Description

  The present invention relates to a vehicle interior part. In particular, the present invention relates to a door trim provided in a vehicle trim and a vehicle interior component provided in a luggage side trim.

  Conventionally, door trims and luggage side trims are interior parts on the interior side of a vehicle, and, for example, a resin material or a resin material coated or cross-bonded to the resin material has been used. . The trim is provided with an armrest portion that is formed to protrude toward the vehicle compartment. The armrest portion is provided with a buffer function that protects the passenger against a side impact (side collision) applied to the vehicle.

  In addition, a storage box or the like for storing small items or the like is provided in the armrest portion. This storage box is composed of a box body and a lid, and when a load is applied to the armrest against a side collision, the reaction force increases due to the rigidity of the box body and lid, and a sufficient buffer function cannot be exhibited. In order to avoid the case, a technique for reducing the reaction force to protect the passenger is provided.

In Patent Document 1, when a load is applied to the storage box by the occupant at the time of a side collision, the storage box body is compressed and deformed to open the lid, thereby suppressing the reaction force to the occupant as much as possible. A vehicle door trim structure is provided.
JP 2006-315593 A

  However, in the conventional example, when a load is applied to the storage box by the passenger, the reaction force is reduced while the storage box body is compressively deformed, but if the allowable compression width is exceeded, the storage box body is sandwiched between the door trim and the door inner panel. Since no further deformation is possible, the remaining crushing occurs, and thereafter the reaction force increases. In addition, since the width of the storage box in the vehicle width direction is the maximum allowable compression width, the effect of absorbing and dispersing for a large load cannot be expected so much in this narrow range. Also, when the storage box body is compressed and deformed, the lid part opens and the reaction force is reduced, but if the storage box body deforms to some extent, the lid part is sandwiched and supported between the door trims, and thereafter Reaction force will increase.

  Accordingly, the present invention has been made in view of the above circumstances, and provides an interior component for a vehicle that applies as little reaction force as possible to a passenger even when a heavy load is applied to the vehicle trim from the passenger due to a side collision. The purpose is to do.

  In order to solve the above-described problems, in the vehicle interior part of the present invention, an armrest portion protruding toward the passenger compartment, a box body portion provided in the armrest portion, and a lid portion that opens and closes at an upper portion of the box body portion In the vehicular interior part, the fragile portion that becomes fragile is linearly provided on the outer peripheral surface of the box body portion, and the fragile portion is applied when a load from the side of the vehicle is applied to the armrest portion. Is provided at the upper portion of the box main body portion so as to correspond to the box main body engaging portion and the box main body engaging portion. And a lid engaging portion that releases the engagement state of the box body engaging portion when a load is applied from the side of the vehicle.

  According to this configuration, when a strong load is applied from the occupant to the armrest portion due to a side collision, the breakage portion that breaks from the fragile portion that becomes fragile is provided on the outer peripheral surface of the box main body portion. Therefore, the box main body is divided into two parts from the broken part, and the broken lower part of the box main body falls downward, so that the reaction force generated in the armrest part can be remarkably reduced. In addition, when a heavy load is applied from the occupant to the armrest portion due to a side collision, since the lid engagement portion is released from the engagement state of the box main body engagement portion, when a load is applied, The lid engaging part engaged with the box main body part is released, and the lid part can be released from the box main body part and released upward. Therefore, the reaction force caused by the lid being pinched is greatly reduced, and the collision absorption at the armrest portion can be sufficiently exhibited. Moreover, the box body upper part divided into two at the broken part becomes a frame shape by further releasing the lid upward, so that the rigidity can be further reduced, and the interior part for a vehicle that suppresses the reaction force as much as possible can be obtained. Can be provided.

  Moreover, in addition to the above-mentioned invention, it has the contact part provided with the inclined part which made the said vehicle compartment side high and made the said vehicle body side low, making the said lid part and the said box main-body part contact.

  According to this configuration, the contact portion that comes into contact with the lower surface of the lid portion and the upper surface portion of the box body is provided with an inclined portion in which the vehicle compartment side is raised and the vehicle outer side is lowered, so that the load from the vehicle side is lidded. It is easy to disperse the force upward and the upper surface of the box body downward. Therefore, the side face of the storage box is easily deformed following the deformation of the door trim that receives a load from the side of the vehicle, and the lid portion can be reliably discharged upward. As a result, the lid is not sandwiched between the armrest portions, and the generated reaction force can be greatly reduced.

