Description

The present invention relates to a vehicle armrest that is attached to a vehicle door and protrudes toward the interior of the vehicle.

Vehicle armrests that are provided on vehicle doors are known (see, for example, Patent Document 1). Such vehicle armrests are compressed by a side airbag that deploys when a collision occurs against the side of the vehicle (hereinafter, referred to as a side impact).

The vehicle armrest in Patent Document 1 is formed to protrude toward the inside of the vehicle cabin from the door trim that is fixed to the interior side of the vehicle door. The vehicle armrest in Patent Document 1 also has an upper surface, and three grooves that reduce strength are formed on the back side of the upper surface. The vehicle armrest in Patent Document 1 is pressed by the side airbag, and these grooves are crushed. When the grooves are crushed in this way, the vehicle armrest deforms, and a space is created between the seated occupant and the armrest.

JP 2007-83899 A

In the vehicle armrest of Patent Document 1, the three grooves are formed in a curved shape with the center bulging outward toward the outside of the vehicle compartment so that when the side airbag deploys, the distance from the area pressed by the side airbag is approximately uniform. However, when the vehicle crashes sideways, the door deforms, so the area pressed by the side airbag is not necessarily constant. For this reason, in the vehicle armrest of Patent Document 1, the grooves do not collapse, and there is a risk that the vehicle armrest will not deform.

Vehicle armrests also have the function of supporting the arms of a passenger. For this reason, vehicle armrests need to be rigid enough to prevent the upper surface of the vehicle armrest from bending even when a passenger places their arm on it.

The objective of the present invention is to provide a vehicle armrest that can promote deformation in the event of a side collision while suppressing a decrease in rigidity.

The vehicle armrest according to the present invention is provided on a vehicle door and protrudes toward the interior of the vehicle. The vehicle armrest includes a base portion, a first through hole, and a recess. The base portion has a first surface capable of supporting the arm of a vehicle occupant, and a second surface formed on the opposite side to the first surface, and serves as the base material of the vehicle armrest. A plurality of first through holes are provided in the base portion, extend in the front-rear direction of the vehicle, and penetrate from the first surface to the second surface. The recess is provided at a position adjacent to the first through hole in the front-rear direction of the vehicle, and is cut out from at least one of the first surface or the second surface toward the other surface.

According to this vehicle armrest, for example, when the vehicle armrest is pressed in the vehicle width direction by a side airbag that deploys when the vehicle crashes sideways, the first through hole promotes deformation of the vehicle armrest so that it narrows in the vehicle width direction. When the deformation of the vehicle armrest is promoted by the first through hole, pressure acts on the recess adjacent to the first through hole, and the pressure shears the vicinity of the recess. As a result, deformation of the vehicle armrest is promoted. On the other hand, the recess has a higher rigidity than the first through hole, and by providing a recess adjacent to the first through hole, a decrease in rigidity of the vehicle armrest can be suppressed. This makes it possible to prevent the first surface from bending when the first surface supports the arm of an occupant. In other words, this configuration makes it possible to provide a vehicle armrest that can promote deformation in the event of a vehicle crash while suppressing a decrease in rigidity.

The recess may have a sloping portion. The sloping portion may be sloping from the deepest portion of the recess toward the starting point where the notch is formed in the surface in which the recess is provided.

With this configuration, when the deformation of the vehicle armrest is accelerated, the applied pressure causes the vicinity of the recess to be sheared. When the vicinity of the recess is sheared, one end of the sheared portion rides up onto the inclined portion. When the one end rides up onto the inclined portion, it is guided toward the surface on which the recess is provided. As a result, the deformation of the vehicle armrest to narrow in the vehicle width direction is carried out more smoothly.

The recess may include a first recess and a second recess. The first recess may have a first inclined portion. The second recess may have a second inclined portion. The first inclined portion may be inclined from a first deepest portion, which is the deepest position of the first recess, toward a starting point where the cutout of one first surface is formed. The second inclined portion may be inclined from a second deepest portion, which is the deepest position of the second recess, toward a starting point where the cutout of the other second surface is formed.

