Abstract

PROBLEM TO BE SOLVED: To strongly fix an armrest by preventing looseness in engagement state without using a separate member, with reduction in cost promoted.SOLUTION: While both reinforcement ribs 3c of an engagement body 3 abut with an inside surface on a cabin side of a main hole part of an engagement hole 5, a claw member 3b of the engagement body 3 abuts with a side trim TR on the periphery of a central part of the engagement hole 5, for engagement. Thus, since both reinforcing ribs 3c abut with the inside surface of the engagement hole 5, elasticity of the claw member 3b is utilized to fully exhibit engagement holding force of the engagement body 3. Without using a separate member such as clip as before, looseness in engagement state is prevented so that an armrest 1 is strongly fixed to the side trim TR, for reducing a cost.

Description

  The present invention relates to a vehicle armrest mounting structure for mounting an armrest body to a surface of a side trim (including a deck side trim and a door trim) by locking engagement between a locking body and a locking hole.

  Conventionally, when mounting an armrest on a door trim mounted on the door inner side of a vehicle, a locking claw is formed on the armrest, and a locking claw on the armrest side is locked and fitted into a locking hole formed on the door trim side. The armrest is fixed to the door trim (see Patent Document 1).

JP-A-11-245703 (see paragraphs 0013 to 0014 and FIG. 1)

  However, in the mounting structure described in the above-mentioned patent document, a locking claw is integrally formed on the back surface of the horizontal elbow rest portion on the upper surface of the armrest, and the horizontal door trim mounting surface facing the elbow rest portion is engaged. Although the stop hole is formed, the shape of the armrest differs depending on the vehicle type, and as shown in FIGS.

  In the case of the armrest 50 having such a shape, for example, as shown in FIG. 10, a plurality of locking claws 50b are integrally formed downward on the back surface of the outer end portion of the armrest 50a made of resin. As shown in FIG. 11, the locking holes 60 are formed at positions facing the locking bodies 50b of the door trim TR, and the claws 50c are formed on the side surfaces of the locking bodies 50b on the vehicle interior side. The pair of reinforcing ribs 50d in the vertical direction are formed on the side surfaces of the respective locking bodies 50b on the outer side of the passenger compartment, the respective locking bodies 50b are inserted into the locking holes 60, and the claws 50c are locked and fitted, whereby the armrest 50 is mounted. Install.

  At this time, the resin armrest 50 is processed by resin molding, and each locking body 50b is also molded at the same time. However, as shown in FIGS. 9 and 10, the claw 50c of the locking body 50b is on the vehicle interior side. Both reinforcing ribs 50d are formed facing the outside of the passenger compartment, and by inserting the locking body 50b into the locking hole 60 of the door trim TR, the claw 50c is locked and fitted as shown in FIG. Mounted on door trim.

  However, in the mounting structure of the armrest 50 having the shape shown in FIGS. 7 to 11, as shown in FIG. 9, the claw 50c faces the vehicle interior side and the reinforcing rib 50d faces the vehicle interior outside, as shown in FIG. In order to mold the armrest 50 in this way, the mold cannot be slid out in the direction shown by the arrow in FIG. 9, and eventually the armrest 50 must be divided and combined later, There is a possibility of causing an increase in manufacturing cost due to division molding.

  On the other hand, when the armrest 50 is molded, a claw 51a is formed on the locking body 51 so as to protrude outward from the vehicle interior as shown in FIG. As shown in FIG. 6B, it is conceivable that only one reinforcing rib 51b is formed on the locking body 51 so as to protrude outward from the vehicle compartment. However, since the reinforcing rib 51b is one, the elasticity of the claw 51a is considered. Cannot be fully utilized, the locking force of the locking body 51 locked and fitted in the locking hole 60 on the door trim side becomes weak, and the armrest 50 cannot be firmly fixed to the door trim TR. There is a problem that rattling is likely to occur when the armrest 50 is attached, and a separate member such as a clip must be newly prepared and the attachment state must be reinforced by this separate member.

