Description

The present invention relates to interior materials for vehicles used in the ceilings of vehicles.

The interior materials that make up the ceiling of a vehicle such as an automobile are equipped with a variety of functional components, including sun visors, vanity mirrors, vanity lamps, and map lamps. Since the more lighting devices there are, the more wiring required for them. Patent Document 1 below describes a lamp unit installed on the back surface of the sun visor (the surface that faces the interior of the vehicle cabin in the shaded position, and the surface that faces the occupants in the shaded position) that serves as both a vanity lamp and a map lamp, in order to reduce the amount of wiring required.

Japanese Patent Application Laid-Open No. 2007-196955

The technology described in Patent Document 1 aims to reduce the number of parts by combining the vanity lamp and map lamp, but it is necessary to route the wiring for the lighting device inside the pivot shaft that rotatably holds the sun visor, which is thought to lead to an increase in the number of parts and increased costs. Furthermore, since the lighting device is installed in the sun visor, the sun visor itself becomes thicker, and the sun visor itself needs to be designed to emit light in order to be used as a map lamp, which is thought to reduce the design freedom of the sun visor.

The present invention was made in consideration of these circumstances, and its objective is to provide a vehicle interior material that can enhance the design of the ceiling while reducing the number of parts and costs.

In order to solve the above problems, the vehicle interior material of the present invention comprises:
An interior material for a vehicle that covers a roof panel of a vehicle and includes a roof trim, a sun visor, a vanity mirror, and a lamp unit,
The roof trim is formed with a recess for accommodating the sun visor in a stored position along the ceiling of the vehicle compartment,
The recess is
a pair of side wall portions opposed to each other in a width direction of the vehicle;
a bottom wall portion that connects upper ends of the pair of side wall portions to form a bottom surface of the recess and faces a plate surface of the sun visor in the retracted position;
and
the vanity mirror is provided on the back surface of the sun visor or on the bottom wall portion, the back surface facing the passenger compartment when the vanity mirror is in a light-blocking position facing the windshield,
The lamp unit is arranged on the back side of the roof trim along at least one of the pair of side wall portions, and is characterized by realizing a first emission state in which light is emitted downward from the edge of the recess in the roof trim, and a second emission state in which light is emitted from at least one of the side wall portion and the bottom wall portion when the sun visor is in the shading position.

The vehicle interior material disclosed in this application uses light from the lamp unit in its first emission state as a map lamp, and light from its second emission state as a vanity lamp when the vanity mirror is in use. Furthermore, while installing a lamp unit in the sun visor itself requires wiring to be routed inside the pivot shaft, the vehicle interior material disclosed in this application requires wiring only on the back side of the roof trim. Furthermore, the vehicle interior material disclosed in this application allows a single lamp unit to function as both a map lamp and a vanity lamp, thereby reducing the number of parts and costs. Furthermore, the sun visor itself is configured to be stored within the recess, allowing for a neatly designed ceiling.

In the above configuration, the lamp unit has a light guide with a generally L-shaped cross section arranged on the back side of the roof panel along the location where the side wall and bottom wall are connected, and the light guide has a shape in which a side wall facing portion that is a portion that fits along the side wall is connected to a bottom wall facing portion that is a portion that fits along the bottom wall, and the lamp unit can be configured to emit light from the tip of the side wall facing portion through the edge of the recess to achieve the first emission state, and to emit light from the bottom wall facing portion through the bottom wall to achieve the second emission state.

This vehicle interior material incorporates the lamp unit configuration, allowing the first and second emission states to be achieved with a simple configuration.

In the above configuration, the roof trim can include a first ceiling material that serves as the main covering for the roof panel, and a second ceiling material that extends in the width direction of the vehicle between the first ceiling material and the front window, covers the interior side of the vehicle at the front end of the roof panel, and forms an overhead module on which various functional components are mounted, and the recess can be formed in the second ceiling material.

In this type of vehicle interior material, each component is modularized, simplifying manufacturing and improving the design of the vehicle ceiling. Furthermore, when this type of vehicle interior material is used in a typical vehicle, the boundary between the first and second ceiling materials is located rearward and downward from the upper edge of the front window, making it difficult for occupants in the driver's seat or passenger seat to see. This also contributes to improved design.

