Description

The present invention relates to a pillar garnish attaching device for attaching a pillar garnish to a pillar body member.
In the following, the pillar garnish is also referred to as “garnish”, the pillar body member as “body member”, the pillar garnish attachment device as “garnish attachment device”, and the curtain airbag as “CSA” (“CSA” is an abbreviation of “Curtain Sealed Airbag”).

FIG. 24 and FIG. 25, or Patent Document 1 show a garnish attachment device 1 that attaches the garnish 3 to the body member 8 with the clip 2. The garnish attachment device 1 is a comparative garnish attachment device (hereinafter, also referred to as “comparison device”) shown in comparison with the present invention. The garnish attachment device 1 includes the garnish attachment devices 1A and 1B shown in FIGS.
The clip 2 includes a clip 2B having a tether portion 2a and an anchor portion 2b (the clip shown in FIG. 25; hereinafter also referred to as “tether clip 2B”), the tether portion 2a and the anchor portion 2b, and the tether portion 2a and There is a clip 2A (a clip shown in FIG. 24; hereinafter, also referred to as “general clip 2A”) having substantially the same structure as the tether clip except that it does not have the anchor portion 2b.
The front pillar extends obliquely toward the front and downward of the vehicle, and the CSA 7 extends along the front pillar from the upper part of the front pillar to the middle part toward the front and downward.
In the front pillar portion where the CSA 7 extends to the side of the clip 2, the tether clip 2B is used for the clip 2, and the front pillar portion where the CSA 7 does not extend to the side of the clip 2 (front where the CSA 7 extends). A general clip 2 </ b> A is used at a position lower and forward in the direction along the front pillar than the pillar portion.

The attachment structure to the body member 8 by the clip 2 of the garnish 3 in the comparison apparatus 1 is as follows.
The garnish 3 has a box-shaped pedestal portion 4 formed on the back surface of the garnish. A rectangular hole 5 is formed in the bottom wall 4a of the pedestal portion 4, and a part of the clip 2 is inserted therethrough. The CSA facing side wall of the pedestal portion 4 is inclined toward the CSA 7 in view of die cutting at the time of molding and embossing of the garnish surface.

When the clip 2 is a tether clip 2B, as shown in FIG. 25, the clip 2 is bent in a direction perpendicular to the garnish longitudinal direction, and perpendicular to the garnish longitudinal direction formed at the tip of the tether portion 2a. An anchor portion 2b that bulges in the direction to be moved, a seat portion 2c, a holding portion 2d that holds the base portion bottom wall 4a between the seat portion 2c, an elastic lip portion 2e, and an elastic claw portion 2f. The tether portion 2a and the anchor portion 2b are inserted into the pedestal portion 4 through the rectangular hole 5 and accommodated. The clip 2 is inserted into the hole 6 of the body member 8, and the hole peripheral portion of the body member 8 is held between the elastic lip portion 2 e and the elastic claw portion 2 f to be fixed to the body member 8.
When the CSA 7 is deployed, the tether clip 2B does not come off from the body member 8, the garnish 3 moves in a direction away from the body member 8 with respect to the clip 2, and the anchor portion 2b of the clip 2 is the peripheral portion of the hole 5 in the pedestal bottom wall 4a. The movement of the garnish 3 stops at the position where the garnish 3 is caught, and scattering of the garnish 3 into the vehicle interior is prevented. In the case of the tether clip 2B, the engagement strength between the elastic claw 2f and the body member 8 is high. At the time of maintenance, the garnish 3 is forcibly detached from the body member 8 together with the clip 2.

When the clip 2 is a general clip 2A, as shown in FIG. 24, the clip 2A does not have a tether portion and an anchor portion but has a head portion (pressing portion) 2g. A groove 9 (corresponding to the hole 5 of the clip 2B) is formed in the pedestal bottom wall 4a so as to extend in the garnish longitudinal direction from the bottom wall center to the bottom wall end. The clip 2 is mounted in the groove 9 and has substantially the same configuration as the clip 2B except that the pedestal bottom wall 4a is held by the head 2g and the seat 2c.
The garnish 3 is detached from the body member 8 together with the clip 2A during both the CSA 7 deployment and maintenance. In the case of the general clip 2A, the engagement strength between the elastic claw portion 2f and the body member 8 is lower than that in the case of the tether clip.

