Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger car, a commercial vehicle,
The present invention relates to a structure of a seat in a vehicle such as a bus. 2. Description of the Related Art In a seat of a vehicle as described above, in a pad member constituting a seat portion or a backrest portion of the seat, a ventilation passage reaching the surface of the pad member is formed in the pad member.
There is a configuration in which air (hot air, cold air, or normal-temperature air) from an air blower provided on the back side of the pad member is supplied to the air passage of the pad member. Thereby, the air blown by the air blower flows from the air passage of the pad member to the occupant seated on the seat through the skin covered by the pad member, and the occupant seated on the seat has high comfort. When the air passage is formed in the pad member as described above, an air passage for connecting the air passage of the pad member and the air blower is required. In this case, for example, JP-A-10-
As disclosed in Japanese Patent No. 276859, a duct or tube-shaped air passage is formed of synthetic resin, and the air passage is connected to the air passage of the pad member and the air blower. is there. [0004] According to the structure described in the prior art, since a ventilation path is provided separately from the pad member and the ventilation device, the production cost of the ventilation path can be reduced. There is room for improvement in terms of aspects. Further, if a duct-like or tube-like ventilation path is to be formed of a synthetic resin as in the structure described in the related art, a mold for producing the ventilation path is required. Thereby, for example, when the specification of the seat is changed and the position of the air passage of the pad member is changed,
It is necessary to change the shape of the blowing path, and accordingly, it is necessary to change the mold for producing the blowing path (it is necessary to prepare a new mold for producing the blowing path). According to the present invention, there is provided a vehicle seat structure in which an air passage is formed in a pad member constituting a seat portion or a backrest portion of a seat and an air passage is provided for connecting the air passage of the pad member and an air blower. It is another object of the present invention to reduce the production cost of the air passage and to appropriately cope with a specification change in which the position of the air passage of the pad member is changed. According to a first aspect of the present invention, there is provided a pad member constituting a seat portion or a backrest portion of a seat, wherein a blower penetrating through the front surface and the back surface of the pad member. When the passage is formed in the pad member, a thin sheet member (or thin plate member) having no air permeability is applied to the back surface of the pad member, and a predetermined portion of the sheet member (or plate member) is connected to the back surface of the pad member. By doing so, a ventilation path is formed between the sheet member (or plate-shaped member) and the back surface of the pad member, and the ventilation of the ventilation device is supplied to the ventilation path of the pad member via the ventilation path. are doing. [0007] In the structure described in the prior art, all parts of the air passage are formed in a duct shape or a tube shape by a synthetic resin separate from the pad member. According to the first feature, the air passage is constituted by the sheet member (or plate-like member) and the back surface of the pad member, and the back surface of the pad member is also used as a part of the air passage. [0008] As in the structure described in the prior art, all parts of the air passage are formed in a duct shape or a tube shape by a synthetic resin separate from the pad member.
When the back surface of the pad member is used also as a part of the airflow path, the sheet member (or plate member) can be brought closer to the back surface of the pad member by that amount. Accordingly, the protrusion of the sheet member (or the plate-like member) from the back surface of the pad member can be reduced. [II] According to the feature of claim 1, the sheet member (or plate-like member) is applied to the back surface of the pad member,
By connecting a predetermined portion of the sheet member (or plate-shaped member) to the back surface of the pad member, an air flow path is formed between the sheet member (or plate-shaped member) and the back surface of the pad member. Thus, according to the first aspect of the present invention, the sheet member (or the plate member) connected to the back surface of the pad member.
By changing a predetermined portion of the pad member, the shape and arrangement of the air passage can be relatively easily changed. By changing a predetermined portion of the sheet member (or the plate-shaped member) connected to the back surface of the member, the shape, arrangement, and the like of the airflow path can be set appropriately. Therefore, according to the features of the first aspect, as in the structure described in the related art, it is possible to say that the production mold of the ventilation path is changed in response to a change in specification in which the position of the ventilation path of the pad member is changed. There is no need to do anything (like preparing a mold for the production of a new ventilation path). FIG. 1 shows the seats (driver's seat and passenger seat) of a passenger car. The seat is provided with a seat 1, a backrest 2 and a headrest 3. A pad member 4 made of urethane foam or the like is prepared, and the surface of the pad member 4 is covered with a skin 5 made of cloth (or made of vinyl leather or leather), and an adhesive is applied to substantially the entire surface of the pad member 4.
