The present invention relates to a two-way blower motor for a vehicle seat, which may provide high wind pressure and high wind discharge characteristics to greatly improve the performance of the blower motor. The two-way blower motor for a vehicle seat according to the present invention comprises: an upper housing (10) which has an air inlet port (11) and dual-sided upper air outlet units (12 and 12'); a lower housing (20) which has dual-sided lower air outlet units (22 and 22'); a hub (41) which is rotated by a driving motor (30) installed in an inner space of the lower housing (20); and a fan (40) which is integrally installed around the outer periphery of the hub (41). A plurality of auxiliary blades (43) inclined outward are installed at a certain interval on the outer perimeter surface (41A) of the hub (41), so that air absorbed through the air inlet port (11) is pushed and guided firstly toward a curved portion (42A) of each of the blades (42) by the auxiliary blades (43) when the driving motor (30) is driven. The absorbed air guided toward the curved portion (42A) of each of the blades (42) is guided secondly by the curved portion (42A) along second and third air outlet passages (S2 and S3), so that the air can be emitted through dual-sided air outlet ports (10A and 20A).

    본 발명에 따른 블로워 모터는 공기 흡입구(11) 및 양측 상부 공기 배출부(12)(12')를 가지는 상부 하우징(10)과; 양측 하부 공기 배출부(22)(22')를 가지는 하부 하우징(20)과; 상기 하부 하우징(20)의 내부 공간에 설치된 구동모터(30)에 의해 회전하는 허브(41)와; 상기 허브(41)의 외측 둘레에 일체로 설치된 팬(40);을 포함하고, 상기 허브(41)의 외측 둘레면(41A)에 외측으로 경사진 형상의 보조 블레이드(43)를 일정 간격을 두고 복수 개로 설치하여 상기 구동모터(30)가 구동될 때 상기 보조 블레이드(43)에 의하여 공기 흡입구(11)를 통해 흡입된 공기를 1차적으로 블레이드(42) 각각의 만곡부(42A) 측으로 밀어내면서 안내시키고, 블레이드(42) 각각의 만곡부(42A) 측으로 안내되는 흡입 공기를 만곡부(42A)에 의하여 2차적으로 제2 및 제3 공기 배출 통로(S2)(S3)를 따라 안내 유도시키면서 양측 공기 배출구(10A)(20A)로 배출시키는 것을 특징으로 한다.
