Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle seat suitable for use as a vehicle seat in, for example, a railway vehicle. More specifically, it will be explained in detail with a base frame attached to a leg portion fixed on a floor of a passenger compartment. A vehicle in which a seat main body is supported, the seat main body is supported by the base frame, the seat main body is provided with a seat cushion and a seat back erected on a rear end side thereof, and a pair of left and right armrests is provided on both sides of the seat main body. For seats.

2. Description of the Related Art For a bench seat used as a vehicle seat for a train or the like, the seating direction on the seat can be arbitrarily selected according to the traveling direction of the train, or the preference or demand of a seated person. A turn-around structure has been adopted.

That is, generally, as shown in FIG. 6, in a vehicle seat 1, a base frame 3 is supported by legs 2 fixed on the floor surface of a vehicle compartment, and a rotation adjusting mechanism is mounted on the base frame 3. A seat body 6 is supported via 5 so as to be rotationally adjustable. The seat body 6 is provided with a seat cushion 7 and a seat back 8 provided upright on the rear end side thereof, and a pair of left and right armrests 9 are provided on both sides of the seat body 6.

As a reclining mechanism for tilting the seat back 8 of the seat body 6 back and forth, a gas lock mechanism having a gas cylinder and a piston rod is used, and one end of the gas lock mechanism is attached to the seat cushion 7 side. It is known to attach the other end side to the seat back 8 side.

Further, as shown in FIG. 6, a heater member 10 for heating passengers and the inside of the vehicle is attached to the lower surface side of the base frame 3, or as shown by a dotted line, the vehicle compartment floor below the seat cushion 7 of the seat body 6. It is installed on the surface. Further, as shown in FIG. 6, the electric wiring 4 for the heater member 10 is largely exposed from the seat body 6.

[0006]

Since the heater member 10 of the conventional vehicle seat 1 is mounted on the lower side of the base frame 3 or on the floor of the passenger compartment below the seat cushion 7. However, it is difficult to place luggage under the seat cushion 7 and to secure a sufficient space for the seat occupants of the rear seat to put their feet because the heater member 10 becomes an obstacle, and cleaning below the seat cushion 7 is difficult. It was difficult to do. Also, hook the luggage or legs on the electric wiring 4 for the heater member 10 that is largely exposed,
It was dangerous and there was a risk that an accident such as a short circuit would occur.

An object of the present invention is to provide a sufficient space under the seat body for placing luggage and feet when the heater member is installed below the seat body and to clean the seat cushion below. To facilitate
Another object of the present invention is to provide a vehicular seat that prevents the electric wiring for the heater member from being exposed to a large extent and prevents the electric wiring from catching a baggage or a foot and causing an accident such as an electric leakage.

[0008]

The present invention has been made in view of the above-mentioned problems, and a base frame is supported by legs fixed to the floor surface of a vehicle compartment, and a seat body is attached to the base frame. In a vehicle seat in which the seat body is supported, the seat cushion includes a seat cushion and a seat back provided upright on a rear end side of the seat body, and a pair of left and right armrests is provided on both sides of the seat body. Is supported in a cantilever manner, and heater members are attached along the front and rear outer portions in the longitudinal direction of the base frame.

[0009]

According to the present invention, the base frame is cantilevered by the legs fixed to the floor surface of the passenger compartment, the seat body is supported by the base frame, and the front and rear outer portions in the longitudinal direction of the base frame. Since the heater member is installed along the seat, it is possible to secure enough space below the seat cushion of the seat body to put luggage and feet, and it is possible to easily clean the bottom part of the seat body. Further, it is possible to prevent the electric wiring for the heater member from being largely exposed, and to prevent an accident such as a leakage of electricity by catching a baggage or a foot on the electric wiring.
