[0001]
BACKGROUND OF THE INVENTION
The present invention relates to vehicle armrests installed in interior parts such as automobile door trims and rear corner trims that are mounted on a side wall panel of a vehicle, and particularly maintains a good feeling when an occupant puts an elbow on the armrest. The present invention relates to a vehicle armrest that can be used.
[0002]
[Prior art]
Normally, armrests are installed on automobile door trims, rear corner trims, and the like that are installed on the side walls of vehicles so that passengers can take a comfortable posture by putting their elbows on them.
[0003]
For example, FIG. 8 and FIG. 9 illustrate the configuration of an automobile door trim provided with an armrest. The door trim 1 is formed into a curved shape, and the resin core material 2 having a shape retaining property and a mounting rigidity with respect to the door panel. A surface material 3 excellent in touch and decoration is attached to the surface, and the center portion of the surface is formed as an armrest mounting portion 4 that bulges out indoors. An armrest 5 is attached to the armrest mounting portion 4. It is attached via attachment means such as a clip.
[0004]
The armrest 5 is composed of an armrest core 6 made of a synthetic resin injection-molded body and an armrest skin 7 attached to the surface of the armrest core 6. In order to ensure lightweight and excellent cushion performance, the armrest skin 7 is made of an injection-molded body of soft vinyl chloride, and has a plurality of spacer ribs 8 on the back surface. When an occupant applies an elbow to the armrest 5 and applies a load, the cushion ribs have excellent cushioning properties. To ensure.
[0005]
[Problems to be solved by the invention]
However, in the conventional armrest 5 for a vehicle, although the spacer rib 8 for ensuring the cushioning performance is provided on the back surface of the armrest skin 7, the occupant applies an elbow to the armrest 5 as shown in FIG. In particular, when this load is applied in the inclination direction, the spacer rib 8 falls in an inclined state, and the expected elastic repulsion cannot be obtained, giving the occupant a feeling of bottoming and lowering the cushion performance. Has been pointed out.
[0006]
The present invention has been made in view of such circumstances, and for vehicle armrests installed in door trims, rear corner trims, etc., when a passenger has an elbow on the armrest, the vehicle has good cushioning performance. The aim is to provide armrests.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides an armrest core made of a synthetic resin injection-molded body, and an armrest made of a soft resin attached to the surface of the armrest core and having spacer ribs of appropriate dimensions and length integrally formed on the back surface. A vehicle armrest that is composed of a skin and is mounted on the surface of the armrest installation part of interior parts such as door trims , and is positioned between the armrest skin and the armrest core when a vertical load is applied from the surface side of the armrest skin In the vehicle armrest that gives a soft feeling by elastically deforming the spacer rib in a substantially square shape, the armrest core surface has a spacer rib that regulates the collapse of the spacer rib when a vertical load is applied to the armrest It is characterized in that a fall-in restricting means is provided.
[0008]
Here, the interior parts can be applied to automobile door trims and rear corner trims mounted on a side wall panel of a vehicle.
[0009]
The armrest is composed of an armrest core made of a synthetic resin injection-molded body and an armrest skin attached to the surface of the armrest core. The armrest core is an injection-molded body of a synthetic resin such as polypropylene resin or ABS resin. On the other hand, the armrest skin is made of an injection-molded body of soft resin having excellent tactile sensation such as soft vinyl chloride, and a plurality of spacer ribs with appropriate lengths are formed on the back surface. In addition, as an attachment means of an armrest, it fixes to the armrest attachment part of interior parts using conventional fixing means, such as screw fixation fixation and clip fixation.
[0010]
When the armrest epidermis is attached to the armrest core surface, the spacer rib tip abuts against the armrest core surface, so that the clearance of the length of the mounted spacer rib is between the armrest core and the armrest epidermis. When the occupant puts his elbow on the surface of the armrest, the spacer rib bends in a square shape so that an elastic repulsion force acts at that time, and a good cushion performance is obtained.
[0011]
In addition, as a spacer rib fall-in restricting means provided on the surface of the armrest core, for example, a fitting recess to be fitted to the tip of the spacer rib formed on the armrest skin is formed on the surface of the armrest core corresponding to each spacer rib. In addition, in order to restrict the tip of the spacer rib from slipping over the surface of the armrest core, a stopper projection having a stopper function for hooking and locking the tip of the spacer rib may be provided.
[0012]
The stopper protrusion may be formed integrally with the armrest core, or a mesh sheet or the like may be separately attached to the armrest core surface separately from the armrest core.
[0013]
As is clear from the above configuration, if the spacer rib collapse regulation means is provided on the surface of the armrest core, when the occupant puts his elbow on the surface of the armrest, the spacer rib will not collapse. It can be elastically deformed in a substantially square shape, and the elastic repulsion force can be effectively secured.
[0014]
Furthermore, if a configuration is adopted in which a fitting recess that fits with the tip of the spacer rib is provided on the surface of the armrest core as a spacer rib fall-in restricting means, when attaching the armrest skin to the surface of the armrest core, it is easy and quick to align the two. It can be done.
[0015]
In addition, as a spacer rib collapse regulation means provided on the armrest core surface, if the spacer protrusion is formed at a position slightly shifted from the contact portion between the spacer rib and the armrest core, the occupant has an elbow on the armrest. At the time of the initial load, the spacer rib is slightly inclined and the spacer rib is locked to the stopper projection, and thereafter, the spacer rib does not stretch against the load, and is easily elastically deformed into a square shape.
[0016]
In addition, if a configuration in which a mesh sheet or the like is affixed to the surface of the armrest core as the spacer rib collapse regulation means provided on the surface of the armrest, the mold processing of the injection mold of the armrest core can be simplified.
