Description

  The present invention relates to a retractor cover mounting structure for covering a seat belt retractor.

  An automobile seat belt retractor is a seat belt retractor equipped with an emergency locking mechanism, and is fixed to a mounting hole provided in a pillar panel or other panel constituting an automobile interior, and a seat belt belt portion (webbing) It is covered with a lid-shaped resin retractor cover having an outlet opening (see, for example, Patent Document 1).

  By the way, there are cases where there are both specification settings for the presence or absence of a retractor seat belt in the same vehicle body shape. In such a case, the retractor cover is set as described above in the specification with the retractor, while the dummy cover for closing the retractor mounting hole is set in the specification without the retractor (for example, the rear seat of the 2-theta vehicle), or It must be closed with a metal panel similar to the pillar panel so as not to impair the quietness and appearance of the room.

JP 2000-16246 A

  However, in the actual production process, the specifications with retractor and those without retractor are mixed and flow on the same production line, so the operator determines the presence or absence of the retractor each time and selects either the retractor cover or the dummy cover. It was necessary to install the cover, and it was very troublesome and it was necessary to prepare two types of covers. Furthermore, in the case of a specification with a retractor, it is necessary to attach the retractor cover after inserting the webbing into the outlet, and this is also a factor that impairs workability. Of course, it is possible to separately close with a metal panel, but in that case, there is a problem that a new spot welding or screwing process is required, resulting in an increase in cost.

  Moreover, in the cover structure of the said patent document 1, since the attachment part to the vehicle body of a cover becomes a back surface of a webbing, it is necessary for an operator to work while pulling out a webbing with one hand so that an attachment part can be seen when attaching a cover. Therefore, the mounting work must be performed with one hand, and the workability has deteriorated.

  The present invention has been made in view of such a situation, and the object thereof is to enable the common use of a cover in each specification with and without a retractor in a vehicle body of the same structure, It is an object of the present invention to provide a retractor cover mounting structure that does not impair the function and that can be easily mounted and can reduce production costs.

  In order to solve the above-described problems of the prior art, the present invention provides a structure for attaching a retractor cover to a vehicle body that covers a retractor of a seat belt attached to the vehicle body from the indoor side. And an edge that rises toward the mounting surface on the outer periphery of the cover, and either the upper or lower edge in the mounting state of the cover A webbing outlet was provided in the section.

  Moreover, in this invention, the said fixing | fixed part was arrange | positioned symmetrically with respect to the axis | shaft of the up-down direction which passes a webbing exit. Furthermore, in the present invention, the webbing outlet has a notch shape opened to the outer periphery of the cover that is in contact with the vehicle body.

  In the present invention, the panel surface of the vehicle body fixing portion for fixing the cover is provided with a stepped portion that is lower than the basic design surface on the outdoor side, and the webbing relief portion that extends upward from the stepped portion to the basic design surface. Was provided.

  As described above, the retractor cover mounting structure according to the present invention is a retractor cover mounting structure for covering a retractor of a seat belt attached to a vehicle body from the indoor side. Arranged 180 degrees rotationally symmetrically about an axis perpendicular to the mounting surface, and formed with an edge that rises toward the mounting surface on the outer periphery of the cover, and either the upper or lower edge in the mounting state of the cover Since a webbing outlet is provided on the front panel, it is possible to handle each specification with or without a retractor with the same structure by simply changing the direction of mounting the cover. Can be expected to improve work efficiency. In addition, it is possible to share the cover parts in each specification, and it is possible to reduce the inventory of parts and to manage the inventory easily compared to the case where separate covers are prepared, and the production cost can be expected to be reduced. Furthermore, when the retractor is not specified, when the webbing outlet is attached to the vehicle body with the webbing outlet facing downward, the outlet becomes difficult to see and the interior appearance is not impaired.

  In addition, the configuration in which the fixing portion is arranged symmetrically with respect to the vertical axis passing through the webbing outlet enables the common use of cover parts on both the left and right sides of the vehicle, thereby further reducing the types of parts.

  And since the webbing outlet has a notch shape that opens to the outer periphery of the cover that comes into contact with the vehicle body, it is not necessary to insert the webbing into the outlet in advance even in the case of a specification with a retractor. A cover can be attached, and a significant improvement in workability can also be expected in this respect.