According to this configuration, one end of the sheared portion near the recess rides up on the first inclined portion or the second inclined portion. In addition, the other end of the sheared portion near the recess contacts the inclined portion of the first inclined portion or the second inclined portion that is different from the inclined portion on which the one end rides up. As a result, both the one end and the other end of the sheared portion near the recess are guided by the first inclined portion and the second inclined portion. In addition, the first inclined portion and the second inclined portion are formed in one direction. As a result, both the first inclined portion and the second inclined portion can be smoothly guided without getting caught. As a result, the deformation of the vehicle armrest narrowing in the vehicle width direction is performed more smoothly.

The first recess may have a first wall portion. The second recess may have a second wall portion. The first wall portion may extend from the first deepest portion in a direction different from the first inclined portion. The second wall portion may extend from the second deepest portion in a direction different from the second inclined portion. The first wall portion and the second wall portion may be provided on a straight line in a cross-sectional view in the vehicle width direction. The first deepest portion may be provided closer to the first surface than the second deepest portion. The second deepest portion may be provided closer to the second surface than the first deepest portion.

According to this configuration, for example, when the vehicle armrest is pressed in the vehicle width direction by a side airbag that deploys when the vehicle is side-collisioned, the pressure is transmitted through the first wall portion and the first inclined portion and concentrated in the first deepest portion. Similarly, the pressure is transmitted through the second wall portion and the second inclined portion and concentrated in the second deepest portion. In addition, since the first deepest portion is closer to the first surface side than the second deepest portion, and the second deepest portion is closer to the second surface side than the first deepest portion, the area between the first deepest portion and the second deepest portion is thinner than other portions. The pressure concentrated in the first deepest portion and the second deepest portion acts in a direction that shears the thin-walled recessed portion. At this time, the first wall portion and the second wall portion are arranged in a straight line in a cross-sectional view in the vehicle width direction, so the shearing distance is short. As a result, the recessed portion is easily sheared. On the other hand, when the vehicle armrest is not pressed in the vehicle width direction, the portion between the first deepest portion and the second deepest portion that is thinner than the other portions can further suppress the decrease in rigidity of the vehicle armrest.

A door trim may be provided on the interior side of the door. The vehicle armrest may further include a boss portion provided on the base portion for attaching the base portion to the door trim. The boss portion may be provided at a position that overlaps with the first through hole in the vehicle width direction when viewed from above on the first surface.

This configuration allows the force from the boss to be easily transmitted to the first through hole, which further promotes deformation in the vehicle width direction.

Either the first through hole or the recess may pass through the center line of the upper surface in the vehicle width direction.

According to this configuration, either the first through hole or the recess passes through the center line of the upper surface in the vehicle width direction. The center line is approximately midway between the position where pressure is applied from the side airbag and the position where pressure is applied from the door trim. Therefore, either the first through hole or the recess receives pressure from both the inside and outside of the vehicle compartment at the same time. This further promotes deformation of the armrest.

The vehicle armrest may further include a second through hole. The second through hole may be provided in the base portion, extend in the vehicle width direction, and penetrate from the first surface to the second surface. The second through hole may be provided between the first through hole and the recess.

With this configuration, the second through-hole is crushed in the vehicle width direction, making it easier for pressure to be transmitted to the first through-hole and the recess.

The present invention provides a vehicle armrest that can promote deformation in the event of a side collision while suppressing a decrease in rigidity.

First Embodiment
A first embodiment of the present invention will be described below with reference to the drawings. In the following description, the front-rear direction of a vehicle C is indicated as Q in the drawings, and the front side is indicated as F. The left-right direction of the vehicle C (an example of the vehicle width direction) is indicated as P in the drawings, and the right side as viewed from the rear of the vehicle C is indicated as R. Furthermore, the up-down direction of the vehicle C is indicated as G in the drawings, and the upper side is indicated as U.

As shown in FIG. 1, the vehicle armrest 1 is provided on the door 4 of a vehicle C equipped with a side airbag 8, and supports the arm of an occupant seated in a seat 6 on the door 4 side. In this embodiment, the vehicle armrest 1 provided on the front left door 4 of the vehicle C is described as an example, but the vehicle armrest 1 may be provided on each door of the vehicle C.

When a sensor (not shown) detects a side collision of the vehicle C, the side airbag 8 deploys between the occupant seated in the seat 6 and the door 4 to reduce the impact received from the side by the occupant of the vehicle C. In this embodiment, the side airbag 8 is provided on the door 4 side of the seat 6. As shown in FIG. 3, when the side airbag 8 deploys, the vehicle armrest 1 and the side airbag 8 come into contact with each other.

