Description

  The present invention relates to a vehicle side door structure including an armrest formed by bulging from a door trim provided on the side of a vehicle interior to the vehicle interior, and particularly to a separate armrest part connected to the rear end of the armrest main body. It is related with the side door structure of the vehicle which separated from the door trim and was comprised so that a movement to the vehicle front or back was possible.

  Conventionally, an armrest of a vehicle is formed by bulging from a door trim provided on a vehicle interior side of a door inner panel to a vehicle interior side so that an occupant seated on a seat device mounts an arm portion or an elbow portion. Stiff enough to withstand the load input from the arm. The installation height of such an armrest corresponds to the vicinity of the lower part of the chest of the seated occupant. Therefore, a rib or the like that is broken or bent by a load at the time of a side collision is provided in the internal space of the armrest to reduce the impact from the armrest that the occupant receives during a side collision.

  In the armrest provided with the ribs as described above, as a result of the armrest coming into contact with the occupant, the ribs are broken or bent and the impact received by the occupant is reduced. However, the rear end portion of the armrest close to the lower part of the chest of the seated occupant is formed in a gently curved shape so as to converge smoothly to the door trim side from the viewpoint of design. It is difficult to arrange a shock absorbing rib or the like. Therefore, the rigidity of the rear end portion of the armrest is increased as compared with the central portion where the ribs and the like are disposed. Therefore, in order to avoid interference between the occupant and the armrest, the armrest is also retracted from the vicinity of the occupant at the timing when the side collision load is applied to the vehicle interior side during a side collision.

The door trim structure described in Patent Document 1 is provided with an armrest separation portion that can be separated from the door trim body by a rear half portion of an armrest facing the occupant in the vehicle width direction and a door trim portion located below the rear half portion of the armrest, The upper portion of the armrest separation portion is connected to the door main body portion by a bracket that can be deformed in the vehicle width direction, and the lower portion of the armrest separation portion is rotatably attached to the door main body portion by the lower attachment portion. The bracket is joined to the door inner panel using a pin, an upright portion, a bracket body portion folded upward at a folded portion at the lower end of the upright portion, and an upper portion of the armrest separating portion at the upper end portion of the bracket body portion. And a bent portion.

In this door trim structure, a buffer member penetrating the door inner panel is provided between the door outer panel and the door inner panel, and the buffer member is in contact with the outer portion of the compartment below the armrest of the armrest separation portion. As a result, when a side collision load is input from the outside, the buffer member pushes the outer portion of the armrest separating portion toward the passenger compartment, so that the bracket body rotates around the folded portion toward the passenger compartment. Then, the armrest separation part rotates around the lower attachment part toward the vehicle interior side, and as a result, the rear half of the armrest in the armrest separation part moves to the lower position.

JP 2008-100581 A

In the door trim structure of Patent Document 1, the armrest separation portion can be moved downward at the timing when the side impact load is applied toward the vehicle interior side. However, the armrest separating portion only moves downward by an amount corresponding to the amount of deformation of the bracket (the width of the bracket body portion), and the amount of movement necessary to avoid contact between the occupant and the armrest cannot be secured sufficiently. The armrest may interfere with the abdomen and lower back of the passenger's chest.

In view of the foregoing, it is conceivable to increase the width of the bracket body in order to increase the amount of deformation of the bracket. However, the vehicle weight is newly increased. In addition, since the armrest separating portion is a mechanism that moves toward the vehicle interior side with the lower mounting portion as a center, that is, as the amount of rotation of the armrest separation portion increases, the width of the bracket body portion increases. There is also a possibility that the possibility of contact between the armrest and the occupant is promoted as the operation is performed.

At the time of a side collision, the door side shock absorbing member 21 moves toward the trim side shock absorbing member 26 and comes into contact therewith, so that the impact on the occupant's waist and the like is mitigated by the door side shock absorbing member 21 and the trim side shock absorbing member 26. can do.

The shock absorbing member accommodating portion 25 is integrally formed so as to bulge from the door trim 7 toward the vehicle interior side below the separate armrest portion 32. The upper portion of the shock absorbing member accommodating portion 25 is formed by the door trim side mounting portion 22, and the front portion of the shock absorbing member accommodating portion 25 is formed integrally with the rear portion of the door pocket portion 24.

