the bundling is facilitated and the airbag is used. The bulging and unfolding direction is stabilized.
Specifically, when assembling the blanket, when the first locking member at the other end of the blanket is inserted into the insertion hole and the grain is inserted into the blanching groove, the bundling is stretched. Therefore, the graining work becomes difficult. At this time, by inserting another second locking member on the other end side of the baffle into the insertion hole and then hooking it around the insertion hole, the graining operation of the first locking member is performed. Greatly improved.
In addition, even when gas pressure is applied when the airbag is inflated and deployed, the second locking member is supported in a state of being hooked around the insertion hole, so that the first locking member is hooked. It can suppress coming off from a groove | channel. For this reason, the attachment of the bundling is stable, and the bulging and deploying direction of the airbag is stabilized.
　このとき、前記第２係止部材は、前記力布が組み付けられた状態で、前記挿通孔の開口に対して幅広となるように配置されていると良い。
　上記構成により、第２係止部材が挿通孔周辺に一層引っ掛かり易い形状となるため、上述したように、力布の組み付け作業が一層容易になり、かつ、エアバッグの膨出展開方向が一層安定する。 At this time, the second locking member may be disposed so as to be wide with respect to the opening of the insertion hole in a state in which the webbing is assembled.
With the above configuration, the second locking member has a shape that is more easily hooked around the insertion hole, and as described above, the assembling work of the bedding is further facilitated, and the inflation and deployment direction of the airbag is more stable. To do.
　このとき、前記力布の前記他端側には、前記係止部材よりも前記他端側に延出している力布延出部が設けられていると良い。
　上記構成により、力布の組み付け作業が容易になる。
　具体的には、力布を組み付ける場合には、一般にカバー部材に一端側が縫着等で取り付けられた後、他端側を引っ張ってエアバッグモジュール側に設けられた力布係止溝に係止するところ、係止部材よりも他端側に延出している力布延出部を作業者が把持することで、力布の他端側を引っ張る作業、力布の他端側にある係止部材を力布係止溝に係止する作業が容易になる。
　特に、車体と後部座席との間の狭い空間に組み付けられるサイドエアバッグ装置の場合には、目視確認が困難な状況下で力布を複雑に配置する必要があるため、本発明が有意義なものとなる。 At this time, it is good for the said other end side of the said bedding to provide the bedding extension part extended to the said other end side rather than the said locking member.
With the above configuration, the assembly work of the bundling is facilitated.
Specifically, when assembling a baffle, generally one end side is attached to the cover member by sewing or the like, and then the other end side is pulled and locked in a baffle locking groove provided on the airbag module side. However, the operator pulls the other end side of the webbing when the operator grips the webbing extension extending from the locking member to the other end side, and the locking on the other side of the webbing. The operation | work which latches a member to a baffle latching groove becomes easy.
In particular, in the case of a side airbag device that is assembled in a narrow space between the vehicle body and the rear seat, the present invention is meaningful because it is necessary to dispose the bundling in a complicated situation in which visual confirmation is difficult. It becomes.
　このとき、前記力布延出部は、前記係止部材よりも厚みが薄くなるように形成されていると良い。
　また、前記力布延出部は、前記力布及び前記係止部材の少なくとも一方よりも幅狭となるように形成されていると良い。
　上記構成により、作業者が力布の他端部を引っ張って力布延出部を挿通孔に先に挿通させる作業が一層容易になる。その結果、力布の組み付け作業が格段に向上する。 At this time, it is preferable that the force extending portion is formed to be thinner than the locking member.
Moreover, it is good for the said bedding extension part to be formed so that it may become narrower than at least one of the said bedding and the said locking member.
With the above-described configuration, it becomes easier for the operator to pull the other end portion of the bundling and insert the bundling extension portion into the insertion hole first. As a result, the assembling work of the bundling is significantly improved.
　このとき、前記ベース部材のうち、少なくとも前記ベース格納部の車体前方側の位置に載置されるパッド部材を備え、前記カバー部材は、前記ベース部材及び前記パッド部材を車体前方側から覆う表皮材であって、前記力布は、前記パッド部材の少なくとも一部を覆うように延びて、該パッド部材と前記エアバッグとの間を通過していると良い。
　上記のように、力布は、パッド部材の少なくとも一部を覆うように延びて、パッド部材とエアバッグとの間を通過しているため、力布がパッド部材を保護しながらエアバッグの膨出展開方向をガイドすることができる。その結果、パッド部材の飛散を抑制し、好適にエアバッグを膨出展開させることができる。 At this time, among the base members, at least a pad member placed at a position on the vehicle body front side of the base storage portion is provided, and the cover member covers the base member and the pad member from the vehicle body front side. In this case, it is preferable that the baffle extends so as to cover at least a part of the pad member and passes between the pad member and the airbag.
As described above, the webbing extends so as to cover at least a part of the pad member and passes between the pad member and the airbag, so that the webbing inflates the airbag while protecting the pad member. It is possible to guide the unfolding direction. As a result, scattering of the pad member can be suppressed, and the airbag can be suitably inflated and deployed.
