Description

  The present invention relates to a garnish having an insertion hole through which a webbing of a seat belt device is inserted.

  11A and 11B are diagrams showing a garnish having an insertion hole through which a conventional webbing is inserted, wherein FIG. 11A is an enlarged perspective view of a main part, FIG. 11B is a schematic view showing a webbing installation state, and FIG. It is explanatory drawing which shows the state which is carrying out self-excited vibration.

  As shown in FIGS. 11 (a) and 11 (b), the seatbelt device 100 includes a garnish 300 in which the webbing 110 pulled out from the retractor 200 installed in the side lining 310 forms a side wall surface in the vehicle interior. It is pulled out from the hole 330 into the vehicle interior, and is inserted into the through anchor 400 and the tongue (not shown) and fixed to the anchor (not shown). The insertion hole 330 is formed by a recess 321 formed in the pillar garnish 320 in the vehicle interior, and a side lining 310 provided so as to cover the recess 321 from the horizontal direction on the vehicle interior side.

  Conventionally, as a technique for preventing the webbing of the seat belt device from shaking in the front-rear and left-right directions, a rib projecting toward the pillar panel is provided below the webbing insertion hole on the garnish (center pillar lower member) side (Patent Document 1). A center pillar trim having a ball edge 32) is known (see, for example, Patent Document 1).

Further, when an automobile travels with the window open, the webbing of the seat belt device self-excites and flutters or generates wind noise due to the airflow (running wind) blown into the passenger compartment. As a means for preventing the webbing flapping and wind noise, a pillar structure of an automobile in which a rectifying member is provided on the upper side of the seat belt device on the inside of the pillar is known (for example, see Patent Document 2). ).

A rectangular cross section that is long in the front-rear direction so as to face the webbing arranged in a vertically extending state on the wall surface on the vehicle interior side of the garnish at the position Is formed into Jo, characterized in that it is formed in length and substantially the same length in the width direction of the webbing.

According to the garnish invention of claim 1, when the window is opened while the vehicle is running, airflow (running wind) enters the vehicle interior, and the vicinity of the webbing of the seat belt device is moved to the rear side of the vehicle interior. Flowing. When the airflow flows in the vicinity of the webbing, the flowing direction is changed by the build-up portion of the garnish, and the amount hitting the webbing is reduced. As a result, the deposition unit, and the webbing flutter by the airflow, and the fluttering sound is generated, the sound of flow of the air flow can be suppressed.

Further, according to the invention garnish according to claim 1, when the webbing is self-induced vibration by the airflow, the webbing is the padding portion protruding from the wall surface of the vehicle interior side of the garnish, it abuts against the garnish Is prevented from fluttering.

The invention of the garnish according to claim 2 is a garnish that covers the vehicle interior side of the vehicle body and has an insertion hole through which the webbing of the seat belt device is inserted in the middle part in the vertical direction. A through anchor through which the webbing is inserted is provided on the interior side of the garnish in the upper part of the insertion hole, and the webbing is provided on a wall surface on the interior side of the garnish between the insertion hole and the through anchor. A build-up portion that suppresses the self-excited vibration caused by the airflow, and the build-up portion faces the webbing on the wall surface of the garnish between the insertion hole and the through anchor and on the vehicle interior side. while being elongated in the vertical direction along the webbing by a wide longitudinal width at the upper end, into the insertion hole of the lower from the upper end Its width is formed so as to gradually decrease as I do, and wherein the distal end portion of the vehicle interior side is formed in a flat mountain shape.

According to the invention garnish according to claim 2, when the webbing is self-induced vibration by the airflow, the webbing is the padding portion protruding from the wall surface of the vehicle interior side of the garnish, it abuts against the garnish blocking Therefore, fluttering is suppressed.

  According to the garnish of the present invention, it is possible to prevent the webbing of the seat belt device from fluttering due to the airflow and the fluttering sound generated by the fluttering without impairing the appearance of the vehicle interior.

