When the deformation of the instrument panel main body 105 further proceeds, the demister grill 103 is bent in the front-rear direction and the rear side rises, and is scattered to the rear side by a reaction force as shown in FIG. .

  This invention is made | formed in view of this point, The place made into the objective is to prevent that vehicle interior components are scattered from a to-be-attached member, and hit a passenger | crew.

  In order to achieve the above object, the present invention devises the structure around the engagement hole.

  Specifically, the present invention is directed to a mounting structure in which a resin vehicle interior part is fitted into a fitting hole formed in a resin mounted member and the interior part is attached to the mounted member. The following solutions were taken.

According to a first aspect of the present invention, an engagement piece protrudes toward the rear side on the occupant side outer peripheral edge of the interior part, and the engagement piece is formed on the occupant side outer periphery of the fitting hole of the attached member. Engagement holes are formed, and a pair of slits or a pair of planned break lines are formed at intervals in the width direction of the engagement pieces around the occupant side outer periphery of the engagement holes. When the occupant collides in front of the fitting hole of the mounted member between a pair of slits or a pair of planned break lines , an impact that absorbs an impact load by abutting and deforming the engaging piece The absorption part is comprised .

According to a second aspect of the present invention, in the first aspect of the present invention, the engaging piece is formed with a locking claw that engages with the outer periphery of the occupant side of the engaging hole, and the outer rim on the side opposite to the occupant of the interior part Is characterized in that an engagement piece that engages with the outer periphery of the fitting hole on the side opposite to the occupant protrudes toward the back side.

According to a third aspect of the present invention, in the first aspect of the present invention, an engagement piece formed with a locking claw is provided projecting toward the rear side on the outer occupant side outer periphery of the interior part. An engagement hole on the side opposite to the occupant is formed on the outer periphery of the fitting hole on the side opposite to the occupant to which the engagement piece formed with the locking claw is engaged.

In a fourth aspect based on the third aspect , a standing wall portion that restricts movement of the interior part toward the anti-occupant side is provided on the counter-occupant side outer periphery of the engagement hole on the counter-occupant side in the attached member. Is projected.

According to a fifth invention, in the third or fourth invention, the shock absorbing portion is provided on an outer side of the counter occupant side of the engagement hole on the counter occupant side of the attached member. And

  According to the first invention, when the occupant collides in front of the fitting hole of the mounted member, the shock absorbing portion provided around the occupant side of the engagement hole contacts the engagement piece and deforms. Thus, since the impact load is absorbed, the outer periphery on the passenger side of the engagement hole does not collide with the engagement piece, and the engagement piece can be prevented from breaking. Therefore, since the engagement state between the interior part and the attached member is maintained at the time of a passenger collision, scattering of the interior part can be prevented.

Moreover , since the shock absorbing part is provided between the pair of slits, it is easy to bend. Therefore, even when the engagement piece hits the impact absorbing portion when the engagement piece is inserted into the engagement hole, the impact absorbing portion bends, so the engagement piece is inserted into the engagement hole with a relatively small force. be able to.

According to the second aspect of the present invention, the engagement piece that engages with the outer periphery of the fitting hole on the non-occupant side is provided on the back surface of the interior component on the non-occupant side. In other words, since the interior parts are provided with engagement pieces that engage with the mounted members on both the occupant side and the counter occupant side, the interior parts are covered at both ends of the interior part on the occupant side and the counter occupant side. It can be engaged with the mounting member. Therefore, it is possible to more reliably prevent the interior parts from scattering. Further, since the engagement piece on the occupant side is formed with a locking claw that locks with the outer periphery of the engagement hole, the engagement state with the attached member becomes stronger. Therefore, it is possible to more reliably prevent the interior parts from scattering.

According to the third invention, when the occupant collides before the fitting hole of the mounted member, the locking claw provided on the engagement piece on the non-occupant side is on the outer periphery of the engagement hole on the anti-occupant side. Since it is locked, it is possible to prevent the non-occupant side engaging piece from being disengaged from the anti-occupant side engaging hole. Therefore, it is possible to more reliably prevent the interior parts from scattering from the attached member.

According to the fourth invention, when the occupant collides before the fitting hole of the mounted member, the engagement piece on the side opposite to the occupant is pushed to the side opposite to the occupant and the outer periphery of the engagement hole on the side opposite to the occupant Although it deform | transforms so that it may contact | abut and incline, when the interior component contact | abuts to a standing wall part, the movement to the passenger | crew side of this interior component is controlled. Then, the movement of the engagement piece on the side opposite to the occupant to the side opposite to the occupant is also restricted, and deformation of the engagement piece is also suppressed. Therefore, the engagement piece can be prevented from being broken and broken. Thereby, the state which the said engagement piece engages with the said engagement hole by the side of a passenger | crew is hold | maintained, and it can prevent more reliably that a built-in component scatters from a to-be-attached member.

