Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pillow which is attached to a headrest of an automobile seat and supports an occupant's head.

[0002]

2. Description of the Related Art Conventionally, as a pillow to be attached to a headrest of an automobile seat, Japanese Patent Application Laid-Open No. 9-15466 discloses a pillow.
No. 6 publication. This pillow is formed with a curved concave surface on the surface in contact with the occupant's head.The head is embraced by the concave to prevent the occupant's neck from tilting to the left and right. It is also designed to prevent fatigue and stiff shoulders.

[0003] The above-mentioned pillows do not have a function of warming or cooling the head merely by supporting the occupant's head.
During the hot summer months, the occupants' heads and necks become sweaty and uncomfortable even if the vehicle is air-conditioned, and in the cold winter months, the seats are cold immediately after sitting down, The passengers were not comfortable in the car due to the problem of not getting warm.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a pillow for an automobile which supports the head of an occupant sitting on an automobile seat and can adjust the temperature to a comfortable level. It is.

[0005]

SUMMARY OF THE INVENTION According to the present invention,
In a car pillow attached to a headrest of a car seat and supporting an occupant's head, a controller for setting a temperature is attached to the pillow, and the controller connected to a Peltier element for cooling and heating air is connected to a cigar socket by a cord. The pillow is connected to the pillow so that it can be cooled and heated.

According to a second aspect of the present invention, the Peltier device is housed in a space inside a pillow.

According to a third aspect of the present invention, the Peltier device is arranged at a position separated from the pillow.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. As shown in FIG. 1, the pillow 4 of the present invention is attached to a headrest 2 of an automobile seat 1 by a belt 3 to support an occupant's head,
As shown in FIG. 2, the pillow 4 is provided inside a cloth bag 5 having good air permeability, in addition to an elastic material 6 such as a sponge which is flexible and elastic and has good air permeability, and sweat, body odor and odor of indoor occupants. Charcoal 7 such as Bincho charcoal, white charcoal, black charcoal, etc. and a magnetic field line with a far-infrared effect that promotes blood circulation, acting on the back of the head, improve blood circulation, eliminate shoulder stiffness and recover fatigue. It contains both or one of the contributing permanent magnets 8.

The pillow 4 further has a suction port 9 for sucking air into the inside and a controller 10 on its side. The controller 10 has a temperature setting switch 11, a microcomputer (not shown) and an internal battery, and The plug 13 at the tip is inserted into a cigar socket (not shown) to supply electric current from the battery of the vehicle. As shown in FIG. A Peltier element 16 connected to the controller 10 is housed, and when current is supplied to the controller 10, the air inside the vehicle is discharged from the suction port 9 by the rotation of the blower fan 15 to the space 14 of the pillow 4.
The pillow 4 can be heated or cooled by sucking air and passing through the Peltier element 16 to the entire inside of the pillow 4.

The Peltier device 16 is a device in which an N-type semiconductor and a P-type semiconductor are joined between a positive electrode and a negative electrode with a metal piece. When a DC current is passed from the N-type semiconductor to the P-type semiconductor, the current flows in the N-type semiconductor. In the P-type semiconductor, heat is transferred in the forward direction in the opposite direction, and the metal piece is cooled to lower the temperature, and the temperature rises when the direction of conduction is reversed.

Therefore, when the pillow 4 is used, when the plug 13 is inserted into the cigar socket and the switch 11 of the controller 10 is operated to the cold side, the blower fan 15 is rotated, and the air inside the vehicle is sucked through the suction port 9 so as to suck the cigar socket. Current from the car battery through the Peltier device 1
6, the space 14 is cooled and the cooled air flows to the cloth bag 5 containing the elastic material 6, the charcoal 7, and the permanent magnet 8, and the entire pillow 4 is cooled. You. When the switch 11 is operated to the heat side, the space 14
The inside of the pillow begins to generate heat, and the entire pillow 4 is heated.

In the above embodiment, the Peltier element is accommodated inside the pillow. However, the case accommodating the Peltier element may be accommodated in a lower portion of a seat or the like, and the case and the pillow may be connected by a cord. By arranging the case at a position away from the pillow in this way, the vibration of the blower fan is not transmitted to the pillow.

[0013]

According to the present invention, in a pillow for an automobile mounted on a headrest of an automobile seat and supporting a head of an occupant, a controller for setting a temperature is attached to the pillow, and a Peltier element for cooling and heating air. The controller was connected to a cigar socket by a cord to enable cooling and heating of the pillow. Therefore, if the current is supplied through the cigarette socket, it is possible to cool and heat only the occupant's head separately from the temperature control in the vehicle by using the Peltier element, thereby making the occupant a comfortable environment. .

Further, if the Peltier element is housed in the space inside the pillow as in claim 2, the occupant's head can be cooled and heated only by attaching the pillow to the seat back.

Further, if the Peltier element is arranged at a position separated from the pillow, vibration of the pillow can be prevented.
