Description

Technical Field

[0001] The technology described herein relates to a vehicle headliner interior component. Background Art

[0002] A vehicle ceiling interior component includes a plate member in a plate-like shape and a reinforcing member (resin foam member) joined to the upper surface of the plate member. The plate member including the reinforcing member can increase its rigidity. An example of such a vehicle ceiling interior component is disclosed in Japanese Unexamined Utility Model Application Publication No. Sho 60-87744.

[0003] In such a construction including a reinforcing member joined to a plate member, the material of the plate member may be different from the material of the reinforcing member. If the linear expansion coefficient of the reinforcing member is greater than the linear expansion coefficient of the plate member, the following problems may result. When a vehicle including the above-mentioned plate member and reinforcing member is used in a cold region and the temperature of the plate member and the reinforcing member drops, the reinforcing member shrinks much more than the plate member. This generates stress acting on the plate member, and the plate member may wrinkle. In order to avoid such problems, a material with a larger linear expansion coefficient may be used for the plate member, or the basis weight of the material may be increased to increase the rigidity of the plate member. However, in the case of such a construction, the material of the plate member cannot be freely selected, and the weight of the plate member may increase. Summary of the invention

[0004] The technology described herein is made in view of the above circumstances. An object of the invention is to provide a vehicle ceiling interior trim component that is less prone to wrinkles on a plate member.

[0005] The present disclosure relates to a vehicle ceiling interior component, which includes: a plate member, which is a plate-shaped member and is configured as a ceiling of a vehicle cabin; and a reinforcing member, which has an elongated shape and extends in the longitudinal direction. The reinforcing member is arranged on the vehicle outer side surface of the plate member and is made of a material having a linear expansion coefficient greater than the linear expansion coefficient of the material of the plate member. The reinforcing member includes: a first fixing portion and a second fixing portion, both of which are fixed to the vehicle outer side surface of the plate member and arranged along the longitudinal direction; and a connecting portion, which connects the first fixing portion and the second fixing portion and is away from the vehicle outer side surface of the plate member.

[0006] In the above-mentioned configuration, the reinforcing member includes: a first fixing portion and a second fixing portion, both of which are fixed to the outer side surface of the vehicle of the plate member; and a connecting portion, which connects the first fixing portion and the second fixing portion and is away from the outer side surface of the vehicle of the plate member. According to this configuration, if the temperature of the reinforcing member drops and the reinforcing member shrinks, the connecting portion expands or shrinks in the longitudinal direction of the reinforcing member to absorb the thermal shrinkage of the reinforcing member. Therefore, the first fixing portion and the second fixing portion can shrink independently. The reinforcing member includes a first fixing portion and a second fixing portion, both of which are individually joined to the plate member and can be deformed individually. In the case of this configuration, as the reinforcing member shrinks, large stress is less likely to act locally on the plate member and wrinkles are less likely to be generated on the plate member. In the case where the first fixing portion and the second fixing portion are connected by the connecting portion, the reinforcing member is constructed as a single component and can be easily handled and the rigidity of the reinforcing member is increased compared with the configuration including the first fixing portion and the second fixing portion as separate components.

[0007] The connecting portion may include a first end portion continuous with the first fixing portion, a second end portion continuous with the second fixing portion, and an intermediate portion extending from the first end portion to the second end portion and away from the vehicle outer side surface of the plate member. Therefore, the reinforcing member having the above-mentioned configuration can be easily formed.

[0008] The middle portion may have a curved shape. According to such a configuration, a connection portion connecting the first fixing portion and the second fixing portion, which is away from the vehicle outer side surface of the plate member, can be easily realized.

[0009] The plate member may include a recess on the outer side surface of the vehicle, and the recess may extend along the airbag on the outer side surface of the vehicle and adjacent to the reinforcing member. The connecting portion may include a notch, and the recess may be continuous with the connecting portion via the notch.

[0010] If the airbag is activated, the plate member is pushed by the inflated airbag and bends along the concave portion. Therefore, the airbag can be inflated smoothly. In the case where the connecting portion is connected to the concave portion at the notch, the plate member can be bent smoothly along the concave portion.

[0011] The reinforcing member may further include a third fixing portion fixed to the outer side surface of the vehicle of the plate member, and a first connecting portion connecting the second fixing portion and the third fixing portion. The first fixing portion, the second fixing portion and the third fixing portion may be arranged along the longitudinal direction, and the second fixing portion may be arranged between the first fixing portion and the third fixing portion.