  Moreover, in addition to the above-mentioned invention, it is characterized by the said weak part being provided in linear form along the direction extended diagonally upward as it goes to the said vehicle compartment side.

  According to this structure, since the weak part is linearly provided along the direction in which the vehicle compartment side is raised and the vehicle outer side is lowered, the box body is broken by the load applied from the vehicle side. The upper part of the box body including the lid is easily distributed upward, and the lower part of the box body is easily distributed downward. Therefore, the upper part of the box body including the lid part can be efficiently discharged upward. As a result, there is no reaction force caused by the lid being sandwiched between the armrest portions, and the collision absorption at the armrest portions can be sufficiently exhibited. Further, the lower portion of the box body can efficiently fall downward. As a result, there is no reaction force caused by the box body being sandwiched between the armrest portions, and the collision absorption at the armrest portions can be sufficiently exhibited.

  ADVANTAGE OF THE INVENTION According to this invention, even when a heavy load is applied to a vehicle trim from a passenger | crew by a side collision, the interior component for vehicles which does not give a reaction force to a passenger | crew as much as possible can be provided.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Embodiments of the invention will be described below with reference to the accompanying drawings. In addition, it demonstrates as an example which applied the storage box structure of the vehicle by embodiment of this invention to the storage box of the door trim for vehicles.

  Accordingly, two examples of the embodiment according to the present invention will be described with reference to the drawings with reference to FIGS.

  1 to 7 show Embodiment 1 of a storage box for a vehicle door trim according to the present invention. Hereinafter, the configuration of the storage box for the vehicle door trim in the first embodiment will be described.

  FIG. 1 is a configuration diagram schematically illustrating a vehicle door trim 2 and a storage box 4 according to a first embodiment of the present invention as viewed from the vehicle interior side.

  As shown in FIG. 1, the vehicle door 1 includes a vehicle door trim 2 that is painted or cross-coated on a resin material or a resin material to improve the interior appearance of the vehicle, and a vehicle in the middle of the vehicle door trim 2. The armrest part 3 protruded to the indoor side of the door, and a storage box 4 for storing small items provided in the armrest part 3. The storage box 4 has a rectangular shape and is composed of a box main body 6 installed so as to be embedded in the armrest portion 3 and a lid 5 which is a lid of the box main body 6 and is supported to be opened and closed. .

  Since the lid 5 serves as a cover part of the armrest portion 3, the lid 5 is a factor that improves the aesthetics of the interior of the vehicle by using colors and materials that match the vehicle door trim 2. In addition, since the box body 6 is embedded in the armrest part 3, when a load is applied to the trim around the box body 6 of the armrest part 3 due to a side collision, a relatively reactive force is generated compared to other parts. The structure is easy to create.

  FIG. 2 is a configuration diagram schematically showing the storage box 4 for the vehicle door trim according to the first embodiment of the present invention.

  As shown in FIG. 2, the storage box 4 includes a box body 6 and a lid 5 that is supported by the box body 6 so as to be freely opened and closed. The box body 6 has a box fixing portion 7 that is fixed to the armrest portion 3 on the side surface in the vehicle front-rear direction. A slit 8 a is provided so as to make one round of the side surface of the box body 6.

  The slit 8a has a fragile portion having a plurality of thinly open structures in a broken line shape. When the box body 6 receives a load from the side of the vehicle, the fragile portion of the slit 8a is cleaved, and the box body 6 is broken in the shape of the slit 8a.

  As shown in FIG. 3, it is the block diagram which expanded the C section of FIG. 2, and has shown the structure which the box main body 6 and the lid 5 of 4 of a storage box contact | connect. The lid 5 has a lid-side slope portion 16 in contact with the upper end of the box body 6 on the lower surface side at the peripheral edge portion. Further, a box body side inclined surface portion 17 corresponding to the lid side inclined surface portion 16 is provided at the peripheral edge portion of the upper end of the box body 6. In addition, the slopes of the lid-side slope portion 16 and the box body-side slope portion 17 have an inclined surface that is higher on the passenger compartment side and lower on the outer side of the vehicle, and is in contact with the inclined surface.

