With reference to FIG. 1, the mounting structure of vehicle interior parts according to the present embodiment includes an instrument panel 10, a side panel 30, and a side register 40.

The instrument panel 10 is a design panel (interior panel) provided in front of the vehicle interior, and houses an instrument such as a speedometer, an air conditioner, and the like. The instrument panel 10 is composed of a resin panel having a three-layer structure in which a foam material such as urethane is laminated on a resin molded panel, and a skin layer constituting the design surface is further laminated.

Although the instrument panel 10 has a complicated three-dimensional shape, it includes an upper wall portion 12 and a rear wall portion 14 as its main components. The upper wall portion 12 faces the vehicle height direction. The upper wall portion 12 may have a curved surface shape, and "facing in the vehicle height direction" means, for example, when the normal vector of the wall surface is decomposed into three axes of UP axis, FR axis, and LH axis. Includes that the component of the UP axis has the highest value. For example, in the upper wall portion 12, a slit 11 which is an outlet of the wind defroster is formed at the front end thereof in the vehicle width direction.

The rear wall portion 14 is a rear end member of the instrument panel 10, is connected to the rear end of the upper wall portion 12, and faces the vehicle in the front-rear direction. Similar to the upper wall portion 12, the rear wall portion 14 may have a curved surface shape. The phrase "facing in the front-rear direction of the vehicle" includes, for example, that the component of the FR axis has the highest value when the normal vector of the wall surface is decomposed into three axes of the UP axis, the FR axis, and the LH axis. ..

In the space in front of the passenger compartment, which is surrounded by the upper wall portion 12 and the rear wall portion 14, the air-conditioning equipment, the steering equipment, and the instrument panel lean force (instrument panel R) which is a skeleton member supporting these equipments. / F) is accommodated.

The rear wall portion 14 is arranged so as to face the occupant in the passenger seat or the driver's seat. A mounting opening 20 (see FIG. 3) is formed in the rear wall portion 14 so as to penetrate in the wall thickness direction and arrange the side register 40. The mounting opening 20 is provided in the vehicle width direction side portion of the rear wall portion 14, and is a notch hole in which the vehicle width direction side end is opened. As illustrated in FIG. 1, the side register 40 is arranged so as to be sandwiched between the vehicle width direction side end of the rear wall portion 14 and the side panel 30. With reference to FIG. 2, the opening shaft L1 of the mounting opening 20 is provided along (for example, in parallel) the vehicle front-rear direction (FR axis direction).

With reference to FIG. 2, the rear wall portion 14 includes an exposed surface 14A and a hidden surface 14B. The exposed surface 14A is a surface exposed in the vehicle interior and corresponds to the rear surface of the rear wall portion 14. The hidden surface 14B is a facing surface (back surface) of the exposed surface 14A and is not exposed inside the vehicle interior. The hidden surface 14B hits the front surface of the rear wall portion 14.

With reference to FIGS. 2 and 3, the hidden surface 14B of the rear wall portion 14 is provided with an arm 16 projecting from the hidden surface 14B. The arm 16 is a plate member extending, for example, vertically from the hidden surface 14B, that is, in front of the vehicle. A panel-side locking hole 18 is drilled in the arm 16 in the vehicle width direction. As will be described later, the register-side locking claw 48 of the side register 40 is inserted and locked in the panel-side locking hole 18.

The arm 16 is provided on the hidden surface 14B at the periphery of the mounting opening 20. For example, the arm 16 is provided so as to project within 10 cm from the edge that partitions the mounting opening 20.

With reference to FIG. 1, the side panel 30 is provided laterally in the vehicle width direction and faces the vehicle width direction. The side panel 30 may have a curved surface shape. The phrase "facing in the vehicle width direction" includes, for example, that the component of the LH axis has the highest value when the normal vector of the wall surface is decomposed into three axes of the UP axis, the FR axis, and the LH axis. .. Further, the rear end portion of the side panel 30 may be bent inward in the vehicle width direction.

