Abstract

PURPOSE:To improve the rigidity of a rear seat and to ensure its head clearance of passengers, by constituting the rear seat of a rack-shaped seat surface part, continued to a floor part, and a vertically rising wall-shaped back-leaning part and forming the seat surface part to an almost spherical shape being recessed to the bottom. CONSTITUTION:A rear seat 6 is constituted of a rack-shaped seat surface part 6a, continued of a floor part 5, further of a vertically rising wall-shaped back- leaning part 6b continued to said seat surface part 6a, and it is formed in an almost spherical shape being recessed to the bottom. Consequently, the rear seat substantially improves its rigidity by spherical surface tension as compared with that of flat plate shape in the past. While the improvement of this regidity eliminates the necessity for forming a conventional rugged bead part or the like in the seat surface part 6a. Accordingly, a cushion material can be directly mounted through no seat frame, and a low seating position of passengers is attained from point of lowering the upper surface position of a cushion and forming the seat surface part 6a being recessed to the bottom, thus a head clearance can be ensured by that amount of the lower seating position of the passengers.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a synthetic wood BFJ having a so-called bathtub-shaped lower body formed integrally with an upright wall around the periphery of a floor portion.
This article relates to the structure of the rear seats of manufactured military bodies, and in particular to improving the rigidity of the seat surface and securing the so-called head clearance.

[Conventional technology]

Conventionally, in sheet metal car bodies, in order to ensure the rigidity of the rear seat part, for example, uneven beads are formed on the flat rear seat part, and on the other hand, to ensure stiffness, for example, the rear seat frame is made separately. At the same time, a structure is adopted in which cushioning is provided on the frame.

By the way, recently, synthetic resin car bodies have been manufactured that are integrally molded using synthetic resins such as fiber reinforced resin (hereinafter referred to as FRP), but in this FRP car body, it is necessary to ensure the rigidity and cushioning properties of the rear seat part. In order to achieve this, it is conceivable to adopt a bead shape like the above-mentioned sheet metal car body and a structure for placing the kutsushiran material.

[Problem that the invention seeks to solve]

However, forming uneven edges in the rear seat portion of an FRP vehicle body reduces molding efficiency and causes an increase in costs. In addition, in order to maintain overall rigidity and reduce tearing, FRP car bodies generally adopt an approximately egg-shaped shell structure, and like the sheet metal car body mentioned above, a separate frame is used for the seat surface. If a cushion material is placed on top of this, the seating position of the occupant will be raised, making it difficult to ensure head clearance.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a rear seat structure in which the rigidity can be increased as well as the head clearance of the occupant by 6'α in a synthetic resin vehicle body.

[Means for solving problems]

The present invention provides a synthetic resin vehicle body in which a standing wall is formed around the periphery of a floor part, in which the rear seat is comprised of a shelf-shaped seat part that continues to the floor part, and a standing wall-shaped backrest part that continues to the seat part. The seat is characterized in that the seat portion is formed into a substantially spherical shape with a downward concave shape.

[Function] In the rear seat structure according to the present invention, since the seat portion is formed into a substantially spherical shape, its rigidity is greatly improved compared to the conventional planar shape. In addition, due to this improved rigidity, there is no longer a need to form uneven bead parts on the seat surface as in the past, so the cushion material can be placed directly without going through the seat frame, and the top surface of the cushion can be placed at a lower position. Because of the low point and the fact that the seat surface is concave downward! The seating positions of J and M are lowered, making it easier to ensure head clearance.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 to 3 are diagrams for explaining a rear seat structure of a vehicle body according to an embodiment of the present invention.

In the figure, 1 is a car to which the structure of this embodiment is applied, and the car body 2 of the car 1 has a lower body 3 and an upper body 4.
It is composed of. This upper body 4 is formed by adhering an inner panel to the inner surface of an outer panel, and its lower peripheral edge is inserted and fixed into the upper peripheral edge of the lower body 3.

The lower body 3 is of a so-called bathtub type, in which a standing wall 5a is integrally formed on the periphery of a floor portion 5. At the rear of the lower body 3 is a rear seat 6 for two people.
The six rear seats 6 are integrally formed with left and right seat portions 6a which are integrally formed in the shape of a shelf following the floor portion 5, and left and right seat portions 6a which are integrally formed in the shape of a substantially upright wall. , and a right backrest portion 6b. These left and right seat portions 6a
is formed into a substantially spherical shape concave downward, and the left and right backrest portions 6b are formed concave toward the rear of the vehicle. In other words, the rear seat 6 is formed with a depression having a shape corresponding to the body of the occupant.

Further, a cushion material 8 for absorbing impact from the road surface is directly adhered onto the seat portion 6a and the backrest portion 6b. Note that 7 is a luggage storage section that is integrally formed following the backrest section 6b, and an engine is disposed below the luggage storage section 7.

Next, the effects of this embodiment will be explained.

In the structure of this embodiment, the seat surface portion 6a of the rear seat 6 is formed into a substantially spherical shape, so that the tension of the spherical surface of this portion increases (improves) its rigidity compared to the conventional flat plate shape.

In addition, since the seat portion 6a is recessed downward and the improved rigidity eliminates the need for the uneven bead portion for reinforcement on the cough seat portion 6a, a cushion member 8 is provided on the seat portion 6a.
Since the passenger can be directly attached, the seating position of the passenger is lowered, making it easier to secure head clearance (■).

Furthermore, since the seat surface portion 6a and the backrest portion 6b are formed in a concave shape downward and rearward, respectively, the occupant's waist and back portion are securely held by the concave portions as shown by broken lines in FIG. 3, resulting in a feeling of holding. , it can improve the fit.

In the above embodiment, the backrest portion 6b was also formed in a concave shape, but in the present invention, the backrest portion does not necessarily have to be formed in a concave shape, and even in this case, it is possible to improve the rigidity of the seat portion and ensure head clearance. The effect of facilitating this can be obtained.

〔Effect of the invention〕

As described above, according to the rear seat structure of a synthetic resin vehicle body according to the present invention, the seat surface of the rear seat is formed into a substantially spherical shape concave downward, so that it is not necessary to form an uneven bead etc. as in the conventional case. This has the effect of improving the rigidity of the rear seat, and since the seat surface is concave downward, the seating position of the occupant is lowered accordingly, ensuring head clearance.
