Description

  The present invention relates to a roof side module of a curtain airbag disposed on a roof side of a vehicle.

  In recent years, many automobiles equipped with curtain airbags have been used for the purpose of protecting passengers during side collisions. The curtain airbag is arranged along the shape of the roof side in a state of extending in the front-rear direction of the automobile beyond the center pillar on the vehicle body side portion side of the automobile.

  When it is detected that a rear-end collision or rollover has occurred from the side of the vehicle, or when these occurrences are predicted, the inflator gas is injected into the airbag, and the curtain airbag is inflated and deployed. Do. At this time, as the curtain airbag is inflated and deployed, the lower end of the roof side garnish (the door side of the roof side garnish) is pushed open upward in the vehicle interior, and the curtain airbag passes through the opened opening. Developed in a curtain shape downward. The occupant's head can be protected by the inflated and deployed curtain airbag.

  As the attachment structure for attaching the curtain airbag to the roof side, the attachment structure described in the head protection airbag device of Patent Document 1, the collision airbag device of Patent Document 2, and the passenger's head of Patent Document 3 In the protective device, a mounting structure and the like disclosed respectively have been proposed.

  In the head protection airbag device described in Patent Document 1, a curtain airbag and a roof side garnish (described as an airbag cover in Patent Document 1) are mounted on the roof side at a time. It is configured to be attached.

  For this reason, the curtain airbag cannot be attached to the roof side unless it is supported in a state along the shape of the roof side so that the curtain airbag can be attached to the roof side. The work was difficult.

  In order to solve this problem, Patent Document 2 and Patent Document 3 propose a module structure in which a curtain airbag is housed between a back cover member and a roof side garnish. By constructing the curtain airbag in a modular structure, the curtain airbag can be easily attached.

  In the airbag apparatus for collision described in Patent Document 2, the roof side garnish has a substantially linear shape with respect to the longitudinal direction. Since it is configured in this way, when the roof side garnish is expanded, the door side of the roof side garnish can be expanded around the thin hinge portion formed along the longitudinal direction of the roof side garnish. It is configured to be easy.

Moreover, in the structure of the roof side garnish in the occupant's head protection device described in Patent Document 3, the longitudinally extending curved portions are provided on the front end side and the rear end side of the roof side garnish in the longitudinal direction. It has a configuration with.

  Even if the airbag apparatus for collision described in Patent Document 2 is applied as it is to a vehicle having a curved portion in the front-rear direction of the roof side, the roof is configured to be substantially linear with respect to the longitudinal direction. In the side garnish, it is difficult to dispose so as to cover two curved portions.

  Therefore, as in the head protection airbag device described in Japanese Patent Application Laid-Open No. 2005-14629, if the roof side garnish is divided into two parts before and after in the longitudinal direction, it is described in Patent Document 2. The collision airbag device can be disposed on a vehicle having a curved portion in the front-rear direction of the roof side.

  However, the roof side garnish divided into two parts is exposed in the vehicle interior, resulting in poor appearance in the vehicle interior and a problem in design. Although it may be possible to make the contact portion where the two split roof side garnishes contact each other inconspicuously, even in that case, high processing accuracy and mounting accuracy of the roof side garnish are required. It will be. In addition, it takes a long time to attach the curtain airbag, and the manufacturing unit price of the vehicle increases.

  The occupant's head protecting device described in Patent Document 3 has a configuration in which curved portions extending in the longitudinal direction are provided on the front end portion side and the rear end portion side of the roof side garnish. Since it is comprised in this way, the curtain airbag described in patent document 3 is applicable with respect to the vehicle which has a curved part in the front-back direction of a roof side.

  However, when the door side of the roof side garnish is expanded around the thin hinge portion formed along the longitudinal direction of the roof side garnish, the expansion of the door side on the curved portion is hindered. become.

  That is, if the door side of the roof side garnish is to be expanded as it is with the hinge portion as the center, if the door portion side cannot be greatly expanded in the longitudinal direction as compared with the state before the expansion, The door side cannot be expanded toward the outward side. For this reason, when it is going to expand the door part side of a roof side garnish in the said curved part, a big gap will be produced in the behavior of a roof side garnish and the expansion of the door part side in the said curved part will be prevented. It will be.

  A solution to this problem is not disclosed in Patent Document 3, but when the curtain airbag is inflated and deployed, the front side and the rear side of the curved part of the roof side garnish in Patent Document 3 are not provided. The non-inflatable part of the curtain airbag is deployed. And in the site | part between the curved parts comprised substantially linearly, it becomes the structure which the expansion | swelling part of a curtain airbag expand | deploys.