As shown in Figures 1 and 2, a door trim 2 is provided on the interior side of the door 4, which is fixed to an inner panel (not shown) of the door 4. The door trim 2 has a protruding portion 2a that protrudes into the interior side of the vehicle C. As shown in Figure 2, the protruding portion 2a is provided with an operation panel opening 2b and an attachment opening 2c to which a vehicle armrest 1 is attached. An operation panel (not shown) is attached to the operation panel opening 2b, which is provided with switches for operating the power windows of the vehicle C.

As shown in FIG. 2, the vehicle armrest 1 is provided so as to be attachable to the mounting opening 2c of the door trim 2, and is provided so as to protrude toward the interior of the vehicle cabin by covering the mounting opening 2c. At least the surface of the vehicle armrest 1 that supports the occupant's arm is provided with a skin 22 made of a urethane material with a decorative material such as cloth or leather attached. The skin 22 is decorated to match the interior decoration of the vehicle cabin, such as the seat 6, and by attaching the vehicle armrest 1 to the mounting opening 2c, the skin 22 can be matched with the interior decoration of the vehicle cabin without changing the door trim 2. In this embodiment, at least the skin 22 of the vehicle armrest 1 protrudes toward the interior of the vehicle C beyond the protruding portion 2a, preventing the occupant's arm from contacting the protruding portion 2a.

Figure 3 is a cross-sectional view of the door trim 2 cut in the vehicle width direction P near where the vehicle armrest 1 is attached (see IV-IV in Figure 2). Furthermore, the upper part (a) of Figure 4 is a cross-sectional view of the vehicle armrest 1 of Figure 3 cut in the vehicle width direction P at part V-V. As shown in Figures 2, 3, and 4, the vehicle armrest 1 includes a base portion 10, a first through-hole 12, a second through-hole 14, a recess 16, a boss portion 18, and a thin-walled portion 20.

As shown in FIG. 2, the base portion 10 is a member that serves as the base material of the vehicle armrest 1. In this embodiment, the base portion 10 is formed by injection molding a synthetic resin material such as polypropylene. The base portion 10 has a support portion 10a (see FIG. 4) that extends toward the seat 6 in a cross-sectional view and supports the arm of an occupant, and a side wall portion 10b that bends downward from the tip of the support portion 10a. As shown in FIG. 4, the support portion 10a of the base portion 10 has an upper surface (an example of a first surface) 24 that can support the arm of an occupant of the vehicle C, and a lower surface (an example of a second surface) 26 formed on the opposite side of the upper surface 24 in the vertical direction G. A skin 22 is adhered to at least the upper surface 24 of the base portion 10.

2, the first through holes 12 are provided in the support portion 10a of the base portion 10, extend in the fore-and-aft direction Q of the vehicle C, and penetrate from the upper surface 24 to the lower surface 26. In this embodiment, three first through holes 12 are provided side by side in the fore-and-aft direction Q of the base portion 10. However, it is sufficient that one or more first through holes 12 are provided in the base portion 10. As shown in FIG. 3, the first through holes 12 extend in the fore-and-aft direction Q along a center line X1 whose longitudinal direction passes near the center of the upper surface 24 of the base portion 10. The length of the first through holes 12 in the vehicle width direction P is shorter than the length of the recess 16 in the vehicle width direction P.

2, the second through hole 14 is provided in the support portion 10a of the base portion 10, extends in the vehicle width direction P of the vehicle C, and penetrates the support portion 10a from the upper surface 24 to the lower surface 26. The second through hole 14 is provided between the first through hole 12 and the recess 16. In this embodiment, as shown in FIG. 3, the second through hole 14 is provided in two rows in the vehicle width direction P across the center line X1, and these two second through holes 14 are provided in two rows in the front-rear direction Q, for a total of four. However, it is sufficient that one or more second through holes 14 are provided in the base portion 10. The second through hole 14 has a longitudinal direction extending along the vehicle width direction P. The length of the second through hole 14 in the vehicle width direction P is longer than the length of the recess 16 in the vehicle width direction P. 3, the end 14a of the second through hole 14 on the door trim 2 side is located closer to the door trim 2 in the vehicle width direction P than the end 12a of the first through hole 12 on the door trim 2 side and the end 16c of the recess 16 on the door trim 2 side (see the dashed line in FIG. 3). Similarly, the end 14a of the second through hole 14 on the interior side of the vehicle is located closer to the interior side of the vehicle in the vehicle width direction P than the end 12a of the first through hole 12 on the interior side and the end 16c of the recess 16 on the interior side.

