JP 2006-160016 A

  In the conventional retractor mounting device, all the load that pulls the retractor upward during belt anchor evaluation or vehicle collision is borne by the retractor bracket itself and the welding point of the retractor bracket. There have been problems such as an increase in the number of welding points, and an increase in the thickness of the retractor bracket in order to suppress deformation.

  An object of the present invention is to provide a retractor mounting device that can partly share the load that the retractor bracket receives from the retractor during belt anchor evaluation or vehicle collision with a body panel other than the retractor bracket.

The present invention for solving the above problems is as follows.
(1) retractor mounting apparatus of the present invention is connected to the upper body panel having a notch with an upper edge extending side edges and longitudinal direction extending vertically to the lower rear end portion, a lower end portion of the upper body panel Lower seat panel, rear pillar connected to the rear end of the upper body panel, and rear seat belt disposed in a space surrounded by the upper and side edges and rear pillar of the notch. And a retractor bracket connected to at least one member of the upper body panel, the lower body panel, and the rear pillar.

The inner panel includes an upper body panel and a lower body panel, the side portion of the vehicle body includes an outer panel and an inner panel, and a part of the upper body panel is cut away to provide the space where the retractor is disposed. A retractor is attached to the inner panel via a retractor bracket at a position where it is overlapped with the upper edge of the notch provided in the upper body panel in the vehicle width direction .
The retractor and the upper edge of the upper body panel cutout are spaced apart from each other, and a gap is provided between the retractor and the upper edge of the upper body panel cutout.

The clearance dimension D between the retractor and the upper edge of the upper body panel notch is not less than the dimension D1 necessary to absorb manufacturing errors, and is based on the amount D2 of upward movement of the retractor during belt anchor evaluation or vehicle collision. It is set to small.
The above ( 1 ) applies to all embodiments of the present invention.

In the retractor mounting device of ( 1) above, the upper body panel is, for example, a roof side inner panel, the lower body panel is, for example, a wheel house panel, and the rear pillar is, for example, a D pillar.
Also, the connection between the lower end of the upper body panel and the lower body panel, the connection between the rear end of the upper body panel and the rear pillar, and at least one member of the upper body panel, the lower body panel and the rear pillar and the retractor bracket The connection is, for example, connection by spot welding. The connection between the retractor and the retractor bracket is, for example, a connection using a bolt.
In ( 1 ) above, the amount of upward movement of the retractor at the time of belt anchor evaluation or vehicle collision is, for example, about 10 mm.
In the above ( 1 ), the dimension D1 is about 5 mm, for example, and the movement amount D2 is about 10 mm, for example.

( 2 ) In the retractor mounting device of ( 1 ) above, when the retractor moves upward at the time of belt anchor evaluation or at the time of vehicle collision, the upper body panel notch A recess for receiving the edge is formed.
The above ( 2 ) is applied to the second embodiment of the present invention.

( 3 ) In the retractor mounting device according to ( 1 ) or ( 2 ) above, the reinforcement is arranged at a position that is separated from the upper end of the retractor by a dimension that is greater than or equal to D1 and smaller than D2. The reinforcement is attached to either the upper body panel, the rear pillar, both the upper body panel and the rear pillar.
The above ( 3 ) is applied to the third embodiment of the present invention.

According to the retractor mounting device of (1 ) above, the clearance dimension between the retractor and the upper edge of the upper body panel notch is set to be smaller than the amount of upward movement of the retractor at the time of belt anchor evaluation or vehicle collision. Therefore, when the retractor is pulled by the seat belt and moves upward during the belt anchor evaluation or the vehicle collision, the retractor contacts the upper edge of the upper body panel cutout. Thereby, the load by which the retractor is pulled upward is shared by the upper body panel. As a result, the load sharing of the retractor bracket can be reduced, and the thickness of the retractor bracket can be reduced to reduce the weight of the retractor bracket and reduce the number of welding points.