In the above configuration, the sun visor can have a visor body and a pair of shafts that protrude in the width direction from each of the two side surfaces of the vehicle, and the shafts are rotatably held in each of the pair of side walls, making the sun visor rotatable.

This vehicle interior material supports the sun visor from both ends and can hold the sun visor in any position. Unlike conventional sun visors, the sun visor itself does not have a mechanism for holding the visor in any position, allowing for a lighter sun visor. Furthermore, because the sun visor shaft supports the visor body at both ends, it can be thinner than conventional sun visors. Furthermore, because the sun visor shaft can be fixed to the visor body, it is possible to configure the visor body with only a pair of shafts at each end. As a result, the visor body itself is lighter and thinner than conventional sun visors, and can be formed into a rectangular shape without the notches found in conventional sun visors. Therefore, using a sun visor with this configuration improves the design of the vehicle interior.

This invention makes it possible to provide interior materials for vehicles that can enhance the design of the ceiling while reducing the number of parts and costs.

The vehicle interior material according to an embodiment of the present invention is a vehicle interior material 10 that is placed on the ceiling of a vehicle (automobile). The vehicle interior material 10 of this embodiment will be described with reference to Figures 1 to 11. Note that in some of the drawings, directions are indicated using the symbols Fr, Rr, L, R, U, and D, which respectively represent the front and rear of the vehicle, the left and right sides in the vehicle width direction (the width direction of the vehicle), and the upper and lower sides.

As shown in Figures 1 to 3, the vehicle interior material 10 of this embodiment is a so-called roof trim that covers the interior of the vehicle cabin (vehicle compartment) on the ceiling side of the vehicle body. Specifically, the vehicle interior material 10 covers the interior side of the vehicle cabin of a roof panel 12 that constitutes the ceiling of the vehicle body and front pillar panels that constitute the front pillars 16 on the front side of the vehicle body (on both sides of the front window 14 in the vehicle width direction). As shown in Figure 3, the roof panel 12 is composed of a generally plate-shaped panel main body 12A and a frame 12B that is fixed to the interior side of the panel main body 12A and includes at least a portion along the outer edge of the panel main body 12A.

The vehicle interior material 10 is broadly divided into two ceiling materials 20 and 22. The first ceiling material 20 covers most of the roof panel 12 except for the front end. This first ceiling material 20 has a conventionally well-known configuration. As shown in FIG. 3, for example, it comprises a substrate 24 made of a porous material, in which, from the surface side, a glass fiber mat, urethane foam, another glass fiber mat, and a nonwoven fabric are laminated, with a skin material 26 attached. The first ceiling material 20 is formed by press molding from a flat plate-shaped member. The first ceiling material 20 is relatively lightweight and has sufficient rigidity to prevent deflection due to its own weight. Therefore, when attaching a functional component such as a center lamp to the roof, a through-hole is formed in the first ceiling material 20 so that the component can be fixed to the roof panel 12. As shown in FIG. 3, the first ceiling material 20 is attached to the frame 12B of the roof panel 12 with bolts 28 to cover the opening formed by the frame 12B.

The second ceiling material 22 is disposed forward of the first ceiling material 20. Specifically, the second ceiling material 22 constitutes an overhead module disposed at the front end of the vehicle ceiling, extending in the vehicle width direction. The second ceiling material 22 covers not only the interior side of the front end of the roof panel 12, but also the interior sides of the front pillar panels on both sides of the vehicle width direction. In other words, the second ceiling material 22 extends in the vehicle width direction between the first ceiling material 20 and the front windshield 14, covers the interior side of the front end of the roof panel 12, and comprises an overhead module portion 30 constituting an overhead module on which various functional components are mounted, and a pair of pillar garnish portions 32 covering the interior side of the front pillar panels. The overhead module portion 30 is primarily composed of a module main body 40, which serves as a base for attaching various functional components and serves as the main body covering the front end of the roof panel 12.

The module body 40 is formed by injection molding from a thermoplastic resin such as polypropylene. As shown in FIG. 3, this module body 40 covers the boundary between the panel body 12A and the front window 14, and the front edge 20A including the mounting portion of the panel body 12A, frame 12B, and first ceiling material 20, and is fixed to the frame 12B using clips 40A or the like. In other words, the second ceiling material 22 is configured to overlap the front edge 20A of the first ceiling material 20 from below and support the first ceiling material 20.

