Abstract

The present invention relates to a ventilated armrest console comprising an armrest that is openably coupled to a console body, an air intake passage connected to the console body, and a control unit for opening, closing, and controlling the air intake passage. The armrest includes a lower cover and an upper cover, and air introduced through a first through-hole of the lower cover is discharged toward the occupant through a second through-hole of the upper cover. The air intake passage is equipped with a control unit comprising a rotating shaft and an opening/closing member, so that the opening amount of the air passage is controlled according to rotational operation. The control unit may operate automatically or semi-automatically through a button unit linked to the opening and closing of the armrest and a return spring member, and if necessary, the rotating shaft may further include a damping unit composed of a first gear and a second gear with different gear ratios, a sealing member in close contact with the inner surface of the air intake passage, or a link structure for simultaneously opening and closing a plurality of air passages. Accordingly, the present invention provides direct ventilation from the upper surface of the armrest, improves operability, reduces air leakage and noise, and enables uniform air distribution across a plurality of air passages.

Description

Armrest The present invention relates to an armrest provided in a vehicle door trim, and more specifically, to an armrest equipped with air cells to implement a massage function. Vehicle door trims typically finish the internal structure of the door, accommodate functional components such as switches and handles, and feature an armrest to support the passenger's arm. Conventional door trim armrests were mostly made of an integrated structure fixed to the vehicle body. In other words, the armrest was either integrally molded as part of the door trim or had a cushioning section composed of a foam pad and skin attached in a fixed state, maintaining a structure that always had the same height and shape. While these fixed armrests have the advantage of a simple structure and ease of manufacturing, there was a problem in that they caused fatigue or discomfort due to continuous pressure when a user's arm rested on the armrest for a long time. In particular, even though blood flow could be restricted or numbness in the arms could occur during long-distance driving, existing armrests provided only simple fixed cushions and did not have the function to actively relieve user fatigue. Meanwhile, although there are cases where air-cell massage functions using air have been applied to the seat backs or cushions, this is limited to the seat structure, and there have been no instances of air cells being applied to the door trim armrests. This is because there were structural constraints that made it difficult to incorporate a fluid pressure device into the door trim, as the space inside the door is narrow and components such as window regulators, speakers, and wiring are concentrated there. Therefore, in the prior art, no armrest has been proposed that is structured to be installed on a door trim and provides a massage function by being equipped with an air cell to press or relax the arm according to expansion and contraction. In addition, since the door trim armrest is a component linked to the opening and closing of the vehicle, a stable sealing structure and smooth opening and closing operation must be ensured simultaneously; however, this was also difficult to achieve with existing fixed structures. Therefore, there is a need for an armrest installed on the door trim that can solve the aforementioned problems.
