Description

  The present invention relates to a vehicle door trim.

  Conventionally, a vehicle door trim is provided with an armrest having a shape projecting toward the vehicle interior side. Such an armrest is required to be easily crushed in the projecting direction at the time of a vehicle collision (mainly a side collision from the side surface). This is to reduce the impact received by the occupant by being easily crushed when the occupant collides with the armrest during a side collision. As an example of an armrest configured to be easily crushed at the time of a side collision, one described in Patent Document 1 below is known. In the armrest described in Patent Literature 1, the wall portion constituting the armrest is made of a beam material divided at a plurality of locations. In other words, by forming a plurality of notches in the wall portion of the armrest, the armrest is easily crushed during a side collision.

JP 2007-253738 A

  However, in order to reduce the impact of the occupant at the time of a side collision, an armrest having a structure that is more easily crushed in the projecting direction is required, and there is room for improvement in this respect.

  The present invention has been completed based on the above-described circumstances, and an object thereof is to provide a vehicle door trim including an armrest that can be easily crushed in an overhanging direction.

  In order to solve the above problems, a vehicle door trim according to the present invention is a vehicle door trim including a board member, and an armrest provided on the board member and projecting toward the vehicle interior side, The top plate of the armrest is configured by bridging a bridging member over an opening formed in the board member, and the bridging member has flexibility and is stretched in the protruding direction of the armrest. It is characterized by being attached to the board member.

  In the present invention, the top plate of the armrest is configured by bridging a flexible bridging member over an opening formed in the board member. As a result, the armrest can be easily crushed in the overhang direction to reduce the impact on the occupant during a side collision, compared to a configuration in which the top plate of the armrest is a member having no flexibility (high rigidity). Can do. Furthermore, the bridging member constituting the top plate of the armrest is attached to the board member in a state of being stretched in the armrest extending direction. Thereby, the bending of a bridge member at the time of putting an elbow etc. on a bridge member can be controlled. Moreover, since the bridging member has flexibility, stress concentration when placing an elbow or the like can be suppressed. As a result, it is possible to suppress a situation where the bridging member is damaged due to repeated loads. From the above points, in the armrest of the present invention, it is possible to suppress the stress concentration when placing the elbow on the armrest while the armrest is easily crushed at the time of a side collision, and the durability of the armrest is also good. Become.

  In the above configuration, the board member has a pair of bridging member mounting portions arranged so as to sandwich the opening in the projecting direction of the armrest, and each of the pair of bridging member mounting portions includes: Both ends of the bridging member in the projecting direction are respectively attached, and each of the both ends of the bridging member is on a surface opposite to the opening in each of the pair of bridging member attachments. It can be attached.

  When an elbow or the like is placed on the bridging member, both ends of the bridging member in the projecting direction of the armrest are pulled inward of the opening. In the present invention, each of the both ends of the bridging member is attached to a surface on the opposite side of the opening in each of the bridging member attachment portions. With such a configuration, when both ends are pulled inward of the opening, both ends are hooked on the corresponding bridging member mounting portions. Thereby, the situation where the both ends of a bridge member are pulled in the inner side of an opening can be controlled. For this reason, when an elbow or the like is placed on the bridging member from above, the bridging member can be made more difficult to bend and the elbow can be more reliably supported.

  Moreover, the said bridge | crosslinking member and the said board member shall be joined by welding. If it does in this way, it is not necessary to use joining means, such as an adhesive agent, for joining between a bridge member and a board member. Thereby, workability is improved and the cost for joining can be reduced.

  ADVANTAGE OF THE INVENTION According to this invention, the vehicle door trim provided with the armrest which can be crushed easily in the overhang | projection direction can be provided.

<Embodiment 1>
A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing a schematic configuration of a vehicle door trim 10 according to the present embodiment. FIG. 2 is a perspective view showing a state in which the vehicle door trim 10 is viewed from the rear surface side (the vehicle compartment outer side). As shown in FIG. 1, the vehicle door trim 10 includes a trim board 12 and an ornament 14 attached to the trim board 12. Further, the vehicle door trim 10 includes a door pocket 15 and a speaker grill 16. In addition, the right side of FIG. 1 is a vehicle front side, and the left side is a vehicle rear side.