Next, the behavior of the separate armrest part 32 at the time of a side collision will be described.
When another vehicle collides with the vehicle 1, the outer panel 5 enters the inside of the vehicle width, and the flat portion 13 a of the third protruding portion 13 comes into contact with the flat portion 11 a of the first protruding portion 11. After the contact between the flat surface portion 13a and the flat surface portion 11a, the second convex portion 12 moves toward the inside of the vehicle width as the first convex portion 11 moves and deforms.

  As shown in FIG. 9, when the movement of the second projecting portion 12 toward the inside of the vehicle width proceeds, the second door side installed on the inner surface in the vehicle width direction of the flat surface portion 12 a of the second projecting portion 12. The shock absorbing member 29 comes into contact with the side surface 32c of the separate armrest part 32, and pushes the separate armrest part 32 toward the vehicle interior side. The side impact load acts on the cutout portion 42a of the fitting portion 42 via the projection portion 41, and in the case of a side impact load inward of the vehicle width greater than a predetermined value, the projection portion 41 breaks or bends the cutout portion 42a. Then, the armrest separate part 32 is pushed toward the vehicle interior side. At this time, when a side collision load is input obliquely from the rear, the first guide portion 43a guides the armrest separate portion 32 forward with respect to the protrusion 41, and the rear end portion 31d of the armrest main body portion 31 is separate from the armrest. In order to guide the front end portion 32d of the portion 32 forward, the separate armrest separate portion 32 moves forward as the separate armrest separate portion 32 moves toward the vehicle interior side. In addition, when a side collision load is input obliquely from the front, the second guide portion 43b guides the separate armrest portion 32 backward with respect to the protrusion 41, and therefore the separate armrest portion 32 moves toward the vehicle interior side. The separate armrest part 32 moves rearward. Thereby, a contact with a passenger | crew and the armrest separate body part 32 can be avoided.

Next, the sheet apparatus 3 will be described.
As shown in FIGS. 1 to 3, the seat device 3 is arranged at a predetermined distance from the vehicle interior side of the door trim 7. The distance between the door trim 7 and the seat device 3 is set to be larger than the width of the armrest separate part 32 in the vehicle width direction, and when the armrest separate part 32 is separated from the door trim side mounting part 22 in a side collision, the door trim 7 And the sheet apparatus 3 are configured to be dropable.

The seat device 3 includes a seat cushion 51 slidable in the front-rear direction with respect to the vehicle 1, a seat back 52 that accommodates a seat back frame (not shown) and a pad material (not shown), and an outer side of the seat back 52 in the passenger compartment. The side airbag device 60 is disposed at an upper position, and a headrest or the like. In addition, a weak portion that can be partially broken is formed in the pad material above the middle step in the vertical direction outside the passenger compartment of the seat back 52 so that the side airbag device 60 can be operated.

The side airbag device 60 is fixed to a seat back frame outside the passenger compartment, for example, above the right middle step of the seat back 52, and includes an inflator 61, a side airbag 62 folded in a roll shape, and the like. The inflator 61 accommodates a gas generating agent in, for example, a vertically long cylindrical case, and in the event of a side collision, the gas generating agent reacts with a driving current output from a side collision detection sensor (not shown), thereby causing a side airbag. In this structure, 62 gas for development is instantaneously generated.

The side airbag 62 is configured to be deployable between the door trim 7 of the front side door 4 and the seat device 3 at the time of a side collision. The side airbag 62 includes an upper bag part 62a that is deployed at a position corresponding to the chest and abdomen of the occupant, and a lower bag 62b that is deployed at a position corresponding to the occupant's waist. When the side airbag 62 is deployed, the deployment amount, the deployment timing, and the deployment direction are set so that the upper bag portion 62a contacts the rear end portion 32e of the separate armrest portion 32 and pushes the separate armrest portion 32. ing.

Next, the operation of the side airbag device 60 at the time of a side collision will be described.
As shown in FIGS. 10 to 12, in the side airbag device 60, when another vehicle side impacts on the vehicle 1 and a side collision is detected by the side collision detection sensor, the occupant is caused to enter the door trim by the side collision load. 7 and the gas for deployment generated from the inflator 61 are supplied to the side airbag 62 in a moment until the secondary collision with the armrest 30 or the armrest 30 (an armrest separate part 32). Accordingly, the upper bag portion 62a and the lower bag 62b are deployed forward from the side airbag device 60 between the door trim 7 and the seat device 3, and contact between the occupant and the door trim 7 can be avoided.

