Description

Technology Field

[0001] The present invention relates to an electric seat installed in the second and third rows of an RV and SUV vehicle, and more specifically, to a rotating structure of the backrest of an electric seat for a vehicle that can lower the height of the backrest and headrest to secure a rear view through the rearview mirror while driving, and can form a longer and more comfortable sleeping space while camping. Background Technology

[0002] Generally, 5- or 7-seater RVs and SUVs are designed to allow for the loading of large items by folding down the second or third row seats to form a flat surface consisting of the backs of the seats and the trunk floor. Recently, the popularity of "car camping"—a leisure activity where a mat is laid on this flat surface to create a space for a person to lie down—has further increased the utility of SUVs.

[0003] In contrast, although 9-seater MPVs (Multi Propose Vehicles) have a more spacious interior than SUVs, it is difficult to secure a flat surface, so consumers who prefer car camping tend to prefer SUVs over MPVs.

[0004] Accordingly, attempts are being made to modify the interior of MPVs to enable car camping. Published Utility Model Publication No. 20-2021-0000654, 'Third row reverse seats of a four-row passenger van,' discloses a method of arranging the third row in a reverse direction.

[0005] This is advantageous in that it can provide a flat surface without altering the seat arrangement inside the vehicle, but due to the curvature of the seats themselves, this method makes it difficult to provide the space for car camping that consumers desire.

[0006] Meanwhile, a method is being proposed to remove the third and fourth row seats provided in MPV vehicles, install a wide seat equipped with a flat seat base, a flat seat backrest, a flat under support, and a flat headrest, and then unfold it to provide a flat surface suitable for car camping.

[0007] However, in order to secure a flat surface of 180 cm in length required for car camping when unfolded, this method causes various problems as the lengths of the seat base, seat back, under support, and / or headrest increase.

[0008] Specifically, in the case of the seat base and seat back, if the length is increased beyond an appropriate level, the user's seating comfort is significantly reduced, and if the length of the under support is increased, the under support part cannot be folded vertically and is installed at an angle, and if the length of the headrest is increased, it loses its function as a headrest, the upper part touches the ceiling of the vehicle, and it becomes difficult to look at the rear through the rearview mirror. The problem to be solved

[0009] The present invention aims to solve the aforementioned problems by providing a rotational structure for a vehicle electric seat backrest that is improved to allow the height of the backrest and head rate to be lowered while driving, thereby ensuring a rear view through the rearview mirror.

[0010] In addition, another objective of the present invention is to provide a rotating structure for an electric seat backrest for a vehicle that is improved to allow the length to be extended compared to a conventional seat when the backrest is unfolded during camping, thereby creating a more comfortable sleeping space. means of solving the problem

[0011] The rotation structure of the backrest of an electric seat for a vehicle according to the present invention is an electric seat for a vehicle in which a support plate that rotates up and down is coupled to the front of the seat and a backrest that can rotate forward and backward is coupled to the rear of the seat, wherein a motor box is coupled to both sides of the seat frame, and a rotating member is coupled to the motor box so as to rotate forward and backward, and a backrest frame is coupled to the rotating member so as to rotate, and the rotating member rotates backward during driving to lower the height of the backrest frame so as to secure a rear view through the rearview mirror, and the sleeping space can be expanded by the rotating member and the backrest frame rotating backward, and is characterized by having a guide member formed on the upper side of the motor box so as to maintain a vertical position when the rotating member rotates forward. Effects of the invention

[0012] According to the rotation structure of the electric seat backrest for a vehicle according to the present invention, the backrest frame is coupled to a rotating member configured to rotate forward and backward, thereby allowing the backrest frame to rotate forward and backward. When the rotating member is rotated backward to maintain a horizontal position, the height of the backrest frame and the headrest is lowered, thereby providing the effect of securing a rear view through the rearview mirror while driving.

[0013] In addition, when the rotating member and backrest frame are rotated backward, there is an advantage of being able to enjoy a more comfortable camping experience by securing a longer sleeping space than when a conventional electric seat is unfolded. Brief explanation of the drawing
