Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an antistatic sheet that prevents static electricity from accumulating on the clothes of vehicle occupants.

When an occupant's clothing rubs against the seat surface due to vehicle vibrations, static electricity is generated on the clothing, and when the passenger touches a door handle when getting on or off the vehicle, the static electricity is discharged all at once, causing discomfort. The voltage of this static electricity is approximately 20KV during dry winter.
This is especially true when wearing nylon, silk, or woolen clothing.

To prevent this, it is necessary to release the static electricity generated on clothing to the vehicle body, but installing special equipment or wiring for this purpose requires space and spoils the appearance.

The present invention attempts to solve the above-mentioned problem by making the vehicle seat itself conductive and sequentially discharging static electricity generated on the clothing of the occupant to the vehicle body through the seat.

That is, the antistatic sheet of the present invention has conductive fibers incorporated into the member constituting the surface of the sheet, and the fibers are connected to a vehicle pod.

Hereinafter, the present invention will be explained with reference to illustrated embodiments.

In the vehicle seat 1 shown in FIGS. 1 and 2, the surface of the seat cushion is made of cloth.

The fabric has two conductive fibers in the parts that come into contact with the occupant's body.
is incorporated. The figure is a schematic representation, and the conductive fibers 2 are woven at an appropriate density in the defect to ensure a sufficient contact area. As the conductive fiber 2, conductive fibers such as thin metal wires, metal-plated fibers, or secondary fibers can be used.

3 is a ground wire, one end of which is bolted to a leg 4 on which the seat 1 is slid. The other end is connected to the woven conductive fiber 2. The legs 4 are integrated with the vehicle podium by a rail (not shown) and are electrically connected.

When a seat with such a structure is used, the occupant's clothing comes into contact with the conductive fiber 2 and the ground wire 3.
It is grounded to the vehicle podium via . Therefore, even if static electricity is generated on clothing due to vibrations while driving or friction when getting on and off the vehicle, it is discharged to the vehicle body one after another and does not become charged, and is discharged all at once to the door handles etc. when getting on and off the vehicle. You won't feel any discomfort.

In this example, in order to suppress the voltage due to static charges generated per unit time to several hundred V or less, the weaving density of the conductive fiber 2 is adjusted so that the resistance value between the passenger and the vehicle podium is 10 MΩ or less. It is preferable to consider.

In this way, the anti-static sheet of the present invention has 4t fibers woven into the fabric that makes up the seat surface, and by grounding the fibers to the vehicle podium, static electricity generated on the occupant's clothing can be quickly discharged to the vehicle podium. It is something that forces you to do something.

Furthermore, since the present invention has thin conductive fibers woven into the fabric of the sheet at an appropriate density, no base material is required and the appearance is not impaired.

In the above example, conductive fibers are directly attached to the fabric of the sheet.
J) However, it may be woven into the fabric of the seat cover, or if it is not made of fabric, a method other than weaving may be used.

Additionally, conductive fibers may be woven not only into the seat cushion but also into the seat pack or both.

As stated above, the anti-static seat of the present invention incorporates conductive fibers into the members constituting the seat surface, and the fibers are grounded to the vehicle body to prevent static electricity from accumulating on the clothes of the occupants. It does not spoil the appearance of Sea-F.
