In addition, the seat cushion SC is divided into five sections, for example, at approximately equal intervals in the front-rear direction of the automobile, and the respective sections are displayed as C1, C2, C3, C4, and C5 from the rear side of the automobile. ing.

本実施形態では、シートバックSBを6区分、シートクッションSCを5区分しているが、少なくとも3区分に区分すればよく、例えば4区分にすることもできる。
図1に示すシートバックSBの背凭れ面におけるそれぞれの区分B1〜B6は、自動車における下から順に、着座者の身体部位の骨盤部、腰部、背中部、肩甲骨部、肩部、首部に相当するものとし、また、シートクッションSCの着座面におけるそれぞれの区分C1〜C5は、自動車における後方側(シートバック側)から着座者の身体部位の臀部後半、臀部前半、大腿部後半、大腿部前半、膝裏部に相当するものとして、以下説明する。
In the present embodiment, the seat back SB is divided into six sections and the seat cushion SC is divided into five sections. However, it may be divided into at least three sections, for example, four sections.
The sections B1 to B6 on the back surface of the seat back SB shown in FIG. 1 correspond to the pelvis, waist, back, scapula, shoulder, and neck of the body part of the seated person in order from the bottom in the car. In addition, each of the sections C1 to C5 on the seating surface of the seat cushion SC includes the rear half (seat back side) of the automobile from the rear half of the buttocks, the first half of the hip, the second half of the thigh, and the thigh. The following description will be made on the assumption that the front half corresponds to the back of the knee.

送風シートにあっては、通常、ブロワー等の送風手段(図示しない)がシートバックSBあるいはシートクッションSCに設けられ、この送風手段からの空気が、シートバックSBやシートクッションSCに形成された送風路を介してシートバックSBの背凭れ面やシートクッションSCの着座面、ひいてはそれらの外部に向けて送出される。
そして、図1に示すシートにあっては、送風手段からの空気を背凭れ面の外部に送り出すシートバックSBにおける送風域を、シートバックSBの背凭れ面を自動車の上下方向で6区分に区分したうちの着座者の肩部位に相当する区分B5に限定的に特定すると共に、送風手段からの空気を着座者の外部に送り出すシートクッションSCにおける送風域を、シートクッションSCの着座面を前後方向で5区分に区分したうちの着座者の大腿部後半部位に相当する区分C3に限定的に特定し、これら特定の送風域に対してのみ直接的に送風するものとしている。
なお、このような送風域の特定は、送風手段からの空気の流通される送風路の送風口4a、9aを所定の送風域、つまりシートバックSB、シートクッションSCにおいて特定した区分に整列させて限定的に設けることにより行われ、この送風路の送風口は、例えば、特定した区分内の複数個所にそれぞれ設けられる。
In the blower sheet, a blower (not shown) such as a blower is usually provided in the seat back SB or the seat cushion SC, and air from the blower is blown in the seat back SB or the seat cushion SC. It is sent through the road toward the back surface of the seat back SB, the seating surface of the seat cushion SC, and eventually to the outside thereof.
In the seat shown in FIG. 1, the air blowing area in the seat back SB for sending air from the air blowing means to the outside of the backrest surface is divided into six sections in the vertical direction of the automobile. The section B5 corresponding to the shoulder portion of the seated person is limited to the section B5, and the air blowing area in the seat cushion SC for sending the air from the blowing means to the outside of the seated person is set in the front-rear direction. The section C3 is limited to the section C3 corresponding to the latter half of the thigh of the seated person, and the air is blown directly only to these specific blowing areas.
The air blowing area is specified by aligning the air outlets 4a and 9a of the air passage through which the air from the air blowing means is circulated in a predetermined air blowing area, that is, the section specified in the seat back SB and the seat cushion SC. For example, the air outlets of the air passages are provided at a plurality of locations in the specified section.

図2に示すように、シートバックSBにあっては、送風手段に連通する送風路4が、例えば、シートバックSBのパッド材3内に形成され、その送風口4aが背凭れ面、つまり通気性のある表皮材1に向けて開口されている。また同様に、図3に示すように、シートクッションSCにあっては、送風手段に連通する送風路9が、例えばシートクッションSCのパッド材8内に形成され、その送風口9aが着座面、つまり通気性のある表皮材6に向けて開口されている。
ここでは、シートバックSBにおける着座者の肩部位に相当する区分を区分B5の一区分として説明しているが、区分B5を含む範囲であれば足り、区分B5だけでなく、上下の区分B6,B4の少なくともいずれかの区分に渉ることも可能であり、また、区分は等間隔に限定されず、区分B5を他の区分より上下方向に幅広にすることもできる。
同様に、シートクッションSCにおける着座者の大腿部後半部位に相当する区分を区分C3の一区として説明しているが、区分C3を含む範囲であれば足り、区分C3だけではなく、前後の区分C4,C2の少なくともいずれかの区分に渉ることも可能であり、また、区分は等間隔に限定されず、区分C3を他の区分より前後方向に幅広にすることもできる。
As shown in FIG. 2, in the seat back SB, the air passage 4 communicating with the air blowing means is formed in, for example, the pad material 3 of the seat back SB, and the air blowing port 4a is the backrest surface, that is, the ventilation. It opens toward the skin material 1 with the property. Similarly, as shown in FIG. 3, in the seat cushion SC, the air passage 9 communicating with the air blowing means is formed in, for example, the pad material 8 of the seat cushion SC, and the air blowing port 9a is a seating surface. That is, it opens toward the skin material 6 with air permeability.
Here, the section corresponding to the shoulder portion of the seated person in the seat back SB is described as one section of the section B5. However, the section including the section B5 is sufficient, and not only the section B5 but also the upper and lower sections B6, B6. It is possible to intervene in at least one of the sections of B4, and the sections are not limited to equal intervals, and the section B5 can be wider in the vertical direction than the other sections.
Similarly, the section corresponding to the latter half of the thigh of the seat occupant in the seat cushion SC is described as one section of the section C3, but the range including the section C3 is sufficient, and not only the section C3 but also the front and rear It is possible to intervene in at least one of the sections C4 and C2, and the section is not limited to an equal interval, and the section C3 can be wider in the front-rear direction than the other sections.