According to the retractor mounting device of ( 2 ) above, the upper edge of the upper body panel notch is located on the portion of the retractor facing the upper edge of the upper body panel notch when the retractor moves upward at the time of belt anchor evaluation or vehicle collision. Since the concave part that accepts is formed, when the retractor moves upward and the upper edge of the upper body panel notch enters the concave part of the retractor, such as when the vehicle collides, slipping and rotation between the retractor and the upper body panel are prevented or suppressed Is done.

According to the retractor attachment device of ( 3 ) above, the reinforcement is arranged, and the reinforcement is attached to any one of the upper body panel, the rear pillar, and both the upper body panel and the rear pillar. The movement of the retractor can be suppressed by the reinforcement without increasing the thickness of the upper body panel or the rear pillar.

[Example 1]
A retractor mounting device 10 according to a first embodiment of the present invention is a retractor mounting device for a seat belt 70 for a rear seat or an intermediate seat of a vehicle.
As shown in FIGS. 1 and 2, the retractor mounting device 10 comprises a side portion of a vehicle body from an outer panel 12 and an inner panel 13, and a part of the inner panel 13 is cut away between the outer panel 12 and the outer panel 12. An accommodation portion for accommodating the retractor 60 of the seat belt 70 is provided, and the retractor 60 is attached to the inner panel 13 via the retractor bracket 50 at a position where the retractor 60 is wrapped with the upper edge 22 of the notch 21 provided in the inner panel 13 in the vehicle width direction. Consists of a mounting structure for a vehicle.
In the retractor mounting device 10, the retractor 60 and the upper edge 22 of the notch 21 are separated from each other.
The distance or gap D between the upper end of the retractor 60 and the upper edge 22 of the notch 21 is smaller than the amount D2 of upward movement of the retractor during belt anchor evaluation or vehicle collision. Conventionally, the gap D is larger than D2.

When the retractor mounting device 10 is a retractor mounting device for the rear seat belt 70 of the vehicle, the following structure is adopted.
That is, as shown in FIGS. 1 and 2, the retractor mounting device 10 includes an upper panel 20 having a notch 21 and an inner panel 13 having a lower body panel 30 connected to a lower end of the upper body panel 20, and A rear pillar 40 connected to the rear end of the upper body panel 20, a retractor 60 of a seat belt 70 for the rear seat disposed in a space surrounded by the edge of the notch 21 and the rear pillar 40, the upper body panel 20 and The retractor bracket 50 is connected to at least one member of the lower body panel 30 and the rear pillar 40 and is connected to the retractor 60 with a bolt.
A gap D is provided between the retractor 60 and the upper edge of the upper body panel cutout 21.
The clearance D is smaller than the amount of upward movement of the retractor 60 at the time of belt anchor evaluation or vehicle collision.

  More specifically, as shown in FIGS. 1 and 2, the retractor mounting device 10 includes an upper body panel 20 having a notch 21 at a lower rear end portion, and a lower body panel connected to a lower end portion of the upper body panel 20. 30 and a rear pillar 40 connected to the rear end portion of the upper body panel 20 and the rear end portion of the lower body panel 30. The upper body panel 20 and the lower body panel 30 are connected to each other at an intermediate position in the vehicle vertical direction. The rear pillar 40 extends in the vehicle vertical direction behind the upper body panel 20 and the lower body panel 30.

  The upper body panel 20, the lower body panel 30, the rear pillar 40, and the retractor bracket 50 are made of metal, for example. The upper body panel 20 is, for example, a roof side inner panel, the lower body panel 30 is, for example, a wheel house panel, and the rear pillar is, for example, a D pillar of a three-row seat vehicle or a C pillar of a two-row seat vehicle.

  A space 11 is formed between the lower rear end portion of the upper body panel 20 and the upper rear end portion of the lower body panel 30 and the rear pillar 40. The space 11 includes a space 11 a surrounded by the upper edge 22, the side edge 23, and the rear pillar 40 of the cutout 21 of the upper body panel 20, and a space 11 b between the lower body panel 30 and the rear pillar 40. Including.