2, the recess 16 is provided at a position adjacent to the first through hole 12 of the support portion 10a in the front-rear direction Q of the vehicle C. In this embodiment, as shown in an enlarged view in FIG. 3, the recess 16 extends in the front-rear direction Q of the vehicle C along the center line X1 and is provided on both the upper surface 24 and the lower surface 26. That is, as shown in the upper part (a) of FIG. 4, the recess 16 includes a first recess 16a provided on the upper surface 24 and a second recess 16b provided on the lower surface 26. However, the recess 16 may be provided on at least one or both of the upper surface 24 and the lower surface 26. The recess 16 becomes deeper from the upper surface 24 or the lower surface 26 toward the other surface. In this embodiment, the first recess 16a becomes deeper toward the lower surface 26 as it approaches the door trim 2 side in the vehicle width direction P. The second recess 16b becomes deeper toward the upper surface 24 as it approaches the interior side of the vehicle in the vehicle width direction P.

As shown enlarged in FIG. 4(a), the recess 16 has an inclined portion 28. In this embodiment, the first recess 16a has a first inclined portion 28a, and the second recess 16b has a second inclined portion 28b. The inclined portion 28 is inclined from the deepest portion 30, which is the deepest position of the recess 16, toward the end 16c (an example of a starting point) where the notch of the upper surface 24 and the lower surface 26 where the recess 16 is provided is formed. In this embodiment, the first inclined portion 28a is inclined from the first deepest portion 30a, which is the deepest position of the first recess 16a, toward the upper surface 24 where the first recess 16a is provided, to the end 16c located on the inside of the cabin in the vehicle width direction P. That is, the first recess 16a is cut from the upper surface 24 toward the lower surface 26. The end 16c located on the inside of the cabin in the vehicle width direction P of the recess 16 is the starting point where the first recess 16a, which is the notch of the upper surface 24, is formed. The second inclined portion 28b slopes from the second deepest portion 30b, which is the deepest position of the second recess 16b, toward the lower surface 26 on which the second recess 16b is provided, to the end portion 16c on the door trim 2 side. That is, the second recess 16b is cut out from the lower surface 26 toward the upper surface 24. The end portion 16c of the recess 16 on the door trim 2 side in the vehicle width direction P is the starting point where the second recess 16b, which is the cutout of the lower surface 26, is formed.

That is, the first recess 16a has a slope that becomes deeper toward the door trim 2 side in the vehicle width direction P, and the second recess 16b has a slope that becomes deeper toward the inside of the vehicle compartment in the vehicle width direction P. Furthermore, in this embodiment, the angle α1 between the first inclined portion 28a connecting the first deepest portion 30a and the end 16c of the recess 16 on the interior side of the vehicle compartment and the upper surface 24 is equal to the angle α2 between the second inclined portion 28b connecting the second deepest portion 30b and the end 16c of the recess 16 on the door trim 2 side and the lower surface 26. That is, the first inclined portion 28a and the second inclined portion 28b are formed in the same direction and form parallel surfaces.

The first recess 16a has a first wall portion 32a. The second recess 16b has a second wall portion 32b. The first wall portion 32a extends from the first deepest portion 30a in a direction different from the first inclined portion 28a. In this embodiment, the first wall portion 32a extends from the first deepest portion 30a so as to be perpendicular to the upper surface 24. In other words, the first recess 16a has the shape of a right triangle, with the angle between the first wall portion 32a and the upper surface 24 being a right angle.

On the other hand, the second wall portion 32b extends from the second deepest portion 30b in a direction different from that of the second inclined portion 28b. In this embodiment, the second wall portion 32b extends from the second deepest portion 30b so as to be perpendicular to the lower surface 26. In other words, the second recess 16b has a right-angled triangular shape in which the angle between the second wall portion 32b and the lower surface 26 is a right angle.