It is necessary for the garnish 3 to suppress the rotation backlash around the garnish longitudinal axis (hereinafter, also simply referred to as “rotation backlash”) with respect to the body member 8 so as not to generate backlash while the vehicle is traveling.
The backlash of the garnish 3 is that of the elastic lip 2e of the clip 2 at the contact seating surface with the body member 8, and the backlash of the bottom wall 4a of the base 4 with respect to the clip seat 2c. Is the sum of

The rotation backlash at the contact seating surface of the elastic lip 2e with the body member 8 is suppressed by setting the width in the direction perpendicular to the garnish longitudinal direction of the contact seating surface of the lip 2e to a predetermined width W1p. . W1p is a value that is approximately 14 to 20 mm.
The backlash of the pedestal bottom wall 4a relative to the clip seat 2c is determined by setting the width of the contact surface between the pedestal bottom wall 4a and the clip seat 2c in the direction perpendicular to the garnish longitudinal direction to a predetermined width W2p. It is suppressed. W2p is a value that is approximately 14 to 20 mm.

The width direction dimension W3 in the viewed direction can be shortened as compared with the garnish width dimension W3p of the comparison device.
Similarly, if W1 is equal to or greater than W1p of the comparison device of FIGS. 24 and 25, the rotation play of the clip on the body member is equal to or less than the rotation play of the comparison device clip on the body member. A smaller amount of rotational rattling can be suppressed.

  According to the garnish attachment device of the above (2), the following width reduction effect of the structure in which the rib and the rib contact portion are combined can be obtained. That is, the vertical wall extends in a direction perpendicular to or inclined with respect to the seat portion, and the rib is held between the vertical wall and the head portion of the pin portion with the head, so the rib and the rib contact portion are combined. The dimension W4 in the width direction in the direction seen from the driver in the direction perpendicular to the garnish longitudinal direction of the structure is the direction seen from the driver in the direction perpendicular to the garnish longitudinal direction of the base of the comparison device. It can be made smaller than the dimension W4p in the width direction. Therefore, the space of the sum structure of the rib and the rib contact portion can be saved in the width direction in the direction seen from the driver in the direction orthogonal to the garnish longitudinal direction, and the curtain airbag is accordingly disposed on the rib and rib contact portion side. Can be sent to. As a result, the garnish can be narrowed and the visibility can be improved.

  According to the garnish attachment device of the above (3), the following width reduction effect of the structure in which the rib and the rib contact portion are combined can be obtained. That is, the end wall extends in a direction perpendicular to or inclined with respect to the seat portion, and the rib is held in the guide groove of the end wall. Compared to the section, the width can be shortened from W4p of the comparison device to W4 of the present invention in the width direction in the direction perpendicular to the garnish longitudinal direction and viewed from the driver. Therefore, the space of the sum structure of the rib and the rib contact portion can be saved in the width direction in the direction seen from the driver in the direction orthogonal to the garnish longitudinal direction, and the curtain airbag is accordingly disposed on the rib and rib contact portion side. Can be sent. As a result, the garnish can be narrowed and the visibility can be improved.

  In the garnish attachment device of (4), the device of (1) is applied to a tether clip. Also, by raising the tether part from the seat part in a direction perpendicular to the seat part, the garnish can be made narrower and the field of view can be reduced compared to the case where the inclined wall of the base part of the comparison device is inclined to the curtain airbag side. Improvements can be made.

  In the garnish attachment device of the above (5), scattering of the garnish into the vehicle interior can be prevented by engaging the anchor portion of the tether clip with the edge portion of the slit provided in the rib when the curtain airbag is deployed.