  With this configuration, even if the door side of the roof side garnish does not greatly expand in the curved portion, the non-inflatable portion of the curtain airbag can be deployed from there, and the curtain airbag is inflated and deployed. It can be thought that it can be made. However, even in this case, since the degree of expansion on the door side of the roof side garnish in the curved portion remains narrow, it is not possible to greatly inflate the inflated portion of the curtain airbag between the curved portions. It is considered difficult.

  By the way, when the curtain airbag is inflated and deployed at a low temperature, a large gap is generated in the behavior of the roof side garnish between the state where the roof side garnish should be inflated and the state where the roof side garnish cannot be inflated. Due to this large gap, it is necessary to adjust the amount of deformation by reducing the thickness of the portion that is difficult to be deformed at a low temperature even though it is a portion that must expand.

  Further, as a configuration of the roof side garnish fixed to the roof side, in a portion not configured to be deformable with a degree of freedom, that is, a portion configured not to be deformed into a rigid body, a curtain airbag The reaction force accompanying the expansion of can not be absorbed by deformation at the same site. In such a part, it was necessary to select a material having a large bending elasticity.

  In the present invention, these problems in the prior art can be solved, the occurrence of cracks in the roof side garnish can be prevented, and the door side of the roof side garnish can be smoothly expanded, An object of the present invention is to provide a roof side module of a curtain airbag that can be effectively applied to a vehicle having a curved portion in the front-rear direction of the roof side.

The object of the present invention can be achieved by the inventions described in claims 1 to 4.
That is, in the present invention, a curtain airbag disposed on the roof side, a back cover member of the curtain airbag, a roof side garnish covering the curtain airbag and disposed on the vehicle interior side, and the roof side In the roof side module of the curtain airbag, in which the base bracket for installation is configured as a subassembly,
The door of the roof side garnish is configured to be able to expand around a thin hinge formed along the longitudinal direction of the roof side garnish, and the impact applied to the roof side garnish when the curtain airbag is deployed The most important feature is that an energy absorbing part that relaxes energy and smoothly expands on the door side of the roof side garnish is formed at a portion of the roof side garnish along the hinge part. There is no.

In the present invention, the main feature is that the energy absorption part is a long hole formed along the hinge part.
Further, in the present invention, the curtain airbag module has a curved portion extending in the longitudinal direction thereof, and the long hole is formed along the curved portion in the roof side garnish. ing.

  Furthermore, in the present invention, when the roof side garnish is expanded, the connecting member that connects the door side of the roof side garnish that becomes the expansion side and the attachment side of the roof side garnish that is fixed to the roof side. However, the main feature is that the long hole is formed or formed near the end of the long hole, and the connecting member has a member structure that does not prevent the roof side garnish from spreading. There is no.

  With the configuration of the roof side module of the curtain airbag according to the present invention, impact energy applied to the roof side garnish as the curtain airbag is inflated and deployed can be mitigated by the energy absorbing portion. And since the energy absorption part is formed in the site | part of the roof side garnish along the hinge part, the expansion in the door part side of a roof side garnish can be performed smoothly.

  In addition, the door side of the roof side garnish can be smoothly expanded even in an operating environment at low temperatures, the opening area of the expanded portion can be increased, and the curtain airbag can be inflated and deployed smoothly. be able to.

  In the present invention, the energy absorbing portion can be configured as a long hole formed along the hinge portion. By forming a long hole along the hinge portion, a long hole can be interposed between the door side of the roof side garnish and the attachment side of the roof side garnish. The roof side garnish is made of a synthetic resin material such as polycarbonate (PC), ABS, polypropylene, olefin-based thermoplastic elastomer, etc., so that even if the impact energy is applied, the roof side garnish sandwiches the long hole. The door side can be greatly deformed.

  Thereby, the opening area in the door part side of a roof side garnish can be expanded widely. Further, the impact energy applied to the roof side garnish as the curtain airbag is inflated and deployed can be absorbed when the vicinity of the long hole on the door side of the roof side garnish and the lower end side of the door are greatly deformed.

  Moreover, even if the vicinity of the long hole on the door side of the roof side garnish or the lower end side of the door is greatly deformed, the roof side garnish is not cracked. In addition, since the opening area on the door side of the roof side garnish can be opened large, the curtain airbag can be inflated and deployed sufficiently and uniformly downward.

  In the present invention, a long hole configured as an energy absorbing portion can be formed along the curved portion of the roof side garnish. With this configuration, the degree of expansion on the door side of the roof side garnish in the curved portion can be increased, and even if the roof side module is provided on the roof side having the curved portion, the roof side garnish of the curved portion is not provided. The opening area on the door side can be greatly opened.

