Summary of the Invention

Problems to be Solved by the Invention

[0005] In the pull handle disclosed in Patent Document 1, the bottom wall portion faces the wall surface in the vertical direction, and it is difficult to be crushed against the vehicle width direction load at the time of side impact. Further, due to the mounting seat portion, the bottom wall portion is more difficult to be crushed. Therefore, the pull handle of Patent Document 1 may be adversely affected by the impact absorption performance at the time of side impact.

Means for Solving the Problems

[0006] A pull handle for a vehicle door according to one aspect of the present invention made to solve at least one of the above problems is a pull handle for a vehicle door attached to a door trim disposed on the passenger compartment side of a vehicle door panel, It includes a bottom wall portion and a standing wall portion that rises from at least the edge on the passenger compartment side of this bottom wall portion and where a passenger's finger can be hooked. On the above bottom wall portion, a mounting seat portion used for fixing to the above door panel or the above door trim is formed so as to bulge downward. It is characterized in that a thin-walled portion connecting from this mounting seat portion to the edge of the above bottom wall portion is formed on the above bottom wall portion.

[0007] According to the above configuration, the thin-walled portion formed on the bottom wall portion breaks during a side impact and becomes a trigger for the bottom wall portion to collapse. Since the thin-walled portion connects from the mounting seat portion to the edge of the bottom wall portion, the degree of weakening of the bottom wall portion can be improved. Thereby, the impact absorption performance during a side impact can be improved.

[0008] Preferably, the above thin-walled portion has a portion extending along the vehicle length direction and a portion extending along the vehicle width direction. According to the above configuration, since the thin-walled portion has a portion extending along the vehicle length direction that becomes a trigger for folding in the vehicle width direction and a portion extending along the vehicle width direction that becomes a trigger for folding in the vehicle length direction, it can contribute to improving the degree of weakening of the bottom wall portion.

[0009] Preferably, the above bottom wall portion having the above mounting seat portion and the above thin-walled portion is provided, a first member having an insertion hole formed at the edge of the above bottom wall portion, and a second member having the above standing wall portion and an insertion piece protruding from the above standing wall portion are provided. This second member is attached to the first member in a state where the above insertion piece is inserted into the above insertion hole, and the thin-walled portion of the bottom wall portion of the first member connects from the above mounting seat portion to the above insertion hole. According to the above configuration, since the thin-walled portion connects from the mounting seat portion to the insertion hole which is a weak portion in the bottom wall portion, it can contribute to improving the degree of weakening of the bottom wall portion.

[0010] Preferably, the above mounting seat portion has a bottom plate portion and a cylindrical portion with a through hole formed therein, and the above thin-walled portion is continuous with the through hole of this cylindrical portion. According to the above configuration, the punching hole makes the mounting seat portion vulnerable to breakage, and by connecting the punching hole and the thin-walled portion, it is possible to contribute to an improvement in the degree of weakening of the bottom wall portion.

Effect of the Invention

[0011] According to the present invention, the impact absorption performance of the pull handle can be improved.

[0033] At the lower end portion of the standing wall portion 41, as shown in FIGS. 3 and 4(B), three engaging piece portions 43 are provided to project downward corresponding to the engaging holes 31 (FIG. 4(C)) of the pull handle core material 30, and the plate surfaces are oriented in the vehicle width direction. A claw portion 43a is provided on the passenger compartment side of the base end portion of the engaging piece portion 43.

[0034] On the surface of the standing wall portion 41 on the passenger compartment side, as shown in FIG. 4(B), two engaging piece portions 44 are provided to project downward corresponding to the engaging holes 33 (FIGS. 3 and 4(C)) of the pull handle core material 30, and the plate surfaces are oriented in the vehicle width direction. A claw receiving hole 44a is formed in the engaging piece portion 44.

[0035] In the flange portion 42, as shown in FIG. 3, two rectangular positioning holes 45 are formed corresponding to the positioning protrusions 36 of the pull handle core material 30.

[0036] (Connection between the grip member and the pull handle core material) As shown in FIGS. 4(A) and 5, the grip member 40 is connected to the pull handle core material 30. By bringing the grip member 40 closer to the pull handle core material 30 from above and outside the passenger compartment, the engaging piece portion 43 of the grip core material 40 is inserted into the engaging hole 31 of the pull handle core material 30. At this time, as shown in FIGS. 4(A) and 5(A), the claw portion 43a of the engaging piece portion 43 engages with the claw receiving piece portion 32 of the engaging hole 31.

[0037] At the same time, the engaging piece portion 44 is inserted into the engaging hole 33. At this time, as shown in FIGS. 4(A) and 5(B), the claw portion 34 at the edge of the engaging hole 33 engages with the claw receiving hole 44a of the engaging piece portion 44. When the connected state shown in FIG. 4(A) is achieved in this way, the positioning projection 36 of the pull handle core member 30 fits into the positioning hole 45 of the grip member 40, and the grip member 40 and the pull handle core member 30 are positioned.

[0038] In the pull handle 5 constituted by connecting the grip member 40 and the pull handle core member 30, the standing wall portion 41 of the grip member 40 rises from the edge portion on the vehicle interior side to the vehicle rear side in the bottom wall portion 30a of the pull handle core member 30.

[0039] (Connection between the pull handle and the armrest core member) The pull handle 5 having the above configuration is connected to the armrest core member 20 as shown in FIG. 1(B).

