Description

  The present invention relates to an airbag-equipped vehicle in which an airbag is disposed along a roof side rail, and particularly to a locking structure for a roof lining terminal portion and a pillar garnish covering an airbag storage portion.

As a vehicle airbag, a so-called curtain airbag is known in which a bag body is deployed in a curtain shape between a vehicle body side wall and an occupant in the event of a vehicle collision or rollover, and the occupant's temporal region is protected by the bag body. It has been.
This airbag is stored from the front pillar to the roof side rail in a folded state, and high-pressure gas is introduced into the bag body at the time of a vehicle collision or the like so that the bag body is deployed in the vehicle interior. It has become. The bag body is disposed in a groove-shaped storage portion provided along the front pillar and the roof side rail, and an opening on the vehicle interior side of the storage portion is covered by a roof lining terminal portion.

  By the way, in a vehicle having a center pillar, an upper end portion of the center pillar is joined to a substantially central portion of the roof side rail, and a pillar garnish is attached to the vehicle interior side of the center pillar. For this reason, when mounting the above-described airbag on this type of vehicle, an airbag storage portion is provided on the roof side rail so as to straddle the connection portion with the center pillar, and the terminal portion of the roof lining is connected to the pillar garnish. It must be connected to the exposed side of the car without any steps.

As a roof lining locking structure to cope with this, an upper bent wall that is bent outwardly from the passenger compartment is extended to the upper end of the vertical wall of the pillar garnish, and an L-shaped roof lining is formed at the bent corner of the upper bent wall. A locking claw projecting upward at the upper end of the vertical wall of the pillar garnish, with the end part butted and locked, and the end of the roof lining was inserted into the back side of the locking claw Things have been devised. (For example, refer to Patent Document 1).
In any of these structures, when the airbag is deployed, the end portion of the roof lining is released from the locking portion by the gas pressure, thereby releasing the airbag storage portion.
Japanese Patent No. 3137588

  However, in the case of the former locking structure in which the L-shaped end of the roof lining is abutted against the upper bent wall on the pillar garnish side, slight manufacturing errors and assembly errors of components such as roof lining and pillar garnish Therefore, it is easy to create a gap between the two, and much labor is required to eliminate this gap.

  In addition, in the case of the latter locking structure in which the roof lining end is inserted into the back side of the locking claw on the pillar garnish side, the roof is configured to receive the input load at a substantially right angle on the flat surface on the back side of the locking claw. Since the terminal portion of the lining is locked by the locking claw, the deployment load acts on the locking claw as a load in the bending direction at the initial stage of deployment of the airbag. For this reason, a difficult design for avoiding breakage of the locking claws is forced.

  Therefore, the present invention makes it possible to easily match the roof lining end portion, which is released when the airbag is deployed, with the pillar garnish without any gaps, which makes it difficult to design, manufacture, and reduce assembly workability. It is an object of the present invention to provide a roof lining locking structure for a vehicle equipped with an air bag, which can reliably improve the appearance quality without incurring any problems.

  As means for solving the above-mentioned problems, the invention according to claim 1 is directed to a pillar (for example, a center pillar in an embodiment described later) on the vehicle interior side of a roof side rail (for example, roof lining 6 in an embodiment described later). 3) An air bag storage portion (for example, an air bag storage portion 4 in an embodiment described later) is provided so as to straddle the joint portion of 3), and a pillar garnish (for example, in an embodiment described later) that covers the interior side of the pillar. An upper bent wall (for example, an upper bent wall 10 in an embodiment described later) that extends toward the outside of the passenger compartment extends from the upper end of a vertical wall (for example, a vertical wall 9 in the embodiment described later) of the pillar garnish 8). And a roof lining terminal portion (for example, a terminal portion 7 in an embodiment described later) covering the vehicle interior side of the airbag storage portion In a roof lining locking structure for a vehicle equipped with an air bag that is locked to the pillar garnish so that the vehicle interior side exposed surfaces are substantially continuous, the upper bent wall of the pillar garnish is substantially perpendicular to the vertical wall of the pillar garnish. A base surface (for example, a first base surface 12 in an embodiment described later) and a first support surface (for example, a first support surface in an embodiment described later) rising above the base surface at a vehicle interior side position. 14) and a second support surface (for example, a second support surface 15 in an embodiment to be described later) that rises upward at a position outside the passenger compartment from the base surface, while curving the end portion of the roof lining. The terminal portion is contact-supported by a plurality of support surfaces on the upper bent wall including at least the first and second support surfaces.