  The trim board 12 (board member) is a member constituting a main body portion of the vehicle door trim 10 and is formed of a synthetic resin. The ornament 14 (board member) is attached so as to close the opening formed in the trim board 12. When the ornament 14 is attached to the trim board 12, the surface of the ornament 14 (the surface on the vehicle interior side), The surface of the trim board 12 (surface on the vehicle interior side) is substantially flush.

  In addition, the trim board 12 may be comprised with the integral component, and may be comprised with the some member. For example, the trim board 12 may be configured by two members arranged above and below. When the trim board 12 is composed of two members, the upper member is generally referred to as an upper board and the lower member is referred to as a lower board. Further, a skin material (not shown) is attached so as to cover the surface of the trim board 12 on the vehicle interior side.

  In the trim board 12, an armrest 20 that can be used as an armrest by an occupant is provided below the ornament 14. The armrest 20 is mainly formed by projecting a part of the trim board 12 toward the vehicle interior side. As shown in FIGS. 1 and 2, the armrest 20 includes a bracket 30 and a bridging member 50 attached to the bracket 30.

  As shown in FIG. 2, the bracket 30 is attached to the trim board 12 from the rear surface side (outside of the passenger compartment) so as to block the trim side opening 13 formed in the trim board 12. The bridging member 50 is attached to the trim board 12 via the bracket 30. That is, the bracket 30 constitutes a part of the armrest 20 and has a function for attaching the bridging member 50 to the trim board 12. By attaching the bracket 30 to the trim board 12 after the bridging member 50 is attached to the bracket 30, workability is improved as compared with the configuration in which the bridging member 50 is directly attached to the trim board 12. The trim side opening 13 is formed in the trim board 12 by notching a part of the side portion 20A of the armrest 20 and the top plate 20B.

  As shown in FIGS. 2 and 3, the bracket 30 has a shape extending in the vehicle front-rear direction as a whole. The bracket 30 extends in the horizontal direction and has a rectangular shape in plan view, an upper plate part 32 extending upward from the outer peripheral edge of the main body part 31, and a vehicle interior side periphery of the main body part 31. And a lower plate portion 33 extending downward from the end.

  The main body 31 has a bracket-side opening 31A (opening) formed so as to penetrate in the up-down direction. The bracket side opening 31 </ b> A has a rectangular shape and is formed to open substantially the entire surface of the main body 31. Further, as shown in FIG. 4, the upper plate portion 32 and the lower plate portion 33 are arranged so as to sandwich the bracket-side opening 31 </ b> A in the projecting direction of the armrest 20 (the left-right direction in FIG. 4).

  As shown in FIG. 4, the upper plate portion 32 is arranged along the plate surface direction of the ornament 14. As shown in FIG. 4, the lower plate portion 33 extends from the trim board 12, the front portion 34 arranged in a substantially flush manner, and the lower end of the front portion 34. 4, and a lower end portion 36 that extends from the lower end of the inclined portion 35 and extends in the plate surface direction of the trim board 12.

  As shown in FIG. 3, screw insertion holes 37 through which the screws B <b> 1 can be inserted are formed at a plurality of locations in the lower end portion 36 of the upper plate portion 32 and the lower plate portion 33. A plurality of screw insertion holes 37 are arranged in the vehicle front-rear direction (three in this embodiment). On the other hand, as shown in FIGS. 2 and 4, on the back side of the trim board 12 and the ornament 40, a mounting boss 38 having a substantially cylindrical shape is provided outside the passenger compartment (see FIG. In FIG. 4, it protrudes toward the right side).

  As shown in FIG. 4, the mounting boss 38 is formed with a screw mounting hole 38A into which the screw B1 can be screwed. As shown in FIG. 4, after each screw B1 is inserted into each screw insertion hole 37, the bracket 30 is attached to both the trim board 12 and the ornament 40 by screwing the tip of the screw B1 into the screw mounting hole 38A. It is attached.