  When a load is applied to the storage box 4 from the vehicle compartment side toward the vehicle outer side in the vehicle width direction, the lateral force is also applied in the vertical direction due to the slope configuration of the lid side slope portion 16 and the box body side slope portion 17. Can be dispersed. Further, since it is an inclined surface in which the passenger compartment side is raised and the vehicle outer side is lowered, the lid 5 receives the upward force and the box body 6 receives the downward force. Open upward.

  As shown in FIG. 4, a cross-sectional view of part B of FIG. 2 shows a support part for the box body 6 and the armrest 3 of the storage box 4. A box support portion 7 is provided on a side surface of the main body box 6 in the vehicle front-rear direction, and is fixed to the arm wrist 3 by a storage box support boss 9.

  The box support portion 7 and the storage box support boss 9 are fixed by ultrasonic welding from the vehicle outer side in the vehicle width direction toward the passenger compartment.

  In FIG. 5, it is the side view which showed the support part of the box main body 6 and the armrest 3 of the storage box 4 from the rear side of the vehicle front-back direction to the front side. As shown in FIG. 5, the storage box support boss 9 that fixes the box support portion 7 provided on the side surface in the front-rear direction of the box body 6 and the armrest 3 is a groove for a support boss that becomes brittle at the root portion of the armrest 3. 10 is provided.

  When a load is applied to the storage box 4 from the vehicle compartment side toward the vehicle outer side in the vehicle width direction, the storage box support boss 9 is formed from the support boss groove 10 of the storage box support boss 9 joined to the armrest 3. It breaks and the storage box 4 cannot be supported. Therefore, the storage box 4 is supported only by the opening 12 of the armrest 3.

  In the present embodiment, the storage box support boss 9 is provided with a support boss groove 10 as a fragile portion on the joint side on the armrest side, and a load is applied to the storage box 4 from the vehicle compartment side in the vehicle width direction toward the vehicle outer side. Although it is configured to be easily broken when applied, the present invention is not limited to this. For example, a fragile portion may be provided at the joint portion between the box support portion 7 and the box body portion 6 so as to be easily broken.

  FIG. 6 is a cross-sectional view showing the storage box 4 attached to the armrest portion 3 of the vehicle door trim from the rear in the vehicle front-rear direction to the front. As shown in FIG. 6, the storage box 4 is attached to the opening portion 12 provided in the armrest portion 3, and the upper end of the box body 6 and the lid 5 are in contact with each other at the lid side slope portion 16 and the box body side slope portion 17. The lid 5 is in a closed state. The storage box support boss 9 for fixing the armrest portion and the storage box body 4 shown in FIG. 5 is omitted.

  As shown in FIG. 7 (a), when a load 21 is applied to the storage box 4 from the passenger compartment side in the vehicle width direction toward the vehicle outer side, the storage box support boss 9 is on the joint side on the armrest side. The support boss groove 10 is broken, and the storage box 4 is supported only by the opening. Further, when a load 21 is applied, the slit 8a provided around the side surface of the box body 6 breaks, and the box body lower portion 14 that is lower than the slit 8a falls downward.

  Further, when a load 21 is applied, the lateral force is also dispersed in the vertical direction due to the slope configuration of the lid-side slope portion 16 and the box body-side slope portion 17. Further, since the vehicle interior side is inclined and the vehicle exterior side is lowered, the lid 5 receives the upward force and the box body 6 receives the downward force. 14 can be dropped.

  After the box body lower part 14 falls and the lid 5 is lifted upward, the box body upper part 13 forms a frame shape and remains in the opening 12. As a result, when a load 21 is applied to the storage box 4 from the vehicle side to the vehicle outer side, the reaction force generated when the box body is pinched is caused to move downward in the box body lower portion 14. It can be significantly reduced by dropping it into The box main body upper part 13 stays in the opening part 12, but since it has a frame shape, its rigidity is low and it easily deforms against the load, so that the reaction force does not increase.

  Further, by providing the slit 8a, the force of the load 21 is consumed as energy for breaking the box body, so that the reaction force can be reduced compared to the state without the slit 8a. Furthermore, since the storage box 4 is easily deformed according to the force received by the load 21 due to the slit 8, the reaction force can be reduced.

  FIG.7 (b) is sectional drawing to which the D section of Fig.7 (a) was expanded. As shown in FIG. 7 (b), a lid engaging portion 18 is provided at the lower portion of the lid 5, and a box main body that pivotally supports the lid 5 in an openable manner corresponding to the lid engaging portion 18 at the upper end portion of the box main body 6. And an engaging portion 19. The box main body engaging portion 19 has a circular protruding structure for axial support, and the lid engaging portion 18 has a “C” shape so as to move along the circular shape.

