Description

  The present invention relates to a vehicle armrest.

  Conventionally, the thing of the following patent document 1 is known as an armrest for vehicles. Specifically, an armrest provided with a skin material constituting the upper portion of the armrest, a base material constituting the lower portion of the armrest, and a cushion material disposed in a space formed between the skin material and the base material It is. A foam material such as urethane is used for the cushion material, and the cushion material is sealed with a base material and a skin material.

JP 2012-245824 A

  Urethane foam that is foam-molded and used as a cushioning material contains air and is sealed with the base material and skin material as described above, and the skin material with low air permeability is used. When heat is applied, the air in the urethane foam expands, and a situation may occur in which a part of the skin material swells or peels off. In order to avoid such problems, for example, countermeasures have been taken to provide holes for releasing air at locations where urethane foam is placed on the base material, but inevitably post-processing after foam molding of urethane As a result, the number of work processes increases and it is not efficient.

  Accordingly, there is a need for an armrest that allows the air in the urethane foam layer to escape by a relatively simple method and does not affect the design surface even when the air permeability of the base material or the skin material is low.

  This invention is completed based on the said situation, Comprising: It aims at providing the armrest for vehicles which is hard to produce the swelling and peeling in a skin material.

  In order to solve the above problem, a vehicle armrest according to the present invention is coated with a base material, a cushion material disposed on a part of the base material, and an adhesive agent on the base material and the cushion material. A skin material, wherein the base material has a vent hole in a portion where the cushion material is not disposed, and the skin material is a region where the cushion material is disposed at least from the air hole. A non-adhesive region where the adhesive is not disposed is provided so as to be bonded to the base material.

  According to such a vehicle armrest, although the cushioning material is covered with the skin material together with the base material, the skin material has an adhesive straddling the region where the cushioning material is disposed from the vent hole provided in the base material. Since the non-adhesive region that is not disposed is adhered to the base material, an air escape path is formed from the non-adhesive region to the vent hole, and air in the cushion material can be escaped from the vent hole. In particular, when materials with low air permeability are used for the base material or skin material, the effect of such air escape passages and ventilation holes is exhibited, so the material used for the base material and skin material has good air permeability. A wide range of options. In addition, by forming a vent hole in the base material where the cushion material is not disposed, it does not interfere with the foam molding of the cushion material. Excellent.

  The vehicle armrest is formed in a vehicle trim, and the base member includes an upper surface portion that bulges toward the vehicle interior side, and a vehicle interior that extends downward from a vehicle interior side end portion of the upper surface portion. A side surface portion, and the vehicle interior side surface portion includes a first surface portion that extends upward from the vehicle interior side end portion, and a second surface portion that extends further downward from a lower end of the first surface portion. The second surface portion is an inclined surface that is inclined toward the outside of the passenger compartment as it goes downward, and the cushion material is disposed from the upper surface portion to at least a part of the first surface portion, and the vent hole May be formed on the second surface portion.

  According to such a vehicle armrest, the cushioning material is arranged from the upper surface portion where the occupant's arm is placed or where the occupant's body is easy to contact to at least a part of the first surface portion of the side surface of the vehicle interior. Therefore, an appropriate cushioning property in the armrest is ensured. On the other hand, the second surface portion that is a lower portion of the side surface portion of the passenger compartment and that is inclined to the outside of the passenger compartment as it goes downward is a place where the arm or body of the occupant is relatively difficult to contact. The need for cushioning material is low. By forming a vent hole in the second surface portion where such a cushioning material is not disposed, air in the cushioning material can be released without impairing the cushioning properties of the armrest.

  In the vehicle armrest, the upper end of the non-adhesion region may be located in the vicinity of the vehicle interior side end. According to such a vehicle armrest, the upper end in the non-adhesion region (that is, the boundary between the region where the adhesive is applied and the region where the adhesive is not applied) is the boundary between the upper surface portion of the base material and the side surface portion of the vehicle interior. Since it is located in the vicinity of a certain vehicle interior side end, the influence on the design surface can be reduced. In other words, for example, if such a boundary is located on the upper surface part that is most easily visible to the occupant, the influence of the presence or absence of adhesive will be noticeable when it appears on the surface of the skin material, and the design of the armrest will be impaired. In a place where there is a change in the angle such as the end portion on the vehicle interior side, it is preferable that it is relatively inconspicuous.

