Description

  The present invention relates to a vehicle side collision countermeasure structure for taking countermeasures against a side collision on a vehicle.

In automobiles (vehicles), in order to ensure occupant safety, measures are taken for each type of automobile collision (by collision direction) such as frontal collision and side collision.
As a typical example, for a frontal collision of an automobile, for example, as disclosed in Patent Document 1, there is a measure of providing an occupant movement suppression member inside a seat cushion of a seat device. This is because the occupant movement restraining member is placed in the vicinity of the thigh in front of the buttock of the occupant seated on the seat cushion, and the occupant seated on the seat cushion moves to the front of the vehicle due to inertia in the event of a frontal collision of the automobile. It is what suppresses it.

  Also, for side collisions, an impact bar member is provided in the door, or a guard member that extends in the vehicle width direction and is arranged to face the inner surface of the closed door as shown in Patent Document 2. There are measures to establish. In this case, an impact load applied from the door is received by the impact bar member or the guard member at the time of a side collision of the automobile, and the door is prevented from entering the vehicle interior.

JP 2002-46513 A JP-A-9-95264

In automobiles, attention is focused on measures against side collisions.
By the way, since the side collision countermeasure has been treated as a countermeasure different from the front collision countermeasure as in Patent Documents 1 and 2, conventionally, the structure of the side collision countermeasure and the structure of the front collision countermeasure are completely independent. The structure is adopted. For this reason, when adopting both the structure for the frontal collision and the side collision as described above, the number of parts and the number of assembling steps are likely to increase, and an increase in weight and a cost burden are likely to be imposed. In particular, it can be said that the side collision countermeasure has a greater burden on the weight and cost because the safety is greatly affected by the thickness and material of the member. Therefore, there is a need for a structure for countermeasures against frontal collision and side collision that suppresses weight and cost burden.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle side collision countermeasure structure that can also use the vehicle front collision countermeasure structure as a structural member for vehicle side collision countermeasures.

  In order to achieve the above-mentioned object, the invention according to claim 1 is disposed so as to be positioned in the vicinity of the thighs in front of the occupant's buttocks in a state where the occupant is seated inside the seat cushion of the seat device. A state in which the occupant movement restraining member that suppresses the forward movement of the occupant seated in the seat cushion at the time of the collision is extended to the vicinity of the opening on the side of the vehicle body along the vehicle width direction and the end on the opening side is closed It was formed so as to face the inner surface of the door, and the impact load applied from the door at the time of a side collision of the vehicle was received by the occupant movement restraining member.

With this configuration, the occupant movement restraining member prevents the occupant seated on the seat cushion from moving forward due to inertia during a frontal collision of the vehicle, and receives an impact load from the door during a side collision of the vehicle. It fulfills two functions of preventing entry into the passenger compartment.
According to the second aspect of the present invention, in order to further enhance the effect of suppressing the intrusion of the door into the vehicle compartment at the time of a side collision, the door includes a reinforcing member built in the door, and the reinforcing member is in a state where the door is closed. The occupant movement restraining member is arranged so as to face the end portion on the door opening side in the vehicle width direction.

The invention according to claim 3 is further provided between the end portion on the opening side of the occupant movement suppression member and the reinforcing member of the closed door so that the entry of the door is effectively suppressed by the occupant movement suppression member at the time of a side collision. The gap is occupied by the impact absorbing member, and after the impact load applied to the reinforcing member is relaxed by the impact absorbing member, it is transmitted to the occupant movement suppressing member through the impact absorbing member.
According to a fourth aspect of the present invention, in order to effectively suppress the entry of the door into the vehicle compartment at the time of a side collision, the reinforcing member is extended in the vehicle front-rear direction and receives an impact at the time of a side collision of the vehicle. An impact bar member was used.

  The invention according to claim 5 is based on the premise of a structure in which openings and doors are provided on both sides of the vehicle body so that a side collision on both sides of the vehicle body can be dealt with by one occupant movement restraining member. The restraining member is formed so that both ends in the vehicle width direction extend to the vicinity of the openings on both sides of the vehicle body along the vehicle width direction so as to face the inner surfaces of the doors in the closed state on both sides of the vehicle body. did.

  In the invention according to claim 6, the seat cushion is a bench seat type rear seat cushion so that a large number of passengers can be protected from both a frontal collision and a side collision by one occupant movement restraining member.

  According to the first aspect of the present invention, the occupant movement restraining member not only suppresses the occupant seated on the seat cushion from moving forward due to inertia during a frontal collision of the vehicle, but also from the door during a side collision of the vehicle. Under the impact load applied, it fulfills two functions to prevent the door from entering the passenger compartment. That is, the structure for preventing a frontal collision of a vehicle can be used as a structural member for preventing a side collision.

