DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary structure of a vehicle in a passenger compartment.

[0002]

2. Description of the Related Art Auxiliary members typified by a cooling unit of an air conditioner are often provided on a passenger seat side of a vehicle-body panel constituting a front wall of a passenger compartment of an automobile. Regarding the auxiliary members provided in front of the occupant sitting in the passenger seat, in order to reduce interference with the occupant, the auxiliary members should be provided at a position which does not hinder the freedom of the legs of the occupant. Emphasis has been placed on measures such as having an external shape.

[0003] However, depending on the type of vehicle, there are various restrictions on the positional relationship between required equipment and passenger seats in the cabin, and auxiliary equipment provided on the passenger seat side of the cabin side wall of the vehicle body panel as described above. It is often difficult to provide a sufficient space between the member and the occupant.

Further, when the auxiliary member has a shape and dimensions necessary for satisfying the performance required of the auxiliary member, the tendency that the distance between the occupant in the passenger seat and the auxiliary member is narrowed is avoided. I can't.

Accordingly, in the prior art, as shown in FIG. 14, an auxiliary member 4 provided on the passenger seat 3 side of the passenger compartment 2 side wall of the vehicle body panel 1 receives an impact at the time of a collision of an automobile. When the vehicle body panel 1 is deformed like 1a, the vehicle body panel 1 retreats to the position indicated by 4a in the passenger compartment 2. At the same time, the knee 6 of the occupant 5 in the passenger seat 3 is 6
In this case, the user moves forward to the position indicated by a, and there is an unavoidable concern that the advanced knee 6a and the retreating auxiliary member 4a interfere with each other.

[0006]

Considering the state of interference between the knees of the occupant sitting in the passenger seat and the auxiliary members provided on the vehicle body panel in front of the passenger at the time of the collision described above, Depending on the state of deformation of the vehicle body panel in the above, the auxiliary equipment member installed on the vehicle body panel may be deviated in the vehicle front-rear direction in the cabin and retreat, and the auxiliary equipment member may be a passenger seated in the passenger seat. There is a problem in that interference with the knee is liable to occur, and further, when the distance between the auxiliary device member and the knee of the occupant is narrow, interference between the two becomes more likely to occur.

In view of the above, according to the present invention, the auxiliary member provided in front of the occupant sitting in the passenger seat takes any kind of retreating behavior in the passenger cabin due to deformation of the vehicle body panel at the time of collision. It is an object of the present invention to provide an auxiliary machine structure for an automobile which can prevent interference between the auxiliary machine and the vehicle.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the invention according to claim 1 is directed to a position of a knee of an occupant sitting in a passenger seat and an auxiliary member provided on a passenger compartment side wall surface of a vehicle body panel. The position of the auxiliary member and the knees of the occupant are prevented from being located in the same longitudinal direction of the vehicle and that the auxiliary member is not deflected in the longitudinal direction of the vehicle when the auxiliary member retreats in the passenger compartment due to deformation of the vehicle body panel in the event of a vehicle collision. And an auxiliary structure of an automobile capable of suppressing interference of the vehicle.

More specifically, a solution taken by the invention of claim 1 is that the passenger's knees in the passenger seat on the passenger side seat on the passenger compartment side wall surface of the vehicle body panel extending in the vehicle width direction so as to form the passenger compartment front wall. Auxiliary member provided at a position shifted in the vehicle width direction from a position on the direction extension line, and is fixed to the vehicle body strength member so as to contact the vehicle width direction side surface of the auxiliary device,
And guide means for guiding the auxiliary member so as to recede straight in the vehicle longitudinal direction at the time of a collision.

[0010] Further, the invention of claim 2 adds a structure in which the vehicle body strength member is a steering support member to the structure of claim 1.

[0011]

According to the construction of the first and second aspects of the present invention, the respective positions of the auxiliary member and the occupant's knee are not located in the same vehicle longitudinal direction.
Moreover, at the time of a collision, the auxiliary member retreats without being deflected in the longitudinal direction of the vehicle by the guide means. Therefore, even at the time of the collision, the positions of the auxiliary member and the occupant's knees are located in the same longitudinal direction of the vehicle. Is maintained.

[0012]

Next, an embodiment of the present invention will be described with reference to the drawings. However, first, a reference example similar to the embodiment of the present invention will be described with reference to FIGS. 1 to 7, and thereafter, the embodiment of the present invention will be described with respect to portions different from the reference example.