  In the case of this invention, the terminal part of the curved roof lining is contact-supported by the several support surface of the upper bending wall of a pillar garnish. At this time, the terminal portion of the roof lining is supported by the first support surface on the vehicle interior side and the second support surface on the vehicle exterior side with at least the base surface of the upper bent wall interposed therebetween. It will be inserted between the first support surface and the second support surface. For this reason, even if a slight deviation occurs between the two due to manufacturing errors or assembly errors between the pillar garnish and roof lining, the deviation can be absorbed by the insertion structure between the two. Further, on the pillar garnish side, the roof lining locking load can be dispersed by a plurality of support surfaces, and therefore, stress concentration during airbag deployment can be prevented.

  According to a second aspect of the present invention, an airbag storage portion is provided on the vehicle interior side of the roof side rail so as to straddle the joint portion of the pillar, and the vertical wall of the pillar garnish covering the vehicle interior side of the pillar is provided. An upper bent wall that extends toward the outside of the passenger compartment extends from the upper end, and a roof lining terminal that covers the interior of the airbag housing part is substantially continuous with the exposed side of the passenger compartment side of the pillar garnish. In the roof lining locking structure for an airbag-equipped vehicle that is locked as described above, a concave curved support surface (for example, the curved support surface 30 in an embodiment described later) is provided on the upper surface side of the upper bent wall of the pillar garnish. And forming a curved portion of the roof lining to have a radius of curvature larger than the radius of curvature of the curved support surface. And so as to multi-point supported by the curved support surface of the bending wall.

  In the case of the present invention, the curved roof lining terminal portion is supported at multiple points by the curved support surface of the upper bent wall of the pillar garnish. At this time, since the radius of curvature of the end portion of the roof lining is set to be larger than the radius of curvature of the curved support surface on the pillar garnish side, the end portion of the roof lining is inserted in pressure contact with the curved support surface on the pillar garnish side. Become a form. For this reason, even if a misalignment between the two due to a manufacturing error or an assembly error of the pillar garnish and roof lining occurs, the misalignment can be absorbed by the insertion structure of both. In addition, since the end portion of the roof lining is supported at multiple points on the curved support surface, it is difficult for stress concentration to occur on the upper bent wall of the pillar garnish.

According to a third aspect of the present invention, in the first or second aspect of the present invention, the upper bent wall is brought into contact with a set position of a terminal portion of the roof lining, and the vehicle body front-rear position of the terminal portion is locked. A positioning locking portion (for example, a reinforcing rib 20 in an embodiment described later) is provided.
In this case, it is possible to easily position the roof lining in the longitudinal direction of the vehicle body during assembly by the positioning locking portion, and it is also possible to prevent the displacement of the roof lining in the vehicle longitudinal direction.

According to a fourth aspect of the present invention, in the third aspect of the present invention, a reinforcing rib (for example, a reinforcing rib 20 in an embodiment described later) that extends in the vehicle width direction is integrally formed on the upper surface side of the upper bent wall. This reinforcing rib was used as the positioning locking portion.
In this case, since the upper bent wall is reinforced by the reinforcing rib and the reinforcing rib is used as a positioning locking portion, the strength of the upper bent wall is improved without increasing the number of parts, and the vehicle width direction of the roof lining is increased. It becomes possible to perform positioning.