  The lid engaging portion 18 is configured such that when the lid 5 is in the closed state, the open portion of the “C” shape is on the bottom. Therefore, the lid engaging portion 18 can be disengaged from the box main body engaging portion 19 when a force that causes the lid 5 to open upward acts. Therefore, the lid 5 can be detached from the box body 6.

  When a load 21 is applied to the storage box 4 from the vehicle compartment side toward the vehicle outer side in the vehicle width direction, the lateral force is increased in the vertical direction due to the slope configuration of the lid side slope portion 16 and the box body side slope portion 17. Also, the lid 5 receives a component force in the upward direction. Therefore, the lid engaging part 18 is released from the box body engaging part 19 and the lid 5 is opened upward.

  As a result, when a load 21 is applied to the storage box 4 from the side of the vehicle compartment toward the outside of the vehicle, the reaction force generated when the lid 5 is sandwiched releases the lid 5 upward. This can be significantly reduced.

  According to this embodiment, when a heavy load is applied from the occupant to the armrest portion due to a side collision, the outer peripheral surface of the box main body portion has a break portion that breaks from the weakened portion. Therefore, the box main body is divided into two parts from the broken part, and the broken lower part of the box main body falls downward, so that the reaction force generated in the armrest part can be remarkably reduced. In addition, when a heavy load is applied from the occupant to the armrest portion due to a side collision, since the lid engagement portion is released from the engagement state of the box main body engagement portion, when a load is applied, The lid engaging part engaged with the box main body part is released, and the lid part can be released from the box main body part and released upward. Therefore, the reaction force caused by the lid being pinched is greatly reduced, and the collision absorption at the armrest portion can be sufficiently exhibited. In addition, the upper portion of the box body divided into two by the breakage portion can further reduce the rigidity by releasing the lid upward, and can provide an interior part for a vehicle that suppresses the reaction force as much as possible. .

  In addition, the contact portion that contacts the lower surface of the lid portion and the upper surface portion of the box body is provided with an inclined portion in which the vehicle compartment side is raised and the vehicle outer side is lowered, so that the load on the lid portion is directed upward. The upper surface of the box main body can easily distribute the force downward. Therefore, the side face of the storage box is easily deformed following the deformation of the door trim that receives a load from the side of the vehicle, and the lid portion can be reliably discharged upward. As a result, the lid is not sandwiched between the armrest portions, and the generated reaction force can be greatly reduced.

  Thus, according to this embodiment, even when a heavy load is applied to the vehicle trim from the occupant due to a side collision, it is possible to provide an interior part for a vehicle that applies as little reaction force as possible to the occupant.

  In the present embodiment, the storage box support boss 9 has been described as a method for supporting the armrest portion 3 and the storage box 4, but is not limited thereto. For example, the opening 12 may be provided with a mechanism for locking the main body box 6 so that it can be fixed.

  In this embodiment, the box engaging portion 19 has a circular shape so that the lid 5 can be released upward when the load 21 is received, and the lid engaging portion 18 is the box engaging portion 19. However, the present invention is not limited to this. For example, the box engaging portion 19 may be deformed by receiving the force of the load 21 so that the engagement with the lid engaging portion 18 is released.

  Further, in the present embodiment, the number of the lid inclined portions 16 and the box body side inclined surface portion 17 installed, the size of the inclination, and the like are not limited. For example, an interior part for a vehicle that gently reduces the inclination of the lid inclined portion 16 and the box body side inclined surface portion 17 to reduce the gap between the lid 5 and the box body 6 and does not impair the aesthetic appearance of the armrest portion 3. Can be provided.

  Moreover, in this embodiment, although the slit 8a is provided in linear form so that the side of a storage box may make 1 round, it is not restricted to this. For example, in order to disperse the load 21 effectively, the load 21 may be provided linearly along a direction extending obliquely upward as it goes toward the passenger compartment side. This embodiment will be described as a second embodiment.

  8 and 9 show a second embodiment of a storage box for a vehicle door trim according to the present invention. Hereinafter, the configuration of the storage box for the vehicle door trim in the second embodiment will be described.

