Description

Technical Field

[0001] The technology described in the specification of this application relates to interior trim parts for passenger vehicles. Background Art

[0002] As an example of interior trim parts for passenger vehicles, a door trim installed on the inner side of a vehicle door in the passenger compartment is cited. In the door trim, there is a structure in which a low-conductivity sheet is installed on the inner surface of a groove member. The purpose is to remove static electricity carried by passengers of the passenger vehicle. If a passenger inserts a hand into the inside of the groove member and contacts the low-conductivity sheet member, the static electricity carried by the passenger slowly moves to the low-conductivity sheet member and discharges by moving to the door inner panel via a high-conductivity sheet member and a bracket electrically connected to the door inner panel. Such interior trim parts for passenger vehicles are described in Patent Document 1 below, for example.

[0006] Problems to be Solved by the Invention

[0007] When releasing static electricity from the groove member to the door inner panel, the above-mentioned door trim passes through multiple members. That is, in addition to the components constituting the groove member, components such as a low-conductivity sheet and a high-conductivity sheet member are required, and there is a problem that the number of components increases and the manufacturing man-hours increase compared with the structure of the existing door trim.

[0008] The technology described in the specification of this application has been completed in view of such actual situations, and its purpose is to provide interior trim parts for passenger vehicles that can remove static electricity carried by passengers with a simple structure without increasing the number of components and manufacturing man-hours.

[0009] Solutions for Solving the Problems

[0010] The interior trim for a passenger vehicle is installed on the inner side of the passenger vehicle interior surface of a metal passenger vehicle body panel that constitutes the passenger vehicle body. It is characterized in that the interior trim for the passenger vehicle includes: an interior trim main body, which is plate-shaped as a whole; and an assembly member, which is assembled to the interior trim main body and has a contact surface for a passenger's hand to touch. The assembly member has: a base material, which has a main body portion for a passenger to hold and a mounting portion that extends from the main body portion and is used for mounting on the passenger vehicle body panel; and a conductive portion, which is formed of a conductive elastomer and is laminated on the base material. The conductive layer has a contact surface portion that forms the contact surface, at least one contact protrusion that protrudes from the base material toward the passenger vehicle body panel, and a connecting portion that connects the contact surface portion and the contact protrusion. When the interior trim for the passenger vehicle is installed on the passenger vehicle body panel, the protruding end of the contact protrusion contacts the inner side surface of the passenger vehicle interior of the passenger vehicle body panel in an elastically deformed state.

[0011] The protruding end of the contact protrusion has a plurality of contact pieces, and the plurality of contact pieces are configured to contact the passenger vehicle body panel in a state of independently elastically deforming.

[0012] The protruding end of the contact protrusion can be configured to be deformable in the in-vehicle and out-of-vehicle direction, and is configured to contact the passenger vehicle body panel in a flattened state. The protruding end of the contact protrusion can be made into a bag shape or a cylindrical shape. According to the interior trim for the passenger vehicle with this structure, it can be easily deformed in the in-vehicle and out-of-vehicle direction, so it can avoid the situation of separating from the side panel of the passenger vehicle body, and more reliably avoid the situation of the protruding part separating from the passenger vehicle body panel.

[0013] It can be set to the following structure: the mounting portion has a fixing portion for fixing to the passenger vehicle body panel, and the contact protrusion is disposed adjacent to the fixing portion.

[0014] It can be set to the following structure: the at least one contact protrusion is set to two contact protrusions, and the contact protrusions are disposed at positions opposite to each other with respect to the fixing portion.

[0015] In addition, in the interior trim for the passenger vehicle with this structure, the two contact protrusions and the fixing portion are not limited to a positional relationship of being arranged in a straight line. That is to say, the fixing portion may not be located on the straight line connecting the two contact protrusions.

[0016] It can be set to the following structure: the interior trim main body has a decorative panel for mounting on a vehicle door panel, and the assembly member has a handle member.

[0017] It can be configured as follows: the contact projection projects further toward the outside of the passenger vehicle with respect to the end on the outside of the passenger vehicle of the fixed portion.

[0018] It can be configured as follows: the mounting portion has a fixing portion for fixing to the passenger vehicle main body panel and a projection provided adjacent to the fixing portion, the projection projects toward the outside of the passenger vehicle from the surface on the outside of the passenger vehicle of the mounting portion, and at least one contact projection is provided at the protruding end of the projection.