  ADVANTAGE OF THE INVENTION According to this invention, the armrest for vehicles which can hardly produce the swelling and peeling in a skin material can be provided.

<Embodiment 1>
Hereinafter, Embodiment 1 of the present invention will be described with reference to FIGS. In each figure, F means the front of the vehicle, R means the rear of the vehicle, IN means the vehicle interior side direction, and OUT means the vehicle interior direction. As shown in FIG. 1, the vehicle door trim 1 is configured by assembling an upper board 20 that forms an upper part, a main board 30 that forms an intermediate part, a lower board 40 that forms a lower part, and the like. One plate is formed so as to extend in the longitudinal direction of the vehicle. In addition, in this embodiment, although what divides | segments into three board members, the upper board 20, the main board 30, and the lower board 40, and comprises the vehicle door trim 1, it does not restrict to this but is a single board member. It may be constituted by two board members or other four or more board members.

  The upper board 20 is provided with an inner handle 12 for releasing the door lock when the occupant opens the vehicle door from the vehicle interior side. The lower board 40 is provided with a door pocket 13 and a speaker grill 14. The vehicle door trim 1 includes an armrest 50 (corresponding to a “vehicle armrest” according to the present invention) that bulges toward the vehicle interior side, approximately in the center in the vehicle vertical direction and toward the rear of the vehicle. The armrest 50 extends substantially horizontally in the vehicle interior side direction and can be placed on the upper surface portion 51 on which the occupant's arm can be placed. And the vehicle interior side surface portion 52. A pull handle 11 having an upper opening is provided at the approximate center of the upper surface 51 of the armrest 50 in the vehicle front-rear direction so that a passenger can insert a hand when opening and closing the vehicle door from the vehicle interior side.

  The armrest 50 includes a base material 60 serving as a base, a cushion material 70, and a skin material 50C. The substrate 60 is made of a non-porous resin such as polypropylene (PP) resin. The base material 60 is a long member as shown in FIG. 2, and the base material upper surface portion 61 extends substantially horizontally so as to bulge in the vehicle interior side direction in a state of being provided in the vehicle door trim 1. And a base material vehicle interior side surface portion 62 that extends downward from the base material vehicle interior side end portion 61T in the base material upper surface portion 61. The base material vehicle interior side surface portion 62 is located above the base material vehicle interior side end portion 61T and extends from the lower end 63 of the base material first surface portion 621 further downward. And at least a surface portion 622.

  The boundary 620 between the base material first surface portion 621 and the base material second surface portion 622 is mainly located at the approximate center in the vehicle vertical direction in the base material vehicle interior side surface portion 62, and the upper half is the base material first surface portion 621. Although the lower half is the base material second surface portion 622, the area of the base material first surface portion 621 increases toward the rear end portion 60R, and the base material interior side surface portion 62 is closer to the rear of the vehicle. It is comprised only by the base material 1st surface part 621 (refer FIG. 2). That is, the boundary 620 line that runs substantially in the center in the vehicle vertical direction in the base vehicle interior side surface 62 in the substantially horizontal direction descends in front of the rear end 60R of the base 60. As shown in FIGS. 4 and 5, the base material first surface portion 621 is a substantially vertical surface facing the vehicle interior side, and the base material second surface portion 622 is an inclined surface that inclines toward the vehicle compartment outer side as it goes downward. ing. The inclination angle from the lower end 63 of the base material first surface portion 621 to the base material second surface portion 622 becomes gentler toward the rear of the vehicle (see FIGS. 2, 4, and 5).

  As shown in FIG. 2, a cushion material 70 is arranged from the base material upper surface portion 61 to the base material first surface portion 621 in the base material 60. The cushion material 70 is a porous resin, and is disposed on a part of the base material 60 by foaming a foam material such as urethane. The cushion material 70 is disposed so as to cover the front end 60 </ b> F of the base material 60. As described above, since the base vehicle interior side surface portion 62 is constituted only by the base material first surface portion 621 at the rear side of the vehicle, the cushion material 70 is disposed downward.