It is a guide hole. The insertion hole 2a is formed by a lower end portion of the recess 3a of the pillar garnish 3 and a protrusion 4a of the side lining 4 that is engaged with the inner wall of the recess 3a with a predetermined interval. In other words, the insertion hole 2a is formed as a long and narrow hole in the front-rear direction by inserting the flat plate-like convex portion 4a provided in the side lining 4 into the recess 3a formed in the pillar garnish 3.

The garnish 2 is not limited to one in which the pillar garnish (upper garnish) 3 and the side lining (lower garnish) 4 are formed separately. The garnish 2 only needs to have the standing wall 3b and the insertion hole 2a. For example, the pillar garnish 3 and the side lining 4 are integrally formed, and the insertion hole 2a is formed in the garnish 2 made of one member. It may be.
Hereinafter, the case where the pillar garnish 3 and the side lining 4 are separate garnishes 2 will be described as an example.

<Configuration of pillar garnish (upper garnish)>
As shown in FIG. 1, the pillar garnish 3 is an interior plate member that covers an upper portion of the pillar 11 of the vehicle body 1 on the vehicle interior side. A recess 3 a is formed at the lower end of the pillar garnish 3 so as to be inclined downwardly from the surface of the garnish 2 on the vehicle interior side.
The pillar garnish 3 constitutes the “garnish” recited in the claims and corresponds to the “upper garnish”.

As shown in FIG. 2, the recess 3 a is configured such that the intermediate portion of the webbing 51 wound around the retractor 52 and pulled out from the insertion hole 2 a toward the through anchor (also referred to as “shoulder belt anchor”) 54 is the side lining 4. It is a groove | channel for making it hide when seeing from the front-back direction by being pushed in by this convex part 4a in this recess 3a. The recess 3a is formed in a substantially U shape in plan view, and is formed of a recess that opens toward the interior of the vehicle interior. The recess 3a has a length S2 in the front-rear direction that is longer than the width S1 of the webbing 51. Standing wall portions 3b are formed at the front and rear ends of the recess 3a in the vehicle width direction.
The upright wall portion 3b prevents the webbing 51 from moving in the front-rear direction, guides the movement of the webbing 51 when the retractor 52 pulls in or pulls out by the occupant, and the airflow that the webbing 51 enters the vehicle interior. It is provided not to hit.

<Configuration of side lining (lower garnish)>
As shown in FIG. 1, the side lining 4 is an interior plate member that covers a lower portion of the pillar 11 of the vehicle body 1 on the vehicle interior side and a lower portion of the window frame portion 12 (see FIG. 2). On the upper end portion of the side lining 4, the convex portion 4a is integrally formed and bent at a substantially right angle toward the outside of the passenger compartment.
The side lining 4 constitutes the “garnish” recited in the claims and corresponds to the “lower garnish”.

  The projecting portion 4a is projected from the garnish 2 (side lining 4) toward the vehicle body 1 side (outside of the passenger compartment) so as to engage with the standing wall portion 3b before and after the recess 3a in the insertion hole 2a. Yes. The convex portion 4 a is disposed so that the tip thereof is always in contact with the surface of the webbing 51, and the webbing 51 is pushed into the recess 3 a of the pillar garnish 3.

≪Configuration of seat belt device≫
As shown in FIG. 1, the seat belt device 5 restrains the upper body of an occupant seated on the seat 6 with a webbing 51, for example, so-called three points with three anchor points to be fixed by the webbing 51. It consists of a type seat belt.
The seat belt device 5 includes a webbing 51 for restraining an occupant, a retractor 52 installed in the side lining 4 for winding up one end of the webbing 51, and an anchor 53 for fixing the other end of the webbing 51 to the vehicle body 1. A through anchor 54 which is provided on the top of the pillar 11 and through which the webbing 51 is inserted; a tongue 55 which is disposed between the through anchor 54 and the anchor 53 and through which the webbing 51 is inserted; And a buckle 56 fixed to the seat 6 or the like.