Therefore, it is possible to take measures against side collision of vehicles by diverting occupant movement suppression members used for countermeasures against frontal collisions of vehicles. Cost and weight can be reduced.
According to the invention of claim 2, since the impact load is received by the reinforcing member built in the door at the time of a side collision of the vehicle, the effect of the door suppressing the intrusion into the vehicle interior can be enhanced.

According to the invention of claim 3, the impact load at the time of a side collision of the vehicle is further mitigated by the impact absorbing member that occupies the gap between the opening side end portion of the passenger movement suppressing member and the reinforcing member of the closed door. Since it is transmitted to the occupant movement suppression member, the intruding door can be effectively suppressed by the occupant movement suppression member.
According to the fourth aspect of the present invention, the door intrusion suppressing action provided by the impact bar member extending in the vehicle front-rear direction can effectively suppress the door from entering the vehicle interior during a side collision of the vehicle.

  According to the invention of claim 5, even if it is a side collision on either side of both sides of the vehicle, it is possible to receive an impact load applied from the door by the occupant movement restraining member, and an impact from the door on one side. By transmitting the load to the vehicle body on the other side via the occupant movement restraining member, the impact load can be absorbed efficiently. Therefore, it is possible to more reliably suppress the door from entering the vehicle interior, and with a simple structure using one occupant movement restraining member, it is more effective against a side collision from both sides of the vehicle. Can be dealt with.

  According to the invention of claim 6, by using the bench seat type rear seat cushion, it is possible to protect a large number of passengers seated on the rear seat cushion from both frontal collisions and side collisions with one occupant movement restraining member. it can.

Hereinafter, the present invention will be described based on a first embodiment shown in FIGS.
FIG. 1 shows a rear side of a passenger compartment of a four-door (front and rear) type automobile (vehicle) to which the present invention is applied, FIG. 2 shows a state when the rear door is closed, and FIG. The state when removed is shown.
The main structure of the rear side of the automobile shown in FIGS. 1 to 3 will be described. In FIG. A vehicle compartment 2 is formed in the vehicle body 1 from the front side to the rear side. Further, a door opening 3 for a front door and a door opening 4 for a rear door (corresponding to the opening of the present application) are formed on both sides of the vehicle body 1 in the vehicle width direction. The door opening 3 and the door opening 4 include a side sill 8 disposed on the side of the front floor panel 5 and the rear floor panel 6 in the vehicle width direction, a roof side rail 9 disposed on the side of the roof panel (not shown), It is surrounded by a skeleton member such as a center pillar 10 and a rear pillar 11 that partition the door opening 3 and the door opening 4.

  As shown in FIGS. 1 to 3, the front door opening 3 is provided with a front door, for example, a laterally open front door (not shown), and the rear door opening 4 has a rear door, For example, a laterally opening type rear door 13 (corresponding to the door of the present application) is provided, and the passenger can get on and off the vehicle through the door openings 3 and 4. As shown in FIG. 6, the front door (not shown) and the rear door 13 are each provided with a sash portion 17a on an upper portion of a box-shaped door panel portion 17 formed by joining a door outer panel 15 and a door inner panel 16 to each other. A door trim 27 is provided on the inner surface of the portion 17. In the door panel portion 17 of the front door (not shown) and the rear door 13, a window member 17b passing through the sash portion 17a and an elevating device (not shown) for raising and lowering the window member 17b, as well as a reinforcing member that increases the rigidity of the door, for example A plurality of impact bar members 18, 19 extending in the front-rear direction of the vehicle are provided in the upper and lower stages. Each of the impact bar members 18 and 19 is arranged over the entire front and rear portions in the door panel portion 17 so as to receive an impact applied to the front door and the rear door 13 at the time of a side collision of the vehicle (only on the rear door side). Not shown).

  A front seat (not shown) is installed on the front floor panel 5. 1 to 4, a rear seat 20 (corresponding to the seat device of the present application) is installed on the rear floor panel 6. The rear seat 20 is installed adjacent to the door opening 4 near the rear wheel (not shown) of the vehicle, specifically, in front of the wheel house. The rear seat 20 is a seat cushion, for example, a bench seat type seat cushion 21 having a width dimension extending in the vehicle width direction of the passenger compartment 2 (up to the door openings 4 on both sides) and a seat back disposed at the rear of the seat cushion 21. 22 in combination. Of these, on both sides of the upper surface of the seat cushion 21 in the vehicle width direction, for example, seating portions 23 formed of seating surfaces recessed from other portions are formed. Also, on both sides of the seat back 22 in the vehicle width direction, for example, a backrest portion 24 formed by a backrest surface recessed from other portions is formed, respectively, and the waist of the occupant α is placed as shown in FIG. The occupant α is seated on the rear seat 20 by being lowered to the seating portion 23 and leaning back on the backrest portion 24. In particular, the seating surface of the seating portion 23 is inclined so as to be lowered toward the rear of the vehicle body. As shown in FIG. 4, the occupant α is good in that the heel portion β is disposed below the thigh γ. Sit in a sitting position.