　このとき、前記力布は、前記表皮材に設けられた表皮開裂部に前記一端側が取り付けられ、前記エアバッグの膨出方向を前記表皮開裂部側にガイドし、該表皮開裂部は、車体幅方向において前記エアバッグに重なる位置に配置されていると良い。
　上記構成により、力布のガイド及び表皮開裂部の配置によって、エアバッグを車体前方側の真正面に向かって好適に膨出させることができる。 At this time, the one end side is attached to the skin cleaving portion provided in the skin material, and the baffle guides the bulging direction of the airbag to the skin cleaving portion side. It is good to arrange | position in the position which overlaps with the said airbag in a direction.
With the above-described configuration, the airbag can be suitably inflated toward the front side of the front side of the vehicle body by the arrangement of the guide of the force cloth and the skin tearing portion.
　このとき、前記パッド部材には、前記力布を前記表皮材側から前記ベース部材側に向かって挿通可能なパッド開口部が形成され、該パッド開口部と、前記力布係止溝とは、前記エアバッグに対して互いに車体幅方向の反対側に位置していると良い。
　上記構成により、表皮開裂部に一端側が取り付けられ、他端側が力布係止溝に係止されてパッド部材を覆っている力布について全長を短くでき、コンパクトに配置できる。
　具体的には、力布がパッド部材とエアバッグの間を通過するように配置されるとき、例えば、パッド開口部と力布係止溝がエアバッグに対して車体幅方向の同一側に設けられる場合と比較して、力布がパッド部材を覆う面積が大きくならず、力布の延ばし方も複雑にならなくて済む。 At this time, the pad member is formed with a pad opening through which the blanket can be inserted from the skin material side toward the base member side, and the pad opening and the blanket locking groove are: It is preferable that the airbags are positioned on opposite sides of the vehicle body width direction.
With the above-described configuration, the entire length of the webbing, in which one end side is attached to the skin cleaving portion and the other end side is locked by the webbing locking groove and covers the pad member, can be arranged compactly.
Specifically, when the baffle is arranged so as to pass between the pad member and the airbag, for example, the pad opening and the baffle locking groove are provided on the same side in the vehicle body width direction with respect to the airbag. Compared to the case where the padding member is formed, the area where the padding covers the pad member is not increased, and the method of extending the padding does not have to be complicated.
　このとき、前記力布係止溝は、車体幅方向において前記エアバッグよりも前記後部座席側の位置に配置されていると良い。
　上記構成により、力布によって、エアバッグを車体前方側に安定して膨出させることができ、乗員が着座する後部座席側へのエアバッグ展開衝撃を抑制できる。
　理由として、エアバッグを格納するベース格納部の車体幅方向において、車外側は剛性の高い車体ドアに支持されている一方で、車内側は弾性の高い後部座席に支持されている。すると、エアバッグの膨出展開方向が、一般に車体幅方向において弾性の高い後部座席側に引き寄せられる傾向となる。
　そこで、後部座席側の位置に力布係止溝を設けて、後部座席側を力布によって優先的にガイドすれば、エアバッグの膨出展開方向が安定するためである。 At this time, the baffle locking groove may be disposed at a position closer to the rear seat than the airbag in the vehicle width direction.
With the above-described configuration, the airbag can be stably inflated to the front side of the vehicle body by the baffle, and the airbag deployment impact to the rear seat side where the occupant is seated can be suppressed.
As a reason, in the vehicle body width direction of the base storage portion for storing the airbag, the vehicle outer side is supported by a highly rigid vehicle body door, while the vehicle inner side is supported by a highly elastic rear seat. As a result, the airbag inflating and expanding direction tends to be drawn toward the rear seat side, which is generally highly elastic in the vehicle body width direction.
Therefore, if a baffle locking groove is provided at a position on the rear seat side and the rear seat side is preferentially guided by the baffle, the bulging and deploying direction of the airbag is stabilized.
　このとき、前記ベース格納部は、前記エアバッグ及び前記インフレータの車体後方側に配置される後壁部と、該後壁部の車体幅方向の両端部から連続して車体前方側に延びる第１側壁部及び第２側壁部と、を備え、前記力布係止溝は、前記第１側壁部に設けられ、前記インフレータには、該インフレータを前記ベース格納部に組み付けるための被組み付け部が設けられ、該被組み付け部は、前記第１側壁部とは異なる壁部に組み付けられていると良い。
　上記のように、力布係止溝は、ベース格納部において第１側壁部に設けられ、インフレータを組み付けるための被組み付け部は、第１側壁部とは異なる壁部に組み付けられているため、互いに干渉を抑制でき、力布及びインフレータの組み付け作業が効率化する。 At this time, the base storage portion includes a rear wall portion disposed on the vehicle body rear side of the airbag and the inflator, and a first extending continuously from the both end portions of the rear wall portion in the vehicle body width direction to the vehicle body front side. A side wall portion and a second side wall portion, wherein the baffle locking groove is provided in the first side wall portion, and the inflator is provided with an assembly portion for assembling the inflator to the base storage portion. The assembled part is preferably assembled to a wall part different from the first side wall part.
