Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention particularly relates to an armrest structure for a vehicle door having a pull handle.
[0002]
[Prior art]
An armrest is formed on a door trim attached to a vehicle interior side of an automobile door so as to protrude toward the vehicle interior side. A pad is provided on the upper surface of the armrest so that the occupant's arm can be placed thereon. Further, an opening is formed at a position forward of the pad on the upper surface of the armrest, and a pull handle that is gripped when the door is opened and closed is attached to the opening. The pull handle is in the shape of a container with an open top, and the bottom portion is fixed inside the arm rest while being inserted into the opening of the arm rest from above (see JP-A-2000-52770 as a similar technique).
[0003]
The armrest having such a structure needs to be fragile in order to absorb an impact upon a vehicle side collision. Therefore, a portion of the armrest that is covered with the pad is provided with a notch, thereby reducing the strength of the armrest.
[0004]
[Problems to be solved by the invention]
However, in such a conventional armrest, a portion covered with a pad can be reduced in strength by a cutout formed inside, but a portion in which a pull handle is inserted has a pull handle opened at an upper portion. Because of the strength of the container, it was difficult to reduce the strength.
[0005]
The present invention has been made by paying attention to such a conventional technique, and provides an armrest structure of a vehicle door capable of reducing the strength of a portion to which a pull handle is attached.
[0006]
[Means for Solving the Problems]
The invention according to claim 1 is an armrest structure for a vehicle door, wherein an opening is formed in an upper surface of an armrest protruding from a door trim toward a vehicle interior, and a pull handle in the shape of an upper open container is mounted in the opening. The pull handle is divided into a vehicle exterior member and a vehicle interior member, and the vehicle interior member is engaged with the vehicle exterior member so as to be easily deformed to the vehicle exterior.
[0007]
According to the first aspect of the present invention, of the two divided pull handles, the inner member that hits the occupant in the event of a side collision is easily deformed to the outside of the vehicle, so that the strength of the portion to which the pull handle is attached also decreases. The impact can be absorbed by the deformation of this portion.
[0008]
According to a second aspect of the present invention, the vehicle interior member is mainly formed of a flat side surface forming the vehicle interior side surface of the pull handle, and the lower end of the side surface portion is formed at the vehicle interior end of the bottom surface portion of the vehicle exterior member. From the outside of the vehicle.
[0009]
According to the second aspect of the present invention, since the vehicle interior member is mainly composed of the flat side surface, the vehicle inner member is more easily deformed than the three-dimensional side surface. In addition, since the lower end thereof is only engaged with the projection on the bottom surface of the vehicle exterior member from the vehicle exterior, deformation toward the vehicle interior is prevented, and the rigidity required for closing the door is secured, while the vehicle is secured. The deformation to the outside is easy and absorbs the impact in the event of a side collision.
[0010]
According to a third aspect of the present invention, the front and rear ends of the vehicle interior member are engaged with the front and rear ends of the vehicle exterior member from the vehicle interior side, and the front and rear ends of the vehicle interior member are respectively adjacent to the front and rear inner portions from the lower end. A slit is formed.
[0011]
According to the third aspect of the present invention, since the slit is formed in the vehicle interior member, it is easier to deform.
[0012]
The invention according to claim 4 is an armrest structure for a vehicle door, wherein an opening is formed on an upper surface of an armrest protruding from a door trim toward a vehicle interior, and a pull handle in the shape of an open-top container is mounted in the opening. The pull handle is divided into an outer member and an inner member. The inner member includes a front part and a rear part whose inner angle is obtuse with respect to the side part from the front and rear ends of the side part forming the inner surface of the pull handle. Surface portions are respectively formed.
[0013]
According to the invention as set forth in claim 4, even if the vehicle interior member has a three-dimensional shape having a front portion and a rear surface portion in front and rear of the side portion, it is deformed so as to be crushed at the time of a side collision because of the horizontal cross-sectional shape opened at an obtuse angle. Easy to do.
[0014]
According to the fifth aspect of the present invention, the vehicle interior member has a bottom surface having an obtuse angle with respect to the side surface from the lower end of the side surface forming the vehicle interior surface of the pull handle.
[0015]
According to the fifth aspect of the invention, even when the vehicle interior member has a three-dimensional shape having a bottom surface portion at the lower end of the side surface portion, the vehicle interior member is easily deformed so as to be crushed at the time of a side collision because of the vertical cross-sectional shape opened at an obtuse angle.
[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
[0017]
1 to 4 are views showing a first embodiment of the present invention. FIG. 1 shows a door 1 on the right side, and a door trim 2 made of resin is mounted on the vehicle interior side. The door trim 2 is formed with an armrest 3 protruding toward the vehicle interior. A pad 4 on which the occupant's arm rests is provided behind the upper surface of the armrest 3.