According to the garnish attachment device of the above (6), the following width reduction effect of the structure in which the rib and the rib contact portion are combined can be obtained. In other words, the vertical wall extends in a direction perpendicular to or inclined with respect to the seat portion, and the rib contacts the vertical wall. The dimension W4 in the width direction in the direction seen from the side can be made smaller than the dimension W4p in the width direction in the direction seen from the driver in the direction perpendicular to the garnish longitudinal direction of the base part of the comparison device. Therefore, the space of the sum of the rib and the rib contact portion can be saved in the width direction in the direction seen from the driver in the direction orthogonal to the garnish longitudinal direction, and the curtain airbag is brought closer to the rib and rib contact portion side. Can do. As a result, the garnish can be narrowed and the visibility can be improved.
Further, when the curtain airbag is deployed, the anchor portion engages with the edge of the slit of the rib, thereby preventing the garnish from being scattered into the vehicle interior.

[Example 1]
The garnish attaching apparatus 10 of Example 1 is demonstrated with reference to FIGS. 1-4.
The garnish attachment device 10 is a device for attaching the garnish 20 to the body member 11 using a clip 40.
The garnish 20 is, for example, an A pillar garnish.
The body member 11 is an A-pillar body member, for example, and includes an inner panel 11a, an outer panel 11b, and a reinforcement 11c. The garnish 20 is attached to the inner panel 11a.

In FIG. 1, 13 is a wire harness, a drain hose, etc. which are arranged in the vehicle front side space of the clip 40, 14 is a windshield, and 15 and 16 are weather strips. A substantially rectangular or substantially circular hole 17 is formed in the clip mounting portion of the body member 11, and the clip 40 is fixed to the body member 11 by inserting the head 44 of the clip 40 into the hole 17. Is done.
At the time of a vehicle collision, the garnish 20 is pushed away from the body member 11 by being pushed by the deploying CSA 12, and the CSA 12 is deployed and expanded rearward from the gap between the body member 11 and the garnish 20. In FIG. 1, 12 'shows the expanded CSA, and 20' shows the moved garnish.

  As shown in FIG. 1, the garnish attachment device 10 includes a rib 21 and a clip 40. The rib 21 and the clip 40 are made of resin. The rib 21 is formed integrally with the garnish 20.

  The rib 21 is formed on the back surface of the garnish 20 locally in the garnish longitudinal direction and along the garnish longitudinal direction. The rib 21 extends in the garnish longitudinal direction and extends toward the body member 11. The rib 21 does not have a box-type structure having a pedestal bottom wall and a pedestal side wall, like the pedestal 4 of the comparison device 1 of FIGS. The rib 21 is formed of a flat plate-like wall that is rectangular when viewed in a direction perpendicular to the garnish longitudinal direction. The rib 21 is substantially parallel to the central axis 47 of the clip head 44 (substantially perpendicular to the seat 42) or toward the rear of the vehicle as it approaches the garnish 20 from the clip 40 (ie, approaches the extension of the CSA 12 or CSA 12). Inclined to the side (inclined with respect to the seat 42). The rib 21 does not have a side wall extending in a direction orthogonal to the garnish longitudinal direction.

The clip 40 has a contact seat surface 41 with the body member 11, a seat portion 42 parallel to the contact seat surface 41 (parallel to the clip mounting portion of the body member 11), and a rib extending from the seat portion 42 to the garnish 20 side. 21 and a rib contact portion 43 that comes into contact with 21. The rib contact part 43 should just be what contacts the rib 21, for example, may be a wall, a small plane, and a protrusion.
The shape of the surface of the seat portion 42 orthogonal to the clip head central axis 47 is a rectangle.
The rib contact portion 43 is substantially orthogonal to the seat portion 42 or is inclined with respect to the seat portion 42. When the rib contact portion 43 is inclined toward the seat portion 42, the rib contact portion 43 is inclined toward the rear of the vehicle (that is, toward the CSA 12 or the extension of the CSA 12) as it approaches the garnish 20 from the clip 40.
A reinforcing rib 43a for reinforcing the rib contact portion 43 from the CSA side is formed integrally with the rib contact portion 43 and the seat portion.
The rib 21 and the rib contact portion 43 are parallel or substantially parallel to each other and contact each other.