  Although not shown, the rear seat 20 is assembled with a seat belt device that supports the upper body of the seated occupant α. As shown in FIGS. 1 to 6, the rear seat 20 is provided with countermeasures against other frontal collisions of the vehicle. As a countermeasure, a structure in which an occupant movement restraining member, for example, a cross pipe member 25 is inserted in the seat cushion 21 of the rear seat 20 in the vehicle width direction is used. As shown in FIGS. 4 and 5, the cross pipe member 25 is located in the vicinity of the thigh γ in front of the buttock β in the state where the occupant α is seated on the seat 23, specifically, the occupant. It is arranged so as to pass through the lower position of α thigh γ. With this structure, at the time of a frontal collision of the vehicle, the cross pipe member 25 prevents the occupant α seated on the seat cushion 21 from moving forward due to inertia.

  The countermeasures against the side collision are taken on both sides of the rear seat 20 as shown in FIGS. For this measure, a structure is used in which the end of the cross pipe member 25 faces the inner surface of the closed rear door 13 and the impact load applied from the rear door 13 is received by the cross pipe member 25 in the event of a side collision of the vehicle. It is. In this structure, an impact bar member 19 incorporated in the rear door 13 and a structure that can be used as it is for the rear doors 13 on both sides of the vehicle body are used.

  Explaining these points, for example, as shown in FIGS. 1 to 6, of the impact bar members 18 and 19, the rear end of the lower impact bar member 19 is positioned at the end of the cross pipe member 25. When the rear door 13 is closed, the impact bar member 19 faces the end of the cross pipe member 25 in the vehicle width direction with the door inner panel 16 interposed therebetween. It is like that. More specifically, the rear end of the impact bar member 19 is supported by the door inner panel 16 using, for example, a door bulkhead 26 as an impact absorbing member as a support leg. The front end of the remaining impact bar member 19 is supported by the door inner panel 16 via support legs 24 (shown in FIG. 2), and the entire impact bar member 19 is disposed near the door outer panel 15 (rear door). 13 to make it more susceptible to impact from 13). The door bulkhead 26 is formed of a structural part suitable for absorbing an impact load, for example, a box-shaped structural part having an outer shape larger than the diameter of the impact bar member 19. Further, as shown in FIG. 6, the door trim 27 is formed so that the inner surface portion of the door inner panel 16 in which the door bulkhead 26 is disposed faces the inside of the passenger compartment 2, for example, only the same portion has no trim portion. In the side collision of the vehicle, the impact load applied from the rear door 13 passes through the impact bar member 19 and the exposed inner surface portion 13a (cross) through the door bulkhead 26 that occupies the gap between the end of the impact bar member 19 and the door inner panel 16. It is structured to be transmitted to the inner surface portion facing the end of the pipe member 25.

  The following structure is used on the vehicle body 1 side with respect to the rear door 13. That is, as shown in FIGS. 1 to 6, for example, a pipe member extending in the vehicle width direction to the vicinity of each door opening 4 on both sides of the vehicle body is used for the cross pipe member 25 inserted through the seat cushion 21. Yes. Therefore, each end of the pipe member slightly protrudes from the inside of the seat cushion 21 to the side. Each end surface of the cross pipe member 25 is covered with an impact absorbing member provided on the vehicle body 1, for example, a vehicle body bulkhead 29. Specifically, as shown in FIG. 6, the vehicle body bulkhead 29 includes, for example, an upper portion of the side sill outer panel 8 a among the side sill 8 portions adjacent to the side portion of the seat cushion 21. For example, a flat box portion 30 continuous with the side sill 8 is formed and configured. The vehicle body bulkhead 29 protruding into the door opening 4 is arranged so as to overlap the end of the cross pipe member 25 in the vehicle width direction. The vehicle body bulkhead 29 is sized to occupy a gap between the inner surface portion 13a of the closed rear door 13 and the end of the cross pipe member 25. When the rear door 13 is closed, the vehicle body bulkhead 29 is It overlaps with the inner surface portion 13a. That is, the end of the cross pipe member 25 is configured to face the inner surface portion 13a of each rear door 13 on both sides that are closed. Thereby, the impact applied from the rear door 13 at the time of a side collision of the vehicle is received by the skeleton member surrounding the door opening 4 through the impact bar members 18 and 19 and the door panel portion 17, and also the inner surface portion 13 a of the rear door 13 and the vehicle body bulk. It is received by the cross pipe member 25 through the head 29. The cross pipe member 25 is supported by the vehicle body 1. Here, as shown in FIGS. 1 to 3 and 6, both end portions of the cross pipe member 25 inserted through the seat cushion 21 are supported by support plates 32 attached to the side surfaces of the flat box portion 30. The central portion is supported by a support plate 33 attached to the upper surface of the rear floor panel 6. As shown in FIG. 3, the cross pipe member 25 is configured to remain fixed to the vehicle body 1 side when the seat cushion 21 is removed. A notch 21a is formed in the lower part of the seat cushion 21 corresponding to the cross pipe member 25. When the seat cushion 21 is attached, the cross pipe member 25 is accommodated from the notch 21a and the seat cushion 21 has an inside. (See FIGS. 1 and 2).