The invention according to claim 5 is the invention according to any one of claims 1 to 4, wherein a sinking width (for example, a sinking width W0 in an embodiment to be described later) of the roof lining to the upper bent wall side. W2) is continuously changed in the longitudinal direction of the vehicle body.
In this case, the locking force of the terminal portion increases or decreases according to the depth of penetration of the terminal portion of the roof lining to the upper bent wall. For this reason, it becomes possible to suppress generation | occurrence | production of the excessive latching force in an upper bending wall which becomes obstructive at the time of expansion | deployment of an airbag by reducing gradually the penetration width of a terminal part to the vehicle body front-back direction. It is also possible to adjust the locking force at the upper bent wall by changing the change gradient of the sinking width of the terminal portion, thereby adjusting the deployment timing of the airbag into the vehicle interior.

According to the present invention, since the curved end portion of the roof lining is locked in a manner of being inserted into the separated support portion on the upper bent wall, the relative relationship between the pillar garnish and the roof lining is obtained. The edge portion of the roof lining can be easily locked to the pillar garnish without a gap while absorbing the shift by the insertion portion.
In addition, the curved end of the roof lining is supported at multiple points on the upper bent wall of the pillar garnish, so stress concentration does not occur on the upper bent wall when the airbag is deployed, resulting in easy damage to the pillar garnish. In addition, it is possible to prevent it reliably.

Embodiments of the present invention will be described below with reference to the drawings. In the following description of each embodiment, the same parts are denoted by the same reference numerals, and the description of overlapping parts is omitted.
1 to 3 show a first embodiment of the present invention, and FIG. 2 is a schematic side view of a vehicle adopting a roof lining locking structure according to the present invention. FIG. 3 is a cross-sectional view corresponding to the AA cross section of FIG. 2, and FIG. 3 is a front view of portion B of FIG.

  In the vehicle shown in FIG. 2 to which the present invention is applied, the upper end of the center pillar 3 is joined to the roof side rail 2 that extends from the upper end of the front pillar 1 toward the rear of the vehicle body at the side of the vehicle body. On the vehicle interior side over the roof side rail 2, an airbag storage portion 4 (see FIG. 1) is provided so as to straddle the joint portion of the center pillar 3.

  As shown in FIG. 1, a bag body of an airbag 5 is stored in a folded state in the airbag storage portion 4, and the front surface on the vehicle interior side is covered with a terminal portion 7 on the side of the vehicle of the roof lining 6. .

  Further, a pillar garnish 8 is attached to the back side (vehicle compartment side) of the center pillar 3 as shown in FIGS. The pillar garnish 8 is provided with an upper bent wall 10 that extends toward the outside of the vehicle compartment at the upper end of the vertical wall 9 exposed to the vehicle interior side. The tip of the upper bent wall 10 is bent in an L shape upward, and the bent tip portion 11 is abutted near the joint between the roof side rail 2 and the center pillar 3. In this embodiment, the upper bent wall 10 of the pillar garnish 8 forms a part of the airbag housing portion 4, and the upper bent wall 10 covers the lower side of the airbag 5 installed on the vehicle body. Yes. The terminal portion 7 of the roof lining 6 is locked to the upper bent wall 10 of the pillar garnish 8, and in this state, the vehicle interior side exposed surfaces of the terminal portion 7 and the vertical wall 9 of the pillar garnish 8 are continuous with each other. Yes.

  Here, the upper bent wall 10 of the pillar garnish 8 has a first base surface 12 (base surface in the present invention) and a second base surface 13 which are substantially orthogonal to the vertical wall 9, and of these, the interior of the pillar garnish 8 is closer to the vehicle interior. The first base surface 12 arranged in a step is provided in a stepped manner with respect to the second base surface 13. A first support surface 14 that rises obliquely upward toward the vehicle interior side extends from the vehicle interior side position of the first base surface 12, and the vehicle exterior side position of the first base surface 12 A second support surface 15 that rises obliquely upward is extended. The first support surface 14 is continuous with the vertical wall 9 so as to form an acute angle upward with respect to the exposed surface on the vehicle interior side of the vertical wall 9. The second support surface 15 is continuous with the lower end of the orthogonal surface 16 that is substantially orthogonal to the second base surface 13.