  The retractor mounting device 10 is connected to the retractor 60 of the rear seat belt 70 disposed in the space 11 a and at least one member of the upper body panel 20, the lower body panel 30, and the rear pillar 40, and is connected to the retractor 60. And a retractor bracket 50.

  Connection between the lower end of the upper body panel 20 and the lower body panel 30, connection between the rear end of the upper body panel 20 and the rear pillar 40, and at least one member of the upper body panel 20, the lower body panel 30 and the rear pillar 40 And the retractor bracket 50 are connected by spot welding, for example. Reference numeral 80 denotes a spot welding spot. The welding hit points 80 include weld hit points 80a, 80b, 80c between the retractor bracket 50 and the peripheral panels 20, 30, 40, and a weld hit point 80d between the peripheral panels 20, 30, 40. The welding spot 80b is a spot common to the upper and lower body panels 20 and 30.

  A front end portion of the retractor bracket 50 is connected to at least one member of the upper body panel 20 and the lower body panel 30 by spot welding and extends rearwardly into the space 11. The retractor 60 is disposed in the space 11 a and is disposed between the upper edge 22 of the notch 21 of the upper body panel 20 and the upper end portion of the retractor bracket 50 in the vertical direction. The retractor 60 is connected to the upper end of the retractor bracket 50.

  The connection between the retractor 60 and the retractor bracket 50 is, for example, a connection using a bolt 90. Although it is a bolt connection, since a claw is provided in one of the retractor 60 and the retractor bracket 50 and a hole is provided in the other and the claw is inserted into the hole, the retractor 60 and the retractor bracket 50 are rotated around the axis of the bolt 90 relative to each other. Does not move.

  The seat belt 70 is connected at one end to the retractor 60, extends upward from the retractor 60, is slidably inserted through the slip joint 91, is bent downward at the slip joint 91, and is connected to the anchor 92 at the other end. The slip joint 91 can be rotated around a bolt 93 fixed to the body. The seat belt 70 restrains the occupant's chest seated in the rear seat between the slip joint 91 and the anchor 92. The seat belt 70 pulls the retractor 60 upward in response to a load ahead of the rear seat occupant during a vehicle collision. At the time of belt anchor evaluation, the retractor 60 and the anchor 92 are evaluated by applying the load applied to the seat belt 70 at the time of a vehicle collision to the seat belt 70 as a test load. The load applied to the retractor 60 during the belt anchor evaluation coincides with the load applied to the retractor 60 during a vehicle collision.

  A gap space exists between the upper portion of the retractor 60 and the upper edge 22 of the upper body panel cutout 21. The clearance dimension D between the upper part of the retractor 60 and the upper edge 22 of the upper body panel notch 21 is necessary to absorb manufacturing errors including assembly errors of the upper body panel 20, the lower body panel 30, and the retractor bracket 50. Further, it is set to a dimension D1 or more necessary for preventing abnormal noise from being generated, and is set to be smaller than the amount of movement D2 upward of the retractor 60 at the time of belt anchor evaluation or vehicle collision.

  When the retractor 60 is pulled upward by the seat belt 70 at the time of belt anchor evaluation or vehicle collision, the retractor 60 moves upward from the initial position due to deformation of the retractor bracket 50 and deformation of the panels 20 and 30 to which the retractor bracket 50 is attached. To do. The amount of upward movement of the retractor 60 at the time of belt anchor evaluation or vehicle collision refers to the upward movement of the retractor 60 when the retractor 60 is pulled upward with a predetermined load by the seat belt 70 at the time of belt anchor evaluation or vehicle collision. This is the amount of movement.