  In addition, a stepped portion that is lower than the basic design surface is provided on the panel surface of the vehicle body attachment portion that fixes the cover, and a webbing relief portion that extends upward from the stepped portion to the basic design surface is provided. When installed on the vehicle body with the webbing exit facing down, the exit is almost invisible due to the stepped portion, and the influence on the interior appearance and quietness can be minimized, and the escape portion is sufficient for the webbing exit. The height is ensured, the sliding resistance when the seat belt is pulled out and taken up is reduced, and the seat belt performance is improved. In addition, even when a gap is generated between the cover and the vehicle body due to deformation during molding of the cover or the panel in the mounted state, the gap becomes difficult to see due to the stepped portion, and an improvement in appearance can be expected.

Hereinafter, the present invention will be described in detail based on illustrated embodiments.
FIG. 1 is a perspective view showing a seat belt mounting portion that employs a retractor cover mounting structure according to an embodiment of the present invention.

  In the figure, the seat belt device 1 is configured such that a webbing 12 pulled out from a retractor 11 is folded back by a shoulder anchor 13 and a tip end portion is fixed to a vehicle body floor by an anchor 14 and a tongue 15 inserted through the webbing 12 is connected to a buckle (not shown). Therefore, the occupant is constrained at three points. The shoulder anchor 13 is screwed to an attachment location 20 provided on the top of the pillar panel 2 so as to be rotatable using a fastening member such as a bolt.

  The retractor 11 is fixed in a state of being accommodated in the mounting hole 21 at the lower part of the pillar panel 2. The retractor 11 is provided with a lower mounting portion 11a, an upper mounting portion 11c provided on the upper stay 11b, and two positioning holes 11d and 11d, respectively. The positioning holes 11d and 11d are placed in the mounting holes 21 below the pillar panel 2. The lower mounting portion 11a is screwed to the lower mounting portion 21a with a fastening member such as a bolt while being engaged with the protruding positioning claws 21d and 21d, and the upper mounting portion 11c is further screwed to the upper mounting portion 21c. It is fixed by screwing using the fastening member. The upper stay 11b may be omitted depending on the specification.

  The retractor cover 3 is provided so as to cover the retractor 11 fixed as described above from the indoor side. As shown in FIG. 3, the retractor cover 3 is formed in a slightly vertically long rectangular plane shape as a whole, and an edge portion 31 rising to the mounting surface side is formed on the outer peripheral portion thereof, so that the back of the cover is formed. A substantially lid shape having a recess 32 is formed. A webbing outlet 33 having a notch shape opened to the outer periphery of the cover is provided at the upper edge 31 in the drawing, which is the drawing side of the webbing.

  As means for attaching the retractor cover 3 to the vehicle body, fixing members 34 are provided at the four corners on the back of the retractor cover 3. As the fixing member 34, for example, as shown in FIG. 8, a resin clip (34) that can be inserted into a hole 35 drilled in the position of the retractor cover 3 can be used. Further, when the retractor cover 3 main body is formed of a resin molded product, the fixing member 34 ′ can be molded integrally with the retractor cover 3 ′ main body as shown in FIG. 9.

  The retractor cover 3 configured as described above has a basic design shape that is vertically and horizontally symmetrical with respect to the vertical center line y and the horizontal center line x orthogonal thereto, and the four fixing members 34 are attached to the vehicle body. Arranged 180 degrees rotationally symmetrically about an axis c (passing the intersection of x and y) perpendicular to the mounting surface (end surface of the edge 31).

  The mounting portion of the vehicle body (pillar panel 2) for fixing the retractor cover 3 is provided with a step 22a that is lower than the basic design surface 2a on the outdoor side, and a retractor mounting hole 21 is opened in the step portion 22 around the step 22a. Four fixing portions 24 corresponding to the fixing members 34 of the retractor cover 3 are provided. The fixing portion 24 is configured by a hole or the like in which a fixing member 34 made of, for example, a resin clip can be fitted and locked, and is arranged in a symmetrical positional relationship like the four fixing members 34.