  The seat belt device 5 will be described as an example that does not have a seat belt adjuster function, but the present invention has the same effect even if it has a seat belt adjuster function. .

≪Effect of garnish≫
Next, the operation of the garnish 2 will be described with reference to FIGS.
For example, if the window is opened while the vehicle is running, the air current enters the vehicle interior from the direction of arrow A and flows in the vehicle interior side of webbing 51 in the rear direction of arrow B as shown in FIG. At this time, the webbing 51 arranged by being pulled out from the insertion hole 2a into the vehicle interior is disposed in the recess 3a of the pillar garnish 3, and the standing wall portion 3b is disposed on the front and rear sides thereof. To the convex portion 4a.

For this reason, the webbing 51 is prevented from being hit by the airflow that has entered the vehicle compartment from the direction of arrow A due to the arrangement of the webbing 51 in the recess 3a and the standing wall 3b.
Furthermore, the webbing 51 is always pressed toward the outside of the vehicle interior in the recess 3a by the convex portion 4a disposed on the vehicle interior side of the webbing 51, so that the webbing 51 is in a recessed position near the back wall of the recess 3a. Therefore, the influence of the airflow is suppressed. Further, the airflow flowing beside the webbing 51 is blocked by the standing wall portion 3b, so that even if it hits the webbing 51, it does not become an entrainment wind but flows in the rearward direction as a conditioned air.

As a result, even if the window is opened during traveling, it is possible to prevent the webbing 51 from fluttering due to the airflow and the occurrence of the fluttering sound.
Moreover, since the convex part 4a is arranged in the state of entering the recess 3a, the insertion hole 2a can be made smaller by the amount the convex part 4a enters the recess 3a, and therefore flows from the insertion hole 2a into the vehicle interior. By reducing the airflow, the sound of the airflow can be reduced.
Furthermore, since the insertion hole 2a can be made small, it is possible to prevent small articles from entering the insertion hole 2a.

  4A and 4B are diagrams showing the state of the webbing that vibrates due to the airflow. FIG. 4A is an explanatory diagram showing a comparative example showing the vibration state of the webbing when there is no convex part, and FIG. 4B is pressed by the convex part. It is explanatory drawing which shows the vibration state of the webbing which is.

  For example, the webbing 7 in the comparative example shown in FIG. 4A is in a state in which the space between the retractor 52 and the through anchor 54 is stretched between the retractor 52 and the through anchor 54 in a straight line. For this reason, when an air flow enters the vehicle interior from the window and travels in the backward direction during traveling, the webbing 51 is moved between the retractor 52 and the through anchor 54 toward the inside and outside of the vehicle interior by the air flow. Self-excited oscillation with the length L1 as a wavelength.

  In the case of the comparative example as shown in FIG. 4A, the webbing 7 has a long wavelength (L1), so that the webbing 7 is largely self-excited by the flow of airflow (running wind) entering the vehicle interior. For this reason, the webbing 7 hits the pillar garnish 3 (FIGS. 1 to 3) to generate a fluttering sound when self-excited.

In contrast, the webbing 51 in the present invention shown in FIG. 4B is pressed between the retractor 52 and the through anchor 54 by the convex portion 4a. For this reason, the space between the retractor 52 and the through anchor 54 is in a state of being bent in a dogleg shape.
Then, even when the webbing 51 is self-excited when the airflow enters the vehicle interior from the window and travels backward during traveling, the length L2 between the through anchor 54 and the convex portion 4a is used as the wavelength. Self-excited vibration.