The pair of pillar garnish sections 32 are molded integrally with the module body 40 using the above-mentioned thermoplastic resin, forming a continuous design with the overhead module section 30. As long as the second ceiling material 22 is configured so that the overhead module section 30 and the pair of pillar garnish sections 32 form a continuous design, the overhead module section 30 and the pillar garnish section 32 may be configured as separate components, or the overhead module section 30 may be divided and a portion of the overhead module section 30 and the pillar garnish section 32 may be formed integrally.

The second ceiling material 22 has a lower porosity (almost zero) than the first ceiling material 20. In other words, the second ceiling material 22 is more rigid than the first ceiling material 20, and functional components do not need to be fixed to the roof panel 12, but can be attached to the module body 40 itself. The second ceiling material 22 can also firmly support the front edge 20A of the first ceiling material 20 from below.

Next, the overhead module unit 30 will be described in detail. The overhead module unit 30 is provided with a sun visor 42, vanity mirror 44, lamp unit 46, and assist grip 48, corresponding to each of the driver's seat and passenger seat of the vehicle. The overhead module unit 30 is basically symmetrical, with the one on the driver's seat side (right side in the vehicle width direction) and the one on the passenger seat side (left side in the vehicle width direction) having the same configuration. Therefore, the following description will focus on the one on the driver's seat side. However, when it is necessary to distinguish between the driver's seat side and the passenger seat side, the one on the driver's seat side (right side) will be designated with an R, and the one on the passenger seat side will be designated with an L.

The sun visor 42 is held so that it can rotate around an axis extending in the vehicle width direction. As shown in Figure 3, the sun visor 42 can be changed between a stored position in which it is positioned along the ceiling and an extended position in which it faces the windshield 14.

As shown in Figures 4 and 5, the module body 40 has a recess 50 that accommodates the sun visor 42 in the retracted position. As shown in Figure 4, the recess 50 is formed by a side wall 52 having a side surface facing right, a side wall 53 having a side surface facing left, and a bottom wall 54 that connects the upper ends of the pair of side walls 52, 53 to form the bottom of the recess 50. The sun visor 42 has a plate-shaped visor body 42A and a pair of shafts 42B (see Figure 3) that protrude outward from each of the side surfaces on both sides of the visor body 42A in the vehicle width direction, and each of the pair of shafts 42B is rotatably held by the pair of side walls 52, 53 of the recess 50. Although detailed explanation is omitted, bearing members that support the shaft 42B are provided on the inside of the pair of side walls 52, 53. The sun visor 42 is supported at any rotational position by these bearing members, so that it can be held in any position between the stored position and the deployed position. In other words, it will not rotate due to vibrations caused by driving, for example, but can easily rotate when force is applied by the occupant.

Furthermore, when the sun visor 42 is in the retracted position, its upper surface faces the bottom wall 54, and its lower surface is substantially flush with the lower ends of the pair of side walls 52, 53 (the lower surface of the module body 40). In other words, when the sun visor 42 is in the retracted position, as shown in Figure 2, the second ceiling material 22 has a flat surface, resulting in a neat and sleek design.

As shown in Figure 4, a vanity mirror 44 is provided on the bottom wall 54 of the recess 50. This vanity mirror 44 can be used by rotating the sun visor 42 from its retracted position to a downwardly extending, light-blocking state. While the usage state of the vanity mirror 44 is not shown, a knob 44A is provided at the rear end that can be used by placing a finger on it, and the rear end can be lowered around the front end as a rotation axis to place the vanity mirror in usage.

Next, we will explain the lamp unit 46, which also functions as a vanity lamp to illuminate the vanity mirror 44 when it is in use. The lamp unit 46 is provided on each of the driver's seat side and passenger seat side, and is composed of two lighting devices 60, 61 (four in total on the second ceiling material 22, as shown in Figure 1) provided on the back (top) side of the module main body 40, corresponding to each of a pair of side wall portions 52, 53. These lighting devices 60, 61 have a substantially similar configuration, so we will explain the lighting device 60 located on the outer side in the vehicle width direction on the driver's seat side as a representative.