  An object of the present invention is to prevent rattling in a locked state without using a separate member, so that an armrest can be firmly fixed, and cost can be reduced. Another object of the present invention is to reduce the cost by forming the armrest so that it can be molded without being divided.

  In order to achieve the above-described object, a vehicle armrest mounting structure according to the present invention is a vehicle armrest mounting structure in which an armrest body is mounted on a side trim surface by locking engagement between a locking body and a locking hole. The locking body is erected in the same direction as the erection direction of the claw piece on both sides of the pedestal part, the elastic claw piece erected on the pedestal part, and the claw piece of the pedestal part. A pair of ribs, wherein the locking hole has a concave shape, and the ribs of the locking body abut against the inner surface of the locking hole, It is characterized by locking at the center of the locking hole (claim 1).

  Further, according to the present invention, the armrest main body has a cross-sectional shape, the pedestal portion of the locking body is formed on the surface side of the side trim, and the claw pieces and the ribs are the side The claw piece of the locking body may be disposed so as to stand on the surface side of the trim so as to move downward and engage with the locking hole.

  According to the first aspect of the present invention, since both the ribs of the locking body are in contact with the inner side surface of the locking hole, the claw pieces of the locking body are locked to the central portion of the locking hole. By making contact with the inner surface of the locking hole, it becomes possible to make full use of the elasticity of the claw piece to fully display the locking holding force of the locking body, and to prevent rattling in a locked state without using a separate member. Thus, the armrest can be firmly fixed to the side trim, and the cost can be reduced.

  According to the invention of claim 2, the base portion of the locking body is formed on the surface side of the side trim, and the claw pieces and both ribs are erected on the surface side of the side trim, Since the claw pieces are arranged so as to move downward and engage and engage with the engagement holes, the mold can be slid even with an armrest having a cross-sectionally W-shaped cross section. In this way, it is possible to mold the armrest without splitting the armrest so that the cost can be reduced compared to the case of manufacturing the split armrest and the dividing line by the mold remaining on the molded armrest The number of can be reduced as much as possible to improve the appearance.

The other conventional example is shown, (a) is a cut side view, (b) a partial plan view.

  Next, an embodiment of a vehicle armrest mounting structure according to the present invention will be described in detail with reference to FIGS. The following is an example applied to the right door.

  An automobile door is configured by combining a metal door outer panel, a metal door inner panel, and a resin door trim. A window glass is formed on a window formed by combining the door outer panel and the door inner panel. Is arranged so as to be movable up and down. A resin armrest 1 as shown in FIG. 1 is attached to a side trim such as a deck side trim or a door trim, and an elbow rest portion 1a on the upper surface thereof and a lower side from the vehicle interior side end portion of the elbow rest portion 1a. The armrest 1 is formed by resin molding, and the occupant's elbow can be placed on the elbow rest portion 1a. Are arranged as follows.

  The armrest 1 is attached to a side trim such as a deck side trim or a door trim by the following mounting structure. That is, as shown in FIG. 2, a plurality of locking bodies 3 (two in FIG. 2) are provided to hang downward at the outer end of the passenger compartment on the back surface of the armrest 1 a of the armrest 1. As shown in FIG. 5, these locking bodies 3 are locked and fitted into locking holes 5 formed in the side trim TR. Further, as shown in FIG. 2, engaging bosses 7 having claws at a plurality of tips extending toward the outside of the passenger compartment are planted at the lower end portion of the hanging portion 1b of the armrest 1. 7 is engaged with the engagement hole of the side trim TR to improve the mounting strength of the armrest 1.

  By the way, as shown in FIG. 3 and FIG. 4, the locking body 3 formed on the armrest 1 is provided with a base portion 3 a and an elastic member provided with a claw that is erected on the base portion 3 a and protrudes outward from the vehicle compartment at the upper end. And a pair of ribs 3c erected in the same direction as the erection direction of the claw piece 3b with the claw piece 3b sandwiched between the pedestal portion 3a and the upper ends of these ribs 3c are It is connected to the outer end of the passenger compartment on the back surface of the elbow rest 1a, and the locking body 3 is molded simultaneously with resin molding of the armrest.