As shown in FIG. 1, an auxiliary component member 4 constituting an auxiliary component of an automobile extends in the width direction of the vehicle as shown on the left and right in the figure and extends to a passenger compartment 2 of a vehicle body panel 1 serving as a front wall of the passenger compartment 2. On the side wall surface, it is provided at a position displaced in the vehicle width direction from the position on the extension line in the vehicle front-rear direction of the knee 6 of the occupant 5 sitting on the passenger seat 3 facing the vehicle body panel 1.

The positional relationship of the auxiliary member 4 with respect to the knee 6 of the occupant 5 is such that the auxiliary member 4 occupies the inside of both knees 6 and 6 of the occupant 5 in FIG. ,
Similarly, the occupant 5 may occupy a position outside one of the knees 6 of both knees.

Regarding the deformation of the vehicle body panel at the time of the collision of the vehicle as described above, the vehicle body panel does not uniformly retreat to the passenger compartment side and bends not only at the time of a frontal collision but also at the time of a frontal collision. It is known to retreat in a state.

That is, as shown in FIG. 2, in an FR vehicle, a force P applied to the vehicle at the time of a collision is applied to the front bumper 7, and then, along a radiator, a pulley for electrical equipment and the like, along the center line in the vehicle longitudinal direction. By being transmitted to the arranged engine 8 and transmission 9, it is often concentratedly transmitted to the center of the vehicle body panel 1 in the vehicle width direction. As a result, the vehicle body panel 1 is often bent and deformed 1a toward the passenger compartment 2 in such a shape that a central portion in the vehicle width direction projects rearward in the vehicle front-rear direction.

Further, as shown in FIG. 3, in an FF vehicle, a force P applied to the vehicle at the time of a collision is applied to a front bumper 7 to transmit an impact load to a front side member F to which the front bumper 7 is attached. The load acts on the vehicle body panel 1 as well. As a result, the joint portion FG between the vehicle body panel 1 and the side member F is often bent and deformed 1b toward the passenger compartment 2 in such a shape as to retreat backward in the vehicle longitudinal direction. Reference numeral 8 denotes an engine, 9 denotes a transmission, and 10 denotes a cowl side panel.

When the vehicle body panel 1 is bent toward the passenger compartment 2 as shown by 1a or 1b due to the force P received by the vehicle at the time of collision, for example, the knee 6 of the occupant 5 in the passenger compartment 2 as shown in FIG. The auxiliary member 4 provided on the vehicle body panel 1 at a position shifted in the vehicle width direction retreats while deflecting in the vehicle front-rear direction, and at the same time, the knee 6 of the occupant 5 in the passenger compartment 2 The vehicle moves forward and backward due to inertia.

Therefore, the leading end of the retreating auxiliary member 4a on the occupant 5 side and the advancing knee 6a interfere with each other.
In order to reduce the interference at this time, in the one shown in FIG. 4, a rounded portion 11 as a knee interference reducing means is provided at the tip of the auxiliary device member 4 on the occupant 5 side. For this reason, the rounded portion 1 of the auxiliary member 4a that has been deflected and retracted during the collision.
1 and the knee 6a of the advancing occupant 5 can easily come into contact with each other obliquely.

Rounded portion 11 as knee interference reducing means
In the example illustrated in FIG. 4, the rounded portion 11 is formed by curving the left and right wall surfaces of the auxiliary device member 4 in the vehicle width direction at the front end portion on the occupant side. As shown in a plan view in FIG. 5, the roundness obtained by attaching a rounded body 11a having a curved surface on the occupant side to the occupant side wall portion of the auxiliary member 4 provided on the cabin side wall surface of the vehicle body panel 1. The shape part 11 can also be used.

FIG. 6 is a plan view showing a shock absorbing member 12 serving as a knee interference reducing means provided on the occupant side end of an auxiliary member 4 provided on the passenger compartment side wall of the vehicle body panel 1.
Is provided. 6 is a front end of the auxiliary member 4 on the occupant side in a state inserted between the wall surface of the auxiliary member 4 and the auxiliary core 4b enclosed by the wall surface. The impact absorbing member 12 is formed in the portion.

As shown in FIG. 7 as a plan view showing a shock absorbing member 12 as a knee interference reducing means, a passenger-side wall surface of an auxiliary member 4 provided on the passenger-side wall surface of the vehicle body panel 1. The impact absorbing member 12 may be attached to the portion.

