Description

  The present invention relates to a mounting structure for a ceiling interior material.

  A ceiling interior material is attached to a vehicle interior side of an exterior panel (for example, a roof panel or a roof side rail) that constitutes a vehicle body in a vehicle. Various equipment such as cushioning materials and curtain shield airbags are stored between the exterior panel and the ceiling interior material. For this reason, the exterior panel and the ceiling interior material are greatly separated from each other, and when the ceiling interior material is pressed from the vehicle interior side, the ceiling interior material is recessed upward, which affects the product quality of the vehicle. End up. Therefore, a technique is known in which a separate spacer member is disposed between the exterior panel and the ceiling interior material in order to prevent the ceiling interior material from being recessed upward. As a similar technique, the following Patent Document 1 discloses a vehicle that can prevent the pillar garnish from being recessed when the pillar garnish is pressed from the vehicle interior side in the vicinity of the boundary between the ceiling of the vehicle and the pillar garnish. A terminal processing structure for a ceiling is disclosed.

  FIG. 13 shows an example of a conventional mounting structure 120 for the ceiling interior material 104 in which the spacer member 110 is disposed between the exterior panel 112 and the ceiling interior material 104. FIG. 13 is a cross-sectional view showing the mounting structure 120 for the ceiling interior material 104, and reference numerals 104, 110, 112, and 114 indicate the ceiling interior material, the spacer member, the inner panel (exterior panel), and the opening trim, respectively. . In the mounting structure 120, the spacer member 110 is provided with a locking portion 110a and a contact portion 110c. The locking part 110a is locked to the exterior panel 112, whereby the spacer member 110 is fixed. The contact portion 110 c is in contact with the terminal portion 104 a of the ceiling interior material 104. According to such a configuration, when the ceiling interior material 104 is pressed from the vehicle interior side, the contact portion 110c acts as a power point with the locking portion 110a as a fulcrum, and the ceiling interior material 104 is moved upward by the rigidity of the spacer member 110. Indentation is prevented.

JP 2003-291743 A

  However, in the conventional mounting structure 120 described above, since the distance between the contact portion 110c and the locking portion 110a is long, the spacer member 110 can withstand the load when a large load is applied to the spacer member 110. May not be able to bend and bend. As a result, a gap may be formed between the ceiling interior material 104 and the opening trim 114, and the appearance quality is deteriorated.

  The present invention has been created in view of the above problems. The present invention provides a ceiling interior material mounting structure that prevents the ceiling interior material from being recessed and maintains the appearance quality even when the ceiling interior material is pressed from the vehicle interior side with a large load. The purpose is to provide.

  In the technology disclosed in this specification, a ceiling interior material is attached to a vehicle interior side of an exterior panel constituting a vehicle body, and a spacer member is disposed between the exterior panel and the ceiling interior material. In the interior material mounting structure, the spacer member abuts against an exterior surface of the ceiling interior material and an engaging portion for securing the spacer member to the exterior exterior panel by being engaged with the exterior panel. An abutting portion that is in contact with each other, and the abutting portion transmits a load received from the ceiling interior material to the exterior panel between the abutting portion and the locking portion of the spacer member. The present invention relates to a mounting structure for a ceiling interior material provided with a restriction portion that comes into contact with the exterior panel.

  According to the above mounting structure, since the restriction portion is provided between the contact portion and the locking portion, when the spacer member receives a load from the ceiling interior material, the contact portion is used as a power point. Can act as a fulcrum. When the restricting portion is acted as a fulcrum, the distance between the force point and the fulcrum is shorter than when the locking portion is acted as a fulcrum, so that the deflection displacement at the force point can be suppressed. For this reason, even when a large load is applied to the ceiling interior material, the bending of the spacer member is restricted, and the generation of a gap between the terminal portion of the ceiling interior material and the opening trim can be suppressed.

The exterior panel may have a projecting portion that projects toward the spacer member, and the upper surface side of the restricting portion of the spacer member may contact the lower surface side of the projecting portion of the exterior panel.
According to this configuration, the displacement of the spacer member can be more suitably regulated using the protrusion provided on the exterior panel.

In the spacer member, a distance between the restriction portion and the contact portion may be shorter than a distance between the restriction portion and the locking portion.
According to this configuration, when a load is applied to the ceiling interior material, the distance between the force point and the fulcrum in the spacer member can be further shortened, and the occurrence of bending in the ceiling interior material is effectively regulated. Can do.

