Definitions
- the present invention relates to a vehicle seat.
- a typical conventional vehicle seat has a seat bottom and a seat back, and cushion means is attached to the seat bottom and the seat back.
- the cushion means is composed of an elastic body such as urethane and a zigzag panel, and has a function of elastically and comfortably supporting the weight of the user and a function of absorbing vibration during traveling of the vehicle.
- Patent Document 1 Japanese Patent Application Laid-Open No. H10-129322
- a large load is mainly absorbed by a zigzag panel provided on a seat bottom, and vibration during traveling is mainly absorbed by an elastic body.
- the conventional cushion means required both a zigzag panel and a thick elastic body.
- the zigzag panel absorbs a large load, it has to be large in radius, so it was necessary to secure enough space at the seat bottom for the zigzag panel to move. For this reason, the conventional seat bottom has a very large top and bottom thickness.
- FIG. 1 is a partially longitudinal side view of a vehicle seat according to the present invention.
- FIG. 2 is a side view of the shock absorbing mechanism of the present invention.
- FIG. 3 is an enlarged sectional view of the buffer mechanism.
- FIG. 4 is a graph showing the damping characteristics of a viscous damper of the shock absorbing mechanism and the damping characteristics of a conventional elastic body made of urethane tank.
- FIG. 5 is a partially longitudinal side view of a vehicle seat according to the present invention, in which a thin elastic body is attached to a movable plate.
- the vehicle seat 10 of the present invention has a seat bottom 11 and a seat back 12.
- the seat bottom 11 has a plate-shaped movable plate 13 and a base frame 14 attached to a vehicle body.
- the base frame 14 is preferably slidably mounted on the vehicle body.
- the front mounting portion 15 of the movable plate 13 is rotatably supported by a mounting shaft 16, and the mounting shaft 16 is mounted on a front rising bracket 17 of the base frame 14.
- the movable plate 13 is swingable about a mounting shaft 16.
- a buffer mechanism 18 is provided between the movable plate 13 and the base frame 14.
- the shock absorbing mechanism 18 includes an upper connector 21 which is fixed to the rear mounting portion 19 formed on the rear lower surface of the movable plate 13 by a shaft 20 and a rising bracket 22 formed on the upper surface of the base frame 14 by a shaft 23. With a lower connector 24 to be locked.
- the rising bracket 22 is positioned forward of the rear mounting portion 19 so that the length direction of the shock absorbing mechanism 18 matches the movement locus of the rear portion of the movable plate 13 as much as possible.
- the upper connector 21 has a rod 25 extending toward the lower connector 24.
- the rod 25 is inserted into a sleeve 26 of the lower connector 24, and a large-diameter stopper 27 is attached to the tip of the rod 25.
- a cylindrical member 28 having an inside diameter slightly larger than the inside diameter of the sleeve 26 is connected to the tip of the sleeve 26, and a cylinder chamber 29 is formed between the sleeve 26 and the rod 25.
- a stopper 30 is attached at the end of the tubular member 28, a stopper 30 is attached.
- the cylinder chamber 29 is filled with a viscous fluid D or a viscous fluid D having a force such as a viscous elastic fluid.
- 31 is a seal member.
- the rod 25 of the upper connector 21, the cylindrical member 28 of the lower connector 24, and the viscous body D constitute a viscous body damper 32.
- the buffer mechanism 18 has a spring 33 provided between the upper connector 21 and the lower connector 24.
- the panel 33 is arranged on the outer periphery of the viscous material damper 32. Panel 33 is movable Elastically supports the load applied to rate 13.
- the viscous body damper 32 When the rod 25 moves in the cylinder chamber 29 due to a load applied to the movable plate 13, the viscous body damper 32 attenuates vibration due to contact resistance between the viscous body D in the cylinder chamber 29 and the rod 25. .
- the viscosity of the viscous body D increases when the moving speed of the rod 25 is high, and decreases when the moving speed is low.
- the contact resistance increases and the damping force of the viscous body damper 32 increases, and when the moving speed of the rod 25 decreases, the contact resistance decreases and the viscous body damper decreases.
- the damping force of 32 also decreases.
- the viscous body damper 32 attenuates the moving speed of the rod 25 with a large resistance, and the panel load is reduced by a small load applied to the movable plate 13.
- the rod 33 is slightly compressed, the moving speed of the rod 25 is attenuated with a small resistance, so that the vertical vibration of the movable plate 13 is smoothly converged.
- the buffer mechanism 18 is preferably provided on each of the left and right sides of the movable plate 13.
- FIG. 4 shows a damping characteristic A of the viscous body damper 32 and a damping characteristic B of a conventional elastic body such as urethane foam attached to the seat bottom.
- the viscous material damper 32 has a damping characteristic substantially equal to that of the conventional elastic material.
- the plate-shaped movable plate 13 does not require a thick elastic body for absorbing an impact load, and as shown in FIG. 5, it is sufficient to attach the thin elastic body 04 to the movable plate 13 as necessary.
- the function of the buffer mechanism 18 can provide the user with sufficient comfort even with the thin elastic body 34.
- Reference numeral 35 denotes a cover sheet for the elastic body 34.
- a large load is mainly absorbed by a zigzag panel provided on a seat bottom, and vibration during traveling is mainly absorbed by an elastic body.
- the conventional cushion means required both a zigzag panel and a thick elastic body.
- the zigzag panel absorbs a large load, it has to be large in radius, so it was necessary to secure enough space at the seat bottom for the zigzag panel to move. For this reason, the conventional seat bottom was very thick.
- a large load is mainly absorbed by the panel 33, and vibrations during traveling are mainly absorbed by the viscous material damper 32.
- the elastic body, such as urethane, provided on the movable plate 13 can be made thin. This can be omitted together with the zigzag panel. Therefore, the thickness of the seat bottom is very thin, and the configuration of the seat bottom is simplified.