  Further, a locking hole 5 is formed at each position of the side trim TR facing each locking body 3, and each locking hole 5 is located on the vehicle interior side in a plan view as seen from above as shown in FIG. A main hole 5a having a concave shape and a notch 5b formed by cutting the center of the main hole 5a further toward the vehicle interior side.

  When the locking body 3 is inserted into the locking hole 5, the end surfaces of the ribs 3 c of the locking body on the vehicle interior side are the inner side surfaces of the main hole portion 5 a of the locking hole 5 on the vehicle interior side. The claw at the tip end of the claw piece 5b comes into sliding contact with the side trim TR at the periphery of the central portion of the main hole portion 5a that is recessed toward the vehicle interior side, and the ribs 3c of the locking body 3 are locked. Is in contact with the inner surface of the engagement hole 5 on the vehicle interior side, the claw piece 3 b of the engagement body 3 is engaged, and the engagement body 3 is engaged with and engaged with the engagement hole 5.

  At this time, as shown in FIG. 5, the claw width L1 at the tip of the claw piece 3b of the locking body 3 does not exceed the width L2 of both ribs 3c, and the width L2 of both ribs 3c is the main hole portion of the locking hole 5. The width 3 is set to be slightly smaller than the width L3 of 5a. When the locking body 3 is locked and fitted into the locking hole 5, both ribs 3c of the locking body 3 are locked to the locking hole 5 as described above. Therefore, it is possible to make full use of the elasticity of the claw piece 3b to fully exert the locking holding force of the locking body 3.

  When the armrest 1 is molded with resin, for example, it can be molded by a combination of three molds indicated by A, B, and C in FIG. 3, and each of the molds A, B, and C is indicated by an arrow in FIG. By sliding or moving in the direction, all the molds A, B, and C can be extracted from the armrest 1 in which the locking body 3 is simultaneously molded. Therefore, unlike the conventional case, the armrest itself does not need to be divided, the manufacturing cost can be reduced, and the number of dividing lines by the mold remaining on the processed armrest 1 can be reduced to the minimum.

  Therefore, according to the above-described embodiment, the both reinforcing ribs 3c of the locking body 3 are in contact with the inner side surface of the main hole portion 5a of the locking hole 5 on the vehicle interior side, and the claw pieces 3b of the locking body 3 are Since both the reinforcing ribs 3c come into contact with the inner side surface of the locking hole 5 by making contact with the side trim TR at the peripheral edge of the central portion of the locking hole 5, the locking body 3 is utilized by utilizing the elasticity of the claw piece 3b. It is possible to sufficiently exert the locking holding force, and to prevent the rattling in the locked state without using a separate member such as a clip as in the prior art, and to firmly fix the armrest 1 to the side trim TR. In addition, the cost can be reduced.

  In addition, the base 3a of the locking body 3 is formed on the surface side of the side trim TR, which is the outer side of the armrest 1, and the claw pieces 3b and the reinforcing ribs 3c are also the outer side of the armrest 1. Since the claw piece 3b of the locking body 3 is arranged so as to move downward and engage with the locking hole 5 by being erected on the surface side of the side trim TR, the cross section has a W-shaped cross section. Even with the armrest 1, the molds A, B, and C can be slid as described above, and the armrest 1 can be molded without dividing the armrest as in the prior art. The cost can be reduced as compared with the case of manufacturing the armrest, and the appearance can be improved by reducing the number of dividing lines by the molds remaining in the molded armrest 1 as much as possible.

  The present invention is not limited to the above-described embodiment, and various modifications other than those described above can be made without departing from the spirit of the present invention.

  In the above-described embodiment, the armrest 1 having a cross-sectional shape in the cross section is taken as an example, but the armrest to which the present invention is applicable is not limited to this.

  Further, in the above-described embodiment, the case where the locking hole 5 includes the concave main hole portion 5a and the notch portion 5b at the center thereof has been described, but the present invention is similarly applied even without the notch portion 5b. Can be implemented.