As described above, the baffle locking groove is provided in the first side wall portion in the base storage portion, and the assembled portion for assembling the inflator is assembled in a wall portion different from the first side wall portion. Interference can be suppressed, and the assembly work of the bundling and the inflator becomes efficient.
　このとき、前記表皮材は、一端側が各々前記表皮開裂部の位置で連結され、該表皮開裂部に対して前記車体側に配置されるアウタ表皮材と、前記後部座席側に配置されるインナ表皮材と、を備え、前記ベース部材には、車体幅方向の前記車体側に設けられ、前記アウタ表皮材の他端部を係止する係止爪と、車体幅方向の前記後部座席側に設けられ、前記インナ表皮材の他端部を木目込む木目込み溝と、が形成され、前記力布は、前記表皮材において前記インナ表皮材に一端側が取り付けられていると良い。
　上記のように、表皮材のうち、インナ表皮材側が木目込み溝に木目込まれ、アウタ表皮材側が係止爪で係止されているため、インナ表皮材がアウタ表皮材よりも比較的支持剛性が低くなる。そこで、インナ表皮材に力布を取り付けることで、インナ表皮材を補強することができ、表皮材全体の支持剛性が向上する。 At this time, one end side of each of the skin materials is connected at the position of the skin cleavage portion, and an outer skin material disposed on the vehicle body side with respect to the skin cleavage portion, and an inner skin disposed on the rear seat side. The base member is provided on the vehicle body side in the vehicle body width direction, and is provided on the rear seat side in the vehicle body width direction, and a locking claw for locking the other end portion of the outer skin material. And a grained groove for graining the other end of the inner skin material is formed, and one end side of the blanket is preferably attached to the inner skin material in the skin material.
As described above, because the inner skin material side of the skin material is grained into the wood groove and the outer skin material side is locked by the locking claws, the inner skin material has a relatively higher support rigidity than the outer skin material. Lower. Therefore, by attaching a power cloth to the inner skin material, the inner skin material can be reinforced, and the support rigidity of the entire skin material is improved.
　本発明によれば、リテーナ部材によって、ベース格納部周辺の剛性だけでなく、力布の取り付け剛性も向上する。
　また、エアバッグの膨出展開時にガス圧力が力布係止溝周辺に負荷された場合にも、力布の係止部材が、リテーナ部材の保持によって力布係止溝から抜けてしまうことを抑制できる。すなわち、力布の取り付けが安定する。

Can be suppressed. That is, the attachment of the bundling is stable.
Accordingly, the side airbag device is capable of stabilizing the bulging and deploying direction of the airbag toward the front side of the vehicle body.
Further, it is easy to attach and remove the locking member to the baffle locking groove.

In the corresponding position, a skin cleaving portion 61 that is cleaved when the airbag 10 is inflated is formed.
One end of the skin material 60 is connected at the position of the skin cleaving portion 61, an outer skin material 62 disposed on the vehicle outer side with respect to the skin cleaving portion 61, an inner skin material 63 disposed on the vehicle inner side, Consists mainly of.
　アウタ表皮材６２の車外側の他端部が、ベース外壁部２２の係止爪２２ａに上下方向にわたって係止されており、インナ表皮材６３の車内側の他端部がベース内壁部２３の木目込み溝２３ａに木目込まれている。
　具体的には、アウタ表皮材６２の他端部には、係止爪２２ａに係止させるための係止孔が上下方向にわたって形成されており、インナ表皮材６３の他端部には、木目込み溝２３ａに木目込むための皮革製のトリムコードが縫着されている。 The other end portion of the outer skin material 62 on the vehicle outer side is locked in the vertical direction to the locking claw 22 a of the base outer wall portion 22, and the other end portion of the inner skin material 63 on the vehicle inner side includes the grain of the base inner wall portion 23. Wood is embedded in the groove 23a.
Specifically, a locking hole for locking the locking claw 22a is formed in the other end portion of the outer skin material 62 in the vertical direction, and the other skin portion of the inner skin material 63 includes a grain. A leather trim cord is sewn into the groove 23a.
　上記構成において、図９に示すようにエアバッグ１０が膨出展開したときには、表皮材６０は、表皮開裂部６１を分岐点としてアウタ表皮材６２とインナ表皮材６３とに分かれて展開される。
　表皮開裂部６１は、車体幅方向においてエアバッグ１０に重なる位置に配置されている。 In the above configuration, when the airbag 10 is inflated and deployed as shown in FIG. 9, the skin material 60 is deployed by being divided into an outer skin material 62 and an inner skin material 63 with the skin cleaving portion 61 as a branch point.
The skin cleaving portion 61 is disposed at a position overlapping the airbag 10 in the vehicle body width direction.