In each of the examples in which the shock absorbing member 12 provided at the front end of the auxiliary member 4 on the occupant side is used as the knee interference reducing means, as shown in plan views in FIGS. When the front end portion of the occupant has a rounded shape, the knee interference reducing function in the case where the rounded portion 11 is used as the knee interference reducing means as exemplified in the plan view in FIGS. It is possible and convenient to have them together.

As described above, the knee 6 of the occupant 5 in the cabin 2 tries to move forward in the vehicle front-rear direction by inertia due to the force P received by the car at the time of collision, and is provided on the wall surface of the body panel 1 on the cabin 2 side. Even if the auxiliary member 4 is previously provided at a position shifted in the vehicle width direction with respect to the knee 6 of the occupant 5, if it is deflected in the vehicle front-rear direction by the bending deformation of the vehicle body panel 1 and retreats, Inevitably, the knees 6 of the forward occupant 5 and the auxiliary equipment members 4 that deflect and retreat cause interference. However, in the embodiment of the present invention shown in FIGS. 8 to 10 described below, it is possible to prevent the interference between the accessory member 4 and the knee 6 of the occupant 5.

That is, according to the embodiment of the present invention, instead of providing the knee interference reducing means for reducing the interference force at the time of contact between the auxiliary member 4 and the knee 6 of the occupant 5 as in the above reference example, Even if the body panel 1 is bent and deformed,
Is provided in the passenger compartment 2 to prevent the auxiliary equipment member 4 and the knee 6 of the occupant 5 from interfering with each other.

The guide means 13 extends in the vehicle width direction and is fixed to the vehicle width direction strength member fixed to the cowl side panel 10 or the front pillar base and the like. The guide member 13a is provided at a guide position at which the auxiliary member 4 can be retracted straight in the vehicle longitudinal direction with respect to at least one of the two.

The guide means 13 illustrated in FIG. 8 is provided with a cowl box member 14 serving as the vehicle width direction strength member.
The guide piece 13a is fixed to the cowl box member 14. The position where the abdominal plate of the guide piece 13a can come into contact with the side wall surface of the auxiliary member 4 is preferable.

According to the guide means 13 in this embodiment, the vehicle body panel 1 is bent and deformed as shown by 1a by a force P entering the vehicle from a front bumper (not shown) at the time of a collision, so that the vehicle body panel 1 When the auxiliary member 4 provided on the wall surface of the cabin 2 is deflected and tries to retreat, the cowl box member 14 having a high rigidity is used.
While the deflection of the auxiliary member 4 is suppressed by the guide function of the guide piece 13a fixed to the vehicle, the auxiliary member 4 recedes straight in the vehicle front-rear direction, moves along the vehicle front-rear direction, and occupies the position 4c. be able to.

On the other hand, the knee 6 of the occupant 5 moves forward and occupies the position indicated by 6a due to the inertia at the time of the collision. Since the machine member 4 was previously located at a position shifted in the vehicle width direction with respect to the knee 6 of the occupant 5, the auxiliary machine member 4c and the knee 6a of the occupant 5 do not have to be located in the same vehicle longitudinal direction. As in the state shown in FIG. 8, the interference between the two is suppressed. Reference numeral 15 denotes a steering support member, and 16 denotes a steering support member.
It is a knee protector arranged in

FIG. 9 shows another embodiment in which the guide means 13 is used. The guide means 13 in this embodiment is
The guide piece 13a is fixed to a steering support member 15 which is one of the vehicle width direction strength members. The position at which the guide piece 13a is fixed to the steering support member 15 is the same as the embodiment illustrated in FIG. The guide plate 13a is located at a position where the abdominal plate portion of the guide piece 13a is in contact with the side wall surface of the auxiliary member 4 to be guided.

The embodiment shown in FIG. 9 also has a high rigidity when the body panel 1 is bent and deformed by the force P applied to the automobile at the time of collision and the auxiliary member 4 is deflected to retreat. The deflection of the auxiliary member 4 is suppressed by the guide function of the guide piece 13a fixed to the steering support member 15, and the auxiliary member 4 recedes straight in the vehicle longitudinal direction.
occupies the position indicated by c.

The knee 6 of the occupant 5 moves forward and occupies the position indicated by 6a. However, the auxiliary member 4 and the knee 6 of the occupant 5 are set in a positional relationship in which they are displaced from each other in the vehicle width direction in advance. As a result, the auxiliary equipment member 4c that has been guided backward so as to be straight in the vehicle longitudinal direction and the knee 6a of the occupant 5 who has advanced forward
Are not located in the same vehicle longitudinal direction, so that interference between them is suppressed.