[0019] It can be configured as follows: the connecting portion of the conductive layer has a portion formed on the surface of a portion between the end edge near the contact surface portion and the base end of the projection and a portion formed on the surface of a portion from the base end of the projection to the base end of the contact projection.

[0020] It can be configured as follows: the mounting portion has a fixing portion for fixing to the passenger vehicle main body panel and a first projection and a second projection provided adjacent to the fixing portion, the first projection and the second projection project toward the outside of the passenger vehicle from the surface on the outside of the passenger vehicle of the mounting portion, the first projection and the second projection are provided at positions opposite to each other with respect to the fixing portion, and at least one contact projection has a first contact projection and a second contact projection, the first contact projection is provided at the protruding end of the first projection, and the second contact projection is provided at the protruding end of the second projection.

[0021] It can be configured as follows: the connecting portion of the conductive layer has a portion formed on the surface of a portion between the end edge near the contact surface portion and the base ends of the first projection and the second projection, a portion formed on the surface of a portion from the base end of the first projection to the base end of the first contact projection, and a portion formed on the surface of a portion from the base end of the second projection to the base end of the second contact projection.

[0037] Refer to Figures 1 to 10 , the door trim 10 (interior trim for a passenger vehicle) of the technology described in the specification of the present application will be described. As Figure 1 And Figure 2 Shown, the door trim 10 is a component of the vehicle door 11 and is installed on the surface (inner side surface of the passenger compartment) of the vehicle body panel 12 (main body panel of the passenger vehicle) on the inner side of the passenger compartment (inner side of the passenger vehicle).

[0038] The vehicle body panel 12 includes an outer door panel 13 and an inner door panel 14, both of which are in the shape of a plate. The outer door panel 13 and the inner door panel 14 (door panels for passenger vehicles) are formed by stamping metal plates such as iron and aluminum, and coatings are applied to the outer surface of the outer door panel 13 on the outside of the vehicle body and the inner side surface 14A of the inner door panel 14 on the inside of the vehicle body. Various components such as a lifting mechanism for lifting the window glass 15 and a locking mechanism for locking the vehicle door 11 are arranged between the inner door panel 14 and the outer door panel 13.

[0039] As Figure 2 shown, the door trim 10 includes a decorative panel 20 (main body of the interior trim), an armrest 21, an inner handle 22, a pull handle 23, a speaker grille 24, and a door groove 25. The decorative panel 20 is in the shape of a plate as a whole. The armrest 21 is formed to bulge toward the inside of the vehicle body from the decorative panel 20. The speaker grille 24 covers the speaker 24A. The door trim 10 is constituted by assembling a plurality of plate members including the decorative panel 20. The decorative panel 20 is formed of a synthetic resin material (such as polypropylene) having electrical insulation properties and serves as a base for mounting other plate members.

[0040] The armrest 21 has an elbow rest surface 21A on which a passenger can place their arm. An armrest opening 21B that opens upward is formed in the front portion of the elbow rest surface 21A. A pull handle box 30 is assembled in the armrest opening 21B, and the pull handle 23 is formed.

[0041] As Figure 3 shown, the pull handle box 30 includes a pull handle member 31 (assembly member) and a cover member 32. The cross-section of the pull handle member 31 is substantially L-shaped and opens upward and outward. The cover member 32 is box-shaped and is arranged to block the outer opening of the pull handle member 31 and opens upward. As Figure 4 and Figure 5 shown, the pull handle member 31 has a main body portion 33 and a mounting piece 34 (mounting portion). The main body portion 33 is box-shaped and functions as a gripping portion of the pull handle 23. The mounting piece 34 is formed to extend outward from the outer edge of the main body portion 33 on the outside of the vehicle body.

[0042] The main body portion 33 has a lower wall portion 33A, side wall portions 33B, a front wall portion 33C, and a rear wall portion 33D. The inner surfaces of the side wall portions 33B, the front wall portion 33C, and the rear wall portion 33D are surfaces that come into contact with a passenger's hand when the passenger uses the pull handle 23. The lower wall portion 33A has a first fixing portion 36. A through hole 39 is provided in the first fixing portion 36. As Figure 3 shown, the first connecting member 38 passes through the through hole 39, and the first fixing portion 36 and the cover member 32 are fixed to the bracket 41 together. The bracket 41 is L-shaped and is fixed to the inner door panel 14 by a second connecting member 40 described later.