　力布７０は、エアバッグ１０の膨出展開方向を車体前方側にガイドする布部材からなる。
　力布７０は、図６に示すように、表皮材６０の表皮開裂部６１に一端部７１が取り付けられ、一端部７１から連続してパッド部材５０を覆うように延びて、ベース格納部２４に設けられた力布係止溝２７に他端部７２が係止されている。 The force cloth 70 is made of a cloth member that guides the inflating and deploying direction of the airbag 10 to the front side of the vehicle body.
As shown in FIG. 6, the force cloth 70 has one end 71 attached to the skin cleaving portion 61 of the skin material 60, and extends continuously from the one end 71 so as to cover the pad member 50. The other end 72 is locked to the provided force cloth locking groove 27.
　具体的には、力布７０は、インナ表皮材６３側の表皮開裂部６１周辺に縫着された一端部７１から連続してインナパッド部材５０ｂの前面を沿うように車外側に延びて、パッド開口部５１に対向する部分まで到達している。
　そして、力布７０は、パッド開口部５１を通過してインナパッド部材５０ｂの車外側面及び背面を沿うように連続して延びて、ベース格納部２４の内側壁部２４ｃに設けられた挿通孔２９まで到達している。
　このとき、力布７０は、車体前後方向においてパッド部材５０とエアバッグ１０との間を通過するように延びている。 Specifically, the webbing 70 continuously extends from the one end portion 71 sewn around the skin cleaving portion 61 on the inner skin material 63 side to the vehicle outer side along the front surface of the inner pad member 50b. It reaches the portion facing the opening 51.
The webbing 70 passes through the pad opening 51 and continuously extends along the vehicle outer surface and the rear surface of the inner pad member 50b, and is inserted into the insertion hole 29 provided in the inner wall portion 24c of the base storage portion 24. Has reached.
At this time, the webbing 70 extends so as to pass between the pad member 50 and the airbag 10 in the longitudinal direction of the vehicle body.
　そして、力布７０は、挿通孔２９を通過して力布係止溝２７まで連続して延びて、力布係止溝２７に係止されている。
　このとき、力布７０の他端部７２には、力布係止溝２７に木目込むための係止部材７３と、係止部材７３よりも他端側に延出している力布延出部７４と、が設けられている。 The force cloth 70 passes through the insertion hole 29 and continuously extends to the force cloth locking groove 27 and is locked to the force cloth locking groove 27.
At this time, the other end portion 72 of the force cloth 70 has an engaging member 73 for entering the grain in the force cloth engaging groove 27 and a force cloth extending portion extending to the other end side from the engaging member 73. 74 is provided.
　係止部材７３は、略矩形板状からなる皮革製のトリムコードであって、図６～図８に示すように、力布７０の他端部７２に縫着され、力布係止溝２７に木目込まれる第１係止部材７３ａと、力布７０の他端側に縫着され、力布７０の延出方向において力布係止溝２７と挿通孔２９との間に配置される第２係止部材７３ｂと、から構成されている。 The locking member 73 is a leather trim cord having a substantially rectangular plate shape, and is sewn to the other end portion 72 of the force cloth 70 as shown in FIGS. The first locking member 73a to be grained and the second locking member 70 is sewn to the other end side of the force cloth 70, and is disposed between the force cloth locking groove 27 and the insertion hole 29 in the extending direction of the force cloth 70. 2 locking members 73b.
　第１係止部材７３ａは、図７に示すように、力布係止溝２７から一部張り出すようにして力布係止溝２７に木目込まれており、張り出し部分が車体後方側にあるリテーナ部材３０に向かって延びている。
　詳しく言うと、第１係止部材７３ａは、力布係止溝２７に木目込まれた状態で、木目込み方向の一端が力布係止溝２７の底壁部２７ａに力布７０を介して当接する配置となっている。また、木目込み方向の他端となる張り出し部分が、リテーナ部材３０の力布保持部３２に当接する配置となっている。
　また、第１係止部材７３ａは、力布係止溝２７の内部空間において力布７０に包まれるようにして木目込まれている。
　そのため、力布７０の取り付け強度が向上し、エアバッグ１０の膨出展開方向をガイドする力布７０のガイド性が向上する。 As shown in FIG. 7, the first locking member 73 a is grained into the force cloth locking groove 27 so as to partially protrude from the force cloth locking groove 27, and the protruding portion is on the rear side of the vehicle body. It extends toward the retainer member 30.
More specifically, the first locking member 73a is in a state in which the first locking member 73a is engraved in the baffle locking groove 27, and one end in the graining direction contacts the bottom wall portion 27a of the baffle locking groove 27 via the bundling 70. It is arranged to touch. Further, the overhanging portion that is the other end in the graining direction is disposed so as to abut on the webbing holding portion 32 of the retainer member 30.
Further, the first locking member 73 a is engraved so as to be wrapped in the webbing 70 in the internal space of the webbing locking groove 27.
