Abstract: A bi-directional blower includes a blower body for guiding for air to flow along an entire circumference scroll shape of an inner space of the blower body. The blower body divides the inner space into an upward space and a downward space to guide air flow. The blower body comprises: an upper discharge case discharging the air flow along the entire circumference scroll shape toward the upward space through an upper discharge port; and a lower discharge case discharging the air flow along the entire circumference scroll shape toward the downward space through a lower discharge port.

Abstract: A bidirectional blower may include a blower body having a scroll rib making a length of an entire perimeter scroll guiding air flow in an internal space to an outlet end portion where air discharge is performed, and a fan in which a blade having an inlet angle of an acute angle and an outlet angle of an obtuse angle draws external air into the internal air, thereby realizing the characteristics of lowering an operating noise by preventing a generation of vortex while enhancing air volume performance suitable for a ventilation seat.

Abstract: A release actuator for a vehicle seat includes a spur gear that is rotatable in one direction or in the other direction by receiving rotational force from a motor, and has sliding grooves that are formed in both surfaces of the spur gear and have a predetermined length. A first cable guide is disposed to face one surface of the spur gear and has a protrusion placed in one of the sliding grooves. The first cable guide is connected to a first cable that withdraws a walk-in latch and releases walk-in lock when the first cable is pulled. A second cable guide is disposed to face the other surface of the spur gear, has a protrusion placed in the other sliding groove, and is connected to a second cable that withdraws a folder lock latch and releases folder lock when the second cable is pulled.

Abstract: A ventilation seat for a vehicle is provided. The ventilation seat is configured such that a through channel to directly discharge air is formed in a seat pad so that air supplied from an air supply unit is discharged over the seat pad through the through channel, whereby the through channel or the like can be prevented from becoming narrow or being blocked due to the weight of an occupant, resulting in increased or maximize air discharge rate.

Abstract: A leg rest apparatus is provided. A leg rest panel is configured to be adjusted between a deployed position and a stored position. The apparatus includes a lift link that articulates a rear end and a front end rotatably coupled to the seat and the leg rest panel, respectively. A link base with a rear end fixed to the seat is separated from the lift link and a front end is disposed toward a front side of the seat. A front guide link with a front end and a rear end is rotatably connected to a first coupling portion of the leg rest panel and the link base, respectively. A rear guide link with a length less than the front guide link and a front end and a rear end rotatably connected to a second coupling portion separated from the first coupling portion and the link base, respectively.

Abstract: Provided is an armrest structure for a vehicle seat, and more particularly, an armrest structure for a vehicle seat, which may be operated even though a button is pushed less than a button of a structure in the related art, such that a likelihood of the occurrence of abnormal noise may be reduced because of the reduction in stroke when the button is pushed, and a user may operate the armrest structure with a smaller effort.