Here, the seat cushion 21 and the cross pipe member 25 are configured separately, and the shape and the like on the seat cushion 21 side are matched to the cross pipe member 25, but the cross pipe member 25 is associated with the seat cushion 21. An internal structure may be adopted.
In the anti-collision structure configured as described above, for example, a frontal collision occurs in which the front part of the vehicle body collides during traveling of the automobile, and an impact load as indicated by an arrow F1 is applied to the front part of the vehicle as shown in FIG. Suppose. Then, the occupant α seated on the rear seat 20 tends to move forward of the vehicle as indicated by an arrow a due to the inertia of the collision.

At this time, since the cross pipe member 25 is disposed immediately below the thigh γ of the occupant α seated on the seat cushion 21, the cross pipe member 25 causes the heel portion β of the occupant α to be positioned as shown in FIG. Movement is regulated. Thereby, the movement of the seated occupant α forward is suppressed, and the safety of the occupant α can be ensured.
Further, for example, it is assumed that a side collision in which the front part of another vehicle collides with the rear door 13 and a lateral impact load indicated by an arrow F2 is applied from the side of the rear door 13 as shown in FIG.

At this time, the end of the cross pipe member 25 inside the seat cushion 21 faces the inner surface portion 13a of the closed rear door 14 and is ready to receive the impact load F2.
Thereby, the cross pipe member 25 receives the impact load F2. Then, the rear door 13 about to enter the passenger compartment 2 by the impact load F2 is received not only by the skeleton member surrounding the door openings 3 and 4, but also by the cross pipe member 25 disposed inside the seat cushion 21. Therefore, the intrusion of the rear door 13 is suppressed, and the safety of the occupant α can be ensured.

  Therefore, the cross pipe member 25 inside the seat cushion 21 not only suppresses the seated occupant α from moving forward in the front collision, but also receives the collision load F2 in the side collision and causes the rear door 13 to move to the vehicle interior. It fulfills two functions to suppress the intrusion into 2. In particular, since the cross pipe member 25 is disposed near the occupant α seated on the seat cushion 21, it is effective for preventing the rear door 13 from approaching the occupant α and also passes through the interior of the seat cushion 21. The habitability in the passenger compartment 2 is not disturbed. Further, at the time of a side collision, the center pillar 10 as well as the rear door 13 tries to enter the vehicle compartment 2, but the entry of the center pillar 10 can also be suppressed by suppressing the rear door 13 from entering the vehicle compartment 2.

Therefore, it is possible to take measures against the side collision by diverting the cross pipe member 25 used for the countermeasure against the frontal collision. That is, the structure for preventing a frontal collision of a vehicle can be used as a structural member for preventing a side collision as it is. As a result, due to the common use of the members, the number of parts and the number of assembling steps can be suppressed for the side collision countermeasure, and the cost and weight spent for the collision countermeasure can be reduced.
Further, when the reinforcing member built in the rear door 13 and the end of the cross pipe member 25 are opposed to each other, the reinforcing member is also subjected to an impact, so that the rear door 13 can be effectively prevented from entering the vehicle compartment 2. In particular, if the impact bar member 19 suitable for receiving an impact at the time of a side collision is used as the reinforcing member, and the impact bar member 19 is arranged to face the end of the cross pipe member 25, It is possible to effectively prevent the rear door 13 from entering the vehicle compartment 2.