  For this reason, the webbing 51 of the present invention shown in FIG. 4B has a length L2 that is substantially half the wavelength as compared with the wavelength (L1) of the webbing 7 of the comparative example shown in FIG. It is more than half the length. As a result, even if the webbing 51 vibrates, since the wavelength (L2) is short, the amplitude L3 that moves in the vehicle interior / exit direction is also shortened and does not contact the pillar garnish 3. In addition, even if the webbing 51 comes into contact with the pillar garnish 3, the force of hitting the pillar garnish 3 is weakened with the length of the wavelength (L2).

  As described above, the convex portion 4a that abuts the webbing 51 is disposed between the retractor 52 and the through anchor 54, thereby reducing the wavelength and amplitude of the webbing 51 by half, and the airflow entering the vehicle interior. It can be suppressed that the webbing 51 hits the pillar garnish 3 due to (running wind) and generates a fluttering sound.

  The present invention is not limited to the above-described embodiment, and various modifications and changes can be made within the scope of the technical idea. The present invention extends to these modifications and changes. Of course.

≪Modification≫
Next, each modification of the present invention will be described with reference to FIGS.
In addition, in each modification, the same code | symbol is attached | subjected to the member which has the same function as the garnish 2 which concerns on the said embodiment shown in FIGS. 1-4, and the overlapping description is abbreviate | omitted.

<First Modification>
Next, a first modification of the present invention will be described with reference to FIG.
FIG. 5 is an enlarged cross-sectional view of a convex portion showing a first modification of the garnish according to the embodiment of the present invention.
The convex part 4a (refer FIGS. 1-4) provided in the side lining 4 of the said embodiment forms the front-end | tip part with roundness 4b like the 1st modification shown in FIG. The vehicle interior side edge 3c may extend outside the vehicle compartment.

  As described above, by attaching the substantially semicircular round 4b to the front end of the convex portion 4a when viewed from the front-rear direction, the frictional resistance between the convex portion 4a and the webbing 51 is reduced. As a result, even if the convex portion 4 a is in contact with the webbing 51, the driver can pull out the webbing 51 smoothly with the tongue 55.

  Further, as shown in FIG. 5, a reinforcing rib 4c having a triangular shape or the like in a side view may be provided on the lower surface of the convex portion 4a. If it does in this way, the intensity | strength of the convex part 4a can be improved.

<Second Modification>
Next, a second modification of the present invention will be described with reference to FIGS. 6 (a), 6 (b), and 6 (c).
FIG. 6 is a view showing a second modified example of the garnish according to the embodiment of the present invention, in which (a) is a perspective view of an essential part, (b) is a longitudinal sectional view of an essential part of the garnish, and (c) is a recess. It is an enlarged plan view of the convex part engaged.

  The pillar garnish 3 (see FIGS. 1 to 4) of the embodiment is further provided with a depth of the lower end portion of the recess 3a as in the second modification shown in FIGS. 6 (a), 6 (b), and 6 (c). D1 is formed deeply, the height H1 of the standing wall portion 3b is formed high, and the protrusion length D2 of the convex portion 4a is inserted so that the tip of the convex portion 4a enters the vicinity of the back wall of the concave portion 3a accordingly. May be lengthened.

Thus, the depth H1 from the through anchor 54 in the webbing 51 to the upper end portion 3d of the standing wall 3b in the webbing 51 is formed by increasing the depth D1 of the recess 3a and increasing the height H1 of the standing wall 3b. Becomes shorter. Thereby, the distance D3 between the webbing 51 in the vicinity of the through anchor 54 and the pillar garnish 3 can be shortened.
For this reason, in the webbing 51, between the insertion hole 2a and the through anchor 54, the vertical wall portion 3b in which approximately half or more of the length of the portion positioned above the insertion hole 2a forms the inner walls before and after the recess 3a. Will be placed between.