[0012] By changing the configuration of the connecting portion and the first connecting portion, the length of the second fixing portion can be changed, and the degree of contraction of the second fixing portion between the first connecting portion and the second connecting portion can be changed.

[0013] The reinforcing member may also include a protruding portion protruding from the vehicle outer side surface of the second fixing portion toward the vehicle panel, and the protruding portion may be between the connecting portion and the first connecting portion. If the plate member is deformed or moved toward the roof panel, the protruding end surface of the protruding portion contacts the roof panel. Therefore, the plate member 30 is less likely to move further toward the roof panel. This increases the rigidity of the plate member.

[0014] The first fixing portion and the second fixing portion can be fixed to the vehicle outer side surface of the plate member with an adhesive. Therefore, the first fixing portion and the second fixing portion are easily and firmly fixed to the vehicle outer side surface of the plate member.

[0015] The vehicle inner side surfaces of the first fixing portion and the second fixing portion may be fixed to the vehicle outer side surface of the plate member. The first fixing portion and the second fixing portion are firmly fixed to the vehicle outer side surface of the plate member by surface contact.

[0016] The second fixing portion may include a rib protruding from the vehicle inner side surface of the second fixing portion. This increases the rigidity of the reinforcing member.

[0017] The first fixing portion, the second fixing portion and the third fixing portion may include ribs protruding from their vehicle outer side surfaces. This increases the rigidity of the reinforcing member.

[0018] According to the present disclosure, it is possible to provide a vehicle ceiling interior part in which wrinkles are less likely to be generated on a plate member. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Reference Figures 1 to 10 One embodiment of the present disclosure is described in detail. In this section, a ceiling interior component 20 for a vehicle will be described as an example of a vehicle ceiling interior component. Figure 1 As shown, the ceiling interior component 20 includes a plate-like plate member 30 (interior component body) and a reinforcing member 40 arranged on the vehicle outer side surface of the plate member 30. The reinforcing member 40 is Figure 1 Indicated by dotted line.

[0030] like Fig. 9 As shown, the plate member 30 covers the roof panel 10 (vehicle panel) from the inside of the vehicle and is configured as a ceiling of the vehicle cabin. The plate member 30 can be made of a synthetic resin material such as polyurethane foam; however, the material of the plate member 30 may not be limited to a synthetic resin material.

[0031] like Figure 2As shown, the reinforcing member 40 has a longitudinal shape that is long in the front-rear direction of the vehicle. The reinforcing member 40 is arranged on the side edge portion of the vehicle rear edge portion of the plate member 30. The reinforcing member 40 is made of a synthetic resin such as polypropylene and polyethylene, and the material of the reinforcing member 40 has a linear expansion coefficient greater than that of the material of the plate member 30. The reinforcing member 40 includes a first fixing portion 41, a second fixing portion 42, a third fixing portion 43, a first connecting portion 51 and a second connecting portion 52. An adhesive layer 31 is provided on each of the first fixing portion 41, the second fixing portion 42 and the third fixing portion 43. Therefore, the first fixing portion 41, the second fixing portion 42 and the third fixing portion 43 are fixed to the vehicle outer side surface 30A of the plate member 30 using an adhesive layer 31 (such as a hot melt adhesive). The first fixing portion 41, the second fixing portion 42 and the third fixing portion 43 are away from each other. The first connecting portion 51 connects the first fixing portion 41 and the second fixing portion 42 adjacent to each other. The second connecting portion 52 connects the second fixing portion 42 and the third fixing portion 43 adjacent to each other.

[0032] The first fixing portion 41, the second fixing portion 42, and the third fixing portion 43 are arranged along the longitudinal direction of the reinforcing member 40. The first fixing portion 41 and the second fixing portion 42 (a pair of fixing portions) are arranged along the longitudinal direction of the reinforcing member 40 and are connected to each other through the first connecting portion 51. The second fixing portion 42 and the third fixing portion 43 (a pair of fixing portions) are arranged along the longitudinal direction of the reinforcing member 40 and are connected to each other through the second connecting portion 52. Figure 6 and Figure 7 As shown, the first connection portion 51 and the second connection portion 52 are not joined to the vehicle outer side surface 30A of the plate member 30 and are away from the vehicle outer side surface 30A.