The side panel 30 abuts on the vehicle width direction side ends of the upper wall portion 12 and the rear wall portion 14 of the instrument panel 10 and covers the space surrounded by the upper wall portion 12 and the rear wall portion 14 from the side. .. With reference to FIG. 2, the side panel 30 includes an exposed surface 30A and a hidden surface 30B. The exposed surface 30A is a design surface exposed to the vehicle interior. The hidden surface 30B is a facing surface (back surface) of the exposed surface 30A, is surrounded by the upper wall portion 12 and the rear wall portion 14 of the instrument panel 10, and is not exposed to the vehicle interior.

The hidden surface 30B of the side panel 30 is provided with a panel-side locking claw 32 extending in the vehicle width direction from the hidden surface 30B. The panel-side locking claw 32 is provided on the hidden surface 30B at a portion facing the side register 40.

With reference to FIG. 1, the side register 40 is an air volume adjusting component provided at an outlet of an air conditioner for a passenger compartment. The side register 40 is attached to the rear wall portion 14 of the instrument panel 10. An outlet 42 is provided on the rear surface of the side register 40, that is, the surface exposed to the vehicle interior. The outlet 42 is provided with an air volume adjusting mechanism (not shown).

With reference to FIG. 3, the front end of the side register 40 is connected to a duct of an air conditioner (not shown). Further, a substantially square cylindrical casing 41 is provided between the front end (duct connection portion) and the rear end (outlet 42) of the side register 40.

With reference to FIGS. 2 and 3, a register-side locking claw 48 is extended inward in the vehicle width direction on the inner side surface 44 of the casing 41 of the side register 40 in the vehicle width direction. Further, a register-side locking hole 52 is formed in the outer surface 46 of the casing 41 in the vehicle width direction in the vehicle width direction. In the examples of FIGS. 2 and 3, the register-side locking hole 52 is indirectly drilled in the outer surface 46 in the vehicle width direction via the arm 50.

In the following, the inner side surface 44 in the vehicle width direction is simply referred to as the inner side surface 44, and the outer side surface 46 in the vehicle width direction is simply referred to as the outer side surface 46. In short, when the side register 40 is attached to the mounting opening 20 (see FIG. 3), the side surface of the casing 41 that is relatively inside in the vehicle width direction becomes the inner side surface 44, and the casing 41 that is relatively outside in the vehicle width direction. The side surface of is the outer surface 46.

With reference to FIGS. 2 and 3, the arm 50 extends outward in the vehicle width direction from the outer surface 46 of the casing 41 and extends in front of the vehicle in a state of being separated from the outer surface 46 in the vehicle width direction. It is a plate member to be made. Further, a register-side locking hole 52 is drilled in the front end portion of the arm 50 in the vehicle width direction.

With reference to FIG. 2, when the side register 40 is mounted in the mounting opening 20, the register-side locking claw 48 is inserted and locked in the panel-side locking hole 18, and the panel-side locking claw 48 is inserted in the register-side locking hole 52. 32 is inserted and locked. As described above, the register-side locking claw 48 and the panel-side locking claw 32 are extended in the direction orthogonal to the opening axis L1.

Further, the arm 50 into which the panel-side locking claw 32 is inserted and the register-side locking claw 48 extend to the outside of the mounting opening 20. By providing such a structure, when a load generated in the vehicle front-rear direction, particularly at the time of a vehicle rear collision, is applied to the side register 40, the register side locking claw 48 and the arm 50 become caught. , The side register 40 is suppressed from falling out from the mounting opening 20.

In other words, in the mounting structure of the vehicle interior component according to the present embodiment, in addition to the elastic force of the locking claw locked in the locking hole of the side register 40, the register side locking protruding outward from the mounting opening 20. By catching the claw 48 and the arm 50 on the frame of the mounting opening 20, the side register 40 is prevented from falling out of the mounting opening 20.

Further, the instrument panel 10 has a so-called horizontally long structure in which the dimension in the vehicle width direction is longer than the dimension in the vehicle front-rear direction. Since the extension direction of the register-side locking claw 48 is along the longitudinal direction of the instrument panel 10, the restriction on the extension length of the register-side locking claw 48 extends in the lateral direction of the instrument panel 10. It will be looser than when it is installed. Therefore, for example, the register-side locking claw 48 can be extended to a region separated from the mounting opening 20. As described above, by increasing the hooking length with respect to the mounting opening 20, the side register 40 can be more effectively suppressed from falling out of the mounting opening 20.