[0043] As Figure 4As shown, the mounting piece 34 has four through holes 35. When assembling the handle member 31 to the decorative panel 20, the connecting member is passed through the through holes 35. The number of through holes 35 is not limited to four. The mounting piece 34 also has a second fixing portion 37 for fixing to the inner door panel 14. The second fixing portion 37 is formed in a portion (front protruding portion) 34A of the mounting piece 34 that protrudes toward the vehicle front side. As Figure 6 shown, the second fixing portion 37 is formed in an inclined shape with the upper side inclined toward the outside of the vehicle compartment, and has a through hole 37A through which the connecting member passes. The connecting member is inserted into the through hole 37A and the connecting hole 42 formed in the inner door panel 14, and the second fixing portion 37 is fixed to the inner door panel 14.

[0044] The handle member 31 is a member formed by laminating and molding a conductive layer 51 on a base material 50. The base material 50 is formed of a synthetic resin material (non-conductive resin material such as polypropylene) having electrical insulation properties. The conductive layer 51 is formed of a conductive elastomer. The conductive layer 51 is shown shaded in Figures 4 to 6 the figure.

[0045] The base material 50 is molded into the shape of the handle member 31 described above. The base material 50 also has a first protrusion 50A and a second protrusion 50B. The first protrusion 50A and the second protrusion 50B are provided at positions adjacent to the second fixing portion 37 of the portion of the mounting piece 34 that constitutes the front protruding portion 34A.

[0046] The conductive layer 51 has a contact surface portion 52, a first contact protrusion 53, a second contact protrusion 54, and a connecting portion 55. The contact surface portion 52 covers the entire part of the inner surface of the base material 50 that constitutes the side wall portion 33B, the front wall portion 33C, and the rear wall portion 33D described above. The first contact protrusion 53 is formed so as to protrude from the protruding end of the first protrusion 50A of the base material 50 toward the inner door panel 14. The second contact protrusion 54 is formed so as to protrude from the protruding end of the second protrusion 50B of the base material 50 toward the inner door panel 14. The connecting portion 55 connects the contact surface portion 52, the first contact protrusion 53, and the second contact protrusion 54. Specifically, it extends from the edge of the contact surface portion 52 close to the first contact protrusion 53 and the second contact protrusion 54 to the base ends of the first contact protrusion 53 and the second contact protrusion 54. The connecting portion 55 has a portion formed on the surface of the portion between the edge of the contact surface portion 52 of the base material 50 and the base ends of the first protrusion 50A and the second protrusion 50B, a portion formed on the surface of the portion from the base end of the first protrusion 50A to the base end of the first contact protrusion 53, and a portion formed on the surface of the portion from the base end of the second protrusion 50B to the base end of the second contact protrusion 54.

[0047] The conductive layer 51 is formed of a material obtained by, for example, making fine particles of metal or carbon and mixing them into a thermoplastic elastomer to impart conductivity. Further, the resistivity of the conductive layer 51 is greater than the resistivity of the metal inner door panel 14 and less than the resistivity of the decorative panel 20 and the base material 50. The resistance value of the conductive layer 51 is set to a value such that, between the conductive path (body ground member) connected to the vehicle body panel 12 and the passenger (human body), static electricity can be removed without causing pain or shock to the passenger when the static electricity-carrying passenger makes contact.

[0048] As Figure 8 shown, the protruding ends of the first contact protrusion 53 and the second contact protrusion 54 are each located at a position diagonally above their respective base ends and protrude toward the inner door panel 14. As Figure 5 shown, the first contact protrusion 53 and the second contact protrusion 54 further protrude toward the outside of the vehicle body with respect to the end portion on the outside of the vehicle body (outside of the passenger vehicle) of the second fixing portion 37. As Figures 4 to 7 shown, the base end of the first contact protrusion 53 is cylindrical, and the protruding end has four contact pieces 53A. The contact pieces 53A are arranged at equal intervals in the circumferential direction in a manner formed by making a cross-shaped cut into the cylinder. The base end of the second contact protrusion 54 is cylindrical, and the protruding end has four contact pieces 54A. The contact pieces 54A are arranged at equal intervals in the circumferential direction in a manner formed by making a cross-shaped cut into the cylinder.