  The bridging member 50 is flexible and has a sheet shape. The bridging member 50 only needs to be flexible, and examples thereof include a nonwoven fabric, a woven fabric, and a synthetic resin sheet material. In addition, it is preferable that the bridging member 50 has a characteristic that it is difficult to stretch against tension in the extending direction (particularly in the direction outside the vehicle interior). In FIG. 2, the bridging member 50 is hatched.

  As shown in FIG. 3, the bridging member 50 is affixed to the bracket 30 by an adhesive means (for example, an adhesive) in a state where the bridging member 50 is bent along the surface shape of the bracket 30. The bridging member 50 includes an upper end portion 51 that covers the upper plate portion 32 of the bracket 30, a central portion 52 that overlaps the main body portion 31 of the bracket 30, and a lower end portion 53 that covers the lower plate portion 33 of the bracket 30. ing.

  As shown in FIG. 4, the central portion 52 of the bridging member 50 is arranged so as to cover the bracket-side opening 31 </ b> A. Further, the upper end portion 51 of the bridging member 50 is attached to the surface 32 </ b> A on the outer side of the passenger compartment of the upper plate portion 32. And the front-end | tip part of the upper end part 51 is turned up by the upper end side of the upper board part 32, and is affixed on the surface 32B of the upper board part 32 at the vehicle interior side. In other words, the upper end portion 51 is wound around the upper plate portion 32, and the situation where the upper end portion 51 is peeled off from the upper plate portion 32 can be more reliably suppressed. As shown in FIG. 3, a cut portion 56 is formed in the central portion 52 of the bridging member 50 and a boundary portion between the central portion 52 and the upper end portion 51. This cut portion 56 is for facilitating the work of attaching the upper end portion 51 to the surface 32A of the upper plate portion 32 outside the passenger compartment.

  Further, the lower end portion 53 of the bridging member 50 is attached to a surface 33B of the lower plate portion 33 on the vehicle interior side. The front end portion of the lower end portion 53 is folded back at the lower end side of the lower plate portion 32 and is attached to a surface 33A of the lower plate portion 33 on the outer side of the passenger compartment. In other words, the lower end portion 53 is wound around the lower plate portion 33. In addition, in the upper end part 51 and the lower end part 53 of the bridging member 50, a screw insertion hole 54 into which the screw B1 can be inserted is formed at a place overlapping the screw insertion hole 37.

  In other words, the bridging member 50 has the upper plate portion 32 and the lower plate portion 33 (a pair of bridging members) in the bracket 30 at both end portions (upper end portion 51 and lower end portion 53) in the extending direction of the armrest 20 (left and right direction in FIG. 4). It is attached to the attachment part). Each of the upper end portion 51 and the lower end portion 53 of the bridging member 50 is attached to a surface of the upper plate portion 32 and the lower plate portion 33 opposite to the bracket side opening portion 31A.

  Further, side end portions 55 extending from the central portion 52 of the bridging member 50 to both sides in the vehicle front-rear direction are attached to both side wall portions 39 of the bracket 30 in the vehicle front-rear direction, respectively. The bridging member 50 is attached to the bracket 30 in a state of being stretched in the extending direction (particularly, the extending direction of the armrest 20).

  From the above configuration, when the bracket 30 is attached to the trim board 12, the bridging member 50 is bridged over the bracket side opening 31A (and thus the trim side opening 13). In other words, the top plate of the armrest 20 is configured by spanning the bridging member 50 over the bracket side opening 31A (and thus the trim side opening 13).

  As described above, the vehicle door trim 10 of the present embodiment is a vehicle door trim 10 that includes the trim board 12 and the armrest 20 that is provided on the trim board 12 and has a shape projecting toward the vehicle interior side. The top plate of the armrest 20 is configured by bridging the bridging member 50 over the bracket side opening 31A formed in the bracket 30, and the bridging member 50 has flexibility, It is attached to the bracket 30 (and thus the trim board 12) in a stretched state.

