Description

  The present invention relates to an automobile seat. More specifically, the present invention relates to an automobile seat suitable for a sports car, a dress-up car, a competition automobile, and the like.

  Automobile seats such as sports cars, dress-up cars, and competition cars are designed to be lightweight and highly safe for the purpose of improving driving operations. The main body is fixed, and the seat main body is composed of a seat rail (mounting bracket) having a slide function that can finely adjust the front and rear and up and down.

  In order to enhance the versatility of this seat rail for a plurality of vehicle types, a method of arranging two pairs on both sides of the lower surface portion of the seat body in parallel in the front-rear direction, the outer dimension of the rail mounting portion of the seat body is According to the average shape of the sheet body, the range of 380 mm to 450 mm is ideal. Conventionally, the seat body has not been specifically designed for each vehicle type, and mounting to a vehicle has been realized by designing the seat rail mounting bracket for each vehicle type.

However, this installation method places restrictions on the installation space of the seat body,
It is originally ideal for cars with low body heights and for competition, and it is impossible to secure a space for lowering the center of gravity of the human body and lowering the seat mounting position for the purpose of stabilizing the running of the car, There is a problem that the positional relationship with the steering wheel during driving cannot be easily attached to an ideal position.

  Therefore, the present invention solves the above-mentioned problems, and when the seat body and the seat rail are attached, the outer size of the conventional completed seat body is reduced, and the seat body and the seat rail are simultaneously designed, thereby allowing a plurality of designs. An object of the present invention is to provide a seat for an automobile that secures a mounting space for the above vehicle types and is comfortable to sit on.

  In order to achieve the above object, the present invention provides two seat rails that support the seat body movably in the front-rear direction on the left and right sides of the lower surface portion of the seat body integrally formed with a seat portion and a backrest. In a sports car automobile seat arranged, the seat portion of the seat body is curved upward so as to substantially match the shape of the driver's buttocks, and the left and right sides of the lower surface portion of the seat portion generated thereby A sports car automobile seat characterized in that a recess is formed in the space, and two seat rails are arranged in the recess in accordance with the outer dimensions of the width of the seat portion of the seat body.

  The outer size of the seat is conventionally 380mm to 450mm, but the average of the driver's waist is 70 to 95cm, the outer size is set to 390mm to 400mm, and the seat rail is arranged in the width to make it compact. Can be planned. The seat rail can slide the seat body back and forth 20 to 25 cm, and can be used for fine adjustment of the top and bottom.

  Since the seat for the automobile according to the present invention is formed to be curved upward so that the shape of the seat matches the shape of the butt using a cushioning material, the seating state is extremely excellent in fit to the human body, By arranging the seat rail in a small space generated by curving the seat, the outside dimension of the seat is set to a narrower range than before, making the seat compact for sports. When changing to a higher seat, it can be easily attached to the preferred location of the person using it. In addition, the mounting state is improved aesthetically, and the fashionability of the car is improved. Moreover, since the position of the seat can be set according to the preference of the person who sits down, the elements that get tired are reduced, and a comfortable sitting comfort can be obtained.

  Hereinafter, examples of embodiments of the present invention will be described with reference to the drawings. 1 is a side view showing an example of an embodiment of an automobile seat according to the present invention, FIG. 2 is a rear view thereof, FIG. 3 is an enlarged view of a rear surface of a seat portion in FIG. 2, and FIG. FIG. 5 is a perspective view of the front surface of the seat. FIG. 6 is a perspective view of one of the seat rails, and FIG. 7 is a conventional automobile seat. 1 to 7, 1 is a seat body, 2 is a backrest, 3 is a seat, and the seat 3 is curved upward so as to fit the driver's buttocks H.

  FIG. 1 shows a state in which a seat body (bucket type) 1 is attached to a seat rail 5, and a side stay 6 is used as a mounting bracket. The seat body 1 is seated by the driver, and the part that hits the body is formed by covering with sponge, urethane, etc. as a cushion with cloth, leather, etc. The shape of the back surface 2 of the sheet main body 1 is formed integrally with a tough material such as glass fiber, carbon kevlar material, epoxy material, and the like so that the body can be easily operated and the body is not shaken. The back surface 2 of the sheet body can also be made stronger with metal.