Then, in the webbing 51 from the insertion hole 2a to the through anchor 54 (H3), the length from the insertion hole 2a to the upper end portion 3d of the standing wall 3b as seen from the front-rear direction as shown in FIG. 6B. Since the portion H1 is disposed in the recess 3a and the length H2 of the portion extending from the recess 3a from the upper end 3d of the standing wall 3b to the through anchor 54 is short, the standing wall 3b causes the window to enter the vehicle interior. Fewer parts will hit the incoming airflow.
Further, since the distance D3 from the webbing 51 to the pillar garnish 3 is also short, the webbing 51 is prevented from being vibrated by the standing wall portion 3b and free-running or fluttering.

<Third Modification>
Next, a third modification of the present invention will be described with reference to FIGS. 7 (a), (b), and (c).
The third modification (FIG. 7) to the sixth modification (FIG. 10) of the present invention to be described later reduce the airflow from hitting the webbing 31 by the built-up portions 3e, 3f, 3h, 3i, and the webbing 51 It reduces fluttering.
FIG. 7 is a view showing a third modified example of the garnish according to the embodiment of the present invention, in which (a) is a perspective view of the main part, (b) is a longitudinal sectional view of the main part of the garnish, and (c) is (a) ) Is a cross-sectional view in the direction of the arrows W-W in FIG.

  The pillar garnish 3 (see FIGS. 1 to 4) of the above embodiment is inserted into the pillar garnish 3 through the standing wall 3b as in the third modification shown in FIGS. 7 (a), 7 (b), and 7 (c). You may form by the built-up part 3e arrange | positioned upwards from the front side of the hole 2a.

In this case, as shown in FIG. 7A, the built-up portion 3 e is arranged with the lower end portion disposed on the upper end of the side lining 4 and directed upward along the webbing 51.
As shown in FIG. 7B, the build-up portion 3e is formed so that the thickness of the central portion is the largest, and the thickness gradually decreases from the central portion in the vertical direction. For this reason, the upper end part and lower end part of the built-up part 3e are installed in the state which does not have a level | step difference with respect to the pillar garnish 3 by front view.

  Moreover, as shown in FIG.7 (c), the buildup part 3e is formed with the standing wall part 3b in the rear-end side in which the webbing 51 is arrange | positioned. The build-up portion 3e has the maximum thickness of the standing wall portion 3b in plan view, and gradually decreases in thickness from the standing wall portion 3b along the surface of the pillar garnish 3 toward the front side. .

Thus, even if the standing wall 3b is formed only on the front side of the webbing 51, as shown in FIG. 7C, the flow C of the air flow when there is no built-up portion 3e is indicated by a solid arrow E. Instead of the flow, the airflow can be guided so as not to hit the webbing 51.
For this reason, the webbing 51 is restrained from self-vibrating or fluttering because the airflow hit by the direction of the flow of the airflow is changed by the build-up portion 3e.

<Fourth Modification>
Next, a fourth modification of the present invention will be described with reference to FIGS. 8 (a), (b), and (c).
FIG. 8 is a view showing a fourth modification of the garnish according to the embodiment of the present invention, in which (a) is a perspective view of the main part, (b) is a longitudinal sectional view of the main part of the garnish, and (c) is (a) ) Is a cross-sectional view in the direction of the arrow XX of FIG.

In this case, the built-up portion 3f and the standing wall portion 3g are formed symmetrically with respect to the webbing 51 with the built-up portion 3e of the third modified example.

Thus, even if the build-up portion 3f and the standing wall portion 3g are formed only on the rear side of the webbing 51, as shown in FIG. 8C, the air flow F when there is no build-up portion 3f Instead of the flow indicated by the arrow G, the airflow can be reduced from hitting the webbing 51.
For this reason, the webbing 51 hits because the flow of the airflow is guided and changed by the build-up portion 3f and the standing wall portion 3g, so that the vortex of the airflow that wraps around the pillar garnish 3 side of the webbing 51 does not occur. Since the vortex of the airflow is reduced, self-excited vibration and fluttering are suppressed.

<Fifth Modification>
Next, a fifth modification of the present invention will be described with reference to FIGS. 9 (a) and 9 (b).