  As shown in FIG. 4, the outer end 65 of the base material upper surface 61 in the vehicle interior / exterior direction has a shape that rises upward. It is shaped to be folded back into the passenger compartment. Note that the lower end portion 66 of the base vehicle interior side surface portion 62 is shaped to bend toward the vehicle exterior side. Further, in the side surface portion 62 of the base material vehicle interior, the vicinity of the lower end 63 of the base material first surface portion 621 and the vicinity where the lower end 70D of the cushion material 70 is arranged is a stepped portion 621S (FIGS. 4 and 5). reference).

  Ventilation holes 80 (80A, 80B, 80C) are formed in the base material 60 so as to penetrate the vehicle interior and exterior direction at portions where the cushion material 70 is not disposed. The three air holes 80 (80A, 80B, 80C) are formed in the base material second surface portion 622 of the base material vehicle interior side surface portion 62 so as to be spaced apart from each other so as to be arranged in the vehicle front-rear direction. Since the penetration direction of the ventilation holes 80 (80A, 80B, 80C) is the same as the die-cutting direction of the base material 60, it can be provided at the same time as the base material 60 is molded, and the forming work efficiency is excellent. The number and positions of the air holes 80 depend on the shape of the armrest 50, the length in the longitudinal direction, the manner in which the cushion material 70 is disposed, and the like, provided that the base material 60 is provided at a location where the cushion material 70 is not disposed. It can be changed as appropriate.

  The skin material 50 </ b> C is disposed on the base material 60 and the cushion material 70 so as to be covered with the adhesive 90. The skin material 50C is made of a material having relatively low air permeability such as artificial leather such as polyurethane. As shown in FIGS. 4 and 5, the skin material 50 </ b> C covers the base material 60 (the base material upper surface portion 61 and the base material vehicle interior side surface portion 62) and the cushion material 70, while The cushion material 70 is arranged so as to cover the back surface 60B side of the side end portion 66, and the cushion material 70 is sealed with the base material 60 and the skin material 50C. Here, the skin material 50C has at least the adhesive 90 over the region where the cushion material 70 in the vicinity thereof is disposed from each of the vent holes 80 (80A, 80B, 80C) provided in the base material second surface portion 622. Non-adhered regions 88 (88A, 88B, 88C) that are not arranged are respectively provided and bonded (see FIG. 3-5). That is, each non-adhesive material layer 88 (88A, 88B, 88C) is provided across a part corresponding to a part of the base material first surface part 621 from a part of the base material second surface part 622, respectively.

  As described above, the vehicle armrest 50 according to the present embodiment includes the base material 60, the cushion material 70 disposed on a part of the base material 60, and the base material 60 and the cushion material 70 with the adhesive 90. The base material 60 has a ventilation hole 80 formed in a portion where the cushion material 70 is not disposed, and the skin material 50C has at least a ventilation hole 80 (80A, 80B, 80C) and the non-adhesive region 88 (88A, 88B, 88C) where the adhesive 90 is not disposed over the region where the cushion material 70 is disposed, and is bonded to the base material 60.

  For this reason, although the cushion material 70 is covered with the base material 60 by the skin material 50C, the skin material 50C is provided with the cushion material 70 from the vent holes 80 (80A, 80B, 80C) provided in the base material 60. Since the non-adhesive region 88 (88A, 88B, 88C) in which the adhesive 90 is not disposed across the region to be bonded is adhered to the base material 60, the air holes 80 are formed from the non-adhesive region 88 (88A, 88B, 88C). An air escape path is formed over (80A, 80B, 80C), and the air in the cushioning material 70 can escape from the vent hole 80 (80A, 80B, 80C). In particular, when a material having low air permeability is used for the base material 60 or the skin material 50C, such an air escape path and the effect of the air holes 80 (80A, 80B, 80C) are exhibited. The material used for the skin material 50 </ b> C is not limited to a material having good air permeability, and options are widened.

