Description

The present invention relates to a seat air conditioner.

Conventionally, in an in-vehicle seat air conditioner, a plurality of tubes connected to a first blower are arranged and integrated, and a first ventilation path and a plurality of tubes connected to a second blower are arranged and integrated. There is a second ventilation passage that is provided (for example, see Patent Document 1).

A plurality of outlets are formed in each of the first and second ventilation passages. The first and second ventilation passages are arranged between the surface of the seat pad of the seat and the skin so as to avoid the groove of the seat pad.

Specifically, the first ventilation passage is arranged on the front side of the groove of the surface of the seat pad in the vehicle traveling direction. The second ventilation passage is arranged on the rear side in the vehicle traveling direction with respect to the groove on the surface of the seat pad. The groove is a groove for fixing the outer skin to the seat pad, and is formed so as to extend in the vehicle width direction on the front surface side of the seat pad.

The airflow blown from the first and second blowers through the plurality of tubes in the first and second ventilation passages is blown into the vehicle compartment from the plurality of outlets, or is sucked from the vehicle interior through the plurality of outlets. Airflow is drawn into the first and second blowers through the plurality of tubes. As a result, air conditioning can be performed in a wide area on the front surface side of the seat pad.

Patent No. 4999455 Specification

In the seat air conditioner of Patent Document 1, as described above, when the groove extending in the vehicle width direction is formed in the seat pad 1, the first ventilation passage and the second ventilation passage are formed on the surface of the seat pad. It is placed avoiding. As a result, air conditioning can be performed in a wide area on the front surface side of the seat pad.

However, as an actual vehicle seat, in addition to the above-described seat pad having the groove extending in the width direction, seat pads 1A, 1B, and 1C shown in FIGS. 17A, 17B, and 17C are used.

In the seat pad 1A of FIG. 17A, grooves 2a and 2b extending in the vehicle traveling direction are formed on the surface of the seat pad 1A, and in three areas such as the side supports 3a and 3b and the main pad 4 arranged between the side supports 3a and 3b. It is divided.

In such a seat pad 1A, if the first and second ventilation passages of Patent Document 1 described above are arranged on the main pad 4 so as to avoid the grooves 2a and 2b, air conditioning can be performed by the main pad 4. Air conditioning cannot be performed by the side supports 3a and 3b.

In the seat pad 1B of FIG. 17B, in addition to the grooves 2a and 2b, a groove 2c that divides the main pad 4 into a region 4a on the front side in the vehicle traveling direction and a region 4b on the rear side in the vehicle traveling direction is provided.

Also in this case, if the first and second ventilation passages of Patent Document 1 are arranged in the regions 4a and 4b so as to avoid the groove 2c in the main pad 4, although air conditioning can be performed by the main pad 4, Air conditioning cannot be performed by the side supports 3a and 3b.

In the seat pad 1C of FIG. 17C, in addition to the grooves 2a and 2b, a groove 2c that divides the main pad 4 into an area 4a on the front side in the vehicle traveling direction, an area 4b on the rear side in the vehicle traveling direction, and an area 4c in the vehicle traveling direction center, 2d is provided.

Also in this case, in the main pad 4, the first ventilation passage of the above-mentioned Patent Document 1 is arranged in the region 4a of the main pad 4 on the front side in the vehicle traveling direction, and the second ventilation passage of the above-mentioned Patent Document 1 is included in the main pad 4. If it is arranged in the region 4b on the rear side in the vehicle traveling direction, the air conditioning can be performed in the regions 4a and 4b of the main pad 4, but the region 4c of the main pad 4 and the side supports 3a and 3b can perform the air conditioning. I can't.

As described above, the groove formed in the seat pad forms a region where air conditioning cannot be performed. Therefore, the region of the seat pad where the air conditioning can be performed is limited by the grooves 2a to 2d.

In view of the above points, an object of the present invention is to provide a seat air conditioner that enables air conditioning in a wide area on the surface of a seat pad.

The seat pad constituting the seat cushion 20 and the seat back 30 is made of an elastic member such as urethane foam.

The skin 50 is a sheet of air-permeable non-woven fabric or the like. The skin 50 is arranged so as to cover the surface 21 of the seat cushion 20.

The front surface 21a of the seat cushion 21 is provided with grooves 22a and 22b (see FIG. 2) which are recessed toward the back surface 21b. The grooves 22a and 22b are provided to fix the outer skin 50 to the seat cushion 20.

In the present embodiment, the plurality of first fixing fittings fixed to the outer skin 50 and the plurality of second fixing fittings fixed to the seat cushion 20 are connected by a connecting member. The plurality of first fixing fittings are arranged in the grooves 22a and 22b. The plurality of second fixing fittings are built in the seat cushion 20. A fixing structure for fixing the outer skin 50 to the seat cushion 20 using the first and second fixing fittings and the connecting member is well known.

As a result, the outer skin 50 is fixed to the seat cushion 21 in the grooves 22a and 22b by the first and second fixing fittings and the connecting member.

The grooves 22a and 22b are each formed so as to extend in the vehicle traveling direction. The grooves 22a and 22b are arranged at intervals in the vehicle width direction. The grooves 22a and 22b divide the surface 21a of the seat cushion 21 into three regions such as side supports 23a and 23b and a main pad 24.

The main pad 24 is arranged between the side supports 23a and 23b. As a result, the main pad 24 and the side supports 23a and 23b are arranged in the vehicle width direction (that is, the predetermined direction). Hereinafter, the main pad 24 and the side supports 23a and 23b are collectively referred to as regions 24, 23a and 23b.