For example, an airbag (not shown) is provided in the instrument panel 10, and the instrument panel 10 is deformed when the airbag is deployed. Due to this deformation, the opening shape of the mounting opening 20 is also deformed. In the mounting structure of the vehicle interior parts according to the present embodiment, the fitting allowance b (hooking length) of the register-side locking claw 48 to the panel-side locking hole 18 may be longer than that of the conventional structure. Therefore, even when the mounting opening 20 is deformed, the side register 40 is effectively suppressed from coming off from the mounting opening 20.

For example, FIG. 4 illustrates an instrument panel 100 and a side register 140 according to a conventional structure. In this example, the side register 140 is locked to the instrument panel 100 in the vehicle front-rear direction. More specifically, the side register 140 is provided with a locking claw 132. The locking claw 132 includes a shaft 132A extending in the front-rear direction of the vehicle and a hook 132B provided at the tip thereof and protruding in the vehicle width direction. Further, the instrument panel 100 is provided with a protrusion 102 that protrudes in the vehicle width direction and engages with the hook 132B of the locking claw 132 on the side wall 101 extending in the vehicle front-rear direction.

In such a case, the fitting allowance a of the locking claw 132 to the protrusion 102 is limited by the overhang length of the hook 132B of the locking claw 132. On the other hand, as illustrated in FIG. 2, in the mounting structure of the vehicle interior component according to the present embodiment, the fitting allowance b (hook length) of the register-side locking claw 48 to the panel-side locking hole 18 ) Is the length of the shaft 48A of the register-side locking claw 48, so that it can be taken longer than the fitting allowance a of the conventional structure. Similarly, the fitting allowance c (hooking length) of the panel-side locking claw 32 to the register-side locking hole 52 is also the length of the shaft 32A of the panel-side locking claw 32, so that the conventional structure is fitted. It can be taken longer than the generation a. Therefore, even when the mounting opening 20 is deformed, the side register 40 is effectively suppressed from falling out of the mounting opening 20.

Further, when the airbag is deployed, not only the instrument panel 10 but also the side register 40 is deformed. In the side register 40 according to the present embodiment, deformation is suppressed as compared with the conventional structure.

For example, with reference to FIG. 4, the conventional side register 140 is flexed and deformed as shown by the dashed line when the airbag is deployed or on a rough road, and as a result, the duct is shown by the dashed arrow. Air-conditioned air may leak out of the duct 110 at the connection point with the 110. On the other hand, the side register 40 illustrated in FIG. 2 is suppressed from bending and deforming by the casing 41 extending in the front-rear direction of the vehicle. Further, since the amount of deformation of the side register 40 is smaller than that of the conventional structure, the deformation at the time of assembly is also small, and the so-called installability is improved.

In FIGS. 2 and 3, a set of the panel-side locking hole 18 and the register-side locking claw 48, and a set of the register-side locking hole 52 and the panel-side locking claw 32 are shown one by one. However, at least two or more sets may be provided, and the support points of the side register 40 with the instrument panel 10 and the side panel 30 may be three or more points.

When the side register 40 has two support points, the side register 40 may rotate (rotate) with the line connecting these two points as the axis of rotation. However, by setting the support points to three or more points, Such rotation can be suppressed.

<Assembly process of mounting structure of vehicle interior parts>
The assembly process of the mounting structure of the vehicle interior parts according to the present embodiment will be described with reference to FIG. As described above, the mounting opening 20 of the instrument panel 10 is a notch hole with an open end on the vehicle width direction side. When the side register 40 including the register-side locking claw 48 and the arm 50 projecting in the vehicle width direction is attached to the mounting opening 20, the side register 40 is fitted to the side in the vehicle width direction from the open portion of the mounting opening 20. At this time, the register-side locking claw 48 is inserted into and locked in the panel-side locking hole 18 of the instrument panel 10.

When the side register 40 is housed in the mounting opening 20, the side panel 30 is urged from the outside to the inside in the vehicle width direction so as to close the side end of the instrument panel 10.
