Description

TECHNICAL FIELD

The present disclosure relates to a foreign substance blocking and hidden wiring structure of a seat long-rail, and more particularly, to a foreign substance blocking and hidden wiring structure of a seat long-rail, which prevents introduction of foreign substances using slide blocks blocking a slot portion of a lower rail and prevents exposure of a wiring to the outside by placing the wiring in an inner space in a lower cover.

BACKGROUND ART

Generally, a seat of a vehicle is mounted so as to be slidable to the front and rear sides of the vehicle body, and such sliding movement is performed by a seat rail. Typically, in the case of a passenger vehicle provided with two rows of seats, a short rail is used to move a driver seat and a passenger seat, and in the case of a leisure vehicle provided with two or more rows of seats, short rails are applied to the first and second rows of seats to move the same, and long rails are applied to the third and subsequent rows of seats to move the same.

Here, the seat rail of the vehicle is configured to allow an upper rail coupled to a seat cushion frame to slide along a lower rail coupled to a floor panel of the vehicle body, and includes a lock mechanism that restrains free movement of the upper rail.

In addition, in order to enable a user to more conveniently use the forward-backward movement function of the seat, a forward-backward moving device is driven by a motor. In particular, in order to move the upper rail forward and backward using a motor, wires through which power is applied to the motor and a control signal is transmitted to the motor to move the upper rail are required. In general, in a vehicle, a set of electric wirings for supply of power to electric devices of a vehicle body is referred to as a wiring harness.

Meanwhile, in the era of autonomous vehicles, the interior of the vehicle is a concept of a moving space in which a user in the vehicle freely reads, rests, or conducts business. Since seats are located at the center of this space, a swivel mechanism configured to rotate a driver seat 180 degrees to transition to a meeting mode and a long-slide mechanism configured to move a seat to transition to a loading mode have attracted remarkable attention.

In the case of a seat of an autonomous vehicle, a power long-rail is embedded below a carpet, and the stroke of the rail is increased in order to improve passenger convenience. In this case, an exposed section of a slit portion of a lower rail of the seat and an exposed section of a wiring are also increased in proportion to the increase in stroke. Therefore, there are problems in that foreign substances may be introduced through the exposed slit portion of the lower rail and the exposed wiring may be damaged by external force applied thereto.