Therefore, the attachment strength of the webbing 70 is improved, and the guideability of the webbing 70 that guides the bulging and deploying direction of the airbag 10 is improved.
　第１係止部材７３ａの厚みは、挿通孔２９の開口幅よりも小さくなっている。また、第１係止部材７３ａの長尺方向の幅は、力布７０の幅方向（力布７０の延出方向に直交する幅方向）において挿通孔２９の開口長さよりも小さくなっている。
　そのため、力布７０を挿通孔２９に挿通させるときに、第１係止部材７３ａを比較的容易に挿通孔２９に挿通させることができる。 The thickness of the first locking member 73 a is smaller than the opening width of the insertion hole 29. Further, the width of the first locking member 73a in the longitudinal direction is smaller than the opening length of the insertion hole 29 in the width direction of the webbing 70 (the width direction orthogonal to the extending direction of the webbing 70).
Therefore, the first locking member 73a can be inserted into the insertion hole 29 relatively easily when the force cloth 70 is inserted through the insertion hole 29.
　第２係止部材７３ｂは、図７に示すように、挿通孔２９の車体後方側に配置されており、詳しく言うと、車体前後方向において挿通孔２９周辺とリテーナ部材３０との間に挟まれ、かつ、車体幅方向において力布係止溝２７の側壁部２７ｂとリテーナ部材３０との間に挟まれるように配置されている。
　そのため、力布７０の取り付け強度が向上し、力布７０のガイド性が向上する。 As shown in FIG. 7, the second locking member 73 b is disposed on the vehicle body rear side of the insertion hole 29. More specifically, the second locking member 73 b is sandwiched between the periphery of the insertion hole 29 and the retainer member 30 in the longitudinal direction of the vehicle body. And it arrange | positions so that it may be pinched | interposed between the side wall part 27b and the retainer member 30 of the bedding locking groove 27 in the vehicle body width direction.
Therefore, the attachment strength of the webbing 70 is improved, and the guideability of the webbing 70 is improved.
　第２係止部材７３ｂの厚みは、挿通孔２９の開口幅よりも小さくなっている。一方で、第２係止部材７３ｂの長尺方向の幅は、力布７０の幅方向において挿通孔２９の開口長さよりも大きくなっている。
　すなわち、力布７０が組み付けられた状態のとき、第２係止部材７３ｂは、挿通孔２９から比較的容易に抜けることなく、挿通孔２９周辺に引掛かった状態で支持される。
　なお、第２係止部材７３ｂを挿通孔２９に挿通させるときには、力布７０の延出方向に対して第２係止部材７３ｂをやや傾けた状態にして挿通させると良い。 The thickness of the second locking member 73 b is smaller than the opening width of the insertion hole 29. On the other hand, the width in the longitudinal direction of the second locking member 73 b is larger than the opening length of the insertion hole 29 in the width direction of the webbing 70.
That is, when the force cloth 70 is assembled, the second locking member 73 b is supported in a state of being caught around the insertion hole 29 without being relatively easily removed from the insertion hole 29.
When the second locking member 73b is inserted through the insertion hole 29, the second locking member 73b may be inserted with the second locking member 73b slightly inclined with respect to the extending direction of the webbing 70.
　力布延出部７４は、力布７０の他端部７２から連続して延びている布部材であって、図８に示すように、力布７０の他端部７２よりも幅狭となるように一体的に形成されている。
　詳しく言うと、力布延出部７４の先端７４ａは、延出方向に沿って徐々に幅狭となるように略半円形状（半楕円形状）に形成されている。
　そのため、作業者が力布７０の他端部７２を引っ張って車体前方側から挿通孔２９に挿通させるときに、力布延出部７４を挿通孔２９に先に挿通させて車体後方側から引っ張ることで、力布７０の組み付け作業が向上する。 The force cloth extending portion 74 is a cloth member continuously extending from the other end portion 72 of the force cloth 70, and becomes narrower than the other end portion 72 of the force cloth 70, as shown in FIG. Are integrally formed.
More specifically, the tip 74a of the bundling extension portion 74 is formed in a substantially semicircular shape (semi-elliptical shape) so as to become gradually narrower along the extending direction.
Therefore, when the operator pulls the other end portion 72 of the force cloth 70 to be inserted into the insertion hole 29 from the front side of the vehicle body, the operator extends the force cloth extension portion 74 first through the insertion hole 29 and pulls it from the rear side of the vehicle body. Thus, the assembling work of the bundling 70 is improved.
　力布延出部７４の厚みは挿通孔２９の開口幅よりも小さくなっており、力布延出部７４の幅は挿通孔２９の開口長さよりも小さくなっている。
　また力布延出部７４の延出方向の全長は、挿通孔２９の孔方向の深さよりも大きくなっている。
　そのため、作業者が力布延出部７４を車体前方側から挿通孔２９に先に挿通させて、車体後方側から引っ張る作業が一層容易になる。その結果、力布７０の組み付け作業が格段に向上する。 The thickness of the force extending portion 74 is smaller than the opening width of the insertion hole 29, and the width of the force extending portion 74 is smaller than the opening length of the insertion hole 29.