  In the present embodiment, the top plate of the armrest 20 is configured by bridging a flexible bridging member 50 to a bracket side opening 31 </ b> A formed in the bracket 30. Thereby, compared with the structure whose top plate of the armrest 20 is a highly rigid member, the armrest 20 is easily crushed at the time of a side collision, and the impact on the occupant can be reduced.

  The effects described above will be specifically described with reference to FIGS. FIG. 5 is a graph showing the results of a load test in which the side portion 20A of the armrest 20 is pressed from the vehicle interior side direction with a load meter. The horizontal axis in FIG. 5 indicates the displacement (mm) of the pressed portion pressed by the load meter to the outside of the vehicle, and the vertical axis indicates the load (KN) measured by the load meter. Note that the load measured by the load meter corresponds to a reaction force when the load meter displaces the pressed portion, and the higher the load, the harder the armrest 20 is crushed during a side collision. That is, the load indicated by the vertical axis is proportional to the magnitude of impact when the human body collides with the armrest 20, and is preferably as low as possible.

  Moreover, the graph (a) in FIG. 5 shows a measurement result obtained by performing a load test on a configuration in which the bracket 30 of the present embodiment is attached to the armrest 20. Moreover, the graph (b) in FIG. 5 shows the measurement result which performed the load test about the structure which attached the bracket 1 of the comparative example instead of the bracket 30 of this embodiment.

  FIG. 6 is a perspective view showing a bracket 1 of a comparative example. In the bracket 1, the same parts as those of the bracket 30 are denoted by the same reference numerals. A plurality of slits 1 </ b> A extending in the vehicle front-rear direction are arranged in the main body 2 of the bracket 1. A plurality of slits 1A are arranged in the vehicle front-rear direction, and two rows of slits 1A are arranged in the vehicle interior / exterior direction.

  The measurement results shown in the graph of FIG. 6 will be described. First, in the bracket 1, the load increases as the displacement of the pressed portion increases (the pressed portion is crushed). As described above, the bracket 1 is formed with two rows of slits 1 </ b> A in the vehicle interior and exterior direction. For this reason, the formation location of the slit 1A is easily crushed, and the load is temporarily reduced in the process of crushed the armrest. In the graph (b), the two places where the load is temporarily reduced are shown because the slits 1A are formed in two rows in the vehicle interior / exterior direction.

  On the other hand, also in the bracket 30, the load increases as the displacement of the pressed portion increases. However, in the bracket 30 of the present embodiment, almost the entire surface of the main body 31 is the bracket side opening 31A. For this reason, compared with the case of the bracket 1, the load is reduced about 50% on average. From the above results, according to the configuration of the present embodiment, it was confirmed that the armrest 20 was more easily crushed than the comparative example, and the impact received by the occupant from the armrest 20 during a side collision could be confirmed.

  Furthermore, in the present embodiment, the bridging member 50 constituting the top plate of the armrest 20 is attached to the bracket 30 in a state of being stretched in the projecting direction of the armrest 20. Thereby, the bending (especially vertical deflection) of the bridging member 50 when the elbow or the like is placed on the bridging member 50 can be suppressed, and the elbow or the like can be more reliably supported.

  Moreover, since the bridging member 50 has flexibility, stress concentration when placing an elbow or the like can be suppressed. As a result, it is possible to suppress a situation where the bridging member 50 is damaged or whitened due to repeated loads. From the above points, in the armrest 20 of the present embodiment, the armrest 20 can be easily crushed at the time of a side collision, and stress concentration when an elbow or the like is placed on the armrest 20 can be suppressed. The property is also good.

  It should be noted that a test was performed in which a constant load was repeatedly applied from above on the top plate of the armrest 20 of the present embodiment (more precisely, the central portion 52 of the bridging member 50) and the durability was measured at that time. However, the armrest 20 of this embodiment can confirm that the number of endurances has increased by about 15 times or more compared to a configuration in which the top plate of the armrest is made of a synthetic resin member (for example, the same material as the trim board 12). It was.