  Moreover, by forming the roof side garnish with the synthetic resin material as described above, the effects brought about by the material constituting the roof side garnish can be exhibited synergistically. Thereby, the opening area in the door part side of the roof side garnish in a curved part can be opened more widely, and the expansion in the door part side of a roof side garnish can be performed smoothly. Moreover, even when the door side of the roof side garnish is expanded, the roof side garnish is not cracked.

  In the present invention, when the roof side garnish is expanded, the door side of the roof side garnish that is the expansion side and the attachment side of the roof side garnish that is fixed to the roof side are connected by a connecting member. be able to. Moreover, the connecting member can be disposed in the vicinity of the end of the elongated hole formed as an energy absorbing portion or in the vicinity of the end of the elongated hole, and the connecting member is a material that does not hinder the expansion of the roof side garnish. Or it can comprise by structure.

  By using the connecting member configured as described above, the door side of the roof side garnish can be smoothly expanded, and the door side of the roof side garnish is the attachment side of the roof side garnish. Can be prevented by the connecting member.

  As a material constituting the connecting member, a flexible material including an elastic body or the like can be used. Moreover, as a structure of a connection member, a thin groove | channel etc. can be formed with respect to a connection member so that the expansion in the door part side of a roof side garnish may not be prevented.

  Preferred embodiments of the present invention will be specifically described below with reference to the accompanying drawings. The configuration of the roof side module of the curtain airbag according to the present invention is not limited to the shape and arrangement described below. Even if it is a configuration other than those described below, if the configuration and configuration can solve the problems of the present invention, the configuration and configuration are adopted as the configuration of the roof side module of the curtain airbag of the present invention. can do. For this reason, this invention is not limited to the Example demonstrated below, A various change is possible.

  The configuration of the roof side module 1 according to the present invention will be described with reference to FIGS. A roof side module 1 shown in FIG. 1 constitutes a curtain airbag device together with a sensor part and a control part (not shown).

  The roof side module 1 is provided on the roof side 14 (see FIG. 3) on the side of the vehicle. When a sensor (not shown) detects the occurrence of a rear-end collision or rollover on the side of the vehicle, or when these occurrences are predicted by the control device, a detection signal from the sensor (not shown) or a control device (not shown) The inflator 12 operates according to the control signal. When the inflator 12 is operated to generate gas, the generated gas causes the curtain member 4b in the roof side module 1 to expand and deploy.

  The curtain member 4b is housed in the roof side module 1 in a state of being folded in a bellows shape, and is connected to the inflator 12 via the gas introduction member 13 as shown in the exploded view of FIG. . The curtain member 4b includes a plurality of support pieces 4a, and each support piece 4a is sandwiched between resin panels via an adhesive. The curtain airbag 4 is configured by the curtain member 4b, the inflator 12, and the like.

Then, the curtain airbag 4 can be attached to the back cover 3 by inserting the support pieces 4a formed on the curtain member 4b into the holding portions 3b formed on the back cover 3.
The back cover 3 is configured to be attached to the base bracket 2 through fixing means such as screws. A roof side garnish 7 that covers the curtain member 4b and the inflator 12 supported by the back cover 3 from the front side is attached to the base bracket 2 via an attachment pin 23 described later with reference to FIGS. . Further, the roof side garnish 7 integrally engages the roof side garnish 7 and the back cover 3 by engaging the engagement pieces 28a formed on the engagement portion 28 with the engagement holes 3c formed on the back cover 3. Can be configured.

  Then, the base side bracket 2, the back cover 3, the curtain airbag 4 and the roof side garnish 7 shown in FIG. 2 are integrally assembled to constitute the roof side module 1 shown in FIG. Thus, since the curtain airbag 4 is housed in the roof side module 1, the curtain airbag 4 can be easily disposed in the vehicle interior simply by attaching the base bracket 2 to the roof side 14.

  Moreover, the roof side module 1 can be configured as a structure that is compact and has a predetermined rigidity. For this reason, in the process of attaching the roof side module 1 to the roof side 14, the attaching operation can be automated using the attaching robot.

  The configuration of the roof side module 1 shown in FIG. 1 will be described in further detail. The roof side module 1 has a curved portion formed at a portion indicated by reference numeral 18. The curved portion 18 of the roof side module 1 is configured corresponding to the shape of the roof side 14 to which the roof side module 1 is attached. When the roof side module 1 according to the present invention is disposed on the roof side in which curved portions are formed on the front side and the rear side of the roof side, both the curves formed on the roof side are arranged. The curved portion 18 can also be formed on the front side and the rear side of the roof side module 1 so as to cover the portion.