[0017]

1 and 2, an automotive door trim 10 has an appropriate shape retaining property and attachment rigidity to a door inner panel, and has a resin core material 11 formed into a curved shape and affixed to the surface of the resin core material 11. It is generally composed of a skin material 12 that is worn and imparts cushioning properties and decorative properties.
[0020]
An approximately central portion of the surface of the door trim 10 is formed in a bulging shape on the vehicle interior side, and an armrest installation portion 13 having an upper surface set in a substantially flat shape is formed, and the present invention is formed on the upper surface of the armrest installation portion 13. The vehicle armrest 20 according to the above is installed.
[0021]
As shown in FIGS. 2 and 3, the vehicle armrest 20 is attached to the armrest core 30 made of a synthetic resin injection-molded body such as polypropylene resin or ABS resin, and the surface of the armrest core 30. The arm rest skin 40 is generally composed of a touch feeling, surface texture, and cushioning.
[0022]
The armrest core 30 has an embossed clip mounting seat 31 formed on the back surface, and the clip 32 mounted on the clip mounting seat 31 is press-fitted into the mounting hole 14 formed in the armrest installation portion 13 of the door trim 10. By combining, the armrest 20 is attached to a predetermined location of the door trim 10.
[0023]
In addition, in order to secure the cushioning property of the armrest 20, a plurality of spacer ribs 41 extending toward the armrest core 30 are formed on the back surface of the armrest skin 40, and the elastic repulsive force of the spacer rib 41 Good cushion performance is secured.
[0024]
By the way, the present invention provides a good cushion performance by effectively applying the elastic repulsion force of the spacer rib 41, and is characterized in that a means for restricting the fall of the spacer rib 41 is provided. That is, as shown in FIG. 3, a fitting recess 33 into which the tip 41 a of the spacer rib 41 is fitted is formed on the surface of the armrest core 30 corresponding to the spacer rib 41.
[0025]
Therefore, when the occupant puts his elbow on the upper surface of the armrest 20, as shown in FIG. 4, the tip 41 a of the spacer rib 41 formed on the armrest skin 40 is a fitting recess provided on the surface of the armrest core 30. Since the occupant puts his elbow on the surface of the armrest 20 and the load F is applied to the armrest 20, the spacer rib 41 does not fall down and is substantially in a letter shape as shown in the figure. The elastic repulsive force A acts at that time, and good cushion performance is obtained.
[0026]
In addition, in the embodiment in which the fitting recess 33 is formed in the armrest core 30 as the spacer rib collapse restriction means, when the armrest skin 40 is attached to the surface of the armrest core 30, the armrest is placed in the fitting recess 33 of the armrest core 30. An advantage that the armrest core 40 and the armrest skin 40 can be integrated easily and quickly by positioning the armrest skin 40 easily and quickly by fitting the tips 41a of the spacer ribs 41 of the skin 40. There is.
[0027]
Furthermore, by adjusting the recess depth of the fitting recess 33 formed in the armrest core 30, the armrest core 30 is easily broken with the fitting recess 33 as a base point, and when an impact is applied from the outside such as a side collision. There is also an attendant advantage that this impact load can be absorbed effectively.
[0028]
Next, FIG. 5 and FIG. 6 show the configuration and the operation of the second embodiment of the vehicle armrest 20 according to the present invention. As shown in FIG. A plurality of stopper protrusions 34 are formed on the surface of the armrest core 30.
[0029]
The stopper projection 34 only needs to be provided at a position surrounding the contact portion 35 between the tip 41a of the spacer rib 41 and the surface of the armrest core 30, and as shown in FIG. When the occupant puts his elbow on, the spacer rib 41 provided on the armrest skin 40 moves slightly so as to slide on the surface of the armrest core 30 with respect to the initial load F1, but the tip 41a of the spacer rib 41 is used as a stopper. The spacer rib 41 is restrained by engaging with the projection 34, and the subsequent load F2 is elastically deformed into a substantially square shape as shown in FIG. The force B acts to obtain good cushion performance.
[0030]
In particular, since the spacer rib 41 is slightly inclined, the spacer rib 41 is not stretched, and is smoothly elastically deformed, and an elastic repulsive force at that time can be obtained, so that the soft feeling can be more emphasized. .
[0031]
In the configuration in which the stopper protrusion 34 is formed on the armrest core 30, the workability is slightly inferior in the work of integrating the armrest core 30 and the armrest skin 40 as compared with the first embodiment, but for the stopper. The position accuracy of the protrusion 34 can be relatively rough and the stopper protrusion 34 can have a reinforcing rib function. Therefore, the thickness of the armrest core 30 can be reduced, and the weight can be reduced. There is a feature that the shock absorbing performance can be enhanced.
[0032]
In addition, as shown in FIG. 7, as a spacer rib fall-in regulating means, a mesh sheet 50 may be bonded and fixed to the surface of the armrest core 30, and when the elbow is attached to the upper surface of the armrest 20, the tip of the spacer rib 41 Since 41a is caught in the mesh of the mesh sheet 50 and can be prevented from falling down, the same effects as in the second embodiment can be obtained.
[0033]
Further, if a non-woven fabric sheet, cloth or the like is attached instead of the mesh sheet 50, the tips 41a of the spacer ribs 41 are restrained by the frictional resistance of the non-woven fabric sheet or cloth, and the same effect is expected. it can.
[0034]
In addition, when a mesh sheet 50, a nonwoven fabric sheet, or a woven fabric sheet is affixed to the surface of the armrest core 30, the molding process of the molding die can be easily performed compared to the structure in which the stopper protrusion 34 is formed on the armrest core 30, and the cost is low. There is an advantage that it can be implemented.
[0035]
Moreover, although embodiment mentioned above showed what installed the armrest 20 for vehicles in the door trim 10, it is also possible to apply to a rear corner trim.
[0036]