  Further, in the present embodiment, the bracket 30 includes an upper plate portion 32 and a lower plate portion 33 (a pair of bridging member attachment portions) arranged so as to sandwich the bracket side opening portion 31A in the projecting direction of the armrest 20. The upper plate portion 32 and the lower plate portion 33 are respectively attached with both end portions (upper end portion 51 and lower end portion 53) in the extending direction of the bridging member 50, and both end portions of the bridging member 50 are respectively The upper plate portion 32 and the lower plate portion 33 are respectively attached to surfaces on the opposite side to the bracket side opening portion 31A.

  When an elbow or the like is placed on the central portion 52 of the bridging member 50, both ends of the bridging member 50 in the projecting direction of the armrest 20 are pulled inwardly of the bracket side opening 31A. In the present embodiment, both end portions of the bridging member 50 are respectively attached to the surfaces of the upper plate portion 32 and the lower plate portion 33 opposite to the bracket side opening portion 31A.

  With such a configuration, when the upper end 51 and the lower end 53 are pulled inward of the bracket side opening 31A, the upper end 51 and the lower end 53 are respectively the upper plate 32 and the lower plate 33. Will be caught. In FIG. 4, when an elbow or the like is placed on the bridging member 50 (center portion 52), a reference numeral A <b> 1 is attached to a portion where the upper end portion 51 of the upper plate portion 32 is hooked, and a lower end portion 53 of the lower plate portion 33. A2 is attached to the place where the

  Thereby, the situation where the upper end part 51 and the lower end part 53 of the bridging member 50 are pulled in the inner side direction of the bracket side opening 31A can be suppressed. For this reason, when an elbow or the like is placed on the bridging member 50 from above, the bridging member 50 can be made more difficult to bend and the elbow or the like can be more reliably supported.

<Embodiment 2>
Next, a second embodiment of the present invention will be described with reference to FIGS. In the vehicle door trim 110 of the present embodiment, the configuration of the bridging member 150 attached to the bracket 30 is different from that of the above embodiment. Note that the same portions as those in the above embodiment are denoted by the same reference numerals and redundant description is omitted.

  In the first embodiment, the upper end portion 51 of the bridging member 150 is mainly attached to the surface 32A of the upper plate portion 32 outside the passenger compartment. In contrast, in the present embodiment, as shown in FIGS. 7 to 9, the upper end portion 51 of the bridging member 150 is mainly attached to the surface 32 </ b> B on the vehicle interior side of the upper plate portion 32. In other words, in the present embodiment, a large portion of the bridging member 150 (a portion excluding the peripheral end portion folded back to the vehicle interior side) is attached to a surface (one surface) of the bracket 30 on the vehicle interior side. Thereby, the operation | work which affixes the bridge | crosslinking member 150 on the bracket 30 becomes easy compared with the structure of the said Embodiment 1. FIG.

  In addition, since most of the bridging member 150 (a portion excluding a part of the peripheral end portion) is pasted on the surface of the bracket 30 on the vehicle interior side, the bridging member 50 is pasted simultaneously with the molding of the bracket 30. It can also be attached. Next, with reference to FIG.10 and FIG.11, the shaping | molding method which affixes the bridge | crosslinking member 150 simultaneously with shaping | molding of the bracket 30 is demonstrated.

  10 and 11 are cross-sectional views showing a mold 160 (upper mold 170 and lower mold 180) for molding the bracket 30. FIG. In the present embodiment, the lower mold 180 is, for example, a fixed mold, and the upper mold 170 is, for example, a movable mold. The upper mold 170 is movable in the vertical direction (movable relative to the lower mold 180) by moving means such as a hydraulic cylinder (not shown), for example. Thereby, the mold 160 can be closed or opened. 10 and 11 corresponds to the projecting direction of the armrest 20.

  The upper mold 170 and the lower mold 180 are opposed to each other and have stepped molding surfaces. When the molding die 160 is closed (the state shown in FIG. 11), the bracket 30 is interposed between both molding surfaces. A cavity 161 (molding space) corresponding to the shape is formed. An injection device (resin supply unit, not shown) is connected to the cavity 161 via a nozzle (not shown) so that a molten synthetic resin can be supplied into the cavity 161.