The total length of the force extending portion 74 in the extending direction is larger than the depth of the insertion hole 29 in the hole direction.
Therefore, it becomes easier for the operator to insert the force-applying extension portion 74 first through the insertion hole 29 from the front side of the vehicle body and pull it from the rear side of the vehicle body. As a result, the assembling work of the bundling 70 is remarkably improved.
　上記構成において、図９に示すようにエアバッグ１０が膨出展開したときには、力布７０は、エアバッグ１０の膨出方向を表皮材６０の表皮開裂部６１側にガイドする。
　また、力布７０の一端部７１側は、インナパッド部材５０ｂ及びインナ表皮材６３と共に車体前後方向の前方側に展開され、また車体幅方向の車内側に展開されることになる。 In the above configuration, when the airbag 10 is inflated and deployed as shown in FIG. 9, the webbing 70 guides the direction of inflation of the airbag 10 toward the skin cleaving portion 61 side of the skin material 60.
Further, the one end 71 side of the force cloth 70 is deployed on the front side in the vehicle longitudinal direction together with the inner pad member 50b and the inner skin material 63, and is deployed on the vehicle inner side in the vehicle width direction.
　また上記構成において、エアバッグ１０が膨出展開したときには、力布７０の他端側に縫着された第２係止部材７３ｂが挿通孔２９周辺に引掛かった状態で支持される。
　そのため、第１係止部材７３ａが力布係止溝２７から抜けてしまうことを抑制でき、力布７０の取り付けが安定し、エアバッグ１０の膨出展開方向が安定する。 Further, in the above configuration, when the airbag 10 is inflated and deployed, the second locking member 73b sewn on the other end side of the webbing 70 is supported in a state of being hooked around the insertion hole 29.
Therefore, it can suppress that the 1st latching member 73a slips out from the bedding latching groove 27, the attachment of the bedding 70 is stabilized, and the expansion | deployment direction of the airbag 10 is stabilized.
　また上記構成において、エアバッグ１０が膨出展開したときには、力布７０の他端側にある力布延出部７４がベース格納部２４とリテーナ部材３０との間に挟まれて支持されているため、力布７０の取り付けを一層安定させることが可能となる。 In the above configuration, when the airbag 10 is inflated and deployed, the force cloth extending portion 74 on the other end side of the force cloth 70 is sandwiched and supported between the base storage portion 24 and the retainer member 30. Therefore, it is possible to further stabilize the attachment of the bundling 70.
　　＜サイドエアバッグ装置の第２実施形態＞
　次に、サイドエアバッグ装置Ｓの第２実施例について、図１０に基づいて説明する。
　なお、上述したサイドエアバッグ装置Ｓと重複する内容は説明を省略する。
　第２実施例に係るサイドエアバッグ装置Ｓでは、ベース格納部１２４において、インフレータ１１の組み付け軸部１３が外側壁部１２４ｂ側に組付けられる一方で、力布７０の他端部７２が、内側壁部１２４ｃ側にある力布係止溝１２７に係止されている構成が異なっている。
　また、外側壁部１２４ｂに設けられたベース穴部１２８と、内側壁部１２４ｃに設けられた力布係止溝１２７とは、上下方向において重ならない位置に配置されている。
　そして、ベース格納部１２４の背面には、エアバッグ１０及びインフレータ１１を車体後方側から保持するためのリテーナ部材１３０が装着されている。 <Second Embodiment of Side Airbag Device>
Next, a second embodiment of the side airbag device S will be described with reference to FIG.
In addition, the description which overlaps with the side airbag apparatus S mentioned above is abbreviate | omitted.
In the side airbag device S according to the second embodiment, in the base storage portion 124, the assembly shaft portion 13 of the inflator 11 is assembled on the outer wall portion 124b side, while the other end portion 72 of the baffle 70 is on the inner side. The structure locked in the force cloth locking groove 127 on the wall 124c side is different.
Further, the base hole portion 128 provided in the outer wall portion 124b and the bedding locking groove 127 provided in the inner wall portion 124c are arranged at positions that do not overlap in the vertical direction.
A retainer member 130 for holding the airbag 10 and the inflator 11 from the rear side of the vehicle body is mounted on the back surface of the base storage portion 124.
　上記構成により、ベース格納部１２４において、インフレータ１１が組み付けられるベース穴部１２８と、力布７０が係止される力布係止溝１２７とが異なる壁部に形成されているため、互いに干渉を抑制してコンパクトに配置できる。
　また、インフレータ１１の組み付け軸部１３が、インフレータ１１に対して車外側の位置に配置されており、比較的スペースを確保し易い位置となるため、省スペース化及び力布７０の組み付け作業の効率化を果たせる。 With the above configuration, in the base storage portion 124, the base hole portion 128 into which the inflator 11 is assembled and the force cloth locking groove 127 to which the force cloth 70 is locked are formed in different wall portions, so that they interfere with each other. Suppressing and compact arrangement.