[0033] like Figures 2 to 5 As shown, the first connection portion 51 extends along the short side direction (width direction) of the reinforcing member 40. Figure 6 As shown, the first connecting portion 51 has a longitudinal direction ( Figure 6 In more detail, the first connecting portion 51 includes a middle portion 51A, a first end portion 51B and a second end portion 51C. The middle portion 51A is away from the outer side surface 30A of the vehicle. The first end portion 51B and the second end portion 51C are in contact with the outer side surface 30A of the vehicle. The first connecting portion 51 is connected to the first fixing portion 41 via the first end portion 51B and to the second fixing portion 42 via the second end portion 51C. The first connecting portion 51 is U-shaped and extends from the first end portion 51B to the second end portion 51C in a manner bent away from the outer side surface 30A of the vehicle. Figure 7As shown, the second connection portion 52 extends along the short side direction (width direction) of the reinforcing member 40. Figure 7 As shown, the second connecting portion 52 has a longitudinal direction ( Figure 7 The second connecting portion 52 is a U-shaped cross-section taken along the left and right directions of the vehicle. In more detail, the second connecting portion 52 includes a middle portion 52A, a first end portion 52B and a second end portion 52C. The middle portion 52A is away from the outer side surface 30A of the vehicle. The first end portion 52B and the second end portion 52C are in contact with the outer side surface 30A of the vehicle. The second connecting portion 52 is connected to the second fixing portion 42 via the first end portion 52B and is connected to the third fixing portion 43 via the second end portion 52C. The second connecting portion 52 is U-shaped and extends from the first end portion 52B to the second end portion 52C in a manner bent away from the outer side surface 30A of the vehicle.

[0034] like Figure 2 As shown, the airbag 11 (curtain airbag) is arranged adjacent to the reinforcement member 40 located on the vehicle outer side of the panel member 30. The airbag 11 extends in the vehicle front-rear direction and is arranged in front of the reinforcement member 40 (at the Figure 1 ), such as Figure 1 . The airbag 11 is arranged to correspond to the vehicle passenger space, and the reinforcing member 40 is arranged to correspond to the luggage space. The portion of the plate member 30 corresponding to the vehicle passenger space is provided with components of the airbag 11 and has effective rigidity. However, the portion of the plate member 30 corresponding to the luggage space is not provided with an airbag, and therefore, the reinforcing member 40 is arranged on the portion of the plate member 30 corresponding to the luggage space to increase rigidity.

[0035] like Figure 2 and Figure 3 As shown, the plate member 30 includes a first groove 32 (recess) and a second groove 33 (recess) on the vehicle outer side surface 30A. The first groove 32 and the second groove 33 extend along the airbag 11. Figure 5 As shown, one end (a portion) of the first groove 32 is continuous with the first connecting portion 51, and the first connecting portion 51 includes a notch 51D, and the first connecting portion 51 and the first groove 32 are connected by the notch 51D. The first fixing portion 41 includes a groove 41A (recess) on the outer side surface of the vehicle. The groove 41A is connected to the first groove 32.

[0036] like Figure 2 and Figure 3As shown, the second groove 33 is branched into two end portions 33A, 33B close to the reinforcing member 40. One end portion 33A of the second groove 33 extends to the first fixing portion 41, and the other end portion 33B extends to the second fixing portion 42. The end portion 33A of the second groove 33 is connected to a groove 41B (recess) formed in the vehicle outer side surface of the first fixing portion 41. The end portion 33B of the second groove 33 is connected to a groove 42A (recess) formed in the vehicle outer side surface of the second fixing portion 42.

[0037] like Figure 3 As shown, the first connection portion 51 and the second connection portion 52 are arranged along the longitudinal direction of the reinforcing member 40. The protruding portion 62 protrudes from the vehicle outer side surface of the second fixing portion 42 (one of a pair of fixing portions) toward the roof panel 10 (vehicle panel). The first connection portion 51 and the second connection portion 52 are arranged to sandwich the protruding portion 62. Figure 4 As shown, the protruding portion 62 has a box shape that opens downward and toward the inside of the vehicle. Figure 8 As shown, the protruding portion 62 has a protruding end surface 62A opposite to the roof panel 10 via the buffer member 72. The protruding portion 61 protrudes from the vehicle outer side surface of the first fixing portion 41 toward the roof panel 10. The protruding portion 61 has a box shape opened toward the inside of the vehicle. The protruding portion 61 has a protruding end surface 61A opposite to the roof panel 10 via the buffer member 71.

[0038] like Figure 2 As shown, the protruding portion 63 protrudes from the vehicle outer side surface of the second fixing portion 42 toward the roof panel 10. The protruding portion 63 is adjacent to the second connecting portion 52. Fig. 9 As shown, the protruding portion 63 has a Fig. 9 The protruding portion 63 has a protruding end surface 63A that is opposed to the roof panel 10 with the buffer member 73 interposed therebetween.