[0018]
An opening 5 (see FIG. 3) is formed in the upper surface of the armrest 3 in front of the pad 4, and a pull handle 6 in the shape of an open-top container is mounted therein. The pull handle 6 is a portion that the occupant grasps by hand for opening and closing the door 1. Various switches 7 are provided further on the front side of the pull handle 6.
[0019]
The pull handle 6 has an open-top container shape as a whole, but is composed of two parts, an outer member 8 and an inner member 9. The vehicle exterior member 8 has a container shape that lacks only a portion of the pull handle 6 that becomes the vehicle interior side surface, and an enlarged step portion 10 is formed at the upper edge. In addition, a mounting seat 12 is formed on the bottom surface portion 11 of the vehicle outer member 8 so as to be one step lower. Further, an upwardly protruding portion 13 is formed at a center position of the inner side end of the bottom surface portion 11 of the outer side member 8.
[0020]
At the upper part of the vehicle interior member 9, there is provided a ring portion 14 fitted to the step portion 10 of the vehicle exterior member 8, and a peripheral flange 15 formed from the upper end thereof and placed around the opening 5. The interior side of the ring portion 14 extends downward as a flat plate-shaped side portion 16 forming the interior surface of the pull handle 6, and a projecting piece 17 is formed at the lower end thereof to engage the projection 13 from outside the vehicle. ing.
[0021]
The front and rear end portions 16a and 16b of the side surface portion 16 are stepped toward the vehicle interior so as to engage with the front and rear front and rear end portions of the vehicle exterior member 8 from the vehicle interior side. In addition, slits 18 are formed from the lower ends of the side surface portion 16 at portions adjacent to the front and rear end portions 16a and 16b in the front and rear direction.
[0022]
Therefore, the vehicle interior member 9 is engaged with the vehicle exterior member 8 from above, the ring portion 14 is fitted to the step portion 10, and the projection 17 at the lower end of the vehicle interior member 9 is engaged with the projection of the vehicle exterior member 8. 13 from outside the vehicle. Then, the attachment portion 19 (see FIG. 2) of the ring portion 14 and the step portion 10 is attached to each other with screws (not shown), so that the vehicle interior member 9 and the vehicle exterior member 8 become an integrated pull handle 6. The integrated pull handle 6 is inserted into the opening 5 of the armrest 3, and the mounting seat 12 of the bottom surface portion 11 is fixed to the inside of the armrest 3 with the clip 20.
[0023]
The pull handle 6 thus attached is located in the opening 5, and the projection 17 at the lower end of the vehicle interior member 9 engages with the projection 13 of the vehicle exterior member 8 on the vehicle exterior. Therefore, rigidity required for opening and closing the door 1, particularly rigidity in a pulling direction required for closing the door 1, is secured.
[0024]
Further, at the time of a side collision of the vehicle, the door 1 relatively moves to the occupant side, the occupant hits the armrest 3, and an impact F due to the occupant hitting the armrest 3 is applied. However, since the vehicle interior member 9 that contacts the occupant is mainly composed of the flat side surface portion 16, the vehicle interior member 9 is easily deformed as compared with the case of forming a three-dimensional shape, and absorbs the impact F. In addition, the lower end has only the projection 17 engaged with the outer side of the projection 13 of the outer side member 8 and also has slits 18 formed on both front and rear sides. As shown in FIG. 3, the portion 16 is largely deformed so that the whole thereof rotates outwardly around the upper portion integrated with the ring portion 14, and finally deformed as shown in FIG. It enters the inside of the vehicle outer member 8 as it is. Therefore, the impact F absorbing performance is high and the occupant protection effect is excellent.
[0025]
FIG. 5 is a diagram showing a second embodiment of the present invention. The pull handle 21 of the second embodiment is also divided into a vehicle outer member 22 and a vehicle inner member 23. Flanges 26 are bent from the upper ends of the front part 24 and the rear part 25 of the vehicle outer member 22, respectively. A mounting seat 28 is formed at the center of the bottom surface 27, and a protrusion 29 is formed at an end on the vehicle interior side. Further, a fastening hole 30 is formed in the front part 24, and a fastening piece 31 is formed in the rear part 25.
[0026]
On the other hand, similarly to the first embodiment, the vehicle interior member 23 mainly includes a flat side surface portion 32, and a flange 33 is formed at an upper end. Slits 34 are also formed on both front and rear sides of the side surface portion 32. A fastening piece 35 bent outward is formed at the front end of the side surface portion 32, and a fastening piece 36 extending rearward is formed at the rear end. The reason why the front fastening piece 35 faces the outside of the vehicle is to avoid interference with the wiring of the switches and the board in front of the fastening piece 35.