In this embodiment, the first deepest portion 30a is provided closer to the upper surface 24 than the second deepest portion 30b. The second deepest portion 30b is provided closer to the lower surface 26 than the first deepest portion 30a. The depth S1 from the upper surface 24 to the first deepest portion 30a is the same as the depth S2 from the lower surface 26 to the second deepest portion 30b, and the first wall portion 32a and the second wall portion 32b are provided on a vertical line X2 (an example of a straight line) between the upper surface 24 and the lower surface 26. In other words, the shape of the second recess 16b is the same as the shape of the first recess 16a, which is point-symmetric with respect to the midpoint between the upper surface 24 and the lower surface 26 on the vertical line X2.

As shown in FIG. 3, the boss portion 18 is provided to attach the base portion 10 to the door trim 2. More specifically, the door trim 2 is provided with an insertion hole (not shown) through which the boss portion 18 can be inserted, and the base portion 10 is fixed and attached to the door trim 2 by inserting the boss portion 18 into this insertion hole and fixing it. As shown in the enlarged view of FIG. 3, the boss portion 18 is provided at a position overlapping the first through hole 12 in the vehicle width direction P when viewed from above on the upper surface 24.

As shown in FIG. 4, the thin-walled portion 20 is formed between the upper surface 24 or the lower surface 26 and the surface opposite to the surface on which the recess 16 is provided. In this embodiment, the thin-walled portion 20 is formed between the first recess 16a and the lower surface 26, and between the second recess 16b and the upper surface 24. The thin-walled portion 20 is a region thinner than the thickness of the meat portion 34 forming the support portion 10a sandwiched between the upper surface 24 and the lower surface 26, and is a region between the end 16c on the door trim 2 side and the end 16c on the interior side of the vehicle of the recess 16. In this embodiment, the first wall portion 32a and the second wall portion 32b are provided on the vertical line X2 (an example of a straight line) of the upper surface 24 and the lower surface 26, so that the thickness of the thin-walled portion 20 between the first deepest portion 30a and the second deepest portion 30b is the thinnest.

3, when a side collision occurs in the vehicle C, the vehicle armrest 1 configured in this manner is subjected to a pressure toward the inside of the vehicle compartment caused by the deformation of the door 4 toward the inside of the vehicle compartment. The vehicle armrest 1 is also subjected to a pressure toward the door trim 2 side caused by the deployment of the side airbag 8. That is, the vehicle armrest 1 is pressed in the vehicle width direction P from both the door trim 2 side and the inside of the vehicle compartment. At this time, the boss portion 18 is pressed from the door trim 2 and presses the first through hole 12 provided at a position overlapping the vehicle width direction P in a top view of the upper surface 24. The first through hole 12 is also pressed from the side airbag 8. The first through hole 12 passes through the center line X1, which is approximately the center between the position where the pressure from the side airbag 8 is applied and the position where the pressure from the door trim 2 acts. For this reason, the first through hole 12 is simultaneously subjected to pressure from the inside of the vehicle compartment and pressure from the door trim 2 side (outside of the vehicle compartment), and deformation that narrows in the vehicle width direction P occurs. Similarly, the second through hole 14 also deforms and narrows in the vehicle width direction P.

When the first through hole 12 and the second through hole 14 are deformed in such a way that they narrow in the vehicle width direction P, pressure acts on the recess 16. That is, as shown in the upper part (a) of FIG. 4, the pressure is transmitted through the first wall portion 32a and the first inclined portion 28a and concentrated on the first deepest portion 30a. Similarly, the pressure is transmitted through the second wall portion 32b and the second inclined portion 28b and concentrated on the second deepest portion 30b. The pressure concentrated on the first deepest portion 30a and the second deepest portion 30b acts in a direction that shears between the first deepest portion 30a and the second deepest portion 30b, which are the thinnest portions of the thin-walled portion 20. Since the first wall portion 32a and the second wall portion 32b are provided on the vertical line X2 in a cross-sectional view in the vehicle width direction P, the shearing distance is short and the thin-walled portion 20 is easily sheared.

When the thin-walled portion 20 is sheared, as shown in the lower part (b) of FIG. 4, one end 40 of the sheared portion rides on the first inclined portion 28a. Meanwhile, the other end 42 of the sheared portion is in contact with the second inclined portion 28b. In this state, both the one end 40 and the other end 42 are guided toward the end 16c by the first inclined portion 28a and the second inclined portion 28b. In this embodiment, the first inclined portion 28a and the second inclined portion 28b are formed in the same direction, so that the one end 40 and the other end 42 can be smoothly guided toward the end 16c without being caught by both the first inclined portion 28a and the second inclined portion 28b. As a result, the vehicle armrest 1 can promote deformation in which the vehicle armrest 1 narrows in the vehicle width direction P when the vehicle C crashes sideways.