  On the other hand, the terminal portion 7 of the roof lining 6 is formed thinner than the general portion of the roof lining 6, and the tip portion of the terminal portion 7 corresponding to the pillar garnish 8 is curved outward. The curved portion of the terminal portion 7 is inserted between the first support surface 14 and the second support surface 15 on the pillar garnish 8 side in the curved posture, and the engagement contact between the two surfaces 14 and 15 is performed. Due to this, it is locked to the upper bent wall 10 of the pillar garnish 8. The first support surface 14 and the second support surface 15 are arranged in a reverse C shape with the first base surface 12 interposed therebetween, but the curved portion of the terminal portion 7 of the roof lining 6 is The curvature is set such that the support surfaces 14 and 15 can always be in contact with each other.

As described above, in the roof lining locking structure of this vehicle, the curved portion of the terminal portion 7 of the roof lining 6 is inserted in a pressed state between the first support surface 14 and the second support surface 15 on the pillar garnish 8 side. Since it is inserted and locked, the displacement between the roof lining 6 and the pillar garnish 8 due to a manufacturing error or an assembly error can be flexibly absorbed by the insertion structure portion.
That is, even if the relative position of the roof lining 6 and the pillar garnish 8 is slightly shifted in the vehicle width direction or the vertical direction, in the case of this locking structure, the roof lining 6 with respect to the first and second support surfaces 14, 15. By adjusting the insertion state of the curved portion of the terminal portion 7, the terminal portion 7 can be reliably locked to the pillar garnish 8 without a gap.

  In particular, in the case of this embodiment, the first support surface 14 positioned on the vehicle interior side of the pillar garnish 8 is inclined obliquely upward so as to form an acute angle with the vehicle interior side exposed surface of the vertical wall 9 of the pillar garnish 8. Therefore, the clearance gap and level | step difference between the terminal part 7 of the roof lining 6 and the vertical wall 9 upper end can be restrained smaller.

  As described above, when this locking structure is employed, the error of each part can be absorbed by adjusting the insertion of the terminal part of the roof lining 6, so that the accuracy tolerance of the mutual alignment of the parts increases. As a result, the assembling workability is improved.

  Further, in the case of this locking structure, the first support surface 14 and the second support surface 15 that sandwich the curved portion of the terminal portion 7 are arranged in an outwardly opening tapered shape, so that depending on the insertion depth of the terminal portion 7 Since the locking force of the terminal portion 7 can be changed, there is an advantage that the operator can arbitrarily adjust the locking force when the roof lining 6 is assembled according to the situation such as an error of each portion.

  Furthermore, in this embodiment, since the outer surface shape of the upper bent wall 10 gradually changes from the first support surface 14 to the first base surface 12, the second support surface 15, and the orthogonal surface 16 in an obtuse angle, the pillar Occurrence of sink marks when the garnish 8 is resin-molded can be eliminated, and the surface aesthetics and the accuracy of the mating portion can be further improved.

Further, in the case of this locking structure, basically, the end portion 7 of the roof lining 6 is contacted and supported by the two surfaces of the first support surface 14 and the second support surface 15, so that only one surface is abutted. Therefore, the locking load acting on the upper bent wall 10 can be dispersed as compared with the case where the terminal portion 7 is locked. For this reason, since the latching area per surface can be made small, it becomes possible to eliminate the problem that an excessive load acts on one surface when the airbag is deployed. Therefore, when this locking structure is adopted, a difficult design considering damage on the pillar garnish 8 due to stress concentration is not forced, and stable deployment of the airbag 5 can be easily obtained. .
In the above embodiment, the end portion 7 of the roof lining 6 is contact-supported by only two surfaces of the first support surface 14 and the second support surface 15, but at least the first support surface 14 and As long as the second support surface 15 is in contact with the terminal portion 7, the terminal portion 7 may be contact-supported with more support surfaces.