Further, since the assembly shaft portion 13 of the inflator 11 is disposed at a position outside the vehicle with respect to the inflator 11 and becomes a position where it is relatively easy to secure a space, space saving and efficiency of assembling the bundling 70 are achieved. Can be realized.
　　＜サイドエアバッグ装置の第３実施形態＞
　次に、サイドエアバッグ装置Ｓの第３実施例について、図１１に基づいて説明する。
　第３実施例に係るサイドエアバッグ装置Ｓでは、第２実施例と比較して、ベース部材１２０と表皮材６０との間にパッド部材５０が載置されていない構成が異なっている。
　そのため、表皮材６０がベース部材１２０の前面に当接して配置されており、また、力布１７０がパッド部材５０を覆う必要がなくなって比較的短い長さで取り付けられている。 <Third Embodiment of Side Airbag Device>
Next, a third embodiment of the side airbag device S will be described with reference to FIG.
The side airbag device S according to the third embodiment is different from the second embodiment in that the pad member 50 is not placed between the base member 120 and the skin material 60.
For this reason, the skin material 60 is disposed in contact with the front surface of the base member 120, and the bedding 170 does not need to cover the pad member 50 and is attached with a relatively short length.
　具体的には、力布１７０は、表皮材６０の表皮開裂部６１に一端部１７１が取り付けられ、一端部１７１から連続して膨出前のエアバッグ１０に沿わせてほぼ最短距離で延びて、ベース格納部１２４に設けられた力布係止溝１２７に他端部１７２が係止されている。
　また、力布１７０は、ベース格納部１２４においてエアバッグ１０及びインフレータ１１よりも車体幅方向の車内側に配置されている。 Specifically, the baffle 170 has one end portion 171 attached to the skin cleaving portion 61 of the skin material 60, and extends from the one end portion 171 continuously along the airbag 10 before inflating at a substantially shortest distance, The other end portion 172 is locked to the force cloth locking groove 127 provided in the base storage portion 124.
In addition, the force cloth 170 is disposed on the vehicle interior side in the vehicle body width direction with respect to the airbag 10 and the inflator 11 in the base storage portion 124.
　上記のように、パッド部材５０を不要にすることでサイドエアバッグ装置Ｓのコンパクト化を達成することができ、また、力布１７０の組み付け作業を一層簡素化することができる。 As described above, the side airbag device S can be made compact by making the pad member 50 unnecessary, and the assembling work of the bundling 170 can be further simplified.
　　＜その他の実施形態＞
　上記実施形態において、図４に示すように、力布係止溝２７は、力布７０の他端にある係止部材７３を木目込むための溝として形成されているが、溝に限定されることなく、力布７０の係止部材７３が係止可能であれば、貫通した係止孔、係止爪、又は係止凸部等でであっても良い。 <Other embodiments>
In the above embodiment, as shown in FIG. 4, the baffle locking groove 27 is formed as a groove for placing the locking member 73 at the other end of the buffing cloth 70, but is limited to the groove. Instead, as long as the locking member 73 of the webbing 70 can be locked, a penetrating locking hole, a locking claw, or a locking projection may be used.
　上記実施形態において、図６に示すように、力布係止溝２７は、ベース格納部２４において内側壁部２４ｃに設けられているが、これに限定されることなく、外側壁部２４ｂや後壁部２４ａに設けられても良いし、ベース部材２０上の所定位置に設けられても良い。
　ただし望ましくは、力布係止溝２７は、ベース格納部２４においてエアバッグ１０及びインフレータ１１よりも車体幅方向の車内側に形成されている方が良い。
　このようにすれば、力布７０によって、エアバッグ１０を車体前方側に一層安定して膨出展開できるためである。
　理由として、エアバッグ１０を格納するベース格納部２４の車体幅方向において、外側壁部２４ｂ側は、比較的剛性の高い車体ドア２ａに支持されている一方で、内側壁部２４ｃ側は、比較的弾性の高い後部座席１に支持されている。すると、エアバッグ１０の膨出展開方向が、車体幅方向において弾性の高い後部座席１側に引き寄せられる傾向となる。
　そこで、内側壁部２４ｃ側に力布係止溝２７を設けて、内側壁部２４ｃ側を力布７０によって優先的にガイドすれば、エアバッグ１０の膨出展開方向が安定するからである。 In the above embodiment, as shown in FIG. 6, the baffle locking groove 27 is provided in the inner wall portion 24 c in the base storage portion 24, but is not limited thereto, and the outer wall portion 24 b and the rear wall portion 24 c are not limited thereto. It may be provided on the wall portion 24 a or may be provided at a predetermined position on the base member 20.
However, it is preferable that the baffle locking groove 27 is formed on the vehicle interior side in the vehicle body width direction in the base storage portion 24 rather than the airbag 10 and the inflator 11.
This is because the airbag 10 can be more stably inflated and deployed to the front side of the vehicle body by the force cloth 70.