According to the fifth aspect of the present invention, when the occupant collides before the fitting hole of the mounted member, an impact load that acts on the engagement piece on the non-occupant side is provided around the engagement hole on the anti-occupant side. Since it is absorbed by the impact absorbing portion, it can be prevented that the engagement piece on the side opposite to the passenger contacts the outer periphery of the engagement hole and breaks.

The vent grill 11 has four movable fins 11a, and adjusts the wind direction of the conditioned air generated by the air conditioner and blown out to the passenger compartment R with the movable fins 11a.

  On the other hand, a resin-made differential duct 17 that guides conditioned air of the air conditioner to the side demister air outlet 3 is provided below the upper surface portion 13d of the panel body 13, and the differential duct 17 is welded to the rear surface of the upper surface portion 13d. ing. A substantially triangular resin demister grill 9 corresponding to the shape is attached to the side demister air outlet 3. This demister grill 9 has five fixed fins 9a, and these fixed fins 9a are inclined so as to blow out conditioned air generated by the air conditioner to a side glass (not shown).

  FIG. 4 is a perspective view before the demister grill 9 is attached to the instrument panel 1. FIG. 5 is an overall perspective view of the demister grill 9. The demister grill 9 is an injection molded product made of a resin such as polypropylene. The demister grill 9 has a substantially triangular frame-shaped grill frame 9b. The grill frame 9b includes a frame main body 9c in which the five fixing fins 9a are integrally provided, and an upper end of the frame main body 9c. It is comprised by the collar part 9d projected outside from. Engagement pieces 9e and 9f are projected from the front and rear ends of the frame main body 9c, respectively, toward the back side. The engagement piece 9e provided at the front end (hereinafter referred to as a front end engagement piece) 9e has a flat plate shape that is inclined downward toward the front. The engagement piece 9f provided at the rear end (hereinafter referred to as a rear end engagement piece) 9f includes a rectangular frame-like engagement piece outer frame 9g extending vertically downward from the rear surface of the frame main body 9c, and an outside of the engagement piece. The frame 9g has a substantially pyramid-shaped locking claw 9h extending upward from the center of the lower end of the frame 9g and protruding rearward. The engagement piece outer frame 9g is provided on the upper side and both sides in the vehicle width direction of the locking claw 9h. A gap 9j is formed between the two. The locking claw 9h can bend in the longitudinal direction of the vehicle body inside the engagement piece outer frame 9g.

  The outer periphery of the front end of the side demister air outlet 3 is sandwiched by the front end portion of the frame body 9c and the front end engaging piece 9e from above and below. On the other hand, the rear end engagement piece 9f is engaged with a rear engagement hole 19 formed around the rear outer periphery of the side demister air outlet 3. FIG. 6 is a perspective view of the side demister air outlet 3 as viewed from the rear side, that is, from the passenger side. As shown in FIG. 6, the rear engagement hole 19 has a rectangular shape that is long in the longitudinal direction of the vehicle body, and the vehicle width direction dimension is slightly larger than the width of the rear end engagement piece 9f. The rear outer periphery of the rear engagement hole 19 is not covered with the skin 13b and the foam layer 13c, and the base material 13a is exposed. A pair of slits 19a are formed on the outer periphery of the rear side so as to be spaced apart in the vehicle width direction. A horizontal rectangular plate-shaped shock absorbing portion 21 extending forward of the vehicle body is formed between the slits 19a. Is formed. When an impact load in the longitudinal direction of the vehicle body is applied to the impact absorbing portion 21, the impact absorbing portion 21 is bent to absorb the impact load. Since the shock absorbing portion 21 is formed between the slits 19a and is cantilevered, it is easily bent in the vertical direction. Therefore, even when the rear end engaging piece 9f is inserted into the rear side engaging hole 19, even if it hits the shock absorbing part 21, the shock absorbing part 21 bends. Therefore, the rear end engaging piece 9f is moved to the rear side engaging hole. 19 can be inserted with a relatively small force. The outer periphery of the impact absorbing portion 21 and the rear engagement hole 19 is preferably formed to be thin so as to absorb the impact load more efficiently.

  When attaching the demister grill 9 to the side demister air outlet 3, first, the front end engaging piece 9 e is inserted into the front end of the side demister air outlet 3, and then the rear end engaging piece 9 f is connected to the side demister air outlet 3. The rear end of the demister grill 9 is pushed downward by being inserted into the rear engagement hole 19. Then, the outer periphery of the front end of the side demister air outlet 3 is sandwiched from the upper and lower sides by the front end of the frame body 9c and the front end engaging piece 9e of the demister grill 9, and further, the locking claw 9h of the rear end engaging piece 9f. The demister grill 9 is fitted to the side demister air outlet 3 by locking around the outer periphery of the rear engagement hole 19.