Next, a second embodiment shown in FIGS. 4 and 5 will be described.
The basic configuration of this embodiment is substantially the same as that of the first embodiment, but a plurality of reinforcing ribs 20 (positioning locking portions) are integrally formed on the second support surface 15 in the first embodiment. The difference is that the position of the terminal portion 7 of the roof lining 6 in the longitudinal direction of the vehicle body is positioned by the reinforcing rib 20.

  The reinforcing ribs 20 are formed to protrude upward at a plurality of locations spaced apart in the vehicle front-rear direction of the second support surface 15, and have a basic function of connecting and reinforcing between the first base surface 12 and the orthogonal surface 16. However, a plurality of locking projections 21 corresponding to the reinforcing ribs 20 are formed at the set positions on the terminal portion 7 of the roof lining 6, and the locking projections 21 come into contact with the side surfaces of the reinforcing ribs 20. ing. Therefore, when the roof lining 6 is assembled, the terminal portion 7 can be easily and reliably positioned on the pillar garnish 8, and after the assembly, the terminal portion 7 is reliably prevented from shifting in the longitudinal direction of the vehicle body. be able to.

In this embodiment, the positioning locking portion is configured by the reinforcing rib 20, but positioning protrusions or depressions may be formed at arbitrary positions on the upper bent wall 10, and this may be used as the positioning locking portion. However, when the positioning locking portion is configured by the reinforcing rib 20 as in this embodiment, the number of parts can be reduced.
Further, in the above-described embodiment, the reinforcing rib 20 that functions as the positioning locking portion is formed on the second support surface 15. However, the reinforcing rib 20 is formed on the first support surface 14 instead of the second support surface 15. It is also possible. In addition, the reinforcing rib 20 can be formed on both the first support surface 14 and the second support surface 15.

Next, a third embodiment shown in FIG. 6 will be described.
In this embodiment, the basic configuration other than the pillar garnish 8 is substantially the same as that of the first embodiment, but the configuration of the upper bent wall 110 of the pillar garnish 8 is slightly different.
That is, the upper bent wall 110 is formed with a base surface 113 corresponding to the second base surface (13) of the first embodiment at a position outside the vehicle compartment, and an end of the base surface 113 on the vehicle interior side. A curved support surface 30 that connects the portion and the vertical wall 9 is formed in a concave shape on the lower side, and the curved portion of the terminal portion 7 of the roof lining 6 is supported by the curved support surface 30 at multiple points.
The curvature of the terminal portion 7 is set to be larger than the radius of curvature of the curved support surface 30. When the curved portion of the terminal portion 7 is inserted into the curved support surface 30 when the roof lining 6 is assembled, the terminal portion 7. Are supported at multiple points within the curved support surface 30.

  Further, the end of the curved support surface 30 closer to the vehicle interior is inclined obliquely upward so as to form an acute angle with the exposed surface on the vehicle interior side of the vertical wall 9, and the terminal portion 7 of the roof lining 6 is connected to the curved support surface 30. The roof lining 6 and the pillar garnish 8 are exposed on the vehicle interior side in a state of being inserted into the main body without any gaps or steps.

  In this roof lining locking structure, the end portion 7 of the roof lining 6 is basically bent as in the first embodiment, and the curved portion is inserted into the curved support surface 30 on the pillar garnish 8 side to support the multipoint. Therefore, the displacement between the roof lining 6 and the pillar garnish 8 can be easily and reliably absorbed by the insertion structure of the both, and the support load for the roof lining 6 can be dispersedly supported at multiple points. can do.

FIG. 7 shows a fourth embodiment of the present invention.
The roof lining locking structure of this embodiment is to support the end portion 7 of the roof lining 6 at multiple points by the curved support surface 30 as in the third embodiment, but the curved support surface 30 includes a plurality of curved support surfaces 30. It is slightly different in that it is formed on the upper surface of the reinforcing rib 40.