The clip 40 further includes a head 44 inserted into the hole 17 of the body member 11, an elastic claw 45 formed on the head 44, and an elastic lip 46 formed on the elastic claw 45 side of the seat 42, Have An end portion of the elastic lip portion 46 extending in the garnish longitudinal direction is inclined toward the body member 11 and is elastic when pressed against the body member 11.
The contact seating surface 41 of the clip 40 with the body member 11 is constituted by a contact surface of the elastic lip 46 with the body member 11.

A slit is provided around the elastic claw portion 45 except for the connecting portion with the head portion 44, and the elastic claw portion 45 can be elastically displaced in a direction of moving back and forth in the head central axis 47.
When the head 44 is inserted into the hole 17 of the body member 11, the elastic claw 45 is retracted toward the head central axis 47, and the elastic claw 45 passes through the hole 17 in one direction. After the elastic claw portion 45 is inserted through the hole 17, the elastic claw portion 45 returns to the side away from the head central axis 47 by its own elasticity, and the elastic claw portion 45 and the head 44 pass the hole 17 in the one direction. The clip 40 is prevented from coming off the body member 11 through the opposite direction. In the state where the clip 40 is mounted on the body member 11, the peripheral edge portion of the hole 17 of the inner panel 11 a of the body member 11 is sandwiched between the elastic claw portion 45 and the elastic lip portion 46, and the clip 40 is attached to the body member 11. Fixed.

The clip detachment prevention force by the elastic claw portion 45 differs between a general clip and a tether clip.
When the clip 40 is a general clip, the clip detachment prevention force by the elastic claw portion 45 is set small. At the time of CSA deployment, the garnish 20 is pushed away from the body member 11 by the CSA 12, and the garnish 20 is detached from the body member 11 together with the clip 40 at the clip 40 site. Even during maintenance, the garnish 20 is detached from the body member 11 at the clip 40 site together with the clip 40.

The rib contact portion 43 is a portion of the seat portion 42 that is located farther from the CSA 12 or its extension than the end portion of the CSA 12 (for example, the side of the seat portion 42 that is farther from the CSA 12 or its extension than the head central axis 47). Extending from the portion located on the garnish 20 side. The rib contact portion 43 is inclined to the rear of the vehicle (to the side closer to the CSA 12 or its extension) as approaching the garnish 20 with respect to the seat portion 42 or a line perpendicular to the seat portion 42.
Further, the contact surface of the rib contact portion 43 with the rib 21 faces the same direction as or substantially the same as the direction in which the rib contact portion 43 extends, and is perpendicular to the seat portion 42 or a line perpendicular to the seat portion 42. On the other hand, as the garnish 20 is approached, the vehicle leans backward.

The contact seating surface 41 of the body member 11 of the clip 40 (the contact seating surface 41 of the elastic lip 46 with the body member 11) is in a direction along the contact seating surface 41 and in a direction perpendicular to the garnish longitudinal direction. It has a predetermined width W <b> 1 that can suppress the rotation rattling around the garnish longitudinal axis between the clip 40 and the body member 11.
The width W1 is preferably equal to or larger than the width W1p of the contact seating surface of the comparison device 1. The width W1 is approximately 14 mm to 20 mm. Here, “substantially” means that a variation of ± 10% is included.

  The width of the seat 42 of the clip 40 in the direction parallel to the contact seating surface 41 and perpendicular to the garnish longitudinal direction is substantially equal to the width W1 of the contact seating surface 41 in the same direction or as shown in FIG. Thus, it is desirable that it is W1 or less.

  Further, the engagement span (the contact surface or rib of the contact surface between the rib contact portion 43 and the rib 21) in the direction in which the contact surface or the rib contact portion 43 extends in the contact surface between the rib contact portion 43 and the rib 21. The distance between both ends in the direction in which the contact portion 43 extends is set to a predetermined span W2 that can suppress backlash in the direction perpendicular to the garnish longitudinal direction between the rib contact portion 43 and the rib 21. The predetermined span W2 is desirably equal to or greater than the engagement span W2p of the comparison device 1, and is approximately 14 mm or greater. Here, “substantially” means that a variation of ± 10% is included. The upper limit of W2 may be an arbitrarily large value as long as the rib contact portion 43 does not reach the garnish 20, and may be, for example, 50 mm or more.