[0039] like Figure 2 As shown, the protruding portion 64 protrudes from the vehicle outer side surface of the third fixing portion 43 toward the roof panel 10. Fig.10 As shown, the protruding portion 64 has a Fig.10The plate member 30 is box-shaped and open (in the middle and downward). The protruding portion 64 has a protruding end surface 64A opposite to the roof panel 10 via a buffer member 74. The reinforcing member 40 includes protruding portions 61, 62, 63, 64. Therefore, when the plate member 30 is pressed toward the outside of the vehicle (toward the roof panel 10), the protruding end surfaces 61A, 62A, 63A, 64A of the protruding portions 61, 62, 63, 64 are in contact with the roof panel 10 via the buffer members 71, 72, 73, 74, respectively. According to this structure, the plate member 30 is not easily moved or deformed toward the outside of the vehicle. The buffer members 71, 72, 73, 74 are opposite to the roof panel 10 with a small gap, but can be in contact with the roof panel 10. The buffer members 71 , 72 , 73 , 74 may not be provided, and the protruding end surfaces 61A, 62A, 63A, 64A of the protruding portions 61 , 62 , 63 , 64 may be in direct contact with the roof panel 10 .

[0040] like Figure 3 As shown, the protrusion 45 protrudes from the vehicle outer side surface of the second fixing part 42 toward the roof panel 10. The protrusion 45 is continuous with the protrusion 61. The protrusion 45 has a box shape that is open toward the inside of the vehicle. The protrusion 45 has a protruding end surface and a through hole 45A in the protruding end surface. The protrusion 46 protrudes from the vehicle outer side surface of the second fixing part 42 toward the roof panel 10. The protrusion 46 is continuous with the protrusion 64. The protrusion 46 has a box shape that is open toward the inside of the vehicle. The protrusion 46 has a protruding end surface and a through hole 46A in the protruding end surface.

[0041] In order to join the reinforcing member 40 to the plate member 30, the tip portion of the positioning pin 95 (see Fig.10 46A) are inserted into the through holes 45A, 46A from the opposite side of the plate member 30. Therefore, the reinforcing member 40 is correctly positioned relative to the plate member 30. Then, by moving the positioning pin 95 toward the plate member 30, the reinforcing member 40 can be joined to the plate member 30 at the correct position. The through holes 45A, 46A in the protruding end surfaces of the protruding portions 45, 46 are away from the adhesive layer 31. Therefore, the distal end portions of the positioning pins 95 inserted into the through holes 45A, 46A do not contact the adhesive layer 31.

[0042] like Figure 2 , Figure 3 and Fig. 9 As shown, the first fixing portion 41, the second fixing portion 42 and the third fixing portion 43 each include ribs 81, 82. The ribs 81, 82 protrude from the outer side surface of the vehicle at the peripheral edge portion of the first fixing portion 41, the second fixing portion 42 and the third fixing portion 43 toward the outside of the vehicle. Figure 4As shown in FIG. 1 , ribs 83 and 84 are formed on the inner side surface of the second fixing portion 42. The ribs 83 and 84 are formed as a grid. Figure 3 As shown, the rib 85 protrudes from the vehicle outer side surface of the first fixing portion 41 toward the vehicle outer side. The rib 85 is formed as a grid and is continuous with the protruding portions 45, 61. Figure 4 As shown, the protruding portions 61, 62, 63, 64 include ribs 86, 87, 88, 89, respectively.

[0043] like Figure 2 As shown, the reinforcing member 40 includes ribs 90, 91, 92, 93. Rib 90 protrudes from the outer surface of the vehicle of the second fixing part 42. Rib 90 connects the protruding portion 63 and the second connecting portion 52. Ribs 91, 92 protrude from the outer surface of the vehicle of the third fixing part 43. Rib 91 connects the protruding portion 64 and the second connecting portion 52. Rib 92 connects the protruding portion 46 and the second connecting portion 52. Rib 93 protrudes from the outer surface of the vehicle of the second fixing part 42. Rib 93 is adjacent to the protruding portion 62 and is continuous with the protruding portion 62. By ribs 81 to 93, the rigidity of the reinforcing member 40 can be increased.