The lighting device 60 is composed of a light source unit 62, a light guide 64, and a lens member 66. The light guide 64 is longitudinal and generally L-shaped in cross section, extending in the fore-and-aft direction of the vehicle. As shown in Figure 5, the light guide 64 is arranged along the connection between the side wall 53 and bottom wall 54 of the recess 50, covering the connection from the back side. In other words, the light guide 64 has a shape formed by connecting a side wall facing portion 70, which faces the back surface of the side wall 53 and runs along the side wall 53, and a bottom wall facing portion 72, which faces the back surface (upper surface) of the bottom wall 54 and runs along the bottom wall 54.

As shown in Figures 6 and 7, the light source unit 62 is disposed above the light guide 64. The light source unit 62 has multiple LEDs 62A, 62B mounted on the underside of the LED board 62C in two rows aligned in the front-to-rear direction. The first LEDs 62A are aligned in the front-to-rear direction along the outer edge of the bottom wall facing portion 72 in the vehicle width direction (this can be considered the connecting portion between the bottom wall facing portion 72 and the side wall facing portion 70, or the upper end of the side wall facing portion 70). The second LEDs 62B are aligned along the inner edge of the bottom wall facing portion 72 in the vehicle width direction. The light source unit 62 is configured so that light from the first LED 62A and light from the second LED 62B are incident independently from the upper surface of the light guide 64.

On the other hand, light incident on the light guide 64 is emitted from the cabin side surface. The lens member 66 is made of a translucent material and, as shown in FIG. 8, forms the portion of the module main body 40 that faces the light guide 64. Specifically, as shown in FIGS. 6 to 8, the lens member 66 has a side wall forming portion 74 that constitutes the side wall portion 53 of the module main body 40, a bottom wall forming portion 76 that extends from the upper end of the side wall forming portion 74 inward in the vehicle width direction to form part of the bottom wall portion 54, and a recess edge forming portion 78 that extends from the lower end of the side wall forming portion 74 outward in the vehicle width direction to form the edge of the recess 50 (a part of the portion extending from the lower end of the side wall portion 53 outward in the vehicle width direction). This allows light emitted from the cabin side surface of the light guide 64 to be emitted toward the cabin.

The light guide 64 transmits light from the first LED 62A through the sidewall-facing portion 70 and emits it from the lower end of the sidewall-facing portion 70. A pattern 78A is formed on the recess edge forming portion 78 of the lens member 66, and light corresponding to the pattern 78A is emitted toward the vehicle cabin. Furthermore, the lower end of the sidewall-facing portion 70 of the light guide 64 has a pattern-shaped notch cut into the edge 70A on the inner side in the vehicle width direction (left side in Figure 6), and light is emitted toward the vehicle cabin from the connecting portion (corner) of the lens member 66 between the sidewall-facing portion 74 and the recess edge forming portion 78. In other words, turning on the first LED 62A achieves a first emission state in which light is emitted downward from the edge of the recess 50.

The bottom wall-facing portion 72 of the light guide 64 has a blasted lower surface 72A, which allows light from the second LED 62B to be diffused from the lower surface 72A and emitted downward through the lens member 66. The light emitted from the bottom wall-facing portion 72 is emitted toward the vehicle interior when the sun visor 42 is in the in-use state (light-blocking position). In other words, turning on the second LED 62B achieves a second emission state in which light is emitted from the bottom wall 54 when the sun visor 42 is in the light-blocking position. The second LED 62B is turned on when the vanity mirror 44 is opened, and turned off when the vanity mirror 44 is closed. The light emitted in the second emission state is used as a vanity lamp.

The light emitted by the first LED 62A in the first emission state is controlled by a switch 80 shown in FIGS. 1 and 2 . When an occupant operates the switch 80 to turn on the first LED 62A, the light emitted in the first emission state functions as a map lamp that illuminates the area around the occupant's hands. However, because the lighting device 60 of the lamp unit 46 is provided on the outer side of the sun visor 42 in the vehicle width direction as shown in FIG. 9 , when the side door 82 is open, the light emitted by the first LED 62A in the first emission state irradiates an area from the seat surface of the seat 84 to the outside of the vehicle (the range of _θ1 in FIG. 9 ). In other words, the light also functions as a welcome lamp that illuminates the area around the feet of occupants getting in and out of the vehicle. Furthermore, the lamp unit 46 can also emit light in the first emission state toward the upper portion of the side door 82 on the interior side of the vehicle (in the range of _θ2 in FIG. 9 ) by operating the switch 80. This allows the light from the lamp unit 46 to be used for nighttime illumination. Therefore, according to the present vehicle interior material 10, one lamp unit 46 can have multiple functions, which reduces the number of lighting devices and leads to cost reductions.