  The pillar panel 2 above the attachment portion (22) of the retractor cover 3 is provided with a relief portion 23 for the webbing 12 that forms a slope that extends upward from the step portion 22 to the basic design surface 2a. The upper mounting portion 21c described above is provided further below the step portion 22 corresponding to the upper stay 11b located on the outdoor side of the webbing 12.

  In the retractor cover 3 configured as described above, in the specifications with the retractor, after the retractor 11 is attached, the fixing members 34 are fixed with the webbing outlet 33 facing upward as shown in FIGS. By fitting and fixing to the portion 24, the retractor 11 and its mounting hole 21 are covered, and the webbing 12 can be freely inserted and removed through the webbing outlet 33 and the relief portion 23. At this time, since the webbing outlet 33 has a notch shape opened to the outer periphery of the cover in contact with the vehicle body, the retractor cover 3 can be easily moved without passing the webbing 12 through the outlet even after the retractor 11 is attached. Can be attached to the car body.

  On the other hand, in the case of a non-retractor specification such as a rear seat of a 2-theta vehicle, the retractor cover 3 is rotated 180 degrees and attached upside down as shown in FIGS. In this state, since the webbing outlet 33 faces downward, the indoor appearance and quietness are not impaired. In particular, by providing the relief portion 23, the height of the webbing outlet 33 can be reduced while the step portion 22 is provided, and the influence on quietness can be minimized.

  Moreover, since it is only necessary to change the mounting direction of the same retractor cover 3, even if the specifications with the retractor and the specifications without the retractor are mixed on the same production line, the operator can easily cope. Furthermore, in this embodiment, since the retractor cover 3 and its fixing part 24 and fixing means 34 are both vertically symmetrical and horizontally symmetrical, the retractor cover 3 can be shared on the right and left sides of the vehicle body, and The person can perform the installation work in exactly the same way.

  In the above embodiment, the case where the retractor cover 3 is configured by the fixing member 34 made of a resin clip and the fixing portion 24 made of a hole that can be fitted and locked as the mounting means of the retractor cover 3 has been shown. However, the present invention is not limited to this, and may be a metal clip or the like, a screw or a screw such as a bolt, or a claw provided integrally with the retractor cover 3. Further, a locking member such as a fixing member 34 may be provided instead of the vehicle-side fixing portion 24 (hole), and a locked hole may be formed instead of the fixing member 34 on the retractor cover 3 side.

  Moreover, in the said embodiment, although the fixing member 34 and the fixing | fixed part 24 which comprise the fixing | fixed part of the retractor cover 3 are each arrange | positioned 4 each, if the positional relationship symmetrical in the up-down and left-right directions is maintained, several Can be set freely, and may be 2, 6, 8, etc. Further, in the illustrated example, the four practical fixing members 34 on the retractor cover 3 side are shown in the most practical case in which the fixing members 34 are arranged so as to form the vertices of the rectangle according to the shape of the cover. Arranging so as to form each vertex of the quadrilateral is also possible within the scope of the present invention. The planar shape of the retractor cover 3 is preferably symmetrical in the vertical and horizontal directions. However, the retractor cover 3 does not have to be completely symmetrical in the vertical and horizontal directions as long as it does not interfere with rotation by 180 degrees. Further, it is also possible to attach the retractor cover 3 on the right side of the vehicle to the left side and the retractor cover 3 on the left side of the vehicle to the right side by rotating 180 degrees, even if they are not symmetrical.

  Further, in the above embodiment, the case where the relief portion 23 is provided above the step portion 22 has been shown. However, when the step portion 22 is omitted or the height of the webbing outlet 33 is used, a gap necessary for entering and exiting the webbing 12 is provided. In the case of securing, etc., the escape portion 23 can be omitted. Moreover, in the said embodiment, although the case where the webbing outlet 33 made the notch shape which opened completely with respect to the outer peripheral part was shown, when the webbing outlet 33 is made into the slit shape which is not opening with respect to an outer peripheral part In addition, it is possible to share the cover parts by the configuration of the fixed portions (24, 34) symmetrical in the vertical and horizontal directions.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made based on the technical idea of the present invention.
