The position at which the air outlet member 40 is moved to the upper and outer ends of the shoulder opening of the seat back 2 is near the neck of the seated occupant with the highest seat height in the range in which the air blown from the air outlet 42a of the air outlet member 40 is assumed. It becomes an appropriate position to be blown toward.

図９〜１１に示す状態から送風口部材４０が、シートバック２の肩口の下内側に向けて移動されると、送風口部材４０はベース部材３０に対して上述とは反対方向に移動して、送風口部材４０の送風口４２ａから送風される空気が比較的座高の低い着座乗員の首付近に向けて送風されるのに適切な位置となるように調整される。そして、送風口部材４０がシートバック２の肩口の下内側端に達すると、図６〜８に示すように、送風口部材４０の第１当接面４０ｂ及び第２当接面４０ｃは、ベース部材３０の第１当接面３０ｂ及び第２当接面３０ｃに当接する。この状態では、送風口部材４０の送風口４２ａから送風される空気が、想定される範囲で最も座高の低い着座乗員の首付近に向けて送風されるのに適切な位置となる。   When the air outlet member 40 is moved toward the lower inner side of the shoulder opening of the seat back 2 from the state illustrated in FIGS. 9 to 11, the air outlet member 40 is moved in the opposite direction to the base member 30. The air blown from the blower opening 42a of the blower opening member 40 is adjusted so as to be in an appropriate position for blowing air toward the neck of the seated occupant having a relatively low seat height. When the air blowing member 40 reaches the lower inner end of the shoulder opening of the seat back 2, the first contact surface 40b and the second contact surface 40c of the air blowing member 40 are formed on the base as shown in FIGS. The member 30 contacts the first contact surface 30b and the second contact surface 30c. In this state, the air blown from the blower port 42a of the blower port member 40 is in an appropriate position to be blown toward the neck of the seated occupant having the lowest seat height in the assumed range.

図１２は、上述のように調整される送風口部材４０の送風口４２ａからの送風方向の軌跡Ｔをシート１に着座した乗員の体との関係で示す。図１２のように、送風口４２ａからの送風方向の軌跡Ｔは、シートバック２の肩口の上外側から下内側の範囲で傾斜して形成される。そのため、体格の大きい乗員Ｐｌに対しても、体格の小さい乗員Ｐｓに対しても、それぞれの首付近に向けて送風を行うことができる。   FIG. 12 shows the trajectory T in the air blowing direction from the air outlet 42a of the air outlet member 40 adjusted as described above in relation to the body of the occupant seated on the seat 1. As shown in FIG. 12, the trajectory T in the blowing direction from the blower opening 42 a is formed to be inclined in the range from the upper outer side to the lower inner side of the shoulder opening of the seat back 2. Therefore, it is possible to blow air toward the vicinity of the neck of both the occupant Pl having a large physique and the occupant Ps having a small physique.

以上のように、送風方向の調整のため、送風口部材４０は、一つの回転軸４０ｄによってベース部材３０に対して回動される。そのため、回転軸を２軸とされたもの、若しくは自在継手を採用したものに比べて送風口周りの構造を簡素化し、装置を小型化することができる。   As described above, the air blowing member 40 is rotated with respect to the base member 30 by the single rotating shaft 40d for adjusting the air blowing direction. Therefore, the structure around the air blowing port can be simplified and the apparatus can be downsized as compared with a structure in which the rotation shaft is two axes or a structure that employs a universal joint.

また、送風口部材４０の回動時、送風口部材４０のスライド面４０ａは、ベース部材３０のスライド面３０ａに対して、常時接近した対向状態とすることができ、ベース部材３０と送風口部材４０の一体感を得ることができる。   Further, when the blower port member 40 is rotated, the slide surface 40a of the blower port member 40 can be in an opposed state that is always close to the slide surface 30a of the base member 30, and the base member 30 and the blower port member. Forty sense of unity can be obtained.

更に、ベース部材３０に対する送風口部材４０の回動端部において、ベース部材３０と送風口部材４０の各当接面３０ｂ、４０ｂ、３０ｃ、４０ｃが互いに当接するため、その位置を送風口部材４０のベース部材３０に対する格納位置として見栄え良く送風口部材４０を格納することができる。   Further, since the contact surfaces 30b, 40b, 30c, and 40c of the base member 30 and the air blowing member 40 are in contact with each other at the rotating end of the air blowing member 40 with respect to the base member 30, the position of the air blowing member 40 is determined. It is possible to store the air outlet member 40 with a good appearance as a storage position for the base member 30.

更にまた、送風口部材４０による送風方向がシートバック２の肩口の下内側端部とされた状態において、ベース部材３０及び送風口部材４０のスライド面３０ａ、４０ａ、第１当接面３０ｂ、４０ｂ、及び第２当接面３０ｃ、４０ｃが線対称を成すように、ベース部材３０と送風口部材４０との間の各境界面が形成されている。そのため、送風口部材４０による送風方向がシートバック２の肩口の下内側端部とされた状態において、ベース部材３０と送風口部材４０との各境界面を線対称の意匠性に優れた線で見せることができ、装置の意匠性を向上することができる。   Furthermore, in the state where the air blowing direction by the air blowing member 40 is the lower inner end portion of the shoulder opening of the seat back 2, the slide surfaces 30a, 40a, the first contact surfaces 30b, 40b of the base member 30 and the air blowing member 40 are provided. In addition, each boundary surface between the base member 30 and the air outlet member 40 is formed so that the second contact surfaces 30c and 40c are line-symmetric. Therefore, in the state in which the air blowing direction by the air blowing member 40 is the lower inner end of the shoulder opening of the seat back 2, each boundary surface between the base member 30 and the air blowing member 40 is a line excellent in axisymmetric design. The design of the apparatus can be improved.

以上、特定の実施形態について説明したが、本発明は、それらの外観、構成に限定されず、本発明の要旨を変更しない範囲で種々の変更、追加、削除が可能である。例えば、上記実施形態では、送風口部材４０をシート１の左右両側の肩口に設けたが、いずれか一方のみとしてもよい。また、上記実施形態では、本発明を自動車のシートに適用した例を示したが、飛行機、船、電車等に搭載のシートに適用することもできる。   As mentioned above, although specific embodiment was described, this invention is not limited to those external appearances and structures, A various change, addition, and deletion are possible in the range which does not change the summary of this invention. For example, in the said embodiment, although the ventilation port member 40 was provided in the shoulder opening of the left-right both sides of the sheet | seat 1, it is good also as only either one. Moreover, although the example which applied this invention to the seat of the motor vehicle was shown in the said embodiment, it can also be applied to the seat mounted in an airplane, a ship, a train, etc.