The predetermined span W2 can be easily set larger than W2p of the comparison device 1 without adversely affecting the narrowing of the garnish 20.
The reason is that the direction of the contact surface between the rib contact portion 43 and the rib 21 is oriented in a direction substantially orthogonal to the seat portion 42 or in a direction inclined with respect to the seat portion 42. This is because even if it is larger than W2p of the apparatus 1, it does not directly lead to increasing the width of the garnish 20. Therefore, the predetermined span W2 can be set to a large value equal to or larger than W2p while maintaining the narrow width of the garnish 20.
The above configuration is applied to all embodiments of the present invention described later.

Example 1 further has the structure shown in FIGS.
The clip 40 of Example 1 is a general clip.
The rib contact portion 43 has a vertical wall 50 extending from the seat portion 42 toward the garnish 20 and a pin portion 51 with a head. The pin portion 51 with a head includes a head portion 51 a that is parallel to the vertical wall 50, and a shaft portion 51 b that is orthogonal to the vertical wall 50 and connects the head portion 51 a and the vertical wall 50. Between the head 51a and the vertical wall 50, the thickness of the rib 21 is substantially equal (however, a minute amount larger than the thickness of the rib 21), and the rib 21 can be slid with respect to the head 51a and the vertical wall 50. A gap is provided. The rib 21 is slidably inserted into the vertical wall 50 and the head 51a in the gap.

As shown in FIG. 3, the rib 21 is formed with a groove 30 extending in the garnish longitudinal direction from one side of the rib 21 in the width direction (the same direction as the garnish longitudinal direction) to the center in the width direction of the rib 21. The groove 30 is open toward the front of the vehicle.
In a state where the rib 21 is in contact with the rib contact portion 43, the rib 21 is held between the vertical wall 50 of the rib contact portion 43 and the head portion 51 a of the pin portion 51 with head, The shaft portion 51 b is fitted in the inner portion of the groove 30 of the rib 21. In this state, the head-attached pin portion 51 is located in the center portion in the width direction of the rib 21. The width of the groove 30 is smaller and larger than the outer diameter of the shaft portion 51b of the pin portion 51 with head, and is smaller than the outer diameter of the head portion 51a of the pin portion 51 with head.

The engagement span W <b> 2 between the rib contact portion 43 and the rib 21 is a distance between both ends of the contact surface between the rib contact portion 43 and the rib 21.
The rib contact portion 43 and the rib 21 are in contact with each other over the entire length of the engagement span W2. Since the rib 21 is restrained from moving in a direction away from the rib contact portion 43 by the head portion 51a of the pin portion 51 with a head portion, the contact between the rib contact portion 43 and the rib 21 is maintained.

Next, operations and effects of the first embodiment will be described.
First, in the garnish mounted state, the rotation rattling around the garnish longitudinal axis relative to the body member 11 of the garnish 20 is suppressed.
The rotation play of the garnish 20 with respect to the body member 11 is the sum of the rotation play with respect to the body member 11 of the contact seating surface 41 of the clip 40 and the rotation play with respect to the rib contact portion 43 of the rib 21.

  The contact seating surface 41 with the body member 11 of the clip 40 has a predetermined width W1 (for example, approximately equal to or more than W1p of the comparison device 1 in a direction along the contact seating surface 41 and perpendicular to the garnish longitudinal direction, For example, the rotation backlash of the clip 40 with respect to the body member 11 is suppressed to a backlash equivalent to or less than the backlash of the clip with respect to the body member of the comparison device 1. The

  Further, the engagement span of the contact surface between the rib contact portion 43 and the rib 21 in the direction in which the contact surface extends is set to a predetermined span W2 (for example, approximately equal to or greater than W2p of the comparison device 1, for example, approximately, 14 mm or more), the backlash of the garnish 20 with respect to the clip 40 is suppressed to a backlash similar to or less than that of the backlash with respect to the clip of the garnish in the comparison device 1.