なお、送風手段(ブロワー)は、着座者の操作により電源がON状態となる構成でも、着座者が着座した際、自動的に電源がON状態となる構成であってもよい。また、所定時間、若しくは所定温度となった際には、自動的に電源がOFFとなる設定にできる構成としてもよい。 Note that the air blowing means (blower) may be configured such that the power is turned on by the seated person's operation, or the power is automatically turned on when the seated person is seated. Alternatively, the power may be automatically turned off when a predetermined time or a predetermined temperature is reached.

このシートバックSBの肩部に相当する区分B5、腰部に相当する区分B2、およびシートクッションSCの大腿部後半に相当する区分C3が送風効果の高い部位であることは、本願発明者等の鋭意研究開発の成果として導き出されており、他の部位への送風を伴わなくても着座者の快適性が十分に得られることが判明している。
つまり、この発明によれば、着座者に対する送風効果が高いとされるシートバックSBの肩部相当部位(区分B5)と腰部相当部位(区分B2)、シートクッションSCの大腿部後半相当部位(区分C3)のみを送風域として特定し、この送風域のみへ送風するだけで着座者に対する送風効果を得るため、着座者の快適性を損なうことがなく、送風域の範囲が減少するから、消費電力の大幅な削減が図られる。
The section B5 corresponding to the shoulder of the seat back SB, the section B2 corresponding to the waist, and the section C3 corresponding to the rear thigh of the seat cushion SC are parts having a high blowing effect. It has been derived as a result of earnest research and development, and it has been found that sufficient comfort for the seated person can be obtained without blowing air to other parts.
That is, according to the present invention, the shoulder equivalent part (section B5) and the waist equivalent part (section B2) of the seat back SB, which are considered to have a high air blowing effect on the seated person, and the thigh latter part equivalent part of the seat cushion SC ( Since only the classification C3) is specified as the air blowing area, and the air blowing effect for the seated person is obtained only by sending air to only the air blowing area, the comfort of the seated person is not impaired, and the range of the air blowing area is reduced. Electric power can be greatly reduced.

上記の実施形態においては、シートバックSBの肩部に相当する区分B5、又は腰部に相当する区分B2の少なくともいずれか、およびシートクッションSCの大腿部後半に相当する区分C3に限定的に送風するものとして具体化しているが、これに限定されず、例えば、シートバックSB、シートクッションSCのいずれか一方のみの送風域に限定的に送風する構成としてもよい。このシートバックSB、シートクッションSCのいずれかのみの構成においても、着座者に対する送風効果が高いとされる部位への送風により、着座者の快適性を損なうことがなく、送風域の範囲が減少するから、消費電力の大幅な削減が図られるという効果が得られる。 In the above embodiment, air is limited to at least one of the section B5 corresponding to the shoulder portion of the seat back SB or the section B2 corresponding to the waist portion, and the section C3 corresponding to the rear thigh portion of the seat cushion SC. However, the present invention is not limited to this. For example, a configuration may be adopted in which the air is limited to the air blowing area of only one of the seat back SB and the seat cushion SC. Even in the configuration of only the seat back SB and the seat cushion SC, the air blowing to the portion where the air blowing effect for the seated person is high does not impair the comfort of the seated person, and the range of the air blowing area is reduced. As a result, the power consumption can be greatly reduced.

このように、本発明によれば、シートバックSBの肩部に相当する区分B5、腰部に相当する区分B2,およびシートクッションSCの大腿部後半に相当する区分C3の送風効果の高いことに着目し、これらの送風効果の高い部位にのみ直接的な送風域とするため、着座者の快適性を損なうことがなく、消費電力の大幅な削減が図られ、送風域の範囲が減少するから、消費電力の大幅な削減が図られるという効果が得られる。 Thus, according to the present invention, the air blowing effect is high in the section B5 corresponding to the shoulder portion of the seat back SB, the section B2 corresponding to the waist, and the section C3 corresponding to the rear thigh of the seat cushion SC. Paying attention to these direct air blowing areas only in areas where the air blowing effect is high will not impair the comfort of the seated person, resulting in a significant reduction in power consumption and a reduction in the air blowing area. As a result, the power consumption can be greatly reduced.