  That is, a first base surface 12 and a second base surface 13 are formed on the upper bent wall 10 of the pillar garnish 8 in the same manner as in the first embodiment. Orthogonal surfaces 16a and 16b are provided at the end portion and the end portion outside the passenger compartment, and a plurality of reinforcing ribs 40 are provided to connect the orthogonal surfaces 16a and 16b in the vehicle width direction. A curved support surface 30 is formed so as to be recessed downward. The terminal portion 7 of the roof lining 6 is curved in the same manner as in the third embodiment, and the curved portion is supported at multiple points by the curved support surface 30 of the reinforcing rib 40. The terminal portion 7 is formed with a locking projection 21 that can come into contact with the side surface of the reinforcing rib 40, and the terminal portion 7 of the roof lining 6 is brought into contact with the pillar garnish 8 by the contact of the locking projection 21 with the reinforcing rib 40. The vehicle is positioned in the longitudinal direction of the vehicle body.

  Therefore, the roof lining locking structure of this embodiment can obtain the same effect as that of the third embodiment, and can be easily positioned in the longitudinal direction of the vehicle body when the roof lining 6 is assembled, After assembly, there is a further effect that the displacement of the roof lining 6 can be reliably prevented.

Next, a fifth embodiment of the present invention shown in FIG. 8 will be described.
The roof lining locking structure of this embodiment is an improvement of the end portion of the roof lining 6 and can be applied to the structure of the pillar garnish of any of the first to fourth embodiments described above.

  In the roof lining 6 of this embodiment, the penetration width of the pillar garnish 8 toward the upper bent wall side is not constant, and the width W0 of the pillar garnish 8 near the center in the longitudinal direction of the vehicle body is the maximum. The widths W1 and W2 are gradually reduced in the front-rear direction. Therefore, the length of the curved portion of the terminal portion 7 is maximized in the vicinity of the central portion, and gradually decreases in the longitudinal direction of the vehicle body. As a result, the locking load acting on the terminal portion 7 is maximized in the vicinity of the central portion. As the vehicle goes in the longitudinal direction, it gradually becomes smaller.

  In the roof lining locking structure of this embodiment, since the sinking widths W0 to W2 of the terminal portion 7 are gradually decreased in the longitudinal direction of the vehicle body, an excessive locking force is prevented from being generated in the pillar garnish 8 portion. Thus, the airbag can be smoothly deployed, and can be easily adjusted so as to have an appropriate locking force by changing the gradient of change of the sinking widths W0 to W2. In addition, by adjusting the change gradient of the sinking widths W0 to W2 of the terminal portion 7, it is possible to easily adjust the jumping-in preventing force into the vehicle interior at the initial stage of airbag deployment. Therefore, since the influence of member strength and the like that differs for each vehicle type can be reliably absorbed by adjusting the gradient of change in the widths W0 to W2, the timing of deploying the airbag downward can be easily set and adjusted.

In addition, this invention is not limited to said embodiment, A various design change is possible in the range which does not deviate from the summary. For example, in FIGS. 3 and 5, the first and second support surfaces 14 and 15 for locking the terminal portion 7 of the roof lining 6 are formed in a part of the center of the pillar garnish 8 in the longitudinal direction of the vehicle body. The first and second support surfaces 14 and 15 may be formed so as to extend over the entire width of the pillar garnish 8. That is, the width of the first and second support surfaces 14 and 15 in the first and second embodiments and the width of the curved support surface 30 in the third and fourth embodiments depend on the locking strength of the roof lining 6 and the like. May be set as appropriate.
In the above description, the roof lining locking structure according to the present invention is applied to the joint portion between the roof side rail 2 and the center pillar 3 of the vehicle shown in FIG. The structure can be similarly applied to the connecting portion between the roof side rail 2 and the C pillar 40, the D pillar 41, and the like.