On the other hand, the relatively rigid demister grill 9 is difficult to bend and its shape is maintained. The front end contacts the rear end engaging piece 9f. When the rear end of the upper surface portion 13d is further pushed forward, the rear end of the upper surface portion 13d is compressed forward and curved upward as shown in FIG. 7, and the shock absorbing portion 21 is moved to the rear end engaging piece 9f. The impact load is absorbed by bending so as to protrude upward. As a result, the outer periphery of the rear engagement hole 19 does not collide with the rear end engagement piece 9f, and the rear end engagement piece 9f can be prevented from breaking. Therefore, since the state in which the locking claw 9h is locked around the outer periphery of the rear side engagement hole 19 is maintained, the rear end engagement piece 9f can be prevented from being detached from the rear side engagement hole 19. Furthermore, the shock absorbing portion 21 presses the rear end engaging piece 9k downward in a bent state. Therefore, it is possible to more reliably prevent the rear end engaging piece 9k from being detached from the rear side engaging hole 19.

  In this way, even if the occupant A collides with the instrument panel 1 from the rear, the engagement state between the demister grill 9 and the instrument panel 1 is maintained, so that the demister grill 9 is prevented from scattering. Can do. Therefore, the passenger | crew A can be protected.

(Third embodiment)
In the said 2nd Embodiment, although the impact-absorbing part 21 was provided in the outer periphery back side of the side demister air blower outlet 3, you may provide in the front and back both sides. FIG. 10 is a view corresponding to FIG. 8A of the instrument panel 1 to which the demister grill 9 is attached by the vehicle interior part mounting structure according to the present embodiment. The configuration other than the outer periphery of the front engagement hole 23 is the same as that of the second embodiment, and the same portions are denoted by the same reference numerals and the description thereof is omitted.

  The front outer periphery of the front engagement hole 23 is not covered with the skin 13b and the foam layer 13c, and the base material 13a is exposed. A pair of slits (not shown) are formed around the front outer periphery of the front engagement hole 23 with an interval in the vehicle width direction, and a horizontal rectangular plate-like shock absorbing portion 27 extending rearward of the vehicle body is formed between the two slits. Is formed. When an impact load in the longitudinal direction of the vehicle body is applied to the impact absorbing portion 27, the impact load is absorbed by the bending of the impact absorbing portion 27. In addition, the standing wall part 13e of the said 2nd Embodiment is not formed. Further, the outer peripheries of the shock absorbing portion 27 and the front engagement hole 23 are formed relatively thin.

  In the demister grill 9, the rear end engagement piece 9 k is inserted into the rear side engagement hole 19 and applied to the shock absorbing portion 21 from below, while the front end engagement piece 9 m is inserted into the front side engagement hole 23.

When the front end engaging piece 9m is further pushed, the impact absorbing portion 27 having a relatively low rigidity is bent so as to protrude upward while losing the front end engaging piece 9m. Thereby, the outer periphery of the front side engagement hole 23 does not collide with the front end engagement piece 9m, and the front end engagement piece 9m can be prevented from breaking. Therefore, since the state in which the locking claw 9p is locked around the outer periphery of the front engagement hole 23 is maintained, it is possible to prevent the front end engagement piece 9m from being detached from the front engagement hole 23. Furthermore, the shock absorbing part 27 presses the locking claw 9p downward in a bent state. Therefore, it is possible to more reliably prevent the front end engaging piece 9m from being detached from the front side engaging hole 23.

  In this way, even if the occupant A collides with the instrument panel 1 from the rear, the engagement state between the demister grill 9 and the instrument panel 1 is maintained, so that the demister grill 9 is prevented from scattering. Can do. Therefore, the passenger | crew A can be protected.

  In the above embodiment, the vehicle interior part mounting structure according to the present invention is applied to the demister grille 9 mounting structure. However, the present invention is not limited to this, and may be applied to a speaker grille mounting structure, for example.

  Moreover, in the said embodiment, although the vehicle interior component and the to-be-attached member to which it is attached were the demister grill 9 and the instrument panel 1, respectively, it is not limited to this, For example, a vehicle interior component and a to-be-attached member are Each may be a decorative panel and a door trim.

  Furthermore, in the said embodiment, although the slit 19a was provided in the width direction both sides of the impact-absorbing parts 21 and 27, you may provide the fracture | rupture planned line (tier line) 29 as shown in FIG. In this case, the planned fracture line 29 is provided by being cut to such an extent that the impact absorption of the impact absorbing portion 21 is not hindered. In addition, by providing the planned fracture line 29, the shock absorbing portion 21 is less likely to bend than when the slit 19a is provided. Therefore, it is possible to more reliably prevent the rear end engagement pieces 9f and 9k inserted into the rear engagement hole 19 from being detached from the rear engagement hole 19 during normal use.

  Furthermore, in the above embodiment, the outer periphery of the impact absorbing portions 21 and 27 and the rear engagement hole 19 and the front engagement hole 23 are formed relatively thin. For example, the shock absorbing portions 21 and 27 are in contact with the engaging pieces 9f, 9k, and 9m corresponding to the shock absorbing portions 21 and 27, and are bent to absorb the shock load. If possible, it may be formed with the same thickness as the base material 13a around the outer periphery of the engagement holes 19 and 23.
