Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seat for a vehicle, such as a motorcycle, on which an occupant rides in a straddling position.

Seats for this type of motorcycle have a structure in which a cushion material molded into a predetermined size and shape is covered with a seat skin. There is no adjustment function to compensate for this, and for some people, the ride quality and seat comfort may deteriorate.
There were cases where the riding position became unstable.

The present invention was made based on these circumstances, and
The shape of the seating area can be freely adjusted according to the occupant's physique and preferences, providing a good riding posture.
Improves ride comfort and seating comfort, and also has air chamber 1.
For riding type vehicles that require a small amount of air to be supplied to the cabin 7
- The purpose is to provide

That is, in order to achieve the above object, the present invention forms a plurality of air chambers in the seating portion of the sorting skin covering the outside of the cushioning material, communicates the air chambers with an air pressure adjustment section, and controls the air by the air adjustment section. The seating portion is bulged out and its shape changed by adjusting and controlling the air pressure in the room.

An embodiment of the present invention will be described below based on drawings in which the present invention is applied to a motorcycle.

In the diagram, 1 is the frame, 2 is the front fork, 3 is the front wheel,
4 indicates the fuel tank, 5 indicates the engine, and 6° indicates the rear wheels. A seat 7 according to the present invention is located behind the fuel tank 4.
is installed. This seat 7 has a front seat part 8 and a rear seat part 9.
A driver A is seated on the front seat part 8, and a fellow passenger is seated on the rear seat part 9, straddling each other. In such a seat 7, a cushioning material 11 made of urethane foam or the like is attached to a seat bottom plate 10 made of synthetic resin, and the outer periphery of this cushioning material 11 is covered with a seat skin 12 made of vinyl leather or the like.
It is covered with.

The cushioning material 11 becomes wider toward the rear of the front seat part 8, and is integrally formed in a stepped shape such that the rear seat part 9 is located higher than the front seat part 8. Waist support part 1 whose brace part holds driver A's waist brace
3'L, @formed. A large number of flat cavities 15 are formed between the upper seating portion of the seat skin 12 and the lumbar rest portion 13 and the front cover 14 attached to the back side thereof. A hexagonal pattern is formed on the abutment part 13. Each empty space 15 accommodates a nozzle I6 made of soft urethane foam or the like, and this nozzle 16 is adhered to one side of the seat cover 12. In addition, the seat bottom plate 10 and Each hose 19 passes through the cushion material 11.
are inserted and hermetically welded, and these empty spaces 1
5 constitutes an air chamber 20 that is inflated by supplying air, as shown by the imaginary line in FIG. The hoses 19 are each communicated with an air pressure adjustment section 21. The air pressure adjustment unit 21 of this embodiment utilizes the air pressure adjustment mechanism of the front fork 2 and the shock absorber 22 for suspension of the rear wheel 6, and the front fork 2 and the shock absorber 22 are connected to the solenoid valves 23 and 22, respectively. , are connected to a motor-driven air pump 25 via a check valve 24. And this check valve 24
The hoses 19 are connected to the downstream side of the hoses 19 through a three-way joint 26 and a solenoid valve 27, and the solenoid valves 27 are opened and closed by a controller (not shown).
Pressurized air is individually supplied to each air chamber 2o by an air pump 25.

Note that the reference numeral 28 is an exhaust valve, and the reference numeral 29 is a sensor that detects air pressure.

According to such a configuration, when the controller is operated while seated on the seat 7 and pressurized air is supplied and discharged into each air chamber 20, the front seat portion 8 is adjusted according to the air pressure within the air chamber 20. Since the amount of bulge on both sides of the front end central portion 18 and the lumbar rest portion 13 changes, the shape of the seating portion of the front seat portion 8 can be freely changed. Therefore, it is possible to not only accommodate the preferences of driver A, but also to compensate for variations in physique, providing a good seating posture for many drivers A, and improving seat comfort and riding comfort. can be done.

In particular, as in this embodiment, the front end central portion 1 of the front seat portion 8 is
8 and the shape of the waist rest part J3 can be adjusted to prevent the driver A from sliding forward when seated, and also to hold the waist part so as to wrap it from the front and back, improving the holdability and seating feeling. ) has the advantage of being good.

In addition, since the air chamber 2O beam is provided on the seat skin 12 outside the John material 11, there is no need to deform the cushion material 11 when the air chamber 2Q expands, and the air chamber 2Q does not need to be deformed locally in the seating area. Since it is divided, only a small amount of air is needed to be supplied to each room, and the shape of the seating area can be changed in a short period of time.

Note that the air pressure adjustment section is not limited to the above-mentioned embodiment; for example, as shown by the imaginary lines in FIG. In addition, the number and position of the air chambers are not specified in the embodiment.

Furthermore, the vehicle according to the present invention is not limited to a motorcycle, but may also be a tricycle or a snowmobile.

In short, it is applicable to all vehicles in which a passenger rides astride.

According to the present invention described in detail above, a plurality of air chambers are provided in the seating portion of the seat skin, and the shape of the seating portion can be freely changed by adjusting and controlling the air pressure in the air chambers. Of course, we can respond to your preferences,
It is possible to compensate for variations in body physique, provide a good and stable seating posture for many occupants, and improve seat comfort and ride comfort. In addition, since the air chamber is provided in the seat skin outside the cushioning material, there is no need to deform the cushioning material when the air chamber inflates, and the resistance during inflation is therefore reduced, allowing the air to be supplied to each chamber. It has the advantage of requiring only a small amount.