The switch 80 is provided for each of the driver's seat side lamp unit 46R and the passenger seat side lamp unit 46L, and both are provided on the outside of the sun visor 42 in the vehicle width direction relative to the module main body 40. In other words, the switch 80 for the lamp unit 46 (more specifically, the first LED 62A) is not provided between the two seats (in the center of the vehicle), but in a position away from the occupant in the adjacent seat. This allows the occupant to operate the switch 80 without worrying about the occupant sitting next to them.

Next, the assist grip 48 will be described. As shown in Figures 2 and 4, the assist grip 48 is provided at the boundary between the first ceiling material 20 and the second ceiling material 22, and is configured to be able to be pulled out from between the first ceiling material 20 and the second ceiling material 22. The second ceiling material 22 has a pillar garnish portion 32 and an overhead module portion 30 that continues from the upper end of the pillar garnish portion 32. In other words, the portion of the overhead module portion 30 that extends rearward from the upper end of the pillar garnish portion 32 functions as a rearward extension portion 30A, and the assist grip 48, an example of a pull-out member, can be pulled out from between the rear end of the rearward extension portion 30A and the first ceiling material 20.

As shown in Figures 10 and 11, the assist grip 48 includes a flexible, strip-shaped band member 90 and a knob member 92 that can be gripped by an occupant's fingers. In its normal state, as shown in Figure 8, one end 90A of the band member 90 is fixed inside the second ceiling member 22 and extends rearward toward the passenger compartment, while the other end 90B is folded forward so that the other end 90B extends significantly forward beyond the one end 90A. In other words, the folded portion 90C of the band member 90 is housed inside the second ceiling member 22 and protrudes rearward. The one end 90A is fixed to the roof panel 12 by a fixing member 94, penetrating the first ceiling member 20. The knob member 92 is arranged near the portion of the band member 90 that protrudes from the second ceiling material 22, i.e., the folded portion 90C, when the band member 90 is inserted through the band member 90. The knob member 92 is also slidable along the band member 90.

With this configuration, when an occupant grasps the knob member 92 and pulls it rearward, the folded portion 90C is shifted rearward, while the other end 90B is moved rearward, as shown in FIG. 11 . The other end 90B is flanged, and this flange abuts against a stopper 95 fixed to the inner surface of the second ceiling member 22, preventing further withdrawal. This state is shown in FIG. 4 , allowing the occupant to grasp the band member 90. Incidentally, when the band member 90 is pulled out, it attempts to return to the shape shown in FIG. 10 , so the pulled-out portion bulges out in the vehicle width direction, making it easy for the occupant to grasp. Furthermore, when the assist grip 48 is stowed, if the other end 90B of the band member 90 is pushed forward, the restoring force of the band member 90 causes the other end 90B to move forward on its own. In other words, the assist grip 48 with this configuration is easy to stow. Furthermore, because only the strip-shaped band member 90 fits inside the second ceiling material 22, it does not require a large space. In other words, as shown in Figure 5, the area where the assist grip 48 is stored also contains the side airbag 96, but the assist grip 48 can be stored without interfering with these.

The vehicle interior material 10 of this embodiment also includes a card holder 98 as another drawer member. As shown in Figures 2 and 4, the card holder 98 can be drawn out from between the two sun visors 42 of the module main body 40, that is, from between the center of the module main body 40 in the vehicle width direction and the first ceiling material 20.

As described above, with the vehicle interior material 10 of this embodiment, various functional parts are attached to the second ceiling material 22, which is more rigid than the first ceiling material 20, making it possible to simplify vehicle manufacturing operations compared to attaching functional parts to the roof panel 12 by penetrating the first ceiling material 20. Furthermore, because the second ceiling material 22 can be molded by injection molding, it is possible to achieve a unified design that takes into account the functional parts, thereby enhancing the interior design of the vehicle.