  FIG. 8 is a cross-sectional view showing the storage box attached to the armrest portion of the vehicle door trim according to the second embodiment of the present invention from the rear to the front in the vehicle front-rear direction. As shown in FIG. 8, a slit 8 b is provided so as to make one round on the side surface of the box body 6 of the storage box 4. The slit 8b is linearly provided along a direction extending obliquely upward as it goes toward the passenger compartment. The storage box 4 is attached and fixed to the opening 12. The storage box support boss 9 for fixing the armrest portion and the storage box body 4 shown in FIG. 5 is omitted.

  When the load 21 is applied to the storage box 4 from the vehicle side in the vehicle width direction toward the vehicle outer side, the slit 8b is inclined so as to raise the vehicle cabin side and lower the vehicle outer side. When 8b breaks, the force of the load 21 in the vehicle outer direction can be dispersed in the vertical direction by the slope.

  FIG. 9 is a cross-sectional view showing a state in which the storage box attached to the armrest portion of the vehicle door trim according to the second embodiment of the present invention receives a load from the side, from the rear to the front in the vehicle front-rear direction. As shown in FIG. 9, the armrest portion 3 receiving the load 21 applies a force to the storage box 4 while being deformed according to the load. The storage box is broken up and down at the slit 8b while being deformed according to the force received from the armrest.

  Since the slit 8b is inclined so as to raise the passenger compartment side and lower the vehicle outer side, the force received by the storage box is easily dispersed in the vertical direction, and the breakage of the slit 8b is promoted. Box 6 is bisected up and down. The box body lower part 14 below the slit 8b receives the dispersed downward force and falls downward. Further, the box body upper part 13 including the lid 5 above the slit 8b receives the dispersed upward force and is released upward.

  As a result, when a load 21 is applied to the storage box 4 from the passenger compartment side in the vehicle width direction toward the vehicle outer side, the reaction force generated by the box body being pinched causes the box body lower portion 14 to move downward. It can be significantly reduced by dropping it into In addition, when a load 21 is applied to the storage box 4 from the vehicle compartment side toward the vehicle outer side in the vehicle width direction, the reaction force generated when the lid 5 is sandwiched from the opening 12 causes the lid 5 to It can be significantly reduced by releasing upward.

  Since the storage box for the vehicle door trim in the second embodiment is configured as described above, it is possible to achieve substantially the same operations and effects as the storage box for the vehicle door trim in the first embodiment.

  In the above-described embodiment, the weakened portion is linearly provided along the direction in which the vehicle compartment side is raised and the vehicle outer side is lowered, so that the box body broken by the load applied from the side is 2 Thus, the upper part of the box body including the lid is easily dispersed upward, and the lower part of the box body is easily dispersed downward. Therefore, the upper part of the box body including the lid part can be efficiently discharged upward. As a result, there is no reaction force caused by the lid being sandwiched between the armrest portions, and the collision absorption at the armrest portions can be sufficiently exhibited. Further, the lower portion of the box body can efficiently fall downward. As a result, there is no reaction force caused by the box body being sandwiched between the armrest portions, and the collision absorption at the armrest portions can be sufficiently exhibited.

  Thus, according to this embodiment, even when a heavy load is applied to the vehicle trim from the occupant due to a side collision, it is possible to provide an interior part for a vehicle that applies as little reaction force as possible to the occupant.

  In the above-described embodiment, the fracture portion has been described using the slits 8a and 8b, but this is not restrictive. For example, a thinned structure may be provided on the entire circumference of the side surface of the storage box 4 so as to be easily broken.

  In the above-described embodiment, the load 21 applied to the armrest portion transmits the load force to the storage box 4 while the inner plate of the armrest is deformed, and the storage box 4 is deformed so as to follow the inner plate of the armrest. The slits 8a and 8b are broken. At this time, a side impact box contact portion is provided between the inner plate of the armrest and the storage box 4 that effectively transmits the load to the storage box 4 and breaks the storage box 4 at an early stage to reduce the reaction force. May be.

  The preferred embodiments of the present invention have been described above. However, the present invention can be variously modified and changed without departing from the concept of the claims.

  In the above embodiment, the example applied to the storage box provided in the armrest portion of the vehicle door trim has been described, but the present invention is not limited to this. For example, it can be similarly applied to components in a vehicle trim such as a door window switch and an ashtray.

  In the above embodiment, the example applied to the armrest of the vehicle door trim has been described, but the present invention is not limited to this. For example, the present invention can be similarly applied to components in a vehicle trim such as a luggage side trim.