上記実施形態で空気の送風として説明しているが、冷風を送風することもでき、かかる場合はブロワーに代えて冷却装置を設ければよい。 Although described as air blowing in the above embodiment, it is possible to blow cold air. In such a case, a cooling device may be provided instead of the blower.

ここで、シートバックSBの背凭れ面およびシートクッションSCの着座面に着座した着座者の身体が送風口4a、9aに密着した場合、着座者の身体が送風路の送風口を塞いでしまい、送風路4,9からの空気の円滑な送出が妨げられるおそれがある。そこで、図2,3に示すように、送風口4a、9aから送り出された空気を平面方向、つまりシートバックSBの背凭れ面、シートクッションSCの着座面に沿った方向に通気するための通気層5、7を、送風路の送風口と着座者、例えば表皮材1,6との間に配設することが好ましい。この種の通気層5,7としては、例えばシートバックSBでの背凭れ面(B1〜B6)の全面、シートクッションSCでの着座面(C1〜C5)の全面に渡る非通気性素材からなる袋体5a、7a内に平面方向での空気の流通可能な可撓性のある立体部材5b、7bを内設した平面状の通気用スペーサーが利用でき、この通気層内を流動する空気は、袋体の表皮材1,6側に設けられた通気口5c、7cを介して、着座者方向の外部に放出され、これにより送風域への空気の円滑な送風が確保できる。なお、この通気口5c、7cは、着座者の着座によっても塞がれない位置を含めて形成することが必要となる。 Here, when the body of the seated person seated on the seat back surface of the seat back SB and the seating surface of the seat cushion SC is in close contact with the air outlets 4a and 9a, the body of the seated person blocks the air outlet of the air passage, There is a possibility that smooth air delivery from the air passages 4 and 9 may be hindered. Therefore, as shown in FIGS. 2 and 3, ventilation for aerating the air sent out from the air blowing ports 4a and 9a in the plane direction, that is, the direction along the seat back surface of the seat back SB and the seating surface of the seat cushion SC. The layers 5 and 7 are preferably disposed between the air outlet of the air passage and the seated person, for example, the skin materials 1 and 6. The air-permeable layers 5 and 7 of this type are made of, for example, a non-breathable material over the entire back surface (B1 to B6) of the seat back SB and the entire seating surface (C1 to C5) of the seat cushion SC. A planar ventilation spacer in which flexible three-dimensional members 5b and 7b capable of circulating air in a plane direction can be used in the bags 5a and 7a. Air flowing in the ventilation layer can be used as follows: The air is discharged to the outside in the direction of the seated person through the vents 5c and 7c provided on the skin material 1 and 6 side of the bag body, thereby ensuring smooth blowing of air to the blowing area. In addition, it is necessary to form these vent holes 5c and 7c including a position that is not blocked by the seating of the seated person.

このように、送風路の送風口4a、9aと着座者との間に通気層(通気用スペーサー)5,7を設けることで、シートバックSBの背凭れ面あるいはシートクッションSCの着座面に着座者が密着した場合であっても、送風路の送風口から送り出された空気は通気層を介して流通し、着座者による閉塞の免れた通気口5c、7cからの放出を伴って流動するため、送風手段からの空気の円滑な流通が確保できるから、着座者の快適性は一層向上される。 As described above, the ventilation layers (ventilation spacers) 5 and 7 are provided between the ventilation openings 4a and 9a of the air passage and the seated person, so that they can be seated on the seat back surface of the seat back SB or the seat cushion SC. Even if the person is in close contact, the air sent out from the air outlet of the air passage flows through the vent layer and flows with the release from the vent holes 5c and 7c, which are free from obstruction by the seated person. Since the smooth circulation of air from the air blowing means can be ensured, the comfort of the seated person is further improved.

ここでは、通気層5,7を、送風路の送風口4a、9aと表皮材1,6との間に配設した通気用スペーサーとして例示しているが、この通気層は送風路の送風口と着座者との間に介在されれば足りるため、表皮材の表面側(着座者側)に通気層を設ける構成としてもよい。
また、通気層5,7として通気用スペーサーを例示しているが、送風路の送風口4a、9aから送り出された空気を平面方向に流通可能とする構成であればよく、例えばパッド材表面、あるいは表皮材表面を凹凸状とし、この凹凸の隙間を空気の流通する通気層としてもよい。
Here, although the ventilation layers 5 and 7 are illustrated as ventilation spacers arranged between the ventilation ports 4a and 9a of the ventilation path and the skin materials 1 and 6, this ventilation layer is the ventilation opening of the ventilation path. Therefore, a ventilation layer may be provided on the surface side (seat side) of the skin material.
Moreover, although the ventilation spacer is illustrated as the ventilation layers 5 and 7, it should just be the structure which can distribute | circulate the air sent out from the ventilation openings 4a and 9a of a ventilation path in a plane direction, for example, a pad material surface, Alternatively, the surface of the skin material may be irregular, and the gap between the irregularities may be a ventilation layer through which air flows.