  Further, since the rib contact portion 43 is orthogonal to the seat portion 42 or is inclined with respect to the seat portion 42, the width of the garnish 20 can be obtained even if the engagement span W2 is, for example, about W2p of the comparison device 1 or larger. The size of the garnish 20 is not increased, and rotation of the garnish 20 can be suppressed while the garnish 20 is narrowed.

  In addition, since the garnish 20 has one rib 21 instead of the box-shaped pedestal portion 4 in the comparison device 1, the pedestal width W4p of the comparison device 1 is equal to the rib 21 and the rib contact portion 43 in the present invention. Is reduced to a width W4 in a direction orthogonal to the garnish longitudinal direction and in a direction viewed from the driver. As a result, the CSA 12 or its extension can be brought closer to the rib contact portion 43 side, and the width W3 of the garnish 20 in the direction perpendicular to the garnish longitudinal direction and viewed from the driver is compared. It can be made thinner than the garnish width W3p of the apparatus. By reducing the width of the garnish 20, the field of view can be improved.

Further, the rib contact portion 43 is located on the side farther from the CSA 12 or its extension than the CSA 12 side end of the seat 42 (for example, located on the side farther from the CSA 12 or its extension than the head center axis 47). The rib contact portion 43 and the rib 21 are located farther from the CSA 12 or its extension than the CSA-facing oblique wall of the box-shaped pedestal portion 4 of the comparison device 1. Accordingly, in the present invention, the CSA 12 or its extension can be brought closer to the clip 40 side, and the garnish 20 can be further narrowed in the direction perpendicular to the garnish longitudinal direction.
The above operations and effects are applied to all the embodiments of the present invention.

Example 1 has the following operations and effects in addition to the operations and effects described above.
The clip 40 according to the first embodiment is used for attaching the garnish 20 to the body member 11 at a portion where the CSA 12 does not extend to the side of the clip. Accordingly, in FIG. 1, the extension of the CSA 12 is indicated by a two-dot chain line 12 ′, assuming that the extension of the CSA 12 is on the side of the clip 40. When the CSA 12 is deployed, the garnish 20 is detached from the body member 11 together with the clip 40. Even when the garnish 20 is removed from the body member 11 during maintenance, the garnish 20 is detached from the body member 11 together with the clip 40. The clip 40 is detached from the body member 11 by the elastic claw portion 45 being elastically displaced toward the head axis 47 when a pulling force is applied to the clip 40. The garnish 20 and the clip 40 are not separated from each other in the axial direction of the head 44.

  Further, since the vertical wall 50 is orthogonal to or inclined with respect to the seat portion 42 and the rib 21 is held between the vertical wall 50 and the head portion 51a of the pin portion 51 with head, the rib 21 The vertical wall 50 and the head 51a are overlapped, but the width in the direction perpendicular to the garnish longitudinal direction (rib 21 thickness direction) is the width of the pedestal of the comparison device 1 in the direction perpendicular to the garnish longitudinal direction. It can be made smaller. Then, the extension of the CSA 12 can be moved toward the rib 21 and the rib contact portion 43 by reducing the width. As a result, the width of the garnish 20 from W3p to W3 can be reduced, and thereby the visibility when viewed from the driver can be improved.

[Example 2]
5-12 shows the garnish attaching apparatus 10 of Example 2. FIG. Of the configuration, operation, and effect of the garnish attachment device of the first embodiment, the part that can be applied to all the embodiments is also applied to the second embodiment.

The garnish attachment device 10 according to the second embodiment further has the following configuration.
The clip 40 of Example 2 is a general clip. In FIG. 1, FIG. 1 is a diagram in which the general clip remains as it is, and the CSA 12 remains as a CSA extension (indicated by a two-dot chain line).
The rib contact portion 43 has an end wall 52 positioned at both ends of the rib contact portion 43 in the garnish longitudinal direction, and a central wall 53 positioned at the center portion of the rib contact portion 43 in the garnish longitudinal direction. The end wall 52 and the central wall 53 are substantially orthogonal to the seat portion 42 or inclined.
The end walls 52 extend from both ends of the seat portion 42 in the garnish longitudinal direction to the garnish 20 side. The end wall 52 has guide grooves 54 into which both ends of the rib 21 in the garnish longitudinal direction are slidably inserted. The central wall 53 has a claw portion 55 that extends from the central portion of the seat portion 42 in the longitudinal direction of the garnish toward the garnish 20 and protrudes toward the rib 21 on the rib facing surface.
The rib 21 has a hole 31 at a position facing the claw portion 55.