  The curved portion 18 of the roof side garnish 7 is provided with a long hole 8a as an energy absorbing portion so that the door portion 7a side of the roof side garnish 7 at the curved portion 18 can be easily expanded as will be described later. I can keep it.

  As shown in FIGS. 1 and 2, the back cover 3 is provided with a pair of flange portions 17, and the flange portion 17 is configured as an attachment portion for attaching an assist grip (not shown). An assist grip (not shown) can be attached to the vehicle interior via the engagement hole 3a formed in the flange portion 17 and the attachment hole 2a formed in the base bracket 2.

  3 and 5 are cross-sectional views of the roof side module 1 showing a state in which the base bracket 2 is attached to the inner panel 16 of the roof side 14 via bolts 25a and nuts 25b. FIG. 3 schematically shows a state before the curtain airbag 4 is inflated and deployed, and FIG. 5 schematically shows a state where the curtain airbag 4 is inflated and deployed from the state of FIG. 3. .

  As shown in FIGS. 3 and 5, the curtain airbag 4 is housed in a space formed between the back cover 3 and the door 7 a of the roof side garnish 7. The surface side of the roof side garnish 7 opposite to the surface storing the curtain airbag 4 is the vehicle interior side. Although not shown in FIGS. 3 and 5, the curtain airbag 4 is supported by the back cover 3, and the back cover 3 and the roof side garnish 7 are attached to the base bracket 2.

  A hinge portion 10 is formed on the attachment portion 7b of the roof side garnish 7, and the hinge portion 10 has a groove shape extending in a direction perpendicular to the paper surface of FIG. 3 along the longitudinal direction of the roof side garnish 7. It is configured. As shown in FIG. 5, the door portion 7a of the roof side garnish 7 can be rotated upward about the hinge portion 10 as the curtain airbag 4 is inflated and deployed. That is, the lower part of the door part 7a of the roof side garnish 7 can be expanded around the hinge part 10, and the curtain member 4b can be expanded and deployed from the expanded opening.

  A connecting plate 20 as a connecting member is disposed between the door portion 7a and the attaching portion 7b of the roof side garnish 7, and the connecting plate 20 is connected to the door portion of the roof side garnish 7 via an attaching pin 23. 7a and the mounting portion 7b are arranged so as to be connected. The connection plate 20 shown in FIGS. 3 and 5 shows a configuration example arranged near the end of the long hole 8a described later with reference to FIGS. If there is a portion in the roof side garnish 7 where a crack or the like is likely to occur in the hinge portion 10 when the 4b is inflated and deployed, the connecting plate 20 can be disposed in the portion. Further, the connecting plate 20 can be disposed in a state of straddling the long hole 8a.

  The connecting plate 20 can be configured in a shape having a flexible member such as an elastic body or cloth, or a cut groove parallel to the hinge portion 10. As shown in FIG. 5, when the curtain airbag 4 is inflated and deployed, the connecting plate 20 is configured so as to allow the door portion 7a to rotate upward with the hinge portion 10 as the rotation center. I can keep it.

  4 schematically shows a cross-sectional view of the curved portion 18 of the roof side module 1. FIG. 6 shows a state in which the curtain airbag 4 is not expanded and deployed from the state shown in FIG. The state which expanded and expanded is shown typically. As shown in FIGS. 1 and 4, a long hole 8 a as an energy absorbing portion is formed along the hinge portion 10 in the curved portion 18 of the roof side module 1. The attachment portion 7b of the roof side garnish 7 is attached to the base bracket 2 via an attachment pin 24.

  7 (a) and 7 (b) show partial perspective views of the curved portion 18 of the roof side module 1, and FIG. 7 (a) shows a state before the curtain airbag 4 is inflated and deployed. FIG. 7B schematically shows a state where the curtain airbag 4 is inflated and deployed. As shown in FIGS. 7A and 7B, a connecting plate 20 as a connecting member is disposed between the door portion 7 a and the attaching portion 7 b of the roof side garnish 7. The connecting plate 20 may be disposed in the vicinity of both end portions of the long hole 8a or in a form of bridging the long hole 8a.

  4 and 7A, when the insulator 12 is operated and the curtain airbag 4 is inflated and deployed, the impact energy associated with the inflation and deployment of the curtain airbag 4 is applied to the door 7a of the roof side garnish 7. Acting on the side of the part 7a, the door part 7a is pivoted upward with the hinge part 10 as the pivot center. When the curtain airbag 4 is inflated and deployed, the impact energy associated with the inflation and deployment also acts on the back cover 3, but the back cover 3 is supported and fixed to the base bracket 2, so the impact energy at the time of inflation and deployment Most of this will act on the door portion 7a.

