Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is related to the floor of a car, and more specifically, it is used when a collision occurs. In particular, it relates to the floor of an automobile that has safety measures for the driver.

0002

[Conventional technology]

Several seats including a driver's seat are arranged inside the car, and The steering column faces the driver's seat from the dash panel that divides the interior. A steering wheel is attached to the steering column. Therefore, the driver should hold the steering column between his legs while driving. Sit in the seat and operate the steering wheel to control the car. It turns out.

0003

[Problem that the idea aims to solve]

By the way, while driving a car, especially when a collision occurs from the side, The impact causes the driver's seating posture to change, causing his knees to shift from the steering wheel. It also goes under the steering wheel, between the driver's knees and feet, that is, the driver's lower legs. It is conceivable that the person may be restrained between the column and the indoor floor. like this In such situations, there is a risk that an excessive compressive load will be applied to the driver's lower legs, so this is not desirable. There isn't.

0004 For this reason, there is a so-called "knee" system that prevents the knees from getting under the steering column. - Cars equipped with protectors are also known, however, in the event of a collision, The changes in the sitting posture of drivers who drive are not uniform, so even if a knee protector is used, Even if there is, there is a possibility that the driver's knees will go under the steering column. cannot be excluded.

[0005] This idea was made based on the circumstances mentioned above, and its purpose is If the occupant's lower legs contact the floor due to a change in the occupant's posture while seated in the seat, Even if a situation occurs where the occupant is restrained between the vehicle and other fixed parts, the An object of the present invention is to provide an automobile floor that can reduce the compressive load caused by the vehicle.

[0006]

[Means to solve the problem]

The floor of the car of this invention consists of the floor body of the car body to which the seats are attached, and It is integrally provided in the area in front of the seat of the main body of the floor, and is designed to protect the feet of passengers seated in the seat. When the load applied to the seat front area exceeds a predetermined value, the seat front area The structure includes a fragile portion that can be deformed downward.

[0007]

[Effect]

According to the above-mentioned floor, since the weak part is provided in the area in front of the seat, for example, If this seat front area is located in front of the driver's seat, please A situation has arisen where the driver's lower legs are restrained between the steering column and the floor. However, if the load applied from the driver's feet, that is, the heel, to the area in front of the seat exceeds a specified value. In this case, the area in front of the seat, which is a part of the floor, starts from the weakened part. deforms downward, thereby preventing excessive compressive loads from being applied to the driver's lower legs. .

[0008]

【Example】

Referring to FIG. 1, a portion of the interior of an automobile is schematically shown. this The interior of the room is divided vertically by a floor 10 and a roof 12. The front of the vehicle is divided by a dash panel 14. A driver's seat 16 is installed on the floor 10. A steering wheel 18 is arranged at the front. This steering wheel The steering wheel 18 is attached to one end of the steering column 20, and The ring column 20 extends from the dash panel 14 toward the driver's seat 16. . Although not shown, the other end of the steering column 20 is connected to a rack and pinion machine. It is connected to the tie rod of the front wheel via a structure. In addition, in FIG. 1, reference numeral 22 is Instrument panel, 23 is the windshield, 24 is the knee protector. It shows.

[0009] The floor 10 includes a floor panel 26 and a floor panel 26, as shown in FIG. It consists of a floor stringer 28 that reinforces the panel 26. this floor The trigger 28 is made of a gutter-like member that extends in the longitudinal direction of the vehicle body, and is connected to the floor panel 2. 6 via a flange 30. Top surface of floor panel 26 A floor carpet 32 etc. is laid on the floor.

0010 Then, on the floor 10, the area in front of the driver's seat 16, that is, the driver's seat is seated. A weakened portion 34 is formed in the region where the feet of a seated driver are placed. This vulnerability As shown in FIG. 2, the portion 34 recesses a portion of the floor panel 26 downward. It consists of a recess 36 that is integrally formed in the front and back direction of the vehicle body. While having a predetermined width dimension, as shown in FIG. A predetermined area in the transverse direction of the stringer 28, that is, a driver seated in the driver's seat 16 It extends over an area in which both feet of the person can be located. Furthermore, the recesses 36 intersect with each other. The lower string 28 is also cut out by the recess 36, making it fragile. It has become.

[0011] If the above-mentioned floor 10 is provided, collisions, especially from the side, can be avoided while the vehicle is running. Therefore, due to the impact, the driver's seating position changed, and the driver's seating position changed as indicated by the chain double-dashed line in Figure 1. As shown, in the unlikely event that the driver's knees go under the steering column 20, and the lower legs are restrained between the steering column 20 and the floor 10. Even if this happens, it is possible to prevent an excessive compressive load from being applied to the driver's lower legs. That is, in the area in front of the driver's seat 16 on the floor 10, the aforementioned weakened portion 34 is present. Since the lower legs of the driver are formed between the steering column 20 and the floor 10, When the compressive load applied to the lower legs exceeds a predetermined value, one part of the floor 10 As shown in FIG. 4, the driver's heel is It is deformed downward and becomes depressed. From this, the driver's lower leg was partially damaged in Figure 1. It can move downwards as shown by the line, eliminating the constraint on the lower legs. can do. Therefore, even if the driver's lower legs become restrained as described above, , no excessive compressive load is applied to the lower legs, effectively protecting the driver's body. It will be possible.

0012 This invention is not limited to the one embodiment described above, and various modifications are possible. It is. For example, referring to FIGS. 5 and 6, variations of the fragile portion 34 are shown. Ru. In this modification, the fragile portion 34 is a part of the floor panel 26, that is, the A recess 38 is formed by driving into a rectangular shape in the area where the foot of the foot is located. The part of the floor stringer corresponding to No. 38 is cut out and is fragile. Although only one recess 38 is shown, these recesses 38 are designed to accommodate the driver's feet. There are two locations in the area.

[0013] Therefore, even if the weak part 34 of the modified example is located, the driver's lower leg may not be In a situation where the person is restrained, a portion of the floor 10 may become depressed starting from the vulnerable portion 34. This makes it possible to reduce the compressive load applied to the driver's lower legs. In addition, in Figure 6 , reference number 40 indicates a floor side member, and reference number 42 indicates a side sill. Furthermore, in the embodiment described above, there is a Although the weak part 34 is formed, a floor is formed in the front area of each seat other than the driver's seat 16. A 10 may be provided with a weak portion, respectively.

[0014]

[Effect of the idea]

As explained above, according to the car floor of this invention, the front area of the seat is For example, if the seat is the driver's seat, In the unlikely event that the driver's lower legs are caught between the floor and the steering column due to a collision, etc. Even if the driver is restrained due to the By recessing the lower part, the compressive load applied to the lower legs is reduced and the driver is protected. It has excellent advantages such as:
