Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a racing suit worn by a race driver, particularly a racing kart used in a four-wheeled vehicle race, and a driver wearing the racing suit. This invention relates to a device for safely securing the seat of a racing vehicle.

[Conventional technology]

In a four-wheeled vehicle race, the driver operating the racing car is exposed to extremely harsh and dangerous conditions due to frequent accelerations, large accelerations due to narling, etc., and high-speed driving at the limit. . Therefore, it is essential that the driver's body be secured to the racing car seat with a seat belt during the race.

Conventionally, this fixation has been applied to the driver's body while sitting in the seat.
This is done by tightening the seat belt using a point-type or five-point type seat belt.

[Problem to be solved by the invention]

However, since this seatbelt fixation involves directly tightening the seatbelt around the driver's body wearing a soft racing suit, the area of contact between the driver's body and the belt is small, and when subjected to intense acceleration or vibration, the belt gradually tightens against the driver's body. The problem was that it was very difficult for the driver to get stuck in the car.

Also, with conventional seatbelts, only a small part of the body, such as the shoulders and abdomen, is fixed, so it is difficult to handle severe loads such as acceleration and vibration. The burden had to be borne by a part of the body, and this was a considerable burden on the driver when racing cars had high horsepower and the race was long.

In addition, with such methods of fixing parts of the body, the driver is not completely fixed in the seat, resulting in poor hip fixation during deceleration, and centrifugal force changing the position of the driver's body relative to the seat when turning. This is an inconvenience, and in order to prevent this, the driver has to use his whole body to maintain his position, which has the disadvantage of making it difficult to concentrate on driving.

Therefore, an object of the present invention is to provide a new racing suit in order to solve the problems and drawbacks of the prior art and eliminate the above-mentioned inconveniences, and also to provide safety protection for the seats of race vehicles to be used with the new racing suit. The purpose is to provide a fixation device.

[Means to solve the problem]

In order to solve the above-mentioned problems of the prior art, the present invention arranges a rigid member equipped with a shock absorbing material inside a racing suit, and makes a fixing means such as a seat belt come into contact with the rigid part of the racing suit. It was to so. The rigid member may be placed throughout the racing suit so that it completely covers the driver's body,2 or the fastening means such as a seat belt may be placed only in the areas where force is applied. good.

[For production]

Since the fixing means such as the seat belt is brought into contact with the rigid part of the racing suit, the tightening force is applied to the rigid part of the racing suit and does not act directly on the driver's body. Therefore, it is possible to secure the seat to all the driver's seats with greater force than in the past, and it is also possible to use harder fixing means than in the past, which stabilizes the position of the driver's body while driving. Moreover, even if the seat is tightened with such a large force, the driver's body will not be unduly compressed.

〔Example〕

Next, the present invention will be explained using the drawings.

FIG. 1 is an overall side view showing one embodiment of the racing suit and safety fixing device of the present invention, and FIG. 2 is a sectional view of the main parts thereof. In the figure, 1 is a driver, 2 is a racing car seat, and 3 is a seat belt strap. In this case, the seat belt is of a two-point type, and the end of the seat belt is fixed to the seat or the vehicle body.

The seat 2 is molded from urethane foam or the like to fit the driver's body, and the driver 1 fits completely into the seat 2 and is secured by a seat hold 3. As the cross section of the racing suit 4 is shown in FIG. 2, the racing suit 4 includes a rigid member 6 under a suit outer material 5 made of a heat-resistant and flame-retardant material. The rigid member 6 can be made of, for example, flame-retardant plastic, carbon fiber, glass fiber, etc., and, like the seat 2, can of course be made to fit the body of the driver 1.
In this embodiment, the cover covers the driver's body all the way to his back.

Since this rigid member 6 has a certain degree of hardness, it functions as a protector.

On the outside and inside of the rigid member 6, shock absorbing materials 7a and 7b made of shock absorbing silicone resin such as norbothane and α-gel are pasted with adhesive or the like. This prevents vibrations from being transmitted directly to the driver. This shock absorbing material may be provided only on the inside of the driver 1, which is in contact with the body.

Although not shown in the figure, a similar rigid member 6 and shock absorbing materials 7a, 7b can be provided under the outer material of the racing suit at the waist and legs, if necessary. It is also possible to fix the entire driver's body to the seat 2.

As shown in FIGS. 1 and 2, the seat belt 3 contacts the rigid member 6 and tightens the rigid member 6t to fix the driver to the seat.

Unlike conventional seatbelts, which directly tighten the driver's body, there is no unnecessary pressure on the driver's body, or there is no possibility of the seat belt digging into the driver's body and causing pain.

Furthermore, the seat belt can be tightened more forcefully than before, making it possible to securely secure the driver.

Conventional seat belts can be used, for example, a five-point seat belt to secure the driver, but as in the present invention, the driver can be secured by tightening a rigid member built into the racing suit. In the case of the fixing method, the fixing is extremely firm, so basically, it is sufficient to fix the fixing device at one point using the two-point method shown in FIGS. 1 and 2. In addition, it becomes possible to select a material that is hard enough to hold as a seat belt material, and it becomes possible to develop a fixing means that goes beyond the conventional concept of seat belts.

FIG. 3 shows an embodiment of the rigid part, in which:
The rigid member is divided into a plurality of parts 6 as 6 b, 6 C, such as an upper body part, an abdominal part, and a waist part, in consideration of ease of putting on and taking off the racing suit. It is preferable that the divided rigid members 5a, 5b, and 6Ct are connected to each other by elastic members 8. This allows the back to expand and contract when walking, making it easier to walk, and also making it easier to enter the cockpit and assume a driving position.

The shape of the seat belt may be a full-length one as shown in FIG. 4, and the rigid member may be placed so as to correspond exactly to the seat belt that is passed from the shoulder to the abdomen. In this case as well, the end of the seat belt is fixed to the seat or the vehicle body.

Note that 9 is a small hole provided in the rigid member for ventilation, and can be provided as necessary. If necessary, it can also be provided in the shock absorbing material.

The rigid members divided into a plurality of parts may be integrally connected by providing a removable connecting means 10, and may be integrated so as not to come apart, especially in the lateral direction. This means that when some of the divided rigid members are fixed using fixing means such as seat belts, the tightening has the effect of preventing the divided parts to which no force is directly applied from becoming unstable. .

In the example described above, the rigid member was provided to cover the driver's back surface, but it goes without saying that depending on the situation, it may be sufficient to cover only the front surface, which is in contact with the fixing means such as the seat belt. Even in that case, the tightening force of the fixing means is received by the wide surface of the rigid member, and the tightening force is not directly applied to the driver's body.

Further, the fixing means is not limited to the seat belt, but any fixing means may be used as long as it abuts and engages with the rigid portion of the racing suit and fixes the driver to the seat.

〔Effect of the invention〕

As described above, in the present invention, a rigid member is arranged at a position corresponding to a fixing means such as a seat belt of a racing suit, and a tightening force is applied to this rigid member by the fixing means. When tightening seat belts, etc., no force is applied directly to the driver, and even if the driver is driving for long periods of time, the seat belt will not dig into the driver's body and cause pain to the driver.
Drivers do not lose their attention to driving by moving their bodies while driving to alleviate pain.

In addition, since it is tightened through a rigid member, the pressure receiving area is large and it is equipped with a shock absorbing material, so it can apply a greater force when tightening than a conventional seatbelt, enabling a stronger fixation and acceleration/deceleration. The driver's body is held in place extremely safely, without shifting position even when turning or turning.