  Due to the impact energy acting on the door portion 7a, the door portion 7a rotates upward about the hinge portion 10 as a rotation center. Further, in the curved portion 18 of the roof side module 1, a long hole 8a is formed so that the door portion 7a can be easily rotated upward with the hinge portion 10 as a rotation center. With the long hole 8a, as shown in FIG. 7B, the door portion 7a can be deformed so as to expand toward the vehicle interior side while deforming the shape of the long hole 8a.

  In particular, the roof side garnish is made of synthetic resin such as polycarbonate (PC), ABS, polypropylene, olefinic thermoplastic elastomer, etc., so that the roof side garnish sandwiches the long hole 8a even when the impact energy is applied. The door portion 7a side of 7 can be greatly deformed.

Further, as shown in FIGS. 7 (a) and 7 (b), by forming an open portion 29 by cutting the lower end portion side of the door portion 7a, the door portion 7a can be smoothly expanded on the lower end portion side. The curtain member 4b can be easily deployed in a curtain shape downward from the lower end side of the expanded door portion 7a.
Further, as the door portion 7a expands and deforms, the portion that is formed thin in the portion that connects the door portion 7a and the mounting portion 7b as shown in FIG. 6 can be broken. it can.

  Such expansion and deformation of the door portion 7a, and breaking the thin-walled connecting portion between the door portion 7a and the mounting portion 7b, greatly opening the lower end side of the door portion 7a even in the curved portion 18. be able to. In addition, the impact energy can be absorbed so that the roof side garnish 7 is not damaged by the expansion deformation of the door portion 7a and the breakage of the thin connecting portion between the door portion 7a and the mounting portion 7b.

  Even if the thin connection portion between the door portion 7a and the attachment portion 7b is broken, the connection plate 20 is disposed at the portion where the elongated hole 8a is formed or the portion near the end of the elongated hole 8a. Therefore, it is possible to prevent the door portion 7a from being completely separated from the attachment portion 7b and hanging down.

  Moreover, since the connecting plate 20 can be configured with a member or a structure that does not prevent the upward rotation of the door portion 7a as described above, the lower end of the door portion 7a including the curved portion 18 is provided. It does not prevent the part side from opening greatly.

Since the roof side module 1 according to the present invention is configured as described above, when the inflator 12 is operated and gas is emitted, the curtain member 4b can be uniformly and rapidly expanded and deployed.
In addition, although the example which formed the hinge part 10 in the upper part side of the roof side garnish 7 was demonstrated, when it demonstrates using Fig.7 (a), the hinge part 10 is the side part part side of the roof side garnish 7. The hinge portion 10 can also be formed at the height position of the middle portion of the door portion 7a. If the hinge part 10 is formed on the upper side of the roof side garnish 7, it is difficult to visually recognize the long hole 8a from the interior of the vehicle interior, which is preferable from the viewpoint of design.

  FIGS. 8A and 8B show partial perspective views of the curved portion 18 of the roof side module 1 according to the second embodiment of the present invention. FIG. 8A shows a curtain airbag. 4 shows a state before the inflation and deployment, and FIG. 8B shows a state where the curtain airbag 4 is inflated and deployed.

  In the second embodiment, as a configuration example of the connecting plate 21 disposed in the vicinity of the end of the long hole 8a formed in the curved portion 18, a configuration in which a groove 22 parallel to the hinge portion 10 is formed is used. The configuration other than the connecting plate 21 having the groove 22 is the same as the configuration in the first embodiment. Therefore, in Example 2, about the structure similar to Example 1, the description is abbreviate | omitted by using the same member code | symbol as the member code | symbol used in Example 1. FIG.

  As shown in FIG. 8A, a groove 22 parallel to the hinge portion 10 is formed on the upper surface of the connecting plate 21. Both side surfaces of the groove 22 constituting the groove 22 function as contact portions 22a that contact each other when the door portion 7a is rotated upward, and as shown in FIG. Can be regulated. As a result, the lower end portion side of the door portion 7a can be opened by a predetermined amount, and the door portion 7a can be prevented from being pivoted upward so as to increase the opening area more than necessary. . Therefore, the gas emitted by the inflator 12 can be effectively used for the expansion and deployment of the curtain member 4b, and the expansion and deployment of the curtain member 4b can be performed smoothly and quickly.

  The technical idea of the present invention can be applied to other configurations of airbags.