Since the upper bag part 62a contacts the rear end part 32e of the armrest separate part 32 at the time of a side collision, the front side door 4 is disengaged after the engagement between the projection part 41 and the fitting part 42 as shown in FIG. When the armrest separate part 32 is not sufficiently separated from the door trim side mounting part 22 or the side collision from the diagonally forward direction is small. Even when a load is input, the separate armrest part 32 can be actively pushed forward in cooperation with the rear end part 31d of the armrest body part 31 and the first guide part 43a. The amount of forward movement of 32 can be ensured.

Next, functions and effects of the side door structure will be described.
This side door structure has a door trim 7 provided on the vehicle interior side of the front side door 4 and an armrest 30 on which an occupant's arm portion swelled on the door trim 7 toward the vehicle interior side is placed. In the side door structure of the vehicle 1 in which the seat device 3 is disposed at a position overlapping with the front side door 4 in the side view of the vehicle body, the armrest 30 receives a side impact load from the outside to the front side door 4. At least a part of the armrest 30 facing the occupant in the vehicle width direction (a separate armrest part 32) is provided so as to be movable forward or backward of the vehicle after being disconnected from the door trim 7.

According to this side door structure, when a side impact load is input to the front side door 4 from the outside, the armrest separate part 32 that is a part of the armrest 30 is separated from the door trim 7 and is separated from the armrest main body 31 by the vehicle. Because it is configured to be able to move forward or backward, the armrest separate part 32 facing the occupant is moved to a position away from the occupant before contact between the occupant and the armrest 30 without affecting the vehicle weight or design. Can be made. Moreover, since the separate armrest part 32 moves forward or backward with respect to the armrest body part 31, the separate armrest part 32 also contacts the upper body including the chest, the abdomen, the waist, or the like corresponding to the lower position of the chest. In order to avoid interference between the occupant and the separate armrest part 32, and because the separate armrest part 32 moves separately from the door trim 7, in order to avoid interference between the occupant and the separate armrest part 32. The necessary amount of movement of the separate armrest 32 can be ensured.

The armrest 30 is formed by an armrest body 31 formed integrally with the door trim 7, and an armrest separate body 32 separate from the door trim 7 formed to be continuous with the rear end of the armrest body 31. An engagement mechanism 40 is provided on the lower end portion of the separate body portion 32 and the door trim side attachment portion 22 that faces the lower end portion and attaches the separate armrest portion 32. A projection 41 projecting from one end of the lower end portion and the door trim side mounting portion 22 to the other side, and a fitting formed on the other end of the lower end portion 33 of the separate armrest portion 32 and the door trim side mounting portion 22 so that the projection portion 41 can be fitted. Since the joint portion 42 is provided, the separate armrest portion 32 can be positioned on the door trim side mounting portion 22, and the separate armrest portion 32 can place the arm portion of the occupant and It is possible to support the load that is input from the arm portion.
Since the first and second guide portions 43a and 43b that are connected to the notch portion 42a formed at the outer end portion of the fitting portion 42 and are inclined toward the front and rear of the vehicle are provided on the inner side in the vehicle width direction. When the load is applied, the notch portion 42a is broken or bent to release the fitting between the projection 41 and the fitting portion 42, and the movement of the armrest separate portion 32 toward the vehicle interior is permitted, The armrest separate part 32 can be guided forward or backward of the vehicle in synchronism with the movement toward the vehicle interior.

A front end portion 32d of the armrest separate body portion 32 is formed in contact with the rear end portion 31d of the armrest main body portion 31, and the rear end portion 31d of the armrest main body portion 31 is configured to be inclined so as to move forward in the vehicle interior. Therefore, when a side collision load is input to the front side door 4 from the outside, the rear end portion 31d of the armrest body 31 shifts the moving direction of the separate armrest 32 to the front of the vehicle toward the vehicle interior side. It can guide and can avoid interference with a crew member and separate armrest part 32 reliably.