On the other hand, when the vehicle armrest 1 is not pressed in the vehicle width direction P, the thin-walled portion 20 between the first deepest portion 30a and the second deepest portion 30b can suppress a decrease in the rigidity of the vehicle armrest 1. This allows the vehicle armrest 1 to suppress deflection of the upper surface 24.

As described above, the first embodiment of the present invention provides a vehicle armrest 1 that can promote deformation when the vehicle C is involved in a side collision while suppressing a decrease in rigidity.

Second Embodiment
Next, a second embodiment of the present invention will be described with reference to Fig. 5. In the following description, only the differences from the vehicle armrest 1 of the first embodiment will be described.

In the vehicle armrest 201 of the second embodiment, as shown in the upper part (a) of FIG. 5, the first inclined portion 228a inclines from the first deepest portion 230a, which is the deepest position of the first recess 216a, toward the upper surface 224 on which the first recess 216a is provided, to an end portion 216c (an example of a starting point in the second embodiment) on the door trim 2 side in the vehicle width direction P. That is, the first recess 216a is cut out from the upper surface 224 toward the lower surface 226. The end portion 216c on the door trim 2 side in the vehicle width direction P of the recess 216 is the starting point where the first recess 216a, which is a cutout in the upper surface 224, is formed. As shown in an enlarged view in the upper part (a) of FIG. 5, the second inclined portion 228b slopes from the second deepest portion 230b, which is the deepest position of the second recess 216b, toward the lower surface 226 on which the second recess 216b is provided, to an end portion 216c (an example of a starting point in the second embodiment) located on the inside of the vehicle compartment. That is, the second recess 216b is cut out from the lower surface 226 toward the upper surface 224. The end portion 216c of the recess 216 located on the inside of the vehicle compartment in the vehicle width direction P is the starting point where the second recess 216b, which is a cutout in the lower surface 226, is formed.

That is, the first recess 216a has a slope that becomes deeper toward the inside of the vehicle compartment in the vehicle width direction P, and the second recess 216b has a slope that becomes deeper toward the door trim 2 side in the vehicle width direction P.

In the vehicle armrest 201 configured in this manner, when the vehicle C is hit in a side collision and the thin-walled portion 220 is sheared, one end 240 of the sheared portion comes into contact with the second inclined portion 228b, as shown in the lower part (b) of FIG. 5. Meanwhile, the other end 242 of the sheared portion rides up onto the first inclined portion 228a. As a result, when the vehicle armrest 201 is deformed, the other end 242 moves toward the door trim 2. Therefore, the other end 242 does not protrude toward the passengers in the vehicle cabin. As a result, while deformation can be promoted when the vehicle C is hit in a side collision, the generation of protrusions due to deformation of the vehicle armrest 201 can also be suppressed.

As described above, the second embodiment of the present invention provides a vehicle armrest 201 that can promote deformation in the event of a side collision of vehicle C while suppressing a decrease in rigidity, while also suppressing the generation of protrusions due to deformation.

<Other embodiments>
Although two embodiments of the present invention have been described above, the present invention is not limited to the above-mentioned embodiments, and various modifications are possible without departing from the gist of the invention. In particular, the multiple modifications described in this specification can be arbitrarily combined as necessary.

(a) In the above first and second embodiments, the recesses 16, 216 are provided on both the upper surface 24, 224 and the lower surface 26, 226, but the present invention is not limited to this. The recesses 16, 216 may be provided by cutting out either the upper surface 24, 224 or the lower surface 26, 226.

(b) In the above first embodiment, an example was described in which the angle α1 between the first inclined portion 28a and the upper surface 24 and the angle α2 between the second inclined portion 28b and the lower surface 26 are the same, but the present invention is not limited to this. As long as the first inclined portion 28a and the second inclined portion 28b are formed facing in one direction, the angle α1 and the angle α2 may be different angles.

(c) In the above first embodiment, the vehicle armrest 1 is described using an example in which the door trim 2 and the base portion 10 are fixed via the boss portion 18, but the present invention is not limited to this. The vehicle armrest 1 may be molded integrally with the door trim 2.