As a reason, in the vehicle body width direction of the base storage portion 24 for storing the airbag 10, the outer wall portion 24b side is supported by the relatively rigid vehicle body door 2a, while the inner wall portion 24c side is compared. It is supported by the rear seat 1 having high elastic elasticity. Then, the bulging and deploying direction of the airbag 10 tends to be drawn toward the rear seat 1 side having high elasticity in the vehicle body width direction.
Therefore, if the bedding locking groove 27 is provided on the inner wall portion 24c side and the inner wall portion 24c side is preferentially guided by the bedding 70, the bulging and deploying direction of the airbag 10 is stabilized.
　また上記実施形態において、図４に示すように、インフレータ１１の組み付け軸部１３は、ベース格納部２４において内側壁部２４ｃに組み付けられているが、これに限定されることなく、外側壁部２４ｂや後壁部２４ａに組み付けられていても良い。
　ただし望ましくは、組み付け軸部１３は、車体幅方向においてベース格納部２４の内側壁部２４ｃ側に組み付けられている方が良い。
　このようにすれば、ベース格納部２４の内側壁部２４ｃ側の支持剛性が向上するため、上記で説明したように、エアバッグ１０の膨出展開方向が安定するからである。 Moreover, in the said embodiment, as shown in FIG. 4, although the assembly | attachment axial part 13 of the inflator 11 is assembled | attached to the inner wall part 24c in the base storage part 24, it is not limited to this, The outer wall part 24b Or may be assembled to the rear wall 24a.
However, preferably, the assembly shaft portion 13 is preferably assembled to the inner wall portion 24c side of the base storage portion 24 in the vehicle body width direction.
This is because the support rigidity on the inner wall portion 24c side of the base storage portion 24 is improved, so that the inflation and deployment direction of the airbag 10 is stabilized as described above.
　また上記実施形態において、力布７０は布材料から形成されているが、布材料以外にも皮革材料や樹脂材料等の比較的弾性の高い公知な材料をガイド部材として採用可能である。 In the above embodiment, the force cloth 70 is formed of a cloth material, but a known material having relatively high elasticity such as a leather material or a resin material can be used as the guide member in addition to the cloth material.
　また上記実施形態において、係止部材７３は、皮革製のトリムコードとして形成されているが、樹脂製であっても良いし、力布係止溝２７に木目込み可能であれば公知な部材を採用可能である。 In the above embodiment, the locking member 73 is formed as a leather trim cord. However, the locking member 73 may be made of resin, or a known member may be used as long as it can be textured into the baffle locking groove 27. Is possible.
　また上記実施形態において、図６、図７に示すように、第１係止部材７３ａは、エアバッグ１０が膨出展開する前の通常状態のときに、力布係止溝２７に木目込まれた状態で、リテーナ部材３０に当接する配置となっているが、リテーナ部材３０との間に所定の間隔を空けて配置されていても良い。
　例えば、エアバッグ１０の膨出展開に伴ってガス圧力が負荷されて、第１係止部材７３ａが力布係止溝２７から抜ける方向に移動したときに、リテーナ部材３０に当接するような配置にしても良い。 Moreover, in the said embodiment, as shown in FIG. 6, FIG. 7, the 1st latching member 73a is put in the cloth cloth latching groove 27 at the time of the normal state before the airbag 10 inflates and expands. However, the retainer member 30 may be disposed at a predetermined interval from the retainer member 30.
For example, the gas pressure is applied as the airbag 10 is inflated and deployed, and the first locking member 73a is disposed so as to come into contact with the retainer member 30 when moving in the direction of coming out of the forceps locking groove 27. Anyway.
　また上記実施形態において、図８に示すように、第２係止部材７３ｂの長尺方向の幅は、挿通孔２９の開口長さよりも大きくなっているが、必ずしも幅広となっていなくても良い。
　形状を問わず、第２係止部材７３ｂが、力布の延出方向において力布係止溝２７と挿通孔２９との間に配置されていれば、従来と比較して力布の組み付け作業が容易になる。 Moreover, in the said embodiment, as shown in FIG. 8, although the width | variety of the elongate direction of the 2nd locking member 73b is larger than the opening length of the insertion hole 29, it does not necessarily need to be wide. .
Regardless of the shape, as long as the second locking member 73b is disposed between the force cloth locking groove 27 and the insertion hole 29 in the extending direction of the power cloth, the assembling work of the power cloth is compared with the conventional case. Becomes easier.
　また上記実施形態において、図８に示すように、第１係止部材７３ａ及び第２係止部材７３ｂの長尺方向の幅は、それぞれ力布７０の他端部７２の幅よりも広くなっており、かつ、第１係止部材７３ａの長尺方向の幅は第２係止部材７３ｂの幅よりも狭くなっているが、これに限定されることなく適宜変更可能である。
　例えば、図１２に示すように、第１係止部材７３ａ及び第２係止部材７３ｂの長尺方向の幅は略同一であっても良い。
