The present invention is also a structure for mounting an assist grip arranged in a vehicle compartment of a vehicle on a panel of a vehicle body, wherein the panel is provided with a fixing portion to which the assist grip is attached and surrounding the fixing portion. And a deformable weak body part.

The present invention also has a structure in which an assist grip arranged in a vehicle compartment of an automobile is attached to the panel via a bearing member which is attached to a panel of a vehicle body by a bolt, and is spaced from the head of the bolt. A cap that is attached to the bearing member so as to cover the head portion and an absorber that is disposed in the gap and that can absorb energy due to a load are provided.

In a preferred embodiment, the absorbent body is integrally provided with the cap.

In another preferred aspect, the absorber is integrally provided with the bearing member.

The present invention also has a structure in which an assist grip arranged in a vehicle interior of an automobile is attached to a panel of a vehicle body which is covered with an interior material inwardly, the assist grip including a grip portion and a grip portion of the grip portion. A mounting portion provided on each of the two ends and mounted to the panel by a bolt, wherein the interior material is spaced from the panel, and the two mountings of the assist grip. Each of the parts has a hole penetrating therethrough, and a cap attached to each hole so as to cover the head of the bolt and capable of absorbing energy due to a load.

[0016]

[Operations and Effects] When the assist grip is separable, the assist grip is separated from the panel when a load larger than a predetermined value is applied from the head of the occupant. By this separation, the impact energy due to the load can be absorbed and the impact on the head can be mitigated. Further, the assist grip is separated toward the outside in the width direction of the vehicle body, and the assist grip is in a so-called depressed state, so that a sharp edge due to cracking or deformation is less likely to occur in the assist grip.

The assist grip is separable and has a grip portion and a mounting portion provided at each of two ends of the grip portion, and the panel has a hole through which each mounting portion penetrates and a receiving portion. When the assist grip is attached with a screw, the assist grip can be positioned by the hole of the panel and the receiving portion, so that the workability of attaching the assist grip is good. Further, since the assist grip is separated from the screw, the impact energy due to the load can be further absorbed due to the deformation of the receiving portion, so that the energy absorption effect can be enhanced. Also,
Energy can be absorbed without increasing the protrusion length of the assist grip into the passenger compartment, and since the attachment part of the assist grip hits the outer surface of the panel and is attached to the panel, the pulling force applied to the assist grip is applied to the surface of the attachment part. You will be able to improve your durability.

When the assist grip is separable, the panel is an inner panel of a roof side rail, and the interior material has a notch for temporarily placing the interior material on the assist grip, the assist grip is attached to the panel, After that, the interior material is attached, but the workability can be improved because the interior material can be temporarily placed on the assist grip when attaching the interior material.

When the assist grip is attached to the panel by the bolt and the breakable nut, the nut breaks when a load larger than a predetermined value is applied to the bolt. By this breakage, the impact energy due to the load can be absorbed and the impact on the head of the occupant can be mitigated. Further, since the bolt holes are only formed in the panel and the nut is fixed to the panel, the breaking load of the nut can be changed and the energy absorption performance can be adjusted without substantially impairing the rigidity of the panel. Further, since the assist grip and the panel are not substantially changed, the conventional one can be used as it is, and the procedure for attaching the assist grip can be the same as the conventional procedure.

If the assist grip is attached to the panel by a bolt and a breakable nut and has an absorber or elastic collar, the absorber or collar deforms as the assist grip moves after the nut breaks. . Therefore, energy can be absorbed in two stages, and the effect of energy absorption can be enhanced. Also,
The energy absorbing load when the assist grip moves after the nut breaks can be controlled by the absorber or the collar.

When the panel has a fixed portion to which the assist grip is attached and a weak body portion surrounding the fixed portion, the fixed portion of the panel is deformed starting from the weak body portion when a load larger than a predetermined value is applied. By this deformation, the impact energy due to the load can be absorbed and the impact on the head of the occupant can be mitigated. In addition, the conventional assist grip can be used as it is.

The assist grip is attached to the panel via a bearing member attached to the panel by a bolt,
When the absorber is arranged within the gap between the head of the bolt and the cap, the absorber is deformed when a load larger than a predetermined value is applied.
By this deformation, the impact energy due to the load can be absorbed and the impact on the head of the occupant can be mitigated. Further, since the cap or the bearing member is inside the vehicle compartment, even if the cap or the bearing member is damaged as a result of energy absorption,
Easy to replace with new parts.

The assist grip has a grip portion and two mounting portions, the interior material is arranged at a distance from the panel, has a hole for penetrating the two mounting portions of the assist grip, and has a cap attached thereto. In this case, the cap is deformed when a load larger than a predetermined value is applied to the cap. By this deformation, the impact energy due to the load can be absorbed and the impact on the head of the occupant can be mitigated. Further, since the mounting portion of the assist grip is located outside the interior material and is covered with the interior material, it is not necessary to provide a convex mounting seat or a bracket on the panel. In addition, the design surface of the interior material, that is, the surface that appears in the vehicle interior, can be eliminated because of the protruding parts that are attached, so that the appearance can be improved. Further, another energy absorber can be easily arranged outside the interior material.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention has a structure in which an assist grip arranged in a vehicle cabin is attached to a vehicle body panel.
In the embodiment shown in FIGS. 1 to 8, the assist grip is detachably attached to the panel outward in the width direction of the vehicle body when a load larger than a predetermined value is applied.