In a state where the rib 21 is engaged with the rib contact portion 43, both end portions in the garnish longitudinal direction of the rib 21 are inserted into the guide grooves 54 of the end wall 52, and the claw portion 55 of the central wall 53 is the hole 31 of the rib 21. Has entered.
As shown in FIG. 7, the engagement span W2 between the rib 21 and the rib contact portion 43 is equal to both ends of the contact portion between the garnish longitudinal direction ends of the rib 21 and the guide groove 54 (in the direction in which the rib contact portion 43 extends). Distance between both ends).

The second embodiment further has the following actions and effects.
The clip 40 of the second embodiment is used for attaching the garnish 20 to the body member 11 at a portion where the CSA 12 does not extend to the side of the clip. When the CSA 12 is deployed, the garnish 20 is detached from the body member 11 together with the clip 40. Even when the garnish 20 is removed from the body member 11 during maintenance, the garnish 20 is detached from the body member 11 together with the clip 40. The clip 40 is detached from the body member 11 when the elastic claw portion 45 is elastically displaced toward the head axis 47 side. The engagement between the garnish 20 and the clip 40, that is, the engagement between the claw portion 55 and the hole 31 of the rib 21 does not come off during CSA deployment or maintenance.

  Further, the end wall 52 and the central wall 53 are substantially orthogonal to or inclined with respect to the seat portion 42, and the rib 21 is inserted into the guide groove 54 of the end wall 52. The width W4 in the direction seen from the driver in the direction perpendicular to the garnish longitudinal direction can be made smaller than the width W4p in the direction perpendicular to the garnish longitudinal direction of the pedestal portion of the comparison device 1. . And since the width is reduced, the extension of the CSA 12 can be moved toward the rib 21 and the rib contact portion 43 side. As a result, it is possible to reduce the width of the garnish 20 from W3p to W3 and thereby improve the visibility when viewed from the driver.

Example 3
FIGS. 13-23 shows the garnish attaching apparatus 10 of Example 3. FIG. Of the configuration, operation, and effect of the garnish attachment device of the first embodiment, the portions applicable to all the embodiments are also applied to the third embodiment.

The garnish attachment device 10 of Example 3 further has the following configuration.
In the third embodiment, the clip 40 includes a tether clip having a tether portion 48 and an anchor portion 49. In the case of a tether clip, the CSA 12 extends to the side of the clip 40. In Example 3, the general clip in FIG. 1 is changed to a tether clip, and the CSA 12 is changed to a solid line.
When the CSA 12 is deployed, the clip 40 does not come off from the body member 11, the garnish 20 is pushed by the CSA 12 and moves away from the clip 40, and the anchor portion 49 hits the edge of a slit (described later) of the rib 21 and stops. The CSA 12 develops toward the passenger compartment through a gap formed between the garnish 20 and the body member 11.

The tether portion 48 extends from the end portion of the seat portion 42 on the CSA 12 side substantially perpendicular to the seat portion 42 and extends to the garnish 20 side, bends to the opposite side of the CSA 12 and further bends to the body member 11 side. The cross-sectional shape of the tether portion 48 orthogonal to the longitudinal direction of the tether portion 48 is a rectangle, and the long side of the rectangle is directed in the garnish longitudinal direction.
The anchor portion 49 is formed at the tip of the taser portion 48. The anchor portion 49 bulges in the garnish longitudinal direction from the tether portion 48.