D1 is, for example, about 5 mm (for example, 5 mm ± 2.5 mm), and D2 is, for example, about 10 mm (for example, 10 mm ± 5 mm). However, D1 is not limited to about 5 mm and D2 is not limited to about 10 mm, but is a value that varies depending on the design of the vehicle. The reason why D ≧ D1 is to maintain good assembly of the retractor 60, and the reason why D ≦ D2 is that the load is distributed by attaching the retractor 60 to the upper body panel 20 at the time of belt anchor evaluation or vehicle collision. It is to do.
The above configuration is not limited to the first embodiment of the present invention shown in FIG. 1 and FIG. 2, but is a modification of the first embodiment of the present invention shown in FIG. 3 and the other embodiment of the present invention shown in FIG. The present invention can also be applied to the embodiments.

As shown in FIGS. 1 and 2, the first embodiment of the present invention further has the following configuration.
The retractor bracket 50 is connected to the upper body panel 20 and the lower body panel 30 by spot welding. The retractor bracket 50 is not spot welded to the rear pillar 40. The retractor bracket 50 extends rearward from the upper body panel 20 and the lower body panel 30 to the space 11 and is fixed to the upper body panel 20 and the lower body panel 30 in a cantilever state.

  Since the retractor 60 that moves upward at the time of the belt anchor evaluation or the vehicle collision is attached to the upper body panel 20 and shares the load to the upper body panel 20, the upward load applied to the retractor bracket 50 from the retractor 60 is higher than that of the conventional case. As a result, the number of welding points between the retractor bracket 50 and the peripheral panels 20 and 30 is reduced as compared with the conventional case, and / or the thickness of the retractor bracket 50 is reduced as compared with the conventional case.

  For example, the sum of the number of welding points 80 between the retractor bracket 50 and the upper body panel 20 and the number of welding points 80 between the retractor bracket 50 and the lower body panel 80 is the number of welding points between the conventional retractor bracket and the peripheral panel. Smaller than. Although the conventional number of welding points is about 6, in the present invention, it is 6 points or less, for example, about 3 points 80a, 80b, and 80c. In FIG. 1, a welding spot 80 b is a welding spot common to the upper body panel 20 and the lower body panel 30.

  Moreover, the plate | board thickness of the retractor bracket 50 can also be made thin compared with the past. When the upward load applied to the retractor bracket 50 becomes 1 / N due to load sharing, the thickness of the retractor bracket 50 can be reduced to approximately 1 / N compared to the conventional case. The weight of the retractor bracket 50 is also reduced proportionally. Here, N is a number of 1 or more, for example, a number of 1 or more and about 3 or less. When N is 1, the plate thickness of the retractor bracket 50 remains the same as the conventional one.

  As shown in FIG. 2, a bent portion 24 is formed at the lower end portion of the upper body panel 20, thereby increasing the rigidity and strength of the lower end portion of the upper body panel 20 as compared with the case where the bent portion 24 is not formed. Is done. The bent portion 24 is bent, for example, from the general portion of the upper body panel 20 in a direction away from the seat belt 70, and is bent downward from the tip thereof. The general part of the upper body panel 20 is a part other than the bent part 24. The distance between the lower end 24a of the bent portion 24 and the upper end of the retractor 60 at the time of belt anchor evaluation or normal time not during a vehicle collision is a dimension D as shown in FIG. At the time of the belt anchor evaluation or the vehicle collision, as shown in FIG. 2B, D becomes 0, and the retractor 60 bottoms at the lower end 24a of the bent portion 24.

Next, the operation and effect of the first embodiment will be described with reference to FIGS.
First, since the clearance dimension D between the retractor 60 and the upper edge 22 of the notch 21 is set to be smaller than the amount D2 of upward movement of the retractor 60 at the time of belt anchor evaluation or vehicle collision, at the time of belt anchor evaluation. Alternatively, when the retractor 60 is pulled by the seat belt 70 and moves upward during a vehicle collision, the retractor 60 contacts the upper edge 22 of the notch 21. Thereby, a part of the load that pulls the retractor 60 upward is shared by the upper body panel 20, and the rest is received by the retractor bracket 50. As a result, the load received by the retractor bracket 50 can be reduced, and the thickness of the retractor bracket 50 can be reduced to reduce the weight of the retractor bracket 50 compared to the conventional case where the retractor bracket receives the full load of the retractor. And the number of welding points 80 with the peripheral panel of the retractor bracket 50 can be reduced.
The above operations and effects are also applied to the modification of the first embodiment of the present invention shown in FIG. 3 and the other embodiments of the present invention shown in FIGS.