The bracket 6 is L-shaped and integrally has a substantially vertical panel side portion 6a and a substantially horizontal vehicle interior side portion 6b. The panel side portion 6a is joined to the door panel 2 by screws 7 and screw grommets 7a. The vehicle interior side portion 6b is applied to the lower surface of the bottom plate portion 38b of the mounting seat portion 38 of the pull handle core member 38. A screw 8 passed through the through hole 38y of the bottom plate portion 38b is screwed into the vehicle interior side portion 6b. Thereby, the pull handle 5 is joined to the bracket 6 and thus connected to the door panel 2.

[0041] (Weakening structure of the pull handle) When a load F in the vehicle width direction shown in Fig. 1(A) is applied to the pull handle 5 with the above-described configuration and the occupant hits it during a side collision, the pull handle 5 has a structure that is easily crushed. As shown in Figs. 5 and 6, the bottom wall portion 30a of the pull handle core material 30 is slightly bent in the vehicle width direction, and is slightly inclined so that the vehicle interior side portion and the vehicle exterior side portion are convex downward. As shown in Fig. 6(A), an R portion 39 extending in the vehicle length direction is formed at the intersection of the vehicle interior side portion and the vehicle exterior side portion on the upper surface of the bottom wall portion 30a. The R portion 39 forms a curved surface that slightly curves as it proceeds in the vehicle width direction. The R portion 39 may be formed on the lower surface of the bottom wall portion 30a, or may be formed on both the upper and lower surfaces. This R portion 39 can serve as a trigger for the bottom wall portion 30a to fold in the vehicle width direction during a side collision.

[0042] Also, as shown in Fig. 6, a thin portion 50 that connects from the mounting seat portion 38 to the edge of the bottom wall portion 30a is formed on the bottom wall portion 30a. The thin portion 50 is formed so as to cut the lower surface of the bottom wall portion 30a, and may have thin portions 51, 55 extending along the vehicle length direction and thin portions 52, 53, 54 extending along the vehicle width direction. The thin portion 50 may be formed so as to cut the upper surface of the bottom wall portion 30a.

[0043] One end of the thin portion 51 is connected to the relief hole 38x on the front side of the mounting seat portion 38. The thin portion 51 extends from that one end toward the front of the vehicle, and is slightly inclined toward the vehicle interior side as it proceeds forward. The thin portion 51 extends to the front of the most front engaging hole 31 in the vehicle length direction and extends to a position beyond the R portion 39 in the vehicle width direction.

[0044] One end of the thin portion 52 is connected to the other end of the thin portion 51. The thin portion 52 extends from that one end toward the vehicle interior side, and is slightly inclined toward the front of the vehicle as it proceeds toward the vehicle interior side. The other end of the thin portion 52 is connected to the most front engaging hole 31.

[0045] One end of the thin-walled portion 53 is connected to the middle portion of the thin-walled portion 51. The thin-walled portion 53 extends from one end thereof toward the passenger compartment side beyond the R portion 39, and the other end thereof is connected to the second engaging hole 31 from the front.

[0046] One end of the thin-walled portion 54 is connected to the cylindrical portion 38a on the passenger compartment side of the mounting seat portion 38. The thin-walled portion 54 extends from one end thereof toward the passenger compartment side beyond the R portion 39, and the other end thereof is connected to the rearmost engaging hole 31.

[0047] One end of the thin-walled portion 55 is connected to the relief hole 38x on the rear side of the mounting seat portion 38. The thin-walled portion 55 extends from one end thereof toward the rear of the vehicle, and is inclined toward the passenger compartment side as it advances rearward. The thin-walled portion 55 extends beyond the R portion 39 in the vehicle width direction, and the other end thereof is connected to the lower end of the relief hole 35 formed at the intersection of the rear portion of the support wall portion 30b and the bottom wall portion 30a.

[0048] A thin-walled portion 60 is formed on the rear portion of the support wall portion 30b so as to cut the rear surface of the support wall portion 30b, and may be formed so as to cut the front surface. The thin-walled portion 60 extends upward from the upper end of the relief hole 35 to the upper end of the support wall portion 30b.

[0049] (Effects of the present embodiment) According to the pull handle 5 having the above configuration, the thin-walled portion 50 formed in the bottom wall portion 30a can break during a side collision and serve as a trigger for the bottom wall portion 30a to collapse. The thin-walled portion 60 formed in the support wall portion 30b can break during a side collision and serve as a trigger for the support wall portion 30b to collapse. Since the thin-walled portion 50 is connected from the mounting seat portion 38 to the edge portion of the bottom wall portion 30a, the bottom wall portion 30a is weakened. Since the thin-walled portion 60 and the relief hole 35 are connected from the upper end to the lower end of the support wall portion 30b, the support wall portion 30b is weakened. In particular, the thin portions 51 and 55 lead to the relief holes 38x which are the weak portions of the mounting seat portion 38, the thin portions 52, 53, and 54 lead to the engagement holes 31 which are the weak portions of the bottom wall portion 30a, and the thin portion 55 leads to the relief hole 35 which is the weak portion of the intersection of the bottom wall portion 30a and the support wall portion 30b, whereby the bottom wall portion 30a is weakened. In the thin portion 50, the thin portions 51 and 55 extending along the vehicle length direction can serve as a trigger for folding in the vehicle width direction, and the thin portions 52, 53, and 54 extending along the vehicle width direction can serve as a trigger for folding in the vehicle length direction.

[0050] According to the above embodiment, the shock absorption performance of the pull handle 5 can be improved.

[0051] Next, another embodiment of the present invention will be described. For the following embodiments, only the configurations different from the above embodiment will be described, and the same reference numerals will be given to the same components and their descriptions will be omitted.