1 to 3, the assist grip 20 includes an inner panel 22 of a roof side rail.
Is attached to.

The assist grip 20 has a grip portion 24 having a U-shaped planar shape, and a mounting portion 25 provided at two ends of the grip portion 24 at right angles and extending in mutually opposite directions.

The inner panel 22 is the assist grip 2
No. 0 has a fixing portion 27 having a hole 26 penetrating each mounting portion 25, and a deformable receiving portion 28 projecting from the inner panel 22 outward in the width direction of the vehicle body and receiving each mounting portion 25. In FIG. 1, the left side hole 26 and the right side hole 26 are symmetrical, and the right side hole 26 is opened so that the front shape has an L shape. On the other hand, the left-side receiving portion 28 and the right-side receiving portion 28 are symmetrical as shown in FIG. 2, and the right-side receiving portion 28 is formed so that the planar shape thereof is an inverted L shape. In the illustrated embodiment, the receiving portion 28
Are cut and raised when the hole 26 is opened.

The assist grip 20 has a mounting portion 25.
Is inserted into the hole 26 of the fixing portion 27 of the inner panel 22 and penetrated, the entire assist grip 20 is moved upward, each mounting portion 25 is brought into contact with the outer surface of the inner panel 22 removed from the hole, and the tapping screw 30 is applied. Panel 22
Through the hole 29, and is screwed into the hole 31 of the mounting portion 25 to be mounted on the inner panel 22. Hole 3 for mounting part 25
No. 1 has a smaller diameter than the tapping screw 30, and it is convenient to open it.

Here, the application of the mounting portion to the outer surface of the inner panel removed from the hole has the following meaning. When the two mounting portions 25 of the assist grip 20 extend in the same direction as the grip portion 24 when the assist grip 20 is viewed from the front as in the embodiment of FIG. 1, the mounting portion 25 is penetrated, and In order to move the entire assist grip 20 upward or downward so as to contact the outer surface of the inner panel 22, a portion having a size substantially the same as the mounting portion 25 and a portion smaller than the mounting portion 25, such as the hole 26. A hole having and is required, and in this case, being disengaged from the hole means being disengaged from a portion having substantially the same size as the mounting portion. On the other hand, the mounting portion 25 may extend in a direction perpendicular to the grip portion 24 when the assist grip 20 is viewed from the front, as indicated by a phantom line in FIG. 1. In this case, it suffices to make a hole of a size that allows the mounting portion 25 to pass through,
When the mounting portion 25 penetrating this hole is moved upward or downward, the mounting portion 25 can come into contact with the outer surface of the inner panel 22. Therefore, when moving from a hole portion or a hole having substantially the same size as the mounting portion 25, the mounting portion 2
5 will be removed from the hole.

The inner panel 22 is internally covered with an interior material. In the embodiment of FIGS. 1 to 3, the ceiling material 32
And the garnish 34 are covered with two interior materials. The ceiling material 32 of the interior material is provided with a notch 36 for temporarily placing the ceiling material 32 on the assist grip 20. The notch 36 is the notch 36

It is preferable to determine the position and shape so that the substantial positioning can be performed.

When the notch 36 is provided, after the assist grip 20 is attached to the inner panel 22, the ceiling material 32 is attached.
When attaching, the notch 36 of the ceiling material 32 is placed on the grip portion 24 of the assist grip 20 and temporarily placed, and the attachment work can be performed. After attaching the ceiling material 32, the garnish 34 is attached to cover the holes 26 of the inner panel 22.

As is apparent from the drawing, the tapping screw 30 is formed so that its screw portion has a conical shape. Therefore, as shown in FIG. 3, the fixing force is relatively small with respect to the load that attempts to move the assist grip 20 outward A in the width direction of the vehicle body. Will come out of the tapping screw 30. Therefore, when the head portion of the occupant collides with the grip portion 24 of the assist grip 20, if the load due to the collision is equal to or more than a predetermined value, the attachment portion 25 comes off from the tapping screw 30. Then, the assist grip 20 deforms the receiving portion 28 of the inner panel 22 and moves, so that the assist grip 20 is depressed into the inner panel 22. At this time, the impact energy is absorbed by the detachment of the mounting portion 25 and the deformation of the receiving portion 28. On the other hand, the mounting portion 25 of the assist grip 20 is not attached to the inner panel 22 at the portion out of the hole.
Since it hits the outer side surface of the vehicle, it has sufficient strength against a load directed inward B in the width direction of the vehicle body.