In the first embodiment of the present invention shown in FIGS. 1 and 2, the following actions and effects can be obtained.
When D is set to about 1 / N of D2, and the load applied to the retractor bracket 50 is about 1 / N during belt anchor evaluation or vehicle collision, welding of the retractor bracket 50 and the peripheral panels 20 and 30 is performed. The number of hit points can be reduced to about 1 / N of the conventional number of weld points, and the thickness of the retractor bracket 50 can be reduced to 1 / N compared to the conventional case. Here, N is 2, for example. As a result, the welding cost between the retractor bracket 50 and the peripheral panel can be reduced substantially in proportion to 1 / N, and the weight and material cost of the retractor bracket 50 can also be reduced in proportion to 1 / N.

  Since the bent portion 24 is formed at the lower end portion of the upper body panel 20, the rigidity and strength of the notched upper edge 22 of the upper body panel 20 are increased as compared with the case where the bent portion 24 is not provided, and belt anchor evaluation is performed. It is possible to withstand the contact of the retractor 60 with the upper edge 22 of the notch at the time of a vehicle collision. Therefore, even if a part of the load is shared by the upper body panel 20, it is not necessary to increase the thickness of the upper body panel 20 compared to the conventional thickness of about 0.7 mm.

[Modification of Example 1]
In the first embodiment of the present invention shown in FIGS. 1 and 2, the case where the retractor bracket 50 is connected to both the upper body panel 20 and the lower body panel 30 by spot welding is shown. The attachment to the member may be replaced with the modification shown in (a), (b), and (c) of FIG.

  3, (a) shows the case where the retractor bracket 50 is attached to the upper body panel 20 by spot welding, (b) shows the case where the retractor bracket 50 is attached to the lower body panel 30, and (c) shows the retractor bracket 50. Are respectively attached to the lower body panel 30 and the rear pillar 40 by bridging.

  The actions and effects of the modified examples of (a), (b), and (c) in FIG. 3 are that the degree of freedom of design and structure that the retractor bracket 50 can take is improved.

[Example 2]

Modification 2 of the present invention further has the following configuration, operation, and effect.

4 (a) and 4 (b) show Embodiment 2 of the present invention. However, the outer panel is omitted. In the second embodiment of the present invention, when the retractor 60 moves upward at the time of the belt anchor evaluation or the vehicle collision, the upper body panel notch 21 of the retractor 60 faces the upper edge 22 of the upper body panel notch 21. A recess 61 for receiving the upper edge 22 is formed. The recess 61 is formed in the retractor side wall 62. The depth of the recess 61 is smaller than D. The distance between the bottom of the recess 61 and the upper edge 22 of the upper body panel notch 21 is D.
At the time of belt anchor evaluation or vehicle collision, the retractor 60 moves upward. A load that pulls the retractor 60 upward when the upper edge 22 of the upper body panel notch 21 and the bottom of the recess 61 come into contact with each other is shared by the upper body panel 20.

  Further, when the retractor 60 moves upward and the upper edge 22 of the upper body panel cutout 21 enters the recess 61 of the retractor 60 such as when a vehicle collides, the surface of the upper body panel 20 between the retractor 60 and the upper body panel 20 is orthogonal. Slipping or rotating in the direction of the movement is prevented or suppressed. As a result, the load applied to the retractor bracket 50 from the retractor 60 and / or the torsional load in the direction perpendicular to the surface of the retractor bracket 50 is suppressed, and the deformation of the retractor bracket 50 is suppressed.