  According to the technique disclosed in this specification, in the ceiling interior material mounting structure, even when the ceiling interior material is pressed with a large load from the vehicle interior side, the ceiling interior material is prevented from being recessed, Appearance quality can be maintained.

<Embodiment 1>
Embodiment 1 will be described with reference to the drawings. FIG. 1 is a side view illustrating an outline of a passenger compartment of a vehicle 2 according to the first embodiment. As shown in FIG. 1, a pair of side windows 8, 8 are arranged on the side of the vehicle 2. Pillar garnishes 6 are disposed on the front side of the side window 8 on the front side of the vehicle, between the side windows 8 and 8, and on the rear side of the side window 8 on the rear side of the vehicle. On the other hand, as shown in FIG. 3, a ceiling interior material 4 is disposed facing the vehicle interior side of an inner panel (an example of an exterior panel) 12 constituting an outer plate (vehicle body) of the vehicle 2. In the following description, the inside in the vehicle width direction (the left side in the drawing in FIG. 3) is referred to as the inside, and the outside in the vehicle width direction (the right side in the drawing in FIG. 3) is referred to as the outside.

  In FIG. 2, the side view which expanded a part of ceiling part of the vehicle 2 is shown. FIG. 2 is an enlarged side view of the inside of the alternate long and short dash line portion X in FIG. 1 and shows the upper side of the pillar garnish 6 positioned between the side windows 8 and 8. The broken line in FIG. 2 indicates the spacer member 10. As shown in FIG. 3, the spacer member 10 is disposed between the ceiling interior material 4 and the inner panel 12. A space is formed between the ceiling interior material 4 and the spacer member 10, and a curtain shield airbag or the like is accommodated in this space.

  The inner panel 12 is provided with a mounting hole 12a and a protruding portion 12b. The attachment hole 12a is provided in a form penetrating the inner panel 12. The protruding portion 12b is provided below the mounting hole 12a, and is provided in a form that bulges to the vehicle interior side. Note that a roof side rail (not shown) is configured by the inner panel 12 and an outer panel (not shown) arranged outside the inner panel 12. This roof side rail constitutes the side part of the ceiling part of the vehicle 2.

  The ceiling interior material 4 is obtained by attaching a skin material 18 to the surface of a sheet-like base material 16. The substrate 16 is made of a flexible material such as urethane foam. The skin material 18 is made of, for example, a woven fabric, a nonwoven fabric, a resin sheet, or leather. The ceiling interior material 4 may be referred to by another name such as “roofing” or “formed ceiling”.

  As shown in FIG. 4, the spacer member 10 has a substantially gate shape as a whole by connecting the ends of a pair of spacer bodies 11a, 11a with a connecting portion 11b. And as shown in FIG. 5, the latching | locking part 10a, the control part 10b, and the contact part 10c are provided in the back side of the spacer main body 11a of the spacer member 10 from the connection part 11b side. In addition, the spacer member 10 shown in FIG. 4 is a member integrally formed of a resin material such as polypropylene.

  The locking part 10a has a pair of elastic pieces 10a1. When this locking portion 10a is inserted into the mounting hole 12a provided in the inner panel 12, both elastic pieces 10a1 are elastically locked from the outside of the passenger compartment to the hole edge of the mounting hole 12a. The spacer member 10 is fixed to the vehicle interior side of the inner panel 12. The abutting portion 10 c is bent along the terminal portion 4 a of the ceiling interior material 4, and abuts on the vehicle interior side surface of the terminal portion 4 a of the ceiling interior material 4.

  As shown in FIG. 5, on the back side of the spacer main body 11a, an outer peripheral rib 11c rising along the outer peripheral edge of the spacer main body 11a and a reinforcing rib 11d extending in the longitudinal direction at the center in the width direction of the spacer main body 11a are provided. ing. The restricting portion 10b is provided below the reinforcing rib 11d and is not provided below the outer peripheral rib 11c. In this case, for example, when the regulating portion 10b is punched from the molding die in the molding process of the spacer member 10, the contact range between the regulating portion 10b and the molding die is small, so that the die can be easily cut. Therefore, the spacer member 10 can be easily formed.