The rib 21 is made of a single flat wall. The rib 21 has an anchor portion insertion opening 22 and a slit 23.
The anchor portion insertion opening 22 has a width larger than the garnish longitudinal dimension of the anchor portion 49. The slit 23 extends from the anchor portion insertion opening 22 toward the leading end side of the rib (the leading end side toward the seat portion 42), and stops before reaching the leading end of the rib (at a rib protrusion 32 described later). The width of the slit 23 is larger than the garnish longitudinal dimension of the tether portion 48 and smaller than the garnish longitudinal dimension of the anchor portion 49.
The tether portion 48 and the anchor portion 49 extend through the anchor portion insertion opening 22 from the CSA 12 side of the rib 21 to the opposite side of the rib 21 from the CSA 12.

The rib contact portion 43 of the clip 40 is formed so that the leading end portion of the rib 21 is formed between the vertical wall 56 extending from the seat portion 42 toward the garnish 20 and the seat portion 42 so as to protrude toward the garnish 20 side. It has a seat projection 57 that holds in a direction parallel to the seat 42, and a presser 58 that extends from the vertical wall 56 through the slit 23 of the rib 21 and extends away from the CSA 12. The rib 21 has a rib protrusion 32 that protrudes on the side opposite to the vertical wall 56 at the tip of the rib 21. The holding portion 58 holds the rib protrusion 32 between the seat portion 42.
A protruding portion 58 a that protrudes toward the seat portion 42 and holds the rib protrusion 32 is formed at the tip of the pressing portion 58. When the CSA is deployed, the pressing portion 58 can be elastically deformed in a direction away from the seat portion 42 by being pressed by the rib protrusion 32.

With the rib 21 engaged with the rib contact portion 43, the tip end portion of the rib 21 is held between the vertical wall 56 and the seat protrusion 57 in a direction parallel to the seat portion 42. Further, the rib protrusion 32 is held between the seat portion 42 and the pressing portion 58 in a direction substantially orthogonal to the seat portion 42.
The engagement span W2 between the rib 21 and the rib contact portion 43 is between the rib 21 of the vertical wall 56 between the tip of the vertical wall 56 far from the seat 42 and the tip of the rib 21 on the body member 11 side. The distance in the direction in which the contact surface extends.
The base portion on the seat portion 42 side of the tether portion 48 and the rib contact portion 43 are arranged so as to be accommodated in the space on the garnish 20 side of the seat portion 42 of the clip 40.

The third embodiment further has the following actions and effects.
When the CSA is deployed, the garnish 20 is pushed by the deployed CSA 12 to move away from the body member 11. At this time, the holding portion 58 is pushed by the rib projection 32 and elastically deforms, and the rib projection 32 and the holding portion are moved. The strength of the pressing portion 58 is determined in advance so that the engagement with 58 is released. When the garnish 20 moves away from the body member 11, the tether portion 48 slides into the slit 23, the anchor portion 49 engages with the edge of the slit 23 of the rib 21, and the garnish 20 stops moving. The garnish 20 is prevented from scattering toward the passenger compartment. The clip 40 remains engaged with the body member 11.

  In addition, since the base portion of the tether portion 48 on the seat portion 42 side extends from the CSA side end portion of the seat portion 42 at a substantially right angle to the seat portion 42, the inclined wall of the pedestal portion of the comparison device faces the curtain airbag side. Compared to the case of inclining, the CSA 12 can be brought closer to the tether portion 48 side, so that the garnish 20 can be made narrower and the visibility when viewed from the driver can be improved.

  Further, the base portion on the seat portion 42 side of the tether portion 48 and the rib contact portion 43 are arranged so as to fit in the space on the garnish 20 side of the seat portion 42 of the clip 40, and the rib 21 is a vertical wall. 56, the width W4 in the direction perpendicular to the garnish longitudinal direction and the direction viewed from the driver of the structure in which the rib contact portion 43 and the rib 21 are combined is set as the base of the comparison device 1. The width W4p in the direction perpendicular to the garnish longitudinal direction can be made smaller. Then, the CSA 12 can be brought closer to the rib contact portion 43 as much as the width W4 is reduced. As a result, it is possible to narrow the garnish 20 and improve the visibility when viewed from the driver.