  In FIG. 11, cavities for forming the upper plate portion 32 and the lower plate portion 33 of the bracket 30 are illustrated. In FIG. 11, of the cavities 161, cavities for forming the upper plate portion 32 are denoted by reference numeral 162, and cavities for forming the lower plate portion 33 are denoted by reference numeral 163.

  A part of the mold for forming the cavity 163 is a slide mold 171 that can slide (movable in the left-right direction in FIG. 11) relative to the upper mold 170. Thereby, it is possible to die-cut the lower plate portion 33 having an undercut portion after molding.

  Further, of the surface of the upper mold 170 facing the lower mold 180, a plurality of protrusions 172 projecting toward the lower mold 180 are formed at the peripheral end. On the other hand, the lower mold 180 is formed with an insertion hole 182 into which the protrusion 172 can be inserted when the mold is closed.

  Next, a procedure for forming the bracket 30 using the mold 160 will be described. First, the bridging member 150 is attached to the upper mold 170 in a state where the mold 160 is opened (a state where the upper mold 170 and the lower mold 180 are separated). Specifically, the peripheral end portion of the bridging member 150 is passed through each projecting portion 172 and is held by the upper mold 170.

  With the bridging member 150 held by the upper mold 170, the upper mold 170 is moved toward the lower mold 180, and the mold 160 is closed. As a result, a cavity 161 is formed between the upper mold 170 and the lower mold 180. Simultaneously with the mold closing, the bridging member 150 is pressed against the molding surface of the lower mold 180. As a result, the bridging member 150 has a shape corresponding to the surface of the bracket 30 on the vehicle interior side. Further, the bridging member 150 is held by the upper mold 170 so as to penetrate the protruding portion 172, and the displacement in the extending direction of the bridging member 150 is restricted to some extent. For this reason, the bridging member 150 is in a state of being stretched in the extending direction of the bridging member 150 (particularly the left-right direction in FIG. 11 which is the extending direction of the armrest 20) by being pressed against the molding surface of the lower mold 180.

  Next, the synthetic resin material in a melted state is supplied into the cavity 161, and the bracket 30 is formed by solidifying the synthetic resin material. In this molding process, a molten synthetic resin material enters between the fibers of the bridging member 150. And since the synthetic resin material is solidified, the bridging member 150 and the bracket 30 are firmly joined. Thereby, simultaneously with shaping | molding of the bracket 30, it can affix on the bracket 30 in the state which stretched | crosslinked the bridging member 150 in the extending direction (welding). In addition, after removing the bracket 30 from the shaping | molding die 160, the excess part in the bridge | crosslinking member 150 is cut | disconnected.

  As described above, in the present embodiment, the bridging member 150 is mainly attached to the surface (one side) of the bracket 30 on the vehicle interior side. If it does in this way, it will also become possible to join bracket 30 and bridge member 150 by welding simultaneously with fabrication of bracket 30. For this reason, it is not necessary to use joining means such as an adhesive for joining the bridging member 150 and the bracket 30. Thereby, workability is improved and the cost for joining can be reduced.

  In addition, the shaping | molding method which affixes a bridge | crosslinking member simultaneously with shaping | molding of the bracket illustrated in this embodiment is applicable even if the sticking object of a bridge | crosslinking member is members other than a bracket. For example, in the case of a configuration in which the bridging member 150 is directly affixed to the trim board 12, the bridging member 150 can be affixed to the trim board 12 simultaneously with the molding of the trim board 12.

<Embodiment 3>
Next, Embodiment 3 of the present invention will be described with reference to FIG. The same parts as those in each of the above embodiments are given the same reference numerals and redundant description is omitted. In the vehicle door trim 210 of the present embodiment, the configurations of the bracket 230 and the bridging member 250 are different from those of the above embodiments.

  In the present embodiment, the trim board 212 is formed with a fitting portion 212A into which the lower plate portion 233 of the bracket 230 can be fitted. The lower plate portion 233 is provided with a mounting pin 238 that protrudes outward from the passenger compartment.