As shown in FIG. 10, the guide means 13 is fixed to, for example, a steering support member 15 which is a strength member in the width direction of the vehicle, and has two guide pieces 13a which contact the left and right side surfaces of the auxiliary member 4 respectively. Preferably, such a guide means 13 has an excellent guide function of suppressing the deflection of the auxiliary member 4 in the vehicle front-rear direction at the time of a collision and retreating straight in the vehicle front-rear direction.
Among them, the guide means 13 shown in FIG. 10 is particularly close to the hard auxiliary machine core 4 b inside the auxiliary machine member 4 and the guide piece 1.
A concave portion is provided on the wall surface of the auxiliary device member 4 so that the auxiliary member 3a can be located, and the guide piece 13a is located in the concave portion.

When the auxiliary member 4 attempts to deflect and retreat in a passenger cabin during a collision, such a guide means 13 is made of, for example, a synthetic resin material or a metal thin plate which is more fragile than the auxiliary core 4b. The peripheral wall of the auxiliary member 4 is removed by receiving a strong pressure from each of the guide pieces 13a fixed to the vehicle width direction strength member, and the auxiliary member 4 is hardened by the hard auxiliary core 4b inside the guide piece 13a. Therefore, a straight retreat in which the deviation in the vehicle width direction when the auxiliary member 4 retreats in the vehicle front-rear direction is minimized can be achieved.

In the embodiment using the guide means 13 as described above, as shown in FIG. 10, two guide pieces 1 located on both sides of the auxiliary member 4 in the vehicle width direction.
In addition to the one having the guide piece 3a, one guide piece 13 is provided at a position where the auxiliary member 4 can be deflected in the longitudinal direction of the vehicle when the auxiliary member 4 retreats in a collision.
Even with the provision of “a”, a guide function for straightly retreating the auxiliary member 4 in the vehicle front-rear direction can be achieved.

The side that deflects in the longitudinal direction of the vehicle when the auxiliary member 4 retreats in the event of a collision, in other words, the side on which only one of the guide pieces 13a constituting the guide means 13 is provided is the right cab. In the FR car and the left cab FF vehicle, the auxiliary member 4 is on the left side in the vehicle width direction, and in the left cab FR car and the right cab FF vehicle, the auxiliary member 4 is on the right side in the vehicle width direction. What is necessary is just to select based on providing.

Further, the mounting position of the steering support member 15, which is a strength member in the width direction of the vehicle, tends to be low due to a demand for a low bonnet height of the vehicle. The upper part of the auxiliary member 4 and the steering support member 1 are retracted in the backward direction.
There is a risk of contact with No. 5. Therefore, it is desirable to provide a contact obstruction avoiding means for avoiding obstruction such as bending of the steering support member 15 due to the contact in an area where the auxiliary device member 4 and the steering support member 15 are in contact with each other. The contact obstruction avoiding means shown as 17 in the figure includes a guide bracket provided on the steering support member 15 as shown in FIG.
As shown in FIG. 2, a guide cover is provided on the upper end of the auxiliary member 4 on the occupant side, and FIG.
As shown in (1), it can be appropriately selected from those having a guide cam surface provided on the upper end of the auxiliary member 4 on the occupant side.

The auxiliary member 4 in each of the above embodiments is
Auxiliary structure which cooperates with the guide means even if the auxiliary member 4 does not always protrude into the passenger compartment 2 but protrudes in the event of a collision. Needless to say, this can be done.

[0039]

As described above, according to the auxiliary structure of the vehicle according to the first and second aspects of the present invention, the position of the knee of the occupant on the passenger seat side in the vehicle width direction is shifted from the position on the vehicle longitudinal extension line. The auxiliary member and the vehicle body strength member are fixed so as to contact the side surface in the vehicle width direction of the auxiliary member, and guide the auxiliary member to recede straight in the vehicle longitudinal direction at the time of collision. Since the auxiliary member is retracted without deflecting in the width direction of the vehicle at the time of a collision because the guide member is provided, it is possible to maintain a state in which the positions of the auxiliary member and the occupant's knee are not located in the same vehicle longitudinal direction. Therefore, it is possible to prevent interference between the accessory member and the occupant's knee.
