Abstract: The wiring-harness routing device 1 includes two wiring harness 10, a support body 3 mounted slidably at a rail 2 and supporting a seat, and a protector 4 sliding interlockingly with the support body 3 and leading the two wiring harnesses 10 to the seat. The protector 4 includes a pair of wiring-harness hold portion 43 holding the two wiring harnesses 10 led through an opening 20 into the rail 2 to be arranged in parallel; a lead portion arranged between the pair of wiring-harness hold portions 43, and passing the two wiring harnesses 10 therethrough, and extending with a cylindrical shape so as to go through the slit and be led to an outside of the rail 2; and a mount portion 68 attached at the support body 3 so as to have a gap allowing motion in the widthwise direction of the rail 2.

Abstract: A retractable vehicle seat in which a seat main body disposed on a vehicle floor is flipped up laterally, so as to be retracted in a vehicle interior side wall of which the upper portion is inwardly inclined, may include a connection mechanism that is configured to rotatably connect the seat main body to a support stand. The connection mechanism includes a four-link mechanism having a stationary link integral with the support stand, an intermediate link integral with the seat main body, and a first link and a second link that connect these two links. The second link is configured to increase an angle between the first link and the intermediate link as the seat main body is flipped up.