[0049] When the handle member 31 is assembled to the decorative panel 20 and the door trim 10 is mounted on the vehicle body panel 12, as Figures 8 to 10 shown, the contact pieces 53A of the first contact protrusion 53 and the contact pieces 54A of the second contact protrusion 54 come into contact with the inner surface 14A (inner surface of the passenger vehicle) of the inner door panel 14. The door trim 10 can release the static electricity carried by the passenger from the conductive layer 51 of the handle member 31 to the inner door panel 14 only by the passenger contacting the inner surfaces of the side wall portion 33B, the front wall portion 33C, and the rear wall portion 33D. That is, static electricity can be released by an action such as the passenger gripping the handle 23, which is a normal action when getting out of the vehicle.

[0050] Here, consider the case where a passenger sitting on a vehicle seat gets off the vehicle. When the passenger leaves the vehicle seat, the passenger is charged with static electricity due to triboelectrification. That is, the timing of triboelectrification mostly occurs before the passenger operates the inner handle 22 to unlock the door and holds the pull handle 23 or during the period when the pull handle 23 is held. Therefore, by the passenger holding the pull handle 23 to remove static electricity, it is possible to suppress the discharge of static electricity generated between the passenger and the metal components (such as the body panel 12) of the vehicle when getting off the vehicle. Conventionally, it was considered that the electrical connection of the painted part on the interior side of the door inner panel 14 was insufficient. Therefore, a conduction path was formed in such a way that static electricity flows to the body panel through non-painted parts such as the inner peripheral surface of the mounting hole formed in the body panel. However, even the painted part of the body panel 12 can conduct electricity of a large voltage such as static electricity. Therefore, depending on the structure of the door trim 10, the passenger can release static electricity to the door inner panel 14 only by holding the pull handle 23 when getting off the vehicle.

[0051] As described above, by simply mounting the door trim 10 on the body panel 12, the first contact protrusion 53 and the second contact protrusion 54 of the conductive layer 51 of the pull handle member 31 are in contact with the body panel 12, and thus the static electricity carried by the passenger can be released from the first contact protrusion 53 and the second contact protrusion 54 to the body panel 12. In the known technology, additional components are required to make the door trim and the body panel conduct electricity, but the door trim 10 does not require such components, nor does it require the connection operation between the door trim 10 and the body panel 12 for conduction. Therefore, the door trim 10 can remove the static electricity carried by the passenger with a simple structure without increasing the number of components and manufacturing man-hours.

[0052] In addition, since the conductive layer 51 is made of an elastomer, the first contact protrusion 53 and the second contact protrusion 54 can be elastically deformed. The contact pieces 53A and 54A are in contact with the interior side surface 14A of the door inner panel 14 in a state of elastic deformation. That is, according to the door trim 10, when the passenger holds the pull handle 23, even if the door trim 10 is locally twisted, deformed, etc., at least one of the contact pieces 53A and 54A is in contact with the door inner panel 14, so that the static electricity carried by the passenger can be reliably released to the door inner panel 14. And although the contact pieces 53A and 54A are in contact with the interior side surface 14A of the door inner panel 14 in a state of elastic deformation, the contact pieces 53A and 54A can deform relatively freely independently of each other, and the possibility that all of the contact pieces 53A and 54A are separated from the door inner panel 14 is low. According to such a structure, it is possible to more reliably avoid the situation where the conduction between the conductive layer 51 and the body panel 12 is lost.

[0053] The first contact protrusion 53 and the second contact protrusion 54 are disposed adjacent to the second fixing portion 37. Since the second fixing portion 37 is fixed to the inner door panel 14, when a passenger holds the handle 23, even if a part of the door trim 10 is twisted or deformed, the first contact protrusion 53 and the second contact protrusion 54 adjacent to the second fixing portion 37 are hardly separated from the inner door panel 14. Thus, the state in which at least one of the contact pieces 53A and 54A is in contact with the inner door panel 14 can be maintained.

[0054] The second fixing portion 37 is constituted by a part of the base material 50. When the second fixing portion 37 is formed of a conductive elastomer, the handle member 31 and the vehicle body panel 12 can be easily electrically conducted, but the mounting strength with respect to the inner door panel 14 is insufficient. If the entire handle member 31 is formed of a conductive resin, the handle member 31 and the vehicle body panel 12 can be easily electrically conducted and sufficient mounting strength can be obtained, but problems such as an increase in cost and a poor touch at the contact surface occur.

