TECHNICAL FIELD OF THE INVENTION
The present invention relates to an automobile door trim having an impact absorbing function on an armrest.
[0002]
[Prior art]
Conventionally, a door of an automobile is provided with a door trim for the purpose of decorating the interior of the vehicle compartment, and an armrest is protruded from the door trim toward the interior of the vehicle interior.
[0003]
For this reason, door trims have been proposed in which the armrest has a shock absorbing function in order to absorb the shock when the occupant collides with the armrest due to a side collision of the vehicle.
[0004]

[Patent Document 3]
JP 2000-103230 A (paragraphs 0005,0006)
[0005]
As shown in FIG. 5, the door trim described in Patent Literature 1 has a cutout groove c formed along a forming base of an armrest b protruding from the door trim a to the vehicle interior side. When an impact is applied in the direction of the arrow d, the armrest b is broken from the cutout groove c as shown in FIG. 6 to absorb the impact.
[0006]
Further, in the door trim described in Patent Document 2, the door trim and the armrest are formed as separate members, and the strength of the joint between the door trim and the armrest is set relatively weak. When an impact is applied to the armrest, the armrest falls off. It is configured to absorb shock.
[0007]
Further, the door trim described in Patent Document 3 has a lower breaking groove from the side surface to the outdoor position, and a lateral breaking from the lower breaking groove to a position higher than the upper surface, on the back side of the lower end position of the rear end surface of the armrest. When a shock is applied to the armrest by forming a groove for the armrest, the lower break groove and the lateral break groove are broken to absorb the shock.
[0008]
[Problems to be solved by the invention]
However, as in the door trim described in Patent Documents 1, 2, and 3, a notch groove or a break groove is formed in a continuous portion between the door trim and the armrest, and the strength of the joint is set to be relatively weak to generate an impact. In the case of absorbing, since the shock absorbing capacity differs depending on the break point, it is difficult to design so as to obtain the predetermined shock absorbing capacity, and since the break point cannot be specified, the reaction force tuning ( There are also problems such as difficulty in adjusting the reaction force).
[0009]
In addition, since the impact absorption points are set by means such as notch grooves, break grooves, weakening the joints, etc., if a strong shock is accidentally applied during use, the armrest will break or drop off from the door trim There are also problems such as.
[0010]
SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem. A door trim for an automobile having an armrest capable of absorbing a shock at the time of a collision, and having no fear of being damaged or falling off even when an impact is applied by mistake during use. The purpose is to provide.
[0011]
[Means for Solving the Problems]
To achieve the above object, a door trim of an automobile according to the present invention is a door trim of an automobile in which an armrest and a door trim main body are integrally molded with resin, and a door trim main body is mounted on an inner panel of the door to decorate a door interior side of the door. There is a cross section in which the armrest and the door trim main body are continuously connected to each other, the inner panel side is protruded, and one open end is continuously connected to the door trim main body, and the other open end is continuously connected to the armrest. An impact absorbing means formed by a substantially V-shaped ridge is provided.
[0012]
According to the above configuration, when an excessive impact is applied to the armrest when the vehicle side impacts, the ridge of the shock absorbing means provided in the continuous portion of the door trim main body and the armrest breaks from the ridge portion to absorb the impact, In addition to being able to mitigate the impact at the time of collision, the break point can be specified at the ridge of the ridge, so that it is easy to design according to the shock absorption capacity and adjust the reaction force easily. Become.
[0013]
Also, when using a car, even if a strong impact is applied to the armrest accidentally from the side or a strong impact is applied to the armrest due to accidentally dropping a heavy object, the ridge of the shock absorbing means expands and contracts and the impact is applied. Because it absorbs, the armrest is not damaged and does not fall off the door trim.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Embodiments of the present invention will be described in detail with reference to the drawings.
[0015]
1 is a perspective view of a door trim, FIG. 2 is a sectional view taken along line AA of FIG. 1, and FIGS. 3 and 4 are operation explanatory views.
[0016]
As shown in FIG. 2, a door 2 of an automobile to which the door trim main body 1 shown in FIG. 1 is mounted has a double structure including an outer panel 2a outside a vehicle body (not shown) and an inner panel 2b facing the passenger compartment. A bag 2c for accommodating door glass opening / closing means (not shown) and the like is formed between the outer panel 2a and the inner panel 2b, and a clip or the like is fixed to the inner panel 2b on the vehicle interior side. The door trim main body 1 is attached by means (not shown).
[0017]
The door trim body 1 is formed of a relatively hard resin into a panel shape, and is integrally formed so that an armrest 3 protrudes substantially toward the vehicle interior at a substantially central portion, and a pocket having an upper surface opened below the armrest 3. The part 4 is integrally formed.
[0018]
The armrest 3 is formed in a substantially boat-like shape elongated in the front-rear direction of the vehicle body by an upper surface portion 3a which is substantially flat and is gradually inclined downward toward the interior of the vehicle, and a side surface portion 3b which is curved in an arc shape between the upper surface portion 3a and the bottom surface 3c. Have been.
[0019]
The upper surface 3a of the armrest 3 is formed with a substantially elliptical concave portion 3d on which a hand is put when opening and closing the door 2, and a handle (not shown) for unlocking when opening the door 2 is provided in front of the armrest 3. Is formed in the vehicle compartment side.
[0020]
As shown in FIG. 2, an impact absorbing means 5 is provided at a continuous portion between the peripheral portion of the armrest 3 and the door trim main body 1.
[0021]
The shock absorbing means 5 includes a substantially V-shaped ridge 5b having a ridge 5a protruding toward the inner panel 2b, and is formed over the entire periphery of the armrest 3, and one of the ridges 5b. The open end is integrally connected to the door trim main body 1, and the other open end is integrally connected to the peripheral portion of the armrest 3.