  Now, as shown in FIG. 3, the vehicle interior side surface of the terminal portion 4 a of the ceiling interior material 4 is in contact with a part of the opening trim 14 disposed on the outside of the ceiling interior material 4. The opening trim 14 is made of an elastic material such as rubber, and is fitted into and attached to a flange portion (not shown) that projects from the roof side rail.

  Here, the restricting portion 10b is provided between the locking portion 10a and the abutting portion 10c, and protrudes toward the outside of the passenger compartment. The upper surface side of the restricting portion 10b is in contact with the lower surface side of the protruding portion 12b of the inner panel 12, thereby restricting the spacer member 10 from moving upward. Note that the distance W2 between the restricting portion 10b and the contact portion 10c is shorter than the distance W1 between the restricting portion 10b and the locking portion 10a.

  According to such an attachment structure 20, when the ceiling interior material 4 is pressed from the vehicle interior side, a load is applied to the spacer member 10 via the contact portion 10c. Here, the load applied to the spacer member 10 is transmitted upward from the contact portion 10c (the direction from the contact portion 10c to the locking portion 10a), but between the contact portion 10c and the locking portion 10a. Since the restricting portion 10b is provided, most of the load is concentrated on the restricting portion 10b. However, since the distance from the restricting portion 10b to the abutting portion 10c is short, the deflection displacement amount of the abutting portion 10c can be suppressed when the abutting portion 10c acts as a power point with the restricting portion 10b serving as a fulcrum. For this reason, the lifting of the terminal portion 4a of the ceiling interior material 4 is restricted, and the formation of a gap between the terminal portion 4a of the ceiling interior material 4 and the opening trim 14 can be restricted.

  As described above, in the mounting structure 20 for the ceiling interior material 4 according to the present embodiment, the spacer member 10 is made to be the ceiling interior material by providing the restricting portion 10b between the contact portion 10c and the locking portion 10a. When receiving a load from 4, the contact portion 10c can be used as a force point and the restricting portion 10b can be used as a fulcrum. When the restricting portion 10b is acted as a fulcrum, the distance between the force point and the fulcrum is shorter than when the locking portion 10a is acted as a fulcrum, so that bending displacement at the force point can be suppressed. For this reason, even if a large load is applied to the ceiling interior material 4, the bending of the spacer member 10 is restricted, and a gap is generated between the terminal portion 4 a of the ceiling interior material 4 and the opening trim 14. The appearance quality can be maintained.

  Moreover, in said embodiment, the inner panel 12 has the protrusion part 12b which protrudes toward the spacer member 10, the upper surface side of the control part 10b of the spacer member 10, and the lower surface side of the protrusion part 12b of the inner panel 12 Are in contact. For this reason, the displacement of the spacer member 10 can be more suitably regulated by using the protruding portion 12 b provided on the inner panel 12.

  Moreover, in said embodiment, in the spacer member 10, the distance W2 between the control part 10b and the contact part 10c is shorter than the distance W1 between the control part 10b and the latching | locking part 10a. For this reason, when a load is applied to the ceiling interior material 4, the distance between the force point (contact portion 10 c) and the fulcrum (regulation portion 10 b) in the spacer member 10 can be further shortened. The deflection displacement can be effectively controlled.

<Embodiment 2>

For this reason, in the spacer member 30, as shown in FIGS. 8 and 9, the number of the restricting portions 30b is larger than the configuration in which the restricting portions 30b are provided only at the lower portion of the reinforcing rib 31d. When the number of the restricting portions 30b is large, when a load is applied to the restricting portions 30b, the load is distributed to the restricting portions 30b. For this reason, in the spacer member 30, even when a large load is applied to the ceiling interior material 4, the bending of the spacer member 30 is restricted, and a gap is formed between the terminal portion 4 a of the ceiling interior material 4 and the opening trim 14. Can be effectively suppressed.

FIG.

  In the spacer member 50, as shown in FIG. 10, the restricting portion 50b is provided below the outer peripheral rib 51c on the back side of the spacer body 51a, and is not provided below the reinforcing rib 51d. Even in such a configuration, when a large load is applied to the ceiling interior material 4, the bending of the spacer member 10 is restricted, and a gap is generated between the terminal portion 4 a of the ceiling interior material 4 and the opening trim 14. Can be suppressed.