  The bracket that attaches the seat body 1 to the vehicle body is configured based on a seat rail 5 that can slide back and forth between 20 cm and 25 cm in order to cope with differences in height and physique when attached to a car. 4 and FIG. 6, the upper rail 5a is attached to the seat body 1 and the lower rail 5b is fixed to the floor of the automobile. As the seat rail, a commonly used seat rail can be used. FIG. 1 shows a side surface of the seat rail in a mounted state, FIG. 2 shows a rear surface of the seat rail, and FIG.

A bracket for attaching the seat body, that is, the side stay 6 is arranged and fixed on the upper rail 5a, and the upper rail 5a and the lower rail 5b are slidably fitted. With the side stay 6, the seat body is attached to the floor of the automobile so as to be movable back and forth. Further, by selecting a plurality of holes 10 (three steps in FIGS. 1 and 6) provided in the side stay 6, the height of the seat and the angle of the backrest of the seat body can be finely adjusted. In order to ensure the stability of the seat body, it is desirable that the contact surfaces of the side stay 6 and the seat portion 3 have at least 70 cm ² on one side.

  As shown in FIG. 4, the left and right lower rails are connected by a connecting arm 7, and four points are fixed to the floor of the automobile by a fixing stay 9, and the upper rail is connected by a slide positioning operation lever 8. The material of the seat rail is metal because it must be strong to protect the human body from accidents.

  In the present invention, the outer dimension W (FIG. 2) of the width of the seat portion 3 of the seat body is 70 cm to 95 cm in average for the driver's waist with respect to the conventional range of 380 mm to 450 mm (FIG. 7). In the above, the outer dimension assumed from the inner dimension is set to 390 mm to 400 mm (FIG. 2), and the seat rail is inserted into both the left and right sides of the seat part 3 where the driver's hip H corresponds as shown in FIG. The widths of the two seat rails were adjusted within this outer dimension by designing and molding together with the seat body. In other words, the size required for the lateral width of the conventional seat rail is reduced, the degree of freedom of the portion where the seat rail is attached is increased, and the seat body can also be made compact. Incidentally, the dimension angle (height and width of the rail cross section) of the seat rail itself is assumed to be 15 mm to 40 mm.

  As illustrated in FIG. 2 and FIG. 3, the seat portion of the seat body is curved according to the shape of the driver's bottom portion H (two-dot chain line), so that the fit of the seated state of the driver is achieved. With such a shape of the seat portion, a space is formed on both the left and right sides of the lower surface portion 3a behind the seat portion, so that the seat rail 5 can be disposed in the space. In addition, like the example of illustration, the hollow 3b can be formed in the space of both sides, and the seat rail 5 can also be arrange | positioned in the hollow 3b. With such a configuration of the seat portion, it is possible to prevent the body from moving even in response to a severe behavior of an automobile such as a sudden brake, and it is possible to drive accurately. The shape of the seat is desirably as close as possible to the buttocks H. However, in order to be able to cope with drivers having different physiques, a larger design shape may be used as long as it is spatially permitted. However, it is necessary for the seat rail to be within the side edges of the lower surface portion of the seat body of the automobile seat according to the present invention.

  Alternatively, the seat body can be directly attached to the slide rail (upper rail) without using this side stay. The connection method can be selected from these two types depending on the type of vehicle to be attached. In order to reduce the weight of the side stay, it is preferable to use various metals such as aluminum and titanium among the metals.

  The automobile seat according to the present invention can be used as a fashion because the degree of freedom of the seating position is increased, the appearance attached to the automobile is beautiful, and the fashion factor is increased. It can be widely used by changing the design and changing the size and shape of the seat body so that it can cope with differences in height and physique, for example.