[0055] To solve such problems, only the necessary minimum part of the door trim 10 is formed of a conductive elastomer. The increase in cost caused by using a conductive resin material can be suppressed and a good touch can be produced at the contact surface. Also, sufficient mounting strength with respect to the inner door panel 14 can be obtained. According to the door trim 10, not only can the static electricity carried by the passenger be reliably released to the vehicle body panel 12, but also the above-described effects can be obtained.

[0056] The handle member 31 is a single member formed by laminating a conductive layer 51 formed of a conductive elastomer on a base material 50 formed of a non-conductive resin. By simply assembling the single handle member 31 to the decorative plate 20 and mounting the door trim 10 to the vehicle body panel 12, a static electricity conduction path can be ensured. That is, no operation process for anti-static measures is required.

[0057] As Figure 4 shown, the first contact protrusion 53 is located above the second fixing portion 37 and the second contact protrusion 54. That is, the first contact protrusion 53 and the second contact protrusion 54 are provided at positions opposite to each other with respect to the second fixing portion 37. When a passenger holds the handle member 31 to open and close the vehicle door 11, there is a case where a part of the door trim 10 rotates in the longitudinal direction ( Figure 10 the direction of the hollow arrow shown) with the second fixing portion 37 as a fulcrum. Even when such rotation occurs, either the first contact protrusion 53 or the second contact protrusion 54 presses against the inner door panel 14, so that a static electricity conduction path can be reliably ensured.

[0058] In the above-described door trim 10, the handle member 31 may be replaced with Figure 11The handle member 70 shown. The handle member 70 is a single member formed by laminating a conductive layer 72 made of a conductive elastomer on a base material 71 made of a non-conductive resin. Regarding the same structure as the handle member 31 in the handle member 70, its description is omitted.

[0059] The base material 71 has a first protrusion 71A, a second protrusion 71B, and a third protrusion 71C. The first protrusion 71A and the second protrusion 71B are respectively configured in the same structure as the first protrusion 50A and the second protrusion 50B of the base material 50. The third protrusion 71C is provided at a position in front of the vehicle with respect to the through hole 37A of the second fixing portion 37. The third protrusion 71C is configured in the same structure as the second protrusion 71B, that is, the second protrusion 50B of the base material 50.

[0060] The conductive layer 72 has a contact surface portion 52, a first contact protrusion 73, a second contact protrusion 74, a third contact protrusion 75, and a connecting portion 76. The first contact protrusion 73, the second contact protrusion 74, and the third contact protrusion 75 are respectively provided at the protruding ends of the first protrusion 71A, the second protrusion 71B, and the third protrusion 71C of the base material 71, and are connected to the contact surface portion 52 by the connecting portion 76. The first contact protrusion 73 and the second contact protrusion 74 are provided at positions closer to the contact surface portion 52 (rearward in the vehicle front-rear direction) than the third contact protrusion 75 and the second fixing portion 37. Further, in the vehicle up-down direction, the first contact protrusion 73 is located above the second fixing portion 37, and the second contact protrusion 74 is located below the second fixing portion 37. The third contact protrusion 75 is provided at a position in front of the vehicle with respect to the through hole 37A of the second fixing portion 37.

[0061] The first contact protrusion 73 is formed so as to face the door inner panel 14 from the protruding end of the first protrusion 71A of the base material 71. The second contact protrusion 74 is formed so as to face the door inner panel 14 from the protruding end of the second protrusion 71B of the base material 71. The third contact protrusion 75 is formed so as to face the door inner panel 14 from the protruding end of the third protrusion 71C of the base material 71. The connecting portion 76 connects the contact surface portion 52, the first contact protrusion 73, the second contact protrusion 74, and the third contact protrusion 75. Specifically, it extends from the end edge of the contact surface portion 52 close to the first contact protrusion 73 and the second contact protrusion 74 to the base ends of the first contact protrusion 73, the second contact protrusion 74, and the third contact protrusion 75. The connecting portion 75 has a portion formed on the surface of the portion between the end edge of the contact surface portion 73 of the base material 71 and the base ends of the first protrusion 71A, the second protrusion 71B, and the third protrusion 71C, a portion formed on the surface of the portion from the base end of the first protrusion 71A to the base end of the first contact protrusion 73, a portion formed on the surface of the portion from the base end of the second protrusion 71B to the base end of the second contact protrusion 74, and a portion formed on the surface of the portion from the base end of the third protrusion 71C to the base end of the third contact protrusion 75.