  In addition, the gap between the end of the cross pipe member 25 arranged in the vicinity of the door opening 4 and the impact bar member 19 that is a reinforcing member of the closed rear door 13 is formed into a door bulkhead 26 that is an impact absorbing member, a vehicle body. When the impact load F2 occupied and applied by the bulkhead 29 is reduced by the bulkheads 26 and 29 and then transmitted to the crosspipe member 25, the crosspipe member 25 is fully utilized, and the passenger compartment of the rear door 13 is fully utilized. 2 can be prevented from entering.

  Further, when the cross pipe member 25 faces the inner surface of the closed rear door 13 on both sides of the vehicle body on both sides, the cross pipe member 25 causes the rear door to react to a side collision on either side of the vehicle. The impact load F2 applied from 13 can be received. In addition, since the impact load F2 from the rear door 13 on one side is transmitted to the flat box portion 30 on the other side via the cross pipe member 25, the impact load can be efficiently absorbed. Intrusion into the vehicle 2 can be more reliably suppressed, and a simple structure of using one cross pipe member 25 can more effectively cope with a side collision from both sides of the vehicle.

In particular, when a bench seat type is used for the seat cushion 21 through which the cross pipe member 25 is inserted, a single cross pipe member 25 protects many occupants α seated on the seat cushion 21 from both frontal collision and side collision. can do.
7 and 8 show a second embodiment of the present invention.

  In the present embodiment, the rear door 13 is provided with a gap between the end of the cross pipe member 25 disposed in the vicinity of the door opening 4 and the impact bar member 19 of the closed rear door 13 as in the first embodiment. Instead of the structure occupied by the head 26 and the bulkhead 29 provided on the vehicle body 2 side (side sill 8), only the bulkheads 35 and 36 provided on the rear door 13 (which correspond to the shock absorbing member of the present application) are used. A space between the end and the impact bar member 19 of the closed rear door 13 is occupied.

  Specifically, as shown in FIGS. 7 and 8, the cross pipe member 25 has a support plate provided on the rear floor panel 6 with an end (near the door opening 4) disposed on the side surface of the seat cushion 21. Support with 37. The door trim 27 of the rear door 13 forms a bulging portion 38 at the lower portion on the rear side, and the front wall of the bulging portion 38 overlaps the side surface portion of the seat cushion 21 when the rear door 13 is closed. Then, a bulkhead 35 that supports the end of the impact bar member 19 is provided on the side surface of the door inner panel 16 outside the passenger compartment, and the bulkhead 35 occupies the space between the door inner panel 16 and the end of the impact bar member 19. The bulkhead 36 is provided on the side of the door inner panel 16 on the vehicle interior side so that the bulkhead 36 occupies the space between the door inner panel 16 and the front wall of the bulging portion 38, and the rear door 13 is closed. In this case, the cross pipe member 25, the bulk head 36, the bulk head 35, and the impact bar member 19 are overlapped with each other.

Even in this way, as in the first embodiment, the cross pipe member 25 used for the countermeasure against the frontal collision can be used to take a countermeasure against the side collision.
Of course, the side collision countermeasure structure of the first embodiment and the side collision countermeasure structure of the second embodiment are as shown in FIGS. 1 to 3 of the first embodiment and FIG. 7 of the second embodiment. The rear floor panel 6 having the wall portion 6a rising from the front floor panel 5 is adopted, and the third embodiment shown in FIG. 9 and FIG. 10 are not limited to the structure that secures the foot space of the occupant α seated on the rear seat 20. As shown in the fourth embodiment, a rear floor panel that extends laterally continuously with the front floor panel 5 is adopted, and a recess 5a is formed in the front floor panel 5 so that a foot space for an occupant α seated on the rear seat 20 can be obtained. You may apply this invention to the vehicle which ensured.

Further, as in the fifth embodiment shown in FIG. 11, the vehicle body bulkhead 29 shown in the first and third embodiments is provided on the side sill inner panel 8b of the side sill 8 and closed with the end of the cross pipe member 25. A space between the inner surface portion 13a of the rear door 13 may be occupied by the vehicle body bulkhead 29, and the method of installing the two bulkheads is not limited.
However, in the second to fifth embodiments, the same parts as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  Note that the present invention is not limited to the above-described embodiment, and various modifications may be made without departing from the spirit of the present invention. For example, in the above-described embodiment, an example in which the side collision countermeasure structure of the present invention is applied to a bench seat type rear seat has been described. However, the present invention may be applied to a front seat without being a bench seat type. Absent. Also, the occupant movement suppression member may be other members instead of the cross pipe member. Of course, it is needless to say that the present invention may be applied to a vehicle having a door of a type other than the four doors.