  Further, by forming the vent holes 80 (80A, 80B, 80C) in the portion of the base material 60 where the cushion material 70 is not disposed, it does not hinder the foaming of the cushion material 70. The pores 80 (80A, 80B, 80C) can be provided, and the working efficiency is excellent. Moreover, the usage fee can be reduced as much as the adhesive 90 is not partially applied. The configuration of the armrest 50 according to the present invention is effective not only when the air permeability of the skin material 50C is low but also when the stitch is not applied to the skin material 50C by design (if there is a stitch, the stitch seam From the air).

  The vehicle armrest 50 is formed in the vehicle trim 1, and the base material 60 includes a base material upper surface portion 61 that bulges toward the vehicle interior side, and a base material vehicle in the base material upper surface portion 61. A base material vehicle interior side surface portion 62 extending downward from the indoor side end portion 61T, and the base material vehicle interior side surface portion 62 is formed above the base material vehicle interior side end portion 61T. It is comprised at least from the 1st surface part 621 and the base material 2nd surface part 622 extended further downward from the lower end 63 in the base material 1st surface part 621, and the base material 2nd surface part 622 goes outside a vehicle interior as it goes below. The cushion material 70 is disposed from the base material upper surface part 61 to at least a part of the base material first surface part 621, and the vent holes 80 (80 </ b> A, 80 </ b> B, 80 </ b> C) are the base material second surface part 622. It is assumed that it is formed It is possible.

  According to such a vehicle armrest 50, the vehicle interior of the vehicle from the base material upper surface portion 61 (a location corresponding to the upper surface portion 51 of the armrest 50) where the passenger's arm is placed or the occupant's body is easily in contact. Since the cushion material 70 is arranged over at least a part of the base material first surface portion 621 of the side surface portion 62 (a portion corresponding to the upper side of the armrest 50 in the vehicle interior side surface portion 52), an appropriate cushioning property in the armrest 50 is ensured. Will be. On the other hand, a base material second surface portion 622 (a portion corresponding to a lower portion of the armrest 50 in the vehicle interior side surface portion 52) that is a lower portion of the base material vehicle interior side surface portion 62 and is inclined downward toward the vehicle interior as it goes downward. Since the occupant's arm or body is relatively difficult to contact, the necessity of placing the cushion material 70 in such a place is low. By forming the air holes 80 (80A, 80B, 80C) in the base material second surface portion 622 where the cushion material 70 is not arranged, the air in the cushion material 70 is not affected by the cushioning property of the armrest 50. It is possible to escape.

<Embodiment 2>
Next, a second embodiment of the present invention will be described with reference to FIGS. The configuration of the vehicle armrest 50 according to the first embodiment is partly changed, and the configuration common to the first embodiment is described using the same reference numerals, and is the same as the configuration of the first embodiment. The description of the operation and effect will be omitted.

  Each upper end 288U in each non-adhesion region 288 (288A, 288B, 288C (288C is not shown)) in the armrest 250 according to the present embodiment is a base vehicle interior side end 61T (a vehicle interior side end of the armrest 250) 51T (corresponding to 51T). That is, each non-adhesive material layer 288 (288A, 288B, 288C) is provided across a portion corresponding to the upper end 621U of the base material first surface portion 621 from a part of the base material second surface portion 622, respectively.

  According to such a vehicle armrest 250, the upper end 288U (that is, the boundary between the area where the adhesive is applied and the area where the adhesive is not applied) in the non-adhesive area 288 (288A, 288B, 288C) A base material vehicle interior side end 61T (armrest) that is a boundary between the base material upper surface portion 61 (corresponding to the upper surface portion 51 in the armrest 250) and the base material vehicle interior side surface portion 62 (corresponding to the vehicle interior side surface portion 52 in the armrest 250). Therefore, the influence on the design surface can be reduced. In other words, for example, when such a boundary is located on the base material upper surface portion 61 (upper surface portion 51) that is most likely to enter the occupant's field of view, the effect of the presence or absence of the adhesive 90 appears on the surface of the skin material 50C. Although it becomes conspicuous and impairs the design of the armrest 250, it is preferable that it is relatively inconspicuous in a place where there is a change in angle, such as the base vehicle interior side end 61T (vehicle interior side end 51T).