[0062] The base end of the first contact protrusion 73 is cylindrical, and the protruding end has four contact pieces 73A. The contact pieces 73A are arranged at equal intervals in the circumferential direction in a manner formed by cutting a cross into the cylinder. The base end of the second contact protrusion 74 is cylindrical, and the protruding end has four contact pieces 74A. The contact pieces 74A are arranged at equal intervals in the circumferential direction in a manner formed by cutting a cross into the cylinder. The base end of the third contact protrusion 75 is cylindrical, and the protruding end has four contact pieces 75A. The contact pieces 75A are arranged at equal intervals in the circumferential direction in a manner formed by cutting a cross into the cylinder.

[0063] When a passenger holds the handle member 70 to open and close the vehicle door 11, there is a case where a part of the door trim 10 rotates longitudinally with the second fixing portion 37 as a fulcrum. Even when such rotation occurs, at least one of the first contact protrusion 73, the second contact protrusion 74, and the third contact protrusion 75 presses against the inner door panel 14. Therefore, even when the door trim 10 twists and deforms locally when holding the handle member 70 to open and close the vehicle door 11, a reliable static conduction path can be ensured, and the static electricity carried by the passenger can be reliably released to the body panel 12. In addition, by using the third contact protrusion 75, a more reliable static conduction path can be ensured compared with the handle member 31, and the static electricity carried by the passenger can be more reliably released to the body panel 12.

[0064] In the door trim 10, the handle member 31 can also be replaced with Figure 12 the handle member 80 shown. The handle member 80 is a single member formed by laminating a conductive layer 82 formed of a conductive elastomer on a base material 81 formed of a non-conductive resin. Regarding the same structures as the handle members 31 and 70 in the handle member 80, their descriptions are omitted.

[0065] The base material 81 forms the same structure as the base material 50, but has a second fixing portion 87 with a different structure from the second fixing portion 37. The second fixing portion 87 has a through hole 87A, and its use is the same as that of the through hole 37A provided in the base material 50. The second fixing portion 87 of the base material 81 is larger in the vehicle front-rear direction than the second fixing portion 37 of the base material 50, and the part below the second fixing portion 37 is also larger in the vehicle front-rear direction. The base material 81 has a first protrusion 81A and a second protrusion 81B. The first protrusion 81A has the same structure as the first protrusion 50A of the base material 50. The second protrusion 81B is provided with the same structure as the second protrusion 50B, but its position in the vehicle front-rear direction is different from that of the second protrusion 50B. The second protrusion 81B is provided at a position in front of the through hole 87A in the vehicle front-rear direction. In addition, it is provided at a position in front of the third contact protrusion 75 of the handle member 70 in the vehicle front-rear direction.

[0066] The conductive layer 82 has a contact surface portion 52, a first contact protrusion 83, a second contact protrusion 84, and a connecting portion 85. The first contact protrusion 83 is provided at a position rearward and above the vehicle than the second fixing portion 87. The second contact protrusion 84 is provided at a position forward and below the vehicle than the through hole 87A of the second fixing portion 87. The through hole 87A is located between the first contact protrusion 83 and the second contact protrusion 84 in the vehicle front-rear direction.

[0067] The first contact protrusion 83 is formed so as to face the door inner panel 14 from the protruding end of the first protrusion 81A of the base material 81. The second contact protrusion 84 is formed so as to face the door inner panel 14 from the protruding end of the second protrusion 81B of the base material 81. The connecting portion 85 connects the contact surface portion 52, the first contact protrusion 83, and the second contact protrusion 84. Specifically, it extends from the end edge of the contact surface portion 52 close to the first contact protrusion 83 to the base ends of the first contact protrusion 83, the second contact protrusion 84, and the third contact protrusion 85. The connecting portion 85 has a portion formed on the surface of the portion between the end edge of the contact surface portion 52 of the base material 81 and the base ends of the first protrusion 81A and the second protrusion 81B, a portion formed on the surface of the portion from the base end of the first protrusion 81A to the base end of the first contact protrusion 83, and a portion formed on the surface of the portion from the base end of the second protrusion 81B to the base end of the second contact protrusion 84.

