Vehicle seat provided with channel
A vehicle seat is provided with a channel, and includes a seat part provided with a channel formed on the lower surface thereof, wherein the channel is in communication with a seat surface; a back part connected to the seat part; a ventilation flow channel connected to at least the seat part and which is in communication with the channel; and a blower fan arranged in the ventilation flow channel. The vehicle seat is provided with a channel, and is configured such that the channel is formed on the lower surface of the seat part, thus preventing the deformation of the channel, maintaining a ventilation pathway to be intact even when a passenger is sitting on the seat for a long period of time, and enabling the passenger to constantly feel comfortable in the seat part.
1. A vehicle seat, comprising:
a seat part having a seat surface;
a channel defined in a lower surface of the seat part;
a back part connected to the seat part;
a ventilation flow channel connected to at least the seat part and configured to communicate with the channel;
a blower fan coupled to the ventilation flow channel; and
a leakage preventing pad in which an air inlet defined under the channel,
wherein a support protrusion configured to support a lower surface of the channel is formed on the leakage preventing pad,
wherein a leakage preventing wall in a shape corresponding to a shape of the channel is formed on the leakage preventing pad,
wherein the leakage preventing wall includes an adhesive surface being in contact with the lower surface of the channel, and an inclined plane which contacts a sidewall of the channel and is sloped to have an incline.
2. The vehicle seat of claim 1 , wherein the ventilation flow channel extends and connects to the back part.
3. The vehicle seat of claim 2 , wherein the blower fan is a first blower fan and is configured to blow air toward the seat part, the vehicle seat further comprising a second blower fan configured to blow air toward the back part.
4. The vehicle seat of claim 1 , further comprising one or more Positive Temperature Coefficients (PTCs) provided at the ventilation flow channel.
5. The vehicle seat of claim 1 , wherein one or more connection flow channels which communicate the channel with the seat surface are defined in the seat part.
6. The vehicle seat of claim 5 , wherein intervals between the support protrusions are arranged to be smaller than intervals between the connection flow channels.
7. The vehicle seat of claim 6 , wherein the support protrusions are formed in an elliptical shape having a first diameter greater than a diameter of each of the connection flow channels and a second diameter smaller than the diameter of each of the connection flow channels.
8. The vehicle seat of claim 1 , wherein the channel is formed as an H-channel.
9. The vehicle seat of claim 1 , wherein the channel is formed to have a cross section in a tetragonal shape, and one or more connection flow channels which communicate the channel with the seat surface are defined in the seat part.
10. The vehicle seat of claim 1 , wherein an adhesive member is mounted on a surface of an adhesive surface in contact with the channel.
11. The vehicle seat of claim 1 , wherein a pressure surface configured to deform and press an end portion of the sidewall extends from and is formed on an end of the inclined plane.
12. The vehicle seat of claim 1 , wherein a fixing part configured to press and be fixedly inserted into a middle portion of the sidewall is provided on an end of the inclined plane.