Since the door trim side mounting portion 33 is configured to be inclined such that the inner end in the vehicle width direction is located below the outer end in the vehicle width via the two inclined portions 33b and 33d, the separate armrest 32 and the trim side Simultaneously with the disengagement with the attachment portion 22, the separate armrest portion 32 can be actively guided downward, and interference between the upper body of the occupant and the separate armrest portion 32 can be further avoided. Moreover, since the door trim side mounting portion 22 includes the horizontal portions 22a and 22c, the armrest separate portion 32 can place the arm portion of the occupant and can reliably support the load input from the arm portion.

The inner panel 6 includes a first projecting portion 11 projecting outward in the vehicle width direction at a position above the shock absorbing member housing portion 25 and corresponding to a side of the separate armrest portion 32, and the first projecting portion. 11 has a second projecting portion 12 projecting inward in the vehicle width direction, and when the second projecting portion 12 comes into contact with the separate armrest portion 32, the engagement between the protrusion 41 and the fitting portion 42 is released. Since the separate armrest part 32 is moved from the door trim side attachment part 22 to the front or rear of the vehicle, the side impact load can be quickly transmitted to the separate armrest part 32, and the armrest separate part 32 can be moved inward of the vehicle width. The movement can be started early with respect to the time when the front side door 4 enters the vehicle interior side.

Since the second door-side impact absorbing member 29 that can come into contact with the separate armrest portion 32 when a side impact load is input to the front side door 4 is provided at the inner end in the vehicle width direction of the second projecting portion 12, the armrest After the separate body portion 32 is moved, the second door side shock absorbing member 29 reduces the impact on the occupant over a wide range while preventing direct contact between the occupant and the second projecting portion 12. be able to.

The door trim 7 has an impact absorbing member accommodating portion 25 that accommodates a trim side impact absorbing member 26 that bulges toward the vehicle interior side at a position below the separate armrest portion 32 and can absorb a side impact load input to the front side door 4. I have. Thereby, the armrest separate body part 32 can be moved to a position where interference with the occupant is avoided, and the impact mitigating function of the trim side impact absorbing member 26 can be secured to reduce the occupant's impact during a side collision.

The seat back 52 of the seat device 3 includes an airbag device 60 having a side airbag 62 that can be deployed between the front side door 4 and the seat device 3 when a side impact load is input to the front side door 4. Since the separate armrest body portion 32 is configured to move in the direction of deployment of the airbag 62 toward the vehicle interior side, the separate armrest body portion 32 is moved using the deployment force of the side airbag 62 forward of the vehicle. Therefore, the movement of the separate armrest part 32 to the front of the vehicle is small, and the amount of movement of the separate armrest part 32 in the front-rear direction due to a side impact load is sufficiently small. Even if it is not possible, the amount of movement of the separate armrest 32 can be obtained.

When the side airbag 62 is deployed, the upper bag 62a pushes the rear end portion 32e of the separate armrest part 32 forward of the vehicle, so that the deployment force of the upper bag 62a toward the front of the vehicle is efficiently applied to the separate armrest part 32. The amount of movement of the armrest separate part 32 to the front of the vehicle can be further increased.

Next, the side door structure of Example 2 is demonstrated based on FIG. 13, FIG.

It is configured to be matable. The guide part 43A includes a front guide part 43c and a rear guide part 43d that are connected to the notch part 42b and are inclined forward toward the inner side in the vehicle width direction. The front guide portion 43c and the rear guide portion 43d are formed from the front and rear end portions of the notch portion 42b to the side surface portion 32c. Since the vehicle front-rear direction width of the front side guide part 43c and the rear side guide part 43d is larger toward the outside of the passenger compartment, the guide part 43A is formed in a substantially trapezoidal shape that is inclined rearward in the vehicle width direction when seen in a plan view. . Therefore, after the engagement between the protrusion and the fitting portion is released at the time of a side collision, the front guide portion and the rear guide portion can be guided forward of the vehicle as they move toward the vehicle interior side with respect to the protrusion 41. That is, the separate armrest part 32A can be moved toward the front of the vehicle.

Since the separate armrest part 32A is disengaged from the door trim 7 so as to be movable forward of the vehicle and the width of the guide part 43A in the vehicle front-rear direction is larger toward the outside of the passenger compartment, a side impact load is input from an oblique direction. Even in this case, the separate armrest part 32A can be smoothly moved to a relatively open space in front of the occupant without being obstructed by the seat device 3 or the like.