[0068] The first contact protrusion 83 is provided with the same structure as the first contact protrusion 53. Specifically, the base end is cylindrical, and the protruding end has four contact pieces 83A. The contact pieces 83A are arranged at equal intervals in the circumferential direction in a manner formed by cutting a cross-shaped notch into the cylinder. The second contact protrusion 84 is provided with the same structure as the second contact protrusion 54, but the position in the vehicle front-rear direction is different from that of the second contact protrusion 54. The base end of the second contact protrusion 84 is cylindrical, and the protruding end has four contact pieces 84A. The contact pieces 84A are arranged at equal intervals in the circumferential direction in a manner formed by cutting a cross-shaped notch into the cylinder.

[0069] When a passenger holds the handle member 80 to open and close the vehicle door 11, there is a case where the door trim 10 rotates longitudinally with the second fixing portion 8737 as a fulcrum at a local part. Even in such a case of rotation, at least one of the contact pieces 83A and the contact pieces 84A presses against the door inner panel 14. Therefore, even when the door trim is locally twisted and deformed when holding the handle member 80 to open and close the vehicle door 11, a reliable static conduction path can be ensured, and the static electricity carried by the passenger can be reliably released to the vehicle body panel 12.

[0070] The dimension of the second fixing portion 87 of the handle member 80 in the vehicle front-rear direction is larger than that of the second fixing portion 37 of the base material 50. Therefore, the handle member 80 can be fixed to the door inner panel 14 more stably. The dimension of the second fixing portion 87 and the portion below it in the vehicle front-rear direction is larger than that of the second fixing portion 37 and the portion below it of the base material 71. Therefore, there is a possibility that the longitudinal rotation around the second fixing portion 87 becomes larger. However, the second contact protrusion 84 is provided at a position in front of the vehicle relative to the third contact protrusion 75 of the handle member 70. Therefore, even when the rotation is large, at least one of the contact piece 83A and the contact piece 84A presses against the door inner panel 14, and a reliable conduction path for static electricity can be ensured. Thus, even when the vehicle door 11 is opened and closed while holding the handle member 80 and greater torsion and deformation occur locally in the door trim, the static electricity carried by the passengers can be reliably released to the vehicle body panel 12.

[0071] In the door trim 10, the handle member 31 can also be replaced with Figure 13 the handle member 100 shown. The handle member 100 may also have a conductive layer 101 with a structure different from that of the conductive layer 51 of the handle member 31. Specifically, the conductive layer 101 has a first contact protrusion 102 and a second contact protrusion 103 with structures different from those of the first contact protrusion 53 and the second contact protrusion 54 of the conductive layer 51. The other structures of the conductive layer 101 are the same as those of the conductive layer 51.

[0072] The first contact protrusion 102 and the second contact protrusion 103 of the conductive layer 101 protrude from the base material 50 and have protruding ends in the shape of bulges toward the outside of the vehicle. Each protruding end is formed in a cylindrical shape extending along the vehicle front-rear direction. Moreover, when the door trim 10 is installed on the vehicle body panel 12, as Figure 13 shown, it contacts the vehicle interior side surface 14A of the door inner panel 14 in a state where the top end of the cylindrical shape is flattened in the vehicle interior-exterior direction (the interior-exterior direction of the vehicle).

[0073] The door trim 10 contacts the vehicle interior side surface 14A of the door inner panel 14 in a state where the protruding ends of the first contact protrusion 102 and the second contact protrusion 103 are elastically deformed in the vehicle interior-exterior direction (the interior-exterior direction of the vehicle). The first contact protrusion 102 and the second contact protrusion 103 can be deformed relatively freely independently of each other, and a state where at least one of the first contact protrusion 102 and the second contact protrusion 103 contacts the door inner panel 14 can be maintained. The situation where the conduction between the conductive layer 101 and the vehicle body panel 12 is lost can be more reliably avoided, and the static electricity carried by the passengers can be reliably released to the vehicle body panel 12.

[0074] The technology described in the specification of this application can also be applied to a door handle configured in a form extending along the vertical direction on a door trim. In addition, the technology described in the specification of this application can also be applied to vehicle interior parts such as a side trim panel having a gripping portion for a passenger to maintain a posture, and a ceiling interior part having an auxiliary handle. Moreover, the technology described in the specification of this application can be applied to passenger vehicles such as trains as ground passenger vehicles, game vehicles, airplanes and helicopters as flight passenger vehicles, and ships and submarines as sea and underwater passenger vehicles.