[0027]
The vehicle interior member 23 having the above-described shape is set from the upper side of the vehicle exterior member 22, and the lower end thereof is engaged with the vehicle exterior of the protruding portion 29. By fastening the corresponding fastening pieces 31 and 36 on the rear side with clips (not shown), the vehicle exterior member 22 and the vehicle interior member 23 are integrated to form the pull handle 21.
[0028]
The "fastening means" of the second embodiment is formed by the fastening holes 30, the fastening pieces 31, 35, and the clips (not shown). This "fastening means" has low strength and is easily broken by an impact at the time of a side collision.
[0029]
According to the second embodiment, since the vehicle interior member 23 is fastened to the vehicle exterior member 22, the pull handle 21 with a more sense of unity is formed. In addition, since the fastening means is easily broken at the time of a side collision, the deformation of the vehicle interior member 23 to the vehicle outside is not obstructed, and the shock due to the deformation can be reliably absorbed. Other functions and effects are the same as those of the first embodiment.
[0030]
6 to 10 are views showing a third embodiment of the present invention. Also in the third embodiment, the pull handle 37 is divided into two parts. However, both the vehicle exterior member 38 and the vehicle interior member 39 have a three-dimensional shape.
[0031]
The vehicle interior member 39 has a three-dimensional shape in which a front surface portion 41 is formed at a front end of a side surface portion 40, a rear surface portion 42 is formed at a rear end, and a bottom surface portion 43 is formed at a lower end. The peripheral flange 44 and the ring portion 45 fitted to the vehicle outside member 38 are formed on the vehicle inside member 39, respectively.
[0032]
In the vehicle interior member 39, the angles of the front surface portion 41, the rear surface portion 42, and the bottom surface portion 43 with respect to the side surface portions 40 are all obtuse angles θ larger than a right angle. Therefore, the vehicle interior member 39 has a cross-sectional shape that is open at an obtuse angle θ in both a horizontal cross section (see FIG. 7) and a vertical cross section (see FIG. 8).
[0033]
A mounting seat 46 is also formed on the bottom surface 43 of the vehicle interior member 39, but as shown in FIG. 9, when a load greater than the strength required for fixing to the armrest is applied, the mounting seat 46 is formed. Three notches 47 are formed in the peripheral edge of the mounting seat 46 so that is broken from the vehicle interior member 39.
[0034]
Further, as shown in FIG. 10, a thin portion 49 is formed along the ridge line portion 48 on the ridge line portion 48 which is a boundary between the side surface portion 40, the front surface portion 41, the rear surface portion 42, and the bottom surface portion 43. Is formed.
[0035]
The outer member 38 corresponding to the inner member 39 also has a shape corresponding to the inner member 39. A front part 51 and a rear part 52 are formed at an obtuse angle θ before and after the side part 50, and at the lower end. The bottom surface portion 53 is formed at an obtuse angle θ. A step portion 54 is formed at the upper end of the vehicle outer member 38, and a semicircular rib 55 that engages with the mounting seat 46 is formed at a lower end of the bottom surface portion 53.
[0036]
By integrating the vehicle exterior member 38 having such a shape and the vehicle interior member 39, a pull handle 37 having a hexagonal horizontal cross section is formed. The upper end of the pull handle 37 is positioned by engaging the ring portion 45 with the step portion 54, and the lower end is positioned by engaging the mounting seat 46 with the semicircular rib 55.
[0037]
According to the third embodiment, even if the vehicle interior member 39 and the vehicle exterior member 38 have a three-dimensional shape, each has a cross-sectional shape opened at an obtuse angle θ in the horizontal cross section and the vertical cross section. , The pull handle 37 is deformed so as to be crushed. In particular, since the thin portion 49 is also formed on the ridge line portion 48 on the vehicle interior member 39 side, the vehicle interior member 39 is further easily crushed. Therefore, the impact at the time of a side collision is more reliably absorbed, and the occupant protection performance is improved.
[0038]
In addition, since the mounting seat 46 is broken, the pull handle 37 moves to the outside of the vehicle, leaving only the mounting seat 46 crushed. Therefore, the pull handle 37 can absorb the impact not only by “crushing” but also by “moving”, and the occupant protection performance in the event of a side collision is further improved.
[0039]
【The invention's effect】
According to the present invention, of the two divided pull handles, the inner member that hits the occupant particularly in the event of a side collision is easily deformed to the outer side, so that the strength of the portion to which the pull handle is attached also decreases, and Shock can be absorbed by deformation.
