Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat structure excellent in waterproofness and cushioning property, which is used in small boats and the like.

[0002]

2. Description of the Related Art Conventionally, there are some small boats such as jet propulsion boats gliding on the water which are provided with a seat made of a cushion body, but these are often wet by splashes of water or rain when sailing. .. And the cushion material of the seat, in order to exert good cushioning properties,
Air is exhausted by receiving a compressive force, and the air is sucked in at the time of restoration, but water is also sucked in at the time of inhaling this air. In order to prevent this, for example, in Japanese Utility Model Publication No. 53-24799, a cushion material is sealed with a skin and an air bag is connected,
It proposes a structure in which the air discharged by the compression force is sent into the air bag so that the outside air is not sucked.

[0003]

In the above structure, the air bag and the recess for enclosing the air bag are largely projected to the lower side of the seat, which causes a space below the seat to be a dead space. In order to reduce the dead space, it is conceivable to thin the entire cushion material, but doing so may impair the cushioning property.

The present invention has been made in order to eliminate the above-mentioned conventional drawbacks, and makes the seat exhibit a good cushioning property, and the space under the seat becomes a dead space due to the arrangement of the airbag. The purpose of the present invention is to provide a seat structure for a small boat or the like.

[0005]

According to the present invention, an outer surface of a cushioning material is covered with a bottom plate and an outer skin in a watertight structure to form a cushioning body, and a recessed portion opening downward is formed in the bottom plate. An airbag, at least a part of which is located in the recess, is provided, an opening is formed in the bottom plate, and the opening of the airbag is connected to the opening.

[0006]

In the above structure, since the outer surface of the cushion material is covered with the bottom plate and the outer cover in a watertight structure and is connected to the airbag, the air only reciprocates between the cushion and the outside. Intake of water from the air bag is prevented, and since at least a part of the airbag is located inside the recessed part provided in the bottom plate, a cushioning material can be wrapped around the side of the airbag to create a good cushion for the seat. The performance can be exhibited, and the space below the seat does not become a dead space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, a hull member 1 constituting a ship bottom plate.
1 and the deck member 12 constituting the deck are FR
The hull 1 is configured integrally with P and the like and is joined to each other at the peripheral edge portion 13 to configure the hull 1. A seat 3 is formed on the center line of the hull 1 on the rear side of the center of the deck, and both sides of the seat 3 are recessed to form a foot deck 4.
The outer side is further raised to form a gun flannel 5. The seat 3 is a deck member 1 between the foot decks 4.
2 includes a seat base 6 formed by standing upright, a base member 62 installed on the seat base 6, and a cushion body 30 installed on the base member 62. The operation handle 2 installed on the handle base 60 is provided on the front side of the seat 3, and a person sitting on the seat 3 puts his foot on the foot deck 4 and grips the operation handle 2 to drive.

The sheet 3 is formed as shown in FIGS. That is, the cushion material 31 formed in a predetermined shape with urethane foam or the like is covered with the outer cover (waterproof cover) 32 made of a vinyl sheet or the like, and the bottom plate 33 is arranged on the lower surface of the cushion material 31. The outer surface is covered with a watertight structure to form a cushion body 30. The bottom plate 33 has a flange 37 protruding downward at its peripheral portion.
In addition, a flat recess 38 that opens downward is formed in the central portion, and a front wall 34 that rises upward and walls 39 that extend forward from both side portions are formed in the front portion. Further, three openings 35 are formed in the recess 38 of the bottom plate 33 in the longitudinal direction. A flat air bag 7 made of vinyl or the like is arranged in the recess 38, and the opening 3 is also formed in the air bag 7.
5, three openings 75 are formed corresponding to each of the openings 3.
5 and 75 are connected to each other and fixed by the band 70.

A cushion body 30 is provided on the seat base 6.
A base member 62 for adjusting the inclination of is seated, and the base member 62 is attached to the upper surface of the seat base 6 by an appropriate fixing means (not shown). Then, the airbag 7 and the bottom plate 33 in the recess 38 are placed on the base member 62, and the bottom plate 37 is fixed to the base member 62 by mounting screws 64. The space 69 below the seat base 6 is used as a storage case, and its outlet is provided at an appropriate position (not shown).

In the above embodiment, the airbag 7 is the seat 3
The figure shows the shape when no one is sitting on it. When a person sits on the seat 3, the airbag 7 is inflated, and the airbag 7 is inflated so as to be pressed against the bottom plate 33 and the base member 62. In addition, the airbag 7
The seat 3 may be in a state in which a person is not sitting on the seat 3 and there is almost no internal volume (completely collapsed). Further, in the above-described embodiment, the airbag 7 is wholly located in the recess 38 both in a state where air is in and out, but only a portion is located in the recess 38 and May be projected downward from the bottom plate 33, or only a part of or the whole of the airbag 7 may be recessed 38 only when the air is in or out of the airbag 7. It may be located inside.

The lower portion of the cushion body 30 may be constructed as shown in FIGS. 6 and 7. That is, the plate-shaped base member 67 is attached to the lower surface of the bottom plate 33 via the packing 66 to form the watertight recess 38.
Further, the openings 35 are formed at the lower portions of the two persons 15 who are seated on the cushion body 30 to promote the circulation of air by the pressurization. See also FIG.
As shown by the phantom line, the opening 35 may be arranged at the intermediate portion between them. Further, as shown in FIG. 8, a storage compartment 68 is integrally formed on the upper portion of the seat base 6, the bottom plate 33 is attached to the upper surface of the storage compartment 68 via the packing 66, and a part of the storage compartment 68 is positioned in the recess 38. When the bag 7 is positioned above the storage case 68 and the airbag 7 is inflated, the recess 38 and the storage box 68 are shown as indicated by an imaginary line.
You may make it bulge in.

In the above structure, a person sits on the seat 3, puts his / her foot on the foot deck 4, grips the operation handle 2, and drives the hull 1 to run. At this time, the compression force is applied to the cushion body 30 from above, whereby the air in the cushion material 31 is discharged into the airbag 7, and when the compression force is released, the air in the airbag 7 is transferred into the cushion material 31. By being returned, and repeating such an action, good cushioning properties are exhibited. In addition, while the seat 3 is often splashed with water while sailing, as described above, the air always reciprocates between the cushion material 31 and the airbag 7, and does not suck in air from the outside. Water is reliably prevented from entering the cushion material 31.

Further, in the above structure, the airbag 7 is housed in the recess 38, and the recess 38 is sealed at its peripheral edge, so that the intrusion of water into the recess 38 is reliably prevented. Further, since the airbag 7 has a flat shape and does not project downward, the space 69 below the cushion body 30 can be used as a storage case or the like. Further airbag 7
Is extended in the longitudinal direction of the seat 3, so that compared with the case where the airbag is provided only in the central portion of the seat 3,
It is possible to suppress the amount of protrusion to the lower side of the seat. When the amount of downward projection is small, there is an advantage that the layout of the engine becomes easy in the case where the engine is located below the seat.

[0014]

As described above, according to the present invention, the outer surface of the cushioning material is covered with the bottom plate and the outer cover in a watertight structure, and this is connected to the air bag, so that the air is connected to the air bag. Just make a round trip between
Intake of water from the outside is prevented, and water is reliably prevented from entering the cushion material. Further, since at least a part of the airbag is located in the recessed portion provided in the bottom plate, it is possible to cause the seat to exhibit good cushioning properties by wrapping the cushion material around the side of the airbag. The space below the cushion body does not become a dead space, and this space can be used as a storage case.