[0044] Next, the effect of this embodiment will be described. In this embodiment, the first fixing portion 41 and the second fixing portion 42 of the reinforcing member 40 are joined to the plate member 30. The first connecting portion 51 of the reinforcing member 40 connects the first fixing portion 41 and the second fixing portion 42. The first connecting portion 51 is not joined and does not contact the vehicle outer side surface 30A of the plate member 30. The first connecting portion 51 includes a middle portion 51A. The middle portion 51A is away from the vehicle outer side surface 30A. The first connecting portion 51 is U-shaped and extends from the first end portion 51B to the second end portion 51C in a manner bent away from the vehicle outer side surface 30A.

[0045] In the case of such a configuration, if the temperature of the reinforcing member 40 drops and the reinforcing member 40 contracts, the first connecting portion 51 expands or contracts along the longitudinal direction of the reinforcing member 40 to absorb the thermal contraction of the reinforcing member 40. Therefore, the first fixing portion 41 and the second fixing portion 42 joined to the plate member 30 can both move independently. In the case where the first fixing portion 41 and the second fixing portion 42 are connected by the first connecting portion 51, if the reinforcing member 40 contracts, the first fixing portion 41 and the second fixing portion 42 can move independently of each other. When the reinforcing member 40 joined to the plate member 30 contracts, the first connecting portion 51 connecting the first fixing portion 41 and the second fixing portion 42 is deformed so that the first end portion 51B and the second end portion 51C are away from each other. Therefore, the distance between the first fixing portion 41 and the second fixing portion 42 increases, and the reinforcing member 40 can absorb the thermal contraction. Therefore, the difference in the amount of contraction between the reinforcing member 40 and the plate member 30 can be absorbed by such deformation of the first connecting portion 51. Therefore, wrinkles are less likely to be generated on the plate member 30.

[0046] The reinforcing member 40 includes a first fixing portion 41 and a second fixing portion 42, each of which is separately joined to the plate member 30 and can be deformed separately. In the case of such a configuration, as the reinforcing member 40 contracts, a large stress is less likely to act locally on the plate member 30, and wrinkles are less likely to be generated on the plate member 30. In the case where the first fixing portion 41 and the second fixing portion 42 are connected by the first connecting portion 51, the reinforcing member 40 is configured as a single component and can be easily handled and the rigidity of the reinforcing member 40 is increased compared to a configuration including the first fixing portion 41 and the second fixing portion 42 as separate components. The second fixing portion 42 and the third fixing portion 43 connected by the second connecting portion 52 exert similar effects.

[0047] The plate member 30 includes a first groove 32 on the vehicle outer side surface 30A. The first groove 32 extends along the airbag 11 disposed on the vehicle outer side surface 30A adjacent to the reinforcement member 40. The first groove 32 is continuous with the first connecting portion 51. The first connecting portion 51 includes a notch 51D, and the first connecting portion 51 is connected to the first groove 32 through the notch 51D.

[0048] If the airbag 11 is activated, the plate member 30 is pushed by the inflated airbag 11 and bends along the first groove 32. Therefore, the airbag 11 can be smoothly inflated. In the case where the first connecting portion 51 is connected to the first groove 32 at the notch 51D, the plate member 30 can be smoothly bent along the first groove 32.

[0049] The first connection portion 51 and the second connection portion 52 are arranged along the longitudinal direction of the reinforcing member 40. By changing the arrangement of the first connection portion 51 and the second connection portion 52, the length of the second fixing portion 42 can be changed, and the degree of contraction of the second fixing portion 42 between the first connection portion 51 and the second connection portion 52 can be changed.

[0050] The second fixing portion 42 includes a protruding portion 62 protruding from the vehicle outer side surface toward the roof panel 10, in addition to the first fixing portion 41 and the second fixing portion 42. The first connecting portion 51 and the second connecting portion 52 are arranged to sandwich the protruding portion 62. If the plate member 30 is deformed or moved toward the roof panel 10, the protruding end surface 62A of the protruding portion 62 contacts the roof panel 10. Therefore, the plate member 30 is less likely to move further toward the roof panel 10. This increases the rigidity of the plate member 30.

[0051] The groove 41A is formed on the vehicle outer side surface of the first fixing portion 41 and is connected to the first groove 32. The groove 41B is formed on the vehicle outer side surface of the first fixing portion 41 and is connected to the end portion 33A of the second groove 33. The groove 42A is formed on the vehicle outer side surface of the second fixing portion 42 and is connected to the end portion 33B of the second groove 33. With the grooves 41A, 41B, 42A, when the airbag 11 is inflated, the bending of the plate member 30 is less likely to be hindered by the reinforcing member 40.
